The position of an object at time t is given by s(t) = 1 - 10t. find the instantaneous velocity at t = 10 by finding the derivative. show work

Step-by-step explanation:

The position function is .

The instantaneous velocity at t=10 is given by:

.

We first of all find the derivative of the position function to get:

We now substitute t=10 to get:

Therefore the instantaneous velocity at t=10 is -10m/s

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
