Answer:
144 feets
Step-by-step explanation:
Look on s(t) like quadratic function. We need to find maximum of the function using 1st diferetioal:
s(t)=-16t^2+64t+80
s’(t)=-32t+64
S’(t)=0 if t=2
For t>2, s’(t)<0
For t<2, s’(t)>0. So the maximum od function is in the point 2.
S(2)=-16*4+64*2+80=-64+128+80=144
The answer is D, hope this helped.
Answer:
There are 15 ounces left in the bucket.
Step-by-step explanation:
Starting with 30 ounces.
If Amy used 1/10 and Carl used 2/5 (4/10), we add that to get 5/10, or 1/2.
Half of 30 is 15, so there's your answer!
Hope this helped. :)
