To make this easier, you want to do 5 1/2 into a decimal. 5.5, next divide to find her pace per minute. 12/ 5.5 =2.1818
Multiply that by 60, and your answer is 130
The coefficient of the squared expression is 1/9
<h3>How to determine the coefficient of the squared expression?</h3>
A parabola is represented as:
y = a(x - h)^2 + k
Where:
Vertex = (h,k)
From the question, we have:
(h,k) = (-2,-3)
(x,y) = (-5,-2)
So, the equation becomes
-2 = a(-5 + 2)^2 - 3
Add 3 to both sides
1 = a(-5 + 2)^2
Evaluate the sum
1 = a(-3)^2
This gives
1 = 9a
Divide both sides by 9
a = 1/9
Hence, the coefficient of the squared expression is 1/9

If you use the PEMDAS order of operations rule, then you can see that multiplication has to come first Then you have to subtract four from that
Is it just 7+222? if so it would be 229
