Answer:
[1, 2.5]
Step-by-step explanation:
A rate of change on x- axis is defined as positive if the function increases as x does, and defined negative if y decreases as x increases.
Thus, we only need to see in which of those intervals [–2, –1] , [–1.5, 0], [0, 1]. [1, 2.5] the graph of the function goes only down if we look it from left to right.
The only one interval satisfying this condition is [1, 2.5].
Answer:
The balance after 15 year is $831.25 .
Step-by-step explanation:
Formula
Where P is the principle and r is the rate of interest in the decimal form and t is the time.
As given
Caiden earned $475 from mowing lawns last summer.
He deposited this money in an account that pays an interest rate of 3.8% compounded annually.
Here
P = $475
3.8% is written in the decimal form.
= 0.038
r = 0.038
t = 15 years
Put in the formula
Amount = $831.25
Therefore the balance after 15 year is $831.25 .
so after the 10 non soloists join, there would be 60 students total and 12 of them are soloists.
12 is 20% of 60
Final Answer:
20% of the choir are soloists.
Hope this helped!
Have an awesome day :)
Well, a y-intercept is a the point on a graph where the x value equals 0, because the point sits exactly on the y-axis. In this case, the y-intercept would be (0, -9).
