Aflower box in the shape of a right rectangular prism is made of thin metal, shown below. the box has length 90 centimeters (cm), width 45 cm, and height 45 cm. the box is 85 percent filled with soil. each bag of soil holds 1 cubic (ft^3), and 1 ft^3 is approximately 28,316 cubic centimeters (cm^3). how many bags of soil are needed to finish filling the flower box?

a. 1 bag

b. 2 bags

c. 6 bags

d. 7 bags

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

b. ol
