In this question the given polynomial is 4x³ + 3x⁷ - 9x + x¹²

If we rewrite it in the descending order of the powers then the polynomial will be

x¹² + 3x⁷ +4x³ + 9x

This polynomial matches with option C.

Option C is the answer.

Answer:

99x +84 ≤ 1,150

Step-by-step explanation:

Her budget is $1,150, this means that the price of all her purchases cannot exceed it. In other words, the sum of all her purchases must be less or equal to 1,150.

To find how many watches she can buy, you need to multiply it by the price of the watches, which is $99, so it will be 99x.

As for the shirts, she spent $84.

So the inequality equation you will need will be the sum of the price of watches and shirts is less than or equal to 1,150.

99x + 84 ≤ 1,150

Answer:

He needs 0.075 lbs of sugar and 4.925 lbs of water.

Step-by-step explanation:

Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.

Note

5 lbs - 100%

x lbs - 1.5%

Write a proportion:

[tex]\dfrac{5}{x}=\dfrac{100}{1.5}[/tex]

Cross multiply:

[tex]100x=5\cdot 1.5\\ \\100x=7.5\\ \\x=\dfrac{7.5}{100}=0.075[/tex]

So, he needs 0.075 lbs of sugar and 5 - 0.075 = 4.925 lbs of water.

Answer: no

Step-by-step explanation:

Linear functions are straight lines and are also written in the form y=mx+b

The linearity of 3[g(x)] = x depends on the form of g(x). If g(x) is linear, such as g(x) = ax, then the equation is linear. Otherwise, if g(x) involves non-linear operations, the overall equation will not represent a linear function.

Whether or not the equation 3[g(x)] = x represents a linear function depends on the form of g(x). If g(x) is a linear function, then the equation represents a linear transformation. If g(x) is nonlinear, then the overall function is not linear.

For example, if g(x) = exp(3x), the relationship is non-linear due to the exponential function. However, if the g(x) function is a simple linear function like g(x) = a₁x, with a constant coefficient, the equation maintains its linearity. In this scenario, the function could even represent a constant multiple of the identity function, where g(x) = x/3.

It is important to note that in the context of mathematics, understanding whether a function is linear involves recognizing if it can be written in the form of g(x) = mx + b, where m and b are constants, and the function results in a straight line on a graph.

Answer:

Dimetri says that a function that is made of terms

where the variable is raised only to an odd power

will be an odd function. Do you agree with

Dimetri?

Step-by-step explanation:

If g is an odd function and f is an odd function then g ◦ f is odd.

g ◦ f (x) = g (f (x)) = g (−f (−x)) = −g (- (- f (−x))) = −g (f (−x)) = - g ◦ f (−x)

The answer is: No, I am not agree with Dimetri, statement is false because there are so many counterexamples.

Answer:

Sample Response: He is correct only if there is no constant term. −x to an odd power is −x, so the signs will change on the terms with the variable but not on the constant term.

{19, 29, ... , 79, 89}

Step-by-step explanation:

Multiples of 10 are {10, 20, 30, 40, ... , 90}

Numbers which are each 1 less than these multiples of 10 would be:

                               {9, 19, 29, ... , 79, 89}.

Note that the last number, 89, is less than 91.

We must omit 9 from this set, since 9 is not a 2-digit number.  Then our final list is {19, 29, ... , 79, 89}.

Answer:

The numbers are 19,29,39,49,59,69,79,89

Step-by-step explanation:

2 digit numbers starts from 10 and ends on 99.

2 digit numbers less than 91 starts from 10 and ends at 90.

2 digit numbers less than 91 and multiple of 10 are 10,20,30,40,50,60,70,80,90.

2 digit numbers less than 91 and which are 1 less than a multiple of 10 are 19,29,39,49,59,69,79,89.

Final answer:

A base number in mathematics is the number raised to a power, where in scientific notation it is always 10, whereas in economic terms, a base year is a reference year for economic measurements.

Explanation:

The definition of a base number in mathematics generally refers to the number that is being raised to a certain power. In the context of scientific notation, the base number is always 10. This is used to succinctly represent very large or very small numbers in the form N x 10^n, where N is a number greater than or equal to 1 and less than 10, and n is a positive or negative integer; for example, 10^0 = 1. However, the concept of a base extends beyond just the number 10; any number can act as a base in different mathematical contexts.

When discussing numbers in a positional numeral system, the base determines the value of each digit in the number and how those digits are combined to represent the overall number. For instance, in the base-10 system, the digits 0 through 9 are used, and the position of each digit indicates how many multiples of powers of 10 it represents. Finally, in the context of economic indexes, a base year is a reference year against which economic growth or inflation is measured.

The volume of the sand is approximately 0.015605 m3

To solve the problem, and find the volume of the sand that Zed purchased, we need to use the formula to calculate the density and isolate the volume from it.

So, solving we have:

[tex]density=\frac{mass}{volume}[/tex]

From the statement we know that:

The mass of the sand is 25 kg

The density of the dry sand is 1,602 kg/m3

So, substituting and solving we have:

[tex]density=\frac{mass}{volume}\\\\volume=\frac{mass}{density}\\\\volume=\frac{25kg}{1,602\frac{kg}{m^{3}}}=0.015605m^{3}[/tex]

Hence, the volume of the sand is approximately 0.015605 m3

Step-by-step explanation:

5(x - 6) = 2(x + 3)

Distribute

5x - 30 = 2x + 6

Put like terms on each side by subtracting both sides by -2x and adding 30 on each side

3x = 36

Simplify

3x/3 = 36/3

x = 36/3

x = 12

Plug is back in to check

5(12) - 30 = 2(12) + 6

60 - 30 = 24 + 6

30 = 30

Answer:

x=12

Step-by-step explanation:

5(x-6) = 2(x+3)

Distribute

5x-30 = 2x+6

Subtract 2x from each side

5x-2x -30 = 2x-2x+6

3x-30 =6

Add 30 to each side

3x-30+30 = 6+30

3x=36

Divide each side by 3

3x/3 = 36/3

Answer:

B

Step-by-step explanation:

And arithmetic sequence is a sequence in which the difference between each of the numbers are constant.

It is not A, because the difference between 3 and 9 is positive 6, and the difference between 9 and 81 is positive 72.

It is not C, because the difference between 4 and 1 is -3, and the difference between 1 and 4 is positive 3.

It is not D, because the difference between 2 and -2 is -4, and the difference between -2 and 2 is positive 4.

And it is B because the numbers maintain a constant difference between each other, which is -3.

Answer:

B

Step-by-step explanation:

An arithmetic sequence has a common difference (d) between consecutive terms.

The only sequence with a common difference is B

1 = 4 = - 3

- 2 - 1 = - 3

- 5 - (- 2) = - 5 + 2 = - 3

For this case we have the following equation:

[tex]-2 (x + 5) = - 2 (x-2) +5[/tex]

We apply distributive property to the terms within parentheses:

[tex]-2x-10 = -2x + 4 + 5[/tex]

We add similar terms to the right side of the equation:

[tex]-2x-10 = -2x + 9[/tex]

We add 2x to both sides of the equation:

[tex]-10 = 9[/tex]

Equality is not fulfilled, so the equation has no solution.

Answer:

It has no solution

Answer: Yuto's equation has no solution.

Step-by-step explanation:

To find the solution  to Yuto’s equation, you need to solve for the variable "x":

Apply Distributive property:

[tex]-2(x+5)=-2(x-2)+5\\\\-2x-10=-2x+4+5\\\\-2x-10=-2x+9[/tex]

Add [tex]2x[/tex] to both sides of  the equation:

[tex]-2x-10+2x=-2x+9+2x\\\\0x-10=9\\\\-10=9\ (False)[/tex]

Therefore, the equation has no solution.

Answer:

x=7

Step-by-step explanation:

The other angle is equivalent to 45 degrees. According to the 45-45-90 triangle theorem, the hypotenuse is a times the square root of 2 and the legs are equivalent to a. In this scenario a is equivalent to 7. X is another leg and therefore is also 7.

[tex]\bf (-3yz)(-3yz)(-3yz)(-3yz)\implies (-3yz)^1(-3yz)^1(-3yz)^1(-3yz)^1 \\\\\\ (-3yz)^{1+1+1+1}\implies (-3yz)^4\implies (-3)^4 y^4 z^4\implies 81y^4 z^4[/tex]

The expression (-3yz) (-3yz) (-3yz) (-3yz) is  (-3yz) ⁴

  ⇒(-3yz)¹ (-3yz)¹ (-3yz)¹ (-3yz)¹=(-3yz)¹⁺¹⁺¹⁺¹

   ⇒ (-3yz)¹ (-3yz)¹ (-3yz)¹ (-3yz)¹ = (-3yz)⁴
