Answer:
3rd option
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (- 1, - 25 ) , then
f(x) = (x - (- 1) )² - 25 , that is
= (x + 1)² - 25 ← expand using FOIL
= x² + 2x + 1 - 25
= x² + 2x - 24
This equation simplified would be
-y(-5y+6)
Answer:
1) 34º
2) 52º
3) 56º
4) 94º
Step-by-step explanation:
let 3 be x
let 1 be y
let 2 be z
let 4 be j
180=86+38+x 56=x
90=56+y 34=y
180=86+j 94=j
180=34+z+94 52=z
kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk
