Answer:
Option: B is the correct answer.
B. 1
Step-by-step explanation:
We know that:
Tangent to a circle is a line that just touches the circle or in other words we may say that it touches the circle at exactly one point.
Here by looking at the figure we see that there is a circle inside the other circle and meets at exactly one point.
Hence, now for such a figure there exist just one tangent that passes through the two circle at the point of intersection of the two circles.
Hence, option: B is correct.

For n=3,θ =
Answer:
The required expression is
Step-by-step explanation:
Consider the provided information.
National Textile installed a new textile machine in one of its factories at a cost of $250,000.
That means for 0 year the cost of the machine is $250,000.
This can be written as: (0, 250,000)
Over 10 years with a scrap value of $10,000
That means for 10 year the cost of the machine is $10,000.
This can be written as: (10, 10,000)
Now first find the rate of change:
Rate of change=m=
Rate of change=m=
Rate of change=m=
Now use the point-slope form of an equation of a line with the point (0, 250,000), we can find the required expression.
Hence, the required expression is
