Answer:
B 480 in.³
Step-by-step explanation:
Volume of a rectangular prism is given by
V = l*w*h
V = 8*12*5
V =480 in ^3
One form of the equation of a vertical parabola is y = x^2, which is the same as y-0 = a(x-0)^2.
If the coefficient a is positive, the parabola opens up. If a is - the parabola opens down.
The vertex of this parabola is (0,0).
More generally, y - k = a(x - h)^2 represents a vertical parabola that opens up if a is + and opens down if a is - and has its vertex at (h,k).
Often a = 1. If a is greater than 1, the graph of the parabola is stretched vertically; if less than 1, the graph is compressed vertically (and thus appears to be flatter).
y - k = a(x - h)^2 is called the 'general vertex form' of a vertical parabola.
This is a quadratic equation. With some algebra, we could rewrite
y - k = a(x - h)^2 in the form y = ax^2 + bx + c.
x-intercepts of this parabola, if any, can be found using the quadratic formula, involving the constant coefficients a, b and c.
Answer: 
Step-by-step explanation:
First, we separated the variables:
We integrate:
We change the variable for make more easy the integral:
Now replace with 
and evaluate the limit:
Using properties of natural logarithm
Taking exponential of both sides
