So basically an arithmetic sequence has a common difference, a number which is either added or subtracted at a constant rate (only that number). A geometric sequence is the ratio between two numbers, meaning they are either multiplied or divided by the same number. The sequence would be neither if it follows none of these patterns. So by this logic:
14. Arithmetic, 15. Geometric, 16. Neither, 17. Geometric
Answer:
1. hexagon
2. 4
4. H
5. 6
6-8. count how many sides there are in the shape and multiply the given area to the number of sides you counted. for 6 it's a pentagon. 5 sides. Multiply 8.5 X 5. use calculator for the rest of that section if needed
9-11. they are equilateral triangles. Search up the formula and plug in and solve
Step-by-step explanation:
Answer: 7.2
Step-by-step explanation: Mean= (sum of observations/number of observations)
=(5+6+6+9+10)/5
=(36)/5
=7.2
Answer:
<h3>A reflection across the line x=3, a reflection across the x-axis and a dilation with a scale factor of 2, because each side is double.</h3><h3>
Step-by-step explanation:</h3>
We know that the first transfomration is a rotation 90° clockwise.
Notice that vertex R is at the same horizontal coordinate than vertex C, which means the second transformation must include a reflection across the line x=3, a reflection across the x-axis and a dilation with a scale factor of 2, because each side is double.
