The expression for the function f(x) in standard form if the function f(x) is divided by x-2 is f(x) = 3x³ + 2x² - 20x + 17.

The function that when divided by 2x + 1, the quotient is x² - 8x + 8 and the remainder is 5 is determined as follows:

f(x) = (2x + 1)(x² - 8x + 8) + 5

Simplifying the above gives the following:

f(x) = 2x³ - 16x² + 16x + x² - 8x + 8 + 5

f(x) = 3x³ - 15x² + 8x + 13

Manufacturing should pay $2206.80, Selling should pay $7356.0and Administration should pay $2452.00

Generally, To find out how much each department should pay, you can use the proportion of the cost that corresponds to their respective ratio.

First, calculate the total ratio by adding the three ratios together:

1/10 + 1/3 + 1/9 = 0.544

Then, divide the total cost by the total ratio to find the unit cost:

$12,005 / 0.544 = $22068.01

Next, multiply the unit cost by the ratio for each department to find out how much they should pay:

Manufacturing: $22068.01 x 1/10 = $2206.80

Selling: $22068.01 x 1/3 = $7356.0

Administration: $22068.01 x 1/9 = $2452.00

Answer:

1 or 0

Step-by-step explanation:

in order for a number's square equals to itself, it has to be 1 or 0.

The earliest time at which they can be finished moving all of the boxes is: d. 9:44 a.m

To determine the earliest time at which Quincy and Celine can finish moving all of the boxes, we need to determine the maximum amount of time it will take for them to move all of the boxes. We can do this by calculating the time it will take for each person to move each type of box individually, and then adding those times together.

Quincy takes 1 minute to move a small box and 2 minutes to move a large box. Celine takes 2 minutes to move a small box and 3 minutes to move a large box.

Time to move 16 small boxes: 16 boxes * 1 minute/box = 16 minutes

Time to move 10 large boxes: 10 boxes * 2 minutes/box = 20 minutes

Total time for Quincy: 16 minutes + 20 minutes = 36 minutes

Time to move 16 small boxes: 16 boxes * 2 minutes/box = 32 minutes

Time to move 10 large boxes: 10 boxes * 3 minutes/box = 30 minutes

Total time for Celine: 32 minutes + 30 minutes = 62 minutes

To get the earliest time they can finish moving all the boxes, we take the maximum of the two times:

Max(36 minutes, 62 minutes) = 62 minutes

Start time: 9:00 a.m.

End time: 9:00 a.m. + 62 minutes = 9:62 a.m.

So the earliest time they can finish moving all the boxes is 9:62 a.m.

Answer: A quadratic of the form $ax^2 + bx + c$ has rational roots if and only if its discriminant, $b^2 - 4ac$, is a perfect square. In this case, the discriminant is $(20)^2 - 4(3)(c) = 400 - 12c$. So, we need to find the positive integers $c < 100$ that make $12c$ a perfect square.

The perfect squares that are less than $100$ are $1,4,9,16,25,36,49,64,81$, so the possible values for $c$ are $33,44,55,66,77,88$.

So, the positive integers $c$, with $c < 100$, that make the quadratic have rational roots are $33,44,55,66,77,88$

The  Pinewoods Trail is longer than the Outlook Trail.

The definition of a fraction is a portion of a whole. A single object or a collection of objects might be entire. When we cut a piece of cake in real life from the entire cake, the part represents the percent of the cake. The word "fraction" is derived from Latin. "Fractus" means "broken" in Latin.

Given the length of Lake Trail = 4 and 3/5 mile

length of Lake Trail = 23/5 miles

length of Outlook Trail = 5 and 5/6 mile

length of Outlook Trail = 35/6 miles

length of Pinewoods Trail = 1 and 3/10 miles longer than Lake Trail

length of Pinewoods Trail = 33/10 + 23/5

length of Pinewoods Trail = (33 + 46)/10

length of Pinewoods Trail = 79/10 miles

comparing the length of  Outlook Trail  and  Pinewoods Trail,

which is 35/6 and 79/10 miles respectively,

the common denominator for both is 30,

35/6 = (35*5)/(6*5)

35/6 = 175/30

and 79/10 = (79*3)/(10*3)

79/10 = 273/30

here 273/30 > 175/30

Hence  Pinewoods Trail is longer.

The area of the glacier at the start of last year was 56.31 km², based on a percentage reduction of 0.2%.

A percentage decrease represents the difference between the starting and ending values, expressed as a percentage of the starting value.

In working out the percentage reduction, we determine the difference between the ending and starting values.  This difference is divided by the starting value and multiplied by 100.

The current area of the glacier = 56.20 km²

The percentage reduction = 0.2%

Proportionately, the current area, in percentage terms = 99.8% (1 - 0.2%)

99.8% = 56.20 km²

100% = 56.31 km²

Thus, to 2 decimal points, the area of the glacier at the start of last year was 56.31 km².

Total distance travelled by the cyclist is 131/40 km in fraction.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a correct fraction is smaller than the denominator.

The three main sorts of fractions are as follows. Proper fractions, improper fractions, and mixed fractions are these three types. The expressions with a numerator and a denominator are called fractions. We categorize its kinds based on these two parameters.

We can conclude that the division property of equality was done between step 4 and step 5.

What is linear equation ?

Linear equation can be defined as the equation in which the highest degree is one.

The Division Property of Equality states that when both sides of an equation are divided by the same nonzero number, both sides remain equal.

That is, if a, b, and c are real numbers such that a = b and c ≠0, then  

a/c = b/c

At step 4: The equation was -6x = 57

To move to step 5, Paula had to divide both sides by the co-efficient of x (-6) in order to get the value of x. See below

-6x = 57

---- Divide both sides by -6 (Step 4)

-6x / -6  = 57 / -6

Answer:

If angle ABD = 60°, then angle BDC can be found using the fact that the measures of the angles in a triangle add up to 180°.

So, m(angle BDC) = 180 - (m(angle ABD) + m(angle BDA))

Therefore, m(angle BDC) = 180 - (60 + m(angle BDA))

So the measure of angle BDC is not fixed, it depends on the measure of angle BDA.

Take the original data and divide it by the standard deviation to determine the z-scores. X is a symbol for the relevant data point. For the population from which you selected your sample, mu and sigma stand in for the mean and standard deviation.

In terms of standard deviations above or below the mean, a data point's z-score quantifies this exact distance.

A z-score is calculated using the following formula:

data point = mean standard deviation

Data point means with standard deviation equal to z

The same equation is given below in symbol form:

z=  x−μ / σ

Some significant z-score details are as follows:

An elevated z-score indicates that the data point is.

When a data point has a negative z-score, it is below average.

The data point is considered to be roughly average if the z-score is near to 0.00.

If a data point's z-score is higher or lower than 3 33 or 3 3minus, the data point is deemed uncommon.

At Almond, the average score on a history midterm is

c) The true interest rate paid on the discounted loan is 4.1%.

A discount loan is a type of loan in which the interest (cost of borrowing) is deducted upfront or at the time the loan is granted.

The implication of getting a discount loan is that the amount received is less than the principal amount because the grantor has reduced it by interest and other fees (finance charges).

The principal = $13,300

Discount rate = 3¹/₂%

Time = 4 years

Discount = $1,862 ($13,300 x 3.5% x 4)
