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).
Answer:
Step-by-step explanation:
For this case we need to define some notation:
represent the remaining length of the candle in inches
represent the time in hours that have elapsed since the candle was lit.
For this case we assume that L and f are related so then we can write this like that: L is a function of t.
And for this case we have a constant rate given of:
And we know a initial condition
So then since we have a constant rate of change we can use a linear model given by:
Where m is given and we need to find b. If we use the initial condition we have this:
And solving for b we got:
So then our lineal model would be given by:
