Answer:
Any value of x x makes the equation true. All real numbers Interval Notation: ( − ∞ , ∞ )
.
Answer:
It is c = kt.
Step-by-step explanation:
This is direct variation . As the time increases the number of cranes increases.
The equation is c = kt where k is the constant of variation. In this case it will be a positive value because c is increasing with time.
If they make 20 cranes in 10 minutes then we can find the value of k by plugging in these values;
20 = k * 10
g = 20/10
k = 2.
So they make 2 cranes per minute.

Step-by-step explanation:</h2>
The graphs of
can be obtained from the graph of the cosine function using the reciprocal identity, so:

But in this problem, the graph stands for the function:

Because the period is now 4π as indicated and for
in the figure and this can be proven as follows:

Also,
as indicated in the figure and this can be proven as:

Answer:
65 mph
Step-by-step explanation:
Let x mph be Mike's slower rate, then his faster rate is x+10 mph.
1. Mike drove for 3 hours at a slower rate, thus he drove

2. Mike drove for 4 hours ar a faster rate, so he drove

3. In total he drove 495 miles. Hence
