The two coordinate values are simply swapped in the reflection over the line y=x: A'' = (4, 1) (4, 1)

The x-coordinate and y-coordinate of a point change positions when it is reflected across the line y = x.

The x- and y-coordinates shift positions and are negated when a point is mirrored across the line y = -x.

In light of this, the reflection of the point (x, y) across the line y = x is (y, x).

The first reflection's location across the vertical line x=-3 ensures that the y-coordinate is constant.

The point (-3, 4) on the line of reflection will become the halfway point between A and A' thanks to the x-coordinate of A':

(-3, 4) = (A +A')/2

2(-3, 4) (-3, 4)

-A = A' = (-6-(-7), 8 -4) = (1, 4) (1, 4)

The width of a rectangular field is  20 meters

Let l represents the length of a rectangular field, w represents the width of a rectangular field and d represents the diagonal of a rectangular field

We know that all the four angles of rectangle are right angle.

A diagonal of rectangle divides a rectangle into two equal right triangles.

Consider a right triangle with hypotenuse = diagonal (d) and the sides of the right triangle are nothing but the length and width of recangle.

Using Pythagoras theorem,

d² = l² + w²

52² = 48² + w²

w² = 52² - 48²

w² = 400

w =  ±20

But the width can not be -20

So, w = 20

Thus , the width is 20 meters

Answer:

  (x, y) = (4, -3)

Step-by-step explanation:

You want to solve this system of equations using substitution.

The substitution method requires that you find an expression for one of the variables that you can use to replace that variable in the other equation.

Here, we choose to use the second equation to write an expression for y. This makes the resulting coefficients be decimal values.

  5y = 9 -6x . . . . subtract 6x

  y = 1.8 -1.2x . . . . divide by 5

Substituting this for y in the first equation gives ...

  4x -3(1.8 -1.2x) = 25

  7.6x -5.4 = 25 . . . . . . . simplify

  7.6x = 30.4 . . . . . . . . add 5.4

  x = 4 . . . . . . . . . . divide by 7.6

  y = 1.8 -1.2(4) = 1.8 -4.8

  y = -3

The solution is (x, y) = (4, -3).

Additional comment

We could have used the first equation to write an expression for x. That would also make the coefficients be terminating decimal values. Using the first equation to write an expression for y leaves coefficients that are multiples of 1/3, not nice decimals. Similarly, solving the second equation for x would result in coefficients that are multiples of 1/6, also not nice decimals.

These "not nice" values can be used to get the same result. It just depends on what kind of arithmetic you want to do: fractions or decimals.

This set of coefficients would generally indicate that some other method would be more desirable to use: graphing, or matrix methods, for example. The attachment shows a matrix method.

The length of side x in the given triangle is 4√3 units.

In the given triangle with a base length of 8√3 and angles at the vertices of 60°, 90°, and 30°, we can use trigonometry to find the length of side x.

Since we know that one angle is 90°, we can use the 30-60-90 triangle ratios to determine the other sides. The ratios for a 30-60-90 triangle are as follows:

Opposite side (x) / hypotenuse (8√3) = sin 30° = 1/2

Adjacent side (y) / hypotenuse (8√3) = cos 30° = √3/2

So, using these ratios, we can calculate the length of the opposite side (x):

x = (8√3) (1/2) = 4√3

Therefore, the length of side x in the given triangle is 4√3 units.

Answer:

the interest rate required in order for Josiah to end up with $5,400, assuming the interest is compounded daily, is 10.3%

Step-by-step explanation:

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^nt

Where:

A = the amount of money in the account after the interest has been added

P = the initial investment (principal) of $4,800

r = the annual interest rate (expressed as a decimal)

n = the number of times the interest is compounded per year

t = the number of years the money is left in the account

We know that A = $5,400 and t = 6 years, so we can substitute these values into the formula:

5400 = 4800(1 + r/n)^(6n)

To find the interest rate, we need to solve for r.

we know that the interest is compounded daily, so we will use n = 365

5400 = 4800(1 + r/365)^(6*365)

To find the interest rate, we need to solve for r, we can use a calculator to find the value of r.

r ≈ 0.103 or 10.3% to the nearest tenth of a percent

So, the interest rate required in order for Josiah to end up with $5,400, assuming the interest is compounded daily, is 10.3%

Answer: Given a line represented by the equation 3x + y = 9, the slope of the line is -3/1. Since we know that the slope of the line perpendicular to this line is the negative reciprocal of the original line's slope, we can find the slope of the perpendicular line by taking -1/-3 = 1/3.

To find the equation of the perpendicular line that passes through the point (1,-2), we can use the point-slope form of the line equation, which is: y - y1 = m(x - x1) where m is the slope of the line and (x1,y1) is a point on the line.

Therefore, the equation of the perpendicular line that passes through the point (1,-2) is:

y - (-2) = (1/3)(x - 1)

y + 2 = (1/3)x + (1/3)

y = (1/3)x - (2/3)

So the final equation of the perpendicular line is y = (1/3)x - (2/3)

Answer:

18 is 90% of 20.

Solution:

We already have our first value 18 and the second value 90. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 1

[tex]18=90*y[/tex]

STEP 2

[tex]18=\frac{90}{100} *y[/tex]

Multiplying both sides by 100 and dividing both sides of the equation by 90 we will arrive at:

STEP 3

[tex]y=18*\frac{100}{90}[/tex]

STEP 4

[tex]y=18*100[/tex] ÷ [tex]90[/tex]

STEP 5

[tex]y=20[/tex]

Finally, we have found the value of Y which is 20 and that is our answer.

You can easily calculate 18 is 90 percent of what number by using any regular calculator, simply enter 18 × 100 ÷ 90 and you will get your answer which is 20.

Hope this helps! If you mark Brainliest, TYSM! :D

What is a percentage?

A percentage is a ratio, or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

We can convert 90% into a fraction, making it 90/100 or 9/10.

Now that we have that fraction, we can multiply that by 20.

9/10 × 20 = 18

Therefore, 18 is 90% of 20.

The value that the probability of correctly classifying a type an insect equals the probability of correctly classifying a type b insect is 4.5 millimeters.

To find the value that the probability of correctly classifying a type A insect equals the probability of correctly classifying a type B insect, we need to find the point where the probability density functions of the two types of insects intersect.

For type A insects, the probability density function is given as -

f(x) = [tex](1/2)e^{-{x-3}^{2/2}}[/tex]

For type B insects, the probability density function is given as-

f(x) = [tex](1/4)e^{-{x-5}^{2/2}}[/tex]

We can set these two probability density functions equal to each other and solve for x as follows -

[tex](1/2)e^{-{x-3}^{2/2}}[/tex] =  [tex](1/4)e^{-{x-5}^{2/2}}[/tex]

Solving for x, we get:

x = 4.5

So the value that the probability of correctly classifying a type A insect equals the probability of correctly classifying a type B insect and is 4.5 millimeters. This means that if the length of the insect is 4.5 millimeters or less, it will be classified as type A, and if it is greater than 4.5 millimeters, it will be classified as type B.

Answer:

Step-by-step explanation:

1. Find the slope-intercept form of the equation

So to first solve this equation you need to find the slope of the line to find the slope you do [tex]\frac{rise}{run}[/tex] which means you count the number of boxes the line moves up or down which is 2 so that is the "rise" part of our equation. To find the run you find how much the equation moves left or right which is one. So the slope would be [tex]\frac{2}{1} x[/tex] or [tex]2x\\[/tex]. To find the y-intercept you look at where the line hits the y-axis which is at -2. So now you have your equation in a slope-intercept form which is [tex]g(x)=2x-2[/tex]

2. Find g(-1)

So... The slope-intercept form of the equation is [tex]g(x)=2x-2[/tex] that you replace the x in the g(x) with -1 so now you replace the x in the slope-intercept equation with -1. Then simplify!

[tex]g(-1)=2(-1)-2[/tex]

[tex]g(-1)= -2-2[/tex]

[tex]g(-1)=-4[/tex]

To find the base of a trapezoid, you need to know the length of at least one of the bases and the height (or the length of the median). Since you know that PO is 13 (top base) and QR is 18 (median), you can use the following formula to find the length of the bottom base (MN):

Height x ((base1 + base2) / 2) = Area

Where the height is the length of the median (QR) and base1 and base2 are the lengths of the two bases (PO and MN).

So, in this case, you would have:

QR x ((PO + MN) / 2) = Area

18 x ((13 + MN) / 2) = Area

Solving for MN:

MN = (2 * Area) / QR - PO

So you can fill the area of trapezoid and substitute the values in the above formula.

===============================================

Explanation:

x = length of MN

A trapezoid has exactly one pair of parallel sides. The median is parallel to those mentioned sides. Think of it like the median to a highway.

A useful property is the median is the average of the parallel sides. We add up the outer sides, then divide by 2, and it gets us the median.

So,

QR = (MN + PO)/2

18 = (x + 13)/2

18*2 = x+13

36 = x+13

x = 36-13

x = 23

Approximately 99.7% falls within three standard deviations.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

The empirical rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations, and approximately 99.7% falls within three standard deviations.

Since the mean score is 50 and the standard deviation is 10, this means that approximately 68% of the students scored between 40 and 60, approximately 95% scored between 30 and 70, and approximately 99.7% scored between 20 and 80. Therefore, approximately 32% of students scored above 60.

First, we assume that the two horizontal lines are parallel, that will mean that the measures of angle 4 and 7 are equal, beacause both of them are on the same quadrant.

Also, notice that angle 7 and 141° should add up to 180° (a plane angle) thus, we will get:

m∠7 + 141° = 180°

We can use the power rule to find the derivative of f(x) = x^n + x^(n-1). The power rule states that the derivative of x^n is nx^(n-1).

So, the derivative of x^n is nx^(n-1)

And the derivative of x^(n-1) is (n-1)x^(n-2)

So the derivative of f(x) = x^n + x^(n-1) is:

f'(x) = nx^(n-1) + (n-1)x^(n-2)

Now, if we combine the exponents we have :

f'(x) = nx^n-1 + nx^n-2

And we can factor out x^n-2 from the second term, we have:

f'(x) = nx^n-1 + (n-1)x^n-2*x^2

Now, we can simplify the expression by canceling the x^n-2 factor.

f'(x) = nx^n-1 + (n-1)x

And finally, by simplifying the exponent and factoring the constants, we have:

f'(x) = (nx + n - 1) / x^(2-n)

So the derivative of f(x) = x^n + x^(n-1) is f'(x) = (nx + n - 1) / x^(2-n)
