Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (2, - 7)
m =
=
= 
Answer:
answer is number 3 you can check on a calculator
Step-by-step explanation:
The absolute value of a number is the distance away from zero that number is. The absolute value "gets rid" of the negative sign

15 is the answer
<span>Generate a function for the height of the cyliner as a function of radius. Use this function to generate a function of r for the material used. Take the derivative of that function, set it to zero, and solve for r.
