It says mr fuller wants to put fence around his rectangular yard. The length is 75 and the width is 55.
Answer:
Step-by-step explanation:
You have omitted relevant parts of the question. What is the question? Are you looking for the area of the yard? The amount of fencing needed?
What units are used? (Feet, yards, meters, etc.)
area of yard = 75×55 = 4125 units²
amount of fencing needed = perimeter of rectangle = 2(75+55) = 260 units.
The total length of the fencing is the perimeter of the rectangular yard which is P = 260 feet
What is the Perimeter of a Rectangle?The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P = 2 ( Length + Width )
Given data ,
The width of the rectangular yard W = 55 feet
The length of the rectangular yard L = 75 feet
Let the perimeter of the rectangular yard be = P
And , the required fencing = Perimeter of rectangular yard
Perimeter of rectangular yard P = 2 ( L + W )
Substituting the values in the equation , we get;
Perimeter of rectangular yard P = 2 ( 55 + 75 )
Perimeter of rectangular yard P = 2 ( 130 )
Perimeter of rectangular yard P = 260 feet
Therefore , the value of P is 260 feet

Answer:
The rate of change of f(x) is greater than that of g(x)
They have the same y intercept of 14
Step-by-step explanation:
Given
\(g(x) = -\frac{1}{2}x + 14\)
Table for function f(x)
Required
Compare their rate of change and intercept
For g(x), we have:
\(g(x) = -\frac{1}{2}x + 14\)
The form of an equation is:
\(y = mx + b\)
Where
\(m = slope\)
\(b =y\ intercept\)
So:
\(m = -\frac{1}{4}\)
\(b = 14\)
For f(x): Start by calculating the slope (m)
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
\(m = \frac{17-16}{6-4}\)
\(m = \frac{1}{2}\)
The intercept is calculated using:
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
Where
\((x_1,y_1) = (-2,13)\)
\((x_2,y_2) = (0,y)\) --- we want to solve for y
So:
\(\frac{1}{2} = \frac{y - 13}{0 --2}\)
\(\frac{1}{2} = \frac{y - 13}{2}\)
Multiply both sides by 2
\(1 =y - 13\)
Make y the subject
\(y =1 + 13\)
\(y = 14\)
So, we have:
\(m = -\frac{1}{4}\) and \(b = 14\) -- for g(x)
\(m = \frac{1}{2}\) and \(y = 14\) --- for f(x)
By comparison:
The rate of change (i.e. slope) of f(x) is greater than that of g(x) because \(1/2 > -1/2\)
They have the same y intercept of 14

A sphere of radius "r" is cut by a plane "h" units above the equator. To find the volume of the solid (spherical segment) above the plane, we first need to find the height of the segment, which is (r - h). Then, we can use the formula for the volume of a spherical segment: \((1/3) * \pi * (r^2 - (r-h)^2) * h.\)
A manufacturer drills a hole through the center of a metal sphere of radius R. The hole has a radius r. To find the volume of the resulting ring, we can use the formula for the volume of a cylindrical ring: \(\pi * (R^2 - r^2) * h\), where h is the height of the ring. Since the hole goes all the way through the sphere, the height of the ring is equal to the radius of the sphere, R. So the volume of the ring is \(\pi * (R^2 - r^2) * R\).
In the first problem, the volume of the solid (spherical segment) above the plane is \((1/3) * \pi * (r^2 - (r-h)^2) * h\). In the second problem, the volume of the resulting ring is \(\pi * (R^2 - r^2) * R.\)

True
False
Answer:
True
Step-by-step explanation:
We use definitions to help us in this problem. The definition of an integer is a whole number that is not a fraction or has any fractional value. This definition includes all whole numbers, so we know that all whole numbers can be classified as integers. That's one condition done. The definition of a rational number is a number that can be written as a fraction. All whole numbers can be written as a fraction (i.e. 12/1, -3/1, 10000/1). This means that all whole numbers are also rational numbers, giving us our final answer of True.

A bag contains 6 batteries, all of which are the same size and are equally likely to be selected. Each battery is a different brand. If you select 3 batteries at random, use the counting principle to determine how many points will be in the sample space if the batteries are selected
Answer:
there are 120 possible points in the sample space if we select 3 batteries at random from a bag containing 6 batteries of different brands.
Step-by-step explanation:
The counting principle states that if there are n ways to do one thing and m ways to do another, then there are n x m ways to do both.
In this case, we want to determine how many ways we can select 3 batteries out of 6. Using the counting principle, we can break down the selection process into three steps:
Select the first battery. There are 6 choices for the first battery.
Select the second battery. There are 5 choices left for the second battery, since we've already selected one.
Select the third battery. There are 4 choices left for the third battery.
Using the counting principle, we can multiply the number of choices for each step to get the total number of ways to select 3 batteries:
6 x 5 x 4 = 120
Therefore, there are 120 possible points in the sample space if we select 3 batteries at random from a bag containing 6 batteries of different brands.

Step-by-step explanation:
We want to find the area of both triangles seprately than add them together. For the area of a traingle, we use the equation 1/2 base times height. For triangle ABE we do this:
\(A = \frac{1}{2} (12)(4)\)
\(A = (6) (4)\)
\(A = 24\)
For triangle BDC, we do this:

Suppose that weekly income of migrant workers doing agricultural labor in Florida has a distribution with a mean of $520 and a standard deviation of $90. A researcher randomly selected a sample of 100 migrant workers. What is the probability that sample mean is less than $500
Answer:
\( z = \frac{500-520}{\frac{90}{\sqrt{100}}}= -2.22\)
And we can find this probability using the normal standard distribution and we got:
\( P(z<-2.22) =0.0132\)
Step-by-step explanation:
For this case we have the foolowing parameters given:
\( \mu = 520\) represent the mean
\( \sigma =90\) represent the standard deviation
\( n = 100\) the sample size selected
And for this case since the sample size is large enough (n>30) we can apply the central limit theorem and the distribution for the sample mean would be given by:
\( \bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}}) \)
And we want to find this probability:
\( P(\bar X <500)\)
We can use the z score formula given by:
\( z = \frac{500-520}{\frac{90}{\sqrt{100}}}= -2.22\)
And we can find this probability using the normal standard distribution and we got:
\( P(z<-2.22) =0.0132\)
Rewrite as a piece wise function y=1/2 |x-6| +4
Answer:
y = {-1/2x +7 for x < 6; 1/2x +1 for x ≥ 6}
Step-by-step explanation:
You want y = 1/2|x -6| +4 written as a piecewise function.
DomainsThe absolute value function changes its definition when its argument is negative:
y = |x| ⇒ y = -x for x < 0, and y = x for x ≥ 0
This means our piecewise function will have one definition for (x-6) < 0 and another for (x -6) ≥ 0.
For x -6 < 0The argument is negated in this domain, so we have ...
y = -1/2(x -6) +4
y = -1/2x +3 +4
y = -1/2x +7
For x -6 ≥ 0The absolute value function is an identity function in this domain:
y = 1/2(x -6) +4
y = 1/2x -3 +4
y = 1/2x +1
Piecewise functionCombining these descriptions into one, we have ...
\(\boxed{y=\begin{cases}-\dfrac{1}{2}x+7&\text{for }x < 6\\\\\dfrac{1}{2}x+1&\text{for }x\ge6\end{cases}}\)

Convert the rectangular coordinates to polar coordinates
(1, -9)
The polar coordinates of (1, -9) are (9.06, -1.47 radians).
To convert from rectangular coordinates to polar coordinates, we can use the following formulas:
r = √(x² + y²)
θ = tan⁻¹(y/x)
where r is the distance from the origin to the point, and θ is the angle between the positive x-axis and the line connecting the origin to the point.
In this case, x = 1 and y = -9. Plugging these values into the formulas, we get:
r = √(1² + (-9)²) = √82 ≈ 9.06
θ = tan⁻¹((-9)/1) ≈ -1.47 radians
Therefore, the polar coordinates of (1, -9) are (9.06, -1.47 radians). The distance from the origin to the point is approximately 9.06 units, and the angle between the positive x-axis and the line connecting the origin to the point is approximately -1.47 radians (or approximately -84.26 degrees).

if the supply and demand functions for a commodity are given by p-q=10 and q(2p-10)=2100, what is the equilibrium price and what is the corresponding number of units supplies and demanded
Answer:
If p - q = 10, then p = 10 + q. Replace the other p with this:
q(2(10 + q) - 10) = 3600
q(20 + 2q - 10) = 3600
q(10 + 2q) = 360
The equilibrium point of a demand and supply function is the point where both functions are equal.
The equilibrium price is 40, and the corresponding demand is 30 supplies
Given
\(p- q = 10\) --- the supply function
\(q(2p - 10) = 2100\) --- the demand function
Make q the subject in \(p- q = 10\)
\(q = p - 10\)
Substitute \(q = p - 10\) in \(q(2p - 10) = 2100\)
\((p - 10)(2p - 10) = 2100\)
Factor out 2
\(2(p - 10)(p - 5) = 2100\)
Divide both sides by 2
\((p - 10)(p - 5) = 1050\)
Open brackets
\(p^2 -10p - 5p + 50 = 1050\)
\(p^2 -10p - 5p + 50 - 1050 =0\)
\(p^2 -15p - 1000 =0\)
Expand
\(p^2 -40p + 25p- 1000 =0\)
Factorize
\(p(p -40) + 25(p- 40) =0\)
Factor out p - 40
\((p+ 25) (p- 40) =0\)
Solve for p
\(p = -25\) or \(p = 40\)
The price cannot be negative.
So: \(p =40\)
Recall that:
\(q = p - 10\)
\(q = 40 - 10\)
\(q = 30\)

range ---> ??
domain ---> ??
The Domain: (-∞, -3) ∪ (-3, 6) ∪ (6, ∞) and Range: (-∞, 0) ∪ (0, ∞).
What is domain?
The domain of a function refers to the set of all possible input values (also known as the independent variable) for which the function is defined.
According to question:
In this case, the denominator of the function is a quadratic expression, and we know that dividing by zero is undefined. Therefore, we need to find the values of x that make the denominator equal to zero, and exclude those values from the domain.
To find the values that make the denominator equal to zero, we can factor it as follows:
x² - 3x - 18 = 0
(x - 6)(x + 3) = 0
So, the denominator is equal to zero when x = 6 or x = -3. Therefore, the domain of the function is all real numbers except x = 6 and x = -3.
Domain: (-∞, -3) ∪ (-3, 6) ∪ (6, ∞)
The range of a function consists of all possible output values of the function, given the domain of the function.
To find the range of this function, we need to analyze the behavior of the function as x approaches positive or negative infinity.
As x approaches positive infinity, both the numerator and denominator of the function approach positive infinity. Therefore, the function approaches zero.
As x approaches negative infinity, both the numerator and denominator of the function approach negative infinity. Therefore, the function approaches zero.
Since the function approaches zero as x approaches positive or negative infinity, we can say that the range of the function is all real numbers except zero.
Range: (-∞, 0) ∪ (0, ∞).

The run is 9x miles long, while the bike race is 22y miles long.
What is meant by distance?The distance between two points in mathematics is referred to as the distance. The distance formula, which is simply a derivation of the Pythagorean theorem, which is used to find the length of any one side of a right triangle when you know the lengths of the other two sides, can be used to calculate this distance.
Therefore,
d = vt
where:
d = distance (miles)
v = speed (mph)
t = time (hours)
Let x = run time
Let y = bike time
Total time: x + y = 4
We can create an equation that represents the formula using these variables.
d total = d bike + d run
49 = 9x + 22y
The equation is then only expressed in terms of x or y. We're going to get it in terms of x.
49 = 9x +22(4 - x)
49 = 9x + 88 - 22x
-39 = -13x
3 = x
To determine the distance between each part, enter this value of x into the variables.
run distance = 9x
bike distance = 22(4 - x)
Let x be run time, y be the bicycle race time.
Total time
x+y = 4
Run distance R = 9x
Bicycle race distance B = 22y
Total distance
9x + 22y = 49
Replace y in the second equation with 4 - x to solve this system.
You'll obtain
y = 1
x = 3
so
R = 9x = 27
B = 22y = 22
Hence, The run is 9x miles long, while the bike race is 22y miles long.

a high school sells students tickets for $5 as well as general admission tickets for $7 to attend thier football games. The school needs to bring in at least $1500 per game in order to maintain the costs of the football team
The cost of students ticket is $37.5and the cost of general admission is $187.5.
What is system of equations?A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system.
Assume s be the students tickets cost and g be the general admission cost.
From the given information,
⇒ s + g = 225 ..(1)
5s + 7g = 1500 ..(2)
From equation (1),
s = 225 - g
Plug the value of s in equation (2)
5(225 - g) + 7g = 1500
1125 - 5g + 7g = 1500
2g = 1500 - 1125
2g = 375
g = 187.5
Plug g = 125 in equation (1),
s + 187.5= 225
s = 225 - 187.5
s = 37.5
