D = 10 is the diameter so r = d/2 = 10/2 = 5 is the radius

Plug r = 5 and h = 7 into the formula below and simplify
V = pi*r^2*h
V = pi*5^2*7
V = pi*25*7
V = pi*175
V = 175pi

PLEASE HELP I WILL GIVE BRAINLIEST MUST USE WORK :)

Nikolay [14]

slope = (y2-y1)/(x2-x1)

m =(-2-7)/(8-0)

m =(-9/8)

slope is -9/8

the y intercept is 7 (0,7)

y = mx +b

y = -9/8 x+7

Answer: y = -9/8x +7

What is the value of c so that -12 and 12 are both solutions of x^2-c=108?

murzikaleks [220]

Answer:

c=36

Step-by-step explanation:

Because $x^2-c=108$ can be rewritten as $x^2-c-108=0$ , finding the value of c so that x=(+-)12 solves this equation it means to find the value of c so that $(+-)12^2-c-108=0$ .
Because $12^2=(-12)^2=144$ , we must find c so that $144-c-108=0$ .
Because $144-108=36$ , c=36.
To check, replace c=36 in the initial equation, and check it is a solution for x=(+-)12.
