The first derivative of f is given by LaTeX: f'\left(x\right)=\frac{\cos^2x}{x}- \frac{1}{5}f ′ ( x ) = cos 2 ⁡ x x − 1 5. How many critical values does f have on the open interval LaTeX: \left(0,10\right)( 0 , 10 )? Enter an integer value and 0 if no critical values.

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

answer is c

step-by-step explanation:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
