A remote control truck at a constant rate of 108 feet in 6 seconds

idk if this is what you wanted or not, but I will tell you the feet per second, because that is what it sounds like you want: The truck travels 18 feet every second

Step-by-step explanation:

all you have to do is divide 108 by 6, and the answer is 18 equation:

108 / 6= 18

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 would have to be 3/0
