What is the equivalent of pie divided by 3 radians in degrees

a: 30 degrees
b: 45 degrees
c: 60 degrees
d: 90 degrees

C. 60 degrees

Step-by-step explanation:

The formula to convert radians to degrees is: radians * 180/pi = degrees

So for this specific question your equation will be: pi/3 * 180/pi

1. You start by canceling the 2 pi

2. Next you multiply 1/3 * 180/1 to get 180/3

3. Lastly you divide 180/3 to get 60 degrees

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
