How to do number 13 and 14
Murrr4er [49]

From the information: v is 64 while c is 5

Differentiate the new equation h=-16t^{2} + 64t + 5 to get \frac{dh}{dt}= -32t + 64.

no 13). At maximum height this derivative equals zero so: -32t + 64 = 0;  -32t = -64; t=2.Hence ans is 2 secs

no 14). put t as 2 sec in the equation: h=-16t^{2} + 64t + 5.  This gives

h=-16( 2^{2}) + 64(2) + 5; h=-64+128+5=69. Hence h is 69ft

Given f ( x ) = 1 x + 10 , find the average rate of change of f ( x ) on the interval [ 8 , 8 + h ] . Your answer will be an exp
son4ous [18]

Answer: 1

Step-by-step explanation:

f(8+h)=8+h+10=18+h\\\\f(8)=8+10=18

So, the average rate of change is:

\frac{(18+h)-18}{(8+h)-8}=\frac{h}{h}=\boxed{1}

The question is wrong, the expression will not be in terms of h since it is a linear function.
