DochEvi [55]

Answer:

h= 4.6, c=7.1

Step-by-step explanation:

First you need to know in a 30 60 90 triangle the sides ratios are x, 2x and x√3, and for 45 90 45 it is x, x and x√2

so <em>h</em> is 8/√3 and you rationalize the bottom so it becomes 8√3/3. when you solve this and round to nearest hundred it becomes 4.6. for the second one, it is 5√2 and when you solve this and round, it becomes 7.1

vodomira [7]

Answer:

3.14

Step-by-step explanation:

First find the circumference of the circle:

2\pi r = Circumference.

2 * \pi * 6 = 12\pi

Find the ratio of the angle in relation to the entire circle:

30^o is what we have. So:

\frac{30^o}{360^o} = \frac{1}{12}

Use the ratio and multiply the circumference to find the length:

12\pi * \frac{1}{12} = \pi

Round answer to the hundredth:

\pi = 3.14

Answer:

{-8, -7, 0, 6, 9}

Step-by-step explanation:

1. The range of a relation is the set of its possible output values, also known as the y-values of a function.

2. Let's find the y-coordinate of each point.

  • 9, 6, 0, -7, -8

3. Now, let's order them (from least to greatest) to get the range.

  • -8, -7, 0, 6, 9
  • {-8, -7, 0, 6, 9}

Therefore, the range of this relation is {-8, -7, 0, 6, 9}.
