Answer:

13. She will have saved 1020 in 12 months and 467.5 in 11. 14. In 1 month she'll have saved 42.5 in 1 month and 212.5 in 5 months. 15. in 3 months she'll save 125 and 190 in 4 months. 16. The rate of change is 42.5. 17. It depends on your thoughts on what was more challenging, and knowing the rate of change can tell you half of certain amounts of money earned or what the difference between her earning months are. 18. I have no idea the y intercept someone else might be able to help you with that though. 19. I don't know that either someone else might help better.

nignag [31]

A group of k elements can be chosen from a group of n elements in $\frac{n!}{k!(n-k)!}$ ways.

$(^6 _3)=\frac{6!}{3!(6-3)!}=\frac{6!}{3! \times 3!}=\frac{3! \times 4 \times 5 \times 6}{3! \times 6}=4 \times 5=20$

There are 20 different 3-member groups.

I need help to solve this and also Hearn will the bacteria be over 100,000

lapo4ka [179]

Hello! Let's look at the two parts of this question.

Complete the table:

In this case, you just substitute the value of "hour" into the equation, for the value of t. For example:

P(0) = 120 $(2)^{0}$

P(0) = 120 (1)

P(0) = 120

Therefore, the number of bacteria for hour 0 is 120.

You can do this for the next ones. Hour 1 = 240, hour 2 = 480, and so on. (In this case, you can keep multiplying by 2)

Estimate when there will be more than 100,000 bacteria:

Set the final value of P(t) = 100,000, then solve.

100,000 = 120 (2 $)^{t}$

833.33 = (2 $)^{t}$

t = $log_{2}833.33$

t = 9.702744108

So your answer would be around 9.7 years, or, around 10 years.

Hope this helps!
