Answer:

160ms^{-1}

Step-by-step explanation:

d(t)=16t^2\\

To work out rate of change of a function, you must differentiate it.

\frac{\Delta d(t)}{\Delta t} =32t

d'(8)-d'(3)=32*8 - 32*3=32*5=160ms^{-1}

Tom used 5/8 yard of ribbon to tie weights on the tail of his kite. He cut the length of ribbon in equal pieces that were 1/12 y
sweet [91]
Here is the solution for the given problem above:
Given: 5/8 yard of ribbon = total length of the ribbon
            1/12 yard = length of the ribbon after Tom cut it equally
            ? = number of pieces of 1/12 yard from 5/8 yard
So to divide fractions, here is the solution
5/8 divided by 1/12
5/8 multiplied by 12/1
5x12 is 60
8x1 is 8.
So 60/8 would be 7.5. Therefore, the number of pieces that was cut from the 5/8 ribbon is 7.5. Hope this answer helps.
