the length of a city block
a and b represent the slopes in the equations. Use the y-mx+b formula to realize this. M is the slope, a or b in this question. The lines both have positive slopes so B or C cannot be the answer. I cant see the image properly, but if the y int is at 0 then A is the answer, but if it is above 0 then D will be your answer.
Answer: C 4/3(4.32x10^15)
Explanation:
Volume of sphere is 4/3
r^3
(4.32x10^5)^3= 4.32x10^15
4/3(4.32x10^15)
