So this is a Pythagorean problem where
A^2+b^2=c^2
a is 2
X is b
5 is c
Plug that into the equation and get
4+b^2=25
B^2=21
B=sqrt(21)=4.6kilometer
The C(x) equation is a parabola with a squared "x" and a positive leading term coefficient, meaning, is a vertical parabola and it opens upwards
the lowest point, or lowest cost value, it reaches, is the U-turn point, or vertex

so, the lowest cost is at
Given:
Division problem:

To find:
The solution for the given division problem.
Solution:
We have,

Here, 4x^4-4x^2-x-3 is the dividend and (2x^2-3) is divisor.
Using the long division method we get


(After subtraction)

(After subtraction)
Now,

Therefore, the required solution is
.
Answer:
No matter if you are on Earth, the moon or just chilling in space, your mass does not change. But your weight depends on the gravity force; you would weigh less on the moon than on Earth, and in space you would weigh almost nothing at all. Where ever you are, your mass will always stay the same.
The answer is obtuse triangle
