Which equation in rectangular form describes the parametric equations x=2-3 cos t and y=1+4 sin t?

liraira [26]

Answer:

The parametric equations represents an ellipse by the rectangular equation $\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1$ .

Step-by-step explanation:

We proceed to use the following trigonometric identity to derive an expression in rectangular form:

$\cos^{2} t + \sin^{2} t = 1$ (1)

Where:

$\cos t = \frac{2-x}{3}$ and $\sin t = \frac{y-1}{4}$

Then, we expand the expression as follows:

$\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1$ (2)

The parametric equations represents an ellipse by the rectangular equation $\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1$ .

Use technology to solve for x. 3^x - 4= 6x - 7

Anuta_ua [19.1K]

Answer:

$x=1,1$

Step-by-step explanation:

$3x^2 - 4= 6x - 7$

For the given equation :

Making the coefficients of x to L.H.S

$3x^2-6x-4+7$ $=0\\$

$3x^2-6x+3=0$

Taking 3 as common from the above equation

$x^2-2x+1=0$

Splitting the equation to make factors

$x^2-x-x+1=0$

Taking common from the equation:

$x(x-1)-1(x-1)\\(x-1)(x-1)=0$

Equating 'x' to zero

$x=1,1$
