what............there’s no pic
k = 5
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
Since the coefficient of the x² term is 1 then
add/ subtract (half the coefficient of the x-term )² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 + 14 = (x - 3)² + 5 → k = 5
For the equation to be true, the events A and B must be mutually exclusive.
Answer:
Step-by-step explanation:
D
All angles add to 180 (interior angles)
22+53+?=180
75+?=180
minus 75 both sides
?=105
third angle is 105 degrees
