A circle with center
and radius
has equation

If we substitute
in this equation, we have

This equation has two solutions (i.e. the line intersects the circle in two points) if and only if the determinant is greater than zero:

The expression simplifies to

The solutions to the associated equation are

So, the parabola is negative between the two solutions:

Answer:
The fraction of tiles that will be the color of "sand" is 23/60
Step-by-step explanation:
we know that
The sum of the fractions of the tiles must be equal to 1
Let
x ----> the fraction of tiles that will be the color of "sand"
we have that

solve for x
Find the Least Common Multiple of denominators

Multiply both sides by 60

simplify


therefore
The fraction of tiles that will be the color of "sand" is 23/60
26 is the number of the parallelograms that fall into the category A U B. In this universal set, you must likely to find 26 parallelograms that fall into the category A U B. With 4 congruent sides and four congruent angles in set A and B we can see 26 parallelograms that fall into the category A U B.
Answer:
A. sec =12/13×
B. COS =12/13×
C. tan =12/5✓
D. sin =12/13 ✓
Step-by-step explanation:
we know,
using Pythagoras formula,
p=12,h=13 ,b=?
h^2 =p^2 +b^2
b=5
so tan = p/b
=12/5
sin=p/h and cosec= h/p
D. sin =12/13
