With the information given, we deduce that the parabola is
Reflecting a function over the x axis means to change its sign. After the reflection, the parabola becomes
And to shift down a function, you subtract the shift from the equation: the equation becomes
Similarly, the other function is reflected over the x axis (sign change) and shifted up 3 (add 3 to the equation):
In order to compute the y intercept, we simply have to evaluate the functions at x=0: for the parabola we have
For the other function, we have
Answer:
The area of the shaded region is: 32.25m^2
Step-by-step explanation:
Given
See attachment for rectangle and semicircles
Required
The shaded region
We have:
--- length of the rectangle
This means that the diameters of the three circles add up to 30m.
So, the diameter of 1 is:
The area of one circle is:
The area of the three circles is:
The area of the rectangle is:
Where r is the radius of the circle
And
So, we have:
So, the shaded region is:
