If you graph a linear characteristic you may get a immediately line. There also are nonlinear functions. If you graph the coordinates of a nonlinear characteristic you may now no longer get a immediately line.

One of the very best ways (however now no longer the handiest way) to differentiate among a linear and a nonlinear characteristic is to have a take a observe the graph of the characteristic.

A linear equation is an equation with  variables whose graph is a line. The graph of the linear equation is a hard and fast of factors withinside the coordinate aircraft that every one are answers to the equation. If all variables constitute actual numbers you can graph the equation via way of means of plotting sufficient factors to understand a sample after which join the factors to encompass all factors.

The coordinates after the reflection of the points will be(7, -3).

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse.

Given that, (-7,3) is reflected across the x-axis, and then the y-axis.

When reflected across x-axis, it will be (-7, -3)

And again when reflected across y-axis it will be (7, -3)

Hence, The coordinates after the reflection of the points will be(7, -3)

Answer:

$3.78

Step-by-step explanation:

To find the new price of the speaker after the sale, you can use the following formula:

New price = (1 + discount percentage) * (original price - discount amount)

In this case, the discount percentage is 40%, or 0.4, and the discount amount is 40% of the original price, or 0.4 * $4.50 = $1.80. Plugging these values into the formula, we get:

New price = (1 + 0.4) * ($4.50 - $1.80)

= 1.4 * $2.70

= $3.78

So the new price of the speaker after the sale and the subsequent price increase is $3.78.

The required age of Liza's sister is given as 6 years.

Given that,
Liza is one year older than her sister. In four years she will be 3 times as old as she is now. How old is her sister now is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Let the age of Liza be x and of her sister be y,
According to the question,
x = y + 1
After 4 years,
4 + (y + 1) = 3(y + 1)

A reflexive, symmetric, transitive binary connection is an equivalence relation. One such illustration of an equivalence relation is the relation of equipollence between line segments in geometry.

demonstrate the equivalence of R. We must demonstrate

1). reflexive

x +2x = 3x and 3/ 3x  = 3/x +2x

(x,x) ∈ R

R is reflexive

2). symmetric

let (x,y )  ∈ R

x + 2y = 3a for some a ∈ R

consider y +2x = y + 2(3a - 2y)

6a - 3y = 3(2a - y) = 3k

3/y +2x

so (y,x)  ∈ R

R is symmetric

3). transitive

(x,y) and (y,x) ∈ R

3/x+2y and 3/y+2x

x+2y =3a and y +2x = 2b for some a,b

consider x+2z = 3a - 2y + 2 (3b-y/2)

3a +3b -3y

3(a+b-y)

3/x+2z

(x,z) ∈ R

R is tansitive

so R is equivalence relation

b).S = (-7, -6, -2,0,1,4,5,7)

cl (x) = { y∈ z , x∈ y }

cl (x) = {y∈ z , x +2y = 3a}

cl (x) =  {y∈ z , y = 3a - x /2}

cl (-7) = {y∈ z , y = 3a +7  /2}

x≈33.36

Step-by-step explanation:

The marks on the lines mean they are the same lenth, that means the other two angles are both 29 degrees. Because triangle angles add up to 360, we can add the two 29 degree angles and subtract them from 360 to get the angle of the equation. From here we can solve to find x.

$2256000 is the top rate paid the previous year.

percentage, a relative value indicating hundredth parts of any quantity.

Given that top rate paid one year for a 30 - second TV ad during the Super Bowl was 6% greater than the previous year's top rate.

If the new top rate paid was $2.4 million then we need to find the top rate paid the previous year.

Convert 6% to the decimal by dividing with 100 is 0.06

0.06×2400000

144000

Now subtract 144000 from 2.4 million.

2400000-144000

We are given that Josh is 3 years older than 4 times Kim's age. We can express this as 4k + 3, where k represents Kim's age. We are told that the sum of their ages is less than 43, so we can write this as an inequality: 4k + 3 < 43. To find the oldest age Kim could be, we can solve this inequality for k. To do this, we subtract 3 from both sides, giving us 4k < 40. Finally, we divide both sides by 4, giving us k < 10. Therefore, the oldest age Kim could be is 10.

Probability can be used to make predictions or decisions in a variety of situations, such as in gambling, finance, and science. In these situations, probabilities can be calculated based on statistical data or by using mathematical models.

To determine the probability of each of the five smallest y values, we can use the probability of each possible outcome and the number of ways that outcome can occur.

P(y = 1) = probability that the first component is defect-free = 0.8

P(y = 2) = probability that the first component is defective and the second component is defect-free = (1 - 0.8) * 0.8 = 0.16

P(y = 3) = probability that the first two components are defective and the third component is defect-free = (1 - 0.8) * (1 - 0.8) * 0.8 = 0.032

P(y = 4) = probability that the first three components are defective and the fourth component is defect-free = (1 - 0.8) * (1 - 0.8) * (1 - 0.8) * 0.8 = 0.0064

P(y = 5) = probability that the first four components are defective and the fifth component is defect-free = (1 - 0.8) * (1 - 0.8) * (1 - 0.8) * (1 - 0.8) * 0.8 = 0.00128

We can see that the probability of each y value is simply the probability of the previous y value multiplied by (1 - 0.8) = 0.2. This means that the probability distribution of y is given by the formula P(y) = 0.2^(y - 1) * 0.8.

What is direct proportion?

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value.

It is symbolised by the proportional sign ∝.

For instance, if x and y are two quantities or variables that are intimately linked to one another, we can say x & y. The ratio of x and y becomes equal to a constant when the proportionality sign is removed, for example, x/y = C, where C is a constant.

the volume of a cone if the height is 10 cm and the diameter is 6 cm is 94.25 cubic centimeters

We know that a right circular cone has a circular base with the apex above the center of the base.

For a right circular cone, with radius r and height h

The formula for the volume of a right circular cone is,

V = 1/3 * π * r² * h

We need to find the the volume of a right circular cone with a circumference.

We know that circumference C = 2πr

From circumference we find the radius of circular base.

Then using the formula for the volume of a right circular cone, we find the volume.

The volume of a circular cone:

If the height(h) of the circular cone is given then,

V = 1/3 * π * r² * h

If the slant height(l) of the circular cone is given then,

V = 1/3 * π * r² * √(l² - r²)

Now we need to find the the volume of a cone if the height is 10 cm and the diameter is 6 cm

From diameter, the radius of the circular base of the cone would be,

r = 6/2

r = 3 cm

also, h = 10 cm

So, V = 1/3 * π * 3² * 10

V = 94.25 cu.cm.

Standard error is defined as the measures of the preciseness of an estimate of a population mean. It can be calculated by dividing the sample standard deviation by the square root of the sample size.

where SE = standard error

SD = sample standard deviation
