Answer:
A general line can be represented as , y= m x + c
And general equation of circle is , ax²+by²+2 g x +2 f y +c=0
Now there are following possibilities
1. A line and circle have no common point of intersection, that is no solution.
2. A line may be a tangent to a circle, that is one common point, one solution.
3. A line may intersect a circle maximum at two points, that is 2 solution.
Image is depicted below.
So a hack is we know that 20% times 5 =100% and 40 divided by 2=20 so
50=40%
divide both sides by 2
25=20%
20 times 5=100 so
multiply both sides by 5
125=100%
Answer:
B
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° =
, then
cos45° =
=
=
( cross- multiply )
c = 3
it is 11.25................................
Answer:
C) 72 square yards
Step-by-step explanation:
I cut it into two shapes. One being the rectangle on top with values 12 yd and 3 yd. the other being the square 6yd by 6yd
12•3= 36
6•6= 36
36+36= 72
72 square yards
hope this helps chu luv <3
