Find the value of x in the
following parallelogram:
2x - 1
11
7
x = [?]

Answers

Answer 1

Answer:

[tex]x = 4[/tex]

Step-by-step explanation:

See attachment for complete question

From the attachment, the parallelogram has two diagonals. And the diagonals of a parallelogram bisect one another.

Because 2x - 1 and 7 are opposite sides of a diagonal; We can say that:

[tex]2x - 1= 7[/tex]

Add 1 to both sides

[tex]2x - 1 + 1 = 7 + 1[/tex]

[tex]2x = 8[/tex]

Divide through by 2

[tex]x = 4[/tex]

Step-by-step explanation:

Step 1: Define

[tex]f(x) = \frac{1}{\sqrt{800-2x} }[/tex]

Step 2: Identify Variables

Using U-Substitution, we set variables in order to integrate.

[tex]u = 800-2x\\du = -2dx[/tex]

Step 3: Integrate

Define:                                                                                                            [tex]\int {f(x)} \, dx[/tex]Substitute:                                                                                         [tex]\int {\frac{1}{\sqrt{800-2x} } } \, dx[/tex][Integral] Int Property:                                                                                     [tex]-\frac{1}{2} \int {\frac{-2}{\sqrt{800-2x} } } \, dx[/tex][Integral] U-Sub:                                                                                           [tex]-\frac{1}{2} \int {\frac{1}{\sqrt{u} } } \, du[/tex][Integral] Rewrite:                                                                                          [tex]-\frac{1}{2} \int {u^{-\frac{1}{2} }} \, du[/tex][Integral - Evaluate] Reverse Power Rule:                                                 [tex]-\frac{1}{2}(2\sqrt{u}) + C[/tex]Simplify:                                                                                                         [tex]-\sqrt{u} + C[/tex]Back-Substitute:                                                                                            [tex]-\sqrt{800-2x} + C[/tex]Factor:                                                                                                           [tex]-\sqrt{-2(x - 400)} + C[/tex]

Step 4: Identify Domain

We know from a real number line that we cannot have imaginary numbers. Therefore, we cannot have any negatives under the square root.

Our domain for our integrated function would then have to be (-∞, 400]. Anything past 400 would give us an imaginary number.

An oil drilling company drills the same distance each day for 5 days. They started at an elevation of 121.175 feet and ended at an elevation of -246.875 feet. Which equation can be used to find x, the distance they drilled each day?

Answers

Answer:

[tex]x=\dfrac{|-246.875-121.175|}{5}[/tex]

Step-by-step explanation:

Given that:

Same distance is drilled by the oil drilling company for 5 days.

Initial elevation = 121.175 feet

Final elevation = -246.875 feet

To find:

The equation to find the value of [tex]x[/tex] i.e. the distance drilled each day?

Solution:

To find the distance drilled each day, we need to divide the total distance drilled with the number of days taken to drill the total distance.

Total distance drilled can be found by subtracting the initial elevation from the final elevation and taking modulus because distance can not be negative.

Total distance drilled = | Final elevation - Initial elevation |

Total distance drilled = | -246.875 - 121.175 |

Therefore, we can write the expression as:

[tex]x=\dfrac{|-246.875-121.175|}{5}[/tex]

[tex]\Rightarrow x=\dfrac{|-368.05 |}{5} =73.61\ ft/day[/tex]

Since you're only given the one vector, I assume you're supposed to find the magnitude of v, or ||v||, using the dot product.

We have

v • v = (-2, -1) • (-2, -1) = (-2)² + (-1)² = 5

The length of a rectangle is twice its width, while the
perimeter of the rectangle is 36 units. . Which system of
equations can be used to find the length ( and the width w
of the rectangle?

Answers

Answer: Length = 12 units

Width = 6 units

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Since the length of a rectangle is twice its width, thus means that the length will be: = 2x

Perimeter of a rectangle = 2(l + w)

where,

L = length

W = width

Therefore,

Perimeter = 2(l + b)

36 = 2(2x + x)

36 = 2(3x)

36 = 6x

x = 36/6

x = 6

Width = 6 units

Length = 2 × Width = 2 × 6 = 12 units

Shane and Gemma share 35 sweets in the ratio 1:4
1
Gemma eats 10 of her sweets and then gives Shane 2 of the sweets she has left.
(c) How many sweets does Shane have now?​

Answers

Answer:

Shane has 9 sweats now.

Step-by-step explanation:

Given that Shane and Gemma share 35 sweets in the ratio 1:4.

Let the share of Shane be = 'x'

Let the share of Gemma be = '4x'

The combined share of Shane and Gemma = x + 4x = 5x

Total sweets they share = 35

so the equation becomes

5x = 35

x = 7

Thus,

Share of Shane = x = 7

Share of Gemma = 4x = 4(7) = 28

Gemma eats 10 sweets, so she has left with 28-10 = 18 sweets

Gemma gave 2 of the sweets she has left.

As Shane has already 7 sweats, so adding 2 in 7 sweats would make it 9 sweats.

Therefore, Shane has 9 sweats now.

Is the relation a function? If it is a function, state the domain and range. If not, circle or
highlight the part that causes it to not be a function.

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Writing this relation in set notation using curly braces:

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

The relation clearly indicates that each input is related to exactly one output. In other words, there is no repetition of 'x' values.

Hence, this relation is a function.

We know that the domain is the set of all x values.

Thus, the domain is: {1, 2, 3, 4, 5}

We know that the domain is the set of all y values.

Thus, the range is: {-1, 0, 3, 5, 6}

A bag contains five ping-pong balls numbered 1 to 5. Two balls are removed to form a two digit number. The smallest possible number is 12 and the largest is 54. What is the probability that the number formed is prime? (hint: Write out the entire sample space)

Answers

Answer:

[tex]\frac{11}{42}[/tex] or 26.19%

Step-by-step explanation:

If the range of possible numbers is between 12 and 54 then that means that there are 42 (54 - 12) possible numbers that can be made. In this range, there are 11 prime numbers which are the following...

13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53

Therefore, the probability that the number formed is a prime would be [tex]\frac{11}{42}[/tex] which if we divide and multiply the decimal by 100 we get the probability in percentage form.

[tex]\frac{11}{42}[/tex] = 0.2619

0.2619 * 100 = 26.19%

Finally, we can see that the probability of this happening is 26.19%
