<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:

{Note, that BO is a radius of circle and it wasn't necessarily to use Pythagorean theorem to find BO}

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:
<em>5i * 7i = 64</em>
Step-by-step explanation:
<em>i </em>stands for inches, but Ion kno if that's the variable u need. But what I did makes the most sense. But Ion kno if it's right cuz that's my best guess, so y'all don't be gettin mad if it's wrong.
Answer: 1 inches = 6 inches
Step-by-step explanation:
From the question, we are informed that an image of a book shown on a website is 1.5 inches wide and 3 inches tall on a computer monitor and that the actual width of the book is 9 inches.
Based on the above analysis, the scale that is being used for the image is:
= 1.5/9
= 1/6
= 1:6
Therefore, the scale is used is:
1 inches = 6 inches
Stance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(3,5)(7,3)
d = sqrt (7 - 3)^2 + (3 - 5)^2
d = sqrt 4^2 + (-2^2)
d = sqrt 16 + 4
d = sqrt 20
d = 4.47....rounded = 4.5
