Answer:
v(t) = 6t^2 +5
Step-by-step explanation:
Velocity is the derivative of position. The derivative of a sum is the sum of the derivatives of its terms. The power rule for derivatives is ...
(d/dx)(x^n) = n·x^(n-1)
So, the derivative of d(t) is ...
v(t) = 2(3t^2) +5(1t^0)
v(t) = 6t^2 +5 . . . . matches choice C

Answer:
10 sculptures
Step-by-step explanation:
He makes 1 sculpture for every 5 paintings. We can break it down like this to simplify:
We know that if he made 50 paintings in total, thats 10 groups of five paintings (5x10=50)
For every group of 5 paintings, he makes one sculpture
So if there are 10 groups of five paintings, he made 10 sculptures.
