Shaded area=π(5²-4²)=π(25-16)=9π≈9×3.14=28.26 square units
Answer:
Linear functions.
Exponential functions.
Step-by-step explanation:
An example of an arithmetic sequence is 1, 3, 5, 7, common difference is 2 and is modelled by the linear function
1 + 2(n -1).
A geometric sequence might be 2, 4, 8, 16 where there is a common ratio of 2 and is modelled by 2.(2)^n-1).
Answer:
y = 1/2x -1
The slope is increasing by 2/4, which can be reduced to 1/2. You can find this by doing rise over run.
The y intercept is -1

Answer:
x = 9
Step-by-step explanation:
Corresponding segments are proportional, so ...
(2x -8)/5 = (x -3)/3
3(2x -8) = 5(x -3) . . . multiply by 15
6x -24 = 5x -15 . . . . eliminate parentheses
x = 9 . . . . . . add 24-5x
