Answer:
n = ![\sqrt{32}](https://tex.z-dn.net/?f=%5Csqrt%7B32%7D)
Step-by-step explanation:
The 2 right triangles inside the larger right triangle are similar , so corresponding sides are in proportion
=
( cross- multiply )
n² = 32 ( take the square root of both sides )
n = ![\sqrt{32}](https://tex.z-dn.net/?f=%5Csqrt%7B32%7D)
Answer:
Step-by-step explanation:
Answer:
it's inverse is:
f(x)^-1 = (x+10)/2
Step-by-step explanation:
f(x)= 2x -10
y= 2x -10 [ let f(x) be y]
interchange value of x and y
x=2y -10
(x+10) = 2y
y=(x+10)/2
f(x)^-1 = (x+10)/2
Answer:
n = 8
Step-by-step explanation:
-4 + 8 = n/2
4 = n/2
4 x 2 = n
8 = n
