A)
8^2+9^2=c^264+81=c^2
c^2=145c=sqrt 145c=12.04
B)
Pythagerean Theorum: 
A^2+B^2=C^2, where C is the hypotenuse and A and B are the other legs 
15^2=9^2+B^2 
225=81+B^2 
225-81=B^2 
144=B^2 (square root both sides) 
12=B

tekilochka [14]
Archy:  15 gallons ... $23.85
               1 gallon ...$ x = ?

x * 15 = 1 * 23.85    /15
x = 23.85 / 15
x = $1.59 per gallon

Joe:  16 gallons ... $24.48
           1 gallon ... $ y = ?

y * 16 = 1 * 24.48    /16
y = 24.48 / 16
y = $1.53 per gallon

Result: Joe paid less per gallon.

Multiple Choice: A prism and a pyramid have identical bases and heights. The volume of the prism is: Twice as large as the pyram
Natali [406]

Answer:

<h3>Three times as large as the pyramid's volume</h3>

Step-by-step explanation:

Let the volume of prism be Vp

Let the Volume of pyramid be Vy

Vp = Base Area * Height .... 1

Vy = Base * Height/3 ....2

From 2;

Vp = BH/3

BH = 3Vy

Since Vp = BH, then;

Vp = 3Vy

This shows that the volume of prism is three times as large as pyramids volume

2x +2y=24

2x-24=-2y

divide by then u get:

-1x + 12= y

-1 is ur slope

Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.
hichkok12 [17]

Answer:

2\pi(e^2-e^{-4})

Step-by-step explanation:

We are given: f(x)=2e^x

So, the integral will be used to calculate the volume.

V = \pi\int\limits^1_{-2}(2e^x)^2dx=\pi\int\limits^1_{-2}4e^{2x}dx=2\pi e^{2x}|^1_{-2} =2\pi(e^2-e^{-4})
