PLEASE HURRY write the equation of the inverse function y=1/2cos^-1(pix)-3
GaryK [48]

Answer:

f^{-1}(x) = \frac{cos(2x+6)}{\pi }

Step-by-step explanation:

y = \frac{1}{2} cos^{-1} (\pi x)-3

Firstly, we've to interchange the variables.

x = \frac{1}{2} cos^{-1}(\pi y)-3

Solving for y

x = \frac{cos^{-1} \pi y}{2} -3

Adding 3 to both sides

x+3 = \frac{cos^{-1}(\pi y)}{2}

Multiplying 2 to both sides

2(x+3) = cos^{-1} (\pi y)\\2x+6 = cos^{-1} (\pi y)

Taking cosine on both sides

\pi y = cos (2x+6)

Dividing both sides by y

y = \frac{cos(2x+6)}{\pi }

Replace y by f^{-1}(x)

=> f^{-1}(x) = \frac{cos(2x+6)}{\pi }

Find how many years it takes for money to triple when invested at an annual interest rate of 4.3% compounded continuously. That’
malfutka [58]

9514 1404 393

Answer:

  25.5 years

Step-by-step explanation:

The multiplier for continuous compounding at annual rate r for t years is ...

  e^(rt)

You want the value of t when that is 3 and r=0.043.

  3 = e^(0.043t)

  ln(3) = 0.043t

  t = ln(3)/0.043 ≈ 25.549 . . . . years
