You have to ask yourself the meaning of h(0)
That means that GS Hopper is at this starting position
h(0) = -0^2 + 4/3 * 0 + 1/4
GS is 1/4 of a unit above the ground. So you need to find out how to solve h(t) so that the value of h(t) = 0 There is a difference between h(t) = 0 and t = 0.

-t^2 + 4/3 t  + 1/4 = 0 I'd multiply through be 12. It might be easier to do.
-12 t^2 + 16t + 3 = 0 Remember all terms have to be multiplied by 12.
I know this seems laborious, but you should divide through by - 1
12t^1 - 16t - 3 = 0. That way you don't have to explain what to do with the minus 1. Negatives can be a real pain.

It does factor. 
(2x - 3)(6x + 1) = 0 This is just a guess that was lucky. You have to try combinations to get it right. Luckily 3 has only 1 and 3 as factors.
2x - 3 = 0
2x = 3
x = 3/2
x = 1.5 This answer means that 1.5 s starts his jump, he's on the ground.

the other root is meaningless. You can't have minus time in these questions.
Answer t = 1.5 s <<<< answer

Spotlight Dance increased the number of dancers on its competition team. Last
Nana76 [90]

Answer:

80%

Step-by-step explanation:

To find percentage increase, we use the following formula:

Percentage Increase = \frac{New-Old}{Old}*100

Here

New means the latest value (which is 18 dancers)

Old means the previous value (which is 10 dancers)

The Multiplication by 100 is to convert the decimal answer to percentage.

So, we have:

New = 18

Old = 10

Now we substitute and find:

\frac{New-Old}{Old}*100\\\frac{18-10}{10}*100\\\frac{8}{10}*100\\80

So, there was an increase of 80%

kati45 [8]
12000 = 2x - 1500
