A house cost $120,000 when it was purchased. The value of the house increases by 10% each year. Find the rate of growth each month and select the correct answer below.

Answers

Answer 1

well, the house is increasing by 10% each year, so whatever the current price is, the new price is THAT plus 10%, well, since THAT is 100%, shouldn't that be 100% + 10%, or 110%?

[tex]\bf \qquad \textit{Amount for Exponential Growth}\\\\ A=I(1 + r)^t\qquad \begin{cases} A=\textit{accumulated amount}\\ I=\textit{initial amount}\to &120,000\\ r=rate\to 10\%\to \frac{10}{100}\to &0.10\\ t=\textit{elapsed time}\\ \end{cases} \\\\\\ A=120000(1+0.10)^t\implies \begin{array}{lclll} A=120000(&1.1&)^t\\ &\uparrow \\ &rate\\ &of\\ &growth \end{array}[/tex]

1.1 is the decimal format, but you can simply multiply it by 100 to get the percentage, 1.1 * 100 = 110%

a bowl contains 80 M&M candies If 15 are orange what fraction of the candies is NOT orange. Answer reduced to lowest terms

Answers

65/80 can be reduced to 13/16.

So, it says that there are 80 M&M candies in a bowl. 15 are orange, so that means the others aren't orange. So, then you would do (the total number of M&M candies in the bowl)-(the number of orange M&M candies)=The number of M&M candies that are not orange. So, 80-15=65.
So, they are 65/80 in the bowl that aren't orange. But we aren't done yet. We need to find the lowest term for 65/80. First, we'll need to find what can go into 65 and 80 evenly without leaving a remainder. Yes, you guessed it, five can go into 65 and 80 without leaving a remainder. So, 65 divided by 5=13 and 80 divided by 5=16. So, your final answer is 13/16.
13/16 is the final answer. This is the lowest possible term for the number pf candies that aren't orange.
65/80=13/16
13/16 are the number of M&M candies that aren't orange.

how can exponential and logarithmic functions be created to use in real world situations?

Answers

In realistic world there are so many examples which use exponential and logarithmic functions.

Use of Logarithmic function
We can find use of logarithmic function in measuring earthquake (Richter Scale) , the brightness of stars , and chemistry(pH balance , measure of acidity and alkalinity)

For example:
In Richter Scale , a logarithmic function that is used to measure the magnitude of earthquake.
If A = measure of amplitude of earthquake wave.
[tex]A_o[/tex] = Amplitude of smallest detectable wave.
From this we can find R the Richter scale measure of magnitude of earthquake.
[tex]R = log \frac{A}{A_o} [/tex]

Use of Exponential Function:

Exponential function may use in finding compound interest , population growth , radioactivity decay , etc.

For example :
As we know the formula for compound interest is
[tex]A = P(1+ \frac{r}{n})^{nt} [/tex]
Where P is principal amount , r = rate of interest(decimal) , n is the number of compounding period , t is time.

This net folds into the cube shown beside it. On the cube, which letter will be on the side opposite D?

Answers

Final answer:

Without more information or a diagram, it's hard to give a specific answer. However, on a cube net, the face opposite 'D' is likely the one not directly connected to 'D' on the plane of the net.

Explanation:

Unfortunately, without a diagram or more context, it's difficult to provide a definitive answer to the question. However, typically on a cube net, sides that are opposite each other when the net is folded into a cube are adjacent (next to each other) on the net. For example, if 'D' were on a flat square in the center of the net, the squares directly connected to it (on the top, bottom, left, and right) on the plane of the net would end up being the sides adjacent to 'D' when the cube is formed. The square not connected directly to 'D' on the plane would be opposite 'D' once the cube is formed.

What are the vertex, focus, and directrix of the parabola with the equation x^2+8x+4y+4=0

Answers

We are given the function x^2+8x+4y+4=0. To determine the characteristics of this function, we need to write it in the standard form as follows:

x^2+8x+4y+4=0
4y = -x^2 - 8x - 4
y = (-1/4)x^2 - 2x - 1

To determine the vertex and the focus of the parabola, we write it in the form (y+k)^2 = x+h by completing the square method.

y + 1 = (-1/4)x^2 - 2x
y +1 = (-1/4)(x^2 + x/2)
y +1 - 1/64 = (-1/4)(x^2 + x/2 + 1/16)
y + 15/16 = (-1/4) (x + 1/4)^2

The vertex would be at point ( -1/4, -15/16)
The focus would be determined as follows:
4p=-1/4 so p=-1/8
focus = (-1/4+(-1/8),-15/16) = (-3/8,-15/16)

Directrix = x = h - p
x = -1/4 - -1/8 = -1/8

Answer:

Vertex=(-4,3)

Focus=(-4, 2)

Directrix: y=4

Step-by-step explanation:

Given the equation

[tex]x^2+8x+4y+4=0[/tex]

we have to find the vertex, focus, and directrix of parabola.

[tex]x^2+8x+4y+4=0[/tex]

[tex]y=\frac{-x^2}{4}-2x-1[/tex]

[tex]h=\frac{-b}{2a}=\frac{2}{2(\frac{-1}{4})}=-4[/tex]

Now, k can be calculated by putting x=4 and y=k in given equation

[tex]k=-1-\frac{16}{4}-2(-4)=-1-4+8=3[/tex]

The vertex is (h,k) i.e (-4,3)

[tex]y=\frac{-x^2}{4}-2x-1[/tex]

[tex]y=\frac{1}{4}(-x^2-8x-4)[/tex]

[tex]=\frac{1}{4}(-x^2-8x-16+16-4)[/tex]

[tex]y=\frac{1}{4}(-(x+4)^4+12)[/tex]

[tex]y=\frac{-1}{4}(x+4)^2+3[/tex]

which is required vertex form [tex]4p(y-k)=(x-h)^2[/tex]

gives p=-1

Focus=(-4, 3+(-1))=(-4,2)

Now directrix can be calculated as

y=3-p=3-(-1)=4

-13x=90-2y
-6x=48-2y

Answers

Final answer:

The solution to the system of equations is x = 6 and y = 84.

Explanation:

The given equations are:

-13x = 90 - 2y

-6x = 48 - 2y

To find the values of x and y, we can solve the system of equations. We can start by multiplying the second equation by -2 to eliminate the y variable. This gives us:

12x = -96 + 4y

Now we have two equations:

-13x = 90 - 2y

12x = -96 + 4y

We can add the two equations together:

-13x + 12x = 90 - 2y + (-96 + 4y)

-x = -6

Then, we can divide both sides of the equation by -1 to solve for x:

x = 6

Substituting the value of x back into one of the original equations, we can solve for y. Let's use the first equation:

-13(6) = 90 - 2y

-78 = 90 - 2y

-2y = -168

y = 84

Therefore, the solution to the system of equations is x = 6 and y = 84.

I need help please :( !!!

Answers

Number of cans donated the first week = 132
Number of cans donated the second week = 146
Number of cans donated the third week = c, where c is some positive number

Add up the three values (132, 146, and c) to get 132+146+c. I'm choosing not to simplify because each answer choice hasn't simplified either.

The expression of 132+146+c represents the total amount of cans donated for weeks 1 through 3. We want "at least 325 cans", so that means the expression is 325 or larger. That translates to this inequality

[tex]132+146+c \ge 325[/tex]

The "greater than or equal to" sign indicates we want that sum to be 325 or larger.

Now we solve for c

[tex]132+146+c \ge 325[/tex]
[tex]278+c \ge 325[/tex]
[tex]278+c-278 \ge 325-278[/tex]
[tex]c \ge 47[/tex]

So the amount of cans donated for week three needs to be 47 or larger. If you collect exactly 47 cans for week three, then you meet the goal of 325 total cans. If you collect more than 47 cans for week three, then you exceed the goal of 325 total cans.

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

In summary we have the inequality
[tex]132+146+c \ge 325[/tex]
which solves to
[tex]c \ge 47[/tex]

The key idea of the transformation called a reflection is _____.

the object moves the plane a certain angle measure
the object moves in a straight line movement
the object and its image have opposite orientations
the rotating of a plane about a fixed point

Answers

The object and its image have opposite orientations

Answer: The object and its image have opposite orientations

Step-by-step explanation:

A reflection is a type of rigid transformation in which the preimage is flipped across a line of reflection to produce the image, such that the figure and its image have opposite orientations.

Since, it preserves distance.

Therefore, the points of the image have the same distance from the line as the points of pre-image on the opposite side of the line.

Hence, the right option is "the object and its image have opposite orientations".

I believe there are some choices for this question but you forgot to include. Nevertheless, I will give my observations from the given figure.

The tile PQRS is bigger than tile JKLM. A rectangle is a two-dimensional shape that has two sets of equal parallel planes. Thus, its area is equal to the length multiplied by its width.

tile PQRS = (9-5)*(12-7) = 20 units²
tile JKLM = (6-4)*(10-5) = 10 units²

Tile PQRS is larger by 10 units².

This policy has been courageously and insistently advocated for over fifteen years, and has been triumphant for perhaps ten years. As a result of this tender of the palm-branch, what has been the return? In these years there have occurred:1. The disfranchisement of the Negro.2. The legal creation of a distinct status of civil inferiority for the Negro.3. The steady withdrawal of aid from institutions for the higher training of the Negro.These movements are not, to be sure, direct results of Mr. Washington's teachings; but his propaganda has, without a shadow of doubt, helped their speedier accomplishment. The question then comes: Is it possible, and probable, that nine millions of men can make effective progress in economic lines if they are deprived of political rights, made a servile caste, and allowed only the most meager chance for developing their exceptional men? If history and reason give any distinct answer to these questions, it is an emphatic NO.andThe excerpt below is from the General Introduction to Tuskegee and Its People by Booker T. Washington:Institutions, like individuals, are properly judged by their ideals, their methods, and their achievements in the production of men and women who are to do the world's work.One school is better than another in proportion as its system touches the more pressing needs of the people it aims to serve, and provides the more speedily and satisfactorily the elements that bring to them honorable and enduring success in the struggle of life. Education of some kind is the first essential of the young man, or young woman, who would lay the foundation of a career. The choice of the school to which one will go and the calling he will adopt must be influenced in a very large measure by his environments, trend of ambition, natural capacity, possible opportunities in the proposed calling, and the means at his command.In the past twenty-four years thousands of the youth of this and other lands have elected to come to the Tuskegee Normal and Industrial Institute to secure what they deem the training that would offer them the widest range of usefulness in the activities open to the masses of the Negro people. Their hopes, fears, strength, weaknesses, struggles, and triumphs can not fail to be of absorbing interest to the great body of American people, more particularly to the student of educational theories and their attendant results.
