What does h(3.2) represent?
marshall27 [118]

Answer:

the height of the rock 3.2 seconds after it is propelled

Step-by-step explanation:

<u><em>The complete question is</em></u>

The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot

Let

t------> the time in seconds

h----> the the height of a rock after it is propelled by a slingshot in meters

we know that

h(t)=-16t^{2} +28t+500

For x=3.2\ sec

Find the value of h(t)

h(3.2)=-16(3.2)^{2} +28(3.2)+500=425.76\ meters

therefore

h(3.2) represent the height of the rock 3.2 seconds after it is propelled

see the attached figure to better understand the problem

Find the perimeter of the figure shown to the right.
tia_tia [17]

Step-by-step explanation:

that is very simple. you do understand the word "perimeter" ? it just means the distance when walking around the whole shape once.

and that clearly means to just add all side lengths.

that's it.

so, 25 + 18 + 18 + 20 + 17 = 98 ft

was there any other problem with this you did not understand ?
