Answer:

f^{-1}(x)= \frac{1}{2}x

Step-by-step explanation:

Given

f(x) = 2x

Required:

Find f^{-1}(x)

f(x) = 2x

Replace f(x) with y

y = 2x

Swap both variables

x = 2y

2y = x

Make y the subject

y= \frac{1}{2}x

Replace y with f-1(x)

f^{-1}(x)= \frac{1}{2}x

ASNWER CORRECTLY AND YOU WILL GET 40 POINTS ALONG WITH BRAINLIEST
FromTheMoon [43]

Answer:

60

Step-by-step explanation:

What we know:

  • ABD is a straight angle, it measures 180 degrees
  • Angle CBA + CBD = 180 degrees
  • Angle GFH = CBA (they are alternate exterior angles)

Equation:

GFH + CBD = 180

Substitute:

3x + 6x = 180

Add:

3x + 6x = 180

9x = 180

Divide:

9x = 180

/9     /9

x = 20

Substitute:

GFH = 3x

GFH = 3(20)

GFH = 60

m<GFH is 60°

If log65 = 1.812 what is the value of log(base 1000)65 ? 0.0604 0.604 0.1812 0.001812
ioda
If we have:

logₐy = (logₓy) / (logₓa)       By change of base formula.

log₁₀65 = (log₁₀₀₀65) / (log₁₀₀₀10)

(log₁₀₀₀65)  = log₁₀65 * (log₁₀₀₀10)

log(₁₀₀₀10) =  1/ (log₁₀1000) = 1/(log₁₀10³) = 1/3

(log₁₀₀₀65)  = (log₁₀65) * (log₁₀₀₀10)

(log₁₀₀₀65)  = 1.812 * (1/3)       

(log₁₀₀₀65)  = 0.604

I hope this helps.
