Answer:
2x^2+4x-16
Step-by-step explanation:
The quadratic can be written as
f(x) = a(x-z1)(x-z2) where z1 and z2 are the roots
f(x) = a (x-2)(x- -4)
a is the leading coefficient
f(x) = 2(x-2)(x+4)
= 2(x^2 -2x+4x-8)
= 2(x^2 +2x-8)
= 2x^2 +4x-16
It would be the last graph because at the x-intercept, it crosses the 5
The distance between two points is calculated through the equation,
d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values from the given above,
d = √(4 - -4)² + (4 - -4)²
d = 8√2 = 11.31
The distance between the points is approximately equal to 11.31. The value that Jason presented is not the real distance because it does not account for the other set of coordinates.
I just helped my sister on this problem its kinda scary... :P
If you mean 1/3 and 3/5
Belinda has 135 beads in total.
Find 1/3 of 135.
135 ÷ 3 = 45.
Belinda uses 45 beads to make the bracelet.
Hope I helped :)
