Answer:
so, i am pretty sure all this is saying is move the plot nine units down the y axis. so you'd plot (5, 7).
Step-by-step explanation:
i hope this helps, let me know if this is right.
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
Step-by-step explanation:

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:

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 
So


How many hours does it take for the size of the sample to double?
This is t for which P(t) = 2P(0). So







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