Answer:
Li Jing's formula i.e.
is right.
Step-by-step explanation:
Considering the sequence

A geometric sequence has a constant ratio r and is defined by





So, the sequence is geometric.
as



so



Therefore, Li Jing's formula i.e.
is right.
Answer:
So ofc it's third
Step-by-step explanation:
You'll need to use the Pythagorean theorem:
a²+b²=c²
36² + 15² = c²
1296 + 225 = c²
1521 = c²
= 39
Answer:
1. right triangle - a triangle with one angle that measures 90 degrees
2.radius- a line segment from the center of a circle to any point on the circle
3. ray- a part of a line that has 1 endpoint that goes in one direction forever
4. rotational symmetry- a property that allows a figure to be rotated less than 360 degrees and still look the same
5. regular polygon- a polygon whose sides are all the same lengths and whose angles are the same measure
6. reflection- a transformation in which a figure is flipped across a line to give a mirror image of the original figure
Step-by-step explanation:
The anwser is 17 and 3. 17+3=20, and the difference is 14!
