Drag a value, phrase, equation, or coordinates in the boxes to correctly complete the statements.

Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.


Marty first identifies the center of the hyperbola as Response area, and that the hyperbola opens Response area. Since a = Response area, the coordinates of the vertices are Response area.


The slopes of the asymptotes of this parabola are ± Response area, and the asymptotes pass through the center of the hyperbola. The equations of the asymptotes are Response area.


Once this information is gathered, the asymptotes are graphed as dashed lines, and the hyperbola is drawn through the vertices, approaching the asymptotes.

The Hooke's law is given by:

F = k*x

Where:

F = force

k = constant factor

x = distance

If F = 20 and x = 20

20 = k*20

Solving for k:

20/20 = k

k = 1

So: how far will a 29 pound mass stretch the spring?

29 = 1* x

Solving for x:

Answer:

After tax interest expenses = Interest expenses x (100 - Tax Rate) 

= 70000 x (100 - 30)% 

= 70000 x 70% 

= $49,000.00

Step-by-step explanation:

The function being one-to-one implies that every value of x, has one one vaue of y, and every value of y, has one value of x.

The inverse uses the output(y value) as an input(x value) and spits it out to get the original x value inputted into f.

Using the given point ( 2, -5 ), it implies of f(2) = -5. Since the function is one-to-one, this implies that:

Hence, the correct option is option B

The first complement of the binary addition is 00011111.

The binary addition operation works similarly to the base 10 decimal system, except that it is a base 2 system. The binary system consists of only two digits, 1 and 0.

Given that, the addition of the given number

  00011101 + 11111101

In the binary addition,

0+1 = 1

1+0 = 1

1+1 = 0

00011101 + 11111101 = 11100000

Then inverse code means first complement of the answer.

In the first complement, 0 is the inverse of 1 and 1 is inverse of 0.

11100000 = 00011111

Hence, The first complement of the binary addition is 00011111.

Repeating decimal (periodic)

1) Let's proceed with the long division of 4 by 99:

1.1) Since 4 is way smaller than 99 let's add one zero to the dividend and another for the quotient followed by a dot.

But 40 is still lesser than 99, so let's add another zero after the dot to make it 400. Now we can divide 400 by 99

1.2) Again to proceed with that division we'll need to write a zero at that 4 and another one in the quotient.

As and we can see already this a repeating decimal or periodic. This division will yield 0.0404040404.....

To find the value of a, we will use the Law of sines, so

So, replacing A = 150°, B = 12°, and b = 10 cm, we get:

Now, we need to solve for a. First, cross multiply

Then, divide by sin12

Therefore, a = 24.0 cm

Problem N 2

we have

12x-14=8x+16

solve for x

subtract 8x both sides

12x-14-8x=8x+16-8x

4x-14=16

Adds 14 both sides

4x-14+14=16+14

subtract 6x both sides

12x-14-6x=6x+16-6x

6x-14=16

adds 14 both sides

6x=16+14

6x=30

divide by 6 both sides

x=30/6

The laws of logarithms will come in handy in helping to obtain the points for the log from its inverse.

Before we commence, the two laws of logarithms that we will be using is that

log₄ 4ᶜ = c (log₄ 4)

And

log₄ 4 = 1

So, no matter the value of inverse given, a simple mathematical evaluation will give the log points.

when x = 1

f(x) = log₄ x

f(1) = log₄ 1 = log₄ 4⁰ = 0 log₄ 4 = 0 × 1 = 0

when x = 4

f(x) = log₄ x

f(4) = log₄ 4 = log₄ 4¹ = 1 (log₄ 4) = 1 × 1 = 1

when x = 16

f(x) = log₄ x

f(16) = log₄ 16 = log₄ 4² = 2 (log₄ 4) = 2 × 1 = 2

when x = 64

f(x) = log₄ x

f(64) = log₄ 64 = log₄ 4³ = 3 (log₄ 4) = 3 × 1 = 3

Hope this Helps!!!

         A vertex is a point on a polygon where two rays or line segments meet, the sides, or the edges of the object come together. Vertex is the plural form of vertices.

Response: C

        A node of a graph, or one of the points on which the graph is defined and which may be connected by graph edges, is referred to as a "vertex" in computing.

For instance, a rectangle's four sides result in its four vertices.

   Response:  C . The coordinates are obtained by first subtracting 1 from 4 to obtain 3 and then adding 3 to -2 to obtain 1. (3, 1)

       The vertex is the collective endpoint. Vertex, on the other hand, refers to the common terminal point where two rays converge to make an angle. In a similar manner, we must understand an angle's arm. The term "arm of an angle" refers to the two rays that unite to make an angle.

Answer:

1 comic book costs $4.5

Explanation:

Given that 8 comic books cost $36

To know how much 1 comic book costs, let x be the cost of 1 comic book, then, we have:

8 comic books = $36

1 comic book = x

Then we have the equation

8x = 36

where we can solve for x

Divide both sides by 8

8x/8 = 36/8

x = 4.5

Therefore, 1 comic book costs $4.5

The solution of the linear system of three simultaneous equations is presented as follows; x = 2, y = 1 and z = 4

Simultaneous system of equations consists of a finite set of equations for which a solution to the equation system is required.

The linear system of three equations can be presented as follows;

13•x - 17•y + 16•z = 73...(1)

-11•x + 15•y + 17•z = 61...(2)

46•x + 10•y - 30•z = -18...(3)

The above system of equations can be solved using common multiples of the coefficients as follows;

Multiply equation (2) by 2 and equation (3) by 3 to get;

2 × (-11•x + 15•y + 17•z) = 2 × 61 = 122

3 × (46•x + 10•y - 30•z) = 3 × (-18) = -54

Subtracting equation (4) from equation (5) gives;

138•x + 30•y - 90•z - (-22•x + 30•y + 34•z) = -54 - 122 = -176

138•x - (-22•x) + 30•y - 30•y - 90•z - 34•z = -176

160•x - 124•z = -176

40•x - 31•z = 44

[tex] \displaystyle {z = \frac{(44 + 40\cdot x)}{31}}[/tex]

Plugging in the value of z in equation (1) and (2) gives;

1043•x - 527•y + 704 = 73 × 31 = 2236...(6)

Which gives;

[tex] \displaystyle {y = \frac{(1043\cdot x - 1559)}{527}}[/tex]

339•x + 465•y + 748 = 61 × 31 = 1891...(7)

Which gives; [tex] \displaystyle {y = \frac{(381 - 113\cdot x )}{155}}[/tex] which gives;

[tex] \displaystyle { \frac{(1043\cdot x - 1559)}{527}= \frac{(381 - 113\cdot x )}{155}}[/tex]

Therefore; 221216•x - 442432 = 0

x = 442432 ÷ 221216 = 2

x = 2

y = (1043×2 - 1559)÷527 = 1

y = 1

z = (44 + 40×2) ÷ 31 = 4

z = 4

First let's find the amount Sonia puts in her account each week.

To do so, let's find the amount increased between weeks 5 and 10:

The account increased $25 in 5 weeks, so for each week, we have:

So Sonia puts $5 in her account each week. Now, we need to find the initial value in the account. If after 5 weeks the account has $45, we can subtract $45 by 5 times the amount per week:

So the initial amount is $20.

Now that we have the initial amount and the amount she puts per week, we have the following equation for the amount of money y after x weeks:
