Answer:
Point (2, 20) does not lie on the given curve.
Step-by-step explanation:
Let us see explanation:
(2, 20) is not on the curve.
When x = 3, f(x) = 2*5^3 = 250 . So (3, 250) is on the curve.
When x = 1, f(x) = 2*5^1 = 10 . So (1, 10) is on the curve.
When x = 2, f(x) = 2*5^2 = 50 . So (2, 50) is on the curve.
From the last line we see that (2, 20) is NOT on the curve.
the common difference is plus 3
D 12.57
diameter = 4inches hence radius = 2inches
if the crust covers the full pizza "around", technically its the circumfrence
hence 2πr
2×π×2= 12.566 ~ 12.57
d is the correct ans
see,
As the bases are equal we can cut the bas,
