Step-by-step explanation:

sin(3π/4 - β) = sin(3π/4)cosβ - cos(3π/4)sinπ =

[tex]\sin(\frac{3\pi}{4}-\beta)=\sin(\frac{3\pi}{4})\cos\beta-\cos\frac{3\pi}{4}\sin\beta\\=\frac{1}{\sqrt{2}}\cos\beta-(-\frac{1}{\sqrt{2}})\sin\beta\\\\=\frac{1}{\sqrt{2}}(\cos\beta +\sin\beta)\\\\\sin^2(\frac{3\pi}{4}-\beta)=\frac{1}{2}\cos\beta +\sin\beta)^2=\frac{1}{2}(\cos^2\beta +\sin^2\beta+2\sin\beta\cos\beta\\=\frac{1}{2}(1+\sin2\beta)=\frac{1}{2}(1-\frac{1}{5}) = \frac{2}{5}\\[/tex]

Use [tex]\cot^2x=\csc^2x-1=\frac{1}{\sin^2x}-1[/tex]

so

[tex]\cot^2(\frac{3\pi}{4}-\beta)=\frac{1}{\sin^2(\frac{3\pi}{4}-\beta)}-1 = \frac{1}{\frac{2}{5}}-1=\frac{5}{2}-1=\frac{3}{2}[/tex]

Answer:

2 vertical and -11 horizontal

Step-by-step explanation:

Answer:

y = -8

Step-by-step explanation:

y = 3

is a "flat" horizontal line, which means every point on that line has the same y value no matter what x value we would consider.

any line parallel to that is then also a horizontal line with a constant y value. which y value ? well, the y coordinate of the given point tells us : (-2, -8)

so, the line equation is

y = -8

Answer:

C,  y=-8    

Step-by-step explanation:

Which equation represents the line that is parallel to y= 3 and passes through (-2,-8)?

y=3 means the y value is always 3, so the line is horizontal and parallel to the y axis.

A, x= -2    this is a vertical line

B. x= 3      this is a vertical line

C,  y=-8     this is a horizontal line, where y is always -8 so it is parallel and will pass through -2

D, y= 3x-2 this line will be at an angle

Draw two lines of 7 cm at an angle of 85° and 120°. Then join the terminal of the lines. The quadrilateral is formed. The length of the fourth side of the quadrilateral is 7.5 cm.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees.

Three of its four sides measure 7 centimeters each.

The angles between these sides have measures of 85° and 120°.

First, draw two lines of 7 cm at an angle of 85°. And from another end of the line draw a 7 cm line at an angle of 120°.

Then join the terminal of the lines. The quadrilateral is formed.

The length of the fourth side of the quadrilateral is 7.5 cm.

Answer:

y= 8000x + 2000

Step-by-step explanation:

to find the formula we can use the points given in the question:

the slope:

to get the slope we can take the 2 points, (0,2000) and (2,18000) where x values are time and y values are bacteria

now using slope-intercept form we can get [tex]\frac{18000-2000}{2-0}[/tex] which gives a slope of 8000 meaning for each hour there are 8000 new bacteria

intercept:

since we start with 2000 bacteria we know this is the y intercept so when x is 0

formula:

y=8000x + 2000

Using a system of equations, it is found that the height of the TV is of 20 inches.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

The height of the screen of the tv is one half the width plus 5 inches, hence:

h = 0.5w + 5.

Since the width is of 30 inches:

h = 0.5 x 30 + 5 = 15 + 5 = 20.

The height of the TV is of 20 inches.

[tex]\dfrac{GK}{VR}=\dfrac{KN}{RP}\\\\\\\dfrac{14.7}{6.3}=\dfrac{x+1}{4x-3}\\\\\dfrac{0.7*10}0.3*10}=\dfrac{x+1}{4x-3}\\\\\dfrac{7}{3}=\dfrac{x+1}{4x-3}[/tex]

Cross multiply

7*(4x-3)=3*(x+1)

28x - 21 = 3x + 3

28x - 3x - 21 = 3

The matrix shown represents its elements in rows and columns

Using the assumed matrix, the operation performed on the initial matrix to determine the new resultant matrix is R3 -> 2R2 + R3.

The question is incomplete, as the matrix is not shown.

So, I will give a general explanation.

Assume that the matrix is given as:

[tex]\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&2&4&5\end{array}\right][/tex]

Multiply the elements on the second row (Row 2) by 2.

So, we have:

2R2 = 0 -2 6 2

Add these elements to the third row (Row 3).

So, we  have:

2R2 + R3 = 3 0 10 7

Replace the row 3 by the above elements.

i.e.

R3 -> 2R2 + R3.

So, we have:

[tex]\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&0&10&7\end{array}\right][/tex]

Hence, the operation performed on the initial matrix to determine the new resultant matrix is R3 -> 2R2 + R3.

Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques.

Answer: I don’t know if you want the area or just y but anyways, y= 9

Step-by-step explanation:

The question requires a scale factor (since both triangles have similar sides (an equal ratio is a good way to think about it) the 10cm side of the large triangle is proportionate to the same side of the smaller triangle.

In other words to get that scale factor (how much one shape is bigger than the other) we need to divide the 10 by 4 (you need to use the same side you can’t do 10/6 because they are completely different sides) 10/4 = 2.5

Now we know the larger triangle is 2.5 times bigger than the smaller triangle. This means the smaller triangle is 2.5 times smaller than the big triangle. So to find the base of the larger triangle we use a similar method we used to find the scale factor (but not divide multiply because when you want to find the bigger you multiply when you want to find scale factor/ smaller you divide) so 6* 2.5= 15 and since y is not the entire base only a part of it, we can do 15(which is the entire length of the big triangle base) - 6 = 9

Therefore y=9
