Answer:
Step-by-step explanation:
Find the area of the shaded region in terms of r.
1. The area of the circle with radius r is
2. The area of the square with diagonal 2r is
3. The area of the shaded region is the difference
Since the area of the shaded region must be greater or equal to then
This inequality is solved only in positive numbers, because r cannot be negative.
Given:
The inequality is:
To find:
The values that are solutions to the given inequality.
Solution:
We have,
Adding 4 on both sides, we get
Divide both sides by -3 and change the inequality sign because -3 is a negative value.
Therefore, all the real values greater than -2 are the solutions to the given inequality.
No it can not if you don't understand why ask why
Answer:
Step-by-step explanation:
g(x) = x^2 + 6
f(x^2 + 6) = 2(x^2 + 6) + 1 = 2x^2 + 12 + 1 = 2x^2 + 13
