Answer:
87.92in³
Step-by-step explanation:
Volume of cylinder formula:
Plug in the values using 3.14 for pi:
V = 3.14(2)^2(7)
V = 87.92in³
ANSWER
y varies inversely as x exponent 4.
EXPLANATION
The inverse variation equation is given as:
We can see that there is an inverse relation between the quantity y and x.
If the it were 
, we say y varies inversely as the square of x.
Hence for the given relation,the precise definition is that, y varies inversely as x exponent 4.
If the order matters it is a permutation. For example: if you are selecting 3 people to be on a committee it doesn't matter what order you select them, but if you're selecting three people to be president, vice president, and secretary the order in which you choose them matters the first person being president, the second person being vice president, and the third person be secretary
Set the height to h, and the width to w.
We know that wh=190 and h=2w-1.
Substituting 2w-1 for h, we have:
w(2w-1)=190
So:
2w^2-w-190=0
Factoring this equation, we get (2w+19)(w-10)=0. The solutions to this equation are -9.5 and 10, but clearly the width must be positive, Substituting 10 for the width, we get 10*2-1=19 for the height.
E is the answer to this question
