a formula for the perimeter of the rectangle in terms of its length, l will be given as l = P / 2 - b.
We know that the perimeter of rectangle is given by:
Perimeter ( P ) = 2 ( l + b )
Now, we need to represent this formula in terms of length that is l.
So, we get that:
P = 2 l + 2 b
Now subtract 2 b from both the sides:
P - 2 b = 2 l + 2 b - 2 b
P - 2 b = 2 l
2 l = P - 2 b
Divide both the sides by 2:
2 l / 2 = (P - 2 b) / 2
l = P / 2 - b
Therefore, we get that, a formula for the perimeter of the rectangle in terms of its length, l will be given as l = P / 2 - b.

A baseball coach spent $118.25 on 11 pizzas. Estimate ate the cost of each pizza using numbers with one nonzero digit. Then find the exact cost per pizza. Show all work
The baseball coach bought each pizza at an approximate cost of $ 10 or an exact cost of $ 10.75.
What is are the approximate and exact cost of each pizza bought by a baseball coach?
In this problem we know that a baseball coach spends a total of $ 118.25 on buying 11 pizzas. First, we need to estimate the amount of money spent per each pizza bought, which is found by means of multiplication tables and the supposition of truncation, that is, finding the maximum integer less than or equal to the real total cost.
By direct inspection we find that 10 times the 11 pizzas is equal to $ 110, which is the maximum integer less than or equal to the real total cost. Then, we estimate a cost of $ 10 per each pizza bought. Second, the exact unit cost is found by dividing the total by the number of pizzas:
c = $ 118.25 / 11
c = $ 10.75
In a nutshell, the baseball coach bought each pizza at an approximate cost of $ 10 or an exact cost of $ 10.75.

5. Kerry McCarthy is a news traffic reporter with an annual gross
pay of $44,500. He is single and is paid on a monthly basis.
How much is withheld monthly for state taxes?
$3,708.33 is withheld monthly for state taxes.
Some states have a graduated income tax that involves a different tax rate for each of several levels of income. The tax rate increases as income increases.
Tax Withheld per Pay Period = Annual Tax Withheld/ Number of Pay Periods per Year
Here, we are given that Kerry McCarthy is a news traffic reporter with an annual gross pay of $44,500.
Thus, the Annual Tax Withheld = $44,500.
He is paid on a monthly basis ⇒ Number of Pay Periods per Year = 12
Hence, we get-
Tax Withheld per Pay Period = 44,500/ 12
= 3,708.33
Thus $3,708.33 is withheld monthly for state taxes.

On which interval(s) is the function f(x) = x^3+3x^2−4x−12 increasing?
The interval at which the function x³ + 3x² - 4x - 12 increases is
x ∈ (- ∞, - 2.5) ∪ (0.5, ∞).
We have,
x³ + 3x² - 4x - 12
We need to draw a graph to see at which interval the graph is increasing.
The graph is given below.
We see that the graph is increasing from x = -∞ to x = -2.5 and from x = -2.5 it decreases till x = 0.5 and again from x = 0.5 it increases to x = ∞.
So we can write the interval as:
x ∈ (- ∞, - 2.5) and x ∈ (0.5, ∞)
We can write it as one single interval as:
S = (- ∞, - 2.5) ∪ (0.5, ∞)
Thus the interval at which the function x³ + 3x² - 4x - 12 increases is
x ∈ (- ∞, - 2.5) ∪ (0.5, ∞).

Use a graphing calculator to draw the graph of the model and, in the same viewing window, the scattergram of the data. Does the model fit the data well?
The function is not a good model for the data
The function is a good model for the data.
Estimate at what capacity U. S. nuclear power plants were working in 2014.
% Round to the nearest whole percent.
Predict when U. S. nuclear power plants will be working at full (100%) capacity.
Enter the year this occurs.
The function is a good model for the data, capacity U. S. nuclear power plants were working in 2014 is 115% and the year when nuclear power plant working with full capacity is 2008.
Given that the table which shows the capacities at which U.S. nuclear power plants are working and a model of the situation is f(t)=0.027t²+0.216t+53.296.
The Scatter plot for our function and points is shown in attached image and the point are highly related to the curve .
So the function is good model.
The year 2014 means t=2014-1970=44
So to get the population,put t=44 in equation
f(t)=0.027(44)²+0.216(44)+53.296
f(t)=0.027(1936)+0.216(44)+53.296
f(t)=52.272+9.504+53.296
f(t)=115.072
And on rounding it we get 115%.
Now, to find year at which capacity is 100% ,put f(t)=100 and solve for t
f(t)=0.027t²+0.216t+53.296=100
0.027t²+0.216t+53.296=100
0.027t²+0.216t+53.296-100=0
0.027t²+0.216t-46.704=0
Now, we will solve this using quadratic formula for f(x) =ax²+bx+c=0
[tex]\begin{aligned}x&=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}\end[/tex]
for our function a= 0.027 , b=0.216 ,c=-46.704 substitute this value and we get
[tex]\begin{aligned}t&=\frac{-0.216\pm \sqrt{(0.216)^2-4\times 0.027\times (-46.704)}}{2\times 0.027}\\ &=\frac{-0.216\pm \sqrt{0.046656+5.044032}}{0.054}\\ &=\frac{-0.216\pm \sqrt{5.090688}}{0.054}\\ &=\frac{-0.216\pm 2.256}{0.54}\\ &=37.78, -45.78\end[/tex]
As we all know time cannot be negative so t=-45.78 will be rejected.
So, t=37.78=38
Now, we will find the corresponding year
1970+38=2008
Hence, from the given table the function is a good model for the data, capacity U. S. nuclear power plants were working in 2014 is 115% and the year when nuclear power plant working with full capacity is 2008.

8 halls would be required to accommodate 520 people in the hall.
As we know that a hall can accommodate 65 people.
To determine the number of hall required for 520 people,
first we need to find that how many halls would be required for one person,
So, we will divide the 1 by 6 to find :
The number of one person accommodate = 1/65 Hall
Then, 520 people required to accommodate = 1/65 × 520

Find the average rate of change of
g(x)=-2x^3+5 from z=-4 to x=3
The average rate of change of the function from x == -4 to x = 3 is calculated as: -26.
How to Determine the Average Rate of Change of a Function?The formula for determining the average rate of change across a given interval of a function is expressed as:
Average rate of change = g(b) - g(a)/b - a.
Given the function, g(x) = -2x³ + 5 to find the average rate of change from x = -4 to x = 3, do the following:
a = -4
g(a) = g(-4) = -2(-4)³ + 5 = -2(-64) + 5 = 128 + 5 = 133
b = 3
g(b) = g(3) = -2(3)³ + 5 = -2(27) + 5 = -54 + 5 = -49
Substitute the values into g(b) - g(a)/b - a:
Average rate of change = (-49 - 133)/(3 - (-4))
Average rate of change = -182/7
Average rate of change = -26
Thus, the average rate of change of the function from x == -4 to x = 3 is calculated as: -26.

a cheetah that is running 90 feet per second is running 120 feet behind an antelope that is running 60 feet per second. How long does it take for the cheetah to run up to the antelope? PLS FINISH ASAP
Answer: 4 seconds
Step-by-step explanation:
c=cheetah. a=antelope
a=c+120
c/90=a/60
c/90=(c+120)/60
60*c/90=60*(c+120)/60
6*c/9=c+120
2c/3=c+120
(2c/3=c+120)*3 ==> multiply the equation by 3 to get rid of fractions
2c=3c+360
2c-3c=3c-3c+360
-c=360
c=-360 feet==> position of cheetah before catching up to the antelope. This means that the cheetah needs to travel 360 feet before reaching 0 ft when it catches the antelope.
360 feet * 1 second/90 feet=
