Which function in vertex form is equivalent to f(x) = x2 + 8 – 16x?

f(x) = (x – 8)2 – 56
f(x) = (x – 4)2 + 0
f(x) = (x + 8)2 – 72
f(x) = (x + 4)2 – 32

b. x + 1

i'am smart

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

step-by-step explanation:

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
