Answer:

Option D.

Step-by-step explanation:

The given relation is

{(4,5), (-1, 5), (1, 9), (-5, 3), _?}

We need to find the ordered pair that could replace the missing value and create a function.

A relation is called a function if there exist a unique output for each input.

The input values of the given function are 4, -1, 1 and -5.  

For point (1,-3), the given relation has two outputs -3 and 9.

For point (-5,4), the given relation has two outputs 4 and 3.

For point (4,3), the given relation has two outputs 3 and 5.

For point (5,-1), the given relation has exactly one output, i.e., -1.

Therefore, the correct option is D.

In 2015 Michael purchased a stock for $45.80 a share. During the year he received $1.71 per share in cash dividends. At the end
timama [110]
Michael's initial investment is $45.80, the cost of the share. 
Michael Receives $1.71 in dividends.
He receives $47.50 for the stock when he sells it.
His profit on the sale of the stock is $47.50 - 45.80 = $1.70.
His total return on the stock is his total earnings, the dividends plus his profits on the sale of the stock, divided on what he paid initially, $45.80:
(1.71 + 1.70) ÷ 45.80 = .0744 = 7.45%
7.45% return on investment in less than a year, not bad!
Closest answer is 7.7%, not sure why it isn't exactly 7.45 or 7.5%. 

Answer is B) 7.7%

What is the value of x?
QveST [7]

Answer:

72°

Explanation:

Given that line J and line K are parallel, we can safely assume that line m is the transversal for the following question. We can also remove line l so that we can focus on line m instead.

Using the rule of <u>Alternate Exterior Angle</u> theorem, x would equal to 72°.

I need help with this question please.​
MakcuM [25]

Answer:

30 degrees.

Step-by-step explanation:

Rotational symmetry is defined as a figure having the same appearance when rotated by a certain angle.

The wheel has 12 "handles." We can use these as reference points when rotating the image.

We also know that we can rotate by a total of 360 degrees. We can say that:

360/12 = 30 degrees.

Each time you rotate the wheel by 30 degrees, the image will end up on another handle (looks the same). This shows rotational symmetry.

I hope this helps!
