Answer:

principal is $15112

Step-by-step explanation:

25000=P(1+ 0.028/12)^(12times18)

The principal amount of the savings is $15111.6

The given parameters are:

Amount is calculated using:

A = P(1 + r/n)^nt

So, we have:

25000 = P(1 + 2.8%/12)^(12 * 18)

Make P the subject

P = 25000/(1 + 2.8%/12)^(12 * 18)

Evaluate the expression

P = 15111.6

Hence, the principal amount is $15111.6

Answer:

the answer is D, 30% of his budget is spent on clothes

Answer:

We can not see the graph, but that does not matter.

For a function y = f(x), the domain is the set of the possible values of x that we can input in the function, and the range is the set of the possible outputs.

First, for the domain, we start assuming that the domain is the set of all real numbers.

Then we look at our function, there is a point that causes a problem?

(a problem can be a zero in a denominator, for example)

Well, we have a quadratic equation, then we can not have any "x" in a denominator, then there are not problems, which means that the domain is the set of all real numbers.

For the range we first need to find the minimum (or maximum value) of f(x).

Here we know that the vertex is (1, - 3)

If the arms of the graph open upwards, then the minimum is at the vertex, which means that the minimum value of y is y = -3

And the arms go upwards infinitely, so there is no upper limit.

Then the range is the set of all numbers such that:

-3 ≤ y

Now, if the arms of the graph open downwards, then the maximum is at the vertex, which means that the maximum of our function is at y = -3

And with similar thinking than in the above case, we can find that the range is:

R:  y ≤ -3.

Answer: x=8

Step-by-step explanation:

We know that it is a square, so the diagonals divide the four triangles evenly.

A whole circle will have 360°. When it is divides into 4, each angle will be

360/4=90°

The vertex of each triangle will be 90°

And the given vertex equation is 8x+26

8x+26=90

8x+26-26=90-26

8x=64

x=8

Answer:

1: The correction option is B) Negative

Explanation

In economic theory, the Philips curve depicts the relationship between unemployment and inflation as a negative one. In order words, when inflation goes up, unemployment reduces.

The logic behind that thinking is, that inflation, which is the general increase in prices of goods/commodities and services is good for business. Business owners are quick to adjust to higher prices regardless of how it is induced and sometimes even profit from it in sectors not affected by inflation. So in such sectors, as business improves,  it is assumed that there is a requirement to being in more hands to help with the expansion of the business.

2. The correct option is B) Holds for certain time periods

Explanation

Social scientists and researchers have plotted the data across various periods (20 years) using data from the US economy.

The following results emerged:

So the correct answer is B.

3. The correct answer is True:

Explanation

As seen from the analysis above, the negative relationship remains largely true for most of the periods examined. Hence it is more pragmatic to expect a dip in unemployment whenever there is a spike in the CPI.

Answer:

809 km²

Step-by-step explanation:

I can split this into 3 rectangles. One is 25 by 17, another is 24 by 13, and the last one is 6 by 12. (I had gotten 13 for the second rectangle because 25 - 12 = 13.)

(25 * 17) + (24 * 13) + (6 * 12) {17 is the first number after a multiple of 4 (16). As a result, 25 by 17 will end in "25." 25 by 17 is 425.}

425 + (24 * 13) + (6 * 12) {24 by 13 is 312.}

425 + 312 + (6 * 12) {6 by 12 is 72.}

425 + 312 + 72 {From left to right, add 425, 312, and 72 to get 809}

737 + 72

809 km²

The area of this figure is 809 km².

Answer:

The unique sequence of rigid motions that maps quadrilateral ABCD to EFGH are;

B. A reflection over the y-axis followed by a translation of (I, y) → (I, y - 6)

('I' is the image of 'x' after reflection)

Step-by-step explanation:

The coordinates of the vertices of the quadrilateral ABCD are;

A(-5, 4), B(-2, 4), C(-2, 1), and D(-5, 2)

The coordinates of the vertices of the quadrilateral EFGH are;

E(5, -2), F(2, -2), G(2, -5), and H(5, -4)

By analysis, we have;

The signs of the x-coordinate of the preimage and the image are opposite, therefore, one of the rigid motions is a reflection across the y-axis

Similarly, the common difference between the y-coordinate values of the image and the preimage are;

-2 - 4 = -6

-2 - 4 = -6

-5 - 1 = -6

-4 - 2 = -6

The common difference between the y-coordinates of the image and the preimage is -6, therefore, the y-values are obtained by a translation of y - 6 units

Therefore, the unique sequence of rigid motions that maps quadrilateral ABCD to EFGH are a reflection over the y-axis followed by a translation of (I, y) → (I, y - 6).

Answer:

t=5

Step-by-step explanation:

Vertical angles are congruent

So we put the value equivalent to each other

110=4t+90

Isolate t

110=4t+90

-90      -90

20=4t

Divide to isolate t

20/4=4t/4

Answer:

Perimeter = 72

Step-by-step explanation:

Notice that the adjacent (next to) lengths by each corner are equal in length.

This occurs when the quadrilateral is circumscribed.

Since 4.2 is adjacent to the length which makes up the total side 20.

20 – 4.2 = 15.8.

And 15.8 + 4.2 = 20.

(7 + 9) + (9 + 4.2) + (4.2 + 15.8) + (15.8 + 7) =

(16) + (13.2) + (20) + (22.8) =

(16 + 20) + (13.2 + 22.8) =

36 + 36 =

Step-by-step explanation:

Answer:

Jesse = 18yrs

Adam = 9yrs

Denise = 6yrs

Step-by-step explanation:

Denise = x

Adam = x+3

Jesse = 2(x+3)

x+x+3+2x+6 = 33

4x+9 = 33

4x = 33-9

4x = 24

x = 6yrs

Substitute :

Denise = 6

Adam = 6+3 = 9

Jesse = 2(6+3) = 2(9) = 18

Answer:

The answer is -5.

Step-by-step explanation:

The absolute value of -9 is 9.

Then it would be like 4= x + 9.

If you solve it, you get -5.

A. y = 5, is the correct answer.

B, C, D are all able to form into the y = mx + b equation, so it's not correct. A is not able to form that equation, therefore, A is correct. Hope that helps :)

Answer:

  c)  x = 6

  d)  x = 2

Step-by-step explanation:

In general, you want to "undo" what is done to the variable.

When variable terms are on both sides of the equal sign, you want to collect them on one side of the equal sign first. I like to do that by adding the opposite of the variable term with the lowest (most negative) coefficient.

Whatever you do to one side of the equation must also be done to the other side.

__

c) 2(x +3) = 18

  x +3 = 9 . . . . . . divide both sides by 2

  x = 6 . . . . . . . . . subtract 3 from both sides

__

d) 2x +15 = 27 -4x

  6x +15 = 27 . . . . . . . add 4x to both sides

  6x = 12 . . . . . . . . . . . subtract 15 from both sides

  x = 2 . . . . . . . . . . . . . divide both sides by 2
