Here is all the information you will need. Now, what you need to know is that ALL tangent, secant, cosecant, and cotangent functions have NO amplitudes. Also, keep in mind that although this IS the tangent graph, if you plan on writing your equation as a function of cotangent, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = cot\:\frac{1}{2}x,[/tex] in which you need to replase "tangent" with "cotangent", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the tangent graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cotangent graph [photograph on the right] is shifted [tex]\displaystyle \pi\:units[/tex] to the left, which means that in order to match the tangent graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \pi\:units,[/tex] which means the C-term will be positive, and perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\pi} = \frac{\frac{\pi}{2}}{\frac{1}{2}},[/tex] but we are NOT YET DONE. Although we shifted the graph back into position, remember, cotangent is graphed in REVERCE, so we need to insert a negative in front of the amplitude term, and with that, the cotangent graph of the tangent graph, accourding to the horisontal shift, is [tex]\displaystyle y = -cot\:(\frac{1}{2}x - \frac{\pi}{2}).[/tex] Now, with all that being said, we can move forward. To find the period in this case, you need to take a look at the distanse between each vertical asymptote. Now, accourding to this graph, the vertical asymptotes are [tex]\displaystyle -\pi = x\:and\:\pi = x.[/tex] From here, you will then find the distanse between these asymptotes by simply perfourming the operation of Deduction, and doing that will give you [tex]\displaystyle \boxed{2\pi} = \pi + \pi.[/tex] So, the period of this function is [tex]\displaystyle 2\pi.[/tex] Now, you will instantly get the jist of the horisontal shift by looking at the above formula. Just keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must pay cloce attention to what is given to you inside those parentheses. Finally, the midline is the centre of your graph, also known as the vertical shift, which in this case is at [tex]\displaystyle y = 0.[/tex]
Well, that just about wraps it up. Now that everything has been explained, you should understand it better. If you still have questions, do not hesitate to comment any you have.

C. infinitely many
Answers
Answer:
B one solution
Step-by-step explanation:
Answer:
B - one solution
Step-by-step explanation:
6x+8−2x(7−2)=2(6+1)
Subtract 2 from 7 to get 5.
6x+8−2x×5=2(6+1)
Multiply 2 and 5 to get 10.
6x+8−10x=2(6+1)
Combine 6x and −10x to get −4x.
−4x+8=2(6+1)
Add 6 and 1 to get 7.
−4x+8=2×7
Multiply 2 and 7 to get 14.
−4x+8=14
Subtract 8 from both sides.
−4x=14−8
Subtract 8 from 14 to get 6.
−4x=6
Divide both sides by −4.
x=−46
Reduce the fraction −46 to lowest terms by extracting and canceling out 2.
x=−23

5. Mrs. Perkins hosts a birthday party for her son and 7 guests. She orders 2 cookies and a
cupcake for each child. The cost of the cupcake is $2.75, and the total bill is $46.00. What is the
cost of a cookie?
Answers
Answer:
Below.
Step-by-step explanation:
In total there are 8 kids. Each cupcake is 2.75 so 8x2.75= 22 now the total is 46.00 So? 46-22 = 24. 24 divided by 2 = 12.
I Divided by 12 because they said cost of each individual cookie.
Answer:
$1.375
Step-by-step explanation:
7guests + 1son = 8children
8 (children) x 2.75 (dollars-per-cupcake) = 22
46 (total cost) - 22 (dollars spend on cupcakes) = 24
24 (left) / 16 (number of cookies needed (each child gets two)) = 1.375
Your college professor tells you he will give you a 30%-30%-40% split on grades between homework, quizzes, and test. However which ever category you have the highest average and will be able to 40% category. What will your final grade be if your homework average of 62, your quiz average is 93, and your test average 60?
Answers
Here we want to calculate percentages of different values to find your final grade, we can conclude that your final grade will be 73.8
We know that:
you have an average of 62 in homework
you have an average of 93 on quiz
you have an average of 60 on test.
Your final grade will be a 30%-30%-40% of the above average scores, such that the 40% will be of the highest average.
We can see that the highest one is on quiz, then your final grade will be:
the 40% of your average quiz grade plus the 30% of your average homework grade plus the 30% of your average test grade.
This will be:
[tex]g = \frac{40 \%}{100 \%}*93 + \frac{30 \%}{100 \%}*62 + \frac{30 \%}{100 \%}*60\\\\g = 0.4*93 + 0.3*62 + 0.3*60 = 73.8[/tex]
We can conclude that your final grade will be 73.8

A new cars salesperson, sold an average of $32,130 per day for the first 4 days she worked. The next 5 days she worked, she sold an average of $31,173. How much did she sell on average per day over the entire time she worked??
Answers
Answer:
$31,598.33
Step-by-step explanation:
she worked 4+5=9 days.
due the total average we need the total of sales and divide it by the length of the observation period (9 days).
how much did she sell in total on the first 4 days ?
well, the average times 4 = 32130×4 = $128520
how much did she sell in total during the following 5 days ?
31173×5 = $155865
so, the daily average is
($128520 + $155865) / 9 =$284385 / 9 = $31,598.33

a tank is 4÷5 full of water. after drawing off 190 litees of water,it is just 1÷6 full. what is the capacity of the tank
Answers
Hey there! I'm happy to help!
Let's have the capacity be c. The tank is currently at 4/5c. We subtract 190 and then we are at 1/6c. Let's set this up as an equation and solve it.
4/5c-190=1/6c
We want to get the c all by itself to see the capacity of the tank. Let's get all of the c values on the left side of the equation and the numbers on the right by using inverse operations.
4/5c-190=1/6c
Add 190 to both sides.
4/5c=1/6+190
Subtract 1/6 from both sides.
19/30c=190
Divide both sides by 19/30.
c=300
So, the capacity of the tank is 300 liters of water.

Answers
you can solve the equestion by many rules , but in my point of view the easiest rule is subtraction/addition and subtition method .
Ans X=11.5
Y = -39
8x+2y=14 eqn.......1
82+2y=4 eqn .......2
2y= -78 (4-82)
y = - 39
putting value of y in eqn ..1
we get,
8x+ 2×(-39) =14
8x= 14+78
8x=92
x = 92÷8
x=11.5
it's a subtition method..
