larger box: 8*3*5 = 120

here we see that one side of the smaller box is unlabeled. but the total side length is 7, and the larger box is 3 long, so:

smaller box= (7-3)*3*5 = 60

total=120+60=180

A ball is shot straight up from the top of a 15-story building. The motion of the ball could be described by the function: h(t)=
viktelen [127]

Answer:

  • After 4 seconds the height is 480 meters.
  • The maximum height is 484 meters.
  • The ball hits the ground after 10 seconds

Step-by-step explanation:

The height after four seconds is h(4) = -16 * r² + 144*4+160 = 480

The maximum height of the ball is the value it takes at its vertex 'v = -b/2a'. In this case a = -16 and b = 144, so the v = -144/-32 = 4.5. The maximum height of the ball as a result is h(4.5) = -16 (4.5)² + 144*4.5 + 160 = 484

To find the moment the ball hits the ground, we need to find when h takes the value 0 by using the quadratic formula, with a = -16, b = 144 and c = 160.

r_1,r_2 = \frac{-144 \, ^+_- \sqrt{144^2-4*(-16)*160}}{2*(-16)} = \frac{-144 \, ^+_- \sqrt{30976}}{-32} = \frac{-144 \, ^+_- 176}{-32} = -1, 10

Since t cant take negative values, then the correct value is 10. The ball hits the ground after 10 seconds.

Use complete sentences to describe the steps involved in solving x2 − 64 = 0 two different ways.
muminat

Answer:

1. First, add 64 to bith sides, cancelling one out and taking it to the other side, then dividing by two, giving you x=32.

2. Subtract 2x and take it to the other sude of the equation. Then divide -2 by -64, giving you x=32, due to the negative cancelling (turning to a positive).
