If you take the derivative of h(t) and solve dy/dx=0 for t, then you can use that value of t back in h(t) to find the maximum height that was reached.

Answer:

5820 square inches

Step-by-step explanation:

For the rectangular prism in the middle:

24*30=720*2=1140

10*30=300*2=600

1140+600=1740

For the left triangular prism:

10*24=240

26*30=780

24*30=720

10*30=300

240+780+720+300=2040

For the other right triangular prism, it's the same.

Let's add now to find the surface for the whole ramp.

1740+2040+2040=5820

Hope this is helpful to you

Answer:

$191

Step-by-step explanation:

Find how much she will be paying over the 24 months:

Add the down payment to this:

816 + 70

= 886

Find the difference between this and 695:

886 - 695

= 191

So, the difference will be $191 more
