Given the equation of the function:
The given function represents a parabola
We will make a complete square to find the coordinates of the vertex
The coefficient of x = 4
Half the coefficient of x = 2
Square it give = 4
So, we will add and subtract 4
Compare the last equation with the vertex form of the parabola
So, h = -2, k = -11
So, the answer will be the coordinates of the vertex = (-2, -11)
Answer:
11x + 12
Step-by-step explanation:
9x + 3x = 11x
8 + 4 = 12
Answer:
A) y = -1/2x + 1/2
Step-by-step explanation:
Find the y-intercept(when x = 0), which is 1/2.
Find the slope: m = y2-y1 / x2-x1
I used points: (3, -1), (-3,2)
m = 2 - (-1) / -3 - 3
m = 3 / - 6
m = -1/2
plug this into the slope intercept form equation: y = mx + b
y = -1/2x + 1/2
Answer:56.52m, Eugene used a wrong formula
Step-by-step explanation:
diameter=18m
π=3.14
Circumference of circle=π x diameter
Circumference of circle=3.14 x 18
Circumference of circle=56.52m
Eugene used a wrong formula
Circumference of circle=2 x π x diameter
instead of
Circumference of circle=π x diameter
Answer:
18/25
Step-by-step explanation:
And as any numbers can divide exactly both numbers, then “18/25” is the simplest form of “. 72”.
