Answer:
Its ]-infinity,+infinity[ for both domain and range
Step-by-step explanation:
Given that the octagon rotates 360 degrees, it is a given that for every regular division of the polygon (360/8 = 45 degrees), the image would coincide with the pre-image during the rotation. Therefore, the octagon would coincide a total of 8 times as it rotates 360 degrees about its center.
Answer:
110 Degrees
Step-by-step explanation:
The sum is when different numbers are added.
When all angles are added it adds up to 180 Degrees for any triangle.
Triangles have three sides and two are given as 50 Degrees and 20 Degrees.
There is one angle remaining.
50 Degrees + 20 Degrees = 70 Degrees
Therefore, the last angle must be 110 Degrees. (180-70)
Hello! You can answer this question by using the distributive property. Basically
a(b+c) = a(b) + a(c)
Let's apply it to this expression:
5x(x-4)
=5x(x)-5x(-4)

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
2v + 3v + 75 = 180
<u>Step 2: Solve for </u><em><u>v</u></em>
- Combine like terms: 5v + 75 = 180
- Isolate <em>v</em> term: 5v = 105
- Isolate <em>v</em>: v = 21
