Answer:x=7
Step-by-step explanation:
Here AD=6
AB=6 (tangents drawn from external point to a circle are equal)
Then BC=13-6=7
Now, CE=BC=7(tangents drawn from external point to a circle are equal)
EF=14-7=7
EF=FG=x=7(tangents drawn from external point to a circle are equal)
1)
a) Draw the axis:x-axis is horizontal, y-axis is vertical
b) draw a point on any part of the plane (use color to highlight it)
c) draw a second point on a different part of the plane (again use color)
d) draw the straight line that passes through the two points (use a ruler).
That is it.
2)
a) Draw the axis: x-axis is horizontal and y-axis is vertical
b) Draw a stright line (use a ruler)
c) Draw a second straight line (use a ruler) which is not parallel to the first line. Extend the second line intil it intersects (and passes) the first line. The lines can only intersect in one point (if the lines are parallel they will not intersect each other).
Answer:
D=(-infinity, +infinity)
R=(-infinity, 4]
Step-by-step explanation:
I think that 2 is an exponent so you function is f(x)=-3(x-5)^2+4
So if this is the case this is a parabola open down when a vertex of (5,4).
Visualize or draw a rough picture of that because that is all you need to answer this question.
The domain for a parabola function is always all real numbers (do notice I said parabola function).
The range for this parabola is (-infinity, 4] since open down and the highest point has y value 4.
Pi = circumference/diameter
