Step-by-step explanation: Write the equation of the circle using h = 2, k = –1, and r = ... (x – 1). 2. + y. 2. = 4 is a circle with center (1, 0) and a radius of 2.
Answer:
-5
Step-by-step explanation:
Answer:
Answer should be 5
Step-by-step explanation:
+ <span>The vertex of a parabola is (3,2),
that means the parabola's equation is y=a(x-3)</span>²+2
+ <span>A second point on the parabola is (1,5) and we replace x=1 and y=5. We have:
5</span>=a(1-3)<span>²+2 , so we have 4a=5-2 or a=3/4
So the equation is y=3/4 (x-3)</span>²+2
And by checking we have the point (5;5) is on the parabola

The main advantage with boxplots (aka box and whisker plots) is that we can spot the five number summary very quickly. The five number summary consists of these items:
- Min
- Q1 = first quartile
- Median (sometimes referred to as Q2)
- Q3 = third quartile
- Max
The min and max are the left-most and right-most tips of the whiskers, assuming there aren't any outliers. They are the smallest and largest items.
The left and right edges of the box represent Q1 and Q3 in that order. The vertical line inside the box is the median. The vertical line does not have to be at the exact center of the box.
