Devin jumped off a cliff into the ocean in Acapulco while vacationing with his family. His height as a function of time could be

modeled by the function h(t)= -16t square root 2 +16t +96, where T is the time in seconds and H is the time in feet. How many seconds until Devon hit the water? Around to the nearest tenth is necessary.

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>

igomit [66]
The appropriate response is B. The contend that there is no requirement for understudies to utilize a compass and straightedge, and every single geometric development ought to be finished utilizing a drawing program is the wrong explanation since the power to control drawing programs is just open in a few spots. Not everyone would have the capacity to learn geometry in light of the fact that not everyone can have power. Everyone on the planet would not have a similar opportunity to learn geometry if just drawing programs had the information that we have today.
