There is a formula for this:

Total Time = (worker1 * worker2) / (worker1 + worker2)

(3 * 8) / (3 + 8)

24 / 11 =

2.1818181818 hours

A goat is tethered to a stake in the ground with a 5-m rope. The goat can graze to the full length of the rope a full 360 degree

Nina [5.8K]

The length of the rope in this case becomes the radius of the circle that the goat is able to graze. The area of the circle is calculated through the equation,
A = πr²
Substituting,
A = π(5m)² = 78.54 m²
Thus, the area that the goat is able to graze is equal to 78.54 m².

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (2, 3)

Point (2, -6)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

Substitute [SF]: $m=\frac{-6-3}{2-2}$
Subtract: $m=\frac{-9}{0}$
Define: m = undef
