I really need help ;-;) pls explain this

The quadratic function graphed is defined as follows:

f(x) = 3(x - 3)(x - 7).

We are given the roots for each function, hence the factor theorem is used to define the functions.

The function is defined as a product of it's linear factors, if x = a is a root, then x - a is a linear factor of the function.

The roots of the function are given as follows:

Hence the linear factors of the function are:

The function then is:

f(x) = a(x - 3)(x - 7)

When x = 8, y = 15, hence the leading coefficient a is obtained as follows:

5a = 15

a = 3.

Hence:

f(x) = 3(x - 3)(x - 7).

Step-by-step explanation:

Answer:

700,000

Step-by-step explanation:

To explain this, we need to know the basics.

If you look at the number 790,390, you should automatically know that you can also write the same number as:

700,000 + 90,000 + 300 + 90

How did we do this?

Because each number in 790,390 has a value.

In fact, we can do this for any number! Like this:

12,345

You can also write the same number like this:

10,000 + 2,000 + 300 + 40 + 5

Back to the original question. If there is a seven in the hundred thousands place, that means that the 9 is equal to 700,000

Examples:

12,345

The 3 in this number stands for 300, since it is in the hundreds place.

678,900

The 7 in this number stands for 70,000 because it is in the ten thousands place

Now you know!

Answer:

Rs 36 600

Step-by-step explanation:

PRT/100

P is the principle

R is the rate of interest

T is the time taken

30 000 * 2 * 11

=660 000/100

= 6600 is the amount of interest charged after the 2 years

now to find the total amount received after the 2 years

= 6600 + 30 000 =36600

Answer:

Sarah's Store

Step-by-step explanation:

Sorry it took a long time.

Answer:

Thor is the best deal.

Step-by-step explanation:

Thor is $10.35, Lemon is $11.73, Patrick is $14.66, and Sarah is $16.63.

For Thor, multiply $1.15(2)=$2.30. Then multiply $1.15(7)=$8.05. Add these together to get $10.35.

For Lemon, multiply 17($1.15)=$19.55. Then subtract by $7.82 to get $11.73.

For Patrick, use the equation we already did 17($1.15) and subtract $4.89 from it to get $14.66.

Last, For Sarah multiply our $19.55 (.15) to find 15% and get 2.934. Then subtract $19.56 - 2.934 to get $16.626. Round to $16.63.

Hope this helped!

Answer:

-19.35

Step-by-step explanation:

   Steps

   7.45−24.45+74.17−76.52

   57.17−76.52

Answer:

Differential equation: [tex]\frac{dA}{dt} = k\cdot A(t)[/tex], [tex]k < 0[/tex], [tex]k = -\frac{1}{\tau}[/tex], [tex]\tau > 0[/tex].

Solution: [tex]A(t) = A_{o}\cdot e^{-\frac{t}{\tau} }[/tex]

Step-by-step explanation:

Let suppose that rate of change of the amount of Carbon-14 atoms are directly proportional to the current amount of Carbon-14 atoms. That is:

[tex]\frac{dA}{dt}\propto A(t)[/tex]

[tex]\frac{dA}{dt} = k\cdot A(t)[/tex]

Where:

[tex]A (t)[/tex] - Amount of Carbon-14 atoms, dimensionless.

[tex]k[/tex] - Proportionality constant, measured in [tex]\frac{1}{yr}[/tex].

[tex]k[/tex] must be negative as death rate is constant and birth rate is zero. ([tex]k< 0[/tex]). Dimensionally, we can rewritte this constant as following:

[tex]k = -\frac{1}{\tau}[/tex]

Where [tex]\tau[/tex] is the time constant ([tex]\tau > 0[/tex]), measured in years.

We can find the solution of the ordinary differential equation by separating each variable:

[tex]\frac{dA}{dt} = -\frac{1}{\tau}\cdot A[/tex]

[tex]\int {\frac{dA}{A} } = -\frac{1}{\tau} \int \, dt[/tex]

[tex]\ln A(t) = -\frac{t}{\tau} + C[/tex]

[tex]A(t) = e^{-\frac{t}{\tau}+C }[/tex]

[tex]A(t) = e^{C}\cdot e^{-\frac{t}{\tau} }[/tex]

[tex]A(t) = A_{o}\cdot e^{-\frac{t}{\tau} }[/tex]

Where [tex]A_{o}[/tex] is the initial amount of atoms of Carbon-14.

Answer: Debit salaries expense 3920

Credit salaries payable 3920

Step-by-step explanation:

Note that the total amount that the company will pay to the employees on Monday, January 6, 2020, is approximately $1,166.69.

Based on the given information, we can calculate the total amount that the company will pay to the employees on Monday, January 6, 2020.

The company has 15 employees, and they earn a total of $2,500 in salaries each working day. Therefore, the daily salary per employee is $2,500 divided by 15, which is approximately $166.67.

From December 31, 2019, to January 6, 2020, there are a total of 7 days, including New Year's Day, which is a paid holiday.

The employees worked the first two days of that week (December 31 and January 1), which means they will be paid for those two days.

On January 6, 2020, the employees will be paid salaries for five full days, which includes the remaining three days of the previous week and the upcoming week.

To calculate the total amount paid on January 6, 2020, we add the salary for the two worked days and the salary for the five full days:

Total amount paid = (Salary per day * 2) + (Salary per day * 5)

= ($166.67 * 2) + ($166.67 * 5)

≈ $333.34 + $833.35

≈ $1,166.69

Hence, the total amount that the company will pay to the employees on Monday, January 6, 2020, is approximately $1,166.69.

Answer:

[tex] y = 8x + 16 [/tex]

[tex] x = 12 [/tex]

Step-by-step explanation:

Given two points on the line (0, 16) and (3, 40), an equation for the line can be written using the slope-intercept line equation which takes the format [tex] y = mx + b [/tex].

Where,

[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

b = y-intercept or the point at which the line cuts the y-axis.

Let's find slope (m) using the slope formula:

Let,

[tex] (0, 16) = (x_1, y_1) [/tex]

[tex] (3, 40) = (x_2, y_2) [/tex]

[tex] slope (m) = \frac{40 - 16}{3 - 0} [/tex]

[tex] slope (m) = \frac{24}{3} [/tex]

[tex] slope (m) = 8 [/tex]

Find b. Substitute the values of x = 0, y = 16, and m = 8 in the slope-intercept formula to find b.

[tex] y = mx + b [/tex]

[tex] 16 = 8(0) + b [/tex]

[tex] 16 = 0 + b [/tex]

[tex] 16 = b [/tex]

[tex] b = 16 [/tex]

Plug in the values of m and b into the slope-intercept formula to get the equation of the line.

[tex] y = mx + b [/tex]

[tex] y = 8x + 16 [/tex]

Let's use the equation to find x when y = 112.

[tex] y = 8x + 16 [/tex]

Substitute y = 112 in the equation

[tex] 112 = 8x + 16 [/tex]

[tex] 112 - 16 = 8x [/tex]

[tex] 96 = 8x [/tex]

Divide both sides by 8

[tex] 12 = x [/tex]

[tex] x = 12 [/tex]

Step-by-step explanation:

There isn't enough information about what y would be if you meant for solving for the value of x. However, to get the equation to solve for x, all you need to do is to isolate the x by itself, which in this case you would need to add 7y to both sides. The answer should be x=7y+8
