Answer: its 3
Step-by-step explanation:
i got it from google
First subtract the constant to the other side to simplify it for now
y-5=-x^2+6x
Then pull out a common factor so the coefficient is x^2
y-5=-1(x^2-6x)
Next you take 1/2 of the b value (-6) and square it to find your c value
[1/2(-6)]^2=9
After that plug 9 into your equation as your c value
y-5=-1(x^2-6x+9)
Adding the C-value (9) causes the equations to become unbalanced so you need to balance them back out by minus 9 to the other side
y-14=-1(x^2-6x+9)
Now you want to simplify the equation on the right side.
y-14=-1(x-3)^2
Finally you want to add the constant back to the right side.
y=-1(x-3)^2+14 <——— vertex form
maximum=(3,14)
Answer:
-2
Step-by-step explanation:
- and - is positive so -4+2 is -2
Answer:
The school's championship record is 5 m
Kaydeen must increase her personal best by 25%
Step-by-step explanation:
Find the school's championship record by dividing 6 by 1.2
6/1.2
= 5
So, the school's championship record is 5 m
Find the percentage that she has to increase her personal best to equal the national record, by finding the percent change
Divide the difference in the scores by Kaydeen's score
1.5/6
= 0.25
So, Kaydeen must increase her personal best by 25%
