Answer:

answer of your questions

Step-by-step explanation:

The process of obtaining the equation is similar, but it is more algebraically intensive. Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2.

How do you do this (-4,6) and (3,-7) to find the distance between each pair of points

poizon [28]

You use x1-x2 over y1-y2
So -4-3 = 1 and 6- -7 is 1 so it’s 1/1. That’s the slope.

My name is Ann [436]

Answer:

Solutions given;

Using cosine rule

b²=a²+c²-2*a*c*cos B°

b²=15²+8²-2*15*8*cos39

b²=102.48

b= $\sqrt{102.48}$

b=10.12

b=10.1

Using sine rule

$\frac{sin A}{BC} = \frac{sin B}{AC} =\frac{sin C}{AB}$

$\frac{sin 29°}{15} =\frac{sin C}{8}$

Doing criss cross multiplication

Sin C= $\frac{sin 29°}{15} ×8$

m<C=Sin -¹(0.29)

m<C=14.98

m<C=15°is a required answer.
