Answer:
<u>graphically</u> :
The graph is symmetrical about the origin.
Then it represents an odd function.
<u>symmetry </u>:
The origin is a center of symmetry.
The x (the second one) has a one in front of it so 5x *1x=5x so 5x-4 is the answer
Answer:
It is linear since it is a straight line.
Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
