What is the selling price?
The cost a consumer pays to purchase a good or a commodity is known as the selling price. It is a price that is higher than the cost price and includes a profit margin. The cost of an item when acquired is referred to as its selling price (S.P.).
Here, we have
Given: A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation.
y = -3x² + 239x - 2268
At a maximum profit, dy/dx = 0, hence:
dy/dx = -6x + 239

Answers
The statement which is correct is: If {α, β} is independent, then {w₁, w₂, w₁+ w₂} is in dependent.
In vector space theory, a set of vectors is said to be linearly independent if there is no non-trivial linear combination of vectors equal to vector zero. If such a linear combination exists, the vectors are said to be linearly dependent. These concepts are central to dimension definitions.
The definition of linear dependence and the ability to determine whether a subset of vectors in a vector space are linearly dependent is essential to determining the dimensionality of a vector space.
According to the Question, we know that:
{w₁, w₂, w₃} are linearly independent.
Let, α₁, α₂, α₃ such that
α₁w₁ + α₂w₂+ α₃w₃ = 0
and, α₁ = α₂ = α₃ = 0
Again considering the following, we can say that:
{w₁, w₁+ w₂, w₁+w₂+w₃} such that:
β₁(w₁) + β₂(w₁+ w₂) + β₃(w₁+ w₂+ w₃) = 0
Here, the dependent variable is {α,β} and { w₁+ w₂+ w₃}

It should be noted that the function that can model the data is a linear function since there's a constant difference or -5.The linear function is y = -5x - 9.
How to explain the function.In this case, to determine whether the data is best modeled by a linear, quadratic, or exponential function, we can first plot the data points and see what type of curve they form. However, since we are only given five data points, it can be difficult to make a definitive determination.
One way to estimate the type of function is to look at the differences between the y values. For example, if the differences between the y values increase by a constant amount, then the data may be best modeled by a linear function. If the differences increase by a constant squared amount, then the data may be best modeled by a quadratic function.

8) Use a proportion to solve this problem: Two towns are 460 km apart. If the scale on the map is 3 cm to 45 km, how far apart are the towns on the map?
Answers
The distance between the two towns on the map was found to be 30.67 centimeters by setting up and solving a proportion between the distances on the map and the actual distances.
The problem provides us with a scale on the map of 3 cm to 45 km, which means that every 3 centimeters on the map represents 45 kilometers in the actual world. Let x be the distance between the two towns on the map in centimeters. Using the proportion, we can set up the relationship between the distances on the map and the actual distances as follows:
3 cm / 45 km = x cm / 460 km
Here, we set up a ratio between the distance on the map and the actual distance, where the distance on the map is x centimeters and the actual distance between the towns is 460 kilometers. We can then cross-multiply to solve for x:
45 km * x cm = 3 cm * 460 km
This gives us:
45x = 1380
x = 1380 / 45
x = 30.67 cm
Therefore, the distance between the two towns on the map is 30.67 centimeters.

a truck hauled 136 cubic feet of sand to a construction site. the sand dumped into a cone shaped pile 6 feet in height. what is the approximate diameter of sand in feet?
Answers
The approximate diameter of the pile of sand in the cone that sand was dumped in is 9.30 feet.
What is the approximate diameter?
A cone is a 3-dimensional object that consists of a ciruclar base and a vertex. The diameter is twice the length of the radius.
Radius = √[volume / (1/3 x π x height)]
=> Radius=√[136 / (1/3 x 22/7 x 6)]
=> Radius=√[136 / 6.29 = 4.65

A ladder is placed against a building forming an angle of elevation of 52. If it reaches the building 12 feet above the ground, how far is the foot of the ladder from the building?
Answers
We can use trigonometry to solve this problem. Let x be the distance from the foot of the ladder to the building, and let y be the length of the ladder. Then, we have:
tan(52) = y/x (since tangent = opposite/adjacent, and y is opposite to the angle of elevation and x is adjacent)
We also know that the ladder reaches 12 feet above the ground, so we have:
y = 12 + x (since y is the hypotenuse of the right triangle formed by the ladder, the ground, and the building)
We can substitute the second equation into the first to get:
tan(52) = (12 + x)/x
Simplifying this equation, we get:
tan(52)x = 12 + x
Using a calculator to find the tangent of 52, we get:
1.2799x = 12 + x
Solving for x, we get:
0.2799x = 12
x = 42.87 feet (rounded to two decimal places)
Therefore, the foot of the ladder is approximately 42.87 feet away from the building.

John deposits $5025 into a savings account that has an interest rate of 9.5%. The account is compounded monthly for the next 18 years. So in the account the amount will be $27596.60. Option c is correct.
What is compound interest?Cοmpοund interest, alsο knοwn as interest οn principle and interest, is the practise οf adding interest tο the initial amοunt οf a lοan οr depοsit. It οccurs when interest is reinvested, οr added tο the bοrrοwed capital rather than paid οut, οr when the bοrrοwer is required tο pay it, sο that interest is made the fοllοwing periοd οn the initial amοunt + any accumulated interest. In business and ecοnοmy, cοmpοund interest is cοmmοn.
We can use the Cοmpοund interest below-
[tex]\rm A = P(1 + \frac{r}{n})^{nt}[/tex]
where,
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Given,
Time periods (t)= 18years
n = 12 months
Interest in a year (r)= 9.5% or 0.095
Principial amount (P)= $5025
Lets solve for final amount :

Step-by-step explanation:
To calculate the measure of the sector that represents the probability of a rainy day using a spinner, we need to first determine the angle of the sector that represents the probability of a rainy day.
The probability of a rainy day is given as P(raining) = 0.34, which means that out of 100 days, 34 are rainy. Therefore, we can express the angle of the sector as:
Angle of sector = Probability of rain * Total angle of the spinner = 0.34 * 360 = 122.4 (rounded to the nearest degree)
So the measure of the sector that represents the probability of a rainy day is 122 degrees (rounded to the nearest degree).
Therefore, the answer is 122 degrees.
Answer:122°

There is a rule of sides in a triangle that states "the sum of the lengths of two sides is always greater than the third side"
so how you would solve this is by process of elimination. Add two lengths from each number set to see if they follow the rule.
When you do this, all of the number sets follow the rule except for the first one, because 4 plus 17 is 21, and it is less than 23. This means it does not follow the rule.

Un constructor debe decidir entre rentar o comprar una máquina excavadora. Si fuese a rentar la máquina, el costo de la renta sería de $3,000 mensuales (sobre la base de un año) y el costo diario (gas, aceite y operador) sería de $180 por cada día que la máquina se utilice. Si él fuese a comprarla, sus costos fijos anuales serían de $20,000 y los costos diarios de operación y mantenimiento serían de $230 por cada día que la máquina se utilizara. ¿Cuántos días al año por lo menos, tendría que utilizar el constructor la máquina para justificar la renta en lugar de la compra?
Answers
Answer:
Para decidir si es mejor rentar o comprar la máquina excavadora, se debe calcular el costo anual de cada opción y compararlos.
Costo anual de renta = Costo de renta mensual x 12 meses + (Costo diario x Días de uso)
Costo anual de renta = 3000 x 12 + (180 x Días de uso)
Costo anual de renta = 36000 + 180D
Costo anual de compra = Costo fijo anual + (Costo diario x Días de uso)
Costo anual de compra = 20000 + (230 x Días de uso)
Para encontrar el número mínimo de días de uso que justificarían la renta en lugar de la compra, se debe igualar ambos costos anuales:
36000 + 180D = 20000 + 230D
50D = 16000
D = 320
Por lo tanto, el constructor tendría que utilizar la máquina excavadora al menos 320 días al año para justificar la renta en lugar de la compra.

Value of base and hypotenuse of triangle are 9√3 and 18 respectively.
Define right triangleA right triangle is a triangle with one interior angle measuring 90 degrees, known as a right angle. The side opposite to the right angle is called the hypotenuse, and the other two sides are known as the legs of the right triangle. The length of the hypotenuse can be found using the Pythagorean theorem, that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.
Height of triangle=9

How much do we need to invest each month at a rate of 8% compounded monthly so that we have a total of $600,000 saved in 25 years?
Please help will mark brainliest
Answers
Answer:$163.68
Step-by-step explanation:
We can use the formula for compound interest to solve this problem:
A = P(1 + r/n)^(nt)
where:
A = final amount ($600,000)
P = initial amount (unknown)
r = interest rate (8%)
n = number of times interest is compounded per year (12 for monthly)
t = time in years (25)
Substituting in the values, we get:
$600,000 = P(1 + 0.08/12)^(12*25)
Simplifying:
$600,000 = P(1.00666666666667)^300
Dividing both sides by (1.00666666666667)^300:
P = $600,000 / (1.00666666666667)^300
Using a calculator, we get:
P = $163.68
Therefore, we would need to invest $163.68 each month at a rate of 8% compounded monthly to have a total of $600,000 saved in 25 years.

Triangles and circles have a close relationship in geometry, and several interesting properties and theorems connect them.
One triangle inscribed in circle: This statement is true, and it refers to the property of a circle that can be inscribed in a triangle. In other words, if we draw a circle that passes through all three vertices of a triangle, then the triangle is said to be inscribed in the circle. The center of the circle is called the circumcenter of the triangle, and it is the intersection point of the perpendicular bisectors of the sides.
Many triangles inscribed in circle: This statement is also true, as there are many different triangles that can be inscribed in the same circle. For example, if we draw a circle and pick any three points on its circumference, then we can connect these points to form a triangle that is inscribed in the circle.
One circle inscribed in triangle: This statement is true, and it refers to the property of a triangle that can be inscribed in a circle. In other words, if we draw a circle that is tangent to all three sides of a triangle, then the circle is said to be inscribed in the triangle. The center of the circle is called the incenter of the triangle, and it is the intersection point of the angle bisectors.
Many circles inscribed in triangle: This statement is false, as there can only be one circle that is inscribed in a given triangle. However, there are other circles that can be associated with a triangle, such as the circumcircle and the excircles. The circumcircle is the circle that passes through all three vertices of the triangle, while the excircles are the circles that are tangent to one side of the triangle and the extensions of the other two sides.
In summary, triangles and circles are closely related in geometry, and their properties and theorems are important in various areas of mathematics and science.

An uncapped fibre contract originally cost R990 per month. It has now fallen in price to R765 per month. What is the percentage decrease in the monthly price of the contract?
Answers
Answer:
To find the percentage decrease, we need to find the difference between the original price and the new price, divide that difference by the original price, and then multiply by 100 to express the result as a percentage.
The difference between the original price and the new price is:
990 - 765 = 225
Dividing the difference by the original price gives:
225 ÷ 990 ≈ 0.227
Multiplying by 100 gives:
0.227 x 100 ≈ 22.7
Therefore, the percentage decrease in the monthly price of the contract is approximately 22.7%.
