Answer:
f(-5) = 15
Step-by-step explanation:
f(x)=5x+40
plug in x as -5
f(-5) = 5(-5) + 40
multiply 5 by -5
-25+40
add -25 to 40
15
4.5 x 6.2 = 27.9

Answer:
a right cylinder with a radius of 7 inches
y = -2/3x -3
x=0 y=-3 point (0,-3) over 0 down 3
x=3 y=-2/3(3) -3 =-2-3 =-5 (3,-5) go to the right 3 down 5
Max occurs at x=50 where F'(x) = 0.
We need to find value for F(50) using fundamental theorem of calculus:


Where A is the estimated Area under the graph.
If we assume the shaded region is close to a right triangle then the Area is (1/2)*30*20 = 300
Therefore
