Step-by-step explanation:

you can use proportions to convert molecules to moles and then moles to grams.

To convert molecules to moles, use the Avogadro number (6,022 × 10²³ atoms)

The proportion is:

1 : Avogadro number = x : number of molecules

so

1 : 6,022 × 10²³ = x : 4,5 × 10²⁴

solve. x = 7,47 moles

From the moles you can get the grams of SO2. To find grams, first find the mass of SO2.

S = 32,06

O2 = (16×2) = 32

so mass of SO2 is 64,06

Now use the proportion:

mass of SO2 : 1 = moles : x

so

64,06 : 1 = 7,47 : x

solve. x = 0,11 grams

Given

Set x=6; then,

If x=6, y=2

According to the compound interest concept, the total amount he will be paid is  $8,864.73

Compound interest:

The general form of the compound interest is,

A = P(1 + r/n)ⁿˣ

where

A = Accrued amount (principal + interest)

P = Principal amount

r = Annual nominal interest rate as a decimal

R = Annual nominal interest rate as a percent

r = R/100

n = number of compounding periods per unit of time

x = time in decimal years;

Given,

Ryan has an eight–year loan for $6,000. He is being charged an interest rate of 5 percent, compounded annually.

Here we need to find the total amount he will pay.

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)ⁿˣ

A = 6,000.00(1 + 0.05/1)⁽¹⁾⁽⁸⁾

A = 6,000.00(1 + 0.05)⁸

A = $8,864.73

Therefore, the total amount that he will pay is $ 8,864.73

The length of the straight path they must run to get back to the starting line is 4.47 miles.

Displacement [x] of an object is the length of the straight line joining the initial and final position of the object. Mathematically, displacement can be written as-

Δx = x[2] - x[1]

Now -

Δx = vΔt              {[v] is velocity}

So we can write -

vΔt = x[2] - x[1]

Given are the runners at a cross-country meet such that they ran 2 miles to south and then 4 miles to west from the starting line.

We can find the straight path they must run to get back to the starting line using the Pythagoras theorem. The base will be equal to distance ran towards south and height will be equal to the distance ran towards west. The length of the hypotenuse will be equal to that of displacement or the straight path they must run to get back to the starting line. Using Pythagoras theorem -

[h]² = [b]² + [p]²

[h]² = (2 x 2) + (4 x 4)

[h]² = 4 + 16

[h]² = 20

[h] = 4.47 miles

Therefore, the length of the straight path they must run to get back to the starting line is 4.47 miles.

aₙ = 4 × 5⁽ⁿ ⁻ ¹⁾ is the explicit formula for the geometric sequence: 4, 20, 100, 500.

A geometric progression is simply a sequence of non-zero numbers, every term after the first can be determine by multiplying the previous number by a common ratio.

The nth term of a geometric sequence is expressed as;

aₙ = a₁ × r⁽ⁿ ⁻ ¹⁾

Where a₁ is the first term, r is the common ratio and n is the number of terms.

Given the sequence in the question;

4, 20, 100, 500, ...

First determine the common ratio.

r = any term / previous term

r = 20/4

r = 5

Th first term in the sequence is 4.

Plug these into the geometric sequence formula and simply.

aₙ = a₁ × r⁽ⁿ ⁻ ¹⁾

aₙ = 4 × 5⁽ⁿ ⁻ ¹⁾

Therefore, the explicit formula for the sequence is aₙ = 4 × 5⁽ⁿ ⁻ ¹⁾

The product of 6000 and 50 can be found below

We are given a data set and we are asked to write the model that fits the data. We notice that for each step of "x" the values of "y" increase by the same amount. That means that the data follow a linear model, therefore, we will use:

Where:

To determine the slope "m" we will use the following formula:

Where:

Are data points. From the table we choose the following points:

Now, we substitute in the equation for the slope:

Solving the operations:

Therefore, the slope is -7. Substituting in the equation of the line we get:

Now, we substitute one of the points to get the value of "b". We will substitute the value x = -8, y = 47, we get:

Part A:

Given 900 dollars

Interest rate = 4.5%

Value at the end of 5 years

900 × 4.5% × 5 = $226.62

900 + 226.62 = 1,126.62

= 1,126.62 after 5 years

Part B: Given 900 dollars is placed in a saving account

interest rate = 4.5% semiannually (which means twice a year)

We need to find the value after 5 years

Since it's semiannually it's twice a year

5 × 2 = 10

900 × 4.5% (interest rate) × 10

900 × 4.5% × 10 = 510.29

510.29 + 900(intital amount) = 1,410.29

= $1,410.29 after 5 years

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, it is given from the part A of solution :

the linear function that models the situation is C(x) = 75x + 1908

Now, for cost of manufacturing C(x) = 2658 the value of x will be :

C(x) = 75x + 1908

2658 = 75x + 1908

75x = 2658-1908

75x = 750

x = 10

Therefore, the cost of manufacturing C(x) = 2658 in a day is $2658

The way in which the given ordered pairs represent a function is: b. For every x value, there is only one y value - a function.

A function simply refers to a mathematical expression (equation) which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for uniquely mapping an input variable (x-value) to an output variable (y-value).

In this context, we can reasonably infer and logically deduce that these ordered pairs represent a function because it has different input variables (x-values) for different or the same output variables (y-values).
