The order of the numbers from least to greatest (pi, -3, sqrt 49 , sqrt 9) is -3.00 <  sqrt 9 < pi  < sqrt 9

The concept that will be used here is ordering. When you put a list of numbers in order, you rank them from least to greatest or greatest to least. An effective tool for comparing and sorting numbers is a number line. From left to right, we read a number line, with the numbers nearer to the left having lower values.

The given numbers can be converted to decimals so as to be able to arange them in the required order which can be done as :

pi= 3.147= 3.15

-3= -3.00

sqrt 49=7.00

sqrt 9 =3.00

Therefore,-3.00 <  sqrt 9 < pi  < sqrt 9

Step-by-step explanation:

The quotient of the given fractions is 6.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given that, 9/4 divided by 3/8.

When two fractions are divided, the first fraction is multiplied by the second fraction's reciprocal. Finding the reciprocal of the second fraction reversing its numerator and denominator is the first step in dividing fractions. Multiply the two numerators after that. Multiply the two denominators after that.

Here, 9/4 ÷ 3/8

= 9/4 × 8/3

= 3 × 2

= 6

Given:

The circumference of a circle is 32 cm.

To find:

The diameter of the circle.

Solution:

We know that, circumference of a circle is

\(C=2\pi r\)

It can be written as

\(C=\pi d\)              \([\because d=2r]\)

Where, r is the radius of the circle and d is the diameter of the circle.

The circumference of a circle is 32 cm.

\(32=\pi d\)

\(\dfrac{32}{\pi}=d\)

\(\dfrac{32}{3.14}=d\)

\(d\approx 10.19\)

Therefore, the diameter of the circle is about 10.19 cm.

The x-intercepts of the graph of the function are (-2, 0), (5, 0)

The midpoint of the x-intercept is 1.5.

The extremum of the function is a minimum and the value of x at which it occurs is k(1.5) = -61.25.

In Mathematics, the x-intercept is the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" or y-value is equal to zero (0).

In this exercise, we would use an online graphing calculator to plot the quadratic equation in order to determine the x-intercepts as shown in the graph attached below.

Therefore, the x-intercepts of the graph of the given quadratic equation k(x) = 5x² - 15x - 50 including the following:

Since a line of symmetry must lie in the middle of the x-intercepts, the symmetry is given by;

x = (-2 + 5)/2

x = 3/2

x = 1.5

For the extremum, we have;

k(1.5) = 5(1.5)² - 15(1.5) - 50

k(1.5) = 11.25 - 22.5 - 50

k(1.5) = -61.25

Answer:

\(C(m)=0.9m^2+0.25\)

Step-by-step explanation:

The surface area of a cube-shaped box with a side of m feet is given by the function:

\(S(m)=6m^2\)

The cost, C, in dollars, of wrapping a box with a surface area of x square feet is given by the function:

\(C ( x ) = 0.15 x + 0.25\)

We want to find an explicit expression that models the costs of wrapping a cube-shaped box with a side length of m feet.

In the cost function, C(x), x is the surface area, therefore:

\(S(m)=x;$ and$\\C ( S(m) ) = 0.15(6m^2) + 0.25\\C(m)=0.9m^2+0.25\)

To find the cost of wrapping a cube of side length m feet, we use the explicit function:

\(C(m)=0.9m^2+0.25\)  

The depth of the water at the point where the person is lying on the diving board can be determined using the given information: the person is 2.50 m above the surface of the water, and the apparent distance from the person to the penny on the bottom of the pool is 8.00 m.

To find the depth of the water, we can use the concept of apparent depth and the principles of geometric optics. Apparent depth refers to how an object appears to be at a different position due to the refraction of light when it travels from one medium (air) to another medium (water) of different refractive indices.

The formula for apparent depth is given by: Apparent depth = Actual depth / Refractive index

In this case, the apparent distance from the person to the penny is 8.00 m, which corresponds to the apparent depth. The actual depth is the distance from the surface of the water to the bottom of the pool, which we need to determine. The refractive index of water is approximately 1.33.

Plugging the values into the formula, we can solve for the actual depth:

8.00 m = Actual depth / 1.33

Rearranging the equation and solving for the actual depth:

Actual depth = 8.00 m × 1.33 ≈ 10.64 m

Therefore, the depth of the water at the point where the person is lying on the diving board is approximately 10.64 m.

The person has walked a total of 28 miles. To calculate total distance walked by the person, we add up the distances in each direction

5 miles East + 6 miles Southeast + 6 miles South + 7 miles Southwest + 4 miles East

When we add these distances together, we get:

5 + 6 + 6 + 7 + 4 = 28

Therefore, the person has walked a total of 28 miles.

In more detail, let's break down the distances walked in each direction:

- 5 miles East: This means the person walked 5 miles in the East direction.

- 6 miles Southeast: This means the person walked 6 miles in the direction that is both South and East.

- 6 miles South: This means the person walked 6 miles in the South direction.

- 7 miles Southwest: This means the person walked 7 miles in the direction that is both South and West.

- 4 miles East: This means the person walked 4 miles in the East direction.

By adding up these distances, we find that the person has walked a total of 28 miles.

Using Excel, the probability that 2 or fewer students are left-handed in a random sample of 70 students from a school where 10% of the students are left-handed can be calculated as approximately 0.9999.

To calculate the probability using Excel, we can utilize the binomial distribution function. The binomial distribution is appropriate for situations with a fixed number of independent trials (sampling 70 students) and two possible outcomes (left-handed or not left-handed).

In Excel, the formula to calculate the probability of 2 or fewer left-handed students can be written as "=BINOM.DIST(2, 70, 0.1, TRUE)". Here, "2" represents the number of left-handed students (or fewer) we want to calculate the probability for, "70" is the total number of students in the sample, and "0.1" is the probability of a student being left-handed (10% or 0.10).

Evaluating this formula in Excel yields a probability of approximately 0.9999 when rounded to four decimal places. This implies that there is an extremely high probability (close to 100%) of having 2 or fewer left-handed students in a random sample of 70 students from the school, given that the overall proportion of left-handed students in the school is 10%.

The future value of the item will be $2283676.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest. Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

Given,

P = $300,000

r = 7%

t = 30

Using simple interest:

P(1+r)^t

300000(1+ 0.07)^30

Simple interest is a simple and straightforward formula for figuring out how much interest will be charged on a loan. Simple interest is calculated by dividing the daily interest rate by the principle and the number of days between payments.

The principal amount must be multiplied by the time, interest rate, and time period in order to calculate simple interest. Simple Interest = Principal x Interest Rate x Time is the written formula.

Principal amount = $15,500

interest = $5,084

Time = ?

Rate = 4.1% simple interest

The probability of rolling a prime number and then rolling a prime number is:

= 2/5

Since, There are four prime numbers on a 6-sided die, which are 2, 3, 5, and 7.

So the probability of rolling a prime number on the first roll is,

= 4/6

= 2/3.

Assuming that the first roll was a prime number, there are now only five possible outcomes on the second roll, since we cannot roll the same number twice.

Of those, three are prime numbers, which are 2, 3, and 5.

So the probability of rolling a prime number on the second roll given that the first roll was a prime number is 3/5.

Hence, the probability of rolling a prime number and then rolling a prime number, we need to multiply the probability of rolling a prime number on the first roll (2/3) by the probability of rolling a prime number on the second roll given that the first roll was a prime number (3/5).

So, the probability of rolling a prime number and then rolling a prime number is:

= (2/3) x (3/5)

= 6/15

= 2/5

The height of the tree is 6.4m

the difference is that in one case the shadow of the tree is 60 - 20 = 40 m, and in the other case it is 60 + 20 = 80 m long.

anyway, for a certain angle of the sunlight we know the shadow of the pole is 60 m long, which creates with the 4.8 m height a right-angled triangle, with the line of sight from the top of the pole to the ground end of the shadow being the Hypotenuse or radius for or trigonometric triangle in a circle.

the shadow length (60 m) is sine of the sunshine angle multiplied by the radius.

the height (4.8 m) is cosine of that sunshine angle multiplied also by that radius.

Pythagoras gets us the radius for the pole triangle :

radius² = 60² + 4.8² = 3600 + 23.04 = 3623.04

radius = sqrt(3623.04) = 60.19169378... m

sin(angle) × radius = 60

sin(angle) = 60/radius = 0.996815279...

angle = 85.42607874...°

the sunshine creates with the tree also a right-angled triangle with the same sunshine angle (the sun is so far away, that the tiny, tiny difference is irrelevant, we can simply assume the angles are equal).

but the shadow is of different length (sin(angle)×radius), which means also the radius for the tree triangle has to be different. and that defines the height of the tree (cos(angle)×radius).

but now we know the angle, and we can reverse calculate the side lengths.

but the question is (as mentioned at the beginning) : is the tree shadow 40 m or 80 m long.

we have therefore 2 solutions for the height of the tree.

1. the shadow is 40 m long.

sin(angle) × radius = 40

radius = 40/sin(angle) = 40.12779585... m

tree height = cos(angle)×radius = 3.2 m

2. the shadow is 80 m long.

sin(angle) × radius = 80

radius = 80/sin(angle) = 80.25559171... m

tree height = cos(angle)×radius = 6.4 m

the solution w = -36 is correct

The given equation is w/4 + 16 = 7.The main objective here is to solve for the variable w. Let us see the step-by-step process to solve for w:

Step 1: Simplify the left side of the equation by subtracting 16 from both sides. w/4 + 16 = 7 ⇒ w/4 = -9The justification for subtracting 16 from both sides is the additive inverse property of equality, which states that if a = b, then a - c = b - c for any real number c.

Step 2: Multiply both sides of the equation by 4 to isolate w. w/4 = -9 ⇒ (4)(w/4) = (4)(-9) ⇒ w = -36The justification for multiplying both sides of the equation by 4 is the multiplication property of equality, which states that if a = b, then ac = bc for any real number c.

Step 3: Check the solution. Substitute -36 for w in the original equation to make sure it satisfies the equation. w/4 + 16 = 7 ⇒ (-36)/4 + 16 = 7 ⇒ -9 + 16 = 7 ⇒ 7 = 7Since 7 = 7 is a true statement, . The justification for this step is that it ensures that the solution obtained in the previous step is valid.

Suppose lnx - lny = y-4 and y is a differentiable function of x. The value of dy/dx when x=4 is 1/4.

To find the value of dy/dx, we can use the given equation and the ln formula to differentiate both sides with respect to x. This will give us:

lnx-lny = y-4

d/dx(lnx-lny) = d/dx(y-4)

1/x-1/y (dy/dx) = dy/dx

(1/x-1/y) dy/dx = 0

dy/dx=(1/x)/(1/y)

dy/dx=y/x

Since we are given that y=4 when x=4, we can substitute these values into the equation to find the value of dy/dx when x=4:

dy/dx=4/4

dy/dx=1/4

Therefore, the value of dy/dx when x=4 is 1/4.
