Answer:

  C  The cost of living will increase by approximately 5% each year

Step-by-step explanation:

If we assume your function is ...

  [tex]f(x)=34000(1.05)^x\qquad\text{x is years}[/tex]

Then the growth factor 1.05 represents a growth rate of 1.05 -1 = .05 = 5% per year. The positive growth rate means the cost of living is increasing.

Noah's cost of living is increasing about 5% per year.

Answer:

1st box

3rd choice

Step-by-step explanation:

Those are the only choices that are symmetric about the y-axis

The 2nd choice isn't because it doesn't reflect over the y-axis

A graph is a way to represent a lot of data in a visual format. The functions that are symmetric about the y-axis are graphs 1 and graph 3.

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

The y-axis is the vertical axis of the graph, therefore, the functions that are symmetric about the y-axis are the graph of function 1 and the graph of function 3.

Hence, the functions that are symmetric about the y-axis are graphs 1 and graph 3.

Answer:

A = 3x^2 - 2x - 1

Step-by-step explanation:

3x times x equals 3x^2

(3x times - 1) + (x times 1) = -2x

1 times -1 = -1

put the partial products together, you get the above answer.

Answer:

Step-by-step explanation:

The easiest and most proper way to approach this task is to combine like terms inside parentheses:  (24x + 7 – 12x) => (12x + 7).

Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7).  This is an acceptable answer.  There is the option of carrying out the multiplication, which results in

3x + 7/4, which is another acceptable answer.

Answer:

Cost of 1 bushes = a = $9

Cost of 1 tree = b = $73.5

Step-by-step explanation:

Given:

13 bushes and 4 trees cost = $411

Missing;

6 bushes and 2 trees cost = $201

Find:

Value of bushes and tree

Computation:

Cost of 1 bushes = a

Cost of 1 tree = b

So,

13a + 4b = 411 ...........eq1

6a + 2b = 201 ................eq2

From Eq1 and Eq2

Cost of 1 bushes = a = $9

From eq 1

13a + 4b = 411

13(9) + 4b = 411

Cost of 1 tree = b = $73.5

Answer:

10.3

Step-by-step explanation:

The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.

[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]                            

We find the square root of both sides to find the value of c.

10.295 ≈ c

Rounded to the nearest tenth, c ≈ 10.3. The answer is 10.3

(-5s¹²)/ (2t³³) is the Simplified form of the Given equation.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given an equation [tex](\frac{5s^{2}t^{-7} }{-2s^{-2}t^{4} })^{3}[/tex]

Simplifying using PEMDAS

First, we will solve the power

=> (-5/2 s²⁺² t⁻⁷⁻⁴)³

=> (-5/2 s⁴ t⁻¹¹)³

=> (-5s¹²)/ (2t³³)

Therefore, the Simplified notation of the Given equation is (-5s¹²)/ (2t³³).

Answer:

Step-by-step explanation:

495. I just took it 100%

The measure is of an angle that is coterminal with a 135° angle is,

⇒ 495°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

The angle is,

⇒ 135°

Now, To find the coterminal angle add 360 to the given angle as;

⇒ 360 + 135

⇒ 495°

Thus, We get;

Coterminal angle = 495 degrees

Answer:

7

Step-by-step explanation:

Note the values on the right are 7 times the corresponding value on the left side, that is

15 × 7 = 105

12 × 7 = 84

4 × 7 = 28

Then

1 × 7 = 7 ← required value

Answer:

7 or B

Step-by-step explanation:

28/4=7

12*7=84

7 is the number you multiply the first row by to get tbe second row. 1*7=7

5 + 8 + 1 + 2 + 10  =  26 (divided by) 5 = 5.2

The mean and the standard deviation of the data set is 5.2 and 3.429.

The arithmetic mean is the average of a sum of numbers that shows the centre tendency of the numbers' position. It is frequently used as a parameter in statistical distributions or as a result of an experiment or a survey to summarise the findings.

We have,

Data:  {5, 8, 1, 2, 10}.

So, the mean of data

= (5+ 8 + 1 + 2 +10)/ 5

= 5.2

Then, the Value of Deviations

-0.2, 2.8, -4.2, -3.2, 4.8

So, the variance is

= (0.04 + 7.84 + 17.64 + 10.24 + 23.04) / 5

= 11.76

And, Standard deviation is

= 3.429
