The table below contains information about the area and side length of several squares. Square Name Side Length Area X 5 25 Y ? 32.21 Z 9 81 What is the best approximation for the length of the side of Square Y, rounded to two decimal places? Select one: O A. 6.90 O B. 5.67 O C.6.31 O D.5.35

answer: about 22.67

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
