Answer:
At 7 seconds the instantaneous rate of change of the function s(t) with time which is the velocity is -11.18 m/s
Step-by-step explanation:
The given information on the height can be written as follows;
s(t) = -2.72·t² + 26.9·t + 6
Where;
s = The height (displacement) of the golf ball
t = The time taken during the motion of the golf ball
The velocity is found by finding the derivative of the displacement s as follows;
v = d(s(t))/dt = d(-2.72·t² + 26.9·t + 6)/dt = 2×(-2.72)×t + 26.9
When t = 7, v = 2×(-2.72)×7 + 26.9 = -11.18 m/s
Therefore the ball is coming down with 11.18 m/s speed at 7 seconds.

Answer:
$2988.37
Step-by-step explanation:
Subtract the payment from the previous balance. Convert the APR to a decimal. Multiply the unpaid balance by this decimal. Divide the product by 12 to calculate the interest added for this month. Add the new amount owed, the interest, and the new transaction to determine the new balance.
