Step-by-step explanation:
<u>Step 1: Define</u>
f(x, y) = 2x - 3y + xy²
(3, -1) is x =3 and y = -1
<u>Step 2: Evaluate</u>
- Substitute: f(3, -1) = 2(3) - 3(-1) + 3(-1)²
- Exponents: f(3, -1) = 2(3) - 3(-1) + 3(1)
- Multiply: f(3, -1) = 6 + 3 + 3
- Add: f(3, -1) = 9 + 3
- Add: f(3, -1) = 12
Answer:
706.5 sq ft
Step-by-step explanation:
If the farthest point is 30 feet away, the diameter of the circle is 30, so the radius is 15.
Area of a circle is pi r*2
3.14 x 15^2 = 706.5 sq ft
