45.5 + 15.5x < 175
15.5x < 129.5
x < 8.35
Answer: 8
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).
So the second option is the answer.

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)

Graph the parabola.

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)

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:

Answer:
MN and 170°
Step-by-step explanation:
to get around the red arc you would go alphabetically to the points M, N. since u already have 170° and a circles full rotation is 360° that means 360-170=190 and so the blue arc of the circle would either have to be 190° or 170°, and since the angle of the blue arc is farther than the red arc, that would mean the blue arc is 190°.
