Answer: B
Step-by-step explanation:
The equation 
is not yet in slope-intercept form(
). Simply subtract 2 from both sides to turn the equation into slope intercept form as 
. For a line to be perpendicular to another, it must have an opposite reciprocal slope. A reciprocal is the fraction reversed, where the numerator is the denominator and vice versa. Thus, 3/4 would become 4/3. The opposite reciprocal of 3/4 would be -4/3.
The slope of the line given is 3/4. Thus, simply plug in the opposite reciprocal of 3/4 for the slope to get: 
. Then, because the line passes through -12, 1, plug those values in for x and y, respectively.
Thus, the equation of the line is 
, or B.

Answer:
V = pi*x^2*(18x - 45)
Step-by-step explanation:
If the diameter is 6x and the height is 2x + 5, we know that the radius is 3x.
Plugging this info into the volume-of-a-cylinder formula V = pi*r^2*h, we get:
V = pi*(3x)^2*(2x - 5), or V = pi*(9x^2)(2x -5), or:
V = pi*(18x^3 - 45x^2), or V = pi*x^2*(18x - 45)
3/4 * 100
3*100= 300
300/4= 75 %
