X=rcos(t), y=rsin(t). so y/sin(t) = r => csc(t) = r/y. so for now we have r*(r/y)=8. To solve for r, do x^2 + y^2 = r^2, so r=sqrt(x^2 + y^2). So we have sqrt(x^2 + y^2<span>)*(sqrt(x^2 + y^2<span>)/y</span>)=8, or (x^2+y^2)/y = 8, or x^2/y + y = 8.</span>
Answer:
19) -2/5 20) 1/2 21) -5x 22) Slope is 0 23) undefined slope 24) Slope is 0 25) Slope is undefined 26) Slope is undefined
Step-by-step explanation:
You can use Y2-Y1/X2-X1 to get the answer
For example, for 19,
(5,0) (0,2)
X1 Y1 X2 Y2
2-0/0-5
2/-5
-2/5
10,000 of the endangered birds would be left
I’m guessing it’s 49 but I’m probably wrong sorry
