Sandy collected 10 pounds of apples at an apple orchard. She is determined to
eat 20% of the apples remaining every day after the day she went to the orchard.
Write an exponential function to model this scenario and use it to estimate how
many pounds of apples she has left after 1 week.

Answers

Answer 1

The weight of apple that Sandy has left after one week is 2.1 pounds.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let y represent the number of apple remaining after x days. Sandy collected 10 pounds of apples at an apple orchard and eat 20% daily, hence:

y = 10(1 - 0.2)ˣ

y = 10(0.8)ˣ

After 1 week, x = 7:

y = 10(0.8)⁷ = 2.1 pounds

The weight of apple that Sandy has left after one week is 2.1 pounds.

Triangle ABC is an equilateral triangle. Use the figure to find the value of x

Answers

The value of x in the equilateral triangle is 10

The equilateral triangle's three characteristics are: Equal on all three sides. The three angles are identical. Three symmetry lines may be seen in the figure. Additionally, each inside angle is identical (60 degrees).

A unique isosceles triangle with three equal sides is called an equilateral triangle. The formulas that we take into account most frequently for a triangle are: Dimensions of an equilateral triangle , the equilateral triangle's circumference, Equilateral triangle's height

An equiangular triangle's area can be calculated using the following formula:

If A=√3a2/4, then ABC's perimeter 3a

where a is the triangle's side length.

In equilateral triangle, the sum of the 3 angles are 180°.then the angle of each side is 60°

From the given data,

(7x-10)°=60°

7x=60+10

7x=70, x=10

Hence the value of x is 10

Answers

Given functions f(x) and g(x), we are to put them into a ratio of f(x)/g(x), which simply means that f(x) is divided into g(x).

So, given the operation of division, f(x)/g(x), substitute in both functions.

(f/g)(x)=((Cube root)√3x)/(5x+2)

Remember, these are rational expressions, so they cannot contain 0 in the denominator. Division by 0 creates an irrational value, and we want to keep the expressions rational. Also recall that x-x=0, so we need to figure out what x-value multiplied by 5 and added to 2 would equal 0. To do this:

5x+2=0

x=-2/5.

Plug this x-value back into the denominator to assure it is true:

5(-2/5)+2=0, and therefore, x≠-2/5.

Remember, we can’t divide by 0, and since this is a function, x=-2/5 would equal 0, so x≠-2/5.

Dexter Technology maintains its records using cash-basis accounting. Consider the following:

During the year, the company received cash from customers, $45,000, and paid cash for salaries, $24,500.
At the beginning of the year, customers owe Dexter $1,200. By the end of the year, customers owe $7,000.
At the beginning of the year, Dexter owes salaries of $6,000. At the end of the year, Dexter owes salaries of $3,500.

Answers

Based on the records of Dexter Technology, the net income using the cash-basis is $20,500 and the net income using accrual basis is $28,800.

What is the net income?

Using the cash basis, the net income will be only for transactions that cash has either been received for or paid for:

= Cash from customers - Cash paid for salaries

= 45,000 - 24,500

= $20,500

The net income using accrual caters for the expenses and revenue that happened in a year regardless of when they are paid:

= Revenue - Salaries expense

= (45,000 - 1,200 + 7,000) - (24,500 - 6,000 + 3,500)

Answers

Answer:

commutative property of multiplicationassociative property of additionadditive inverse propertymultiplication property of zero

Step-by-step explanation:

You are asked to identify the real number properties that justify various changes in the way an expression is written.

Properties of numbers

In general, there are associative, commutative, identity, and inverse properties of addition and multiplication. You can use these properties to simplify and rewrite expressions, and to help perform arithmetic.

This is basically a vocabulary question, to see if you know the names associated with the behaviors these properties describe.

Commutative properties

When an operation (such as addition or multiplication) has the commutative property, it means the order of its operands does not matter

  addition: a + b = b + a

  multiplication: a × b = b × a

Associative properties

When an operation has the associative property, it means that grouping of operands does not matter.

  addition: (a + b) + c = a + (b + c)

  multiplication: (ab)c = a(bc)

Identity properties

When an operation is performed using its identity element, the value of the other operand is not changed:

  addition: a + 0 = a

  multiplication: a × 1 = a

Inverse properties

When an operation has an inverse, performing the operation with the inverse produces the identity element.

  addition: a + (-a) = 0

  multiplication: a × (1/a) = 1

Note: these last two properties are used to simplify and solve algebraic expressions. They let you "undo" operations done to variables or expressions.

Questions at hand

You can match the given expressions to the example expressions shown above. The "multiplication property of zero" is also known as the "zero product rule": a product is zero if and only if a factor is zero.

  [tex]\begin{aligned}d\cdot4=4\cdot d\quad&\text{commutative property, multiplication}\\(2+a)+8=2+(a+8)\quad&\text{associative property, addition}\\m+(-m)=0\quad&\text{additive inverse property}\\0\cdot b=0\quad&\text{multiplication property of 0}\end{aligned}[/tex]

WHAT ARE LINEAR EQUATIONS ?

There is only one or two variables in a linear equation. Nothing can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All the dots fall on the same line when the values that, when added together, make a linear equation true are determined and plotted on a coordinate grid.

CALCULATION

let no. of republicans be x

then, no. of democrats is x + 30

total no. of  members given are = 433

  so if we make the equation

           x + x + 30 = 433

          2x = 403

            x = 201 members of republican

        democrats = 201 + 30 = 232

therefore ,  there were total 201 republicans and 232 democrats .

Even if you had a right to stay, how could you live where you are now? You have sold all your country. You have not a piece as large as a blanket to sit down upon. What is to support yourselves, your women, and children? The tract you have ceded will soon be surveyed and sold, and immediately afterwards will be occupied by a white population. You will soon be in a state of starvation. You will commit depredations upon the property of our citizens. You will be resisted, punished, perhaps killed. Now is it not better peaceably to remove to a fine, fertile country, occupied by your own kindred, and where game is yet abundant? The annuities payable to you, and the other stipulations made in your favor, will make your situation comfortable, and will enable you to increase and improve. If, therefore, you had a right to stay where you now are, still every true friend would advise you to remove. But you have no right to stay, and you must go You shall be comfortably taken care of, and kindly treated on the road, and when you arrive in your new country, provisions will be issued to you for a year, so that you can have ample time to provide for your future support.But lest some of your rash young men should forcibly oppose your arrangements for removal, I have ordered a large military force to be sent among you If you listen to the voice of friendship and truth, you will go quietly and voluntarily. But should you listen to the bad birds that are always flying about you, and refuse to move, I have then directed the commanding officer to remove you by force. This will be done. I pray the Great Spirit, therefore, to incline you to do what is right.Your FriendA. Jackson- In what ways was Jackson telling the truth?- In what ways was he not telling the Seminole the truth?
