( - 6, 0).(2, 0 ) , vertex = ( - 2, - 16)
to find the x-intercepts set f(x) = 0
x² + 4x - 12 = 0
(x + 6)(x - 2) = 0 ( equate each factor to zero and solve for x )
x + 6 = 0 ⇒ x = - 6
x - 2 = 0 ⇒ x = 2
x- intercepts are ( - 6, 0),(2, 0)
given the quadratic in standard form : y = ax² + bx + c
the x-coordinate of the vertex = - ![\frac{b}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7B2a%7D)
here a = 1 , b = 4 and c = - 12
x- coordinate of vertex = -
= - 2
substitute this value into the equation for y-coordinate
x = - 2 → y = 4 - 8 - 12 = - 16
vertex = ( - 2, - 16)
Answer:
96°
Step-by-step explanation:
We assume you intend ...
ΔLMN ~ ΔQRS
Then corresponding angles have the same measure:
∠M = ∠R = 26°
∠L = ∠Q = 58°
∠N = ∠S = 180° -26° -58° = 96° . . . . sum of a triangle's angles is 180°
The measure of angle S is 96°.
A would be the answer.
Step-by-step:
Pythagorean theorem-
a^2+b^2=c^2
24^2+45^2=c^2
576+2025=c^2
2601=c^2
square 2601= square c^2
51=c
Answer:
$38
Step-by-step explanation:
He earned $62 in total, and earned $24 in the morning, so we can subtract we he earned in the morning to what he earned in total to figure out how much he made in the afternoon. 62 - 24 = 38
