Answer:
15%
Step-by-step explanation:
The price of the tablet was increased from $180 to $207.
Increase = $207 - $180
= $27
Therefore,
Percentage increase = increase/initial amount x 100%
That’s $27/$180 x 100%
0.15 x 100
15%
The percentage increase was 15%

Answer:
<em>3 seconds</em>
Step-by-step explanation:
Given the height modelled by the function
h(t) = -16t² + 16t + 96
The hit the water at h(t) = 0
0 = -16t² + 16t + 96
Divide through b y -16
0 = t² - t - 6
t² - t - 6 = 0
t² - 3t+2t - 6 = 0
t(t-3)+2(t-3) = 0
t+ 2 = 0 and t - 3 = 0
t = -2 secs and t = 3secs
Since t can't be negative, hence;
t = 3 secs
<em>hence it will take 3 seconds until Devon hit the water</em>
