## anonymous one year ago T=(N-3.99) / 0.17 n is the number of women enrolled ( in millions) t represent the number of years Use the new formula in part b to estimate the year in which women's enrollment will reach 13 million

1. anonymous

I did that but it came out weird numbers instead of the year

2. Astrophysics

What does the 3.99 mean, what does 0.17 mean

3. Astrophysics

What is part a

4. Astrophysics

You need to give us all the information

5. anonymous

well the original formula is n=0.17t + 3.99

6. anonymous

but they asked me to solve for t using the equation n=0.17t + 3.99 in part b

7. Astrophysics

This is all vague, you're just throwing out formulas and not explaining what they are

8. anonymous

okay let me send a pic

9. Astrophysics

Alright

10. Astrophysics

Oh I see...

11. Astrophysics

n = 13

12. anonymous

13. Astrophysics

Because it states its in millions

14. Astrophysics

And initially your year is 1970, I can't really read it as it's a very blurry pic

15. anonymous

16. Astrophysics

Yeah so all you have to do is plug in n = 12 as it's asking for that, and then you will get a number of years, and you add that to your initial year which is 1970 that will give you the year where 12 million woman were in college.

17. Astrophysics

You can test with the other results as well to make sure, try n = 10, you will see you get 2005.

18. Astrophysics

Make sense?

19. anonymous

oh okay I got it. thank you very much

20. Astrophysics

For example $N=0.17t+3.99$ lets make n = 10 this means 10 million woman $10=0.17t+3.99 \implies t = \frac{ 10-3.99 }{ 0.17 } = 35$ 1970+35 = 2005

21. anonymous

yea I got 2017 for the answer. thank you again ~

22. Astrophysics

Np

23. Astrophysics

That's for 12 years, ok I see they are asking for 13 years in part C so do that as well haha

24. anonymous

yea I noticed lol
