What is the equation of a parabola with vertex (-2,1) and a=-4 y= 4(x + 1)^2 – 2

y= –2(x – 1)^2 – 4

y= -4(x + 2)^2 + 1

y = -4(x – 2)^2 + 1

sine

step-by-step explanation:

what

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
