Please help this is due today. The graph shows the relationship between the number of gallons in a pool and the house it takes to drain the pool. Use the graph to answer the following...
A) determine the equation
B) what does the m, the slope/rate of change mean in the context of the problem
C) what does that b, y-intercept mean in the context of this problem

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

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
