Answer:
200
Step-by-step explanation:
12km in 240min = 0.05 km per minute
10÷0.05 =200

Answer:
Explicit formula is an = 64(-3/4)^(n-1).
Step-by-step explanation:
Looks like a geometric sequence with a negative common ratio.
-48/64 = - 3/4
36 / -48 = -3/4
Now -27/36 = -3/4 so I think there's a typo in the question. Its -27 not -17.
The required formula is 64(-3/4)^(n-1) .
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

You would multiply 6.5 times 4/13 and then add that to 6.5 to know the amount of uncooked rice you need so...
6.5x4/13=2
2+6.5=8.5
