Mathematics

lawyer [7]3 years ago

Answer:

The slope of the line is -3

Step-by-step explanation:

Slope formula:

m = y₂ - y₁ / x₂ - x₁

Get any two points:

(-2, 4) and (-1, 1)

Solve:

m = 1 - 4 / -1 - (-2)

m = -3 / -1 + 2

m = -3 / 1

m = -3

Check for the third point just in case.

Two points:

(-1, 1) and (1 , -5)

Solve:

-3 = -5 - 1 / 1 - (-1)

-3 = -6 / 1 + 1

-3 = -6 / 2

-3 = -3

So -3 is the legit slope of the three collinear points.

10. A triangle has sides with lengths 3,5, 7. Is this an acute, obtuse, or right<br> triangle?
satela [25.4K]

Answer:

OBTUSE

Step-by-step explanation:

You would first have to figure this put via Pythagorean theroem. Basically do this (attachment)***C IS THE LARGEST NUMBER*** and know that c^2 < a^2 + b^2 (less than) = ACUTE, c^2 > a^2 + b^2 (greater than) = OBTUSE, and c^2 = a^2 + b^2 is RIGHT. If it is Right with all different numbers, it is SCALENE.

Answer:

A ≈ 9.0 ft²

Step-by-step explanation:

70° = 7π/18 radians

Area of the arc section

A = ½(7π/18)8² = 12⁴/₉π ft² = 39.09537 ft²

As the triangle is isosceles, the other two angles are (180 - 70) / 2 = 55°

law of sines 8 / sin55 = L / sin 70  L = 9.17722

so the triangle height  = √(8² - (9.17722/2)²) = 6.55321

Area of triangle ½(6.55321)(9.17722) = 30.07016

Area = 39.09537 - 30.07016 = 9.025211 ≈ 9.0 ft²

Does anyone get this??
kirill115 [55]

Answer:

The distance from the feet to the wall is 9 ft

Step-by-step explanation:

Using trig,

We must use cosine to find the missing side.

The equation is cos 60 = \frac{adjacent}{18}

The cosine of 60 is 1/2

So, we multiply 1/2 by 18

to get 9

Hope this helps!
