Whose stone hit the water first? (options lins stone, clares stone) When did that happen? (options 1/2 second after stone was to
slega [8]

Answer:

1) Clare's stone hit first.

2) 1 seconds.

3) Same maximum height for both.

4)  9 feet

Part A:

h = (-16t -8)(t - 1)

When the stone hits the water, the height will be 0

⇒ (-16t - 8)(t - 1) = 0

<u>set to zero</u>

⇒ -16t - 8 = 0, t - 1 = 0

<u>simplify</u>

⇒ t = -1/2, t = 1

So, time was 1 seconds for Clare and 1.25 seconds or Lin. Clare's hit first.

Part B:

For Lin's stone: maximum height: 9 feet.

For Clare stone: (-16(0.25) - 8)((0.25) - 1) = 9 feet

No both stone reached the maximum height of 9 feet.

Evaluate the following expression when t= 2 .<br> t² – 44 - 4<br> Help please
valentina_108 [34]

Answer:

-44

Step-by-step explanation:

So you want to plug 2 in for t, so the equation should now look like:

2^{2} - 44 - 4

No all you have to do is solve

2^{2} = 4

4 - 44 = -40

-40 - 4 = -44
