Answer:

Total Surface Area

= 24 in^2

Step-by-step explanation:

A cube has 6 sides (faces). Each side is a square. The square face (all of them) is a 2 by 2 square. The area of each square face is 2 × 2 = 4 square inches. There 6 faces that are 4 square inches each. The total surface area is all of the 6 sides added together.

TSA = 4+4+4+4+4+4

TSA = 24 square inches

The total surface area is 24 in^2.

Step-by-step explanation:

The percentage of pink is 13%.

There are 28 numbers in total that are odd numbers greater than 500 with no digit being repeated.

First, there are 18 odd numbers with four digits, and all of them are greater than 500. To see that, starting from the end of the number, there are 3 options for the last digit, 3 for the second last, 2 for the second digit, and 1 for the first digit. Multiplying one gets 3*3*2*1=18.

Second, for numbers with 3 digits, in order to be greater than 500, it must start either with 5 or with 6. If it starts with 5, there are 2 options for the last digit and 2 options for the second digit.

Thus, there are 4 different numbers in this case. Finally, if it starts with 6, then there are 3 options for the last digit and 2 options for the second digit. Thus, there are 6 different numbers in this case.

Complete question: How many different odd numbers greater than 500 can be made using some or all of the digits 1,3,5 and 6 with no digit being repeated?

The system of inequalities representing the graph is option A.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

There are two lines drawn on the graph.

Dashed line passes through (0, 3) and (1, 1).

Slope = change in y coordinates / change in x coordinates

          = (1 - 3) / 1 - 0 = -2

Intercept along the y axis is 3.

Equation in slope intercept form is y = -2x + 3.

Solution region of the line does not pass through origin.

At origin 0 = 0 + 3, 0 < 3 is true, but since the solution region of the line does not pass through origin, we take the inequality results as 0 > 3.

So the inequality is y > -2x + 3.

Solid line passes through (0, -1) and (1, 1).

Slope = (1 - -1) / (1 - 0) = 2

Intercept along y axis is -1.

Equation in slope intercept form is y = 2x - 1.

Solution region of the line does not pass through origin.

At (0, 0), 0 = 0 - 1, 0 < -1 is the result of inequality.

Since it is a solid line, inequality will be ≤.

So inequality is y ≤ 2x - 1.

Hence the correct option is A.

A. The coefficient of x^4y^{12} in the expansion of (-4x+2y)^{16} is -8192.

B. The coefficient of x^4y^8z^7 in the expansion of (-4x+2y-1z)^{19} is -134217728.

For the first question, we can use the binomial theorem to expand the expression. The binomial theorem states that

(a+b)^n = C(n,0)a^nb^0 + C(n,1)a^{n-1}b^1 + C(n,2)a^{n-2}b^2 + ... + C(n,n)a^0b^n

Where C(n,k) = n!/(k!(n-k)!)

Applying this to the given expression, we get:

(-4x+2y)^{16} = C(16,0)(-4x)^{16}(2y)^0 + C(16,1)(-4x)^{15}(2y)^1 + C(16,2)(-4x)^{14}(2y)^2 + ... + C(16,16)(-4x)^0(2y)^16

The coefficient of x^4y^{12} is the coefficient of the term -4x^42y^{12} in this expansion, which is

C(16,4)(-4)^42^{12} = C(16,4)(-256)4096 = C(16,4)(-256)*4096 = -8192

For the second question, the same logic can be applied to:

(-4x+2y-1z)^{19} = C(19,0)(-4x)^{19}(2y)^0(-1z)^0 + C(19,1)(-4x)^{18}(2y)^1(-1z)^0 + C(19,2)(-4x)^{17}(2y)^2(-1z)^1 + ... + C(19,19)(-4x)^0(2y)^0(-1z)^19

The coefficient of x^4y^8z^7 is the coefficient of the term -4x^42y^8(-1z)^7 in this expansion, which is C(19,4)(-4)^42^8*(-1)^7 = C(19,4)256256*-1 = -134217728

Let the numbers are: a₁, a₂, a₃.

These three numbers form an arithmetic sequence, which means the differences between 2 consecutive terms are the same.

Hence,

a₃ - a₂ = a₂ - a₁

a₃ = 2a₂ - a₁   ..... (equation 1)

The cost of a slice of pizza is $2.5.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Let x be the price of 1 slice of pizza and y be the price of a drink.

Cost of a bag of chips = 50 cents = $0.5

A family buys 3 slices of pizza, 2 drinks, and one bag of chips for $10.

Another family bought 2 slices of pizza, 4 drinks, and a bag of chips for $9.50.

We have two linear equations,

3x + 2y + 0.5 = 10 or 3x + 2y = 9.5

2x + 4y + 0.5 = 9.5 or 2x + 4y = 9

So we have

3x + 2y = 9.5

2x + 4y = 9

Multiplying throughout the first equation with 2 and subtracting the second equation from the resultant equation, we get

[2(3x + 2y) - (2x + 4y) = (2 × 9.5) - 9

6x - 2x = 10

One real-world application for adding and subtracting polynomials is in the field of electrical engineering, specifically in circuit analysis.

Problem: Design an electrical circuit that combines two input signals and produces an output signal that is the sum of the two input signals.

Solution: The input signals can be represented by two polynomials, say A(x) and B(x), where x represents time. To find the output signal, we need to add the two input polynomials, resulting in a new polynomial C(x) = A(x) + B(x). This polynomial C(x) represents the output signal of the circuit.

To solve the problem, the circuit designer would need to identify the specific forms of the input signals, A(x) and B(x), and then use polynomial addition to find the output signal C(x). Depending on the complexity of the input signals, this could be done by hand or with the help of a computer program.

Once the output signal C(x) has been found, the circuit designer can use this information to select the appropriate components and design the circuit layout to produce the desired output.

i) 64 outcomes.

ii) 6 outcomes.

The combination is composed by four digits, and each digit is independent of other digits, meaning that the Fundamental Counting Theorem is used to obtain the possible number of combinations.

The Theorem states that the total number of combinations is given by the multiplication of the number of outcomes for each digit.

For item i, as repetition is allowed, the first digit assumes a value of 1, hence there is only one possible outcome, while each of the remaining three digits can assume three values, hence the number of combinations is given as follows:

N = 4 x 4 x 4 = 4³ = 64 combinations.

When repetition is not allowed, and the number starts with the number one, we have that:

In option A, P=6 and a=1/8. The base is less than 1 (1/8 < 1) so this function is not an exponential growth function.

In option B, P=6 and a=1. The base is equal to 1, which is not greater than 1, so this function is not an exponential growth function.

In option C, P=1/6 and a=8. The base is greater than 1 (8 > 1) so this function is an exponential growth function.

In option D, P=1/6 and a=1/8. The base is less than 1 (1/8 < 1) so this function is not an exponential growth function.
