Question:
A foal was 100 lb when it was born. It weighed 160 lb at 4 weeks and 220 lb at 8 weeks. At that rate of increase, about how many pounds will the foal weigh at 14 weeks?
Please, Please show all the work, I really need it. Thank you so much! :)

Question 454107: Hi, I am studying for a quiz on hyperbolas and one of the problems I am doing is this:
Write an equation in standard form for each hyperbola.
Length of transverse axis 10 and foci at (-7,18) and (-7,-8)
So far, I understand that it is vertical therefore the equation would be in the (y-k)^2/a^2-(x-h)^2/b^2=1
I am pretty sure I also got the center which was (-7, 5)
So now I have (y-5)^2/a^2-(x+7)^2/b^2=1
My problem is is that I don't know how to find what a and b are. I understand they come from the vertices and co-vertices but I don't think I fully understand the transverse axis.

Question 454238: (x+6)^2_______(y-4)^2
-------------- + ---------------- = 1
___12__________ 16
this is a ellipse formula. find the vertices and foci coordintes.
(the dash marks are fractions, the underscores are nothing, it wouldnt let me format it properly.
THANKS FOR TRYING!

Question 455536: If you could please help me figure this problem out, I would greatly appreciate it:

I found that the vertex is (1,0) but I need to use the vertex to find c.
I tried subbing in the x value from the vertex, but that got me nowhere.

Question 455309: How do you solve domains of functions? For example,
f(x)=square root of (x-2)
f(x)=-5x/7+4
f(x)=1/x-2
There's the domain of f(x), the range of f(x), the equation of f^-1(x), the range of f^-1(x), and whether f^-1(x) is a function. How do I solve for each?
Thanks!

Question 455942: How do I find the center, vertices, co-vertices, and foci of this ellipse x squared+4y squared-2x+16y+13=0? I tried subtracting 13 to both sides then factoring everything else but it doesn't look right. Can someone help me?

Question 456470: I'm pretty sure that trigonometry is needed for this problem, but I'm not totally sure!
The line 3y+x=10 intersects the circle x^2+y^2=50 in two distinct points. Suppose you drew a radius to each of the two points of intersection. Find the angle, in standard position, created by each radius.
Thank you!!!!
