Its A, the solution is the point where the two lines intercept
Since V = (4/3) * pi * R^3
If R is halved, V' will reduce by a ratio of (1/2)^3 = 1/8
So V' = (1/8)V
37.5 = initial rate
44.9 = slope/rate
In problems like these, just use y = initial rate + rate(variable)
In this case, the answer would be y = 37.5 + 44.9h
Answer:
well bcs we cool so appreciated <3 periodTH lolz
Step-by-step explanation:
The answer is option c.
That is, the wrong step in step 6. It was written that the center of the circunference is the point (2.1). However, the general equation of a circumference is:
(X- (a)) ^ 2 + (Y- (b)) ^ 2 = r ^ 2
Where the point (a, b) is the center of the circle.
So for this case the point for the center is: (-2, -1)
