Answer:
-11.
Step-by-step explanation:
f(x) = √(3 - 2x), x ≤ 3/2
let y = √(3 - 2x)
y^2 = 3 - 2x
2x = 3 - y^2
x = (3 - y^2)/2
So f-1(x) = (3 - x^2)/2
f-1(x) = (3 - 5^2) / 2 = -11.
x=3 and y = -1. ....thank uh.. ,
2 because it is the only number smaller than 5
The answer is D, 4.2. not what the person said
The length of x is 33.85 when rounded to the hundredth place.
You can start solving this by using the tangent function.
Tan(Angle) = opposite/adjacent
Since the angle is 28 and the opposite side is 18, we can set adjacent as x and solve.
Tan(28) = 18/x ---> Cross multiply
xTan(28) = 18 ---> Divide by Tan(28)
x = 18/Tan(28)
Which equals roughly 33.85
