Reading the expression:We're given the sigma notation of a series.
[tex] \mathsf{ \sum _{k = 1} ^{5}(2k - 11) }[/tex]
The variable k is the "index of notation"
The expression can be read as the sum of (2k- 11) as k goes from 1 to 5.
"To generate the terms of a series given in sigma notation, successively replace the index of summation with consecutive integers from the first value to the last value of the index" ~internet

Generating the terms of the series:To generate the terms of the series given on sigma notation above, replace k by 1, 2, 3, 4, and 5 and add the terms, to get the answer to the given notation.
[tex]\mathsf{ \sum _{k = 1} ^{5}(2k - 11) } \\ = \mathsf{ \overline{2(1) - 11} + \overline{2(2) - 11} + \overline{2(3) - 11} } \\ \mathsf{ + \overline{2(4) - 11} + \overline{2(5) - 11}}[/tex]
[tex] = \mathsf{\overline{2 - 11} +\overline{4 - 11} + \overline{6 - 11} } \\ \mathsf{\overline{8 - 11} + \overline{10- 11}}[/tex]
[tex] = \mathsf{ - 9- 7 - 5 - 3 - 1}[/tex]

The statement below describes a situation in which opposite quantities combine to make zero:
A cup with a hole in it loses 2 ounces of water in the first minute and then loses 2 ounces of water in the second minute.
True
False
Answers
Answer: False
Step-by-step explanation:
A cup with a hole in it loses 2 ounces of water in the first minute. This mathematically means
Add -2 (loses ⇒ means getting less)
Then the cup loses 2 ounces of water in the second minute. This mathematically means
Add -2 (loses ⇒ means getting less)
In total, and means loses 4 ounces in two minutes.
Thus, the statement below does not describe a situation in which opposite quantities combine to make zero, so this statement is false

Answers
9514 1404 393
Answer:
6x -7 units
Step-by-step explanation:
Let c represent the length of the third side. The perimeter is the sum of the three side lengths.
P = a + b + c
(17x -5) = (3x +5) +(8x -3) +c
17x -5 = 11x +2 + c . . . . . . . . . . . . collect terms
6x -7 = c . . . . . . . . . . . . . . subtract 11x+2
The third side is 6x -7 units.

Read the summary of the section of "The Beginnings of the Maasai,” where the volcanic eruption and its results are described.
As a result of a volcanic eruption, the sky god Enkai and the cattle were thrown into the sky. Enkai wanted to save his cattle. He grew a tree that bridged the sky and the earth. The cattle walked down the tree to Neiterkob. Neiterkob and the Maasai tribe took over caring for the cattle.

Sorry if it is wrong :(
The summary needs to be revised because The summary lacks transitions that connect ideas.
What is a summary?
A summary is a brief statement or account of the main points of something. The summary is essentially a short version of a longer text. The size of a summary can vary based on the type of writing, but most often it is no longer than a page.
They are used to give an overview of what happens in the writing and review the main themes. This lesson will continue to explore what summary writing is, types of summaries, and examples of summaries.
Keeping the summary concise will give the reader the information they need the most, without any unnecessary information.
What is a volcanic eruption?A volcanic eruption is when lava and gas are released from a volcano—sometimes explosively. The most dangerous type of eruption is called a 'glowing avalanche' which occurs when freshly erupted magma flows down the sides of a volcano.
Volcanic eruption can come from side branches or from the top of the volcano. Some volcanic eruption are terrible explosions that throw out huge amounts of rock and volcanic ash and can be disastrous for the people and animals that are living nearby to it .
Volcanic eruption are often named after famous volcanoes where that type of eruption has been seen. Some volcanoes may show only one type of eruption during a period of activity, while others may show a range of types in a series.

A flash disk has the capacity of storing 1 megabyte of data. How many kilobytes of data can be stored in the same flash disk
Answers
For this sort of problem, you need to be familiar with prefixes.
So:
megabyte = [tex]1 *10^6[/tex] bytes
kilobyte = [tex]1*10^3[/tex] bytes
and a regular byte would just be [tex]1[/tex]
Now, you will need to do a conversion:
[tex]1megabyte*\frac{1*10^6bytes}{1megabyte}*\frac{1*10^{-3}kilobyte}{1byte}[/tex]
I'm going to explain this just in case, but we convert megabytes to regular bytes in the first half by using the information I gave you above. (In one megabyte, there are [tex]1*10^6[/tex] bytes!)
In the second fraction thought, remember one kilobyte is [tex]1*10^3[/tex] bytes. However, you usually only see one of each thing on the bottom of fractions, so you need to add a negative sign to the 3. (technically you could just do [tex]\frac{1kilobyte}{1*10^3bytes}[/tex], but I think it is more correct to do write it out how I did).
*** They do equal the same thing though! Do whichever way is easier for you!
Now, your answer should be:
[tex]10^3[/tex] kilobytes (1000 kilobytes)

How to put y=14x-62 in standard form, pls explain.
Answers
Answer:
14x - y = 62
Step-by-step explanation:
Hi there!
We are given the equation y=14x-62 and we want to put it into standard form.
Standard form is ax + by = c, where a, b, and c are free integer coefficients, but a and b cannot be equal to zero, and a cannot be negative
The equation is currently in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
Since standard form has the term with x in it on the left side, we can move 14x to the left side (subtract 14x from both sides)
y = 14x-62
-14x -14x
_________________
-14x + y = -62
Remember that a (coefficient of x) cannot be negative. So multiply everything by -1 to change the sign of all the terms
-1(-14x + y) = -1(-62)
14x - y = 62
Hope this helps!

Answers
Answer:
See below
Step-by-step explanation:
a + 54° = 180° [Angles on a straight line]
a = 180 - 54
a = 126°
a + b = 180 [Angles on a straight line add up to 180 degrees]
126 + b = 180
b = 180 - 126
b = 54°
c° = a° [Vertically opposite angles are equal]
c° = 126°

Step-by-step explanation:
Because [tex]\cos{x}[/tex] and [tex]\sin{x}[/tex] are defined for all [tex]x[/tex](i.e. their domain is [tex](-\infty, \infty)[/tex]), so they can never be undefined. However, [tex]\tan{90}=\sin{90}/\cos{90}=\sin{90}/0[/tex], which is undefined, because you can't divide by [tex]0[/tex]. So, the answer is [tex]\boxed{\tan{90^{\circ}}}[/tex]

Write an equation of the line that passes through the point (4, –5) with slope 2.
A. y−4=−2(x+5)
B. y+5=2(x−4)
C. y−4=2(x+5)
D. y+5=−2(x−4)
Answers
Answer:
The correct choice is option B. y + 5 = 2(x−4)
Step-by-step explanation:
slope = 2
y = mx + b
-5 = 2(4) + b
-5 = 8 + b
-8 -8
------------------
-13 = b
y = 2x - 13, in other words --> y + 5 = 2(x−4)
So, y + 5 = 2(x − 4) is the equation of the line that passes through (4, -5).
