Answer:
r = 2. The center is at (0, 3).
Step-by-step explanation:
Compare the given x ^ 2 + (y - 3) ^ 2 = 4 to the standard equation
(x - h)^2 + (y - k)^2 = r^2.
It becomes obvious that h = 0, k = 3 and r = 2. The center is at (0, 3).
The given equation is in the point-slope form. The slope can be obtained by simple identification of the parts of the equation. This is shown below:
Given equation:
(y - 3) = -2 (x - 4)
y - y1 = m(x - x1)
Where slope, m = -2
The slope of a line perpendicular to the line CD is the negative reciprocal of the slope of the line CD. Therefore:
Slope = 1/2
Answer:
A = 62.35 cm²
Step-by-step explanation:
Use the area formula A = , where a is the side length.
Plug in the values:
A =
A =
A = 62.35 cm²
A rational number is a number that can be written in form a/b where a and b are integers and b is not eual to 0
simplify eacy
we get
is irrational
since we can't write
as a rational number, the entire phrase is irrational
anwer is irrational
If the line containing the coordinate "k", is parallel to the line at 5,5 and 1,-4, then their slopes must be the same, since parallel lines, have the same slope, let's check both slopes then.
