Answer:
The Volume of cylinder is: 
Option B is correct option.
Step-by-step explanation:
We are given:
Volume of cylinder = h = 2x+7
Radius of cylinder = r = x-3
We need to find volume of cylinder
The formula used is: 
Putting values and finding volume

So, The Volume of cylinder is: 
Option B is correct option.
Sample space of S{A, B, C, F, G, M, T, Z}, subset A{A, G, M}, subset B{A, B, F, G, T, Z). Determine AUB.

AUB means combination of elements in A and B without writing one element twice
AUB={A,B,F,G,M,T,Z}
Part A. Lest fin the zeros of our function first:
Step 1. Set the right side of the function equal to 0:

Step 2. Multiply both sides of the equation by -1

Step 3. Factor the left side:
Step 4. Set each factor equal to 0 and solve for

:

and


and

Since distances can't be negative, the zero of our function is

.
<span>We can conclude that the zero </span>
represents that when the horizontal distance of the diver is 3 ft, he is is in the surface of the pool. In other words, his vertical distance is zero.
Part B. To factor our quadratic equation

, we are going to use the method for simple cases because

:
Step 1. Find tow numbers whose product is

and its sum is

:
We know form our quadratic that

,

, and

, so

.
We want tow numbers that multiply together to make -18, and add up to 3.
Those number are 6 and -3.

and
Step 2. Rewrite the middle term

using those numbers:
Step 3. Factor the expression:
