The angular velocity is the linear speed divided by the radius.
  ω = d/(t*r) = (14.13 ft)/((3 s)*(6 ft))
  ω = 0.785 radians/second
There are 180/π degrees per radian, so the angular velocity can also be written as ...
  ω = 45 degrees/second

(2x-1)(x+5)(3x-2) expanded and simplified
STatiana [176]
To simplify, we can use the FOIL method. That stands for first, outer, inner, last. What we do is take two factors at a time and multiply the first terms by each other, the outer terms together, etc.

Let's start with (2x-1) and (x+5)

First: 2x * x = 2x^2
Outer: 2x * 5 = 10x
Inner: -1 * x = -x
Last: -1 * 5 = -5

2x^2 + 9x - 5

Now FOIL this result with (3x - 2)

6x^3 - 4x^2 + 27x^2 - 18x - 15x + 10

Simplify:

6x^3 - 23x^2 - 33x + 10

Find the missing length of the triangle.
jek_recluse [69]

Answer:

a = 13.8

(missing length of triangle = 13.8 meters)

Step-by-step explanation:

The side lengths of a triangle can be related using the Pythagorean Theorem;

a² + b² = c²

where

a = one side length

b = other side length

c = hypotenuse (long side --across from 90° angle)

So, by plugging our values into the Pythagorean Theorem, we can solve for a:

a = unknown

b = 18.4

c = 23

a² + b² = c²

a² + 18.4² = 23²

a² + 338.56 = 539

    - 338.56   - 338.56       {subtract 338.56 from both sides to isolate a}

a² = 190.44

√a² = √190.44

a = 13.8

so, the missing length of the triangle is 13.8 m

hope this helps!!
