Answer:
45%
Step-by-step explanation:
With these types of problem, just remember to replace "is" with "="
and remember 60% also = 0.6
and let's called the amount x
so
486 = 0.6x
divide both sides by 0.6
and you'll get x which is the amount you are looking for
To find the rate, divide the number divided by the amount of minutes. So 775 divided by 12.5 which is 62.
62 steps per minute
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)
