An equation to solve for the time when the high school will have exactly 100 students is (1-.06)^x = (250/100).
That simplifies to 94^x = .4.
We can then take the log of both sides to isolate the x variable from the exponent. Here's with natural log.
x*ln(.94)=ln(.4)
x = ln(.4)/ln(.94)
Solving this gives x ~= 14.80. So in about 15 years, the high school will have 100 students.
Here we go ~
The equivalent expression will be ~
Answer:
No
Step-by-step explanation:
y=0.375x is a proportional or linear relationship because y is a consant multiplied by the variable x. In other words, x increases with y at a linear rate, therefore being proportional.
