Answer:
(x+1)^2 + (y+1)^2 = 49
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x- -1)^2 + (y- -1)^2 = 7^2
Simplifying
(x+1)^2 + (y+1)^2 = 49
Answer:
area of the trapezoid=1/2(7+12)×5
=47.5cm
Answer:
x(1+x+x^2)
Step-by-step explanation:
If the function is:
f (x ) = 5 ( x +2 ) / ( 3 ( x-1 ) ( x - 7) then for: f ( x ) = 0
5 ( x + 2 ) = 0
x + 2 = 0
x = -2
Answer: E ) -2 ( only )
Answer:
negative association
Step-by-step explanation:
This diagram is a scatter plot which represents a set of data. Data on a scatter plot can fit one of three descriptions: positive (increasing), negative (decreasing) or no association (points do not form any kind of line). Given this data and the line of best fit, or the line that pass through the majority of the points, it is a decreasing line. Since the line goes downhill, it is a negative association.
