the perimeter of a rectangle is equal to 2L + 2W.

the perimeter of the rectangle is represented by P.

P = 2L + 2W

when W is fixed at 8, the perimeter of the rectangle becomes P = 2L + 16

A)Write a formula that expresses the length of the rectangle in inches, l, in terms of the number of seconds t since the rectangle began growing.

time in seconds is represented by T.

the length of the rectangle increases by 2.4 inches every second.

L = 2.4 * T

B)Write a formula that expresses the perimeter of the rectangle in inches, P, in terms of the length of the rectangle in inches, l.

P = 2L + 16

C)Write a formula that expresses the perimeter of the rectangle in inches, P, in terms of the number of seconds t since the rectangle began growing.

P = 2 * 2.4 * T + 16 which becomes P = 4.8 * T + 16

D)Suppose the function g determines the perimeter of the rectangle in inches given a number of seconds t since the rectangle started growing. Write a function formula for g.

g(T) = 4.8 * T + 16

when T = 0, the perimeter of the rectangle is equal to 0 + 16 = 16.

when T = 1, the perimeter of the rectangle is equal to 4.8 + 16 = 20.8.

when T = 2, the perimeter of the rectangle is equal to 9.6 + 16 = 25.6.

etc...

keep in mind that the formula for the perimeter of the rectangleis P = 2 * L + 2 * W.

W is always 8, so the formula becomes P = 2 * L + 16.

L is equal to 2.4 * T, so the formula becomes P = 2 * 2.4 * T + 16.

after simplification, the formula becomes P = 2.8 * T + 16.

the complete question is

A rectangle has a fixed width of 8 inches and a length of 0 inches. The length of the rectangle then begins increasing at 2.4 inches per second.

A)Write a formula that expresses the length of the rectangle in inches, l, in terms of the number of seconds t since the rectangle began growing.

B)Write a formula that expresses the perimeter of the rectangle in inches, P, in terms of the length of the rectangle in inches, l.

C)Write a formula that expresses the perimeter of the rectangle in inches, P, in terms of the number of seconds t since the rectangle began growing.

D)Suppose the function g determines the perimeter of the rectangle in inches given a number of seconds t since the rectangle started growing. Write a function formula for g.

John made a rectangle pen for his dog using 28 feet of fencing. If the width of the pen is 2 feet more than one-half the length,
kati45 [8]
Okay, so you know that the perimeter of the pen is 28 feet. Now we need the separate side lengths.

P = 28 ft.
Length = x
Width = (1/2)x + 2

So now we can plug in the little equations of length and width into a perimeter formula:
 2(x) + 2((1/2)x + 2) = 28
Distribute the 2's and solve as needed.
2x + x + 4 = 28
3x + 4 = 28
3x = 24
x = 8

To find the width, just plug in 8 for x in our little equation:
(1/2)(8) + 2
= 6

So, the length is 8 feet and the width is 6 feet.

swat32
All our answers lie in the above statement.

Confidence Level:
The creator claims that 9 out 10 students will have the average score in the said range. Or in other words we can say that the creator is 90% confident about the result of the field test. So the confidence level is 90%. 

Margin of Error:
The average score lies within 4% of 70%. This means the margin of error is 4% i.e. the average scores can deviate from 70% by 4% .

Confidence Interval:
Lower Limit = 70% - 4% = 66%
Upper Limit = 70% + 4% = 74%

Interpretation:
The exam creator is 90% confident that the average scores of seniors will be between 66% and 74%.

Please help I don’t understand how to do this
lara [203]

Answer:

65 degrees

Step-by-step explanation:

All angles of a triangle have to add up to 180 degrees. After establishing that, we can see that there are two angles given. 25 degrees and a 90-degree symbol. So if two angles add up to 115 degrees, we can do 180-115=65 to find the angle of C.
