Answer:

The function f(x)= 16-4x forms an arithmetic sequence when x=1,2,3,...

Step-by-step explanation:

An arithmetic sequence is a sequence of numbers such that the difference between any two consecutive terms is always the same.

The function f(x) = 16 - 4x forms an arithmetic sequence when x = 1, 2, 3, ...

When x = 1, f(x) = 16 - 4(1) = 12

when x = 2, f(x) = 16 - 4(2) = 8

when x = 3, f(x) = 16 - 4(3) = 4

As you can see, the difference between any two consecutive terms is 4, which is the same for all terms, therefore the function f(x) = 16 - 4x forms an arithmetic sequence when x = 1, 2, 3, ...

On the other hand, the function f(x) = 8 (2)^x increases exponentially, so the values obtained would be not part of an arithmetic sequence. The function f(x) = x^2/5 has no common difference between the consecutive terms, so it is not an arithmetic sequence. The function f(x) = 4/x -2 is not an arithmetic sequence either, due to the division of 4 by x and the subtraction of 2.

The value of the sequence aₙ₊₁ is -5.5

The definition of the sequence is given as

8.0, 6.5, 5.0, 3.5, . . .

The above definitions imply that we simply subtract 1.5 from the previous term to get the current term

Using the above as a guide,

So, we have the following representation

aₙ₊₁ = aₙ - 1.5

From the question, we have

aₙ = -4.0

Substitute the known values in the above equation, so, we have the following representation

aₙ₊₁ = -4.0 - 1.5

Evaluate

aₙ₊₁ = -5.5

The unknown value of the given expression is 750.

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given:

Let x represents the square.

And y and z represent the triangle and star, respectively.

So, from the diagram we have,

x + 3y + z = 51   ....(1)

12x + 5z = 234   .....(2)

8x -6x + 3x = 60

That means,

x = 12

So, from the equation (2),

144 + 5z = 234

z = 18

Then y = 7.

Now, the required diagram in the equation form,

z(y+z-x) + x(y + z + z) = n

Jake is not correct because 192.5 is not close to the estimate. The decimal point belongs after the 9.

In Mathematics, a quotient simply refers to a mathematical expression that is typically used for the representation of the division of a number by another number.

Based on Jake's calculations, we can logically deduce that he forgot to place the decimal point in the following expression;

Answer:

The ratio of paper bags to hard bags is 6:2, which can also be written as 6/2 = 3/1. This means that for every 3 units of paper bags, there is 1 unit of hand bags.

If there are 192 bags in total, and the ratio of paper bags to hard bags is 3:1, then there must be 3 + 1 = 4 parts in total. We can find the number of bags in each part by dividing the total number of bags by the number of parts: 192 bags / 4 parts = 48 bags/part.

Since there are 3 parts of paper bags for every 1 part of hard bags, there must be 3 * 48 bags/part = 144 paper bags. Answer: {144}.

Rounding off refers to the process of approximating a number to a nearby value that has a certain number of significant digits or decimal places. For example, rounding the number 3.14159 to two decimal places would give 3.14, and rounding the number 12345 to the nearest thousand would give 12000. Rounding is often used in situations where precise measurements are not necessary or when the precision of a calculation is limited by the available resources.

A real number is a value that can represent a quantity along a continuous number line, such as integers and fractions. Real numbers include both rational numbers, which can be expressed as the ratio of two integers (such as 3/4), and irrational numbers, which cannot be expressed as the ratio of two integers (such as the square root of 2).

Answer:

Step-by-step explanation:

You want to know the mass of a radioactive isotope on the 19th day if it was 1200 g on the first day and decreased 10% per day.

The form of the equation for exponential decay is ...

  m(t) = a·b^(t-n)

where m is the remaining mass, 'a' is the amount on day n, and 'b' is the growth factor, equal to 1 plus the growth rate.

Here, we have a=1200 g on day n=1, and the growth rate is -10%, so ...

  b = 1 -0.10 = 0.90

That means ...

  m(t) = 1200·(0.90^(t -1))

On day 19, the beginning amount is ...

  m(19) = 1200·0.90^18 ≈ 180.1 . . . . grams

Given that there were 12 slices of pizza, if Dwayne ate half (6 slices) and Mark ate a quarter (3 slices) for example, there would be 3 slices left. However, the question doesn't specify how much pizza Mark ate.

This question involves a concept in Mathematics known as fractions. Dwayne and Mark ordered a pepperoni pizza that was cut into 12 slices. If Dwayne ate half of the pizza, he ate 12/2 slices, which equals 6 slices. Since the question does not specify how much pizza Mark ate, we cannot provide the exact number of slices left. However, if for example, Mark ate 1/4 of the pizza, he would have eaten 12/4 slices, which equals 3 slices. Therefore, the number of slices that were left after both of them finished eating, in this example, would be 12 - (6+3) = 3 slices remaining.

Regression modeling for one-variable equations uses the polynomial result x = ax2 + b + c=0. Given that this polynomial has a second order, the First Thesis of Algebra states that there is only one solution. It is possible to find both simple and sophisticated solutions. Four variables make up a "quadratic formula," as the name suggests. This implies that there may only be one squared word.

By solving a linear equation, we will see that lines are parallel only if x = 15.

Ok, so we know that:

Notice that angle 2 is on the third quadrant of the intersection at the top, and angle 4 is on the second quadrant of the intersection below.

The two lines will be parallel only if these two angles are supplementary, this means that the measures add up to 180°.

Then we need to solve this linear equation:

2x + 10 + 4x + 80 = 180

Now we can solve that for x.

2x + 4x + 10 + 80 = 180

Simplifying:

The process of simplifying an expression involves combining like terms and eliminating any unnecessary terms. In the given expression, we have multiple terms that have the same variable and exponent, these are called like terms. Like terms can be combined by adding or subtracting their coefficients.

In this case, we have 3x^2 and -x^2, the x^2 terms have the same exponent and variable so they can be added together by combining their coefficients (3-1) = 2x^2.

3x^2 - x^2 + 4x - 5y^2 - 4y + 2y^2

Similarly, we have -5y^2 and 2y^2, the y^2 terms have the same exponent and variable so they can be added together by combining their coefficients (-5+2) = -3y^2.

The x terms and y terms are separated and not interacting with each other, so we can't combine them. Finally, we have -4y and 4x, they are not like terms and can't be combined.
