Answer:
1. 5 hours
2. 4 hours
Reason:
Formula for speed is speed =
, if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.
Answer:

Step-by-step explanation:
Exponential growth function:
The exponential growth function for a population, after t years, is given by:

In which P(0) is the initial population and r is the growth rate.
A warren of rabbits has a population of 350. The population is increasing at a rate of 3% per year.
This means that 
So


How can you write an exponential growth function to find the monthly growth rate?
Monthly growth rate means that the time is divided by 12(as one year has 12 months), so the equation will be:


Answer:
Ask your parents if no one have the answer.
Step-by-step explanation:
sorry if I don't have the answer.
The answer is 4x-1 hope it helps. :D
Answer:
x=1
Step-by-step explanation:
13x=13
x=1
All you do it get rid of the lowest x value, and put the non x values to the right. Divide by the coefficient, and you'll get 1.
