Answer:
#1
y = x² - 8x - 20
y = (x - 10)(x + 2),
zero's are (10, 0) and (- 2, 0)
Vertex is:
x = -8/-2 = 4, y = 4² - 8*4 - 20 = -36
Correct choice is
A
#2
x² + 1/3x = 4
x² + 2*x*(1/6) + (1/6)² = 4 + 1/36
(x + 1/6)² = 4 1/36
Correct choice is
A
#3
(-√-1) = -i
i² = -1 ⇒ i²ⁿ = -1
i²ⁿ⁺¹ = -i
Correct choice
A or B
