F(s)=e^-2s/s^2-2e^-2s/s62
That's not a function.
Since a vertical line hits the graph more than once, if fails the test. (See graph below)
If it is a function, any vertical line you draw can only hit the graph once.
Answer:
- Circumference: 12.56 yd
- Area: 12.56 yd²
Step-by-step explanation:
The circumference is given by ...
C = πd
C = (3.14)(4 yd) = 12.56 yd
The area is given in terms of diameter by ...
A = (π/4)d²
A = (3.14/4)(4 yd)² = 12.56 yd²
According to the question,
Let,
"n" represent the number of miles semir walked.
"y" represent the number of miles sarah walked.
Now, according to the question,
y = 2n - 5 ........................this is your equation
Also,
the question states, each of them collect $18 in pledges for every miles walked.
Given,
Sarah collected $450
Now,
Using unitary method,
Sarah collects $18 for 1 mile
Sarah collects $1 for (1 / $18) mile
Sarah collects $450 for (1 / 18) * 450 mile
= 25 miles
So, Sarah walks 25 miles.
Now,
Taking equation,
y = 2n - 5
Since, y is the no. of miles sarah walked, we can write 25 in place of "y" So,
(25) = 2n - 5
25 + 5 = 2n
30 = 2n
30 / 2 = n
15 = n
Since, "n" is the no. of miles that semir walked, Semir walked 15 miles.
