Find the function value f(x^2)=|x|+4

grigory [225]

Answer:

Step-by-step explanation:

$f(x)=\sqrt{x}+4$

let s double check

$f(x^2)=\sqrt{x^2}+4$

and we know that $\sqrt{x^2} = |x|$

so $f(x^2)=|x|+4$

so the solution is

$\boxed{f(x)=\sqrt{x}+4}$

Calculate the length of a triangle if another length is 15 feet and the hypotenuse is 39 feet.

Y_Kistochka [10]

We have to use Pythagorean theorem that says :

$a^2+b^2=c^2\\\Rightarrow a^2+15^2=39^2\\a^2=39^2-15^2\\a=\sqrt{1296}\\a=36$

The missing length of the triangle is : 36 feet
