Answer: -3, 0

Step-by-step explanation:

If a line segment with endpoints (0,−3) and (0,−7) is rotated 90° clockwise, an endpoint of this rotated segment is (-3, 0) and (-7, 0).

In Mathematics and Geometry, a rotation is a type of transformation that moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

By applying either a rotation of 90° clockwise or a rotation of 270° counterclockwise to the coordinate of this line segment with endpoints (0,−3) and (0,−7), the coordinate of its image;

(x, y)                            →            (y, -x)

Point (0,−3)          →     Point (-3, 0)

Point (0, -7)          →     Point (-7, 0)

The value the function given by (A ∪ B) = {1, 2, 4, 5, 7, 9, 11, 12, 15, 16, 18} and (A ∩ B) = {7}.

We carry out specific operations in mathematics, such as addition, subtraction, multiplication, etc. Generally speaking, these operators accept two or more operands and output a result dependent on the operation carried out. Similar to this, in set theory, several operations are typically done on two or more sets to obtain a new set of elements depending on the operation. The number of elements supplied by the operation and processing the result of a collective set is represented by the union and overlap of sets. All of the components are taken into account in the outcome when there is a union, but only the ones that are shared when there is an intersection.

The union of the two sets depict all the terms present in both the sets.

Thus, the value of (A ∪ B) is:

(A ∪ B) = {1, 2, 4, 5, 7, 9, 11, 12, 15, 16, 18}

The intersection of the sets depict all the common terms present in the two sets thus the value of (A ∩ B) is:

(A ∩ B) = {7}

Hence, the value the function given by (A ∪ B) = {1, 2, 4, 5, 7, 9, 11, 12, 15, 16, 18} and (A ∩ B) = {7}.

The function g ( x ) in the graph has one x-intercept , y intercept and an oblique asymptote , a vertical asymptote

An asymptote is a line that a curve approaches but never touches. A line where the graph of a function converges is known as an asymptote. When graphing functions, asymptotes are typically not required

There are 3 types of asymptotes

Horizontal asymptote (HA) - It is a horizontal line and hence its equation is of the form y = k. Horizontal Asymptote is when the function f(x) is tending to zero

Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero

Slanting asymptote (Oblique asymptote) - It is a slanting line and hence its equation is of the form y = mx + b

Given data ,

Let the function be represented as g ( x )

Now , the value of g ( x ) is

g ( x ) = ( -4x² + 36 ) / ( x + 3 )

On simplifying , we get

g ( x ) = -4 ( x² - 9 ) / ( x + 3 )

On further simplification , we get

g ( x ) = -4 ( x + 3 ) ( x - 3 ) / ( x + 3 )

g ( x ) = -4 ( x - 3 )

g ( x ) = -4x + 12

Now , the function has a vertical asymptote at ( 0 , 12 )

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

x + 32 + 4x + 20 + 4x + 20 = 180

9x + 72 = 180  ( subtract 72 from both sides )

9x = 108 ( divide both sides by 9 )

x = 12

then the 3 angles are

x + 32 = 12 + 32 = 44°

4x + 20 = 4(12) + 20 = 48 + 20 = 68°

4x + 20 = 68°

an obtuse angle is greater than 90°

none of the 3 angles in the triangle are obtuse

Answer:

No

Step-by-step explanation:

All angles of a triangle add up to 180°.

4x + 20 + 4x + 20 + x + 32 = 180

1. Simplify

9x + 72 = 180

2. Subtract 72 from both sides.

9x = 108

3. Divide both sides by 9.

x = 12

Replace x by 12 in each angle.

-  12 + 32 = 44°

-  4(12) + 20 = 68°

-  4(12) + 20 = 68°

All of the angles are less than 90°, so they aren't obtuse.

Step-by-step explanation:

To determine the percentage increase between 2017 and 2018, we need to calculate the difference between the two years and then divide by the 2017 value and multiply by 100. So, the calculation would be:

(9960,000 - 9640,000) / 9640,000 * 100 = 3.125%

So, the number of households increased by 3.125% from 2017 to 2018.

To find the number of households in 2019, we need to find the increase from 2018 to 2019. We can do this by multiplying the number of households in 2018 by the percentage increase, and then add that to the 2018 value. So, the calculation would be:

9960,000 * (3.125 / 100) + 9960,000 = 10,298,800

Therefore, there would be approximately 10,298,800 households in 2019, rounded to the nearest ten thousand.

Answer:

$10576.38

Step-by-step explanation:

To calculate the investment amount required to produce $23711 at an interest rate of 3.6% compounded monthly for 15 years, you can use the formula for compound interest:

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

where:

A is the amount of money you have after "t" years,

P is the initial investment amount (what you want to find),

r is the interest rate as a decimal,

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

t is the number of years the investment will be compounded for.

In this case,

r = 0.036

n = 12 (because the interest is compounded monthly)

t = 15

So, we can plug in the values into the formula and solve for P:

A = P * (1 + 0.036/12)^(12 * 15)

$23711 = P * (1.003)^(180)

$23711 = P * 2.2375

Dividing both sides by 2.2375:

P = $23711 / 2.2375

P = $10576.38

So, to produce $23711 at an interest rate of 3.6% compounded monthly for 15 years, you would need to invest $10576.38. Rounded to the nearest dollar, this amount is $10576.

Answer:

Step-by-step explanation:

Let's use the formula rate = cost/length to find the cost of one inch of wire. We know that 23 inches of wire cost 92 cents, so the rate of one inch of wire can be found by dividing 92 cents by 23 inches:

rate = cost/length = 92 cents/23 inches = 4 cents/inch

Now that we have found the rate of one inch of wire, we can use it to find the cost of 34 inches of wire. We simply multiply the rate by the length:

cost = rate * length = 4 cents/inch * 34 inches = 136 cents

So, 34 inches of wire will cost 136 cents.

Step-by-step explanation:

the trick is to find the "norm" rate, which is the rate for one unit.

from there we can get the rate for any number of units just by multiplying.

so,

23 in for 92 cents.

that means the rate is

23/92 = 23/(23×4) = 1/4

so, by dividing numerator and denominator by 23 (in this case it has an integer result also for the denominator) we get the price for 1 inch of wire : 4 cents.

so, 34 inches then have the length/price ratio (we multiply numerator and denominator by 34)

1/4 × 34/34 = 34/136

that means 34 inches cost 136 cents (= $1.36).

Right angles are angles whose measure is 90 degrees.

In the figure, AE, BF, DG, and HC intersect at point H, and FHG is a right angle.

(a) ∠AHB and ∠AHG are vertical angles.

Vertical angles are angles which are formed on the opposite sides of two intersecting lines.

∠AHB and ∠AHG are not formed on the opposite sides, but are adjacent to each other.

So the statement is false.

(b) ∠EHF and ∠DHE are adjacent angles.

∠EHF and ∠DHE are two angles which are adjacent to each other. So they are adjacent angles.

So the statement is true.

(c) The measure of ∠FHG is equal to the measure ∠DHF.

We know that DG is a straight line.

∠FHG and ∠DHF are linear pair of angles.

So, ∠FHG + ∠DHF = 180°

Given that ∠FHG is right angle.

90° + ∠DHF = 180°

∠DHF = 180° - 90°

∠DHF = 90°

So the statement is true.

The statistical measurement known as the Z-score describes the connection between a value and the mean of a set of values and the required z-score to the three decimal places is −2.714.

The relationship between a value and a set of values' mean is described by the statistical measurement known as the Z-score.

Standard deviations from the mean are used to measure Z-score.

A Z-score of zero means the data point's score is the same as the mean score.

Your observed value is 2.5 standard deviations from the mean if your Z-score is 2.5, and so on.

Your value is more closely aligned with the mean the closer your Z-score is to zero.

Your value is further from the mean the farther your Z-score is from zero.

So, let's say Rosetta wins the game on Thursday with 110 points.

When x=110, the z-score is -2.714.

The average is 148.

You can see from this z-score that x=110 is 2.714 standard deviations away from the mean.

This formula can be used to determine the z-score:

z = x−μ/σ

Answer:

Marianna will have $19,700 in her annuity after 6 years.

Step-by-step explanation:

To find the amount of money in the annuity after 6 years, we need to calculate the compound interest earned over that time period.

First, let's find the interest rate per quarter: 8% annual interest divided by 4 quarters per year = 2% interest per quarter.

Next, we'll calculate the number of quarters that the money is invested: 6 years x 4 quarters per year = 24 quarters.

Now we can use the formula for compound interest to find the total amount of money in the annuity after 6 years:

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

Where:

A = final amount

P = initial investment ($10,000 in this case)

r = interest rate per quarter (2% or 0.02)

n = number of times the interest is compounded in a year (4)

t = number of years invested (6)

Plugging in the values:

A = $10,000 * (1 + 0.02)^(24)

A = $10,000 * 1.96634438

A = $19,663.44

Rounding to the nearest hundred dollars: $19,700

So, Marianna will have $19,700 in her annuity after 6 years.

(b)

31250 ft²

Step-by-step explanation:

(a)

In total, the farmer used 875ft worth of fencing.

In terms of x, the total fencing used is: 2x + x + x + x + 2x = 7x

This means 7x=875ft. Dividing both sides by 7, we find x=125ft

The dimensions of the rectangular enclosure in terms of x are "x and 2x". Subbing in 125ft for x, these dimensions become "125ft and 2(125ft)" or "125ft and 250ft".

(b)

Since we know the enclosure is 125ft long and 250ft wide, and since the area of a rectangle is its length times its width, the are of the enclosure is:

125ft * 250ft = 31250 ft²

The set of numbers for which the statement that the square root of a number is greater than the square of the number is true, is equals to (0,1). So, right choice is option (a).

In mathematics, when we multiplying the number by itself, the result is called square of number. This is usually equivalent to raising a number to the power of 2. For example, square of 4 is 4² = 16. The square root of a number is that factor of a number which when multiplied by itself the original number. Square root of number is usually equivalent to raising a number to the power of 1/2. It is represented using the symbol '√'. Now, we have to check the options and determine where square root of a number is greater than the square of the number.

a) (0, 1), if we plug f(x) = √x , x∈(0,1) and g(x) = x² , x∈(0,1) on calculator then we get, the value of f(x) is greater than g(x), i.e, x = 1/2 , f(1/2) = 0.70 and g(1/2) = 0.25.

b) [0, 1], if we plug x = 0 then f(0) = 0 , g(0) = 0

that is f(x) is greater than and equal to g(x). But we have to consider only greater than not equal.

c) [1,∞), closed bracket again represents equality which is not consider. So, statement is false for it.

d) (1,∞), here number inbetween 1 and infinite but not for all reals it is true that square root of a number is greater than the square of the number, for example x = 2 , f(2) =1.414, g( 2) = 4 implies f(x)< g(x) for x = 2. So, the statement is false for it.
