7 and -4
Coefficients are the numbers before a variable, meaning that 7 and -4 (be careful of that subtraction sign) are the coefficients. Additionally if you were asked what the leading coefficient was the answer would be 7 because it has the greatest exponent attached to it (2).
Answer: 1.106 s
Step-by-step explanation:
This situation is related to projectile motion and one the equation that models the height of the blueberry pie in time is:

Where:
is the blueberry pie final height (when it hits the ground)
is the blueberry pie initial height
is the blueberry pie initial velocity
is the angle, assuming the pie was shot horizontally
is the time
is the acceleration due gravity
Rewriting the equation:

Answer:
6 inches
Step-by-step explanation:
Formula for surface area of a cylinder:

Plug in values and solve for the radius:

Divide both sides by 

Subtract 90 from both sides

Use the quadratic equation to find the roots
±

and 
and
We can't have a negative radius, so that leaves us with r=6 in.
