You volunteered to help set up water stations for a marathon. The first station is 3.46 mi from the starting point The second station is 6. mi from the first station. The third station is 8.98 mi from the second station. The last station is 6
mi from the third station. What is the distance of the last station to the finish line if a marathon is approximately 26.2 mi
long?

answer: hey there,

the answer you are looking for is a..

hope this you!

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

cool? what is the actuall ?
