Answer:

9.7 seconds to the nearest tenth.

Step-by-step explanation:

He falls for a distance of 1,500 ft.

We use the equation of motion  s = 1/2 * 32 * t^2   where s = distance and t = time.

1500 = 16 * t^2

t^2  = 93.75

t =  9.7 seconds answer.

Answer:

9.7

Step-by-step explanation:

minus 1,000 ft (the height he opened his parachute) from 2,500 (the height of which he started)

This will give you the distance of his fall

1,500 ft.

Then, use the equation of motion which is s = 1/2 * 32 * t^2  

where s represents distance and t is time

1500 = 16 * t^2

t^2  = 93.75

Then simply round to the nearest tenth and it will be on the test :)

I really just ignored the equation it gives to solve it sorry.

Find the solution set of the inequality<br> 12 - 6x &gt; 24.
Hoochie [10]

Answer:

x < -2

Step-by-step explanation:

12 - 6x > 24       Equation

-6x > 12        Subtract 12 from both sides

x < -2        Divide both sides from -2, if you divide by any negative number in an inequality you have to switch the sign
