Answer:
The correct statement that is used when a scatter plot is constructed is: The independent variable is the input variable and should be represented by the x-axis.
Step-by-step explanation:
The answer is 81/8
Alternative Forms:
10 1/8 or 10.125
Answer:
the answer is -0.95
Step-by-step explanation:
To solve the problem you must know that to change from Cartesian to polar coordinates you must write:
x = rcos (θ)
Where "r" is the radius
Likewise y = rsin (θ)
Therefore, in the expression r = 3cos (θ) one can write r as:
r = x / cos (θ)
So:
x / cos (θ) = 3cos (θ)
x = 3cos ^ 2 (θ)
The same for y ...
y = rsin (θ)
y = 3cos (θ) sin (θ).
Finally the correct answer is option 2.
x = 3cos ^ 2 (θ) y = 3cos (θ) sin (θ).
