(ASAP) Teresa is maintaining a camp fire. She can keep the fire burning for 4 hours 6 with 6 logs. She wants to know
how many logs (y) she needs to keep the fire burning for 18 hours. She assumes
all logs are the same.
How many logs does Teresa need to maintain the fire for 18 hours?
logs

dont understand

step-by-step explanation:

what level of math? also i don't need to be paid if i can 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
