The graph below shows the numbers of cups of kiwi juice that are mixed with different numbers of cups of lemon-lime soda to make servings of kiwi soda: What is the ratio of the number of cups of kiwi juice to the number of cups of lemon-lime soda? (5 points)

4:1

Step-by-step explanation:

4 cups of kiwi juice for every cup of lemon lime soda

4 to 1 (4:1)

Step-by-step explanation:

Take any pinpoint on the graph, and notice that for every 1 cup of soda (x-axis), there's 4x the amount of cups of juice (y-axis). Another way is to take any of those pinpoints, divide the number on the y-axis (left) by the number on the x-axis (bottom)... so 4/1, 8/2, 12/3 and so on. As you go up, they're all bigger fractions of the same thing: 4/1. Hope this helped!

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
