Answer:

Option (3)

Step-by-step explanation:

Track is shaped as a rectangle with a semicircle on either side.

Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.

= 2(96) + 2πr

= 192+2\pi (\frac{35}{2})

= 192 + 35π

= 192 + 109.9

= 301.9 m

Since, Jake plans to run four laps.

Therefore, distance covered by Jake = 4 × 301.9

                                                              = 1207.6 m

Option (3) will be the correct option.

A linear relation is modeled by the equation y/x = -3.
Maksim231197 [3]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

The given equation is :

  • \dfrac{y}{x}  =  - 3

now, here

  • y =  - 3x

1. constant of proportionality for this direct variation is :

  • - 3

2. for the given table :

  • x = 0 and y = 0

  • x = 1 and y = -3

  • x = 2 and y = -6

  • x = 3 and y = -9

3. the given equation in slope intercept form will be :

  • y =  - 3x + 0

where, slope (m) = -3 and y - intercept (b) = 0

4. graph is attached in attachment ~
