Answer:
550
Step-by-step explanation:
Of means multiply and is means equals
900% * b = 4950
Changing to decimal form
9 b = 4950
Divide each side by 9
9b/9 = 4950/9
b =550
Answer:
x=2
Step-by-step explanation:
4x=8
/4 /4
divide both sides by 4
x=2
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
