(X-7)(x-7) multiply the binomials

Answers

Answer 1

The product of given two binomials which are (x-7)(x-7) is equal to x² - 14x + 49.

To multiply the binomials (x-7)(x-7), we use the distributive property of multiplication, which states that:

(a + b)(c + d) = ac + ad + bc + bd

Using this property, we can expand the expression as follows:

(x-7)(x-7) = x(x-7) - 7(x-7)

= x² - 7x - 7x + 49

= x² - 14x + 49

The distributive property of multiplication is a mathematical rule that states that when a number is multiplied by the sum of two or more numbers, it is equivalent to multiplying the number by each of the addends and then adding the products.

653.3 bacteria

Step-by-step explanation:

A continuously growing population of bacteria is modeled by the function:

[tex]P(t) = P_0 \cdot e^{rt}[/tex]

where:

[tex]P(t)[/tex] is the population after [tex]t[/tex] time periods[tex]P_0[/tex] is the initial population[tex]r[/tex] is the relative rate of growth

In this problem, we are given the following values:

[tex]P_0 = 484 \text{ bacteria}[/tex][tex]r = 15\% = 0.15[/tex][tex]t = 2[/tex]

We can plug these into the function to solve for [tex]P(2)[/tex].

[tex]P(t) = P_0 \cdot e^{rt}[/tex]

[tex]P(2) = 484 \cdot e^{(0.15 \, \cdot \, 2)}[/tex]

[tex]P(2) = 484 \cdot e^{0.3}[/tex]

Finally, the right side of this equation can be evaluated using a calculator to solve for the population of the bacteria after 2 hours.

Identify a situation that would fit into this scenario and explain how would you organize this calculation to solve it without a calculator. Assume a 5% sales tax rate. For full credit, you will need the cost of the it, an explanation of how you would calculate the sales tax and the total cost.

Answers

You would add the sales tax amount to the cost of the meal to get the total cost. In this case, the sales tax amount is $1, so the total cost would be $26.

One situation that would fit into this scenario is calculating the total cost of a meal at a restaurant that costs $25. Firstly, to calculate the sales tax, you would need to convert the percentage of sales tax into a decimal.

In this case, the sales tax rate is 5%, so you would convert it to 0.05.Next, you would multiply the cost of the meal by the sales tax rate to calculate the sales tax amount.

To do this calculation without a calculator, you can use mental math or estimation techniques.For example, you could estimate 5% of $25 by breaking the 5% into a 1% and 4% calculation.

To calculate 1%, you would simply move the decimal point two places to the left, which gives you $0.25. Then, to calculate 4%, you could multiply $0.25 by 4, which equals $1.

100 Points! Algebra question. Photo attached. Find the amplitude, if it exists, the period, phase shift, and vertical shift of the function. Then graph the function. Thank you!

Answers

For the function y = 3sin[2(θ-90°)] + 2, the amplitude is 3, the period is π, the phase shift is -45° and the vertical shift is 2 units up.

The amplitude of a sine function represents the maximum displacement from the midline.

The coefficient in front of the sine function is 3, so the amplitude is 3.

The period of a sine function is the length of one complete cycle. It can be calculated using the formula T = 2π/b, where b is the coefficient of θ inside the sine function brackets.

Here, b = 2, so the period is T = 2π/2 = π.

The phase shift of a sine function indicates a horizontal shift to the left or right.

In this case, c = 90°, so the phase shift is θ = 0° - 90°/2 = -45°.

The vertical shift indicates a shift up or down on the y-axis.

The constant term outside the sine function is 2, so the vertical shift is 2 units up.

Answers

Mrs. Bright has worked for 8 years, and Mr. Oswald has already worked for 24 years, which is more than Twice the number of years Mrs. Bright has worked.

The number of years Mrs. Bright has worked for the company. We know that Mr. Oswald has been in the company for 24 years, which is three times the number of years Mrs. Bright has worked.

So, Mrs. Bright has worked for 24 / 3 = 8 years in the company.

Now, let's find the number of years Mr. Oswald needs to work for the company to make it twice the number of years Mrs. Bright has worked.

Twice the number of years Mrs. Bright has worked is 2 * 8 = 16 years.

Since Mr. Oswald is already employed for 24 years, we need to find the additional years he needs to work to reach 16 more years.

16 more years - 24 years = -8 years.

The result of -8 years indicates that Mr. Oswald has already worked for more than twice the number of years Mrs. Bright has worked. Therefore, it is not possible for Mr. Oswald to work for more years in order to make it twice the number of years Mrs. Bright has worked.

x+147=180

x=180-147

x=33°

Hi, I can't tell if there's a little square drawn in red to indicate that there's a right angle in the middle. There's some squiggly lines and so it's kind of hard to tell.

I am going to assume that there is. Let me know if there isn't.

The sum of these 3 angles would be 180 degrees.


As an equation, 57 + 90 + x = 180

147 + x = 180

x = 33 degrees.

a square pyramid sitting on its base. The sides are 8cm, 14cm, and 14cm. whats the surface area of the pyramid in square centimeters?​

Answers

The surface area of the square pyramid is 224 square centimeters.

Since the base of the square pyramid is a square, all sides are equal in length.

Let's call the length of one side of the square base "s".

Then the surface area of the pyramid can be found using the formula:

Surface area = Area of base + Area of four triangles

The area of the base is just s², and the height of each triangle can be found using the Pythagorean theorem.

Let's call the height "h". Then:

h² = 14² - (s/2)² (using the longer side of the triangle as the hypotenuse)

h² = 196 - (s²/4)

Now, we need to find the surface area in terms of "s" and simplify:

Surface area = s² + 4(1/2)(s)(h)

Surface area = s² + 2sh

Surface area = s² + 2s√196 - s²/4))

Surface area = s²+ 2s√(784 - s²))/2

Surface area = s² + s√(784 - s²))

We are given that one side of the square base is 8cm, so:

Surface area = 8² + 8√784 - 8²

Surface area = 64 + 8√400

Surface area = 64 + 8(20)

Surface area = 224

Therefore, the surface area of the square pyramid is 224 square centimeters.

On January 1 2019, a company reported assets of $1500000 and liabilities of $700000. During 2019, assets decreased by $100,000 and stockholders equity decreased $200,000. What is the amount of liabilities at December 31 2019? Enter your answer to the nearest whole number

Answers

The amount of liabilities at December 31, 2019, is $900,000.

To determine the amount of liabilities at December 31, 2019, we can use the accounting equation:

Assets = Liabilities + Stockholders' Equity

Given that the company reported assets of $1,500,000 and liabilities of $700,000 on January 1, 2019, we can set up the equation as follows:

$1,500,000 = $700,000 + Stockholders' Equity

During 2019, assets decreased by $100,000, so the new value of assets at December 31, 2019, would be $1,500,000 - $100,000 = $1,400,000.

Stockholders' equity decreased by $200,000, so the new value of stockholders' equity at December 31, 2019, would be $700,000 - $200,000 = $500,000.

Now we can substitute these values into the accounting equation to solve for liabilities:

$1,400,000 = Liabilities + $500,000

Rearranging the equation, we find:

Liabilities = $1,400,000 - $500,000

Liabilities = $900,000

Therefore, the amount of liabilities at December 31, 2019, is $900,000.

a is the first term (the height of the smallest domino, 4.00 cm),

r is the common ratio (the growth rate, 1.12), and

n is the term number (for domino #7, n = 7 + 1 = 8, because the sequence starts with domino #0).

Let's plug these values into the formula:

[tex]a_8 = 4.00 cm * (1.12)^7[/tex]

(Note that we're using 7, not 8, because the first domino is #0, not #1.)

Danielle Stevenson receives a commission of 6.5% for selling a $160,000 house. One-half of the commission goes to the broker, and one-half of the remainder to another salesperson. Stevenson receives the rest. Find the amount she receives.

Answers

Answer:

Danielle Stevenson receives $2,600 from selling the $160,000 house.

Step-by-step explanation:

To find the amount Danielle Stevenson receives from selling the house, we'll follow these steps:

Calculate the commission earned by Danielle Stevenson: Commission = 6.5% * $160,000.

Commission = 0.065 * $160,000 = $10,400.

Determine the broker's share: Broker Share = 0.5 * Commission.

Broker Share = 0.5 * $10,400 = $5,200.

Calculate the remaining amount after the broker's share: Remaining Amount = Commission - Broker Share.

Remaining Amount = $10,400 - $5,200 = $5,200.

Determine the salesperson's share: Salesperson Share = 0.5 * Remaining Amount.

Salesperson Share = 0.5 * $5,200 = $2,600.

Finally, calculate the amount Danielle Stevenson receives, which is the remaining portion after the broker and salesperson's shares: Amount Danielle Receives = Remaining Amount - Salesperson Share.

Amount Danielle Receives = $5,200 - $2,600 = $2,600.

Therefore, Danielle Stevenson receives $2,600 from selling the $160,000 house.

Answers

The minimum number of monthly checks Regina needs to write for the first account to be a better option is 21 or more. Answer C. 21 is one of the suggested choices.

To solve this problem

On the basis of the quantity of checks written, we can compare the overall costs of the two accounts.

Let's calculate the total cost for each account based on the given information:

First Account:

Monthly fee: $12

Per-check fee: $0.10

Total cost = Monthly fee + (Per-check fee * Number of checks)

Second Account:

Monthly fee: $9

Per-check fee: $0.25

Total cost = Monthly fee + (Per-check fee * Number of checks)

We must determine the point at which the first account's total cost is less than the second account's total cost. Let's construct the formula:

$12 + ($0.10 * Number of checks) < $9 + ($0.25 * Number of checks)

Simplifying the equation

$12 - $9 < ($0.25 - $0.10) * Number of checks

$3 < $0.15 * Number of checks

Dividing both sides by $0.15:

$3 / $0.15 < Number of checks

20 < Number of checks

Therefore, the minimum number of monthly checks Regina needs to write for the first account to be a better option is 21 or more. Answer C. 21 is one of the suggested choices.

Can someone help me? Find the sum of the first 24 terms of the arithmetic series if the first term is 3 and the common difference is 3.

Answers

The sum of the 24 terms of the arithmetic series is 900

How to solve:

To find the sum of an arithmetic series, we can use the formular:

Sn = (n/2)(2a + (n-1)d)

Where;

Sn is the series sum, n is the number of terms, a is the first term, and d is the common difference.

The first term (a) in this scenario is 3, and the common difference (d) is 3. With n equal to 24, we want to find the sum of the first 24 terms.

When the values are entered into the formula, we get:

The sum of the first 24 terms of the arithmetic series is 900 because;

S24 = (24/2)(2(3) + (24-1)(3))

= 12(6 + 23(3))

= 12(6 + 69)

= 12(75)

= 900.

Write a sine function that has a midline of y=4, an amplitude of 2, a period of π, and a horizontal shift of π/4 to the right.

Answers

The sine function with a midline of y=4, an amplitude of 2, a period of π, and a horizontal shift of π/4 to the right is y = 2sin(2(x - π/4)) + 4.

To write a sine function with the given properties, we can use the general form of a sine function: y = A * sin(B(x - C)) + D, where A represents the amplitude, B represents the frequency (or inverse of the period), C represents the horizontal shift, and D represents the vertical shift (or midline).

In this case:

The midline is y = 4, so D = 4.

The amplitude is 2, so A = 2.

The period is π, so the frequency is B = 2π/π = 2.

The horizontal shift is π/4 to the right, so C = -π/4.

Plugging these values into the general form, we get the sine function:

y = 2 * sin(2(x - (-π/4))) + 4

Simplifying further:

y = 2 * sin(2(x + π/4)) + 4

Therefore, the sine function with a midline of y = 4, an amplitude of 2, a period of π, and a horizontal shift of π/4 to the right is y = 2 * sin(2(x + π/4)) + 4.

here is my algebra 13 homework, can someone please help me fast! Quick!!

Answers

The function h(x) = (2ˣ) + 1 does not have an x intercept.

A function has an x-intercept when the value of the function is equal to zero at some point on the x-axis.

(a) f(x) = -x + 2 is a linear function with a negative slope (-1) and a y-intercept of 2.

To find the x-intercept, we set f(x) equal to zero and solve for x:

0 = -x + 2

x = 2

Therefore, the function f(x) has an x-intercept at (2, 0).

(b) g(x) = -(x²) is a quadratic function that opens downward and has a vertex at (0, 0).

To find the x-intercept, we set g(x) equal to zero and solve for x:

0 = -(x²)

x²= 0

x = 0

Therefore, the function g(x) has an x-intercept at (0, 0).

(c) h(x) = (2ˣ) + 1 is an exponential function

To find the x-intercept, we set h(x) equal to zero and solve for x:

0 = (2ˣ) + 1

-1 = 2ˣ

However, there is no real value of x that satisfies this equation.

h(x) = (2ˣ) + 1 has no x intercept.

The equation for the distance of the point (x, y), from the center of the circle is; (x - 4)² + (x - 2)² = 5²

What is the general form of the equation of a circle?

The general form of the equation of a circle with center (h, k) is; (x - h)² + (y - k)² = a², where the radius of the circle is; a

The radius of a circle is the distance from the center to a point (x, y) on the circumference, therefore, the equation for the distance of the point (x, y) from the center of the circle, is equivalent to the equation for a circle, where the distance of the point (x, y) from the center is the radius.

The coordinates of the center of the circle, (h, k) = (4, 2)

The radius of the circle, r = a = 5

The equation for the distance (x, y) from the center, which radius of the circle, with center (4, 2), is therefore;

Equation of a circle; (x - h)² + (y - k)² = a²

Equation from the center; (x - 4)² + (y - 2)² = 5²
