Answer:

sin 60° = 0.9

Step-by-step explanation:

sin 60° = cos 30°

cos 30° = 0.866025403

0.866025403 to one significant figure

0.866025403 ~ 0.9

~. means approximately.

therefore sin 60° = cos 30°

sin 60° = 0.9

Sedbober [7]

Answer:

The slope of the equation is -3.          

Step-by-step explanation:

Given : Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each minute.

To find : What is the slope ?

Solution :

Let x be the number of minutes taken to dig the ground.

He started digging his way deeper into the ground, descending 3 meters each minute i.e. '-3x'

Let y is the total distance travel to dig the ground.

Mr. Mole's burrow lies 5 meters below the ground.

The equation form is y=-3x-5

Comparing with general slope form i.e. y=mx+c where m is the slope.

The slope of the equation is -3.
