Answer:

The value of x is 15 inch.

Step-by-step explanation:

Area, A = 81 square inch

Perimeter, P = 48 inch

let the side is y.

y^2 = 81\\\\y = 9 inch

Let the other side is d.

P = 4 d = 48

d = 12 inch

the length x is given by

x^2 = 9^2 + 12^2\\\\x^2 =81 + 144 = 225\\\\x = 15 inch

So, x = 15 inch.

A college football stadium has a capacity of 100,000 people. The team is sponsoring a family day when tickets are $50 per person
Keith_Richards [23]

Answer:

I believe the variable N would be 100,000 because it is saying that tickets are $50 a person so you have to multiply that by how many people are at the stadium. So you would do 50(100,000) which equals 5,000,000.

Step-by-step explanation:

Explanation is in the answer above.

The average rate of change of the function: f(x)=4x^3-3x^2+2x-1 in the interval [0,3] will be
fomenos

Answer:

29

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ 0, 3 ], thus

f(b) = f(3) = 4(3)³ - 3(3)² + 2(3) - 1 = 108 - 27 + 6 - 1 = 86

f(a) = f(0) = - 1, thus

average rate of change = \frac{86-(-1)}{3-0} = \frac{87}{3} = 29

MatroZZZ [7]
Pentagon=5, there will be 5 triangles and one base. area of triangle=1/2bh
1/2(8)(16)*5=320. 320 is the area of all of the triangles on the side. Since we are looking for lateral area, we need not include the base. So, the lateral area is 320 square inches.
