A boat has a top speed of 26 knots and a displacement of approximately 93,000 tons. Express the top speed in miles per hour and the displacement in metric tons
The boat's displacement is approximately 84,016.8 metric tons.
How to convert from knots to miles?To convert the boat's top speed from knots to miles per hour, we can use the conversion factor of 1.15078 miles per hour per knot:
26 knots × 1.15078 miles per hour per knot = 29.86 miles per hour (rounded to two decimal places)
Therefore, the boat's top speed is approximately 29.86 miles per hour.
To convert the boat's displacement from tons to metric tons, we can use the conversion factor of 0.907185 metric tons per ton:
93,000 tons × 0.907185 metric tons per ton = 84,016.8 metric tons (rounded to one decimal place)
Therefore, the boat's displacement is approximately 84,016.8 metric tons.

The polynomial function f(x) = x³ - 4x²-3x + 18 has (x+2) as one of its linear factors. Use long division to find the other linear factors.
Separate multiple factors with a comma. If there are any repeated factors, only write them once.
The complete factorization of the polynomial function f(x) = x³ - 4x² - 3x + 18 is (x + 2)(x - 22).
What is a polynomial ?
A polynomial is a mathematical expression involving a sum of powers in one or more variables (indeterminates) multiplied by coefficients.
where n is a non-negative integer (the degree of the polynomial), x is the variable, and (the coefficients of the polynomial). The highest power of x in the expression is n, and this term is called the leading term. The coefficient of the leading term, a_n, is called the leading coefficient.
To find the other linear factors of the polynomial function f(x) = x³ - 4x² - 3x + 18, we can use long division by dividing the polynomial function by (x + 2).
Here's how the long division would look like:
x³ - 4x² - 3x + 18
÷ x + 2
__________________________
x² - 6x - 20
÷ x + 2
__________________________
x - 22
÷ x + 2
__________________________
-20
here -20 is the remainder.
The complete factorization of the polynomial function f(x) = x³ - 4x² - 3x + 18 is (x + 2)(x - 22).
So, the other linear factors are x - 22.
Therefore, The complete factorization of the polynomial function f(x) = x³ - 4x² - 3x + 18 is (x + 2)(x - 22).

Credit Sales $ 400,000
In addition, its unadjusted trial balance includes the following items.
Accounts receivable $ 120,000 debit
Allowance for doubtful accounts $ 1,400 debit
Bad debts are estimated to be 2% of credit sales. Show how Accounts Receivable and the Allowance for Doubtful Accounts appear
on its December 31 balance sheet.
Current Assets:
Accounts receivable $120,000
Less: Allowance for doubtful accounts $???
Answer:
To determine the balance in the Allowance for Doubtful Accounts on December 31, we first need to estimate the bad debts based on the credit sales.
Bad debts = 2% of credit sales = 2% * $400,000 = $8,000
The balance in the Allowance for Doubtful Accounts would then be equal to the estimated bad debts, which is $8,000.
Therefore, the Accounts Receivable and the Allowance for Doubtful Accounts would appear on the December 31 balance sheet as follows:
Current Assets:
Accounts receivable $120,000
Less: Allowance for doubtful accounts $8,000
Net accounts receivable $112,000

How many bees would equal the
weight of a moose? (Give your
answer in standard form.)
The number of bees that will equal the mass of a single moose is 5 × 10⁶.
How many bees would equal the weight of a moose?Given the data in the question;
Mass of one bee = 2.5 × 10⁻⁴ poundsMass of one moose = 1.25 × 10³ poundsTo determine the number of bees that will equal the mass of a single moose.
Let the number be represented by x.
Hence;
Number of bees × mass of bee = mass of moose
n × ( 2.5 × 10⁻⁴ ) = 1.25 × 10³
Divide both sides by ( 2.5 × 10⁻⁴ ).
n = ( 1.25 × 10³ ) / ( 2.5 × 10⁻⁴ )
n = 1250 / 0.00025
n = 5,000,000

2. The slant height is, 28.14 mm.
3. The ant crawl to get from the base of the cone to the top of the hill is, 28.14 mm.
What is Volume?In mathematics, Space occupied by three dimensional objects is called Volume. Basically it is a space within a closed region of every three dimensional object.
The volume of cone V = (1/3)πr²h
Given that,
The volume = 8792 mm³
1. by using the formula to solve for h,
we get h = (3V)/(πr²).
Plugging in the values given,
we have h = (3(8792 mm³))/(π(20 mm)²) ≈ 22.18 mm.
Therefore, the height of the cone is approximately 22.18 mm.
2. it is known that, from the Pythagoras theorem
s² = h² + r²,
where s is the slant height, h is the height, and r is the radius.
Plugging in the values we found in part 1,
we have s² = (22.18 mm)² + (20 mm)² ≈ 791.88 mm².
Taking the square root of both sides, we get s ≈ 28.14 mm.
Therefore, the slant height is approximately 28.14 mm.
3. To find the distance the ant crawls to get from the base of the cone to the top of the hill, we need to find the length of the slant height.
Using the value we found in part 2,
the length of the slant height is approximately 28.14 mm.
Therefore, that is the distance the ant would crawl to get from the base of the cone to the top of the hill.

Identify the function type that could represent the data in the table. Explain your reasoning.
Type your response in the box.
A quadratic function could represent the data in the table, as the increase rate decreases as x increases, meaning that the function could be approaching it's vertex.
How to classify the function?Traditionally, functions are classified as either linear or exponential, as follows:
Linear: constant increase.Exponent: multiplicative increase.As there is not a constant neither a multiplicative rate of change for the table, the function is neither linear nor exponential.
Considering that from x = 1 to x = 4 the rate of change is of 4/3, while from x = 16 to x = 25 the rate of change is of 4/9, that is, the increase rate decreases as x increases, the function is classified as a quadratic function.

a toy manufacturer needs a piece of plastic in the shape of a right triangle with one leg 5 cm longer than the other and the hypotenuse 10 cm longer than the shorter leg. what is the perimeter of the triangle
The triangle's perimeter is roughly 25.29 cm.
In arithmetic, what is perimeter?The area around a form's edge is known as its perimeter. The perimeter of various forms can be calculated by summing the lengths of their sides.
Let's call the right triangle's shorter leg "x" for short.
The longer leg is then 5 cm longer than x, or x + 5, according to the situation.
The hypotenuse measures x + 10 cm longer than x.
By the Pythagorean theorem, we know that:
x² + (x+5)² = (x+10)²
Expanding and simplifying this equation gives:
2x² + 10x - 75 = 0
Dividing both sides by 2 gives:
x² + 5x - 37.5 = 0
We can find the value of x by using the quadratic formula:
x = (-5 ± sqrt(5² - 4(1)(-37.5))) / 2
x = (-5 ± sqrt(175)) / 2
x ≈ -8.68 or x ≈ 3.43
Since x represents a length, we must choose the positive solution x = 3.43 cm.
Therefore, the shorter leg of the triangle is 3.43 cm, the longer leg is 8.43 cm (3.43 + 5), and the hypotenuse is 13.43 cm (3.43 + 10). The perimeter of the triangle is the sum of the three sides, which is:
3.43 + 8.43 + 13.43 = 25.29 cm
