The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate

of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?

The average rate of change in h(t) between t = 1 second and t = 3 is:



(h(3) - h(1))/(3 - 1) = ((3 + 70*3 - 16*3^2) - (3 + 70*1 - 16*1^2))/2 = 6



The average rate of change in h(t) between t=1 and t=3 tells us that that average speed between these points is 6 ft/s.

Answer: Choice C

The probability of getting all heads is the same as the probability of getting all tails

=========================================================

Explanation:

H = heads

T = tails

In the first row, we have HHH to signify three heads. This shows up 1 time out of 8 outcomes total (each row is a different outcome). The probability of getting HHH is 1/8.

In the last row, TTT means we got three tails. Like with HHH, it only shows up once out of eight times, so the probability of getting TTT is 1/8 as well.

Therefore, both HHH and TTT have the same probability. This is because both sides of the coin have equal chances to land on. If the coin was more biased toward heads for example, then HHH and TTT would have different probabilities.

You are told to you will have to wait 5 hours in a line with a group of other people. Determine it. 1.You know the number of min
gulaghasi [49]

Answer:

for\ five\ hours = 300\ min

Step-by-step explanation:

Given:

Waiting time = 5 hours.

We need to find the number of minutes for 5 hours.

Solution:

We know that 60 minutes for each hour, so one hour is equal to 60 minutes.

For one hour = 60\ minutes

For five hours = 5\times 60

for\ five\ hours = 300\ min

Therefore, you will have to wait 300 minutes in a line.

THE DIFFERENCE OF TWO NUMBERS IS 4 AND THEIR SUM IS -7. WHAT IS THEIR PRODUCT. Who ever solved this correct will mark brainlist.
babunello [35]

Answer:

33/4

Step-by-step explanation:

Let the first number be x, and the second number be y.

x - y = 4

x + y = -7

Solve for x in the first equation.

x - y = 4

x = 4 + y

Put x as (4 + y) in the second equation and solve for y.

4 + y + y = -7

4 + 2y = -7

2y = -7 - 4

2y = -11

y = -11/2

Put y as -11/2 in the first equation and solve for x.

x - y = 4

x - (-11/2) = 4

x + 11/2 = 4

x = 4 - 11/2

x = -3/2

Their product is:

-11/2 × -3/2

33/4
