Answer:

Step-by-step explanation:

Part a: Option D 18 feet per second
Part b: increasing
Solution:
Height 
Part a: To find the average rate of change for h(t) between t = 0 and t = 2.
Substitute t = 0 in h(t).

h(0) = 3
Substitute t = 2 in h(t).
h(2) = 39
Average rate of change formula:

Here, a = 0 and b = 2.



= 18
Average rate of change = 18 feet per second
Option D is the correct answer.
Part b:
This means height of the ball is increasing for 0 < x < 2.
Answer:
20.00
Explanation:
You can see that with every two coffees the amount is decreasing by 3.50 each time
The slope is -1.75 which is for every one coffee so this multiplied by 2 = 3.50
Answer:
a) 21
b) 78.5 - 28.3 - 12.57 = 37.63
Step-by-step explanation:
For the triangle, you want to use the formula 1/2 base times height and then subtract 2 time 2. For the circle, the formula is pi times the radius squared. Then, subtract the other circles using the same formula. I hope this helps! Please mark me brainliest because I have been scammed many times. Please and thank you.
In Canada in 1998 the estimated number of households written in standard decimal notation is 3939000
<u>Solution:</u>
Given that in 1998 estimated number of households that owned 2 or more vehicles was 
Need to represent the number
in standard decimal notation.
In this case we need to move the decimal point based on the power of 10.
In our case power of 10 = 6.
Let’s first take a number without
and add six zeros on right.
So we get 3.939000000
Now multiplying above number by
means moving the decimal after 6 numbers from the current position, that means

That is 3939000 is required standard decimal notation of scientific notation number
