rewrite the rational expression x^3+5x^2+3x-10/x+4 in the form q(x) + r(x)/b(x)

Answers

Final answer:

To rewrite the rational expression x^3+5x^2+3x-10/x+4 in the form q(x) + r(x)/b(x), we can use polynomial division.

Explanation:

To rewrite the rational expression x^3+5x^2+3x-10/x+4 in the form q(x) + r(x)/b(x), we can use polynomial division. Here are the steps:

Divide x^3+5x^2+3x-10 by x+4 using polynomial division.Write the quotient obtained as q(x) and the remainder obtained as r(x).The denominator b(x) is the divisor, which is x+4.

Therefore, the rational expression x^3+5x^2+3x-10/x+4 can be rewritten as q(x) + r(x)/b(x), where:

q(x) is the quotient obtained from polynomial division.r(x) is the remainder obtained from polynomial division.b(x) is the divisor, which is x+4.

Which quantity is used to generate the error bars on a graph?
range
median
linear correlation
standard deviation

Answers

The error bars on a graph the error or uncertainty of the measure graphed. You can use diffferent statistics to represent this deviation or error, so your graph should state which is being used.

Of the four options listed the only one valid, a frequently used, is the standard deviation (you could use, two standard deviations, or an interval of confidence).

The answer is standard deviation.

What is the Area of the Sector?

In circles, a sector is said to be a part of a circle made of the arc of the circle together with its two radii. This means that it is a portion of the circle formed by a portion of the circumference (arc) and radii of the circle at both endpoints of the arc.

The formula for Area of a sector is given as;

A = θ/360 x πr²

where;

θ is the central angle of the sector

r is radius

Given data ,

Let the measure of the arc be represented as A = 235°

So , the difference of the measures of arc = 235 - 125°

Now , the measure of the external angle ∠ABC = ( 235 - 125 ) / 2

So , the external angle ∠ABC = 55°

Hence , the measure of angle ∠ABC = 55°

Find the area of the regular polygon. Give the answer to the nearest tenth.

dodecagon with a perimeter of 108 cm ...?

Answers

A regular dodecagon is a polygon with 12 equal sides.
Length of each side = 108/12 = 9 cm.

Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm

Area of each triangle = 9/2(16.79) = 75.57 cm^2

Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2

Each side is 9 cm long

a 12 sided regular polygon is composed of 24 right triangles with one side

half the length of a side = 4.5 cm

the other side is 4.5 / tan (360/24) = 4.5 / tan(15)

A = 24 (1/2) 4.5^2 / tan(15) = 906.9 cm^2

Maggie was thinking of a number. If she multiply the number by 3 ,subtracted by 8 ,added by 2 times the 5 original number . the result was 48. write an equation that the number satisfies. Then answer it.

Answers

i hope this helps you

number is ?

3.?-8+2.5.?=48

13.?=56

?=56/13

To solve the word problem, we set up and solved an algebraic equation. Maggie's original number is approximately 4.31 after converting the written problem into the equation 3x - 8 + 10x = 48 and solving for 'x'.

The goal is to translate the word problem into an algebraic equation and solve for the unknown number. If Maggie is thinking of a number, let's use 'x' to represent this unknown number. According to the problem, she multiplies the number by 3, subtracts 8, and then adds 2 times the original number 5 times. The result of these operations is 48. Here's how you set up the equation:

3x - 8 + 10x = 48

The next step is to combine like terms:

13x - 8 = 48

Now we add 8 to both sides of the equation:

13x = 56

The last step is to divide both sides by 13 to solve for x:

x = 56 / 13

x = 4.3077 or approximately 4.31 if rounded to two decimal places.

Therefore, Maggie's number is approximately 4.31.

What is the upper quartile median value?

Answers

(16,18,(23),25,26),34,(37,37,(40),41,46)
Q1 = 23
Q2 = 34
Q3 = 40 <== ur upper quartile median value

Answer:

The upper quartile median value is 40. Therefore second option is correct.

Step-by-step explanation:

Stem is first digit of a number and leaf is last digit of a number.

Stem 1 leaf 4 can be written as 14.

From the given table, the observations can be written as

[tex]16,18,23,25,26,34,37,37,40,41,46[/tex]

Total number of observations is 11, which is an odd number.

[tex]median=\frac{n+1}{2}\text{th term}[/tex]

[tex]median=\frac{11+1}{2}\text{th term}=6\text{th term}[/tex]

Therefore median is 34.

We have 5 terms before 34 and 5 terms after 34.

[tex]Q_1=\frac{n+1}{4}\text{th term}=3\text{th term}[/tex]

[tex]Q_1=23[/tex]

[tex]Q_3=\frac{3(n+1)}{4}\text{th term}=9\text{th term}[/tex]

[tex]Q_3=40[/tex]

Q₃ is also known as upper quartile median value. Therefore second option is correct.

Clark Kent walks 3 miles west and then 4 miles north. How far is it for Superman to fly in a straight line back to his starting point? (It makes a right triangle.)

Answers

You can use the Pythagorean theorem to solve this problem. 3 miles west would be 3 units to the left on a graph, and 4 miles north would be four units up on a graph. The last line would be the hypotenuse. Now, if you know about special right triangles, then it can be recognized that the triangle is a 3-4-5 triangle, and the hypotenuse is 5 units. Otherwise, the Pythagorean theorem can be used.

What is the average rate of change from x = 0 to x = 2?

− 4
− 8

5
Can you please help me?

Answers

The average rate of change from x = 0 to x = 2 for the parabola described in the question is -4. Hence the correct option is 1.

The average rate of change of a function between two points is calculated by subtracting the y-values (function outputs) and dividing by the difference in x-values (inputs). In this case, to find the average rate of change of the parabola from x = 0 to x = 2, we use the points (0, 3) and (2, -5).

The average rate of change = (y2 - y1) / (x2 - x1)

Substitute in the given points: ( -5 - 3 ) / ( 2 - 0 )

Simplify the expression: -8 / 2 = -4

is it possible for a line to pass through only one quadrant?
How about four quadrants? explain

Answers

Yes it is possible for a line to only start in one quadrant and never leave that quadrant and vice versa a line can start in one quadrant and pass into another quadrant but how will you know if you line will be in certain or multiple quadrants simple just look at your points given if you have the points (3,4) (4,5) you notice that your X's are positive and your Y's are positive there is only one quadrant were your X and Y are positive and that is quadrant 1 but lets say you have points (-4,5),(3,4) you see how one of the points have a negative X and a positive Y there is only one quadrant that has a negative X and a positive Y that is quadrant 2 and and for point (3,4) that is in quadrant 1 so your line will run through quadrant 2 and 1

yes it is possible for a line to only be in one quadrant and it is also possible for a line to be in multiple quadrants basically it can be any place on a plane

It is not possible for a line to pass through one quadrant. A line is a 2 dimensional shape and crosses through 2 quadrants, even if passing through the origin. If a line passes through the origin, it still only enters and exits 2 quadrants. there must be a curvature in order to cross 4 quadrants.

Which of the following shows the extraneous solution to the logarithmic equation below?
log3(18x^3)-log3(2x)=log3(144)

x=-16
x=-8
x=-4
x=-2

Answers

We can simplify this equation using logaritmic rules. logx-logb = log(x/b)

than our equation becomes.
log3((18x^3)/(2x)) = log3(144) or
log3(9x^2) = log3(144)

for x= -4 we get that left side is equal to right side
log3(9*(-4)^2) = log3(144)

but if you put that value of x=-4 in start you will get log3(18(-4)^3) which is log of negative value which is imposible. That is why x=-4 is extraneous solution.

The value that shows the extraneous solution to the logarithmic equation below is x = -4

Extraneous solutions to a system of equation

Given the logarithmic function expressed as:

log3(18x^3)-log3(2x)=log3(144)

This can also be written as:

log3(18x^3/2x) = log3(144)
log3 (9x^2) -= log3 (144)

Cancel out the log function to have:

9x^2 = 144

Divide both sides by 9

x^2 = 144/9
x^2 = 16

x = ±4

Hence the value that shows the extraneous solution to the logarithmic equation below is x = -4
