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
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
We have:
c - the total number of cars,
d - the number of days;
c = f ( d ) = 100 d
Answer: C )
Well the answer would be
6x2 ( 2 is an exponent) -7
Answer:
14
Step-by-step explanation:
10 questions = 4 correct + 6 incorrect
4 correct = 4* 5 = 20
6 incorrect = 6* (-1) = -6
His score is 20 -6 = 14 points
