[tex]\left[\begin{array}{ccc}cosx=0\\sinx=1\end{array} \ = > \ \left[\begin{array}{ccc}x=\frac{\pi }{2} +\pi k\\x=\frac{\pi }{2} +2\pi n\end{array}[/tex]
where n,k∈Z;
2) if x∈[0;2π], then x=π/2; 3π/2.
Note, the greek letter 'Θ' is replaced with 'x'.
Answer:
π/2, 3π/2
Step-by-step explanation:
Given :-
0 ≤ θ < 2πTo Solve :-
cosθ = cotθSolving :-
cosθ = cotθcosθ = cosθ/sinθ1 = 1/sinθsinθ = 1θ = π/2, 3π/23. A playground designer wanted to place a fountain so that it was close to both the slide and the swings.
Refer to the coordinate grid shown. Each unit on the grid represents 5 ft.
(a) Find the distance from the fountain to the slide. Show your work.
(b) Find the distance from the fountain to the swings. Show your work.
Answer:
Part A:
10ft
Part B:
35ft
Step-by-step explanation:
• Since we know that an increase of 1 on either the x, or y value is equal to 5 feet, we can form an equation where x = the amount that the value increased, so since the fountain is at (-2, -2) and the slide is at (-2, 0), we see that there is an increase of 2 to the y-value, meaning our equation should now be 5(2) which equals 10.
• Because we use 5x and 5y to solve this, we can already see how to do this. If the swings are at (5, -2) and the fountain is at (-2, -2), we can see that there was an increase of 7 on the x-value, meaning that our equation would now be 5(7), which equals 35.
In a given school, there 240 boys and 260 girls.

[tex]\\ \rm\Rrightarrow \dfrac{260}{240}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{13}{12}[/tex]

Total pupils=240+260=500Ratio
[tex]\\ \rm\Rrightarrow \dfrac{240}{500}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{12}{25}[/tex]
[tex]\\ \rm\Rrightarrow 12:25[/tex]
Answer:
a) 13:12
b) 12:25
Step-by-step explanation:
a) ratio of girls to boys
260:240 or 13:12
b) ratio of boys to the total number of pupils
240:(240+260) or 240:500 or 12:25
The basic way to find this is by simplifying.

Matthew bought 2 movie tickets for $11, and Rosa bought 7 movie tickets for $38.50. What is the constant of proportionality?
Answer:
You should multiply 5.5 by 7 and it is equal to 38.5 so it is D
explanation:
did the test hope this helps! :D
The constant of proportionality of the given condition is 5.5.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Let's say Matthew and Rosa's constant of proportionality is K.
Now,
Matthew bought 2 movie tickets for $11.
So,
11 ∝ 2
11 = K 2 ⇒ K = 5.5
Now,
Rosa bought 7 movie tickets for $38.50.
So,
38.50 ∝ 7
38.50 = K 7 ⇒ K = 5.5
Hence "The constant of proportionality of the given condition is 5.5".

There are 150 males and 50 females participating in a marathon. What percent of the participants are female?
Hey there!
Answer: 25% of participants are females
Add both M and F = 200
50 + 50 + 50 + 50 = 200
=> 50 + 150 = 200
each 50 is 25% of 200
Therefore, the percentage of females in the race is 25%
Answer:
50+150=200
female=50
50÷200×100=25%
percentage of female=25%

what is 5/8 + 1/12? and how do you do it?
The answer to your question is 17/24
First find the lcd which is 24
5/8 = Times eight by three to get 23 = And whatever you do to the top you do to the bottom = So then you would do five times three to get 15 = To create your new fraction 15/24
1/12 = Times twelve by two to get 24 = And whatever you do to the top you do to the bottom = So then you would do one time two to get 2= To create your new fraction 2/24
Then you would add 15/24+2/24= 17/24

Answer:
B) 1 8/27
Step-by-step explanation:
First, change all mixed fractions into improper fractions:
2 1/3 = 7/3
1 4/5 = 9/5
7/3 ÷ 9/5
Next, flip the second fraction, and change the division sign into multiplication:
7/3 x 5/9
Multiply across:
7/3 x 5/9 = 35/27
Change into a mixed fraction:
35/27 = 27/27 + 8/27
1 8/27 is your answer.

Answer:
4x³
Step-by-step explanation:
d/dx ln(x⁴ + 7) = 1/(x⁴ + 7) × _?
To obtain the missing expression, let us simplify d/dx ln(x⁴ + 7). This can be obtained as follow:
Let y = ln (x⁴ + 7)
Let u = (x⁴ + 7)
Therefore,
ln(x⁴ + 7) = ln u
Thus,
y = ln u
dy/du = 1/u
Next, we shall determine du/dx. This is illustrated below:
u = (x⁴ + 7)
du/dx = 4x³
Finally, we shall determine dy/dx of ln (x⁴ + 7) as follow:
dy/dx = dy/du × du/dx
dy/du = 1/u
du/dx = 4x³
dy/dx = 1/u × 4x³
But:
u = (x⁴ + 7)
Therefore,
dy/dx = 1/(x⁴ + 7) × 4x³
Thus, the missing expression is 4x³

Answer:
A. 2/(1 -x)²
Step-by-step explanation:
The derivative of a ratio is given by the formula ...
d(u/v) = (v·du =u·dv)/v²
Here, we have ...
u = 1+x; du = 1·dx
v = 1 -x; dv = -1·dx
Then ...
[tex]dy=\dfrac{(1-x)(dx)-(1 +x)(-dx)}{(1-x)^2}\\\\\dfrac{dy}{dx}=\dfrac{1-x +1+x}{(1-x)^2}=\boxed{\dfrac{2}{(1-x)^2}}[/tex]

Answer:
(2x-10) +x +(x+10) = 180x = 45(2x-10)° = 80°(x+10)° = 55°x° = 45°Step-by-step explanation:
The equation is an expression of the fact that the sum of the angles in a triangle is 180°.
(2x -10)° +x° +(x +10)° = 180°
For the purposes of the answer box, I'd leave off the degree symbol:
(2x -10) +x +(x +10) = 180
__
This simplifies to ...
4x = 180
x = 45
Then the angles (CW from top) are ...
(2·45 -10) = 80°
(45 +10)° = 55°
(45)° = 45°
The cost of parking a car in an hourly lot can be

parking?
Select one:
You can only park for 2 hours
O
It costs 5 dollars to park all day
O
There is a 52 fee to park, before the number of
hours are factored in
The hourly rates $2
Answer:
C. There is a $2 fee to park, before the number of hours are factored in.
Step-by-step explanation:
Given that the equation, [tex] y = 3x + 2 [/tex], represents total cost charged for at a parking lot for customers to park their car, thus:
the "x" represents the number of hours,
3 represents the charged fee per hour
2 represents the flat fee charged, which is the starting fee, before the number of hours is calculated and added.
Therefore, the answer is "C. There is a $2 fee to park, before the number of hours are factored in."

Answer:
y = 6x + 4
Step-by-step explanation:
We know the equation is linear. First, use two points to find the slope of the line.
m = (y₂ − y₁) / (x₂ − x₁)
m = (10 − 4) / (1 − 0)
m = 6
The y-intercept is 4. So the equation of the line is:
y = mx + b
y = 6x + 4

What is the image of (0, -8) after a reflection over the line y = -x?
Submit Answer
Answer:
(8,0)
Step-by-step explanation:
could be negative 8 but it said positive 8
positive works
The required reflection of the point (0, -8) on the line y = -x is (8, 0).
To determine the image of (0, -8) after a reflection over the line y = -x.
the equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
For the image of the point of the line y = -x
The reflection of point (0, - 8) is given as by swaping the value and change the sign, So the image of the point is (8, 0).
Thus, the required reflection of the point (0, -8) on the line y = -x is (8, 0).
