The time it takes between when the rock was dropped and when it landed is 1.33 seconds.
<h3>What is the time it takes for the rock to land?</h3>
The time it takes the rock to land on the ground from where it is dropped can be determined by using the function given.
The height of the function when it hits the ground will be zero, so the function can be written as:


64 = 36t²

t² =1.778

t = 1.333 seconds

Explanation: If you try A, B, and C, you’ll find they are all correct, however D seems to be false.
Using trigonometric ratios, the measure of side n to one decimal is 6.6 units.
<h3>How to solve for a side using trigonometric ratios?</h3>
Using the trigonometric principle
SOHCAHTOA,
cos 20 = adjacent / hypotenuse
adjacent side = n
hypotenuse side = 7
Therefore,
cos 20° = n / 7
cross multiply
n = 7 cos 20°
n = 7 × 0.93969262078
n = 6.5778483455
n = 6.6 units
