The figure shows an aerial view of a playground. If David runs around the field three times, he covers a distance of_____yards.

Andrew [12]

For this case, what we must do is find three times the perimeter of the figure.

The length of the arch is given by:

$s = r * \alpha$

Where,

r: radius of the circle

alpha: central angle in radians

We have then:

$s = 35 * (\frac{280}{180}) * \pi\\s = 171 yards$

Then, the perimeter of the figure is:

$P = 3 * (171 + 45)\\P = 648 yards$

Answer:

If David runs around the field three times, he covers a distance of 648 yards.

A student claims that 3x + 2y = 5xy. Use a visual representation to show whether this is true or false

Ket [755]

Answer:

It is true, except when x = 2/5, since it is an asymptote.

Step-by-step explanation:

3x=5xy-2y

3x=y(5x-2)

3x/5x-2=y

5x-2=0 -------> 5x=2 --------> x=2/5
