sylvia read that the height of the empire state building is 443.2 m and wants to build a scale model of the building in her room. she knows that the height of the ceiling in her room is 8 ft. write a scale that would allow a scale model of the empire state building in sylvia's bedroom so that
the top of the building would just touch her ceiling.

step-by-step explanation:

when you realize that you dont know just realize i just took a test and im so smart

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

the answer should be a. snail

the answer to 1/4x+5/3x-4=2-1/12x is x=3

hope this if needed hmu
