Answer:
Yes, the given segments will form a triangle
Step-by-step explanation:
Condition: If sum of the measures of any two segments of a triangle is greater than the third segment, then they will form a triangle.
Lengths of the given segments are 18, 12 and 10 units.18 + 12 = 30 > 1012 + 10 = 22 > 1810 + 18 = 28 > 12Here, lengths of the given segments obey the above mentioned condition. So, they will form a triangle.

Calculations ↓Remember , inverse functions do the opposite things in the opposite order.
Here's what happened to x here :
First , it's been multiplied by 7 .Then , 2 has been added to it .We can easily find the inverse of any function by following these steps :
Set the function equal to y as follows :f(x)=7x+2
y=7x+2
2. Now , switch y and x places :
x=7y+2
3. Solve for y .
First , subtract 2 on both sides :
x-2=7y
Divide by 7 on both sides :
[tex]\text{y=$\displaystyle\frac{x-2}{7}$}}[/tex]
We've found the inverse function of f(x)=7x+2.[tex]\tiny\text{hope\:helpful}[/tex]
What is the algebraic rule?? And how do you find out what algebraic rule on a graph is (x,y)to (x,y+10)??? I know how to find basic rules according to the degree rotation but I don’t understand what does + 10 mean how am I supposed to find that on a graph based on rotation degrees???
The teacher never taught me please help me
Thank you!
Answer:
(x, y) ⇒ (-x, y)
Step-by-step explanation:
When you're looking for a rule that transforms one figure to the other, the first step is to look at the figures. You want to identify their orientation (order of vertices) and the relative locations of corresponding vertices.
Here, vertices VWX are in clockwise order. The corresponding vertices V'W'X' are in counterclockwise order. For that to happen, there must be a reflection involved.
The y-axis goes through the midpoints of VV', WW' and XX'. This means the y-axis is the line of reflection. The coordinates of V'W'X' have the same y-values as their originals, but their x-values have changed sign.
The algebraic rule for these two figures is ...
(x, y) ⇒ (-x, y) . . . . . . reflection over y-axis; sign of x changes
__
Additional comment
No rotation is involved here.
The rule (x, y) ⇒ (x, y+10) means the y-coordinate has had 10 added to it. That causes a translation upward by 10 units. This is the algebraic rule.

Answer: [tex]f^-1(1)=-1[/tex]
Step-by-step explanation:
From the graph given we can derive the function [tex]f(x)[/tex]
[tex]f(x) = .5x + 1.5[/tex]
To solve [tex]f^-1(1)[/tex] we need to find the inverse function of [tex]f(x)[/tex].
Inverse functions are functions that essentially "reverse" the mapping of the domain ([tex]x[/tex]) and range ([tex]y[/tex]) of the parent function.
To find the inverse function [tex]f(x)[/tex] we need to solve for x in terms of y.
[tex]y = .5x + 1.5[/tex]
[tex]y - 1.5 = .5x[/tex]
[tex]\frac{y - 1.5}{.5} = \frac{.5x}{.5}[/tex]
[tex]x=2y-3[/tex]
from this, we can derive that
[tex]f(y)^-1=2y-3[/tex]
this can also be written as a function of x
[tex]f(x)^-1 = 2x-3[/tex]
both functions are identical.
take one of these functions and you can find that
[tex]f^-1(1) = 2(1) - 3[/tex]
[tex]f^-1(1) = -1[/tex]
Which graft represent -3x+5y=-15
The graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
-3x + 5y = -15
The above function shows a linear function we can write it as:
5y = 3x - 15
y = (3x - 15)/5
If x = 0, y = -3
x = 1, y = -2.4
x = 2, y = -1.8
x = -1, y = -3.6
x = -2, y = -4.2
Thus, the graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.

Two angles are complementary when they add up to [tex]\tt{90\textdegree}[/tex].
For example:-
Angles whose measures are 60º and 30º are complementary because they add up to 90º.
Now, supplementary angles add up to [tex]\tt{180\textdegree}[/tex].
For example, angles whose measures are 140º and 40º are supplementary because they add up to 180º.

What cosine function represents an amplitude of 2, a period of 2π, a horizontal shift of π, and a vertical shift of −1? (6 points) a f(x) = −1 cos πx + 2 b f(x) = −1 cos (x − π) + 2 c f(x) = 2 cos (x − π) − 1 d f(x) = 2 cos πx − 1
Answer:
c. f(x) = 2 cos(x − π) − 1
Step-by-step explanation:
The amplitude is the multiplier of the cosine function. The vertical shift is a constant added to the cosine function. The horizontal shift is a value subtracted from x in the argument of the cosine function.
For amplitude 2, vertical shift -1, and horizontal shift π, the function will look like ...
f(x) = 2·cos(x -π) -1

Which steps could be part of the process in algebraically solving the system of equations, y + 5x = x + 10 and y = 4x – 10?
Select two options.
y=x2 + 5x + 10
y + 5x = x2 + 10 + 4x - 10
0 = x2-9x 0 = x2 - 9x + 20
One x-value of a solution to the system is 4.
y=x2 + 5x + 10
y + 5x = x2 + 10 + 4x - 10
0 = x2-9x 0 = x2 - 9x + 20

About the Snowflakes
Last winter, I was watching the first snow of the year as it began. As I
was watching, I noticed an interesting pattern: The first minute, only
one snowflake fell. During each passing minute, the number of
snowflakes that fell was equal to the total on the ground plus one.
If this pattern continued for the whole snowstorm, how many
snowflakes fell during the 12th minute? During the 24th minute?
To get 100% on this assignment, you must write a variable
expression that represents how many snowflakes would fall during
the nth minute.
Using a geometric sequence, it is found that:
2048 flakes fell during the 12th minute.8,388,608 flakes fell during the 24th minute.What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
On the first minute, one flake fell. On the second minute, two flakes fell. On the third minute, four flakes fell(3 + 1). On the fourth minute, eight flakes fell(1 + 2 + 4 + 1). Hence the first term and the common ratio of the sequence are given by:
[tex]a_1 = 1, q = 2[/tex].
And the amount of flakes that fell in the minute n is:
[tex]a_n = 2^{n-1}[/tex]
In the 12th minute, the amount is given by:
[tex]a_{12} = 2^{12-1} = 2048[/tex]
In the 24th minute, the amount is given by:
[tex]a_{24} = 2^{24-1} = 8388608[/tex]

The circumference of the ball will be 43.988cm and dividing the circumference by the diameter equals pie.
How to calculate the circumference?The object that's chosen in this scenario is a circular ball. The diameter of the ball is 14cm.
The circumference of the ball will be:
= 2πr
= 2 × 3.142 ×(14/2)
= 2 × 3.142 × 7
= 43.988cm
Dividing the circumference by the diameter will be:
