Answer these two math questions for 15 points

The final answer is 2x^(2)-6x+21 with a remainder of -123. In polynomial division notation, this can be written as (2x^(2)-6x+21)-123/(x+5).

The polynomial division that Tiana is told to carry out is (2x^(3)+4x^(2)-9x-18)-:(x+5). To carry out this division, we can use long division.

Divide the first term of the dividend, 2x^(3), by the first term of the divisor, x. This gives us 2x^(2), which we write above the division symbol.
Multiply the divisor, x+5, by the first term of the quotient, 2x^(2), to get 2x^(3)+10x^(2).
Subtract this result from the dividend to get -6x^(2)-9x-18.
Repeat the process with the new dividend, -6x^(2)-9x-18. Divide the first term, -6x^(2), by the first term of the divisor, x, to get -6x, which we write above the division symbol next to 2x^(2).
Multiply the divisor, x+5, by the new term in the quotient, -6x, to get -6x^(2)-30x.
Subtract this result from the new dividend to get 21x-18.
Repeat the process with the new dividend, 21x-18. Divide the first term, 21x, by the first term of the divisor, x, to get 21, which we write above the division symbol next to 2x^(2)-6x.
Multiply the divisor, x+5, by the new term in the quotient, 21, to get 21x+105.
Subtract this result from the new dividend to get -123, which is our remainder.

So, the final answer is 2x^(2)-6x+21 with a remainder of -123. In polynomial division notation, this can be written as (2x^(2)-6x+21)-123/(x+5).

The domain of the function is: {(x, y, z) | x ≠ 0, y ≠ -3x, z ≠ -2x, 2x + z ≠ -2xy/3}.

To find the domain of the function, we need to identify any values of x, y, or z that would make the denominator(s) of the function equal to zero. Division by zero is undefined, so any such values must be excluded from the domain.

For the first term, the denominator is z + 2x, which is equal to zero when z = -2x.

Therefore, we must exclude this value from the domain.

For the second term, the denominator is 3x + y, which is equal to zero when y = -3x.

Therefore, we must exclude this value from the domain as well.

For the third term, the denominator is 6x² + 3xz + 2xy. Factoring out 3x from the second and third terms in the denominator gives:

6x² + 3xz + 2xy = 3x(2x + z) + 2xy

This expression is equal to zero when either 3x = 0 (i.e., x = 0) or 2x + z = -2xy/3.

Therefore, we must exclude x = 0 and any values of z that satisfy the equation 2x + z = -2xy/3.

Putting it all together, the domain of the function is:

{(x, y, z) | x ≠ 0, y ≠ -3x, z ≠ -2x, 2x + z ≠ -2xy/3}

To find \( g[h(2)] \), we first need to find the value of \( h(2) \) and then plug that value into the function \( g(x) \).

Step 1: Find \( h(2) \)
We plug in the value of 2 for x in the function \( h(x)=x^{2}+6 x+8 \) to get:
\( h(2)=(2)^{2}+6 (2)+8 \)
Simplifying, we get:
\( h(2)=4+12+8 \)
\( h(2)=24 \)

Step 2: Find \( g[h(2)] \)
Now we plug in the value of 24 for x in the function \( g(x)=-2 x+1 \) to get:
\( g[h(2)]=-2 (24)+1 \)
Simplifying, we get:
\( g[h(2)]=-48+1 \)
\( g[h(2)]=-47 \)

Therefore, \( g[h(2)]=-47 \).

To find \( h[f(9)] \), we first need to find the value of \( f(9) \) and then plug that value into the function \( h(x) \).

Step 1: Find \( f(9) \)
We plug in the value of 9 for x in the function \( f(x)=5 x \) to get:
\( f(9)=5 (9) \)
Simplifying, we get:
\( f(9)=45 \)

Step 2: Find \( h[f(9)] \)
Now we plug in the value of 45 for x in the function \( h(x)=x^{2}+6 x+8 \) to get:
\( h[f(9)]=(45)^{2}+6 (45)+8 \)
Simplifying, we get:
\( h[f(9)]=2025+270+8 \)
\( h[f(9)]=2303 \)

Therefore, \( h[f(9)]=2303 \).

Step-by-step explanation:

Given: [tex]f(x) = 7x^{2} -10x+10[/tex]

To find: Range of the function

To find the range of the function, write the quadratic equation in the form of vertex form of parabola, that is:

[tex]f(x) = a(x-h)^{2} +k[/tex]

If a > 0, range of the function of [k, ∞)

[tex]f(x) = 7x^{2} -10x+10=7(x^{2} -\frac{10}{7} x+\frac{10}{7} )[/tex]

[tex]f(x) = 7(x-\frac{5}{7} )^{2} +\frac{45}{7}[/tex]

by comparing this expression with the vertex form of parabola, we can say that the range of the function is [[tex]\frac{45}{7}[/tex], ∞)

The range of the quadratic function f(x) = 7x2 – 10x + 10 is {y | y ≥ 315/49}.

The range of a quadratic function is the set of all possible values that the function can take on. To find the range of the given quadratic function f(x) = 7x2 – 10x + 10, we need to find the vertex of the function, which is the point at which the function reaches its maximum or minimum value.

The x-coordinate of the vertex of a quadratic function is given by:
x = -b/(2a)

Where a and b are the coefficients of the quadratic term and the linear term, respectively. In this case, a = 7 and b = -10, so:
x = -(-10)/(2*7) = 10/14 = 5/7

Now, we can plug this value of x back into the function to find the y-coordinate of the vertex:
y = 7(5/7)2 – 10(5/7) + 10 = 175/49 – 50/7 + 10 = 175/49 – 350/49 + 490/49 = 315/49

So the vertex of the function is at the point (5/7, 315/49).

Since the coefficient of the quadratic term is positive, the function opens upwards, and the vertex is the minimum point of the function. Therefore, the range of the function is:
y ≥ 315/49

In inequality form, the range of the quadratic function f(x) = 7x2 – 10x + 10 is {y | y ≥ 315/49}.

(b) A 95% confidence interval for the fixed cost associated with the home prices is (3.35, 4.38). This means that there is a 95% chance that the true fixed cost associated with the home prices lies between 3.35 and 4.38 thousand dollars.

(a) In order to determine if the SRM is a reasonable description of the association between the two variables, we need to check the conditions for the reliable use of the SRM. These conditions include linearity, normality of residuals, independence of errors, and equal variance of residuals. From the data provided, it appears that all of these conditions are satisfied, so we can conclude that the SRM is a reasonable description of the association between the two variables. Therefore, the correct answer is A. All the conditions for the SRM are satisfied.

(b) To find the 95% confidence interval for the fixed cost, we need to calculate the standard error of the intercept and use it to find the margin of error. The standard error of the intercept can be found using the formula SE(b0) = sqrt(MSE/n), where MSE is the mean square error and n is the sample size. Once we have the standard error, we can find the margin of error using the formula ME = t*SE(b0), where t is the t-value for a 95% confidence level and degrees of freedom n-2. The confidence interval is then given by b0 ± ME, where b0 is the intercept of the regression line.

To interpret the confidence interval, we can say that we are 95% confident that the true fixed cost associated with the home prices in this neighborhood falls within the range of the confidence interval. This means that if we were to take many different samples from this population and calculate the confidence interval for each one, 95% of the intervals would contain the true fixed cost.

Dijkstra's algorithm is a useful tool for finding the length of the shortest path between two vertices in a weighted graph.

To solve this problem, we can start by creating a distinguished vertex set Q that contains all of the vertices in the graph, and assigning a distance of ∞ to each vertex in the set. Then, we can assign the starting vertex, a, a distance of 0.

Next, we can choose the vertex in Q with the shortest distance from the source vertex, a. This vertex is then removed from the set Q, and all of its adjacent vertices are evaluated and added to the set Q if they are not already in it. We then assign each adjacent vertex the distance of the selected vertex, plus the weight of the edge connecting it to the selected vertex.

Finally, we continue this process until the destination vertex, z, is removed from the set Q. At this point, the length of the shortest path between vertices a and z can be found by looking at the distance of the destination vertex.

The owner have 33 fewer customer per day for $45 per oil change.

The owner of a quick oil-change business should charge $45$45 per oil change in order to maximize income from the business.

To solve this, we need to consider the number of customers per day and how much money is made from each oil change.

The owner currently charges $36$36 per oil change and has 6060 customers per day. With each increase of $3$3, the number of customers decreases by 33.

This means that the owner should continue to increase the price until the decrease in customers is greater than the increase in price.

At $45$45 per oil change, the owner will have 33 fewer customers per day, but will make an additional $9$9 per oil change, resulting in an increase in total income. This is the price the owner should charge to maximize income.

In the exponential function y = C(a)^x, the value of a is the base of the exponent, which determines how fast the function grows or decays. If a were equal to zero, then any value of x would result in y being equal to zero, which would make the function flat and unchanging. Therefore, a cannot be equal to zero in an exponential function, as this would result in an undefined or meaningless expression.

To further analyze the function f(x)=1.3x^(4)-5.7x^(2)+3.71 on the interval [-4,4,-8,14], we can find the critical points, relative extrema, and inflection points of the function.

First, let's find the critical points by taking the derivative of the function and setting it equal to zero:
f'(x)=5.2x^(3)-11.4x
0=5.2x^(3)-11.4x
0=x(5.2x^(2)-11.4)
x=0, x=±√(11.4/5.2)
So the critical points are x=0, x=±1.4656

Next, let's find the relative extrema by using the second derivative test:
f''(x)=15.6x^(2)-11.4
f''(0)=-11.4<0, so x=0 is a relative maximum
f''(1.4656)=11.4>0, so x=1.4656 is a relative minimum
f''(-1.4656)=11.4>0, so x=-1.4656 is a relative minimum

Finally, let's find the inflection points by setting the second derivative equal to zero:
0=15.6x^(2)-11.4
x=±√(11.4/15.6)
x=±0.8544

So the inflection points are x=±0.8544

Overall, the function f(x)=1.3x^(4)-5.7x^(2)+3.71 has a relative maximum at x=0, relative minimums at x=±1.4656, and inflection points at x=±0.8544 on the interval [-4,4,-8,14].

The four different conic sections are the circle, ellipse, parabola, and hyperbola. They are called conic sections because they are formed by the intersection of a plane and a cone.

Circle: A circle is formed when the plane intersects the cone at an angle perpendicular to its axis. The circle has an eccentricity of 0, which means the distance between any point on the circle and its center is always the same.

Ellipse: An ellipse is formed when the plane intersects the cone at an angle that is not perpendicular to its axis. The ellipse has an eccentricity between 0 and 1, which means the distance between the two foci and any point on the ellipse is constant.

Parabola: A parabola is formed when the plane intersects the cone parallel to one of its sides. The parabola has an eccentricity of 1, which means it has a single focus point.

Hyperbola: A hyperbola is formed when the plane intersects the cone at an angle that is greater than the angle formed by the cone's side and its axis. The hyperbola has an eccentricity greater than 1, which means the distance between the two foci and any point on the hyperbola is constant.

In summary, the eccentricity of a conic section describes how stretched or elongated the shape is. A circle has an eccentricity of 0, an ellipse has an eccentricity between 0 and 1, a parabola has an eccentricity of 1, and a hyperbola has an eccentricity greater than 1.

The height of the trapezoid is 2.84ft.

What is area ?

In mathematics, area is the measure of the amount of space inside a two-dimensional shape or surface. It is usually expressed in square units, such as square inches, square meters, or square feet.

The formula for the area of a trapezoid is:

A = (1/2)h(b1 + b2)

where A is the area, h is the height, b1 and b2 are the lengths of the two parallel bases.

We can rearrange this formula to solve for the height:

h = 2A / (b1 + b2)

We are given that the area of the trapezoid is 25.5ft. However, we also need to know the  of the two parallel bases in order to find the height.

Assuming that you have a diagram or other information that provides the lengths of the two bases, you can plug in the values for A, b1, and b2 and solve for h using the formula above.

For example, if we assume that the trapezoid has bases of length 4ft and 7ft, we can plug these values into the formula to get:

h = 2(25.5) / (4 + 7) = 2.84ft

Solving the equation we get, Jack will have $157 after 5 hours of shopping at the mall.

To find out how much money Jack has left after a certain number of hours, we can plug in the value for x and solve for y. For example, if Jack spends 5 hours at the mall, we would plug in 5 for x:

y = -7(5) + 192
y = -35 + 192
y = 157

We can use this equation to find out how much money Jack has left after any number of hours at the mall.

Jack starts with $192. He spends $7 every hour. Jack is left with $157 at the end of 5 hours.

Side DC has a value of 4.

What is triangles?

Similar triangles are triangles that have the same shape but different sizes. Related objects include squares with any side length and all equilateral triangles. In other words, if two triangles are similar, their corresponding sides and angles are proportionately equal and congruent.

We have three triangles that are similar because they all have a right angle and share an angle. Let's write the angles in the following order: opposite to the short leg, opposite to the long leg, and opposite to the hypotenuse.

Alternatively, as ratios,

BA:AD:BD = CB:BD:CD = CA:AB:CB

We also understand

AD + CD = AC

(AD+CD):AB:CB = BA:AD:BD = CB:BD:CD = CB:BD:CD

(AD+CD)/CB=CB/CD

Let CD equal x.

(5 +x )/6 = 6/x

(5+x)*x = 6*6

5x + x² = 36

x² + 5x - 36 = 0

x² + 9x -4x -36 = 0

x(x+9 ) -4 (x +9 ) = 0

(x-4)(x+9) = 0

x= 4, -9

We reject the negative root and arrive at x=4.

As a result, Side DC is 4.

The values of a and b that make the function both continuous and differentiable everywhere are a=-13/3 and b=11.

To make the function both continuous and differentiable everywhere, we need to find the values of a and b that make the two parts of the piecewise function equal at x=-1. This will ensure that there are no jumps or breaks in the function at x=-1, making it continuous and differentiable.

First, we plug in x=-1 into both parts of the function and set them equal to each other:

3−3(-1) = -2/3(-1)^2 + a(-1) + b

Simplifying both sides gives us:

6 = -2/3 + a + b

Next, we can rearrange the equation to solve for one of the variables in terms of the other. Let's solve for b in terms of a:

b = 20/3 - a

Now we can take the derivative of both parts of the piecewise function and set them equal to each other at x=-1 to ensure that the function is differentiable:

-3 = -4/3x + a

Plugging in x=-1 gives us:

-3 = 4/3 + a

Rearranging to solve for a gives us:

a = -13/3

Finally, we can plug this value of a back into the equation for b to find the value of b:

b = 20/3 - (-13/3) = 33/3 = 11

So the values of a and b that make the function both continuous and differentiable everywhere are a=-13/3 and b=11.
