Answer:

$9x^2+4y^2=36$

Step-by-step explanation:

We are given that

$x=2cos t$

$y=3 sin t$

$0\leq t\leq 2\pi$

$cost=\frac{x}{2}$

$sint=\frac{y}{3}$

$sin^2 t+cos^2 t=(\frac{x}{2})^2+(\frac{y}{3})^2$

$1=\frac{x^2}{4}+\frac{y^2}{9}$

By using the formula

$sin^2\theta+cos^2\theta=1$

$1=\frac{9x^2+4y^2}{36}$

$9x^2+4y^2=36$

How do you solve 26/57= 849/5x

sergeinik [125]

If you would like to solve 26/57 = 849/5x, you can do this using the following steps:

26/57 = 849/5x /*(5x)
26/57 * (5x) = 849 /*57
26 * 5x = 849 * 57 /26
5x = 48393/26 /5
x = 48393/(26*5)
x = 372.25

The correct result would be 372.25.
