Determine the domain and range of this set of ordered pairs.

Mathematics
1 answer:
Darya [45]3 years ago
3 0

Answer:

Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}

Step-by-step explanation:

{(2,4), (8,-3), (-5,-1), (4,6), (6,7), (9,0)}

The domain is the input and the range is the output

domain is { 2,8,-5,4,6,9} and the range is {4,-3,-1,6,7,0}

We put the numbers in order from smallest to largest

Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}

Which ordered pair word form a proportional relationship with the point graph below
tatuchka [14]

Answer:

D. (90, 60)

Step-by-step explanation:

A proportional relationship is a relationship in which the ratios of two variables are equivalent.

If we take two points on the graph such as (45, 30) and (30, 20), we can see that they can both be simplified to the ratio 3:2. Using this we can find the correct answer. From looking at all the points we can see that only (90,60) would also form a ratio of 3:2, thus d would be the correct answer.

In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angl
AlladinOne [14]

60° + 70° + y° = 180°

130° + y° = 180° ~Subtract 130° from both sides

y° =50°

y=x because they are both vertical angles

x° = 50°

  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u>Step 1: Set Up Equation</u>

53° + 97° + x° = 180°

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine Like Terms:                     x° + 150° = 180°
  2. Isolate <em>x</em>:                                          x = 30°

ryzh [129]

Answer:

144π or 452.4

Step-by-step explanation:

Volume of a Sphere Formula: V = 4/3πr³

Step 1: Plug in 6 for <em>r</em>

V = 4/3π(6)³

V = 288π

Step 2: Divide by 2

V = 288π/2

V = 144π
