Find the slope of the line through the following points. (-1, -4) and (-3,4)
A. 1/4
B. -1/4
C. 4
D. -4
Answers
Answer:
The answer is C, the slope is 4.
Step-by-step explanation:
Finding slope using two given points is easy. You need to do (y2-y1/x2-x1)
(-1,-4) the -1 is x1 and the -4 is y1. (-3,4) the -3 is x2 and the 4 is y2.
You plug them into the formula giving you
(4-(-4)/ -3-(-1)= 8/-2= 4
Rachelhasalreadywritten10pages,andsheexpectstowrite1pageforeveryadditionalhourspentwriting.HowmanyhourswillRachelhavetospendwritingthisweekinordertohavewrittenatotalof27pages?
Answers
Answer:
17 hours
Step-by-step explanation:
Rachel has already written 10pages, and she expects to write 1page for every additional hour spent writing. How many hours will Rachel have to spend writing this week in order to have written a total of 27pages?
The illustration can be modelled using the equation
y = 10 + 1(x)
y = 10 + x
Where,
y = total number of pages
x = number of hours
10 = pages already written
If y = 27 pages, find x
y = 10 + x
27 = 10 + x
27 - 10 = x
17 = x
x = 17 hours
Rachel have to spend 17 hours writing this week in order to have written a total of 27pages

Refer to the various selling prices of various homes in a community that follow the normal distribution with mu (population mean) = $276,000 and sigma (standard deviation – measure of dispersion) = $32,000. Calculate the probability that the next house in the community will sell for between $276,000 and $325,000.
Answers
Answer:
0.43715
Step-by-step explanation:
We solve using z score calculator
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = $276,000
σ is the population standard deviation = 32,000
For x = $276,000
z = 276,000 - 276,000/32000
z = 0
Probability value from Z-Table:
P(x = 276000) = 0.5
For x = $325,000
z = 325,000 - 276,000/32000
z = 1.53125
Probability value from Z-Table:
P(x = 325000) = 0.93715
The probability that the next house in the community will sell for between $276,000 and $325,000 is
P(x = 325000) - P(x = 276000)
= 0.93715 - 0.5
= 0.43715

Find the EXACT value of sec (-120 degrees)
Answers
Well sec(-120) = 1/cos(-120).
We know that cos(-120) = -1/2.
So, 1/(-1/2) = -2.
This means that sec(-120) = -2.
the graph of a linear equation in two variables is _____?
Answers
Answer:
"a straight line"
Step-by-step explanation:
recall that a linear equation may be expressed as
y = mx + b, where x and y are the variables (i.e 2 variables)
we also know that if we graph the linear equation y = mx+b, we will get a straight line.
Hence a possible answer for the blank could be:
"a straight line"
A circus audience sits in rows around the performing ring. There are 9 seats in each row. How many rows will need to be set up if 513 people are expected to attend the show?
Answers
Answer:
57 rows
Step-by-step explanation:
Since each row will have a total of 9 seats, then we would simply need to divide the total number of individuals that will attend the show by 9 in order to calculate the number of rows that need to be set up around the performing ring.
513 / 9 = 57 rows
Therefore, we can see that we would need a total of 57 rows of 9 chairs each in order for there to be enough chairs to seat 513 people.
the sum of the interior angles in a pentagon
Answers
Answer:
540°
Step-by-step explanation:
When you have a polygon (shape with 3+ sides), you can split the shape into the lowest number of triangles and use that to calculate the interior angles of the shape. Thus works because triangles have angles that always add up to 180°
A Pentagon can be split into 3 triangles minimum, which means you have 180 + 180 + 180. Or...
180 x 3 = 540

Given \sec A=\frac{14}{\sqrt{171}}secA= 171 14 and that angle AA is in Quadrant I, find the exact value of \csc AcscA in simplest radical form using a rational denominator.
Answers
Answer:
Step-by-step explanation:
[tex]sec A=\frac{14}{\sqrt{171} } \\cos ~A=\frac{\sqrt{171} }{14} \\sin ~A=\sqrt{1-cos^2A} =\sqrt{1-\frac{171}{196} } =\sqrt{\frac{196-171}{196} } =\sqrt{\frac{25}{96} } =\pm\frac{5}{14} \\csc A=\pm \frac{14}{5}[/tex]
as A is in quadrant 1
[tex]so~csc~A=\frac{14}{5}[/tex]
in quadrant 1 both sin A and csc A are positive.

Answer:
X = 12
Step-by-step explanation:
Since each angle is equivalent to each other, you can write the equation:
(9x-3) = (7x+21)
Then Simplify.
Subtract both sides by 7x
2x-3=21
Add 3 To Both Sides
2x=24
Divide by 2
X = 12
Answer:
9x-3=7x+21
9x=7x+24
2x=24
x=12
Step-by-step explanation:
(9x-3) and (7x+21) are corresponding angles that means that they are congruent. So they equal each other.
