The answer is
To solve this problem, just plug
into the function and simplify.
This is the concept of geometry, the function given by f(x)=cos^x
can be written as cos y=x
The domain if the function is [-1,1] and the range is given by [0,π] where π=180°
2.2 is the answer because when you divide its a decimal
1) pages per minute is the rate. the rate is the slope pages/minutes = .4
y=.4x or y=2/5(x)
2)birdhouses per day is the slope. = .6
y=.6x or y=3/5(x)
3) miles per hour is the slope. 500/8=62.5
y=62.5x
4) square feet per minute is the slope. 40/9 =4.444444444
y=4.4444444444x or y=40/9(x)
5)miles per minutes is the rate. 5/41 is the slope.
y=5/41(x)
6) the rate is square feet per minute. 450/30=15
y=15x
