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:
Step-by-step explanation:
At <em>y</em>(0) = 10, when <em>t</em> = 0, <em>y</em> = 10.
Hence, the solution is
a
1.A by SSS axiom
2.F as angle A is 62*
Answer: 1/4 is the answer
Step-by-step explanation: it is 1/4 because 25/100 = 1/4
may i have brainiest plz i have like 1 or something
