True or false it will be true
Hi there, a²/3=1/3a², Therefore, the answer is 1/3a²
I think you would have to divide by 2 1/2
43 3/4
_______
2 1/2
Answer: 17 1/2
To check: 17 1/2 × 2 1/2 =43 1/2
Answer:
1244.07
Step-by-step explanation:
Answer:
Solution : Option D
Step-by-step explanation:
The first thing we want to do here is isolate the cos(t) and sin(t) for both the equations --- ( 1 )
x = - 3cos(t) ⇒ x / - 3 = cos(t)
y = 4sin(t) ⇒ y / 4 = sin(t)
Let's square both equations now. Remember that cos²t + sin²t = 1. Therefore, we can now add both equations after squaring them --- ( 2 )
( x / - 3 )² = cos²(t)
+ ( y / 4 )² = sin²(t)
_____________
x² / 9 + y² / 16 = 1
Remember that addition indicates that the conic will be an ellipse. Therefore your solution is option d.
