If a figure is dilated by a factor of 6, the perimeter of the figure will change by a factor of 6.
Step-by-step explanation:
The objects that have the same shape are known as similar figures. Since they are similar in shape it doesn't necessary for those objects to have the same size.
Dilation is the process that enlarges or shrinks the size of an object to its similar figure without changing its size. The Dilation is based on a factor that makes the object to enlarge or shrink.
Since its size has changed so as the perimeter will be changed for both of the figures. The perimeter of an object remains same as the scale factor used to dilate the object.
Consider a square with its side as 2 cm initially and dilated with factor 3.
Perimeter of the square = 4 a. where a is the side.
Then the perimeter of the square will be 8 cm initially.
After dilation the side of the square will be changed as 6.
Then the perimeter will change as 24 cm.
Thus the perimeter of the square initially has increased 3 times after dilation.

The following graph shows a seventh-degree polynomial:
Part 1: List the polynomial’s zeroes with possible multiplicities.
Part 2: Write a possible factored form of the seventh degree function.
Answer:
Part 1:
-5, a multiplicity of 2
-1, a multiplicity of 1
4, a multiplicity of 3
7, a multiplicity of 1
Part 2: [tex]f(x)=(x+5)^2(x+1)(x-4)^3(x-7)[/tex]
Step-by-step explanation:
This question has to be done visually, and can is a little tricky, because depending on the way the graph intercepts the x-axis, there is going to be a different number of roots.
The roots are represented by the intersection of the function with the x-axis.
To start, take a look at the point [tex](-5,0)\\[/tex], which intercepts the x-axis like a parabola(quadratic function). This means that -5 is a "double root" of the function, or it represents two roots of the function.
Now look at the point [tex](-1,0)\\[/tex], which intercepts the x-axis in a linear way, meaning that -1 is simply a "single-root" of the function, or it only represents one root.
So for the next root, look at [tex](4,0)[/tex], which intercepts the x-axis like a cubic function. This means that 4 is is a "triple-root" of the function, and represents 3 roots of the function.
And finally, we have one final interception at [tex](7,0)\\[/tex], and the interception is in a linear form, meaning 7 is simply a "single-root" to the function, or it only represents one root.
So we can conclude that the following are roots with their respective multiplicities
-5, a multiplicity of 2
-1, a multiplicity of 1
4, a multiplicity of 3
7, a multiplicity of 1
And totally, 2+1+3+1 gives us 7, which supports our answer because we know this is a seventh-degree polynomial.(1)
Now for Part 2
We simply take each root, and subtract it from x in our function, then apply our multiplicity as the exponent
So the function would be: [tex]f(x)=(x+5)^2(x+1)(x-4)^3(x-7)[/tex](2)
Hope this helps.

Find the value of x.
Answer:
x = 50°
Step-by-step explanation:
A triangle has total interior of 180 degree .
x + 84° + 46° = 180°
x = 180° -46° -84°
x = 50°
In the given triangle, the value of x is determined to be 50°. In other words, The value of x in the triangle is 50°.
To find the value of x in a triangle with angles measuring 84°, 46°, and x°, follow these steps:
Step 1: Recall that the sum of the angles in a triangle is always 180 degrees.
Therefore, the sum of the three angles in the given triangle is:
[tex]84 + 46 + x = 180[/tex]
Step 2: Combine like terms and isolate x.
Start by subtracting 84 and 46 from both sides of the equation:
[tex]84 + 46 + x - 84 - 46 = 180 - 84 - 46[/tex]
[tex]x = 50^{\circ}[/tex]
Step 3: The value of x is 50. This means that the third angle in the triangle measures 50°.
By applying the fact that the sum of angles in a triangle is 180°, set up an equation and solve for x.
The equation represents the sum of the given angles (84°, 46°, and x°) equating to the total sum of angles in a triangle (180°). By simplifying the equation, obtained x = 50, which indicates that the third angle in the triangle measures 50°.Learn more about triangles here:

What are the domain and range of the function f(x) = -log(5-x)+92
O domain: x <5
range: 129
O domain: x <5
range: (-0.00)
O domain: x29
range:
(-0.00)
domain: 29
range: y29
Answer:
Second Option
Step-by-step explanation:
The argument of the log must be greater than zero so
[tex]5 - x > 0[/tex]
[tex] -x > - 5[/tex]
[tex]x < 5[/tex]
So our domain is All Reals less than 5.
The range of log function is all reals so the answer is -oo, oo).

Graph the parabola.
y=3x²-4
Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function
button.
Answer:
A parabola is a curve with a focus and a directrix. The focus is any point is at an equal distance while the directrix is a fixed line. The vertex of the parabola is (2,1), the two points to the right are (3,4) & (4,13) while the two points to the left are (1,4) & (0,13).
Given that:
y = 3(x - 2)² +1
A parabola is represented as:
y = a (x − h)² + k
Where:
Vertex = (h, k)
So, by comparison; the vertex of the function is:
Vertex = (2, 1)
To plot two points to the right, we select x values greater than 2.
Let: x = 3
So, we have:
y = 3(x - 2)² + 1
y = 3(3 − 2)² + 1
y = 4
Let x = 4
y = 3(x - 2)² + 1

Let x = 4
y = 3(x - 2)² +1
y = 3(4-2)² + 1
y = 13
To plot two points to the left, we select x values less than 2.
Let: x = 1
So, we have:
y = 3(x - 2)² +1
y = 3(1 − 2)² + 1
y = 4
Let x = 0
= 3(x - 2)² + 1 y =
y = 3(02)² +1
= 13
In conclusion:
• The vertex of the parabola is (2,1)
• The two points on the right are (3,4) and (4,13)
• The two points on the left are (1,4) and (0,13)
