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
Note: Consider we need to find the vertices of the triangle A'B'C'
Given:
Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.
Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).
To find:
The vertices of the triangle A'B'C'.
Solution:
If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then
Using this rule, we get
Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).
