Neglecting air resistance, the distance h(t) in feet traveled by a freely falling object is given by the function , where t is time in seconds. The height of a certain tower is 912 feet. How long would it take an object to fall to the ground from the top of the building? Round to nearest 0.1 second

t = 7.54 seconds

Step-by-step explanation:

The distance h(t) in feet traveled by a freely falling object is given by the function :

The height of a tower is 912 feet.

It is required to find the time it will taken to fall on ground from the top of the building. It can be calculated as :

So it will taken 7.54 seconds to fall on the ground.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
