<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:
The solutions are:
In which:
Item a:
The coefficients are a = 2, b = -3, c = -4, hence:
Item b:
The coefficients are a = 1, b = 2, c = 2, hence:

I think the shaded region for this problem will the part of the circle that is not covered by the triangle. First, determine the area of the circle by the equation,
A = πD²/4
Substituting the given diameter,
A = π(16 ft)²/4 = 200.96 ft²
Then, determine the area of the triangle with the equation,
A = bh/2
Since the base of the triangle is the diameter, b = 16 ft. Then, its height will be half the height and that will be equal to 8 ft. Substituting,
A = (16 ft)(8 ft) / 2 = 64 ft²
The difference between the two areas is 136.96 ft².
The correct answer is 127.

Answer:
mABC = 117 degrees
mBCD = 90 degrees
mDEA = 90 degrees
mCDE = 127 degrees
Step-by-step explanation:
Since ABCDE is congruent/equal to FGHIJ, then each angle corresponds with the angle in the other shape. I.E., A = F, B = G, C = H, etc. Finding the angle for ABC is finding the angle for FGH. This works only because there was no changing the places of the points individually. :)

because you keep 8/3 and the multiplication sign and then flip the 24/4 to 4/24 and then solve for that and then the simplified answer would be 4/9
