A contagious disease is infecting residents of a town of 7,300 residents. The number of residents infected t days after the disease has begun is given by the function f(t)=(7300)/1+500e^-0.5 t How many residents are infected with the disease after 6 days?

I was thinking that as well! Thanks!

I do not think these answers are right. I get somethin else and 5 is not an option. Here are the choices A. Minimum is 25 B. Minimum is -51 C. Maximum is -1 D. Maximum us -51

**Algebra**

Consider the quadratic function f(x) = – x^2 + 10x – 26. Determine whether there is a maximum or minimum value and find that value.

**Algebra**

If this was a -f(x) then it would be odd? I think I understand now..Am I correct?

**Algebra**

Yes I read them, but misinterpreted them I suppose. So this is an even function because x is being represented rather than y and this would be an even function resulting in a reflection in the y-axis? I will sketch it out.

**Algebra**

So I would say that the answer would be that f can be both odd and even then. Am I correct?

**Algebra**

A. f is an odd function B. f is an even function C. f is neither odd nor even D.f is both odd and even Totally confused and would appreciate some insight. Thanks!

**Algebra**

Confused Please Help! Thanks! Let f(x) = 1 – 3x^2. Which of the following is true? Give a brief explanation. A. f is an odd function B. f is an even function C. f is neither odd nor even D. f is both odd and even

This is interesting, I got the first one correct for y = -5 because x = 0 but still do not get how you come up with 5/2 for the slope of the parallel line and the slope of the perpendicular one either? Can you please explain. Thanks!

I saw the answer, but my choices are as follows: Thank you for your help but which one would it be? the thrid one or forth? I know the 1st two are no goes. You opinion please? Thanks! (m + 4) (a – 8) (m + 4) (a + 8) (m + 4) (2a – 2) (m + 4) (a2 – 2)

**Math**

Ok so the answer is (m + 4) (2a – 2) OR (m + 4) (a2 – 2)

**Math**

So then the answer would be (m + 4) (2a – 2) OR (m + 4) (a2 – 2)

Factor (m + 4) (a – 5) + (m + 4) (a + 3) I cut it down to 2 possibilities. (m + 4) (2a – 2) (m + 4) (a2 – 2) Think it's this one
