Answer:

Compound interest is calculated by;

Initial amount x (100%xinterest%)^(years)

My workings which I also checked with another and they agree doesn't come back to your options. But closest answer is B.

Step-by-step explanation:

$450x(1.048^4) = $542.82

$750x(1.0375^4) = $868.99

$542.82 + $868.99 =  $1,411.81

Step-by-step explanation:

Rule for the dilation of a point by a scale factor 'k' about the origin is,

(x, y) → (kx, ky)

If the scale factor for the dilation is [tex]k=\frac{6}{5}[/tex],

Rule for the dilation,

A(x, y) → A'[tex](\frac{6}{5}x,\frac{6}{5}y)[/tex]

If the coordinates of point A' (Image) is given and we have to find the coordinates of point A (Preimage),

Rule for the dilation,

A'(x, y) → [tex]A(\frac{5}{6}x,\frac{5}{6}y)[/tex]

Answer:

B. David's sprinkler uses less water per minute.

Step-by-step explanation:

David's sprinkler uses 10 gallons every 5 minutes, which is 2 gallons a minute.

George's sprinkler uses 6 gallons a minute, which means it uses more.

David's sprinkler uses less and it uses exactly 2 gallons a minute.

Answer:

$2675 ; $1495 ; $400

Step-by-step explanation:

Given the regression model :

y = 175+ 1.2x1 +400x2

y = average monthly rent

x1 = square footage of apartment

x2 = location ; 1 if located in town center ; 0 if otherwise.

1.)

Predict average monthly rent for an apartment located in town center and has 1750 ft²

y = 175+ 1.2(1750) + 400(1)

y = 175 + 2100 + 400

y = $2675

11.) average monthly rent for an apartment located in the suburbs that has 1,100 square feet.

y = 175 + 1.2(1100) + 400(0)

y = 175 + 1320 + 0

y = $1495

111) An apartment is worth $400 more if located in town center (slope of x2)

An apartment is worth 400 dollars more if located in the center of the town than the located in the suburbs.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more two variables.

The given linear regression model is shown below.

[tex]\rm y = 175 + 1.2 x_1 + 400 x_2[/tex]

y = Average monthly rent

x₁ = square footage of apartment

x₂ = location

1.  Predict the average monthly rent for an apartment located in the center of town and has 1750 square feet.

y = 175 + 1.2 × 1750 + 400 × 1

y = 175 + 2100 + 400

y = $2675

2.  The average monthly rent for an apartment located in the suburbs has 1100 square feet.

y = 175 + 1.2 × 1100 + 400 × 0

y = 175 + 1320

y = $1495

An apartment is worth 400 dollars more if located in the center of the town than the located in the suburbs.

Answer:

The minimum number of assignment statements needed is 5

Step-by-step explanation:

To write the algorithm, we apply the strategy of interchanging the values of variables in the assignment statements.

Assume "tmp" is the new variable, let assign tmp to w

The algorithm is:

Procedure exchange (w,x,y,z: integers)

 tmp := w

    w := x

     x := y

     y := z

     z := tmp

    return (w,x,y,z)

end

From the algorithm, it is obvious that there will be a minimum of 5 assignment statements needed.

Answer:

[tex]v=\frac{80}{3}\pi \frac{m}{min}[/tex]

Step-by-step explanation:

In order to start solving this problem, we can begin by drawing a diagram of what the problem looks like (see attached picture).

From that diagram, we can see that we have a triangle we can analyze. We'll call the angle between the vertical line and the slant line [tex]\theta[/tex]. And we'll call the distance between W and the point we are interested in l.

Now, there are different things we need to calculate before working on the triangle. For example, we can start by calculating the angle [tex]\theta[/tex].

From the diagram, we can see that:

[tex]tan \theta = \frac{l}{3}[/tex]

when solving for [tex]\theta[/tex] we will get:

[tex]\theta = tan^{-1} (\frac{l}{3})[/tex]

we could use our calculator to figure this out, but for us to get an exact answer in the end, we will leave it like that.

Next, we can calculate the angular velocity of the beam. (This is how fast the beam is rotating).

We can use the following formula:

[tex]\omega = \frac{2\pi}{T}[/tex]

where T is the period of the rotation. This is how long it takes the beam to rotate once. So the angular velocity will be:

[tex]\omega = \frac{2\pi}{3} \frac{rad}{s}[/tex]

Next, we can take the relation we previously got and solve for l, so we get:

[tex]tan \theta = \frac{l}{3}[/tex]

[tex]l = 3 tan \theta[/tex]

Now we can take its derivative, so we get:

[tex]dl = 3 sec^{2} \theta d\theta[/tex]

and we can divide both sides of the equation into dt so we get:

[tex]\frac{dl}{dt} = 3 sec^{2} \theta \frac{d\theta}{dt}[/tex]

in this case [tex]\frac{dl}{dt}[/tex] represents the velocity of the beam on the wall and [tex]\frac{d\theta}{dt}[/tex] represents the angular velocity of the beam, so we get:

[tex]\frac{dl}{dt} = 3 sec^{2} (tan^{-1} (\frac{l}{3})) (\frac{2\pi}{15})[/tex]

we can simplify this so we get:

[tex]\frac{dl}{dt} = (\frac{2\pi}{5})sec^{2} (tan^{-1} (\frac{l}{3}))[/tex]

we can use the Pythagorean identities to rewrite the problem like this:

[tex]\frac{dl}{dt} = (\frac{2\pi}{5})(1+tan^{2} (tan^{-1} (\frac{l}{3})))[/tex]

and simplify the tan with the [tex]tan^{-1}[/tex] so we get:

[tex]\frac{dl}{dt} = (\frac{2\pi}{5})(1+(\frac{l}{3})^{2})[/tex]

which simplifies to:

[tex]\frac{dl}{dt} = (\frac{2\pi}{5})(1+(\frac{l^{2}}{9}))[/tex]

In this case, since l=1, we can substitute it so we get:

[tex]\frac{dl}{dt} = (\frac{2\pi}{5})(1+(\frac{1}{9}))[/tex]

and solve the expression:

[tex]\frac{dl}{dt} = (\frac{2\pi}{5})(\frac{10}{9})[/tex]

[tex]\frac{dl}{dt} = \frac{20}{45}\pi[/tex]

[tex]\frac{dl}{dt} = \frac{4}{9}\pi \frac{m}{s}[/tex]

now, the problem wants us to write our answer in meters per minute, so we need to do the conversion:

[tex] \frac{dl}{dt} = \frac{4}{9}\pi \frac{m}{s} * \frac{60s}{1min} [/tex]

[tex]velocity = \frac{80}{3} \pi \frac{m}{min}[/tex]

Answer:

When you read a sentence, you may first look for the subject or what the sentence is about. The subject usually appears at the beginning of a sentence as a noun or a pronoun. A noun is a word that identifies a person, place, thing, or idea. A pronoun is a word that replaces a noun. Common pronouns are I, he, she, it, you, they, and we. In the following sentences, the subject is underlined once.

Step-by-step explanation:

You will often read a sentence that has more than one noun or pronoun in it. You may encounter a group of words that includes a preposition with a noun or a pronoun. Prepositions connect a noun, pronoun, or verb to another word that describes or modifies that noun, pronoun, or verb. Common prepositions include in, on, under, near, by, with, and about. A group of words that begin with a preposition is called a prepositional phrase. A prepositional phrase begins with a preposition and modifies or describes a word. It cannot act as the subject of a sentence. The following circled phrases are examples of prepositional phrases.

Answer:

x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 = 7(x + 1)

Step-by-step explanation:

Equations

The situation can be written as an algebraic equation by setting the variables as follows:

x = first integer

x + 1 = second integer

x + 2 = third integer

x + 3 = fourth integer

x + 4 = fifth integer

x + 5 = sixth (and last) integer

The sum of all six numbers must be equal to 7 times the second number, thus:

x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 = 7(x + 1)

18√7x⁶

Step-by-step explanation:

Given the expression 7√28x⁶+4√7x⁶, we are to fund the sum in its simplest form as shown;

7√28x⁶+4√7x⁶

= 7√(7*4)x⁶+4√7x⁶

= 7*2√7x⁶+4√7x⁶

= 14√7x⁶+4√7x⁶

Factor out the like term

= 2√7x⁶(7+2)

= 2√7x⁶(9)

= 18√7x⁶

Hence the sum is equivalent to 18√7x⁶

Answer:

Step-by-step explanation:

If you were really careful, you should say there is no solution. You have to know that x and 8 are parallel.

The side showing 6 and 6 are sides of a large and small triangle

The large triangle is 6 + 6 = 12

The small triangle is 6

So 8 and x are going to be in the same proportion.

x/6 = 8/12      Cross multiply

12x =48

x = 48/12

x = 4

Answer:

Si, en tanto los kilómetros siguen un patrón decimal, al igual que los números enteros.

Step-by-step explanation:

La pregunta refiere a si el .1 implica un mismo valor en 20.1 km que en 5.1, es decir, en un numero sin unidad de medición.

Y la respuesta es positiva, en tanto los kilómetros, al igual que los números enteros, se rigen por un patrón decimal, es decir, donde los números pueden descomponerse en unidades divisibles por diez. Así, el .1 implica que, tanto en el kilómetro como en el numero entero, se trata del 10% del valor de la unidad en cuestión.
