Answer:
The mean is 17.
Step-by-step explanation:
Answer:
The center is located at (-1, -2), and the radius is 5.
Step-by-step explanation:
The general equation of a circle is given as
(x - a)^2 + (y - b)^2 = r^2
where
a and b are the centre of the circle and r is the radius
Given the equation
x2 + 2x + y2 + 4y = 20
add 1 ad 4 to both sides
x2 + 2x + 1 + y2 + 4y + 4 = 20 + 4 + 1
factorise
(x +1)^2 + (y+2)^2 = 5^2
comparing with the general equation
a = -1, b = -2, r = 5 (all measured in units)
Answer: Option C.
Step-by-step explanation:
Let as consider the complete question is same as question shown in the below figure.
In the figure m║n.
If a transversal line intersect two parallel lines then same sided interior angles are supplementary angles and their sum is 180 degrees.
Divide both sides by 4.
The value of x is 45 degrees.
Therefore, the correct option is C.
U do the PEMDAS P- parenthesis, E- exponents, M-Multiply, D- Divide,
A- Add, S- Subtract u do the math in the order like the PEMDAS and u would get
2,040 hoped it helped!
Basically it would be a compass is used to copy angles haha.
