I wish you cloud ok right
Yeah
Answer:
0.1218
Step-by-step explanation:
Δ ABC and Δ A'B'C' are congruent.
Proof: BC = B'C' = 5 units (given)
Angle B = Angle B' = 72° (given)
Angle C = Angle C' = 32° (given)
The 2 tringles are ten equal ASA
Te x intercepts are where the graph crosses the x axis or wher y=0
the y intercept is where the graph crosses the y axis or where x=0
to find vertex, here is a hack
the x coordinate of the vertex for an equation in form ax^b+bx+c=y is -b/2a
so
y=3x^2+12x+7
-b/2a=-12/2(3)=-12/6=-2
sub that back
y=3(-2)^2+12(-2)+7
y=3(3)-24+7
y=9-17
y=-8
vertex is (-2,-8)
intercepts
x intercept is where y=0
0=3x^2+12x+7
using quadratic formula
x=(-6-√15)/3 and (-6+√15)/3
xints at ((-6-√15)/3,0) and ((-6+√15)/3,0)
yint is where x=0
set x=0
y=7
yint is at y=7 or (0,7)
vertex at (-2,-8)
xints at x=
and
or at the points
and
yint at y=7 or at (7,0)
