Which graph represents the function of f(x) = 9x 2 -36/3x+6 Please help

Answers

The function is:

         (9x^2 - 36)
f(x) = ---------------------
                3x + 6

You can simplify that function to a linear function for all x for which 3x + 6 ≠ 0

=> x ≠ - 2.

So, for x ≠ - 2, you can do:

         (9x^2 - 36)
f(x) = --------------------- =
               3x + 6

          9(x^2 - 4)
f(x) = ---------------------
                3(x + 2)

         3(x + 2)(x - 2)
f(x) = --------------------- = 3(x - 2) = 3x - 6
                 (x + 2)

So, the graph is a right line that intercepts the y-axis at - 6 and the x-axis at x = 2, excluding x = -2 as the function is not defined for x = -2. That is the second graph of the second picture.

Final answer:

The given function is a quadratic equation, not a linear one, and so it would be represented by a parabolic curve on a graph, not a straight line.

Explanation:

The function you're asking about, f(x) = 9x² - 36/3x + 6, is a quadratic equation. Quadratic equations are represented by parabolas on the graph not a straight line. Parabolas usually have a shape like a U (or an upside down U, depending on the equation).

The equation you've given should result in a parabolic graph. The straight line equations and graphs you’re referring to, like y = 9+3x, would not represent your function. The line graph with a y-intercept of 9 and a slope of 3 is not a representation of your function.

Also, it's important to note that the equation you provided, f(x) = 9x² - 36/3x + 6, can be simplified to f(x) = 9x² - 12x + 6.

At what angle do the angle bisectors of two same side interior angles intersect in construction with two parallel lines and a transversal?

Answers

Same-side interior angles are a pair of angles on one side of a transversal line, and on the inside of the two parallel lines being intersected.

The sum of same-side interior angles is equal to 180 degrees.

A transversal line is a line that intersects other lines.

Parallel lines are lines that run alongside each other that never intersect.

An angle bisector is a line that divides an angle into two equal parts.

Given that the sum of same side interior angles is equal to 180 degrees, then the sum of the angle formed by the angle bisector is equal to 90 degrees.
Thus the angle bisectors intersect at an angle 90 degrees.

Therefore, the angle bisectors of two same side interior angles in construction with two parallel lines and a transversal intersect at angle 90 degrees.

Please help me I'm so confused and it's due at 7:30

Answers

Alright, so from what I understand, you need to create an equation with the solution x=5. One of the steps must include the distributive property. The distributive property essentially means that in x(y+z) with each letter representing a number, it turns into xy+xz. Since 5 is a prime number, we could work backwards. Just tossing out ideas, 5*4=20, so one step in your equation could be 20/4=x and dividing the 4. What's 4? 2 times 2, so we can make it 20/(2*2)=x. 1+1=2, so we can add that step. 20/((1+1)(2))=x, since 1+1=2 ,2*2=4, and 20/4=5. How do we extend 20? 20 equals 2*10, so we can make it (2*10)/((1+1)(2)). For a random thing to add, we can add 20-20 to the equation - it essentially does nothing but add a step since it equals 0, making our equation 20-20+(2*10)/((1+1)(2)).=x. In addition, since x is 5 and positive, we can square 5 (25) and find the square root of 25 to get 5, making our equation now sqrt(((20-20+(2*10)/((1+1)(2))))^2) =x. To decode it, we first cancel the sqrt (square root) and square. Now we know it is positive due to all square roots are positive. The equation is then ((20-20+(2*10)/((1+1)(2))) After that, we can multiply 2 and 10, making it 20-20+(20/((1+1)(2))). Next, we can use the distributive property to multiply 2*1 and 2*1, making it (20/(2+2))-20+20. Adding 2+2 and subtracting 20 from 20, we then get (20/4)=5=x. I challenge you to use something similar, but not the exact thing!

A first grader measures 1 meter high how much bigger is a first grader compared to the height of a book

Answers

To solve this problem, we would be needing the actual height or size of the book which is not given in the problem. However for the sake of calculation let us assume that the average height of a book is 8.5 inches.

Then the next step we have to do is to convert the height of the first grader from units of meter to units of inches. We know that:

1 meter = 39.37 inches

Therefore the height of the first grader is 39.37 inches.

Taking the ratio with the bigger number in the numerator (height of the 1st grader / height of the book):

ratio = 39.37 inches / 8.5 inches

ratio = 4.63

Therefore this means that the first grader is about 4.63 times taller than the book.

There are exactly four positive integers $n$ such that \[\frac{(n + 1)^2}{n + 23}\] is an integer. Compute the largest such $n$.

Answers

Final answer:

To find the largest positive integer $n$ such that $rac{(n + 1)^2}{n + 23}$ is an integer, we need to find the largest perfect square that is less than or equal to $n + 23$. The largest such $n$ is $41$.

Explanation:

To find the largest positive integer $n$ such that $rac{(n + 1)^2}{n + 23}$ is an integer, we can start by considering the numerator. The expression $(n + 1)^2$ is a perfect square, so it will always be divisible by $n + 23$ if $n + 23$ is also a perfect square. Therefore, we need to find the largest perfect square that is less than or equal to $n + 23$.

Let's consider some examples. If $n + 23 = 25$, then $n = 2$. If $n + 23 = 36$, then $n = 13$. If $n + 23 = 49$, then $n = 26$. If $n + 23 = 64$, then $n = 41$. Therefore, the largest value of $n$ such that $rac{(n + 1)^2}{n + 23}$ is an integer is $41$.

There are no positive integers $n$ that satisfy the given condition, and we cannot compute the largest such $n$.

To find the largest positive integer $n$ such that $\frac{(n + 1)^2}{n + 23}$ is an integer, we need to consider the factors of the numerator and denominator.

Let's expand the numerator, $(n + 1)^2$, using the binomial expansion formula:

$(n + 1)^2 = n^2 + 2n + 1$

Now, we divide this expression by $n + 23$ and express the result as an integer:

$\frac{n^2 + 2n + 1}{n + 23}$

We can use polynomial long division to divide $n^2 + 2n + 1$ by $n + 23$:

- (n - 21)
__________
n + 23 | n^2 + 2n + 1
- (n^2 + 23n)
_____________
-21n + 1
- (-21n - 483)
_____________
484

We obtain a remainder of 484. In order for the fraction to be an integer, the remainder must be 0. However, in this case, the remainder is not 0, which means that $\frac{(n + 1)^2}{n + 23}$ is not an integer for any positive integer $n$.

Therefore, there are no positive integers $n$ that satisfy the given condition, and we cannot compute the largest such $n$.

we know the length of the first picture, 6

[tex]\bf \cfrac{\textit{length of small}}{\textit{length of large}}\qquad 1.5:2\implies \cfrac{1.5}{2}=\cfrac{L}{6} [/tex]

solve for "L".

The new picture will have a length of 4.5 inches and a width of 3 inches.

There is asking about the size of a scaled-down photo in comparison to the original photo that has a length of 6 inches and a width of 4 inches. Given the ratio of the new picture to the size of the first picture is 1.5 to 2, we need to calculate the new dimensions.

The scale factor from the original to the new photo is 1.5 / 2, which simplifies to 0.75. Thus, we multiply the original dimensions by 0.75 to find the dimensions of the new picture:

Length of new picture = 6 inches * 0.75 = 4.5 inches

Width of new picture = 4 inches * 0.75 = 3 inches

5/8x - 3/8x = 6
2/8x = 6
x = 6 * 8/2
x = 48/2
x = 24

so the total length is 24
with the longest being : 5/8(24) = 15 <==
and the shortest being : 3/8(24) = 9

The length of the longest part is 15 units.

The length of the longest part in a segment divided into parts in the ratio of 5:3 with a difference of 6 units is 15 units.

The length of the longest part is 15 units.

Let the lengths of the two parts be 5x and 3x.Since the difference between them is 6, we can set up the equation 5x - 3x = 6.Solving for x gives x = 3, so the longest part is 5x = 5 * 3 = 15 units.

In four to five sentences, explain some of the factors that cause shifts in supply and demand and what the effects of these shifts are.

Answers

In the real world, businesses base all their projections to the law of demand and supply. The law of demand states that as the quantity of demand rises, the price of the product falls, and vice versa. On the other hand, as the quantity of supply rises, the price of the product also rises.

Let's take a situation for example. Company A's demand has decreased because a new product from Company has just been launched. Because of their advertisements in blockbuster movies, the product of Company B was bought by many people. Because of this, Company A decides to decrease their price so that people will opt to buy it. To do this, Company A has to reduce their supply. The qualitative graph is shown in the picture. S1&D1 and D2&D2 are supply and demand before and after Company B launched their product, respectively.

From the graph, we can say that from S1 and D1 to S2 and D2, the price decreases and the quantity of products also decreases.

Answer:

Sample Response: Shifts in supply and demand occur when the amount of goods available increases or decreases, or when the demand for a particular good increases or decreases. Shifts in supply can happen when consumers change their spending habits, when competitors produce similar goods, or when the availability of labor or resources changes. Shifts in demand occur when the price changes or when the number of people trying to buy the good changes. It can also happen when people's tastes change.

One of the acute angles of a right triangle is 50° and its hypotenuse is 7 inches. find the lengths of its legs to the nearest tenth of an inch.

Answers

Final answer:

To determine the lengths of the legs of a right triangle with a hypotenuse of 7 inches and an acute angle of 50°, we use the trigonometric functions cosine and sine. The adjacent leg (A) is approximately 4.5 inches and the opposite leg (B) is approximately 5.4 inches, both to the nearest tenth.

Explanation:

The student asked: "What are the lengths of the legs of a right triangle if one of the acute angles is 50° and the hypotenuse is 7 inches?"

To find the lengths of the legs of a right triangle, we can use trigonometry. The cosine of an angle in a right triangle is equal to the adjacent leg divided by the hypotenuse, and the sine of an angle is equal the opposite leg divided by the hypotenuse.

Since we know the hypotenuse (7 inches) and one acute angle (50°), we can find:

the length of the opposite leg (leg B) using sine (sin(50°) = leg B / 7 inches).

By solving these equations:

leg A = cos(50°) × 7 inches

leg B = sin(50°) × 7 inches

After calculating, we find:

leg A ≈ 4.5 inches (to the nearest tenth)

leg B ≈ 5.4 inches (to the nearest tenth)

Prove that for any x in the reals 5 divides x if and only if 5 divides x squared

Answers

I think we can do this by taking the contrapositive of the statement.

if the statement is true then the contrapositive is also true:-

If, for any real x, 5 does not divide x^2 then 5 does not divide x.

Any number that 5 will divide into must end in 0 or 5 so the above is evidently true.

So the original statement is also true.

Mike forgot to replace the cap on a bottle of room freshener. The room freshener began to evaporate at the rate of 15% per day. If the original amount of room freshener in the bottle was 40 grams, which of the following graphs best represents the amount of room freshener f(x) that would remain in the bottle after x days?

graph of function f of x equals 30 multiplied by 0.88 to the power of x

graph of exponential function going down from left to right in quadrant 1 through the point 0, 40 and approaching the x axis

graph of function f of x equals 50 multiplied by 0.82 to the power of x

graph of exponential function going down from left to right in quadrant 1 through the point 0, 4 and approaching the x axis

Answers

The decay rate is 100% - 15% = 75% = 0.75

The decay equation is f(x) = 40(0.75)ˣ
Where f(x) is the mass of air freshener left after x days of use

The graph of this function is given below

The correct description of the graph is statement 2:

graph of exponential function going down from left to right in quadrant 1 through the point 0, 40 and approaching the x axis

The person under is wrong but there chart is right. 100%-15%=85%

85%=.85

F(x)= 40(.85)^x

Write that in desmos graphing and you will get the chart.
