A vertical line has an undefined slope... AKA has no slope. So your answer would be D
Answer:
<u><em>A </em></u><u><em>quadratic function </em></u><u><em>is a second degree polynomial function. The general form of a quadratic function is this: f (x) = ax2 + bx + c, where a, b, and c are real numbers, and a≠ 0.</em></u>
First off, a million dollars in pennies is 100,000,000. Let's see:
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 + 1024 + 2048 + 4096 + 8192 + 16384 (HALFWAY POINT) + 32768 + 65536 + 131072 + 262144 + 524288 + 1,048,576 + 2,097,152 + 4,194,304 + 8,388,608 + 16,777,216 + 33,554,432 + 67,108,864 + 134,217,728. This is where I'll stop, because now the penny scenario is more money, but there were still some days left.
The answer is a because when the 8 is by itself it menas it's the y-intercept
Refer to the attached diagram for help.
All radii of a circle are congruent.
Tangent segs LP and LQ are congruent. (Tangent segs drawn to a circle from the same point are congruent)
Because of this we can establish OPLQ as a kite.
OPLQ is a kite implies that OL bis. angle PLQ.
An angle bis. divides an angle into 2 congruent, parts, so angle OLP must be 30 degrees.
Since tangents form right angles with the radius, angle OPL is right.
Now we have a right triangle OPL with a 30-degree angle. The other angle must be 60 degrees because of the no-choice theorem. (180-(30+90)) = 60
We know that OP is 6 because it is a radius of circle O. How do we use that to find OL? Well, we <em>could</em> use trig, but you might recognize this as a special triangle!
The side opposite the 30 degree angle = x
The side opposite the right angle = 2x
So OL must be 12!
