Answer:
Step-by-step explanation:
6 x 20 = 120
10 - 6 = 4 and (8+6) - 20 = 6
(4 x 6) / 2 = 12
120 + 12 = 132
Answer:
( x - 2 )^2 + ( y - 1 )^2 = 1
Step-by-step explanation:
As i previously explained,
The general form of equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2.
h and k are the co-ordinates of the center of circle and r is the radius
Here, We have (2,1) as the co-ordinates of the center of circle
Now,
( x - h )^2 + ( y - k )^2 = r^2
or,( x - 2 )^2 + ( y - 1 )^2 = r^2
The radius of the circle is 1 units(from figure)
So, put that in, we get
( x - 2 )^2 + ( y - 1 )^2 = 1^2
or, ( x - 2 )^2 + ( y - 1 )^2 = 1
You can simplify this or leave it here.
Answer:
CD and DE are perpendicular because their slopes are -1/3 and 3
Step-by-step explanation:
Perpendicular lines will always have the opposite reciprocal.
Answer:
Step-by-step explanation:
We know that we'll have to manipulate the equation , so we can start there.
stands for the gradient of the function (or slope) and stands for the y-intercept of the function (the y value where the line touches the vertical line (y axis)).
Since we know that stands for the slope and that the slope in this problem is 5, we can plug it into the original equation and we'll get
We also know that this line passes through the point (4,24). This means that it passes through the point where x = 4 and y = 24. If we plug in these values into the equation that we made above, we can solve for b.
Now that we know what b is, we can plug it into and we'll get
Good luck!
