Mathematics
1 answer:
Sliva [168]3 years ago
6 0

Answer:

2 seconds

Step-by-step explanation:

This means the height, and thus h(t), is equal to zero.

0=-16t^2 + 16t + 32

0= t^2 - t - 2 (divide both sides by -16)

0 = (t-2)(t+1) [factor]

t = -1, 2 [set each factor equal to zero]

But as time cannot negative, take t=2, giving us 2 seconds.

How to solve this <br>3 = (2x + 8)/3​
seropon [69]

Answer:

x = 1/2

Step-by-step explanation:

First you want to get rid of the fraction, so you can multiply both sides of the equation by 3.

9 = 2x + 8

Then, subtract 8 from both sides to get x by itself.

1 = 2x

Finally, divide both sides by 2 so you only have one x

1/2 = x

This means that the answer is x = 1/2.
