Answer:
Option A is correct
Step-by-step explanation:
Answer:
140 square inches
Step-by-step explanation:
An 8 inch by 6 inch rectangle would have a lateral area of 140 square inches.
Given two points, say points
A and
B, we can use the slope formula to find the slop of the line:
If
A has coordinates of
(w,c) and
B has coordinates of
(y,z), we can find the slope.
}{y-w} [/tex]
Now we can say that we can use the point slope form formula:
Now we can substitute
m for the slope, and use any points to plug in
and
.
Hope this helps! :^)
Step-by-step explanation:
x² + y² + 2x + 6y = 39
( x + 1)² - 1 + ( y + 3)² - 9 = 39
( x + 1)² + ( y + 3)² - 10 = 39
(x + 1)² + (y + 3)² = 49
radius= √49 = 7
center = ( -1 , -3)
x² + y² - 4x - 2y + 1 = 0
(x - 2)² - 4 + (y - 1)² -1 + 1 = 0
(x - 2)² + (y - 1)² = 4
radius = √4 = 2
center = (2 , 1)
