I see your last line is : c(x) = 0.9(x^2-10)^2 + 101.1
Let y = x^2, then c(y) = 0.9(y-10)^2 + 101.1
Apparently, c(y) is a parabola, min is 101.1 when y = 10, max is infinity
So let x^2 = 10 -> x = sqrt(10) or -sqrt(10), min is 101.1, max is infinity
Answer: Yes
Step-by-step explanation: 144 is a perfect square. In other words, it's possible to find a whole number that can be multiplied by itself that gives us 144.
In this case, we multiply 12 by 12 or 12² to get 144 which means 144 is a perfect square. Also, it's on our perfect square list which I will attach below.
Hey there!!
Jason = 800 + Paul
Alex = Jason - 150
How much more does Alex have the Paul?
Let's take the equation of Alex
... Alex = Jason - 150
... Add 150 on both sides
... Alex + 150 = Jason
Now we have the equation for Jason,
... Jason = 800 + Paul , and we got Alex + 150 = Jason
... Now let's plug in the values
... Alex + 150 = 800 + Paul
Subtract 150 on both sides...
Alex = 800 - 150 + Paul
... Alex = 650 + Paul
Now we got the answer for our question :
The answer - Alex has $650 than Paul.
Hope my answer helps!!
