The equivalent angle in the interval [0, 2pi] is 5pi/6.
How to find the equivalent angle?
Remember that for any given angle θ in radians, we define a family coterminal or equivalent angles as:
A = θ + n*(2pi)
Where n is a whole number.
Now we want to find an angle equivalent to 17pi/6 that is on the range between 0 and 2pi.
Then we can write:
A = 17pi/6 + n*(2pi)
If we use n = -1, then we get:
A = 17pi/6 - 2pi = 17pi/6 - 12pi/6 = 5pi/6
This is the equivalent angle in the desired range.

If tan theta = 2ab / a2-b2 then find all other trigonometric ratios
Answer:
[tex]\displaystyle{\sin \theta = \dfrac{2ab}{a^2+b^2}}\\\\\displaystyle{\cos \theta = \dfrac{a^2-b^2}{a^2+b^2}}\\\\\displaystyle{\csc \theta = \dfrac{a^2+b^2}{2ab}}\\\\\displaystyle{\sec \theta = \dfrac{a^2+b^2}{a^2-b^2}}\\\\\displaystyle{\cot \theta = \dfrac{a^2-b^2}{2ab}}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle{\tan \theta = \dfrac{2ab}{a^2-b^2}}[/tex]
To find other trigonometric ratios, first, we have to know that there are total 6 trigonometric ratios:
[tex]\displaystyle{\sin \theta = \sf \dfrac{opposite}{hypotenuse} = \dfrac{y}{r}}\\\\\displaystyle{\cos \theta = \sf \dfrac{adjacent}{hypotenuse} = \dfrac{x}{r}}\\\\\displaystyle{\tan \theta = \sf \dfrac{opposite}{adjacent} = \dfrac{y}{x}}\\\\\displaystyle{\csc \theta = \sf \dfrac{hypotenuse}{opposite} = \dfrac{r}{y}}\\\\\displaystyle{\sec \theta = \sf \dfrac{hypotenuse}{adjacent} = \dfrac{r}{x}}\\\\\displaystyle{\cot \theta = \sf \dfrac{adjacent}{opposite} = \dfrac{x}{y}}[/tex]
Since we are given tangent relation, we know that [tex]\displaystyle{y = 2ab}[/tex] and [tex]\displaystyle{x = a^2-b^2}[/tex], all we have to do is to find hypotenuse or radius (r) which you can find by applying Pythagoras Theorem.
[tex]\displaystyle{r=\sqrt{x^2+y^2}}[/tex]
Therefore:
[tex]\displaystyle{r=\sqrt{(a^2-b^2)^2+(2ab)^2}}\\\\\displaystyle{r=\sqrt{a^4-2a^2b^2+b^4+4a^2b^2}}\\\\\displaystyle{r=\sqrt{a^4+2a^2b^2+b^4}}\\\\\displaystyle{r=\sqrt{(a^2+b^2)^2}}\\\\\displaystyle{r=a^2+b^2}[/tex]
Now we can find other trigonometric ratios by simply substituting the given information below:
[tex]\displaystyle{x = a^2-b^2}[/tex][tex]\displaystyle{y = 2ab}[/tex][tex]\displaystyle{r = a^2+b^2}[/tex]Hence:
[tex]\displaystyle{\sin \theta = \dfrac{y}{r} = \dfrac{2ab}{a^2+b^2}}\\\\\displaystyle{\cos \theta = \dfrac{x}{r} = \dfrac{a^2-b^2}{a^2+b^2}}\\\\\displaystyle{\csc \theta = \dfrac{r}{y} = \dfrac{a^2+b^2}{2ab}}\\\\\displaystyle{\sec \theta = \dfrac{r}{x} = \dfrac{a^2+b^2}{a^2-b^2}}\\\\\displaystyle{\cot \theta = \dfrac{x}{y} = \dfrac{a^2-b^2}{2ab}}[/tex]
will be other trigonometric ratios.
The probability for event A is 0.3, the probability for event B is 0.6, and the probability of events A or B is 0.8.
Why are the events not mutually exclusive
The events are not mutually exclusive because P(A or B) is not equal to P(A) + P(B)
Why are the events not mutually exclusive?The probability values are given as:
P(A) = 0.3
P(B) = 0.6
P(A or B) = 0.8
For mutually exclusive events, we have:
P(A or B) = P(A) + P(B)
Substitute the known values in the above equation
P(A or B) = 0.3 + 0.6
Evaluate the sum
P(A or B) = 0.9
From the given parameters, we have
P(A or B) = 0.8
Hence, the events are not mutually exclusive because P(A or B) is not equal to P(A) + P(B)

And according to this,
The probability P is
P(Club) = 13/52 = 1/4
P(Ten) = 4/52 = 1/13
P(Club and Ten) = (1/4)(1/13) = 1/52

3 bells ring at interval of 12,15 and 18 minutes.Respectively they all ring together at 6am,at what time will they ring together? again?
The least common multiple of two or more natural numbers is the least common multiple of all of them. This concept has historically been linked to natural numbers, but can be used for negative integers or complex numbers.
We calculate the least common multiple, by simultaneous decomposition, this method consists of extracting the common and non-common prime factors, therefore
The lcm of 12,15, 1812 - 15 - 18 | 2 6 - 15 - 9 | 2 3 - 15 - 9 | 3 1 - 5 - 3 | 3 1 - 5 - 1 | 5 1 - 1 - 1 |L.c.m.(12,15,18)= 2² × 3² × 5 = 180 min
The least common multiple of 12, 15, and 18 is 180.
Convert the minutes to hours, for this we apply the rule of 3:
x = 180 * 1 / 60 = 3 hrAs the bells all together ring at 6 am, so we add
6 a.m + 3 = 9Answer: The bells are rung together again at 9 in the morning.
Find the extremum of f(x,y) subject to the given constraint, and state whether it is a maximum or a minimum. f(x,y)=xy; 6x y=10
There is a maximum value of 7/6 located at (x, y) = (5/6, 7).
The function given to us is f(x, y) = xy.
The constraint given to us is 6x + y = 10.
Rearranging the constraint, we get:
6x + y = 10,
or, y = 10 - 6x.
Substituting this in the function, we get:
f(x, y) = xy,
or, f(x) = x(10 - 6x) = 10x - 6x².
To find the extremum, we differentiate this, with respect to x, and equate that to 0.
f'(x) = 10 - 12x ... (i)
Equating to 0, we get:
10 - 12x = 0,
or, 12x = 10,
or, x = 5/6.
Differentiating (i), with respect to x again, we get:
f''(x) = -12, which is less than 0, showing f(x) is maximum at x = 5/6.
The value of y, when x = 5/6 is,
y = 12 - 6x,
or, y = 12 - 6*(5/6) = 7.
The value of f(x, y) when (x, y) = (5/6, 7) is,
f(x, y) = xy,
or, f(x, y) = (5/6)*7 = 7/6.
Thus, there is a maximum value of 7/6 located at (x, y) = (5/6, 7).

Answer:
The hand moved [tex]\bf \frac{3}{4}[/tex] of a complete turn.
Step-by-step explanation:
The hand moved from 3 to 12, that is, it moved:
12 - 3 = 9 hours
In a clock, 12 hours represent a complete turn.
∴ Using the unitary method:
12 hours ⇒ 1 turn
1 hour ⇒ [tex]\frac{1}{12}[/tex] turns
9 hours ⇒ [tex]\frac{1}{12}[/tex] × 9 = [tex]\frac{9}{12}[/tex]
= [tex]\bf \frac{3}{4}[/tex] turns (simplified)
∴ The hand moved [tex]\bf \frac{3}{4}[/tex] of a complete turn.
The answer is [tex]\boxed{\frac{3}{4}}[/tex].
To find the fraction of a complete turn it moved in this case, take the ratio between hours covered between 3 and 12, and the hours covered in a complete turn.

A cupcake store has 5 different kinds of cupcakes: chocolate, vanilla, lemon, strawberry, and coffee. Assuming there are at least 12 of each kind of cupcake, how many ways can you choose 12 cupcakes
Assuming there are at least 12 of each kind of cupcake, number of ways can you choose 12 cupcakes is; 1399358844975 ways
How to solve probability combination?We are given the quantity of each type of cupcake as follows;
Number of types of cupcakes = 5
Number of Chocolate Cupcakes = 12
Number of Vanilla Cupcakes = 12
Number of Lemon cupcakes = 12
Number of Strawberry Cupcakes = 12
Number of coffee cupcakes = 12
Thus, total number of cupcakes will be gotten by adding all the quantities given above of the different types of cupcakes and we will get; Total number of cupcakes = 12 + 12 + 12 + 12 + 12
Total number of cupcakes = 60
Now, since there is no order of selection, then the number of ways that you can choose 12 cupcakes will be gotten by using the combination formula which is; nCr = n!/(n!(n - r)!)

What is the equation for the line of best fit on the scatter plot below?
Answer:
The correct answer is the third option: y = 4x - 20
Step-by-step explanation:
To solve this problem, we should first find two points that are located along our line of best fit. We can see that the points (25,80) and (15, 40) are both located along the line. Next, we can calculate the slope using these two points.
slope = rise/run = Δy/Δx = (80-40)/(25-15) = 40/10 = 4
Therefore, the slope of the line of best fit is 4.
To find the y intercept, we can use our equation for slope and plug in one of our points.
y = mx + b
y = 4x + b
40 = 4(15) + b
40 = 60 + b
b = -20
Therefore, the y intercept is -20.
If we put both our slope and y intercept into one equation, we get:
y = mx + b
y = 4x - 20
