Answer:
Step-by-step explanation:
We can treat this as a units conversion problem. Each multiplier is a fraction that has the same value in the numerator as the denominator, but expresses that value with different units. We choose to cancel units we don't want, and replace them with units we do want. Ultimately, we're evaluating the expression ...
time = quantity/rate
(4 mi²) × (640 ac/mi²) × (5 min)/(2.5 ac) × (1 h)/(60 min)
= (4·640·5)/(2.5·60) h = 85 1/3 h
It will take about 85 hours to plant the farm.
__
At 8 hours per day, that is (85 1/3)/(8) = 10 2/3 days.
It will take about 11 days to plant the farm.
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

Answer:
8
Step-by-step explanation:
The problem statement tells you ...
17/4 +6n = 7n -15/4
Subtract 6n -15/4:
32/4 = n = 8
The number is 8.
_____
<em>Check</em>
17/4 +6(8) = 7(8) -15/4
4 1/4 +48 = 56 -3 3/4
52 1/4 = 52 1/4 . . . . . . answer checks OK
14/2 = 7
35/7 = 5
x=5
hope this helps
Answer:
115°
Step-by-step explanation:
