Replace f(x) with x⁸

1) f(x) + 2     →       x⁸ + 2

2) 3f(x)        →       3x⁸

3) f(-x)         →       (-x)⁸

4) f(x - 2)      →     (x - 2)⁸

5.\ \dfrac{1}{3}f(x)        →      \dfrac{1}{3}x^8

Ruby combines 8.27 liters of red paint with 6.65 liters of blue paint to make purple paint. She pours the paint equally into 2 c
Vesna [10]

Answer:

Step-by-step explanation:

Josie combines 8.27 liters of red paint with 6.65 liters of blue paint to make purple paint. This means that the total number of liters of paint in the mixture(purple paint) is

8.27 + 6.65 = 14.92 liters

She pours the paint equally into 2 containers, and has 1.56 liters of paint left over. This means that the amount of paint that she poured inside the 2 containers is

14.92 - 1.56 = 13.36 liters.

Therefore, the number of liters of paint in each container is

13.36/2 = 6.68 liters

The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate
amid [387]

Answer:

It takes 7.37 hours for the size of the sample to double.

Step-by-step explanation:

Continuous exponential growth model:

The continuous exponential growth model for populations is given by:

P(t) = P(0)e^{rt}

In which P(0) is the initial population and r is the growth rate parameter, as a decimal.

Growth rate parameter of 9.4% per hour.

This means that r = 0.094

So

P(t) = P(0)e^{rt}

P(t) = P(0)e^{0.094t}

How many hours does it take for the size of the sample to double?

This is t for which P(t) = 2P(0). So

P(t) = P(0)e^{0.094t}

2P(0) = P(0)e^{0.094t}

e^{0.094t} = 2

\ln{e^{0.094t}} = \ln{2}

0.094t = \ln{2}

t = \frac{\ln{2}}{0.094}

t = 7.37

It takes 7.37 hours for the size of the sample to double.
