The function y=3√-x-3 is graphed only over the domain of {x 1-8 ≤x≤ 8).  is the range of the graph is b) {y  : -5 < x < - 1 }

Range is set of Y values for which the function is define.

So, in order to find the range , we need to find the corresponding y values for given domain.

Put x = -8 in  y = ∛-x -3 then we get,

                y = ∛-x -3

                y = ∛-(-8) -3

                y = ∛8 -3

                y = 2 -3

                 y = - 1

Put x = 8 in  y = ∛-x -3 then we get,

                y = ∛-(8) -3

                y = ∛-8 -3

                y = -2 -3

                 y = - 5

Hence the range of function y = ∛-x -3 over the domain of {x : -8 < x < 8 } is

{y  : -5 < x < - 1 }

correct option is b) {y  : -5 < x < - 1 }

Answer:

918.50 in interest over 11 years.

Step-by-step explanation:

Comment

You have to make an assumption here. The assumption is that this is simple interest.

So if the brother pays 10% each year, he is paying

10/100 * 835 each year in interest

10/100 * 835 = 83.50 every year.

There are 11 years, so the total interest paid is 11 * 83.50 = 918.50 dollars in total.. That's more than what he borrowed!

Answer:

(4c + b)(12c - b)

Step-by-step explanation:

- b² + 48c² + 8bc ← rearrange

48c² + 8bc - b² ( split the middle term )

= 48c² + 12bc - 4bc - b² ( factor first/second and third/fourth terms )

= 12c(4c + b) - b(4c + b) ← factor out (4c + b) from each term

= (4c + b)(12c - b)

4y - 7x = 0  is the equation of the line in standard form.

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

To find standard equation of a line we will use points (0,0)  and (80,140)

Lets fine the slope of given data,  slope, m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

m = [tex]\frac{140- 0}{80- 0}[/tex]

m = 140/80

m = 7/4

We can now make the slope intercept form that is y = mx

with the given data,

y = 7/4(x)

4y = 7x

subtract 7x both the side and we get

The scale factor of two suitcases that are similar rectangular prisms is 5/4.

Solids of the same type that have proportional corresponding linear measures are similar solids. In the case of similar rectangular prisms:

length of A / length  of B = width of A / width of B = height of A / height of B

Scale factor refers to the ratio of the corresponding dimensions of similar solids.

If the smaller suitcase is 68 centimeters long and the larger suitcase is 85 centimeters long, then the scale factor is:

scale factor = length of larger suitcase / length of smaller suitcase

Answer:

Step-by-step explanation:

If I name the centre (intersection of diagonals) as O, Angle AOD will be equal to 68°

[Opposite angles are equal]

The diagonals bisect the 4 corner angles of a rectangle in equal halves. So, a = 45°

Also, Angle ADO = 90° - b

[Each of the four angles in a rectangle = 90°]

And In [tex]\triangle[/tex] AOD,

=> Angle AOD + Angle ADO + Angle OAD = 180°

=> 68° + 90° - b + 45° = 180°

=> 203° - b = 180°

=> b = 23°

Vertically Stretching and Compressing

Multiplying a function by positive constant yields a function whose graph is vertically stretched or compressed relative to the original function's graph. If the constant is greater than 1, it will stretch vertically. If the constant is between 0 and 1, vertical compression is done. You get vertical compression.

Vertical compression occurs when you multiply the function by a rational scaling factor. The base of the function graph remains the same even when the graph is compressed vertically. Only initial values ​​are affected.

Solution:

To write the equation of the function y = x with a vertical compression by a factor of 1/4, we will use the formula given below:

y = a · x

This equation means y = a · x, and a is the vertical compression/stretch. Since a = 1/4, we can substitute 1/4 for a.

Therefore, the answer is D, y = 1/4x.

Since the sum of the lengths of any two sides is greater than that of the third side, the set of numbers are the measures of a triangle.

Now we find the type of triangle.

We find the sum of the squares of the two smaller sides, and compare the sum to the square of the largest side.

the sum of the squares of the two smaller sides is,

= 65² + 72²

g(x) = 10x + 20 + 4

g(x + 2) = 10x + 24

2) If g(x) = 10x + 4, then g(x) + g(2) = 10x + 4 + 10(2) + 4

The orientation of the vertices stay same after a reflection.

The orientation of the vertices is nothing but The relative arrangements of points following a transformation or after surrounding a geometric shape are known as orientation. In terms of how the points align, orientation is divided into clockwise and counterclockwise. The points are opposite the original shape when the orientation is reflected. Same orientation denotes that the points are simply a reflection of the original figure and are arranged in exactly the same manner.

The orientation of the vertices stay same after a reflection.

When you translate a figure, you slide it left, right, up, or down. This implies that the coordinates for the vertices of the figure will alter on the coordinate plane.

Apply the same change to each point to graph a.

The variations in a reflection's coordinates can be used to identify it. The figure makes a mirror image of itself when it flips across a line in a reflection. Consider the reflection in the image.
