Find the slope of a line perpendicular to Y= -x -1

Mathematics
1 answer:
ad-work [718]3 years ago

<h2>Greetings!</h2>

Answer:

The slope is 1.

Step-by-step explanation:

First, we must find the slope of the current equation.

This is the number in front of the x.

Seeing as this is -x, or -1x, the slope of this line is -1

When finding the slope of a line perpendicular, you need to find the \frac{-1}{slope}

So, in this case it is:

\frac{-1}{-1}

The minuses cancel out, leaving with 1 over 1 or 1/

So the slope of the line perpendicular is 1!

a ladder leans against the sufe of a house. the angle of elevation of the ladder is 70 degrees when the bottom of the ladder is
nekit [7.7K]

Answer:

≈ 35.1 ft

Step-by-step explanation:

The model is a right triangle with ladder being the hypotenuse and the angle between the ground and the ladder is 70°

Using the cosine ratio, with l being the length of the ladder.

cos70° = \frac{adjacent}{hypotenuse} = \frac{12}{l} ( multiply both sides by l )

l × cos70° = 12 ( divide both sides by cos70° )

l = \frac{12}{cos70} ≈ 35.1 ( to the nearest tenth )

The ladder is approx 35.1 ft long

Plz help.............. radius is 10 inch​
yaroslaw [1]

Answer:

314 in²

Step-by-step explanation:

The formula for the area of a circle is pi*r² or pi (3.14...)* radius²(squared).

If you plug in the radius given into the equation, you get 3.14*10²  you can then solve this using systems of equations.

3.14*10²

10² = 10*10

3.14*(10*10)

10*10= 100

3.14*100

3.14*100= 314
