Answer: A toad population is increasing by about 7.5% each year.
An event organizer finds each year's attendance for the past five years is about 4/5 of the previous year's attendance.
Step-by-step explanation:
On the highway, Kareem's car gets 38 mpg.
This can be modeled with a linear relationship between the miles and the gallons of fuel needed.
Shu Fang has $25.75 deducted from her checking account every month.
Here we know that each month a constant amount is deducted from her, this is not an exponential relation.
A toad population is increasing by about 7.5% each year.
If the population initially was an amount P, after one year the population is P*1.075, after two years the population is P*(1.075)^2 and so on, this can be modeled with an exponential function where the years variable, the function will have the general form:
Population(y) = P*(1.075)^y
An event organizer finds each year's attendance for the past five years is about 4/5 of the previous year's attendance.
If the first year the population is X, the year after the attendance will be (4/5)X, and the year after this process applies again, so you have a 4/5 of the previous attendance, the attendance now is (4/5)^2*X
This also can be modeled with an exponential function, of the shape:
Attendance (y) = X*(4/5)^y, where again, y means years.
The thing you may notice is that in this case the model only works for the lapse of 5 years that the event organizer said.

Step-by-step explanation:
B. Adam ct. is parallel to Edward La.
C. Bertha Dr. is parallel to Charles st.
D. Dana la. is perpendicular to Charles st.
Answer:
A. Adam ct. is perpendicular to Edward Rd.
Step-by-step explanation:
We are given that,
Adam Ct. is perpendicular to Charles St.
Charles St. is parallel to Edward Rd.
So, we get the situation shown below.
It is required to find the relation between Adam Ct. and Edward Rd.
As, we can see that,
Charles St. being parallel to Edward Rd. and Adam Ct. being perpendicular to Charles St.
We get,
Adam Ct. is perpendicular to Edward Rd.
Hence, option A is correct.
The correct answer is:
True.
Explanation:
The definition of a minimum in a function is the point whose y-coordinate is less than every other y-coordinate in the function.
This is because the y-coordinate tells us how far up or down from the x-axis a point lies. If it is a minimum point, this means there is no point below it; there is no point with a smaller y-value.
Answer:
true
Step-by-step explanation:
The minimum value of a function is the place where the graph has a vertex at its lowest point.
The height of a point is given by its y value, then the minimum value is the smallest y-value of a function.
