Answer:

f(x) = -4x + 80

Step-by-step explanation:

You are given two points,

(5, 60) and (10, 40)

in order to get the equation, let's use the form slope-intercept form

m = (y1 - y2) / (x1 - x2)

m = (60 - 40) / (5 - 10)

m = 20/-5

m = -4

Get the x intercept

y = mx + b

60 = (-4)(5) + b

b = 60+20

b = 80

so the equation is

y = -4x + 80

f(x) = -4x + 80

the radius of the base is 4 inches and its height is 6 inches what is the surface area of the cylinder in terms of pi
wolverine [178]
Answer is 80pi
Step by step

To find lateral_area = (2 * π * r) * h

Since it’s in term of pi,
(2 x radius x height) pi
2 x 4 x 6 = 48pi

base_area = 2 * π * r²
Since it’s in terms of pi
(2 x r^2)
(2 x 4^2)
= 32pi

Total surface area in terms of pi = 32+48
= 80pi
