What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
A function is said to increasing if the value of y increases as the value of x increases.
From the graph, the function is increasing on (−∞,−9),(-6,-2) and (3,7)
The local minima is a point where the function has minimum value in its local neighbour.
From the graph, the function has a local minima at x=-6 and at x=3.
In the end, the value of f(x) decreases as the value of x increases therefore the sign of the function's leading coefficient is negative.
The graph intersects the x-axis 2 times and also the function have 5 turning points both the these information indicates that the function is of 5 degrees or 7 degrees.
Therefore, interval, local minima, coefficient value and degree of function is obtained.

Based on a system of equations, the investment at each rate is as follows:
At 7% = $5,000At 11% = $1,000.What is a system of equations?A system of equations, also known as simultaneous equations, yields the solutions to two or more equations solved concurrently or simultaneously.
We use the let statements to state the variables of simultaneous equations.
The total investment = $6,000
The total interest earned = $460
Interest rates:
A = 7%
B = 11%
Let investment A = a and investment B = b
Equations:0.07a + 0.11b = 460 ... Equation 1
a + b = 6,000 ... Equation 2
Multiply Equation 2 by 0.07:
Equation 3: 0.07a + 0.07b = 420
Subtract Equation 3 from Equation 1:
0.07a + 0.11b = 460

Relationships between short- and long-term exposure to violent video games and desensitization, as measured through components of moral evaluation, were examined. Sixty-six children aged 5-12 years old completed questionnaires assessing video game experience and preferences and empathy and attitudes toward violence. The children played a violent or nonviolent video game and then responded to vignettes about everyday occurrences. Vignette responses were coded for aggression and empathy. Preexisting empathy and attitudes towards violence were positively related to the corresponding vignette scores. Long-term exposure to violent video games contributed to lower empathy vignette scores. Playing a violent versus a nonviolent game did not affect vignette responses. Results suggest that long-term exposure to violent video games may be associated with desensitization as reflected in lower empathy, although the direction of causality remains unclear.What is the main IV?What is the main DV?

The slope is negative three halves, and the y-intercept is 8. The candle starts at a height of 8 inches and decreases three halves of an inch every hour.
The correct statement regarding the slope and the intercept of the linear function are is given as follows:
The slope is negative two thirds, and the y-intercept is 8. The candle starts at a height of 8 inches and decreases two thirds of an inch every hour.
How to interpret the y-intercept of a linear function?The two most important features of a linear function are the slope and the intercept, and their meaning is explained as follows:
Slope: rate of change of the output variable relative to the input variable.Intercept: value assumed by the output variable when the input variable assumes a value of zero.The input and output variables for this problem are given as follows:
Input: time in hours.Output: height in inches.Two points of the function are:
(0, 8) and (3,6).
Given two points, the slope is calculated as the change in y divided by the change in x, hence:
m = (6 - 8)/(3 - 0)
m = -2/3.
Meaning that the candle's height decays at a rate of 2/3 of an inch an hour.
When x = 0, y = 8, hence the intercept of b = 8 represents the initial height of the candle.

All, 25%, and 5 are all valid options that can be selected in the Top Values list for a query.
All will display all the values in the query, 25% will display the top 25% of the values, and 5 will display the top 5 values.
To calculate 25%, we can use the formula (value/total)*100. For example, if the total number of values is 20, then 25% would be (20/20)*100 = 100. This would display all 20 values in the query. Similarly, if the total number of values is 50, then 25% would be (50/50)*100 = 100, which would also display all 50 values.
To calculate 5, we can use the same formula (value/total)*100. For example, if the total number of values is 20, then 5 would be (5/20)*100 = 25. This would display the top 5 values in the query. Similarly, if the total number of values is 50, then 5 would be (5/50)*100 = 10, which would also display the top 5 values.

The value of g becomes 64% of its value on the surface of the earth when it is at a height of 3200km above the surface, with the radius of the earth being 6400km.
Radius of Earth = 6400 km
Height above the surface of Earth = 3200 km
Gravitational Acceleration on surface of Earth = 9.8 m/s2
Gravitational Acceleration at 3200 km above the surface of Earth = 9.8 x 0.64 = 6.272 m/s2
The gravitational acceleration (g) on the surface of the earth is 9.8 m/s2. This value is constant, regardless of the height of an object above the surface. However, as the height of an object increases, the gravitational force experienced by the object decreases. The radius of the earth is 6400 km, so at a height of 3200 km above the surface, the gravitational acceleration experienced by an object is 64% of its value on the surface of the earth, which is 6.272 m/s2. This is because the gravitational force decreases as the object moves further away from the surface, and at 3200 km the force is only 64% of the force at the surface.

Mariam wants to rent out her house. She researches similar listings in an online rental marketplace and sees that she can rent her home for $210$ per night or $1300 per month. Mariam's house is near a beach in a moderate-sized city with good weather year-round, a famous aquarium, a water park, and lots of restaurants.
To figure out if she should list her home as a short-term rental or a long-term rental, first Mariam divides 1300 by 210.
1300/210=6.2
She needs to rent her home 6-7 nights per month to match the revenue from a long-term rental. Since Mariam lives in a location likely to have tourists, she should find plenty of renters. She lists her home as a short-term rental.
In her reasoning, Mariam divided 1300 by 210. If this is correct, explain why. If this is not correct, explain what she should have done.
This is absolutely correct as dividing the rate per month by the rate per night gives the number of nights per month needed for the revenues to match: [tex]$$month$\div $night=r/month \cdot \ $night/r$=# $nights/month$$[/tex]

[tex]1.\; -8x^3y^5\\\\2\; \dfrac{2y^3}{3}\\\\3.\; They are both equal\\\\4.\; 3x^2\\\\[/tex]
Step-by-step explanation:
First let's understand what an exponent is.
When a number or a term or an expression is multiplied repeatedly by itself, an exponent can be used to represent this situation
for example,
5 x 5 x 5 x 5 x 5 x 5 = 5⁶ since 5 is multiplied by itself 6 times
Here the number being multiplied(5) is called the base and the number of times it is multiplied(6) is called the exponent.
There are some rules regarding exponentiation
1 Zero Exponent
Any number raised to the power zero is 1
[tex]4^0 = 1\\\\123.456^0 = 1\\\\x^0 = 1[/tex]
2. Negative Exponent
If the exponent if negative, the expression is equivalent to the reciprocal of the term raised to the positive exponent
In general
[tex]a^{-m} = \dfrac{1}{a^m}\\\\and\\\\\dfrac{1}{a^{-m}} = a^m\\\\[/tex]
Examples:
[tex]x^-1 = \dfrac{1}{x}\\\\\left({x + y}\right)^{-a} = \dfrac{1}{(x+y)^a}[/tex]
[tex]\dfrac{1}{x^{-3}} = x^3[/tex]
3. Product Rule
When you multiply exponents with the same base the exponents get added
In general
[tex]\displaystyle {a^m a^n = a^{m + n}}[/tex]
Examples
[tex]x^3x^6 = x^{(3+6)} = x^9\\\\[/tex]
4. Quotient Rule
When you divide an exponentiated term by another exponentiated term with the same base the resulting exponent is the difference between the two exponents:
In general
[tex]\dfrac{a^m}{a^n} = a^{m-n[/tex]
Examples
[tex]\dfrac{y^3}{y^2} = y^{3-2} = y^1 = y[/tex]
5. Power Rule 1
An exponent term raised to another power will be the base raised to the product of the two exponents
In general
[tex](a^m)^n = a^{mn}[/tex]
[tex](x^3)^4 = x^{3 \cdot 4} = x^{12}[/tex]
6. Power Rule 2
If the base is the product of two or more terms and the whole expression is raised to a power then each individual term gets raised to that power.
[tex](ab)^m = a^mb^m\\\\(2x^3y^2z^4)^4 = 2^4x^{3.4}y^{2.4}z^{4.4} = 16x^{12}y^8z^{16}[/tex]
7. One exponent
Any term raised to the power 1 is itself
[tex]a^1 = a[/tex]

What is the Pythagorean theorem?
Pythagoras Theorem (also called Pythagorean Theorem) is an important topic in Mathematics, which explains the relation between the sides of a right-angled triangle. The sides of the right triangle are also called Pythagorean triples. Pythagoras theorem is basically used to find the length of an unknown side and the angle of a triangle. By this theorem, we can derive the base, perpendicular and hypotenuse formulas.
Pythagoras formula:-
Hypotenuse² = Perpendicular² + Base²
c² = a² + b²
Where “a” is the perpendicular,
“b” is the base,
“c” is the hypotenuse
Now,
For given situation,
Hypotenuse=10feet, perpendicular=2.5feet and we have to find base

What is a congruent triangle?
Two triangles that are congruent will have precisely the same three sides and three angles.
The dimensions of the triangles' sides and angles determine whether two or more triangles are congruent. A triangle's size is determined by its three sides, and its shape by its three angles. Pairs of corresponding sides and corresponding angles in two triangles are said to be equal if they are congruent. They share a similar size and shape. In triangles, there are numerous congruence conditions.
The triangles are congruent by SAS congruency because
AC = CD (Given)
∠ACB = ∠DCE ( Vertically opposite angles)
BC = CE (Given)
Thus, Triangle ABC ≅ Triangle DEC
Since, the triangles are congruent, therefore
⇒AC = CD
⇒4y-6 = 2x+6 ...(1)
Also, BC = CE

Now, substituting the value of x in (1), we get,
⇒4y-6 = 2(3y+1)/4+(6)
⇒4y-6 = (6y+2 +24)/4
⇒16y-24 = 6y+2 +24
⇒10y = 50
⇒y = 5
Now putting the value of y in (2), we get
⇒(3(2)+1)/4 = x
⇒7/4 = x
⇒ x = 1.75

Use the given transformation to evaluate the integral.
u= x+y, v= -2x+y;
R\int \int5y dxdy where R is the parallelogram bounded by the lines y= -x+1, y=-x+4, y= 2x+2, y= 2x+5
a. 85/4
b. 65/4
c.85/2
d.65/2
After evaluating the integral answer is 85/4. thus, option A is the answer.
The given transformation is a change of variables from (x, y) to (u, v). To evaluate the integral using the transformation, we need to use the Jacobian determinant. The Jacobian determinant is the absolute value of the determinant of the matrix of partial derivatives of the transformation.
du/dx = 1, du/dy = 1
dv/dx = -2, dv/dy = 1
The determinant of the matrix of partial derivatives is det(J) = du/dx * dv/dy - du/dy * dv/dx = (1)(1) - (1)(-2) = 3
So the Jacobian determinant is |J| = |3| = 3.
The integral becomes:
R\int \int 5y dx dy = (1/3) R\int \int 5v du dv
where R is the region in the uv-plane that corresponds to the region in the xy-plane bounded by the lines y= -x+1, y=-x+4, y= 2x+2, y= 2x+5
The integral evaluates to (1/3) R\int \int 5v du dv = (1/3) * 85/2 = 85/6 = 85/4
Therefore the correct answer is 85/4

an even number. each card is worth a different number of points (this point value is written on the card). alice and bob then take turns removing either the leftmost or rightmost card from the row, until all the cards are gone. at that point, the player who has collected the most points is declared the winner.
The best strategy for Alice is to take the card with the highest point value. This will maximize her chances of winning, since she can then choose the last card from the remaining cards. Bob should take the card with the lowest point value, as this will minimize Alice's chances of winning.
Alice always takes the first turn. Bob can either take the leftmost card or the rightmost card. If Alice takes the leftmost card and Bob takes the rightmost card, then Alice will have the advantage of being able to make the last move. If Bob takes the leftmost card and Alice takes the rightmost card, then Bob will have the advantage of being able to make the last move.
The best strategy for Alice is to take the card with the highest point value. This will maximize her chances of winning, since she can then choose the last card from the remaining cards. Bob should take the card with the lowest point value, as this will minimize Alice's chances of winning.
Alice should also be aware of Bob's strategy and try to anticipate what card he will take. If Alice can guess correctly, she can adjust her strategy to ensure she takes the card with the highest point value. If she guesses incorrectly, she should still attempt to take the card with the highest point value.

The Surface area this of cylinder with radius 11cm and height 30 cm is 2833.71 cm².
What is a cylinder?Two parallel, identical bases connected by a curved surface form a 3D solid shape known as a cylinder. Similar to a disc in shape, these bases. The axis of the cylinder shape is a line drawn through the middle of, or connecting, two circular bases. Perpendicular distance is the measurement separating the two bases, and it is denoted by the letter "h," which stands for height. The distance between the two circular bases' centres and outer edges is known as the cylinder's radius and is denoted by the letter "r".
Surface area of cylinder = 2πr(r+ h)
= 2π11(11+ 30)
= 2833.71 cm²

A line which joins the midpoints of two sides of a triangle is Midsegment
A triangle's midsegment is a line formed by joining any two of the triangle's sides at their midpoints. All three sides of a triangle can be divided (split in half) in any triangle, whether it be right, isosceles, or equilateral. The midpoint of each side is the point that is equally spaced from either vertex.
Triangles can have three midsegments because they have three sides. Any two sides can be joined at their midpoints. Half the length of the base is represented by one midsegment (the third side not involved in the creation of the midsegment). That is the only intriguing aspect. It also:
Is consistently parallel to the triangle's third side; the base
