Answer:

4.4 m

Step-by-step explanation:

Draw the height of the triangle (perpendicular line from point A to line BC).  Since ABC is an isosceles triangle, the height is a perpendicular bisector, so it splits the triangle into two congruent right triangles.

Use Pythagorean theorem to find the height.

c² = a² + b²

(8.5 m)² = (14.5/2 m)² + h²

h ≈ 4.4 m

Devin jumped off a cliff into the ocean in Acapulco while vacationing with his family. His height as a function of time could be
sukhopar [10]

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>

oee [108]
Rule of 72 says to divide 72 by the rate of return and that will be the number of years an investment will double
 so 72 / 9.6 = 7.5 years to double

7.5 * 2 = 15 years

18-3 = 15

 the answer is: <span>Yes, the $15,000 will double each 7.5 years. In 15 years, it will double twice.</span>
