I need to know the seconds
laiz [17]

Answer:

t = 3 seconds

Step-by-step explanation:

Here h(t) = -16t^2 + 144.  

When the quarter hits the ground, its height will be 0 feet.  Letting h(t) = 0 results in     -16t^2 + 144 = 0, or 16t^2 = 144, or

          144

t^2 = ------------ = 36/4 = 9 seconds^2

             16

Therefore, the time, t, required for the quarter to hit the ground is t = √9, or t = 3 seconds

PLEASE HELP ASAP! EXPLAIN THE ANSWER!
Stells [14]

Answer:

<h3>1863 m squared</h3>

Step-by-step explanation:

So, the goal here is to find the area of each block individually then add it all together. In other words, you're gonna look for a way to solve for the missing square in the total large rectangle. Keep in mind 23 + 23 + 23 = 69 (aka the length of the whole rectangle)

So:

12 x 23 = the missing square = 276

31 x 69 = rectangle with the square = 2139

Total area = 2139 - 276 = 1863
