Answer: 1. What are the focus and directrix of a parabola? Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).

2.The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle.

aev [14]

Answer:

16 cups of formula

Step-by-step explanation:

you take 16 (the amount of bottles) and multiply it by 4 (the amount one bottle holds)

which gets you 64 then you multiply that by 2 ( the amount of children)

which gets you 128

then you divide by 8, because there are 8 fl oz in a cup

which gets you 16

You are hiking and are trying to determine how far away the nearest cabin is which happens to be due north from your current pos

elixir [45]

Answer:

469.60 yards far away is the cabin to the nearest yard

Step-by-step explanation:

given data

walks = 215 yards

bearing on the cabin = N 24.6 degrees E

solution

we know here when 2 line are parallel then opposite angle are equal

so here $\angle$ DAC =

and now we take here triangle ABC

so here we can say

tan (24.6 ) = $\frac{AB}{BC}$

so here BC will be

BC = $\frac{Ab}{tan(24.6)}$

put here value and we get

BC = $\frac{215}{tan(24.6)}$

solve it we get

BC = 469.60 yards
