ANSWER:
- [ 12 / ( x - y ) ]
STEP-BY-STEP EXPLANATION:
= 12 / ( y - x )
= 12 / - ( x - y )
= - [ 12 / ( x - y ) ]
<span>Point B has coordinates (3,-4) and lies on the circle. Draw the perpendiculars from point B to the x-axis and y-axis. Denote the points of intersection with x-axis A and with y-axis C. Consider the right triangle ABO (O is the origin), by tha conditions data: AB=4 and AO=3, then by Pythagorean theorem:
</span>

.
</span>
{Note, that BO is a radius of circle and it wasn't necessarily to use Pythagorean theorem to find BO}
<span>The sine of the angle BOA is</span>

Since point B is placed in the IV quadrant, the sine of the angle that is <span> drawn in a standard position with its terminal ray will be </span>

Answer:
The product = 7
Step-by-step explanation:
7/8 * 8 = 7
(Multiplying a fraction by its denominator cancels the denominator out)
It's dividing by 2.
Next 3 would be: 25, 25/2, 25/4 or converting those into decimals.
