Let's solve ~
Equation of directrix is : y = 1, so we can say that it's a parabola of form : -
- h = x - coordinate of focus = -4
- k = y - coordinate of focus = 5
- a = half the perpendicular distance between directrix and focus = 1/2(5 - 1) = 1/2(4) = 2
and since the focus is above the directrix, it's a parabola with upward opening.
f(X)=3/x-1,g(x)=2/x
g.f(-5)=g(f(-5))=g(-3/5-1)=g(-3-5/5)=g(-8/5)=2×(-5/8)=-5/4

Answer:
<h3>A). AC is congruent to XZ </h3>
<em><u>Given </u></em><em><u>-</u></em><em><u> </u></em> angle X = angle A
angle Z = angle C
<em><u>To </u></em><em><u>find </u></em><em><u>-</u></em><em><u> </u></em>criteria of congruence
<em><u>Solution </u></em><em><u>-</u></em><em><u> </u></em>
In triangle BAC and triangle YXZ
angle X = angle A
angle Z = angle C
we need one pair of side to be comgruent to show the following traingles congruent
if AC is congruent to XZ
then by angle side angle criteria of triangle both the triangles are congruent..
0.4 per 1 minute = 0.4/1.
