What was your final answer for the number of tennis balls it would take to fill up the classroom?
Remember to use these numbers:
Here's your numbers for filling up the Classroom B107 at NCHS with tennis balls:
Length of B107:23 feet
Width of B107:30 feet
Height of B107: 9 feet
Length of box: 8.5 inches
Width of box: 12.5 inches
Height of box: 18 inches
125 tennis balls fit in a box

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

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

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
