Answer:

D) 2x² + x - 10

Step-by-step explanation:

First, distribute the negative sign to all terms within the second parenthesis:

- (4x - x² + 6) = -4x + x² - 6

Next, combine like terms:

5x + x² - 4 - 4x + x² - 6

(x² + x²) + (5x - 4x) + (-4 - 6)

2x² + x - 10

2x² + x - 10 , or D) is your answer.

Eight identical slips of paper, each containing one number from one to eight, inclusive, are mixed up inside a bag. Subset A of

DochEvi [55]

Answer: The correct option is (C) A = {1, 2, 3, 4, 5, 7, 8}.

Step-by-step explanation: Given that eight identical slips of paper, each containing one number from one to eight, inclusive, are mixed up inside a bag.

The sample space, S will be

S = {1, 2, 3, 4, 5, 6, 7, 8}.

Subset A of the sample space represents the complement of the event in which the number 6 is drawn from the bag.

Let, 'B' represents the event in which the number 6 is drawn from the bag.

So, B = {6}.

Since 'A' is the complement of 'B', so the set 'A' will contain those element of the sample space 'S' that are not in the set 'B'.

Therefore,

A = B' = {1, 2, 3, 4, 5, 7, 8}

⇒ A = {1, 2, 3, 4, 5, 7, 8}.

Thus, (C) is the correct option.

A surveyor measures the angle of elevation of the top of a mountain from a point at

Sauron [17]

The height of the mountain from a point a sea level is approximately 1496.650 meters.

<h3>What is the height of mountain from sea level?</h3>

First, we construct the <em>geometric</em> diagram of the situation and find all needed angles and sides to determine the height of the mountain. First, we determine the missing side x by the law of sines:

Law of sines

1000 m/sin 3° = x/sin 14.261°

x ≈ 4706.886 m

Now we determine the height of the mountain by <em>trigonometric</em> functions:

h = 100 m + (4706.886 m) · sin 17.261°

h ≈ 1496.650 m

The height of the mountain from a point a sea level is approximately 1496.650 meters.

Solve for the equation for X. 1.07=x-780/28

sdas [7]

Answer:

x = 28 649/700

Step-by-step explanation:

Add 780/28.

1.07 +780/28 = x

x = 28 649/700 = 28.92_714285(repeating)

_____

If one were concerned with significant digits, one could argue that the value should be rounded to 28.93, the precision of 1.07.
