Answer:

a = - 2, b = 4, c = - 3

Step-by-step explanation:

The standard form of a quadratic equation is

ax² + bx + c = 0 ( a ≠ 0 )

Compare - 2x² + 4x - 3 = 0 to the standard, giving

a = - 2, b = 4, c = - 3

Wewaii [24]

<u>Answer:</u>

The sprinkler will cover 104.66 square feet

<u>Explanation:</u>

A water sprinkler covers a circular area with a diameter D= 20 feet

and radius r = 10 feet

Arc measuring degrees = 120 degree

Area of the Arc = $\frac{120}{360} \times \pi \times r^2$

= $\frac{1}{3} \times \pi \times 10^2$

= $\frac{1}{3} \times 3.14 \times 10 \times 10$

= 104.66

The sprinkler will cover an arc area covering 104.66 square feet
