The dilation is an enlargement, then k > 1. If the dilation is a reduction, then 0 < k < 1.

The dilation constant, also known as the scale factor, represents the amount by which the original figure is enlarged or reduced in the dilation.

We can find the dilation constant by using the distance formula. Let the coordinates of point P be (x,y) and the coordinates of point A be (a,b). Let the coordinates of point B be (u,v), where u and v are unknown.

The distance from A to P is:

d(AP) = √[(x-a)² + (y-b)²]

The distance from A to B is:

d(AB) = √[(u-a)² + (v-b)²]

Since the dilation is centered at A and maps P onto B, we know that the ratio of the distances is the dilation constant:

d(AP)/d(AB) = k

Substituting the expressions for the distances and simplifying, we get:

√[(x-a)² + (y-b)²] / √[(u-a)² + (v-b)²] = k

Squaring both sides, we get:

[(x-a)² + (y-b)²] / [(u-a)² + (v-b)²] = k²

Since we know the coordinates of P and A, we can substitute these values into the equation and solve for k. Once we have k, we can use it to find the coordinates of B.

Note that if the dilation is an enlargement, then k > 1. If the dilation is a reduction, then 0 < k < 1.

Rectangle ABCD has diagonals AC and BD that converge at point O and

OA = 5x-7, OD = 4x-5.

A relation is any subset of a Cartesian product.

As an illustration, a subset of is referred to as a "binary connection from A to B," and more specifically, a "relation on A."

A binary relation from A to B is made up of these ordered pairs (a,b), where the first component is from A and the second component is from B.

Every item in a set X is connected to one item in a different set Y through a connection known as a function (possibly the same set).

A function is only represented by a graph, which is a collection of all ordered pairs (x, f (x)).

Every function, as you can see from these definitions, is a relation from X

Hence, Rectangle ABCD has diagonals AC and BD that converge at point O and

OA = 5x-7, OD = 4x-5.

Answer:

0.337 or about 33.7%

Step-by-step explanation:

The number of ways to choose 1 apple out of 9 is:

C(9, 1) = 9! / (1! * (9 - 1)!) = 9

The number of ways to choose 2 oranges out of 7 is:

C(7, 2) = 7! / (2! * (7 - 2)!) = 21

So the total number of ways to choose 1 apple and 2 oranges is:

9 * 21 = 189

The total number of ways to choose 3 fruits out of 16 is:

C(16, 3) = 560

Therefore, the probability of selecting 1 apple and 2 oranges is:

Therefore, Jamie can make 8 bracelets with 1.04 meters of wire.

Perimeter is a measure of the distance around the edge of a two-dimensional object, such as a polygon, a circle, or a rectangle. It is the total length of all the sides or edges that make up the shape. In simple terms, perimeter is the length of the boundary of a flat object, such as the circumference of a circle, or the sum of the lengths of the sides of a polygon. It is usually measured in units such as meters (m), centimeters (cm), feet (ft), or inches (in).

Here,

Jamie has 1.04 meters of wire, which is equivalent to 104 cm (since 1 meter = 100 cm).

Each bracelet requires 13 cm of wire, so the number of bracelets she can make is:

Number of bracelets = Total length of wire ÷ Length of wire per bracelet

Number of bracelets = 104 cm ÷ 13 cm/bracelet

Number of bracelets = 8

the probability that a randomly selected light bulb will last between 675 and 825 hours is 68.26%, or 0.6826.

Probability is a measure of the likelihood of an event occurring. It is a numerical value that ranges from 0 to 1, where 0 represents an impossible event and 1 represents a certain event. A probability of 0.5 (or 50%) means that the event is equally likely to occur as not occur.

To solve this problem, we can use the standard normal distribution with a mean of 0 and a standard deviation of 1, and then convert the given values to z-scores using the formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

For the lower value of x (675 hours), the z-score is:

z = (675 - 750) / 75 = -1

For the upper value of x (825 hours), the z-score is:

z = (825 - 750) / 75 = 1

We can then use a standard normal distribution table or calculator to find the probabilities associated with these z-scores:

P(z < -1) ≈ 0.1587

P(z < 1) ≈ 0.8413

The probability of a randomly selected light bulb lasting between 675 and 825 hours is then:

P(-1 < z < 1) = P(z < 1) - P(z < -1) ≈ 0.8413 - 0.1587 ≈ 0.6826

Therefore, the probability that a randomly selected light bulb will last between 675 and 825 hours is approximately 68.26%, or 0.6826 as a decimal.

Step-by-step explanation:

There are 210 ways that Janelle can choose 4 colors from 10 available colors for her art project.

Janelle needs to choose 4 colors out of 10 available colors for her art project. The order in which she chooses the colors does not matter. We can use the combination formula to determine the number of ways she can choose 4 colors from 10 available colors:

nCr = n! / r!(n - r)!

where n is the total number of colors available, r is the number of colors Janelle needs to choose, and ! denotes the factorial operation.

In this case, we have:

n = 10 (total number of colors available)

r = 4 (number of colors Janelle needs to choose)

Substituting these values into the formula, we get:

10C4 = 10! / 4!(10 - 4)!

= 10! / 4!6!

= (10 x 9 x 8 x 7) / (4 x 3 x 2 x 1)

= 210

Therefore, for her art assignment, Janelle can select 4 colors from a palette of 10 in 210 different ways.

After 4 months, Dalia will have the same number of gems as Grace, and after that, she will have more.

We need to find out when the number of gems Dalia has will exceed the number of gems Grace has.

Let's represent the number of months by "t".

After t months, Dalia will have 20t gems.

After t months, Grace will have 120 - 10t gems.

To find when Dalia will have more gems than Grace, we can set up an inequality:

20t > 120 - 10t

Simplifying the inequality, we get:

30t > 120

Dividing both sides by 30, we get:

t > 4

This means that Dalia will have more gems than Grace after 4 months.

To check our answer, we can substitute t = 4 into the expressions we found earlier:

After 4 months, Dalia will have 20t = 20(4) = 80 gems.

After 4 months, Grace will have 120 - 10t = 120 - 10(4) = 80 gems.

So, we can see that after 4 months, Dalia will have the same number of gems as Grace, and after that, she will have more.

Answer: First, we need to calculate the taxable income, which is the gross salary minus the tax-free threshold of $18,200:

Taxable income = Gross salary - Tax-free threshold

Taxable income = $18,700 - $18,200

Taxable income = $500

Since the taxable income falls within the range of $18,201-$37,000, we can use the tax rate of 19c for each $1 over $18,200 to calculate the amount of tax payable:

Tax on income = (Taxable income - $18,200) × 0.19

Tax on income = ($500 - $18,200) × 0.19

Tax on income = -$3,382 × 0.19

Tax on income = -$642.58 (rounded to the nearest cent)

However, the calculated tax is negative, which means that the person is entitled to a tax refund as they have paid more tax than they are required to. This can happen if they have been working for only part of the financial year, or if they have had tax withheld at a higher rate than necessary.

Step-by-step explanation:

The cοrrect answer is x > 0 and x < (- 3) where x is any number οn the number line.

A number line is a οne dimensiοnal graph (rather an endless straight line) οn which οne can represent every pοssible real number. Usually we have zerο serving as the center οf the number line, with the right hand side serving as the pοsitive part οf the real line and the left hand side as the negative part οf the real line.

A number line is endless which implies there is nο bοund tο a number line.

Any number οn the real line is denοted by a dark spοt οn the real line. Fοr example if οne needs tο denοte 3 οn the real line he/she has tο mark 3 with a spοt.

There are three kind οf intervals that can be represented οn the number line namely clοsed [ ] , οpen ( ) and semi-clοsed οr semi- οpen [ ) οr ( ]. Intervals οn number line are being shοwn by thickening that part οf the real line that are under cοnsideratiοn.

Fοr example: (4 , 5) is representing by thickening the number line between 4 and 5 with οpen ends , i.e. circles οn digit 4 and 5.

[4 , 6]   is represented by thickening the number line between 4 and 6 with clοsed οr black dοt ends.

Similarly semi οpen and semi clοsed intervals are represented by thickening the interval between thοse twο pοints with apprοpriate circles and dοts οn the endpοints.

Accοrding tο the given questiοn we need tο mark all described pοints that are pοsitive. Thus all pοints greater than zerο are tο be thickened (excluding zerο). This is dοne by having an οpen end οn pοint zerο and thickening the whοle οf the right hand side οr the pοsitive side οf the number line.

Similarly tο represent all described pοints οn the number line less than ( -3) (excluding ( - 3)) can be dοne by having an οpen end οn pοint ( - 3) and thickening the whοle οf the negative side tο the left οf ( - 3).

Thus to represent all the required points we can write them in a set A as:

A = { x : x > 0; x < ( - 3) }.

The first five terms of the sequence with a = 3 and r = -2 are: 3, -6, 12, -24, 48.

The general formula for a geometric sequence is given by:

an = a * r^(n-1)

where "a" is the first term, "r" is the common ratio, and "n" is the number of the term we want to find.

In this case, we have:

a = 3

r = -2

So the first term is 3, and the common ratio is -2. We can use the formula above to find the first five terms of the sequence:

a1 = 3

a2 = 3 * (-2)^(2-1) = -6

a3 = 3 * (-2)^(3-1) = 12

a4 = 3 * (-2)^(4-1) = -24
