Answer:
hypotenuse is 22.47 m
Step-by-step explanation:
The length of both legs of a right angle triangle are 8m and 21 m
We need to find the hypotenuse
To find hypotenuse we use Pythagorean theorem
Hypotenuse is AC and other two legs are AB and BC
![AC^2 = AB^2 + BC^2](https://tex.z-dn.net/?f=AC%5E2%20%3D%20AB%5E2%20%2B%20BC%5E2)
Hypotenuse ^2 = 8^2 + 21^2
hypotenuse = ![\sqrt{8^2 + 21^2}](https://tex.z-dn.net/?f=%5Csqrt%7B8%5E2%20%2B%2021%5E2%7D)
= ![\sqrt{64 + 441}](https://tex.z-dn.net/?f=%5Csqrt%7B64%20%2B%20441%7D)
= ![\sqrt{505}](https://tex.z-dn.net/?f=%5Csqrt%7B505%7D)
= 22.47
So the length of the hypotenuse is 22.47 m
Answer:
x/2 + 21 = 36
First we get rid of constants to isolate the variable.
In order to do that we must do the inverse operation.
Inverse operation of addition is subtraction.
-21 -21(subtracting 21 from both sides, whatever we do to the left side we do it to the right side too)
x/2 = 15
inverse property of division is multiplication
x2 x2
X = 30

Answer:
Even function
Step-by-step explanation:
Both powers of x in f(x) = -3x^4 + 7x^2 are even, so f(x) = -3x^4 + 7x^2 is an even function.
