Answer:
D. (-x+5)^2/9+(y-4)^2/4=1 (I assume there was a mistype)
Step-by-step explanation:
The first step is isolating the sine and cosine functions.
x=5-3cos(t)
x + 3cos(t) = 5
3cos(t) = 5 - x
cos(t) = (5 - x)/3
y=4+2sin(t)
y - 4 = 2sin(t)
(y - 4)/2 = sin(t)
Then, square at both sides of the equal sign
cos²(t) = (5 - x)²/3² = (5 - x)²/9
sin²(t) = (y - 4)²/2² = (y - 4)²/4
Recall the trigonometric identity and replace.
cos²(t) + sin²(t) = 1
(5 - x)²/9 + (y - 4)²/4 = 1

Step-by-step explanation:
<span>You can share a 6 segment chewy
fruit worm by giving the four people 1 ¼ segments. Also, there are a lot ways
on how to divide it equally, but in this case, I’ll show two. Here are the two ways on how to share it:
1. You can divide the worm by giving one segment for each and then divide the remaining two segments in halves, thus resulting to having </span><span>1 </span>¼ shares.
2. Cut the worm in a horizontal manner. In this way, you'll have 12 segments now. You can then proceed by distributing the share by 3s, which is still equivalent to 1 <span>¼</span>.
Total surface area is 152 cm
