S 12x - 22 R 10x - 6 T 7x + 18
O X=8
O X=6
O X=4
O X=2
Answers
Answer:
x = 8
Step-by-step explanation:
In equilateral, the length of the sides are equal.
12x - 22 = 10x - 6
Add 22 to both the sides
12x = 10x - 6 + 22
12x = 10x + 16
Subtract '10x' from both sides,
12x -10x = 16
2x = 16
Divide both sides by 2
x = 16/2

Find all real solutions Tan pi/3 x-3=0
Answers
Step-by-step explanation:
If the question is like this,
[tex] \tan( \frac{\pi}{3}x - 3 ) = 0[/tex]
We take the arc tan of both sides.
[tex] \tan( - 1) ( \tan( \frac{\pi}{3}x - 3 ) = \tan {}^{ - 1} ( {}^{ }0 ) [/tex]
[tex] \frac{\pi}{3} x - 3 = 0[/tex]
[tex] \frac{\pi}{3} x = 3[/tex]
[tex] = \frac{9}{\pi} [/tex]
Since the period of a tan function, is pi, we divide pi by pi/3 since pi/3is the coeffeicent of the x variable
[tex] \frac{\pi}{ \frac{\pi}{3} } = 3[/tex]
So the answer is
[tex] \frac{9}{\pi} + 3n[/tex]
If this the question,
[tex] \tan( \frac{\pi}{3} x) = 3[/tex]
[tex] \frac{\pi}{3} x = 1.249[/tex]
[tex]x = \frac{3.747}{\pi} [/tex]
The period is once again 3 so we have
[tex] \frac{3.747}{\pi} + 3n[/tex]
where n is a interger.

again we have 4/9 and we see what we can put in to get another 36 , but we have a 9, so it’s 4. 4/9 x 4/4 = 16/36 when you divide this you them both you get 0.44 so they’re equivalent.
so 0.25 is less than 0.44
basically it’s saying 25<44
so 1/4 is less than 4/9

After 1 year, $15.00 * (1 + 5%) = $15.00 * 1.05
After 2 years, $15.00 * 1.05 * (1 + 5%) = $15.00 * 1.05²
After 7 days: $15.00 * 1.05⁷ = $21.11
What single percentage change is equivalent to a 9% increase followed by a 17% increase?
Answers
Answer:
27.53%
Step-by-step explanation:
Initial number = 100
9% increase
100*1.09= 109
17% increase
109*1.17= 127.53
The difference with the initial number is:
127.53 - 100 = 27.53
27.53/100*100% = 27.53%
This is the single percentage change

Which of the following functions has an initial value of 0 and a rate of change of 3?
Answers
The following function has an initial value of 0 and a rate of change of 3 will be y = 3x and it is shown in option (D) hence option (D) will be the correct answer.
How to graph a function?Drawing the graph of the appropriate function is the process of graphing a function.
Graphing simple functions like linear, quadratic, etc. is fairly easy, complex functions like rational, exponential, etc. require some skill and comprehension of certain mathematical thinking.
In other words graph of a function is a grammatical representation in the coordinate geometry.
Given that the function has a rate of change as 3
We know the rate of change is nothing but derivative so
dy\dx = 3
dy = 3dx
by integration
y = 3x + c now given that the initial value is zero so by putting x and y as 0.
c = 0
So the function is y = 3x so it is That the option (D) has the same behavior.

Peter is the owner of a hotel. He has found that when he charges the nightly cost of $139, the average occupancy is 275. In addition, Peter has found that with every $10 increase in the average nightly cost, the hotel occupancy decreases by an average of 22.
Which of the following functions describes the hotel's profit in terms of x, the number of $10 increases over $139?
Answers
Answer:
Without price increase, Cost/night = $119
Average occupancy = 372 The revenue will be 119*372 = $44,268
For every $15 price increase, the occupancy decreases by 25. Therefore with x price increases, The revenue will be $(119 + 15x)*(372 25x)
Cost/night = $119 + 15x Occupancy = 372 - 25x
Answer:
The nightly cost with x $15 price increases is $119 + 15x.
