What is true about the points on the graph of y=2x?

Answer:

2·2·2·2 = 16

Step-by-step explanation:

everytime a number is raised by another, that means you are going to multiply the base number  times itself as many times as the exponents tells you. this is a little but tricky to explain, so let me give you some examples:

2² → in this case the base number is 2 and the exponent is 2 as well, so you will multiply 2 times itself, 2 times:

2² = 2 · 2 = 4

2³ → in this case the base number is 2 and the exponent is 3, so you will multiply 2 times itself, 3 times:

2³ = 2 · 2 · 2 = 8

In the question asked, 2 is being raised by 4, so you will multiply 2 times itself, 4 times:

2^4 = 2·2·2·2 = 16

the same format will be used regardless of the base number and the exponent

Answer: intersecting but not perpendicular

Step-by-step explanation: Let's start by eliminating a few options.

First off, parallel lines are coplanar lines that do not intersect.

In the diagram shown, lines i and k do intersect

so option A doesn't make any sense.

We can also eliminate option C because by definition,

parallel lines do not intersect so we can cross this off.

We also can't conclude that lines i and k are perpendicular,

because we don't have a box at the vertex and from the

diagram shown, it doesn't look like they form a perfect right angle.

That leaves us with option D.

Notice that these two lines cross at a point.

When two lines cross at a point, we say that they intersect.

So they are intersecting lines but not perpendicular.

Answer:

8q - 2

Step-by-step explanation:

Use PEDMAS .

4q + 2(3q - 1) - 8q ÷ 2² = 4q + 2*3q - 2* 1 - 8q ÷ 4  

                                     = 4q + 6q - 2 - 2q          {Combine like terms}

                                     = 4q + 6q - 2q  - 2

                                     = 8q - 2

Answer:

(Part A.)

Step 2

(Part B.)

Step 1. 2(x + 9) = 4(x + 7) + 2

Step 2. 2x + 18 = 4x + 28 + 2

Step 3. 2x + 18 = 4x + 30

Step 4. -12 = 2x

Step 5. -6 = x

Step-by-step explanation:

(Part A.)

Emily incorrectly distributes 4(x + 7). This should be 4x + 28 instead of 4x + 7.

(Part B.)

On Step 2, Emily should have properly distributed 4(x + 7) as 4x + 28. Step 4, -8 is not a coefficient of x.

Work Shown:

L = number of students in Lee's class

F = number of students in Fred's class

Lee has 1.1 times as many students compared to Fred

This means we have this equation

L = 1.1F

Whatever the value of F is, we multiply that by 1.1 to get the value of L

The two amounts L and F add to 42 total students

L+F = 42

1.1F + F = 42 .... replace L with 1.1F

2.1F = 42

F = 42/(2.1)

F = 20 .... Fred has 20 students

L = 1.1*F

L = 1.1*20

L = 22 .... Lee has 22 students

------------

Check:

L+F = 22+20 = 42

this confirms the answer

The correlation coefficient is 0.505 rounded to three decimal places.

The correlation coefficient is a statistic that determines the relationship between two variables, X and Y.

It is used to determine the strength and direction of the relationship between the two variables.

The correlation coefficient ranges from -1 to +1, with -1 indicating a perfect negative correlation, 0 indicating no correlation, and +1 indicating a perfect positive correlation.

The formula for the correlation coefficient is:

r = [n(∑xy) - (∑x)(∑y)] / [√{n(∑x²) - (∑x)²} × √{n(∑y²) - (∑y)²}]

where n is the number of observations, x and y are the two variables, ∑xy is the sum of the product of the two variables, ∑x and ∑y are the sums of the two variables, ∑x² and ∑y² are the sums of the squares of the two variables

Using the formula, the correlation coefficient can be calculated as follows:

Given the following data:10 15.8

Calculating the necessary sums

∑x = 10∑y = 15.8∑xy = (10)(15.8) = 158∑x² = 100∑y² = 249.64

Using the formula:

r = [n(∑xy) - (∑x)(∑y)] / [√{n(∑x²) - (∑x)²} × √{n(∑y²) - (∑y)²}]

r = [2(158) - (10)(15.8)] / [√{2(100) - (10)²} × √{2(249.64) - (15.8)²}]

r = [316 - 158] / [√(200) × √(467.68)]

r = 158 / [14.1421 × 21.6266]r = 0.505

The correlation coefficient is 0.505 rounded to three decimal places.

The compound interest formula can be used to calculate the interest rate Tumelo should invest his initial amount at.

This formula is represented as follows: FV = PV(1 + r/n) where: FV = future valuePV = present value or initial amountr = interest rate = number of compounding periods in a year and = number of yearsThis formula assumes that the interest is compounded quarterly.

Therefore, we have four compounding periods in a year. Substituting the given values into the formula:FV = PV(1 + r/n)nt28000 = 14600(1 + r/4)^(4*6)28000/14600 = (1 + r/4)^24Dividing both sides by 14600 gives:1.9178 = (1 + r/4)^24Taking the logarithm of both sides gives:

ln(1.9178) = ln[(1 + r/4)^24]Applying the logarithmic rule for exponents gives:

ln(1.9178) = 24ln(1 + r/4)Solving for r gives:r = 4[(1.9178)^(1/24) - 1]r = 0.0362 or 3.62%Therefore, Tumelo should invest his initial amount at an interest rate of 3.62%, compounded quarterly, to achieve his goal of withdrawing R28000 in 6 years.

My preferred course is Statistics because I enjoy analyzing data, making predictions and using probability to make decisions. Statistics is useful in many fields including business, economics, and science.

Mathematics is a fundamental subject that is essential for all students to learn in school. As students advance through different math courses, they will find that there are more connections between them than they might initially realize.

In this essay, I will discuss the similarities and differences between the math courses I have taken and how they influenced my choice of preferred course.  

 The courses I have taken include Algebra, Geometry, Calculus, and Statistics. In Algebra and Geometry, I found that both subjects involve solving problems using formulas and equations.

In Algebra, I learned how to solve linear equations and inequalities while in Geometry, I learned how to measure the shapes of objects and their angles.

On the other hand, Calculus was different from the other courses because it involved analyzing and solving problems using limits, derivatives, and integrals.

Statistics, however, was the course that I found most useful because it allowed me to make informed decisions based on data analysis.    Additionally, it is a prerequisite for most advanced degrees in these fields.

I believe that my experience in the other math courses played a significant role in helping me understand Statistics better because they provided a strong foundation of mathematical concepts and problem-solving skills.

The decay factor is the decay constant subtracted from 1.

The decay factor is (c) [tex]0.87[/tex]

We have:

[tex]T_\frac{1}{2} = 5.26[/tex]

First, we calculate the decay constant [tex](\lambda)[/tex]

This is calculated using

[tex]\lambda = \frac{0.693}{T_\frac{1}{2}}[/tex]

So, we have:

[tex]\lambda = \frac{0.693}{5.26}[/tex]

[tex]\lambda = 0.13175[/tex]

Next, we calculate the decay factor (b) using:

[tex]b =1 - \lambda[/tex]

So, we have:

[tex]b =1 - 0.13175[/tex]

[tex]b =0.86825[/tex]

Approximate to 2 decimal places

[tex]b =0.87[/tex]
