Equation of a Straight Line
1.1 Solve y+2x-5 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y+2x-5 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000
y-intercept = 5/1 = 5.00000
Calculate the X-Intercept :
When y = 0 the value of x is 5/2 Our line therefore "cuts" the x axis at x= 2.50000
x-intercept = 5/2 = 2.50000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 1.000 - 5.000 = -4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -4.000/2.000 = -2.000
Geometric figure: Straight Line
Slope = -4.000/2.000 = -2.000
x-intercept = 5/2 = 2.50000
y-intercept = 5/1 = 5.00000
One of the original Seven Wonders of the World, the Great Pyramid of Cheops was built about 2580 BC. Its original height was 480 feet 11 inches, but owing to the loss of it's topmost stones, it is now shorter. Find the current height of the Great Pyramid using the information given in the illustration.
This value is approximate.
========================================================
Explanation:
The entire paragraph of text given to you is not needed. It's interesting that the height used to be 480 ft 11 in, but we don't use that anywhere in our calculations to get the current shorter height. Instead we rely solely on the diagram.
Refer to the diagrams I have posted below. Figure 1 is the same diagram more or less, but I've added the variables x and h.
x = horizontal distance from the center of the pyramid to the left most part of the pyramid.h = current height of the pyramidBoth h and x are in feet.
I've also added the point labels A through E.
I've split figure 1 into two pieces. Figure 2 focuses on triangle ADE and figure 3 focuses on triangle BDE.
---------------------
Let's put our attention on triangle ADE in figure 2.
Set up the tangent ratio shown below and solve for h.
[tex]\tan(\text{angle}) = \frac{\text{opposite}}{\text{adjacent}}\\\\\tan(\text{A}) = \frac{\text{DE}}{\text{AD}}\\\\\tan(40.3) = \frac{h}{x+200}\\\\h = (x+200)\tan(40.3)\\\\[/tex]
Now move onto triangle BDE in figure 3.
Set up the tangent ratio and apply substitution.
[tex]\tan(\text{angle}) = \frac{\text{opposite}}{\text{adjacent}}\\\\\tan(\text{B}) = \frac{\text{DE}}{\text{BD}}\\\\\tan(46.27) = \frac{h}{x+100}\\\\\tan(46.27) = \frac{(x+200)\tan(40.3)}{x+100}\\\\[/tex]
---------------------
Let's solve for x.
[tex]\tan(46.27) = \frac{(x+200)\tan(40.3)}{x+100}\\\\(x+100)\tan(46.27) = (x+200)\tan(40.3)\\\\x\tan(46.27)+100\tan(46.27) = x\tan(40.3)+200\tan(40.3)\\\\[/tex]
[tex]x\tan(46.27)-x\tan(40.3)=200\tan(40.3)-100\tan(46.27)\\\\x(\tan(46.27)-\tan(40.3))=200\tan(40.3)-100\tan(46.27)\\\\x=\frac{200\tan(40.3)-100\tan(46.27)}{\tan(46.27)-\tan(40.3)}\\\\x\approx 329.87238475414\\\\[/tex]
Use this to find h.
[tex]h = (x+200)\tan(40.3)\\\\h \approx (329.87238475414+200)\tan(40.3)\\\\h \approx 449.364461010933\\\\h\approx 449.364[/tex]
The height of the pyramid is currently 449.364 feet approximately.
---------------------
Lastly we'll convert to feet,inches format since the "480 ft 11 in" figure is in that format.
h = 449.364 ft
h = 449 ft + 0.364 ft
h = 449 ft + (0.364 ft)*(12 in/1 ft)
h = 449 ft + 4.368 in
h = 449 ft + 4 in
h = 449 feet, 4 inches

Which statement best describes a cause and effect structure of a speech?
o It discusses similarities and differences between two different topics,
O It shows the challenges of a topic and explains how the issue can be solved.
O It provides the audience with the order in which events happened.
o It presents the reasons something happened and describes the result.
Answer:
Fourth option
Step-by-step explanation:
Cause and effect all starts with a reason for a certain event, for example perhaps a group of children going into an abandoned house that is rumored to be "haunted", which caused an effect. So, in this case the children going into an abandoned house that is rumored to be haunted (cause) which then lead into a result, a ghost started to chase them around the house in till they could manage an escape. (effect) Although creating a very good story for us to read, cause and effect has real life examples. The answer is the fourth option or "it presents the reasons something happened and describes the result."

A certain journal likes to give new writers an opportunity. Therefore, there is a 40% chance that an author’s first article submitted will be published. But, that author’s second article submitted, and each article submitted after that, have only a 20% chance of being published. Past history of being published has no influence on whether a new article will be published.
(a) What is the probability that a new author will be published for the first time when he or she
submits a 4th article?
(b) What is the probability a new author will be published for the first time within his or her first 5
articles submitted?
Answer:
a
[tex]P(A_4) = 0.077[/tex]
b
[tex]P(A_5) =0.7542 [/tex]
Step-by-step explanation:
From the question we are told that
The chance that a new authors first article will be submitted is [tex]P(A) = 0.40[/tex]
The chance that a new authors next article will be submitted is [tex]P(N) = 0.20[/tex]
Generally the probability that a new author first article is not published is
[tex]P(A)' = 1 - 0.4 = 0.6[/tex]
Generally the probability that a new author next articles are not published is
[tex]P(N)' = 1 - 0.2 = 0.8[/tex]
Now from the question we are told to obtain the probability that a new author will be published for the first time when he or she submits a 4th article, which implies that the new authors first three articles where not published
So the probability is mathematically represented as
[tex]P(A_4) = P(A)' * P(N)' * P(N)' * P(N)[/tex]
=> [tex]P(A_4) = 0.6 * 0.8 * 0.8* 0.2[/tex]
=> [tex]P(A_4) = 0.077[/tex]
Generally the probability that a new author will be published for the first time within his or her first 5 articles submitted is equivalent to
1 - [The probability that a new author will not be published for the first time
within his or her first 5 articles submitted]
Now the probability that a new author will not be published for the first time within his or her first 5 articles submitted. is mathematically represented as
[tex]P(A_5)' = P(A)' * P(N)' * P(N)'*P(N)'* P(N)'[/tex]
=> [tex]P(A_5)' = 0.6 *0.8 * 0.8'*0.8* 0.8[/tex]
=> [tex]P(A_5)' = 0.24576 [/tex]
Generally the probability that a new author will be published for the first time within his or her first 5 articles submitted is mathematically represented as
[tex]P(A_5) = 1 - P(A_5)'[/tex]
=> [tex]P(A_5) = 1 -0.24576 [/tex]
=> [tex]P(A_5) =0.7542 [/tex]
