Answer:
First, plug-in x and y as 3sinθ-2 and 3cosθ+4 into the equation, respectively:
Then, +2 and -2 cancel out and +4 and -4 cancel out as well, leaving you with:
We can factor out 3^2 = 9 from both equations:
We know from a trigonometric identity that 
, meaning we can reduce the equation to:
And therefore, we have shown that (x+2)^2 + (y-4)^2 = 9, if x=3sinθ-2 and y=3cosθ+4.
Hope this helped you.
Answer:
11253.76
Step-by-step explanation:
To find the volume of a cylinder we must utilise the volume of cylinder formula which is
→ Volume of cylinder = π × r² × h
Where 'r' is the radius and 'h' is the height so let's start substituting in the values,
→ Volume of cylinder = π × r² × h
⇒ Substitute in 3.14 for π, 14 for 'h' and 16 for 'r'
→ Volume of cylinder = 3.14 × 16² × 14
⇒ Simplify
→ Volume of cylinder = 11253.76
So a cylinder has a height of 14 millimetres and a radius of 16 millimetres has a volume of cylinder 11253.76 inches³
50^2= 50x50
50x50=2500
2500*5= 12500
For every person that walked there were 12 who drove and if the 270 made the trip then 87 walked
Answer:
3
Step-by-step explanation:
The question gives you the x coordinate, so plug in x with 3.
y=4(3)-9
y=12-9=3
y=3
(3,3)
