Considering the given linear function, it is found that table B represents the situation.

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

In this problem, the function is given by:

y = 2x + 30.

Hence, the y-intercept is of b = 30, that is, when x = 0, y = 30, and the slope of m = 2 means that when x increases by 1, y increases by 2, hence table B is the answer for this question.

Answer:

Step-by-step explanation:

2cos²θ - 1 - cosθ = 0

(2cosθ + 1)(cosθ - 1) = 0

cosθ = -1/2, θ = 2π/3, 4π/3

cosθ = 1, θ = 0

so answer is 3rd choice

Answer:

(6, 11)(8, 15)(9, 17)(10, 19)

Step-by-step explanation:

ohhhh

sooo

y = 2(6) - 1

y = 12 - 1

y = 11

(6, 11)

y = 2(8) - 1

y = 16 - 1

y = 15

(8, 15)

y = 2(9) - 1

y = 18 - 1

y = 17

(9, 17)

y = 2(10) - 1

y = 20 - 1

y = 19

(10, 19)

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."

Hope this helps.

========================================================

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.

Both 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

Arithmetic mean is also called average it is calculated by summing the values then dividing by the number of sets

(22,000 + 23,100 + 26,300 + 30,100 + 39,000 + 148,500) / (15 + 12 + 16 + 4 + 4 + 1)

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

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]

Answer:

2/30 or 5/30

Step-by-step explanation:

The simplest form of the expression is 1/6.

We have,

The concept used to solve the division problem 4/5 divided by 6 is the idea of dividing a fraction by a whole number.

To divide a fraction by a whole number, we can interpret it as finding a fraction of a fraction.

In this case, we want to find 4/5 divided by 6, which can be understood as dividing the fraction 4/5 into 6 equal parts.

To use a model to divide 4/5 by 6, we can represent 4/5 as a fraction bar and divide it into 6 equal parts.

If we divide the fraction 4/5 into 6 equal parts, each part would represent 1/6 of the original fraction.

Therefore,

The simplest form of the expression is 1/6.

figure 1 is 130 degrees because a whole line is 180 degrees subtract the 50 boom.

figure 2 is a bit more difficult all together it is 360 y is 30 degrees due to vertical angles and x and z are 150 degrees because 360-60=300 divided by 2 equals 150

figure 3 x is 135 due to vertical angles which makes w and y are 45 because 360-270 equals 90 divide by 2 equals 45

figure 4 is 106 because you add 172 and 82 and then subtract that by 360 there you go. hope this helps you out

Step-by-step explanation:

Like I said, all the angles of a triangle ALWAYS add up to 180 degrees (which is a straight angle). It might seem like they don't give angle A for us, but we can see that angle A is a right angle, which is 90 degrees. So, we can add 90 and 34 degrees, and then subtract that from 180.

90 + 34 = 124

180 - 124 = 56
