Answer:10 to the power of 8
Step-by-step explanation:since 10 is used as a factor 8 times, the exponent is 10 to the power of 8.
Answer:
4.) 40 Apps can be downloaded in 1 minute
5.) 0.2 or 2/10 of a miles can be traveled in 1 second
Step-by-step explanation:
4.)
So 12 seconds is = to 1/5 of a minute
So the question asks for 1 minute
This means that we need to perform 1/5 *5 to get 1 minute
If we multiply 5 to 1/5 minutes, we also need to multiply 5 to the apps
8 * 5 = 40
So that is how we solved the answer.
So DeAndre can download 40 Apps in 1 minute.
5.)
So he traveled 1/10 miles in 1/2 or 0.5 seconds.
This means we can multiply the seconds by 2 to get 1 second.
0.5 * 2 = 1
If we multiply the seconds by 2 we also need to multiply the miles traveled by 2.
So (1/10) * 2
The 2 can be rewritten as (2/1) because 2/1 is the same as 2
(2/1) * (1/10)
So we multiply straight out and get 2/10 miles traveled which can be simplified to 1/5 miles traveled.
Answer:
The average rate of change = 4.
Step-by-step explanation:
Here we have formula.
Average rate of change = f(b) - f(a)
-----------
b - a
Given: f(X) = x^2 + 5x - 12 interval [-2, 1]
Here a = -2 and b = 1
f(a) = f(-2) = (-2)^2 + 5(-2) -12
= 4 -10 -12
f(-2) = -18
f(b) = f(1) = (1)^2 + 5(1) - 12
= 1 + 5 -12
f(1) = 6 -12
f(1) = -6
Now apply these values in the above formula, we get
Average rate of change = [-6 - (-18)] / [1 -(-2)]
= [ -6 +18]/1 +2
= 12/3
= 4.
Therefore, the average rate of change = 4.
Hope this will helpful.
Thank you.
