Luci cuts a board that is 5/7 yard long into pieces that are 5/14 yard long. How many pieces does she cut?

zvonat [6]

Answer:

So total number of pieces will be 2

Step-by-step explanation:

We have given the total length of the board $=\frac{5}{7}yard$

It is given that Luci cuts the board into pieces of $=\frac{5}{14}yard$ long

We length of each piece = $=\frac{5}{14}yard$

We have to find the total number of pieces

For finding total number of pieces we have to divide the total length of board by length of each piece

So number of pieces $=\frac{\frac{5}{7}}{\frac{5}{14}}$ = 2

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:

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