Answer:
#1 is 9 times 10^15
#2 is 3 times 10^8
Step-by-step explanation:
Answer:
The relationship is proportional.
The relationship is linear.
The equation of the line is y = –3x.
Step-by-step explanation:
The line in the question passes through origin and (4,-12).
The rate of change of the line is

The rate of change of the line or slope of the line is -3
Equation of the line is given by

This means that the relationship is linear.
If we take any value of x then there will be only one value of y this means that the relationship is proportional.
So the following statements are true
The relationship is proportional.
The relationship is linear.
The equation of the line is y = –3x.
I'm guessing here, but I may be right. The answer is x=0
If I'm wrong please correct me!!
It is indeed 70, you divid 63 by 90 and your answer should be .07 so if you add that to your starting 63 you get 70
R = 6 in;
60° = 1/6 · 360°
The area of the slice of pie:
A = 1/6 · r² · π
A = 1/6 · 6² · 3.14 = 18.84 in²
