2 hours * (47 miles / hour) = 94 miles

multiply the value in miles per hour by the conversion factor '1.609344'.

So, 2.2 miles per hour = 2.2 × 1.609344 = 3.5405568 kilometers per hour.

Let f(x) = cos(x) + 2x.<br> Where does f have critical points?
adell [148]

Answer:

<em>f</em> has no critical points.

Step-by-step explanation:

We are given:

f(x)=\cos(x)+2x

A function has critical points whenever its derivative equals 0 or is undefined.

Differentiate the function:

f'(x)=-\sin(x)+2

Since this will never be undefined, solve for its zeros:

0=-\sin(x)+2

Hence:

\displaystyle \sin(x)=2

Recall that the value of sine is always between -1 and 1.

Thus, no real solutions exist.

Therefore, <em>f</em> has no critical points.

Find the number whose 13% is 65.​
vodomira [7]

Answer:

500

Step-by-step explanation:

A = the unknown number that we need to find

A x 13/100 = 65

=> A x 13 = 6500

=> A = 6500 / 13

=> A = 500

13% of 500 is 65.

Let's check whether the answer is correct or not.

=> 500 x 13/100

=> 5 x 13

=> 65.

So, the number whose 13% is 65 is 500
