At which root does the graph of f (x) = (x - 5)3 (x + 2)2 touch the xaxis

Answers

Answer 1

ANSWER

x=-2

EXPLANATION

The given polynomial function is:

[tex]f(x) = {(x - 5)}^{3} {(x + 2)}^{2} [/tex]

The polynomial has two factors, one with an odd multiplicity which is

[tex] {(x - 5)}^{3} [/tex]

and the other with an even multiplicity which is

[tex] {(x + 2)}^{2} [/tex]

The graph does not cross the x-axis at where the multiplicity is even.

Therefore the graph touches the x-axis at

[tex]x = - 2[/tex]

We got this by solving

[tex]{(x + 2)}^{2} = 0[/tex]

Thomas forgot that his uncle traveled with the military and has lived in 15 different places since high school. Let B represent the set of the number of places where all ten of his family members, including his uncle, have lived after high school.

Answers

The difference between set A and set B is the inclusion of data from Thomas's uncle in B. Notice that his uncle has lived in many more places than the rest of the people in the data set. Because of this, the average (mean) of the data set will be greater in B because having an outlier from the rest of the data will shift the mean towards that outlier.

Answer: The mean of B is greater than the mean of A.

Answers

the angles are supplementary meaning they equal 180 degrees so 100-x=180

x=80

ANSWER

[tex]m \angle ACE = 80 \degree[/tex]

EXPLANATION

Recall that adjacent angles on a straight line will add up to 180°

From the diagram, m<ACD and m<ACE are adjacent angles on a straight line because they have a common vertex at C.

We sum the two angles and equate them to 180°

[tex] m \angle \: ACD + m \angle ACE = 180 \degree[/tex]

From the diagram

[tex]m\angle ACD= 100 \degree[/tex]

We substitute the known angle to obtain:

[tex]100 \degree + m \angle ACE = 180 \degree[/tex]

[tex]m \angle ACE = 180 \degree - 100 \degree[/tex]

[tex] \therefore \: m \angle ACE = 80 \degree[/tex]

ABC has been translated 5 units to the right, as shown in the diagram. What is the length of A1B1?

Answers

Answer:

10

Step-by-step explanation:

If the triangle is translated ANY amount of units ANYWHERE, the length of each segment AND the angles will ALL be the same.

Why?

Because if you translate something, you are only moving it somewhere else. You aren't stretching the shape or making any modifications. You are simply moving it, and that will only change the coordinates the points will be at.

The length of A1B1 is 10.

What is translation?

Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.

If 0.89=1-1/k^2, how do I find K?

Answers

Step-by-step explanation:

0.89 = 1 - 1/(k²)

Start by subtracting 1 from both sides:

0.89 - 1 = -1/(k²)

-0.11 = -1/(k²)

Multiply both sides by -1:

0.11 = 1/(k²)

Multiply both sides by k²:

0.11 k² = 1

Divide both sides by 0.11:

k² = 1 / 0.11

Take the square root:

k = √(1 / 0.11)

Answer:

+/- 3.015 to the nearest thousandth.

Step-by-step explanation:

0.89 = 1 - 1 / k^2

Multiply through by k^2

0.89k^2 = k^2 - 1

k^2 - 0.89k^2 = 1

0.11 k^2 = 1

k^2 = 1/0.11 = 9.091

k = +/- √0.091

= +/-3.015.

In a simple random sample, individuals all have an equal chance of being selected, ensuring unbiased and representative data. Thus, option a. is correct.

In a simple random sample, individuals all have an equal chance of being selected, and all samples have an equal chance of being selected. This method ensures that each member of the population is equally likely to be chosen, resulting in unbiased and representative data.

Other sampling methods like cluster sampling and stratified sampling do involve randomness but in different ways. For instance, cluster sampling involves selecting entire clusters, such as departments or geographical areas, at random and including all members from those clusters in the sample.

In contrast, stratified sampling involves dividing the population into strata based on characteristics and then randomly sampling from each stratum.

Thus, option a. simple random sample is correct.

gallon that the company uses to reimburse
employees?
• The company has 126 employees who
commute..
• The average employee traveled 12,250 miles
to and from work over the course of the year.
The average gas mileage reported by all
employees was 22.5 miles per gallon.
• The company paid out a total of $96,040.00
in gas reimbursements.
A) $0.44
B) $0.71
C) $1.40
D) $1.60

Answers

inal answer:

To calculate the reimbursement rate per gallon, multiply the total miles traveled by all employees by the average gas mileage and divide the total reimbursement amount by the total gallons used, resulting in a rate of $1.40 per gallon.

Explanation:

To find the rate in dollars per gallon that the company uses to reimburse employees, we need to calculate the total gallons of gas consumed and then divide the total amount paid out by the total gallons used.

The average employee traveled 12,250 miles, and the average gas mileage was 22.5 miles per gallon:

Total miles for all employees: 126 employees × 12,250 miles/employee = 1,543,500 miles.

Total gallons consumed: 1,543,500 miles ÷ 22.5 miles/gallon = 68,600 gallons.

Rate of reimbursement per gallon: $96,040.00 ÷ 68,600 gallons ≈ $1.40 per gallon.

Therefore, the reimbursement rate is $1.40 per gallon.

Final answer:

The reimbursement rate in dollars per gallon is calculated by determining the total gallons of gas used by all employees and then dividing the total reimbursement amount by this figure. The computation shows a reimbursement rate of $1.40 per gallon.

Explanation:

To determine the rate in dollars per gallon that the company uses to reimburse employees, we need to calculate the total gallons of gas used by the average employee and then find out how much the company paid per gallon.

Calculate the total gallons used by the average employee. The average miles traveled is 12,250 miles, and the average gas mileage is 22.5 miles per gallon.Total Gallons = Total Miles ÷ Miles per Gallon = 12,250 miles ÷ 22.5 MPG = 544.44 gallons (rounded to two decimal places).Calculate the total gallons used by all employees by multiplying the average gallons per employee by the number of employees.Total Gallons for All Employees = 544.44 gallons × 126 employees = 68,599.44 gallons.Now, calculate the reimbursement rate by dividing the total amount paid out by the total gallons used.Reimbursement Rate = Total Reimbursement ÷ Total Gallons = $96,040.00 ÷ 68,599.44 gallons = $1.40 per gallon.

Thus, the correct answer is C) $1.40 per gallon.

Solve the formula for converting temperature from degrees Celsius to degrees Fahrenheit for C
F= 9/5C+32

Answers

Answer:

5/9(F-32) = C

Step-by-step explanation:

F= 9/5C+32

Subtract 32 from each side

F-32= 9/5C+32-32

F-32 = 9/5 C

Multiply each side by 5/9 to isolate C

5/9(F-32) = 5/9*9/5 C

5/9(F-32) = C

Final answer:

To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 (or 1.8) and then add 32. For example, to convert 20 degrees Celsius to Fahrenheit: (9/5) * 20 = 36, and then add 32 to get 68 degrees Fahrenheit.

Explanation:

To solve the formula for converting temperature from degrees Celsius (C) to degrees Fahrenheit (F), you start with the given equation:

F = [tex]\frac{9}{5}[/tex]+ 32

This equation allows you to convert a temperature from Celsius to Fahrenheit by multiplying the Celsius temperature by 9/5 (or 1.8) and then adding 32. The formula reflects the fact that the Fahrenheit scale has a freezing point at 32 degrees higher than the Celsius scale's freezing point, and that each degree Celsius is equivalent to 1.8 degrees Fahrenheit. Here's a step-by-step explanation to convert Celsius to Fahrenheit:

Multiply the Celsius temperature by 9/5.

Add 32 to the result of this multiplication to get the temperature in Fahrenheit.

For instance, to convert 20 degrees Celsius to Fahrenheit:

(9/5) * 20 = 36

36 + 32 = 68 degrees Fahrenheit.

Hence, 20 degrees Celsius is equal to 68 degrees Fahrenheit when you apply the temperature conversion formula.

An oblique prism is created using rhombuses with edge lengths of 25 units. The area of one rhombus is 600 sq units. The perpendicular distance between the bases is 24 units. What is the volume of the prism?

Answers

Check the picture below.

let's recall Cavalieri's principle, that solids with equal altitudes and identitical cross-sectional areas at each part all the way up, have the same volume.

so, for a prism like this that is not oblique, with rhombic bases of area 600 and a height/altitude of 24, the volume will simply be the base * height, 600 * 24 = 14400.

well, based on Cavalieri's principle, an oblique one will also have the same volume.

Answer:

The volume of the prism is 14400 units³.

Step-by-step explanation:

It is given that an oblique prism is created using rhombuses with edge lengths of 25 units.

The volume of a prism is

[tex]V=B\times h[/tex]                   ..... (1)

Where, B is base area and h is height of the prism.

It is given that the area of one rhombus is 600 sq units. The perpendicular distance between the bases is 24 units.

Substitute B=600 and h=24 in equation (1) to find the volume of the prism.

[tex]V=600\times 24[/tex]

[tex]V=14400[/tex]

Therefore the volume of the prism is 14400 units³.
