For this case we have that by definition, the area of a circle is given by:
Where:
r: It is the radius of the circle.
So, we have that the area of the shaded region is given by:
We divide between 4 on both sides of the equation:
We apply root to both sides:
We choose the positive value of the root:
Finally, the value of "x" is 9
Answer:
The correct answer is: [B]: "y-intercept" .

Answer:
x < 21.9
Step-by-step explanation:
Just follow the same rules as if you were solving for x
<u>14.2 + 15.5</u> + x < 51.6 = Combine like terms
<u>29.7</u> + x < 51.6 = Subtract 29.7 to isolate x
x < 21.9

Answer:
45 meters
Step-by-step explanation:
The equation is given in vertex form:
h(t) = a(t -b)^2 +c
where (b, c) is the vertex (maximum).
The values of the parameters are ...
a = -5, b = 3, c = 45
Then the maximum height is (time, height) = (3, 45).
The maximum height of the ball is 45 meters.
