Below are the choices and the answer for me is A.
a. The lengths of the sides and the measures of the angles are preserved, so the triangle are congruent
b. The lengths of the sides are enlarged and measures of the angles are preserved, so the triangles are similar.
c. The lengths of the sides change and the measures of the angles change as well, so the triangles look nothing alike.
d. The lengths of the sides are reduced and measures of the angles are preserved, so one triangle is reduction of the other.
Answer:
1. cos (x/2)
2.y=cos(4x)
3. y=cos(x)
4.y= cos(x/4)
Step-by-step explanation:
The graph of cosine function is sinusoidal and the y value ranges between -1 to 1.
the cosine function is periodic with general period P of 2π
if P< 2π then cosine graph experience a compression horizontally
if P>2π then cosine graph experience a stretch horizontally
for graph 1, the period is 4π hence the graph is stretched with period of 4π
for graph 2, the period is π/2 hence the graph is compressed with period of π/2
for graph 3, the period is 2π hence the graph is periodic with period of 2π
for graph 4, the period is 8π hence the graph is stretched with period of 4π
!
Left side angle = 180-150-12 = 18 degrees
10 / sin 12 = c / sin 18
c = 10 * sin 18 / sin 12
c = 14.9 cm to nearest tenth
' n ' the 'n'th term
1 4
2 2
3 0
4 -2 .
In general, the 'n'th term of the sequence is A(n) = 6 - 2n .
Answer:
False
Step-by-step explanation:
H=8
8-2>6
Simplify
8-2=6
6>6
It should be 6=6
