5 people are evenly sharing 12 kilograms of apples how many kilograms of apples should each person get
Answer:
2.4 kilograms
Step-by-step explanation:
Given: 5 people are evenly sharing 12 kilograms of apples
To find: quantity of apples that each person should get
Solution:
Use the unitary method to get the required answer.
Under unitary method, if the value of multiple items is given to us, divide the total value by the number of items to obtain the value of one item.
Quantity of apples for 5 people = 12 kilograms
Quantity of apples for 1 person = \(\frac{12}{5} =2.4\) kilograms
So, each person should get 2.4 kilograms of apples.
Answer:
12/5 or 2 2/5
Step-by-step explanation:
We need to divide the 12 kilograms of apples by the 5 people sharing them, or 125
12 ÷ 5 = 12/5
12/5 = 5/5 + 5/5 + 2/5
= 1 + 1 + 2/5
= 2 2/5
Each person should get 12/5, or 2 2/5, kilograms of apple

Which of the following statements are true?
According to the given graph the correct option that justify it to follow horizontal asymptote concept is option A, C and D.
Define graph property:
In mathematics, a graph is a set of points, called vertices or nodes, that are connected by lines or curves, called edges or arcs. Graphs are used to represent mathematical relationships between objects, data, or concepts. They are a fundamental tool in many fields, including computer science, economics, engineering, social sciences, and more.
Graphs can be represented in a variety of ways, such as a drawing on a piece of paper or a computer screen, or as a mathematical abstraction. Graphs can be directed or undirected, weighted or unweighted, simple or multigraphs, and can have various structures, such as trees, cycles, or complete graphs. They are often used to model networks, such as transportation systems, social networks, or the internet.
What about asymptote?
In mathematics, an asymptote is a straight or curved line that a curve approaches but never touches. In other words, as the curve moves along the x and/or y axis, it gets closer and closer to the asymptote, but never intersects it. Asymptotes are often found in functions that have horizontal or vertical limits that approach infinity or negative infinity.
There are several types of asymptotes, including horizontal, vertical, and slant asymptotes. A horizontal asymptote is a line that the curve approaches as x tends to infinity or negative infinity. A vertical asymptote is a vertical line that the curve approaches as x approaches a certain value, but does not cross. A slant asymptote is a diagonal line that the curve approaches as x tends to infinity or negative infinity, and the degree of the polynomial in the numerator is one more than the degree of the polynomial in the denominator.
According to the given information:
According to the graph f(x) and g(x) both have a horizontal asymptote so, both graphs are exponential functions and they do not through(0,1)
so, both graphs have been shifted and flipped

A statement that describes the result of running the code segment is: the number 10 is displayed
The correct answer is an option (B)
In this question, we have been given the program code.
We need to select a correct statement that describes the result of running the code segment.
Consider the given code.
Start by setting n and sum to 0.
Add the value of n to sum. The first time, the value of n is 0, so sum remains 0.
Increment n by 1, so now the value of n is 1.
The Boolean condition (n = 5) is still false, so the loop will run again. Add 1 to sum (which is now 1), and then increment n (so n is now 2).
Repeat this three more times (while the value of n = 2, 3, and 4)
Increment n, so the value of n is now 5. Now the Boolean condition is true, so the loop stops.

The diagram shows triangle ABC. ABC and BED are straight lines. AB = 12.2cm, CD = 5.8cm, BE:ED = 3:1, Angle ADB = 90°, Angle ABD = 38°.
Work out the size of angle DCE, correct to 1 decimal place. SHOW ALL WORKING IN TEXT FORM, NO IMAGES.
The measure of angle DCE in this problem is given as follows:
m < DCE = 22.5º.
How to obtain the measure of angle DCE?The triangles in this problem are right triangles, meaning that the trigonometric ratios are used to find the measures.
The three trigonometric ratios are given as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.The segment DB is adjacent to angle of 38º, while the hypotenuse is of 12.2 cm, hence the length of segment DB is calculated as follows:
cos(38º) = DB/12.2
DB = 12.2 x cosine of 38 degrees
DB = 9.6 cm.
BE:ED = 3:1, means that segment DE is one-fourth of segment DB, and thus it's length is given as follows:
DE = 1/4 x 9.6
DE = 2.4 cm.
Then for the angle DCE, we have that the opposite side is of 2.4 cm while the adjacent side is of 5.8 cm, hence the tangent is used to find it's measure, as follows:
tan(x) = 2.4/5.8
x = arctan(2.4/5.8)
x = 22.5º
m < DCE = 22.5º.

How much would you have to deposit today to accumulate the same amount of money that $75 monthly payments at a rate of 3.5% compounding monthly for 10 years in an annuity would
earn?
Round to 2 decimal places and do not include the $
symbol.
Answer:
To calculate how much you would have to deposit today to accumulate the same amount of money that $75 monthly payments at a rate of 3.5% compounding monthly for 10 years in an annuity would earn, we can use the formula for the present value of an annuity due:
PV = PMT × ((1 - (1 + r/n)^(-n×t)) / (r/n)) × (1 + r/n)
where:
- PV is the present value of the annuity due (the amount you would have to deposit today)
- PMT is the monthly payment ($75)
- r is the annual interest rate (3.5%)
- n is the number of times interest is compounded per year (12 for monthly compounding)
- t is the number of years (10)
PV = 75 × ((1 - (1 + 0.035/12)^(-12×10)) / (0.035/12)) × (1 + 0.035/12) = **$7,360.47**
Therefore, you would have to deposit **$7,360.47** today to accumulate the same amount of money that $75 monthly payments at a rate of 3.5% compounding monthly for 10 years in an annuity would earn.

Find the balance earned on an account that has $60,000 deposited for 6 years at 1.125% interest compounded continuously? Please help
Answer:
The balance of the account is $64,190.
Step-by-step explanation:
The amount of money after t years of continous compounding is given by the following equation:
\(P(t) = P(0)e^{rt}\)
In which P(0) is the initial deposit and r is the interest rate, as a decimal.
$60,000 deposited for 6 years at 1.125% interest compounded continuously.
This means that \(P = 60000, r = 0.01125, t = 6\)
So
\(P(6) = 60000e^{0.01125*6} = 64190\)
The balance of the account is $64,190.
Given P = x^0.3 y^0.7 is the chicken lay eggs production function, where P is the number of eggs lay, x is the number of workers and y is the daily operating budget.
a) dy/dx
b) Evaluate this derivative at x = 30 and y = 10,000 and interpret the answer.
Answer:
Part A)
\(\displaystyle \frac{dy}{dx}=-\frac{3}{7}P^\frac{10}{7}x^{-\frac{10}{7}}\)
Part B)
The daily operating cost decreases by about $143 per extra worker.
Step-by-step explanation:
We are given the equation:
\(\displaystyle P=x^{\frac{3}{10}}y^{\frac{7}{10}}\)
Where P is the number of eggs laid, x is the number of workers, and y is the daily operating budget (assuming in US dollars $).
A)
We want to find dy/dx.
So, let’s find our equation in terms of x. We can raise both sides to 10/7. Hence:
\(\displaystyle P^\frac{10}{7}=\Big(x^\frac{3}{10}y^\frac{7}{10}\Big)^\frac{10}{7}\)
Simplify:
\(\displaystyle P^\frac{10}{7}=x^\frac{3}{7}y\)
Divide both sides by the x term to acquire:
\(\displaystyle y=P^\frac{10}{7}x^{-\frac{3}{7}}\)
Take the derivative of both sides with respect to x:
\(\displaystyle \frac{dy}{dx}=\frac{d}{dx}\Big[P^\frac{10}{7}x^{-\frac{3}{7}}\Big]\)
Apply power rule. Note that P is simply a constant. Hence:
\(\displaystyle \frac{dy}{dx}=P^\frac{10}{7}(-\frac{3}{7})(x^{-\frac{10}{7}})\)
Simplify. Hence, our derivative is:
\(\displaystyle \frac{dy}{dx}=-\frac{3}{7}P^\frac{10}{7}x^{-\frac{10}{7}}\)
Part B)
We want to evaluate the derivative when x is 30 and when y is $10,000.
First, we will need to find P. Our original equations tells us that:
\(P=x^{0.3}y^{0.7}\)
Hence, at x = 30 and at y = 10,000, P is:
\(P=(30)^{0.3}(10000)^{0.7}\)
Therefore, for our derivative, we will have:
\(\displaystyle \frac{dy}{dx}=-\frac{3}{7}\Big(30^{0.3}(10000^{0.7})\Big)^\frac{10}{7}\Big(30^{-\frac{10}{7}}\Big)\)
Use a calculator. So:
\(\displaystyle \frac{dy}{dx}=-\frac{1000}{7}=-142.857142...\approx-143\)
Our derivative is given by dy/dx. So, it represents the change in the daily operating cost over the change in the number of workers.
So, when there are 30 workers with a daily operating cost of $10,000 producing a total of about 1750 eggs, the daily operating cost decreases by about $143 per extra worker.
For f(x) = 2x + 1 and g(x) = x^2 - 7, find (f-g)(x)

Step-by-step explanation:
We are given the two functions:
\(\displaystyle f(x) = 2x + 1 \text{ and } g(x) = x^2 - 7\)
And we want to find:
\(\displaystyle (f- g)(x)\)
Recall that:
\(\displaystyle (f - g)(x) = f(x) - g(x)\)
Substitute and simplify:
\(\displaystyle \begin{aligned}(f-g)(x) &= f(x) - g(x) \\ \\ &= (2x + 1) - (x^2 - 7) \\ \\ &= (2x +1 )+ (-x^2 + 7) \\ \\ &= -x^2 +2x + 8\end{aligned}\)

Which of the following could be the function of a real variable x whose graph is shown below?
ANSWER
Option D
EXPLANATION
We want to find the equation that could be a possible function of x of the given graph.
To solve this, we have to apply the knowledge of the roots of an equation/function.
We know that for an equation:
\((x-a)(x-b)=0\)The roots of the equation are a and b.
For a graph, the roots of the graph (for a quadratic graph) are the x values of the two points where the graph touches the x axis.
From the given graphs, we see that the two roots of the graph lie on the positive x axis. This means that the roots of the function must be positive.
Therefore, from the function above, a and b must be positive values.
The only options that provide us with this possibility is option D where a and b are 3 and 7 respectively.
Therefore, the correct answer is Option D.
