at least one x-intercept
at least one y-intercept
Dan oblique asymptote
O a vertical asymptote
the domain of x
The function g ( x ) in the graph has one x-intercept , y intercept and an oblique asymptote , a vertical asymptote
What are Asymptotes?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 )
The function has a horizontal asymptote at ( 3 , 0 )
Hence , the function is solved

In the figure, AE, BF, DG, and HC intersect at point H, and FHG is a right angle.
Somebody help, I don't get this!
The statements are (a) False, (b) True and (c) False
What are Right Angles?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.
Hence the statements (a), (b) and (c) are false, true and true respectively.

What would you need to invest to produce $23711 if your interest rate is 3.6% compounded monthly for 15 years? Round your answer to the nearest dollar.
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.

What is a nonlinear?A nonlinear system is one in mathematics and science where the change in the output is not proportional to the change in the input. Since the majority of systems are fundamentally nonlinear, engineers, biologists, physicists, mathematicians, and many other scientists are interested in nonlinear problems. A nonlinear equation is one in which the highest degree of any term is two or more. For instance, 3x2. + 2x + 1 = 0, 3x + 4y = 5, is an example of a nonlinear equation since equation 1 has the greatest degree of 2, while equation 2 involves variables x and y.

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.
What is the z-score?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
=110−148/14
=−38/14
≈−2.714
Therefore, the required z-score to the three decimal places is −2.714.

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

What is meant by combination?
Combinations are ways to choose things from a collection where the order of the choices is irrelevant. It is described as an arrangement of items where the order in which they are chosen is irrelevant.
Given,
Number of engineers in the faculty = 20
Number of engineers required to form a committee = 20
1) Number of ways when either engr. Marzo or engr. William is only present.
Excluding Marzo and William, we have 18 engineers.
So we can select 6 engineers from these 18 = 18C6 = [tex]\frac{18!}{6!12!}[/tex] = 18564
Number of ways we can select only one from Marzo and William = 2C1 = 2
So the total number of combinations for forming a committee = 18564 + 2 = 18566
2) Engr. Cara and Eng. Danny are present.
Engr. Hillary is not considered.
So we have to select 5 members from the rest of the 15 people
Number of combinations are = 15C5 = 3003
3) Engineers Gilliam, Fernando and Ophelia are selected.
Now we have to select the rest of the 4 members from the remaining 15 people
Number of combinations = 15C4 = 1365

Marianna finds an annuity that pays 8% annual interest, compounded quarterly. She invests in this annuity and contributes $10,000 each quarter for 6 years. How much money will be in her annuity after 6 years? Enter your answer rounded to the nearest hundred dollars.
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.

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:

The square root of a number is greater than the square of the number. For what set of numbers is this true?.
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.

Does the triangle contain an obtuse angle?.
Explain your reasoning.
Please help me urgent need
Answer:
No
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.

Demonstrating the properties of rotations, if a line segment with endpoints (0,−3) and (0,−7) is rotated 90° clockwise, what is an endpoint of this rotated segment?
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).
What is a rotation?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)

If the percentage increase between 2017 of 9,640,000 and 2018 of 9,960,000 continued in 2018 and 2019 , how many households would be there be in 2019 ? Round to the nearest ten thousand
Answer:
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.
23 inches of wire cost 92 cents at the same rate, how much (in cents) will 34 inches of wire cost?
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).
