Find the focus of a parabola with a = 150 1/4.
so a = 1/4c
150 1/4 = 1/4c
I need help solving this for c.

Answer 1

Ok well \[\Large \frac{1}{4}c=\frac{c}{4} \]

Answer 2

And the opposite operation of division is ?

Answer 3

multiplication. so i ignore the 150 for now?

Answer 4

Well no. Is the 150 1/4 actually \[\Large 150\frac{1}{4}~or~150.25?\]

Answer 5

Like is that what number it is or is it just hte question number, question #150

Answer 6

150 1/4

Answer 7

Ok well you gotta convert it to an improper fraction, do you know how to do that?

Answer 8

150 times 4 add 1

Answer 9

Ok, and that gives you \[\Large \frac{601}{4}\]

Answer 10

Now you're gonna multiply 4 by both sides to get c by itself

Answer 11

okay

Answer 12

601 = 1/c

Answer 13

Remember it was c/4 so multiplying both sides by 4 would have a 4 in the numerator and denominator and they cancel out adn you're left with
c=601

okay, thank you!!
