Use compatible numbers to find two estimates 1322 divided by 18
prisoha [69]
Compatible numbers is used to find estimate to a sum. The numbers are chosen because its 'simplicity' when they are multiplied, divided, added or subtracted.

Estimate one:

We can decrease the value 1322 to 1320 and 18 to 15
Then do the sum = 1320÷15 = 88
This estimate is not far from the actual answer 1322÷18 = 73.44..

Estimate two:

We can increase 1322 to 1330 and 18 to 20
Then do the sum 1330÷20=66.50
This estimate is also not far from the actual answer 73.44...

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 }
