Answer:
Step-by-step explanation:
In order to find the circumference of a circle, we can use the formula for it, which is .
This formula states that r, the radius, multiplied by pi (3.14..) doubled will be the circumference.
Pi rounds to 3.14 usually.
So our new formula is:
We can now multiply.
Hope this helped!
To find the slope of the expression:
We need to remember that this is the Slope-intercept Form of the line equation:
Where
m = slope
b is the y-intercept.
Therefore, the slope of the line equation above is m = 3.
The <em><u>correct answer</u></em> is:
Explanation:
An exponential function is of the form
, where a is the initial population, b is 1 plus the amount of yearly change, and x is the number of years.
For our problem, a, the initial population, is 1500.
The yearly change is 6.3%; 6.3% = 6.3/100 = 0.063. Since it is decreasing, this is negative; 1+(-0.063) = 0.937.
We use t as the number of years.
This gives us
