√44=(√4)(√11)=2(√11)=2√11
Answer:
First, plug-in x and y as 3sinθ-2 and 3cosθ+4 into the equation, respectively:
Then, +2 and -2 cancel out and +4 and -4 cancel out as well, leaving you with:
We can factor out 3^2 = 9 from both equations:
We know from a trigonometric identity that , meaning we can reduce the equation to:
And therefore, we have shown that (x+2)^2 + (y-4)^2 = 9, if x=3sinθ-2 and y=3cosθ+4.

Answer:
All the 3 choices are correct.
Step-by-step explanation:
11:5 11 divided by 22 is 1/2 and 5/10 is 1/2
110/50 110 divided by 22 is 5 and 50 divided by 10 is 5
33/15 33 divided by 22 is 1 1/2 and 15 divided by 10 is 1 1/2
Answer:
1. figure 4 ; 2. figure 1; 3. figure 3 .
Step-by-step explanation:
1. The correlation coefficient is closest to 1 for the data-set relating to figure 4.
2. The least evidence of a linear relationship is shown by the data-set relating to figure 1.
3.The correlation coefficient r appear to be equal to -1 for the data-set relating to figure 3.
We know that as more the modulus of the correlation coefficient (r) approaches 1, more the figure related to the data-set starts to resemble a straight-line.
The line of linear regression takes a positive slope for a positive value of r and takes a negative slope for a negative value of r.
Moreover, more the modulus of r approaches 0, more there is absence of linearity in the scatter plot.
