Answer:
it depends on how many students there are in each grade.
Answer:
f(x) = x⁴ - 8x³ + 25x² - 72x + 144
Step-by-step explanation:
f(x) = (x-4)²(x+3i)(x-3i)
= (x²-8x+16)(x²+9)
= x⁴ - 8x³ + 25x² - 72x + 144

Answer:
Step-by-step explanation:
Remark
Area of an entire circle = pi * r^2
Area of a sector = angle / 360 * pi * r^2
Givens
angle = 140
radius = 8
Solution
Area = (140/360) * 3.14 * 8^2
Area =0.3889 * 3.14 * 64
Area = 78.15
