Given the parametric equations x = 2sint and y = -3cost on 0 ≤ t ≤ π. convert to a rectangular equation and sketch the curve
Temka [501]

The rectangular equation for given parametric equations x = 2sin(t) and   y = -3cos(t) on 0 ≤ t ≤ π is  \frac{x^{2} }{4} +\frac{y^2}{9} =1 which is an ellipse.

For given question,

We have been given a pair of parametric equations x = 2sin(t) and           y = -3cos(t) on 0 ≤ t ≤ π.

We need to convert given parametric equations to a rectangular equation and sketch the curve.

Given parametric equations can be written as,

x/2 = sin(t) and y/(-3) = cos(t) on 0 ≤ t ≤ π.

We know that the trigonometric identity,

sin²t + cos²t = 1

⇒ (x/2)² + (- y/3)² = 1

⇒ \frac{x^{2} }{4} +\frac{y^2}{9} =1

This represents an ellipse with center (0, 0), major axis 18 units and minor axis 8 units.

The rectangular equation is  \frac{x^{2} }{4} +\frac{y^2}{9} =1

The graph of the rectangular equation \frac{x^{2} }{4} +\frac{y^2}{9} =1 is as shown below.

Therefore, the rectangular equation for given parametric equations x = 2sint and y = -3cost on 0 ≤ t ≤ π is  \frac{x^{2} }{4} +\frac{y^2}{9} =1 which is an ellipse.

2n + 3 = -3.2 what is the answer to n
Vlad1618 [11]

Answer:n=-3.1

Step-by-step explanation:

2n + 3 = -3.2

Subtract 3 on both sides

2n+3-3=-3.2-3

2n=-6.2

Divide 2 on both sides

2n/2=-6.2/2

n=-3.1

What is the value of x in the equation is 4+6x=-3+7x​
Anvisha [2.4K]

Answer:

x=1

Step-by-step explanation:

  1. choose a side to get rid of so since its easier to take 6 away from seven we will do that but remember what you do to one side you have to do to the other
  2. so take away 6x from the left that leaves 0 your equation should look like this 4=-3+7x remember that we have to to it to the right side too
  3. so take 6x away from the 7x on the right side and that leaves 1x so it should look like this 4=-3+1x
  4. then since it's a -3 you will need to add 3 for it ton equal 0 so it will look like this 4=7x
  5. but dont for get to do the same to the other side so add 3 to the 4 on the left so it will look like this 7=7x
  6. then divide by 7 to get x by itself so it will look like this 7=x
  7. but you aren't done yet you still have to divide the left by 7 so it will look like this 1=x

and thats all there is to it hope this helps
