Sin²t +cos²t =1
<span> x=2+3 sin t
sin t=(x-2)/3
</span><span>y=1-1/2cos t
y-1= - (cos t)/2
cos t =-(y-1)/(1/2)
</span>(x-2)²/3² + (y-1)²/(1/2)² = 1

Answer:
270 Markers
Step-by-step explanation:
5 x 54 = 270
(sorry if I'm wrong)
To find the mean, you add all of the numbers up and then divide by how many numbers there are. Mean is also known as the average. To find the medium, you have to list all the numbers in order then cross them out to find the middle. To find the mode, you find how many numbers are the same and count the number with the most repeats.
Ex for mean.) 5 + 2 + 5 = 15. 15/3 because there are 3 numbers in the equation. 15/3 = 5. The mean is 5.
Ex for median.) 1 2 2 3 4 5 7 9 9. 4 is in the middle so it is the median.
Ex for mode) 34 35 34 34 32 7. There are more 34s than any other number so 34 is your mode.
There is only one solution x=2.
9p + 3p and 2 -2 that is it
