Answer:
Step-by-step explanation:
Rectangle:
Length : Width = 3 : 5
Length = 3x
Width = 5x
Perimeter = 64
2*(length + width) = 64
2*(3x + 5x) = 64 {Add like terms}
2 * 8x = 64
16x = 64 {Divide both sides by 16}
x = 64/16
x = 4
Length = 3*4 = 12 units
Width = 5*4 = 20 units

The center is 3, -1 and the radius is 2 I believe.
Since the formula is (x-h) ^2 + (y-k) ^2 = r^2, the radius here is already squared so 2 would be the radius. The center would be the h and k and since the k is positive, that means it's negative as the sign has been flipped.
Hope this helps!
Answer:
4/3 or 1.34
Step-by-step explanation:
2/3 ÷ 6/12
= 2/3 × 12/6
= 4/3 or 1.34
Answer:
Symmetric with respect to the polar axis in agreement with the second answer listed.
Step-by-step explanation:
This is the shape of a cardioid it contains the function cosine of the angle so it must be symmetric with respect to the polar axis, since the cosine function is also symmetric for positive and negative values of the angle.
