9
Step-by-step explanation:
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:
It would be 29.
Step-by-step explanation:
4/12ths is 1/3 when simplified. 1/3 in decimal form is .33
1/5; 1/5 is .2
¼; ¼ is .25
5/25: 5/25 is .2
6/24; 6/24 is .25
all of these fractions are near .33 but aren't equivalent to it.
