What single decimal multiplier would you use to increase by 5% followed by a 20% increase?
sashaice [31]

Answer:

The single decimal multiplier is 1.26.

Step-by-step explanation:

Multipliers:

For a decrease of a%, we multiply by: \frac{100-a}{100}

For a increase of a%, we multiply by: \frac{100+a}{100}

For consecutive changes, we multiply the multipliers.

Increase of 5%

Multiply by \frac{100+5}{100} = \frac{105}{100} = 1.05

Increase of 20%

Multiply by \frac{100+20}{100} = \frac{120}{100} = 1.2

Consecutive:

1.05*1.2 = 1.26

The single decimal multiplier is 1.26.

Find the equation of the exponential function represented by the table below:
Allisa [31]

Answer:

  y = 0.1(4^x)

Step-by-step explanation:

An exponential function can be written as ...

  y = a(b^x)

where 'a' is the y-intercept, and 'b' is the ratio of terms with consecutive x-values.

The table tells us a=0.1, and b=0.4/0.1 = 4. The equation is ...

  y = 0.1(4^x)
