Answer:

-(√105)/11

Step-by-step explanation:

Tangent is the ratio of sine to cosine. When tangent is positive, sine and cosine have the same sign. This means the appropriate choice will be either the first one or the last one.

cos(θ) = -√(1 - sin(θ)²) . . . . in the 3rd quadrant

... = -√(1 - (-4/11)²)

... = -(1/11)√(121 -16)

... = -(√105)/11 . . . . . . matches the first selection

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.

What is the value of the product of -20/48 times 6 in simplified form

KATRIN_1 [288]

-20/48 x 6 = $\frac{-20}{48}$ x $\frac{6}{1}$

I would cancel out the 6 in the numerator and the 48 in the denominator
Now I have <u /> $\frac{-20}{8}$ or <u /> $\frac{-5}{2}$ reduced.

-5 ÷ 2 = -2 1/2 and that is the answer in simplest form
