Answer:
B ⊂ A
Step-by-step explanation:
We know that:
A {x|x is a polygon}
So set A is the set of all polygons.
B {x|x is a triangle}
Set B is the set of all triangles.
First, a polygon is a plane geometrical figure made of a finite sequence of straight segments.
For example, a triangle is a polygon, a rectangle is a polygon, etc.
Then, all triangles are polygons, but not all polygons are triangles.
So we can conclude that the whole set B is included in the set A.
Then the correct notation would be:
B ⊂ A
Answer:
B ⊂ A

A tree is 15 feet tall and casts a shadow of 9 feet. How long is the shadow of a tree 25 feet tall?
Answer:
The shadow is 15 feet long.
Step-by-step explanation:
This is a proportion question. Build a proportion using two fractions.
[tex]\frac{\text{tree height}}{\text{shadow length}}[/tex]
[tex]\frac{15}{9}=\frac{25}{x}[/tex]
"Cross-multiply" -- you might know this as the Means-Extremes Property of Proportions.
[tex]15x=(25)(9)\\15x=225\\x=15[/tex]
Below is the entire graph of function f graph f^-1, the inverse of f
The graph of the inverse of a function is its reflection across the line y = x
Please find attached the required graph created with MS Excel
The graph of the inverse of a function is reflected over the line y = x
In order to graph the function f⁻¹, either the line y = x is drawn and the points of f⁻¹ are traced by taking equal distance from the line y = x, or the x, and y-coordinates of the f are reversed to get the coordinates of f⁻¹ as follows;
The reflection of the point (x, y) across the line y = x is (y, x)
The vertices of the graph of the function f, staring from the top are;
(5, 6), (3, -3), (-3, -5)
Therefore, we have;
The reflection of the point (5, 6) across the line y = x is (6, 5)
The reflection of the point (3, -3) across the line y = x is (-3, 3)
The reflection of the point (-3, -5) across the line y = x is (-5, -3)
The graph of the function f⁻¹ can be plotted using MS Excel, and the above values, as shown in the attached diagram

What number is one hundred more than 770?
Answer:
870 I hope this helps
Step-by-step explanation:
770+100
Answer:
870.
Step-by-step explanation:
We are looking for a new number which is 100 more than 770.
We will get the new number by adding 100 to 770.
We write it down as:
[tex]770 + 100 = 80[/tex]
And finally the solution for: What number is 100 more than 770?
is 870.

Jason begins at the start of a path and rides his bike 11 12 miles on the path. The path is 12 14 miles long. Enter the distance, in miles, Jason must ride to reach the end of the path. Show your work.
Answer:
Number of miles remaining for Jason to reach end of the path = 3/4 miles
Step-by-step explanation:
Total distance of the path = 12 1/4 miles
Distance reached by Jason's bike on the path = 11 1/2 miles
Enter the distance, in miles, Jason must ride to reach the end of the path.
Number of miles remaining for Jason to reach end of the path = Total distance of the path - Distance reached by Jason's bike on the path
= 12 1/4 miles - 11 1/2 miles
= 49/4 - 23/2
= (49-46) / 4
= 3/4 miles
Number of miles remaining for Jason to reach end of the path = 3/4 miles

A(4,10) and B (6,12)
(1) Find the distance between A and B
Answer:
2.8284
Step-by-step explanation:
Input Data :
Point 1(xA,yA)(xA,yA) = (4, 10)
Point 2(xB,yB)(xB,yB) = (6, 12)
Objective :
Find the distance between two given points on a line?
Formula :
Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2
Solution :
Distance between two points = √(6−4)2+(12−10)2(6-4)2+(12-10)2
= √22+2222+22
= √4+44+4
= √88 = 2.8284
Distance between points (4, 10) and (6, 12) is 2.8284
Which is not Equivalent to 3:5
A.30:50
B.21:28
C:15:28

Answer:
B.
Step-by-step explanation:
Since 21 is divided by 3 you might think that it is equivalent but remeber you have to divide by both sides, so if you divide 21 by 7 it works but 28 by seven does not! Hope this helps!
