Answer:

4 m^3 - 38 m^2 + 57 m - 72 = (4 m^2 - 6 m + 9)(m - 8) + 0

Step-by-step explanation:

Compute (4 m^3 - 38 m^2 + 57 m - 72) ÷ (m - 8) using polynomial long division:

m - 8 | 4 m^3 | - | 38 m^2 | + | 57 m | - | 72

To eliminate the leading term of the numerator, 4 m^3, multiply m - 8 by 4 m^2 to get 4 m^3 - 32 m^2. Write 4 m^2 on top of the division bracket and subtract 4 m^3 - 32 m^2 from 4 m^3 - 38 m^2 + 57 m - 72 to get -6 m^2 + 57 m - 72:

| | | 4 m^2 | | | |

m - 8 | 4 m^3 | - | 38 m^2 | + | 57 m | - | 72

| -(4 m^3 | - | 32 m^2) | | | |

| | | -6 m^2 | + | 57 m | - | 72

To eliminate the leading term of the remainder of the previous step, -6 m^2, multiply m - 8 by -6 m to get -6 m^2 + 48 m. Write -6 m on top of the division bracket and subtract -6 m^2 + 48 m from -6 m^2 + 57 m - 72 to get 9 m - 72:

| | | 4 m^2 | - | 6 m | |

m - 8 | 4 m^3 | - | 38 m^2 | + | 57 m | - | 72

| -(4 m^3 | - | 32 m^2) | | | |

| | | -6 m^2 | + | 57 m | - | 72

| | | -(-6 m^2 | + | 48 m) | |

| | | | | 9 m | - | 72

To eliminate the leading term of the remainder of the previous step, 9 m, multiply m - 8 by 9 to get 9 m - 72. Write 9 on top of the division bracket and subtract 9 m - 72 from 9 m - 72 to get 0:

| | | 4 m^2 | - | 6 m | + | 9

m - 8 | 4 m^3 | - | 38 m^2 | + | 57 m | - | 72

| -(4 m^3 | - | 32 m^2) | | | |

| | | -6 m^2 | + | 57 m | - | 72

| | | -(-6 m^2 | + | 48 m) | |

| | | | | 9 m | - | 72

| | | | | -(9 m | - | 72)

| | | | | | | 0

The quotient of (4 m^3 - 38 m^2 + 57 m - 72)/(m - 8) is the sum of the terms on top of the division bracket. Since the final subtraction step resulted in zero, m - 8 exactly divides 4 m^3 - 38 m^2 + 57 m - 72, and there is no remainder.

| | | 4 m^2 | - | 6 m | + | 9 | (quotient)

m - 8 | 4 m^3 | - | 38 m^2 | + | 57 m | - | 72 |

| -(4 m^3 | - | 32 m^2) | | | | |

| | | -6 m^2 | + | 57 m | - | 72 |

| | | -(-6 m^2 | + | 48 m) | | |

| | | | | 9 m | - | 72 |

| | | | | -(9 m | - | 72) |

| | | | | | | 0 | (remainder) invisible comma

(4 m^3 - 38 m^2 + 57 m - 72)/(m - 8) = (4 m^2 - 6 m + 9) + 0

Write the result in quotient and remainder form:

Answer: 4 m^3 - 38 m^2 + 57 m - 72 = (4 m^2 - 6 m + 9)(m - 8) + 0

3) Juakali used Kingo's computer to type a report document which had 123 pages, and
each page occupied by 70 lines. 36 of 70 lines had 14 words while the remaining lines
had 18 words each. He wanted to take the document with him, and he had only a flash
disk with 256 KB as free space. Can he successfully save the document on the device?
Why?

Answers

To determine whether Juakali can successfully save the document on the flash disk, you can calculate the total number of words in the document and compare it to the amount of free space on the flash disk.

First, calculate the total number of lines in the document by multiplying the number of pages by the number of lines per page:

Total number of lines = 123 pages * 70 lines/page

= 8610 lines

Next, calculate the number of lines with 14 words by multiplying the total number of lines by the proportion of lines with 14 words:

Number of lines with 14 words = 8610 lines * 36/70

= 4380 lines

Calculate the total number of words in the lines with 14 words by multiplying the number of lines by the number of words per line:

Total number of words in lines with 14 words = 4380 lines * 14 words/line

= 61320 words

Calculate the number of lines with 18 words by subtracting the number of lines with 14 words from the total number of lines:

Number of lines with 18 words = 8610 lines - 4380 lines

= 4230 lines

Calculate the total number of words in the lines with 18 words by multiplying the number of lines by the number of words per line:

Total number of words in lines with 18 words = 4230 lines * 18 words/line

= 76140 words

Finally, add the total number of words in the lines with 14 words and the total number of words in the lines with 18 words to find the total number of words in the document:

Total number of words = 61320 words + 76140 words

= 137,460 words

To determine whether Juakali can successfully save the document on the flash disk, you can compare the total number of words in the document to the amount of free space on the flash disk. Since the flash disk has 256 KB of free space and there are 137,460 words in the document, Juakali will not be able to save the document on the flash disk. This is because the document is larger than the amount of free space available on the flash disk.

It is important to note that the capacity of a storage device is usually measured in bytes, and 1 KB is equal to 1024 bytes.

Answers

The new perimeter will be 2 times larger then the old perimeter, if both dimensions of rectangle are doubled.

What is perimeter ?

The length of a shape's outline is its perimeter. You must add the lengths of all four sides of a rectangle or square to determine its perimeter. In this instance, x represents the rectangle's length and y its width.

The figure's length is essentially revealed by the perimeter. Assume that the perimeter of a square with equal sides will be four times that square's sides. The perimeter of a circle, which is determined by its radius, is known as its circumference.

The new dimensions  of rectangle = 4mm and 9mm

The original dimension = 2mm and 4.5 mm

Perimeter of rectangle = P=2(l+w) = 2 (4.5 +2 ) = 13 mm

Perimeter of rectangle after doubled dimension = 2 (9 + 4) = 26

So, the new perimeter will be 2 times larger then the old perimeter

A 224​-inch is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece.

Answers

A 60-inch piece is the shorter one. 180 inches long is the longer piece.

Step-by-step explanation:

Let's use the variables L and S to symbolise the longer and shorter pieces of pipe, respectively.Since the pipe will be the sum of L and S, we can create the following equation:

L + S = 240

Additionally, we are aware that the longer piece is tri-times the shorter piece, which means:

L = 3 S

Replace the first equation with the second equation:

L + S = 240 ( 3 S ) + S = 240 \s 4 S = 240 \s S = 60

A 60-inch piece is the shorter one.Replace the following with the lengthier piece's length:

L = 3 S L = 3 ( 60 )

L =180

180 inches long is the lengthier piece.Let's give the shorter piece a value.The length is "X." The other piece is three times as big, or three times.When you add them up, you get 4X.

Answers

95% confidence that machine calibrated properly is (48.536, 51.424).

We have given that,

n = 25

mean of x = 49.98 mm

S = 0.14 mm

μ = 50.00 mm

and CI = 95%

from t-table we know that,

t at 95% and n - 1 = 25 - 1 = 24 is 2.064

Therefore 95% of CI means that

(x - 2.064 × S√n, x + 2.064 × S√n)

(49.98 - 2.064 × 0.14√25, 49.98 + 2.064 × 0.14√25)

(49.98 - 2.064 × 0.7, 49.98 + 2.064 × 0.7)

(49.98 - 1.444 , 49.98 + 1.444)

(48.536, 51.424)

Therefore 95% confidence that machine calibrated properly is

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

A + B + C = 119

Country B won 9 more than Country C so:

B = C + 9

Also, Country A won 39 more than the other two combined so:

A = B + C + 39

  = (C + 9) + C + 39

  = 2C + 48

Now we substitute into the equation:

A + B + C = 129

(2C + 48) + (C + 9) + C = 129

4C + 57 = 129

4C = 72

C = 18

A substance grows exponentially, and its weight doubles every 3 hours. Suppose it weighs 2 pounds at noon. After how many hours will it weigh 9 pounds? (Do not simplify result)

Answers

The substance will weigh 9 pounds after  4.5123 hours.

Here it is given that every 3 hours the weight of the substance doubles.

At 12 noon it weighed 2 pounds. Hence we will consider the initial weight to be 2.

Let the weight after x hours be w(x)

Here it doubles in 3 hours, hence the growth rate is 100%

Since the growth rate is given, the equation for the growth rate will be

w(x) = w₀.eˣ

where x = no. of 3-hour spans.

Here

w₀ = 2

and w(x) is given 9

Hence,

2eˣ = 9

or, e²ˣ = 9/2

Taking log on both sides we get

loge²ˣ = ln(9/2)

or, 2xloge = ln(9/2)

Since loge = 1 we get

2x = log(9/2)

or, x = 1.5041

Hence they will become 9 pounds after

3 X 1.5041 hours

We are given an isosceles triangle because two sides are marked congruent, and therefore, the base angles opposite those sides are congruent. First we need to calculate the angles of the triangle using the Isosceles Triangle Theorem.

We are given a 110° angle with a ray that forms a straight line. Straight lines measure 180° by definition. So, we can calculate the vertex angle in the triangle by creating this equation:

110+x=180

110 degrees plus x creates a 180 degree line. Now, solve for x:

x=70

We have our first angle in the triangle, and we know a triangle must sum up to 180°. We also know the triangle is isosceles, and so the two base angles are congruent. We can create another equation to find all angles in the triangle:

70+2x=180

Remember, we have one angle and because the two base angles are congruent, we can denote them with the same variable and multiply by 2 because the angles will add to each other twice. Solve for x:

2x=110

x=55

So, we now have all there angles and can solve for “x.” Like we did before, a straight line forms one of the rays of the angle. So, we can create the equation:

55+x=180

55° plus x° sums up to 180. Now, solve for “x:”

b) The price of a house increases exponentially over time. A house presently costs $400,000, and it future
value can be modeled by the equation: A = 400,000 (1.04)*, where A is the value of the home after x years.
i) What percent is the house's value going up each year?
ii) What is the value of the home in 15 years?
ii) Assuming the trend continues, when will the value of the home double?
+4

Answers

Answer:  The percent that the house's value is going up each year is given by the factor 1.04 - 1, which is 0.04. This represents a 4% increase in the value of the house each year.

ii) To find the value of the home in 15 years, you can substitute x = 15 into the equation to get:

A = 400,000 (1.04)^15

= 400,000 (1.7589)

= 700,356

Therefore, the value of the home in 15 years is $700,356.

iii) To find when the value of the home will double, you can set the value of A equal to 2*400,000 and solve for x:

2*400,000 = 400,000 (1.04)^x

2 = (1.04)^x

x = log(2)/log(1.04)

= 10.67

Therefore, it will take approximately 10.67 years for the value of the home to double, assuming the trend continues.

Suppose Colleen works two jobs. At job A, Colleen’s monthly earnings can be described by the distribution N(2100, 200) and at job B, her monthly earnings can be described by the distribution N(550, 70). Assuming that her earnings are independent,


1) What is the mean and standard deviation of the TOTAL amount of money she earns in a month? (this will use knowledge from prior units)

2) What is the probability that she earns more than $2750 in a given month?

Answers

1) The mean and the standard deviation of the total amount of money that she earns in a month are of:

Mean: 2650.Standard deviation: 211.9.

2) The probability that she earns more than $2750 in a given month is of: 0.3192 = 31.92%.

How to obtain probabilities using the normal distribution?

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.

When two variables are added, the mean is given by the sum of the means, hence:

[tex]\mu = 2100 + 550 = 2650[/tex]

The standard deviation is given by the square root of the sum of the variances, hence:

[tex]\sigma = \sqrt{200^2 + 70^2} = 211.9[/tex]

The probability that she earns more than $2750 in a given month is  one subtracted by the p-value of Z = 2750, hence:

Z = (2750 - 2650)/211.9

Z = 0.47

Z = 0.47 has a p-value of 0.6808.

1 - 0.6808 = 0.3192 = 31.92%.

If a polynomial function has integer coefficients, then every rational zero of the function has the form p/q, where p is a factor of the ? and q is a factor of the ?

Answers

If a polynomial function has integer coefficients, the every rational zero of the function has the form p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

The rational zero theorem says that if a polynomial has integer coefficients then any rational zeros must be of the form p/q where p is the factor of the constant term and q is the factor pf the leading coefficients.

The rational zero theorem is used to determine the rational roots of a polynomial function.

Rational Zero Theorem statement:-

The rational zero theorem states that each rational zero(s) of a polynomial wit integer coefficients
