Answer:
The parametric equations represents an ellipse by the rectangular equation .
Step-by-step explanation:
We proceed to use the following trigonometric identity to derive an expression in rectangular form:
(1)
Where:
and
Then, we expand the expression as follows:
(2)
The parametric equations represents an ellipse by the rectangular equation .
Answer:
1.) 5/1
2.) -7/8
3.) -4/2
Step-by-step explanation:
The formula of slope m=
1.) rise=5 run=1
2.) rise=7 run=-8
3.) rise=4 run=-2
For this case we have that by definition, the area of a rectangle is given by:
Where:
a, b: They are the dimensions of the rectangle.
In the statement we are told that "The area is greater than 12 square inches", then:
Also we have:
Substituting we have:
Dividing between 2 on both sides:
Finally we have:
