Brantley tosses a ball out of a window that is 60 ft in the air. its initial velocity is 18 ft per second. the path of the ball is represented by
h = -16t^2+18t+60
how long does ot take for the ball to hit the ground (in seconds) rounded to the nearest hundredth?

  2.58 seconds

Step-by-step explanation:

When you complete the square, you get ...

  h = -16(t -9/16)^2 +60 +81/16

Then the solution for h=0 is ...

  t = (x -9/16)^2 = 1041/256

  t = (9 +√1041)/16 ≈ 2.57903 ≈ 2.58

It takes about 2.58 seconds for the ball to hit the ground.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
