Sketch a graph so you can find the vertex and determine if the parabola is horizontal or vertical. When i graph (-2,4) and then y=6, I find the middle is (-2,5) so that will be the vertex. The distance to the vertex is -1 so 4p=-4.
My formula is (x-h)^2=4p(y-k), now just plug in numbers. You should end up with (x+2)^2=-4(y-5).
Some instructors want you to write (y-k)=1/(4p)(x-h)^2 which is the same thing, so check to see which one you should be using.
To find out if a number is prime you have to find it's factors. if the factors are only 1 and that number it's prime, if the number has other factors then it's composite. hope i helped! have a great day.
Find, days Lydia takes to make 86 bracelets
+ number of bracelets she haven’t made: 86-14=72
+ days it take to Finnish: 72/3=24
So, she needs 24 days to make 86 bracelets
Well, I know that there are 128 ounces in 1 gallon, so
128/2 = 64
There are 64 ounces in 1/2 a gallon. :)
