(csc x-1)(csc x+1)=csc²x-1²=csc²x-1=(1/sin x)² -1=1/sin x² - sin²x/sin²x=
=(1-sin²x)/sin² x = cos² x/ sin² x = (cos x/sin x)²= (cot x)²
Multiply each number by 10. The constant of proportionality is 10. You can do it!!
So the fliping over the y-axis you would count how many spaces it is to the y-axis then count that many on the other side do the same with all three points. for the x-axis do the same as you did for y. for rotating it 90 degrees clockwise you would flip the numbers of your coordinates other points and swap the x sign
example: -5,-6 it is now -6,5 or if you had -4,6 it is now 6,4
(2x)^2+2(2x)(7)+7^2
(2x+7)^2
Answer:
9 cakes
Step-by-step explanation:
If each of the 17 people will eat 1/2 of a cake, you would 17*1/2 cakes. This is 17/2, or 8.5. You cannot usually order 8.5 cakes, so you would round up. 9 cakes.
