1.
Height h = 240 feet
We insert it into formula.
240 = -16 t^{2} +128t
Now we solve this for t:
16 t^{2} -128t +240 = 0 /16  \\  t^{2}  - 8t +15 =0 \\ t_{1} = 5 t_{2} = 3

We have two answers as the rocket will pass this height on it's way up and down.

2.
Height h = 0 feet
We insert it into formula.
0=-16 t^{2} +76t + 2
Now we solve this for t:
16 t^{2} - 76t -2 = 0 /2 \\ 8t^{2} - 38t - 1 = 0 \\ t_{1} = 5 t_{2} = -1
We do not consider solution -1 as the time can not be negative. Our solution is 5s.

3.
Height at bottom of hill h = 0 feet
We insert it into formula.
v^{2} = 64 * 0 = 0 ft/s

What is the twentieth term of the arithmetic sequence described by the<br> equation an= 3n - 10?
sergij07 [2.7K]

Answer:

The twentieth term is 50.

Step-by-step explanation:

The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:

a1 = 3*1 - 10

a1 = -7

Therefore to find the twentieth term we need to make n equal to 20. This is done below:

a20 = 3*20 - 10

a20 = 60 - 10

a20 = 50

The twentieth term is 50.

Will mark Brainliest to whoever gets this right<br><br> What is the slope of this line?
Anestetic [448]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷  y = mx + c

Substitute in values using a point on the given line

7 = m(4) + 6

-6 from both sides

1 = m4

Divide both sides by 4:

m = 1/4

The slope is 1/4
