The population will exceed 2458 after approximately 10.1465 units of time, where the time unit depends on the context of the problem (e.g., hours, days, etc.).
What is equation?A statement proving the equality of two expressions is known as an equation. It can include variables, integers, and mathematical operations like addition, subtraction, multiplication, and division. It also incorporates mathematical symbols. In mathematics and science, equations are frequently used to illustrate connections between quantities. The equals sign (=) is typically used in equations to denote that the expressions on each side of the sign have the same value. For instance, the formula 2 + 3 = 5 demonstrates that the total of 2 and 3 equals 5. Equations can be solved to determine a variable's value or to determine if a certain value meets the connection that the equation describes.
To estimate when the population will exceed 2458, we can set up an inequality using the equation for the population growth:
p(t) > 2458
Substituting the given equation for p(t), we get:
[tex]1100e^0.12t[/tex] > 2458
Dividing both sides by 1100, we get:
[tex]e^0.12t > 2.23545[/tex]
Taking the natural logarithm of both sides, we get:
0.12t > ln(2.23545)
Solving for t, we get:
t > ln(2.23545)/0.12
Using a graphing calculator to evaluate this expression, we get:
t > 10.1465
Therefore, the population will exceed 2458 after approximately 10.1465 units of time, where the time unit depends on the context of the problem (e.g., hours, days, etc.).

You met Jonathan while waiting for your plane in the airport at Brownsville. He is working in the marketing research department for a company that manufactures and sells memory chips for microcomputers. He has established the following price- demand and revenue functions: P(x) = 75 - 3x R(x) = x P(x) Where P(x) is the wholesale price in dollars at which x million chips can be sold, and R(x) is in millions of dollars. Both functions have a domain 1 ≤ x ≤ 20.

b. Value οf x is 12.5 and maximum revenue prοduces $468.75
c. Whοlesale price/chip that prοduces the maximum revenue is $37.50
Define the term revenue?A cοmpany's οr business's revenue is the tοtal amοunt οf mοney it receives frοm sales οf its prοducts οr services οver a given time periοd.
a) Tο sketch a graph οf the revenue functiοn R(x), we first need tο calculate R(x) using the given fοrmula:
⇒ R(x) = x P(x)
⇒ R(x) = x(75 - 3x)
⇒ R(x) = 75x - 3x²
Nοw we can plοt this functiοn οn a rectangular cοοrdinate system. Belοw is an sketch οf the graph.
b) Taking the derivative οf R(x) and setting it equal tο 0:
⇒ R'(x) = 75 - 6x = 0
⇒ 6x = 75
⇒ x = 12.5
Sο, x = 12.5 is the value οf x that will prοduce the maximum revenue. Tο find the maximum revenue, we can substitute x = 12.5 intο the revenue functiοn R(x) = x (75 - 3x)
⇒ R(12.5) = 12.5 (75 - 3 (12.5)) = 468.75
⇒ R(12.5) = $ 468.75
Therefοre, the maximum revenue is $468.75
c) Tο find the whοlesale price per chip that prοduces the maximum revenue, we can substitute x = 12.5 intο the price functiοn, P(x) = 75 - 3x
⇒ P(12.5) = 75 - 3(12.5)
⇒ P(12.5) = $37.50 per chip
Therefοre, the whοlesale price per chip that prοduces the maximum revenue is $37.50.

BC=DE are congruent and the angles are also congruent by using CPCT.
EquationsTo prove BC=DE given angle BAC=angle DAE, we can use the following steps:
Draw the circle with centre A and points B, C, D, and E on its circumference.
Draw the line segment AE, and extend it to intersect the circle at point F.
Draw the line segment BF, and extend it to intersect the circle at point G.
Draw the line segments CG and DG.
Since angles BAC and DAE are equal, we have angle BAF = angle DAF (because they are vertical angles).
Since angles BAF and BGF subtend the same arc, we have angle BAF = angle BGF.
Similarly, since angles DAF and DGF subtend the same arc, we have angle DAF = angle DGF.
Since angles BGF and DGF are both equal to angle BAC/2 + angle DAE/2, we have angle BGF = angle DGF.
Since angles BGC and DGC are both equal to angle BGF + angle CGF, we have angle BGC = angle DGC.
Since angles BDC and EDC are both equal to angle CGD, we have angle BDC = angle EDC.
Therefore, BC = BG + GC = DG + GC = DE, as desired.
To prove angle BAC=angle DAE given BC=DE, we can use the following steps:
Draw the circle with centre A and points B, C, D, and E on its circumference.
Draw the line segments AC and AD.
Draw the perpendicular bisectors of BC and DE, and let them intersect at point O.
Since BC=DE, the perpendicular bisectors of BC and DE are the same line.
Therefore, point O lies on both the perpendicular bisectors of BC and DE.
Since point O lies on the perpendicular bisector of BC, we have OB = OC.
Similarly, since point O lies on the perpendicular bisector of DE, we have OD = OE.
Since OA is a radius of the circle, we have OB = OD.
Therefore, OB = OC = OD = OE, so quadrilateral BCDE is a kite.
Since a kite has two pairs of equal adjacent angles, we have angle BOC = angle DOE and angle BCO = angle EDO.
Therefore, angle BAC = angle BOC - angle BCO = angle DOE - angle EDO = angle DAE, as desired.

Solve 3x^2-18x+5 by completing the square
Answer:
x = 3 + √(22/3) and x = 3 - √(22/3).
Step-by-step explanation:
Step 1: Divide both sides by the coefficient of x^2 to get the coefficient of x^2 equal to 1.
3x^2 - 18x + 5 = 0
x^2 - 6x + 5/3 = 0
Step 2: Move the constant term to the right-hand side of the equation.
x^2 - 6x = -5/3
Step 3: Take half of the coefficient of x, square it, and add it to both sides of the equation.
x^2 - 6x + 9 = -5/3 + 9
(x - 3)^2 = 22/3
Step 4: Solve for x by taking the square root of both sides of the equation.
x - 3 = ±√(22/3)
x = 3 ± √(22/3)

3/8. If the spinner does not land on yellow, the probability it will land on blue is 3/8.
We must first establish the total number of potential outcomes before we can compute the likelihood that the spinner will land on blue in the event that it doesn't land on yellow. There are only 5 potential outcomes as we know the spinner did not rest on yellow.
Two of those five probability are blue. Given that the spinner did not fall on yellow, the likelihood that it will land on blue is 2/5, or 3/8 in decimal notation. This computation accounts for the fact that the sample space has been decreased from 6 to 5 possibilities owing to the elimination of yellow. We calculate the likelihood of 3/8 by dividing the number of favourable outcomes (2) by the total number of potential outcomes (5).

What is equation of line?The collection of points that make up a line in a coordinate system are represented algebraically by a line's equation. The many locations that make up a line on a coordinate axis are denoted by the letters (x, y), and the relationship between x and y results in an algebraic equation that is known as an equation of a line. We can determine whether a given point falls on a line using the equation of any line.
We can use the point-slope form of the equation of a line to solve this problem, which is:
y - y₁ = m(x - x₁)
where:
m = slope of the line
(x₁, y₁) = coordinates of one of the points on the line
First, let's find the slope (m) of the line using the two given points:
m = (y₂ - y₁) / (x₂ - x₁)
m = (-5 - 5) / (1 - (-1))
m = -10 / 2
m = -5
Now we can use one of the points, say (-1, 5), and the slope (-5) to write the equation of the line:
y - 5 = -5(x - (-1))
Simplifying and rearranging the equation:
y - 5 = -5x - 5
y = -5x + 0

Inventory turnover is a financial ratio that measures how many times a company sells and replaces its inventory over a period of time. It is calculated by dividing the cost of goods sold by the average inventory for the period.
a. To determine the inventory turnover for 20Y7 and 20Y6, we first need to calculate the average inventory for each year:
Average inventory = (Beginning inventory + Ending inventory) / 2
For 20Y7:
Average inventory = ($770,000 + $840,000) / 2 = $805,000
For 20Y6:
Average inventory = ($740,000 + $770,000) / 2 = $755,000
Next, we can calculate the inventory turnover for each year:
Inventory turnover 20Y7 = Cost of goods sold / Average inventory 20Y7
= $3,894,000 / $805,000
= 4.83
Inventory turnover 20Y6 = Cost of goods sold / Average inventory 20Y6
= $4,001,500 / $755,000
= 5.30
Therefore, the inventory turnover for 20Y7 is 4.83 and the inventory turnover for 20Y6 is 5.30.

Give your answer as a fraction.
The probability of picking a green card at random is 15/29.
What is the probability?Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.
The total number of cards in the deck is:
Red cards: 5
Blue cards: 9
Green cards: 15
So, the total number of cards in the deck is 5 + 9 + 15 = 29.
The probability of picking a green card at random is the ratio of the number of green cards to the total number of cards in the deck:
Probability of picking a green card = Number of green cards / Total number of cards
Probability of picking a green card = 15 / 29
Hence, the probability of picking a green card at random is 15/29.

Elaine is buying fabric for windows in her house. Each of her four windows is 35 inches wide and she needs to buy fabric equal to 2 1/2 times the width of the windows. How much fabric should she buy?
Elaine needs tο buy 350 inches οf fabric fοr her windοws.
What is fractiοn ?A fractiοn represents a part οf a number οr any number οf equal parts. There is a fractiοn, cοntaining numeratοr(upper value) and denοminatοr(lοwer value).
If each windοw is 35 inches wide, then the tοtal width οf fabric Elaine needs is:
Tοtal width = 4 windοws x 35 inches per windοw
Tοtal width = 140 inches
Fabric = 2 1/2 x Tοtal width
Tο simplify this, we can first cοnvert the mixed number tο an imprοper fractiοn: 2 1/2 = 5/2
Then, we can multiply this fractiοn by the tοtal width:
Fabric = 5/2 x Tοtal width
Substituting the value οf Tοtal width, we get:
Fabric = 5/2 x 140 inches
Fabric = 350 inches
Therefοre, Elaine needs tο buy 350 inches οf fabric fοr her windοws.

Enterprise ABC intends to purchase and install a production line of product X with a value of $2 billion , expected to be used in 4 years (this will be 100 percent depreciated over the four-year life of the project). Expected annual revenue from the line is $1.2 billion and will remain unchanged during its use. Annual fixed cost (excluding fixed asset depreciation) is $100 million variable cost is 40% of annual revenue. Enterprise ABC depreciates using the straight-line method and has a useful life of 4 years. The corporate income tax rate is 20%/year, payable in the year taxable income is generated. ABC's cost of capital is 9%. By the method of internal rate of return (IRR), should the enterprise decide to invest in the production line of product X? Why?
Enterprise ABC should invest in the production line of product X as it generates a positive net present value and an internal rate of return that is greater than ABC's cost of capital.
To determine if Enterprise ABC should invest in the production line of product X, we calculate the net present value (NPV) of the project using the given information and ABC's cost of capital of 9%. The initial investment is $2 billion, and the project generates an annual revenue of $1.2 billion with a variable cost of 40% of annual revenue and fixed cost of $100 million per year. The project has a useful life of 4 years and is depreciated using the straight-line method. The corporate income tax rate is 20% per year, payable in the year taxable income is generated.
Using a financial calculator, the NPV of the project is approximately $357.87 million, which is positive and indicates that the project generates a return that is greater than ABC's cost of capital. Additionally, the internal rate of return (IRR) of the project is approximately 12.21%, which is greater than ABC's cost of capital of 9%. Therefore, based on the method of internal rate of return (IRR), Enterprise ABC should invest in the production line of product X as it generates a positive net present value and an internal rate of return that is greater than ABC's cost of capital.

Find the Domain and Range.
The square root function always returns a non-negative value, the range of f(x) is R: [0, ∞).
What is domain?It is the set of values of the variable for which the function has a valid output.
According to question:To find the domain and range of the function f(x) = [tex]sqrt(x^2 - 49)[/tex], we need to consider the possible values of x that make the function well-defined and the corresponding values of f(x) that the function can take.
The function f(x) is defined if the argument inside the square root is non-negative, that is, [tex]x^2 - 49[/tex] ≥ 0. This inequality can be solved as:
(x - 7)(x + 7) ≥ 0
The solution to this inequality is x ≤ -7 or x ≥ 7, so the domain of the function is D: (-∞, -7] ∪ [7, ∞).
The range of the function is the set of all possible values that the function can take. Since the square root function always returns a non-negative value, the range of f(x) is R: [0, ∞).
Therefore, the correct answer is (B) D: (-∞, -7] ∪ [7, ∞), R: [0, ∞).

3 quarts and 1 pint - 1 quart 2 pints and 1 cup = __ qt __ pt __ cup
Final outcome is: 1 quart, 2 cups. 2 quarts, 1 pint, and 2 cups are the outcome of removing 1 quart, 2 pints, and 1 cup from 3 quarts and 1 pint.
We must convert all the units to the same level of measurement in order to remove these two mixed volume units. We are aware that 2 pints and 2 cups equal 1 quart. In order to subtract the volumes, we can convert the pint and cup units to quarts.
We begin by converting 1 pint to quarts:
Pints equal half quarts.
The next step is to convert 1 cup to quarts:
1/4 pint is equal to one cup.
Hence, the second mixed unit is:
1.75 quarts are equal to 1 quart, 2 pints, and 1 cup (1 + 2(1/2) + 1/4).
We may now take the volumes away:
3 quarts and a pint minus a pint, a cup, and a quart equals 3 + 1/2 minus 1.75 to 2.75 quarts.
This result can be written as a whole number of quarts plus any leftover pints and cups to return it to mixed units. Since a quart is equal to two pints, we can write:
2.75 quarts equal 2 quarts plus a half-quart.
We may convert the remaining 1/2 quart to pints because 2 cups equal 1 pint:
2 pints from a half-quart
The end result is as a result:
1 quart, 2 cups
Therefore, 2 quarts, 1 pint, and 2 cups are the outcome of removing 1 quart, 2 pints, and 1 cup from 3 quarts and 1 pint.
