The 2 is in the tenths place so it is two-tenths.
Two-tenths = 2/10= .2
I hope that answers your question.
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>
The Absolute value bars act as the P in PEMDAZ (The P = Parenthesis but it really just means any containing symbols ( (), {}, [], || ) so you distrubute -2 into the bars resulting in the numbers becoming negative then you follow the steps down :)
