Eliminate the parameter,t, in the parametric equation, x=6cos t, and y =3 sin t

german

X = 6 cos(t)
y = 3 sin(t)

we can rewrite these equations as:

$\frac{x}{6}=cost(t) \\ \\ \frac{y}{3} =sin(t)$

Taking squares of both equations we get:

$( \frac{x}{6})^{2}=sin^{2} (t) \\ \\ 
( \frac{y}{3})^{2}=cos^{2}(t)$

Adding both the equations, we get:

$\frac{ x^{2} }{36}+ \frac{ x^{2} }{9}=sin^{2}(t)+cos^{2}(t) \\ \\ 
 \frac{ x^{2} }{36}+ \frac{ x^{2} }{9}=1$

Solve the system. 4x−y=−3y=5x

alina1380 [7]

Answer:

4x - y = -3y = 5x

Write as a system

4x-y = 5x

-3y = 5x

Simplify the expressions

-x-y = 0

-5x-3y = 0

Multiply both sided by -5

5x + 5y = 0

-5x - 3y = 0

2y = 0

y = 0

Substitute the value of y into the equation

-x-0= 0

x=0

A possible solution is (x,y) = (0,0)

Step-by-step explanation:

Total: 65+110+75 = 250

P(O) = 75/250 × 100 = 30%

P(A) = 110/250 × 100 = 44%

P(K) = 65/250 × 100 = 26%
