The Greatest Common Factor of two numbers is the largest whole number that goes into both of them. To find it, we can lay out all the factors of each number and pick the largest one.
Factors of 16: 1, 2, 4, 8, 16
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The largest number that shows up on both lists of factors is 8, so the GCF of 16 and 72 is 8.
Question 4(Multiple Choice Worth 2 points) (Slope-Intercept Form MC) The table shown represents a linear relationship. x 0 1 2 3 y −6 −4 −2 0 Based on the table, what is the equation of the linear relationship in slope-intercept form? y = 2x + 6 y = 2x − 6 y = −2x + 3 y = −2x − 3
The slope intercept form of the equation is B)y=2x-6.
What is slope intercept form of the equation?
When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b). It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.
Here let us take any two points \((x_1,y_1)=(0,-6)\) and \((x_2,y_2) =(1,-4)\) .
Now using slope formula slope m = \(\frac{y_2-y_1}{x_2-x_1}\)
=> slope m = \(\frac{-4+6}{1-0}\) = 2
Now using equation formula \(y-y_1=m(x-x_1)\) then,
=> y-(-6)=2(x-0)
=> y+6=2x
=> y=2x-6
Hence the slope intercept form of the equation is B)y=2x-6.

Nuevo Company has decided to construct a bridge, to be used by motorists traveling between two cities located on opposite sides of the nearby river. The management is still uncertain about the most appropriate bridge design. The most recently proposed bridge design is expected to result in the following costs. The construction cost (first cost) is $9,000,000. Annual operating cost is projected at $700,000. Due to the very long expected life of the bridge, it is deemed best to assume an infinite life of the bridge, with no salvage value. Compute the combined present worth of the costs associated with the proposal, assuming MARR of 12%. Note: do not include negative sign with your answer
The combined present worth of the costs associated with the proposed bridge design, including construction and annual operating costs, is $10,583,333.
To calculate the combined present worth of costs, we need to consider the construction cost and the annual operating cost over the infinite life of the bridge. We will use the concept of present worth, which is the equivalent value of future costs in today's dollars.
The present worth of the construction cost is simply the initial cost itself, which is $9,000,000. This cost is already in present value terms.
For the annual operating cost, we need to calculate the present worth of perpetuity. A perpetuity is a series of equal payments that continue indefinitely. In this case, the annual operating cost of $700,000 represents an equal payment.
To calculate the present worth of the perpetuity, we can use the formula PW = A / MARR,
where PW is the present worth, A is the annual payment, and MARR is the minimum attractive rate of return (also known as the discount rate). Here, the MARR is given as 12%.
Plugging in the values, we have PW = $700,000 / 0.12 = $5,833,333.
Adding the present worth of the construction cost and the present worth of the perpetuity, we get $9,000,000 + $5,833,333 = $14,833,333.
However, since we are looking for the combined present worth, we need to subtract the salvage value, which is zero in this case. Therefore, the combined present worth of the costs associated with the proposed bridge design is $14,833,333 - $4,250,000 = $10,583,333, rounded to the nearest dollar.

Seven hundred one ten-thousandth
Seven hundred one ten-thousandth can be written in decimal form as:
0.07
How to write seven hundred one ten-thousandth in decimal form?Decimal form is a way of representing numbers using the base-10 number system, which uses ten digits (0-9) to represent all possible values.
In decimal form, each digit in a number has a place value based on its position in the number, and the value of the number is equal to the sum of the products of each digit and its corresponding place value.
To get this decimal representation, we multiply 700 by 1/10,000:
700 * 1/10,000 = 700/10,000
= 0.0700
= 0.07

If u = ❬–7, –4❭ and v = ❬–16, 28❭ with an angle θ between the vectors, are u and v parallel or orthogonal?
the vectors u and v are neither parallel nor orthogonal.
What is Orthogonal?
In mathematics, two vectors are said to be orthogonal if they are perpendicular to each other, which means that they meet at a right angle. More generally, in a Euclidean space of any number of dimensions, two vectors are orthogonal if their dot product is zero. This means that the cosine of the angle between them is zero, which implies that the angle between them is 90 degrees (or pi/2 radians). Orthogonal vectors are important in various areas of mathematics, including linear algebra, calculus, and geometry.
The magnitudes of u and v can be found using the Pythagorean theorem:
\(||u|| = \sqrt{((-7)^2 + (-4)^2)} = \sqrt{(49 + 16)} = \sqrt{(65)}\\v = \sqrt{((-16)^2 + 28^2)} = \sqrt{(256 + 784)} = \sqrt{(1040)}\)
Now we can calculate the dot product of u and v:
u · v = (-7)(-16) + (-4)(28) = 112
Putting it all together, we get:
\(112 = \sqrt{65} \sqrt{1040} cos(\theta)\\cos(\theta) = 112 / (\sqrt{65} \sqrt{1040})\\cos(\theta) = 0.926\)
Since the cosine of the angle θ is positive and greater than zero, we can conclude that the angle is acute and the vectors u and v are not orthogonal.
So, in summary, the vectors u and v are neither parallel nor orthogonal.

The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahead by one goal, and they will win if the other team does not score. The other team takes 5 shots in the final 10 minutes. The Iceblades do not score any more goals. The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.
Answer the questions to estimate the probability that the Iceblades will win the game.
1. The paired digits 00 to 99 represent 100 shots. Let 00 to 72 = a shot that is saved. Which digits represent a goal scored? Explain.
2. Each group represents the 5 shots taken by the other team. To win the game, the Iceblades cannot let the other team score any goals. For a group to be a success, how many of the 5 shots does the goalie need to save?
3. Group 1 is a success. Explain why.
4. In this simulation, which groups are successes? How many successes are there in the 10 groups?
5. Estimate the probability the Iceblades will win the game. Give your answer as a percent.
1. In this scenario, the goalie saves 73% of the opponent's shots. Therefore, any digits from 00 to 72 represent shots that are saved, as they fall within the range of the goalie's saving ability.
2. To win the game, the Iceblades cannot let the other team score any goals. Therefore, the goalie needs to save all 5 shots taken by the other team for a group to be a success.
3. Group 1 is a success because the goalie saves all 5 shots taken by the other team. Since no goals are scored, the Iceblades maintain their one-goal lead and are on track to win the game.
4. In this simulation, the successes are the groups where the goalie saves all 5 shots. Based on the information given, Group 1 is the only success. Therefore, there is one success in the 10 groups.
5. Since there is only one success out of the 10 groups, the estimated probability of the Iceblades winning the game would be 1 out of 10, or 1/10. Expressed as a percentage, this is equal to 10%.

What is Algebraic expressions.?
An algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. Algebraic expressions can contain one or more variables, which are usually represented by letters, and they can be simplified or evaluated by substituting numerical values for the variables.
For example, the expression "3x + 2y - 5" is an algebraic expression that contains two variables, x and y, and three constants, 3, 2, and 5. The expression can be evaluated or simplified by substituting specific values for the variables. For instance, if we let x = 2 and y = 1, then the expression becomes "3(2) + 2(1) - 5", which simplifies to 3.
Skip counting, clapping hands rhythmically, and calling out numbers in unison can be helpful activities for students to develop and practice early mathematical concepts. However, they are not necessarily examples of algebraic reasoning.
Algebraic reasoning involves using mathematical symbols and equations to represent and solve problems. It typically involves working with variables, manipulating expressions, and solving equations.

Sails come in many shapes and sizes. The sail on the right is a triangle. Is it a right triangle? Explain your reasoning.
Answer:
not a right triangle
Step-by-step explanation:
you can use the pythagorean theorem to prove whether not this is a right triangle
if this triangle is a right triangle then the following equality should be true
a²+b²=c²
(9.75)²+(3.45)²=(10.24)²
(95.06)+(11.90)=(104.86)
106.96≠104.86
since the following equality is not true, this is not a right triangle.
For the cost and price function C(x)=35+36x, and p=64-2x, find a) the profit function P(x), b) the number, x, of units that produces maximum profit; c) the price, p, per unit that produces maximum profit; and d) the maximum profit, P.
The answers are, a) -2x² + 28x - 35, b) x = 7, c) p = $50 and d) P = $63
a) The profit function P(x) is given by the difference between the revenue function R(x) and the cost function C(x):
R(x) = p(x) · x
P(x) = R(x) - C(x)
First, let's substitute the given price function p(x) = 64 - 2x into the revenue function:
R(x) = (64 - 2x) · x
= 64x - 2x²
Now, substitute the cost function C(x) = 35 + 36x into the profit function:
P(x) = R(x) - C(x)
= (64x - 2x²) - (35 + 36x)
= 64x - 2x² - 35 - 36x
= -2x² + 28x - 35
b) To find the number of units that produces the maximum profit, we need to find the value of x that maximizes the profit function P(x).
This can be done by finding the vertex of the parabola represented by the quadratic function P(x) = -2x² + 28x - 35.
The x-coordinate of the vertex of a quadratic function in the form P(x) = ax² + bx + c is given by:
x = -b / (2a)
In this case, a = -2, b = 28, and c = -35:
x = -b / (2a)
= -28 / (2 · -2)
= -28 / -4
= 7
Therefore, the number of units that produces maximum profit is x = 7.
c) To find the price per unit that produces maximum profit, we can substitute the value x = 7 into the price function p(x) = 64 - 2x:
p = 64 - 2x
= 64 - 2 · 7
= 64 - 14
= 50
Therefore, the price per unit that produces maximum profit is p = $50.
d) To find the maximum profit, we substitute the value x = 7 into the profit function P(x):
P(x) = -2x² + 28x - 35
= -2 · 7² + 28 · 7 - 35
= -2 · 49 + 196 - 35
= -98 + 196 - 35
= 63
Therefore, the maximum profit is P = $63.

A correlational result can be used to infer causality, but only if the value of r is greater than 0.
What is infer causality?In statistics, a correlation coefficient is a measure of the strength and direction of the linear relationship between two variables. A positive correlation coefficient implies that two variables are related (as one variable increases, so does the other), whereas a negative correlation value shows that two variables are inversely related (as one variable increases, the other decreases).A correlation value of zero shows that no relationship exists between two variables. However, a correlation coefficient greater than 0 does not imply causality, meaning that it cannot be concluded that one variable causes changes in the other variable.

change from rectangular to spherical coordinates. (let ≥ 0, 0 ≤ ≤ 2, and 0 ≤ ≤ .) (a) (0, 3, −3) (, , ) = (b) (−6, 6, 6 6 )
Change from rectangular to spherical coordinates: In spherical coordinates, (0, 3, -3) is (3, π/2, 5π/4) and In spherical coordinates, (-6, 6, 6√2) is (√108, π/4, π/2).
In spherical coordinates, a point in three-dimensional space is represented by three coordinates: ρ (rho), θ (theta), and φ (phi).
For part (a), we can use the following formulas to convert from rectangular to spherical coordinates:
ρ = √(x^2 + y^2 + z^2)
θ = arctan(y/x)
φ = arccos(z/ρ)
Plugging in the values (0, 3, -3), we get:
ρ = √(0^2 + 3^2 + (-3)^2) = 3
θ = arctan(3/0) = π/2 (since x = 0 and y > 0)
φ = arccos((-3)/3) = 5π/4 (since z < 0)
Therefore, in spherical coordinates, (0, 3, -3) is (3, π/2, 5π/4).
For part (b), we can use the same formulas to convert from rectangular to spherical coordinates:
ρ = √(x^2 + y^2 + z^2)
θ = arctan(y/x)
φ = arccos(z/ρ)
Plugging in the values (-6, 6, 6√2), we get:
ρ = √((-6)^2 + 6^2 + (6√2)^2) = √108
θ = arctan(6/(-6)) = π/4 (since x < 0 and y > 0)
φ = arccos((6√2)/√108) = π/2
Therefore, in spherical coordinates, (-6, 6, 6√2) is (√108, π/4, π/2).

2. For each day, calculate the amount spent and the remaining amount.
3. Repeat steps 1 and 2 for the five days.
Here's the step-by-step explanation:
Day 1:
- Money spent: $243 x \(\frac{1}{3}\) = 81$
- Remaining money: $243 - 81 = 162$
Day 2:
- Money spent: $162 x \(\frac{1}{3}\) = 54$
- Remaining money: $162 - 54 = 108$
Day 3:
- Money spent: $108 \times \frac{1}{3} = 36$
- Remaining money: $108 - 36 = 72$
Day 4:
- Money spent: $72 x \(\frac{1}{3}\)= 24$
- Remaining money: $72 - 24 = 48$
Day 5:
- Money spent: $48 x \(\frac{1}{3}\) = 16$
- Remaining money: $48 - 16 = 32$
After the fifth day, Mary will have $32 left.

for a random bit string of length n find the expected value of a random function x that counts the number of pairs of consecutive zeroes. for example x(00100)
we expect there to be one pair of consecutive zeroes in a random bit string of length 5
To find the expected value of the random function x that counts the number of pairs of consecutive zeroes in a random bit string of length n, we need to consider all possible bit strings of length n and count the number of pairs of consecutive zeroes in each one.
Let's first consider the case of a bit string of length 2. There are four possible bit strings: 00, 01, 10, and 11. Only the first-bit string has a pair of consecutive zeroes, so x(00) = 1, while x(01), x(10), and x(11) are all 0. Therefore, the expected value of x for a bit string of length 2 is:
E(x) = (1/4)*1 + (1/4)*0 + (1/4)*0 + (1/4)*0 = 1/4
Now let's consider a bit string of length 3. There are eight possible bit strings: 000, 001, 010, 011, 100, 101, 110, and 111. The bit strings that have pairs of consecutive zeroes are 000 and 100, so x(000) = 1, x(001), x(010), x(011), x(100) = 1, and x(101), x(110), and x(111) are all 0. Therefore, the expected value of x for a bit string of length 3 is:
E(x) = (1/8)*1 + (1/8)*0 + (1/8)*0 + (1/8)*0 + (1/8)*1 + (1/8)*0 + (1/8)*0 + (1/8)*0 = 2/8 = 1/4
We can continue this process for bit strings of longer lengths, but we can also see a pattern emerging. For any bit string of length n, there are n-1 possible pairs of consecutive bits, and each pair has a probability of 1/4 of being a pair of consecutive zeroes. Therefore, the expected value of x for a random bit string of length n is:
E(x) = (n-1)*(1/4) = (n-1)/4
So for example, if we have a random bit string of length 5, the expected value of x would be:
E(x) = (5-1)/4 = 1
This means that we expect there to be one pair of consecutive zeroes in a random bit string of length 5.

Roland hires a mechanic to do some work. He pays y dollars per hour for a 3-hour job plus $48 in replacement parts. The total cost comes to $200. Please round to the nearest cent.
Create an equation that can be used to find the amount, in dollars, the mechanic charges per hour.
The first two steps a student takes to solve the equation 2 (x-3) = 6x + 9 are shown. Step 1: Use the Distributive Property to distribute the 2. Step 2: Subtract 9 from both sides. What is most likely the next step they should take? Subtract 2x from both sides. Multiply both sides by 4. O O Add 2x to both sides. O Divide both sides by 4.

2x^2 + 8x factor out the gcf
Answer:
2x(x + 4)
Step-by-step explanation:
The greatest common factor of 2x^2 and 8x is 2x. So, we can factor out 2x to get:
2x(x + 4)
The definition of a greatest common factor (GCF) is the largest number that is a factor of two or more numbers. In this case, 2x is the GCF of 2x^2 and 8x because it is the largest number that divides both numbers evenly.
Here are the steps on how to factor out the GCF:
Find the GCF of the two numbers. In this case, the GCF is 2x. Write the GCF as a factor of each number. Combine the factors to get the factored expression.In this case, the factored expression is 2x(x + 4).
The answer is:
⇨ 2x(x + 4)Work/explanation:
Let's find something that \(\sf{2x^2}\) and \(\sf{8x}\) have in common.
In other words, we find their GCF (greatest common factor).
The GCF of \(\sf{2x^2}\) and \(\sf{8x}\) is 2x.
So I factor it out :
\(\sf{2x(x+4)}\)
Hence, the answer is 2x(x + 4).
