Answer:
Step-by-step explanation:
d(t)=-2t^2+9t+18
calculate the derivate : f'(t) = - 4t+9
f'(t) = 0 : - 4t+9= 0 so t = 9/4
the maximum value is f(9/4) = ....... continue

Answer:
1,300
Step-by-step explanation:
First, we need to substitute all the variable with the given number.
To figure out the 2 equivalent squares, do 20 x 20 , which is 400.
Then, the 3rd triangle, do 28 x 25 , equaling 700.
Lastly, for the 2 triangles, 20 x 20 / 2 , leading to the solution of 200.
Now, putting everything together by adding 400+700+200, the final answer is 1,300.
I hope this helped!!
