Answer 2

The statement "The following sequence is arithmetic. 18, 11, 4, -3, -10, -17 is True.

To determine if a sequence is arithmetic, one must check if there is a common difference between consecutive terms. The common difference (d) can be found by subtracting any term in the sequence from the term immediately following it.

Let's calculate the common difference for the given sequence:

- For the first two terms: (11 - 18 = -7)

- For the next two terms: (4 - 11 = -7)

- For the following two terms: (-3 - 4 = -7)

- And for the last two terms provided: (-10 - (-3) = -10 + 3 = -7)

 Since the difference between each pair of consecutive terms is constant and equal to \(-7\), this confirms that the sequence is indeed arithmetic. Therefore, the statement is True.

The slope is change in y/change in x, so we have (y1-y2)/(x1-x2). This is the same no matter what's y1 or y2 as long as y1 is in the same point as x1. Plugging them in, we get (7-(-3))/(1-(-4))=10/5=2 as the slope. Therefore, we can make the function y=mx+b and since m is the slope, we have y=2x+b. Plugging -4 in for x and -3 in for y, we get -3=2*(-4)+b=-8+b. Adding 8 to both sides, we get b=5, meaning that we have y=2x+5. However, we have to put it in the form ax+by=c. To do that, we can subtract 5 from both sides to get -5+y=2x. Next, we can subtract y from both sides to get -5=2x-y

How does the radius of a positive and negative ion compare to a neutral atom?

Answers

A neutral atom contains equal amount of proton and electron.

A negative ion contains extra electrons hence there is additional outer shell so it is expected that the radius is bigger than that of a neutral atom.

While a positive ion contains less electron so there is less outer shell so the radius is smaller than that of a neutral atom.

So area (a) = 1/2 (base)(height) = 1/2bh
We have the b at 25m, but to find the h we need to drop an altitude or apothem down that is perpendicular to the base (90°). Now we have to do some trig to determine that h.
Since we're given that AB is 40m, and <B is 80°, we can set up a SOH-CAH-TOA equation:
The hypotenuse = 40m, and our height is opposite <B, therefore sin (80) = h/40,
h = 40 × sin (80) = 40 × 0.985 = 39.39m
Now, a = 1/2bh = 1/2 (25m)(39.4m)

The width of a rectangle is 2m less than the length. the area is 48m squared. find the dimensions

Answers

Let the length = L
Then the width, W = L - 2

A = LW

48 = L(L - 2)

48 = L^2 - 2L

L^2 - 2L - 48 = 0

(L - 8)(L + 6) = 0

L - 8 = 0   or   L + 6 = -6

L = 8   or   L = -6

Since the length of a rectangle cannot be a negative number,
we discard the -6.

The length is 8m
The width is 2 m less than the length, so the width is 6 m.

The length of the rectangle is 8m and the width is 6m

This question involves the area of a rectangle and we can use the formula to solve this problem.

Data given;

A = 48m^2w = (L - 2)mArea

The area of a rectangle is given as

[tex]A = L * W[/tex]

l = lengthw = width

substitute the values and solve

[tex]A = lw\\48 = L * ( L - 2)\\48 = l^2 -2l\\l^2 -2l - 48 = 0[/tex]

solve this quadratic equation to find the length

a = 1, b = -2, c = -48

[tex]l = \frac{-b+-\sqrt{b^2 - 4ac} }{2a} \\l = \frac{-(-2)+-\sqrt{(-2)^2-4*1*(-48)} }{2*1} \\l = 8[/tex]

Taking only the positive value of l, l = 8

but we also know that

[tex]w = l -2\\w = 8 -2\\w= 6[/tex]

from the above, the length of the rectangle is 8m and the width is 6m

Write the equation of the function whose graph is shown.

Answers

Answer:

[tex]y=1(x-5)^2 + 3[/tex]

Step-by-step explanation:

Given : from the graph vertex is (5,3)

Also graph passes through point (8,12)

We use vertex form of quadratic equation

General vertex form is

[tex]y=a(x-h)^2 + k[/tex]

vertex is (5,3)

h= 5 and k =3

So equation becomes [tex]y=a(x-5)^2 + 3[/tex]

Now we need to find out 'a'

We use (8,12) to find out 'a'

Plug in x=8 and y = 12

[tex]12=a(8-5)^2 + 3[/tex]

[tex]12=a(3)^2 + 3[/tex]

12= 9a + 3

subtract 3 on both sides

9 = 9a

divide both sides by 9

so a=1

Final equation is

[tex]y=1(x-5)^2 + 3[/tex]

An equation of the function of this graph is equal to [tex]y=1(x-5)^2 + 3[/tex]

Given the following data:

Points on the x and y-axis = (8, 12).Vertex (h, k)= (5, 3).

How to write a function.

The vertex form of a quadratic equation can be used to write an equation of the function of a graph.

Mathematically, the vertex form of a quadratic equation is given by this formula:

[tex]y=a(x-h)^2 + k[/tex]

Substituting the given parameters into the formula, we have;

[tex]12=a(8-5)^2 + 3\\\\12=(3a)^2+3\\\\9a^2=12-3\\\\9a^2=9\\\\a^2=1[/tex]

a = 1.

Answers

Normally, the first thing you do is establish the border line, by changing the > into an =. However, in all 4 answers, the line is the same, so that is not what the question is about. We need to know two things:

- do we need to be on the left or the right side of the line to find points that satisfy the equation?
- is the line itself included or not

To start with the second question, since y has to be greater than and not equal, the line itself is NOT included in the solution area. This means the correct answer has to have a dashed line.

The general way to know on which side of the line you have to be, is to fill in one easy point and see if the equation holds. Let's fill in (0,0), (but any point will do).

you get: 0 > 1 - 3*0, which is NOT true. So (0,0) is in an area that is not our solution. The top-right picture is therefore not the answer.

What remains is the bottom-right picture, that is the correct shaded area. All points in the shaded area satisfy the equation.

Explain the difference between exponential growth and exponential decay

Answers

Exponential growth is the function
[tex]y = a^{x} , a\ \textgreater \ 1[/tex]
Exponential decay is the function
[tex]y = a^{x} , 0\ \textless \ a\ \textless \ 1[/tex]
So, the basic difference is that in growth the base is more than 1, and in decay the base is more than 0 but less than 1.

Final answer:

Exponential growth occurs when a population increases at an increasing rate, whereas exponential decay involves a decrease at a rate proportional to the current size. Logistic growth, adding the concept of carrying capacity, more accurately reflects natural populations with initial exponential increase followed by a plateau as resources become limited.

Explanation:

The key difference between exponential growth and exponential decay lies in the direction and rate at which a quantity changes over time. Exponential growth occurs when a population grows at an increasing rate as time passes, often depicted as a J-shaped curve, whereas exponential decay describes a process of decrease at a rate proportional to the current value, leading to a rapid reduction in size or quantity over time.

In the context of biology and population growth, exponential growth describes how populations can grow dramatically when there are no limits to resources or space. This type of growth can be formalized as a mathematical model where the population after n time periods has increased by a factor of 2n when the base growth rate is 2. In natural populations, this is idealized and does not usually last long as resources become depleted and other limiting factors come into play. On the other hand, exponential decay in biology might refer to the rapid loss of a population due to harsh conditions, lack of resources, or other negative impacts.

Determine whether 2y=3x-1 represents a direct variation. if it​ does, find the constant of variation.

Answers

Answer choices for this question? 

The equation 2y=3x-1 does not represent a direct variation in its strict definition, as it includes a y-intercept. If the y-intercept is ignored, the constant of variation would be k = 3/2.

The equation 2y=3x-1 represents a direct variation if it can be written in the form y = kx, where k is the constant of variation. To determine if this equation represents a direct variation, we can solve it for y:

Divide both sides of the equation by 2 to isolate y:
y = (3/2)x - 1/2.

Since we can express y as an equation of the form y = kx + b, with b being a constant, it does not represent a pure direct variation, as direct variation should have a form y = kx without the constant term.

However, if the question is interpreted to include such linear relationships as direct variations despite the y-intercept, then the constant of variation would be k = 3/2.

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We need to find the unit fractions to convert 15 days into seconds.

1 day = 24 hour

1 hour = 60 minutes.

1 minutes = 60 seconds

Therefore, 24 hours = 24 x 60 x 60  = 86400 seconds

There are 86400 seconds in one day.

Then 15 days = 15 x 86400 = 1,296,000

Answers

As the number of college students increases, the number of buses tends to increase.

Answer:

Step-by-step explanation:

Given that the correlation coefficient between the number of college students in a city and the number of city buses is 0.89.

We find that correlation coefficient is a measure of linear association between two variables.

When the absolute value of correlation coefficient is near 1, there is strong correlation. If correlation has a positive sign, there is a posiitive association between the two variables.

Here the correlation coefficient is positive and also near 1.  Thus there is a strong linear correlation between the two variables.

Or whenever there is an increase in one variable there will be an increase in other variable also.
