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
Answer:
<h2>
3.6° and 86.4°</h2>
Step-by-step explanation:
24x - measure of an angle
x - the measure of a complementary angle
Complementary angles adds to 90°
x + 24x = 90°
25x = 90°
x = 90°÷25
x = 3.6°
24x = 24·3.6° = 86.4°
