What are periodic functions?A periodic function has a range that is determined for a fixed interval and a domain that includes all real number values.
Any function that has a positive real integer p such that f (x + p) = f (x), with all x being real values, is said to be periodic.
Given, A trigonometric function [tex]\frac{cot^2x}{1 + cot^2x}[/tex],
Now, Using different trig identities we have,

Subtract the sum of 9 3/4 and 3 1/8 from 18 7/16
help pls
Answer:
-26/25
Step-by-step explanation:
I took the quiz and I got an A+
Answer:
5 7/16
Step-by-step explanation:
First off, make all the numbers have the same denominator.
In this case, the best one would be 16.
For 9 3/4, the four goes into 16 four times. So you multiply the 3 by four, and get 12 in the numerator. So it is now 9 12/16.
Next we have 3 1/8. 8 goes into 18 2 times. So you multiply 1 by 2 and get 2 in the numerator. So it is now 3 2/16.
Now, lets add the two together:
3 2/16+9 12/16 =
12 14/16
Now we know the sum of the two numbers.
Lets subtract this from 18 7/16:
18 7/16-12 14/16
=
5 7/16
This is your answer!

Solve the following quadratic equation for all values of x in simplest form.
4(x 2−5)−1=3
The solutions to the equation 4(x² − 5) − 1 = 3 are ±√6
How to determine the solutions to the equation?From the question, we have the following parameters that can be used in our computation:
4(x 2−5)−1=3
Express properly
This gives
4(x² − 5) − 1 = 3
Subtract -1 from both sides of the equation
So, we have the following representation
4(x² − 5) = 4
Divide both sides by 4
This gives
x² − 5 = 1
Subtract -5 from both sides of the equation
So, we have the following representation
x² = 6
Take the square root of both sides
x = ±√6
Hence, the solution is ±√6

The distance of the ship from lighthouse found using sine law at both locations are 14.12 miles and 4.8 miles.
What is sine law?
The sine law asserts that the ratio of a triangle's side length to the sine of its opposing angle, which is constant for all three sides.
From the given figure we can find θ = 30 - 10 = 20°
According to sine law, we can write the following equation,
[tex]\frac{9.6}{sin \theta} = \frac{x}{sin \angle ABL} = \frac{y}{sin \angle LAB} \\[/tex]
From the figure, we get that ∠LAB= 10° (alternate angles)
∠LBC = 30°
∠ABL = 180 - 30 = 150°
θ = 20°
Substituting above values in the equation we get ,
[tex]\frac{9.6}{sin 20} = \frac{x}{sin 150} = \frac{y}{sin 10} \\\\\frac{9.6}{0.34} = \frac{x}{0.5} = \frac{y}{0.17}[/tex]
Solving the above we get,
x = 14.12
y = 4.8
Therefore the ship began 14.12 miles from the lighthouse and after travelling 9.6 miles south it is at 4.8 miles from the lighthouse.

How much more interest would be earned on a 100,0000 CD for 9 months than for 6 monthd
There is a $1,000 additional interest earned on a $100,000 CD (Commercial Paper) for 9 months than for 6 months.
How is the additional interest determined?The additional interest earned for a 9-month CD over a 6-month CD can be computed using the subtraction operation.
Firstly, the interests on the 9-month CD and 6-month CD are worked out separately, using the interest formula: Principal x Rate x Time.
The interest for the 6-month CD is subtracted from the interest for the 9-month CD. The result is the difference or additional interest earned.
Commercial Deposit = $100,000
Annual Percentage Rate = 4%
Monthly Percentage Rate = 0.333% (4%/12)
Interest for 9 months = $3,000 ($100,000 x 4% x 9/12)
Interest for 6 months = $2,000 ($100,000 x 4% x 6/12)
The difference in interest earned = $1,000 ($3,000 - $2,000) or ($100,000 x 4% x 3/12)

Is the vertex of -x^2q-2x+10=0 parabola a maximum value or minimum value?
The vertex of the parabola -x² - 2x + 10 = 0 occurs at (-1,11), It is a maximum value.
Determine whether the parabola is maximum value or minimum value?Given the equation of the parabola;
-x² - 2x + 10 = 0
First, the maximum of a quadratic function occurs at;
x = -b/a, if a is negative, the maximum value of the function is f( -b/2a)
f_max(x) = ax² + bx + c occurs at;
x = -b/2a
Now, find the value of x = -b/2a
Plug in a = -1 and b = -2
x = -( -2/2(-1) )
x = -( -2/-2) )
x = -( 1 )
x = -1
Hence;
f(x) = -x² - 2x + 10
f( -1 ) = -( -1 )² - 2( -1 ) + 10
f( -1 ) = -1 + 2 + 10
f( -1 ) = -1 + 12
f( -1 ) = 11
Therefore, maximum occurs at (-1,11).

x+y=8
x-y=4
x=? y=?
Answer:
Step-by-step explanation:
To solve this system of equations, you can use the substitution method.
In this method, you solve one of the equations for one of the variables in terms of the other variable. Then you substitute this expression into the other equation. This will give you a single equation in one variable, which you can solve to find the value of that variable. Finally, you can substitute this value back into one of the original equations to find the value of the other variable.
To solve this system using substitution, we can solve the second equation for y:
y = x - 4
Then, we substitute this expression for y in the first equation:
x + (x - 4) = 8
Combining like terms, we get:
2x - 4 = 8
Adding 4 to both sides, we get:
2x = 12
Dividing both sides by 2, we find that:
x = 6
Now we can substitute this value back into one of the original equations to find the value of y. Let's substitute it into the second equation:
x - y = 4
Substituting 6 for x, we get:
6 - y = 4
Subtracting 6 from both sides, we find that:
y = 2
So the solution to the system of equations is x = 6 and y = 2.
Answer:
x=6, y = 2
Step-by-step explanation:
If you add 2 expressions, 2x = 12, so x = 6.
So the other one y = 2.

Step-by-step explanation:
to find median you put the numbers in order from least to greatest then you see what number is in the middle
Answer:
98Step-by-step explanation:
The median of an information set is found by putting the information set in ascending numerical order and identifying the center number. If there are an odd number of data values within the data set, the median could be a single number. If there are an excellent number of data values within the data set, the median is that the average of the 2 middle numbers. Sorting the information set for the values entered above we have:
98, 67, 98, 102, 74, 95, 99
Since there's an odd number of data values during this data set, there's just one middle number. With 7 data values, the center number is that the data value at position 4. Therefore, the median is 98.

On solving the provided question we can say that - The number of times the geometric figure maps onto itself during a 360° rotation is the order of rotational symmetry.
What is the order of rotation?The order of rotational symmetry is the maximum number of rotations that a geometry may fit in. 360°A°, where A° is the smallest angle by which a figure may be rotated from its rotated shape to match its original shape, represents the degree of rotational symmetry. (180 degrees) A shape's degree of rotational symmetry is determined by how many times a perfect circle may be turned while maintaining its appearance. Only when a triangle is back in its original beginning position will a full 360° revolution appear the same.
