A penny is dropped from the top of a 1,000-foot building. the function gives the height of the penny t seconds after it starts f
2 answers:
We consider an approximation of the gravity g=10.
Then the speed is given by the formula: s(t)=10t.
And the coordinate is given by the formula:x(t)=5t^2+t
(integrating the speed function).
Now set up the equation:
Solving the above equation for t we get:t =14 seconds.
<span>It will take 14 seconds for the penny to reach the ground.</span>

Answer:
Step-by-step explanation:
f(x) = 70 + 11x
To find the value of x when f(x) =158 , equate f(x) to 158
We have
Divide both sides by 11
We have the final answer as
<h3>x = 8</h3>Hope this helps you
