Avi's pet hamster chubby loves to run in his hamster wheel. during one "race", avi counts 100100100100 rotations of the wheel. she wants to know how far chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm20 \text{ cm}20 cm20, space, c, m.

55/i dont know i do it for the points

step-by-step explanation:

16 is the absolute value

step-by-step explanation:

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

it is 10.6 according to my calculations
