Find the missing side length of a right triangle length 6 height 8 and hypotenuse unknown
2 answers:
Answer: 10
Step-by-step explanation:
You need to apply the Pythagorean Theorem:
Where "a" is the hypotenuse and "b" and "c" are the legs of the right triangle.
Since you need to calculate the value of the hypotenuse, you need to solve for "a":
You know the lenght of two sides of the right triangle (6 and 8) Then, you can substitute these values into .
Therefore, the hypotenuse of this right triangle is:

The first thing to do is to get the graph. That's below. That is a very wicked looking graph. I'm not sure what happens at 0. I'm not sure it is continuous at 0. That's something to make a fuss over because x = 0 is one of the x intercepts.
y = - x^(2/5)(x(5/5) + 7).
y = - x^(2/5)(x + 7)
So one of the x intercepts is 0 and the other one is -7.
The reasons are known because the factors can be equated to 0. It does not look to me like there is exact symmetry. There is a local minimum however at what the graph says is (-2,-6.5 or so)
You could differentiate that to find the exact point, but you are not asked for that.
So the domain is from -∞ to zero and 0 to plus ∞ I think you have to exclude 0 even though it is an x intercept.
The graph decreases from -∞ < x < -2
It increases from -2 < x < 0
It decreases form 0< x < ∞
