20 to 25 percent change
inna [77]
A change from 20 to 25 represents a positive change (increase) of 25% Percent change = [(20 - 25) / 20] x 100 = 25 % (increase)Where: 20 is the old value and 25 is the new value. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old value.

Hope this helps :)

Could someone help me with this?
hodyreva [135]

Step-by-step explanation:

Identity the variable:

Initial Velocity is 35.

Initial Height is 204

Final Height is 0.

What looking for the time.

So we have

0 =  - 16 {t}^{2}  + (35)t + 204

Use Quadratic Formula,

- b± \frac{ \sqrt{b {}^{2}  - 4ac} }{2a}

A is -16, B is 35 , C is 204.

So we have

- 35± \frac{ \sqrt{ {35}^{2} - 4( - 16)(204) } }{ - 32}

- 35± \frac{ \sqrt{1225 + 2240}  }{ - 32}

- 35± \frac{ \sqrt{3465} }{ - 32}

{35}  ± \frac{ \sqrt{3465} }{ - 32}

The positve solution is

4.83

So the answer is 4.83 seconds
