solve trigonometric function
cot0/tan0
Answer:
[tex]\dfrac{1}{\tan^2(\theta)}}=\cot^2(\theta)[/tex]
Step-by-step explanation:
[tex]\cot(\theta)=\dfrac{1}{\tan(\theta)}[/tex]
[tex]\implies \dfrac{\cot(\theta)}{\tan(\theta)}=\dfrac{1}{\tan(\theta)}\div{\tan(\theta)}}=\dfrac{1}{\tan(\theta)} \times \dfrac{1}{\tan(\theta)} =\dfrac{1}{\tan^2(\theta)}}=\cot^2(\theta)[/tex]
[tex]\\ \rm\Rrightarrow cotA\div tanA[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{cosA}{sinA}\div \dfrac{sinA}{cosA}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{cosA}{sinA}\times \dfrac{cosA}{sinA}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{cos^2A}{sin^2A}[/tex]
[tex]\\ \rm\Rrightarrow cot^2A[/tex]

Answer:
Step-by-step explanation:
As we can see that Line WL is a straight line that the angles that make up it like Angle HJW and Angle GJH and Angle LJG all equal to 180 degrees
Angle HJW = 18 degrees
ANGLE GLH = 90 degrees (we know that because there is a little square)
Angle LJG = 9x
Now lets set up the equation:
Angle HJW + Angle GLH + ANGLE LJG = 180 degrees
18 + 90 + 9x = 180
108 + 9x = 180
9x = 72
x = 8
So x = 8

Julia has determined that CE is perpendicular bisector of AB. The next step of a valid proof would be: B. AC = BC based on the perpendicular bisector theorem.
What is the Perpendicular Bisector Theorem?The perpendicular bisector theorem states that if a point is located on a segment (perpendicular bisector) that divides another segment into two halves, then it is equidistant from the two endpoints of the segment that is divided.
Thus, since Julia has determined that CE is perpendicular bisector of AB, therefore the next step of a valid proof would be: B. AC = BC based on the perpendicular bisector theorem.

A store manager was trying to figure out how many people did their shopping online compared to doing it in stores. To do this she polled several houses in the nearby neighborhoods. The results are shown below:
Based on the information presented can you infer anything about the number of people who did their shopping online vs. in-store?
Based off of this information, it looks like there are more online shoppers than in-store shoppers, more simply because there are 4 arrays that have more online shoppers than in-store shoppers, and 3 arrays that have more in-store shoppers than online shoppers, and 1 array that has an even amount of shoppers. But if you add up the numbers for a total of 160/161, you see there are more in-store shoppers than online shoppers.
So there are more in-store shoppers total.
Can the sides of a triangle have lengths 1, 3, and 4?
yes
OR
no
Answer:
No
Step-by-step explanation:
The 2 side lengths should be the same
Answer:
No
Step-by-step explanation:
In order for the sides to be able to create a triangle two of the given sides have to be greater than the third side once added together.
[tex]a+b > c[/tex]
[tex]1+3=4[/tex]
[tex]4=4[/tex]
Which means your answer is "no" these lengths do not create a triangle for it does not pass the Triangle Inequality Theorem.
Hope this helps.
Solve the system of equations:
x+3y-z=9
2x+9y+4z=12
x+4y+z=7
[i] … … … x + 3y - z = 9
[ii] … … … 2x + 9y + 4z = 12
[iii] … … … x + 4y + z = 7
Eliminate z by combining …
• … 4 times equation [i] and equation [ii] :
4 (x + 3y - z) + (2x + 9y + 4z) = 4•9 + 12
(4x + 12y - 4z) + (2x + 9y + 4z) = 36 + 12
6x + 21y = 48
2x + 7y = 16
• … equation [i] and equation [iii] :
(x + 3y - z) + (x + 4y + z) = 9 + 7
2x + 7y = 16
Since we ended up with 2 copies of the same equation, we have infinitely many solutions for x, y, and z. That is, we have infinitely many choices for x and y that satisfy 2x + 7y = 16, and consequently infinitely many choices for z to satisfy any of the 3 original equations.
We can parameterize the solution by letting, for instance, x = t; then the solution set is
x = t
2x + 7y = 16 ⇒ y = (16 - 2t)/7
x + 3y - z = 9 ⇒ z = t + 3 (16 - 2t)/7 - 9 ⇒ z = (t - 15)/7
where t is any real number.

Answer:
Step-by-step explanation:
First convert the mixed fractions to improper fractions.
[tex](5\dfrac{2}{3})^{2}-(4\dfrac{1}{3})^{2} = (\dfrac{17}{3})^{2} - (\dfrac{13}{3})^{2}[/tex]
We can use the identity a² - b² = (a +b)(a - b)
Here a = 17/3 and b = 13/3

We can add & subtract as they have common denominators.

Step-by-step explanation:
Analysing a company's fundamentals will tell you a stock's intrinsic value, as opposed to the value at which it is being traded. If the intrinsic value is more than the current share price, your analysis is showing that the stock is worth more than its price and that it makes sense to buy the stock.Help, please!!!

Answer:
The answer would be 11.3
Step-by-step explanation:
All you have to do is figure out how far one is from the other so from 7.8 I went back to 0 of course the Y coordinate stays the same. So then you get the -3.5 make it a positive so just 3.5 and then add to 7.8 to get 11.3

What is the equation of the line that passes through the point (-2, 7) and has a slope of zero?
FX-7
6 y = -2
H x = -2
y=7
Answer:
y = 7
Step-by-step explanation:
Linear equation: y = mx + b
where m is the slope and b is the y-intercept
If the line has a slope of zero, then: y = b
As the line passes through the point (-2, 7), then y = 7 since the y-coordinate of the point is 7

What is the y-intercept ??? Please show step by step!!
Answer:
(0, 1)
Step-by-step explanation:
The y-intercept is where a graph intersects with the y-axis. The x-coordinate would be 0, and the y-coordinate would be any real number.
Given the information above, the y-intercept is (0, 1) or 1 because its x-coordinate is 0 and y-coordinate is a real number.
Answer:
y-intercept is (0,1)
Step-by-step explanation:
When we are looking at the chart we’re looking for a point where the x is 0 and the y is 1 which is the definition of y-intercept, where the line intersects only with the y-axis
We can see this in the chart but if that point is not on there, we have another way to find it.
This is the formula, point-slope form.
(Math people are not that creative, you use it when you have the slop and a point)
First, we need to find the slope
We do this by taking two points and using the formula y2-y1 over (/) x2-x1
So our formula is y2-y1/x2-x1.
If you pick two random points, (We will use 0,1 and 1,3) and subtract them from each other, you have the slope
3 is y2 because it’s a y point and its the second point and 1 is our other point because its a y point and its the first y point
So our equation now is 3-1/x2-x1
Now we have to sub in for the x’s
Do the same thing and our equation now is…
3-1/1-0
This gets us to 2/1 which is obviously 2.
Now we have our slope so we just have to fill in for the point.
Point slope form uses the model y-y1=m(x-x1)
So we use our same two points and get
Y-1=2(x-0)
Solve this out to Slope intercept form which will give us our y-intercept.
This gets us to y=2x+1 so our y-intercept is clearly still 1!
