The length of a rectangle is 2 ft shorter than 5 times its width, x. The area of the rectangle is less than 100 ft. Which inequality can be used to determine the maximum width (ft) of the rectangle?
OA. 5x2 – 2x < 100
OB. 5x2 – 2x > 100
C. 5x2 + 2x > 100
D. 5x2 + 2x < 100

D

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
