Jaime claims that when you multiply a whole number by 100, the decimal point moves 2 places to the right. Salome argues that the decimal point only moves when you multiply a decimal by 100. Salome says that when you multiply a whole number by 100, the product has 2 extra zeros. Part A Explain each students point of view

Ok so i know Jaime is correct but i just need Part A

Step-by-step explanation:

Jaime is correct,

because when you turn a decimal into percent, you move the decimal two places, you are basically multiplying by 100.

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

hello! just here for points! though i wish i knew!
