Why is a ray a defined term

Mathematics
1 answer:
Lorico [155]3 years ago

Undefined terms in geometry are point, line, and plane. They are undefined terms because they are concepts and that either their dimensions or thickness can vary.

For example, a point is a location/position in space and it has no dimensions or thickness. In other words, a point has no specific size.

A line extends in both directions to infinity and also has no specific thickness.

All other terms in geometry are called defined terms because they rely on these three undefined terms, so a ray is defined because it uses undefined terms. A ray is defined as a portion of a line that starts at a point and goes to infinity in a particular direction.

the relationship between the relative size of an earthquake, S, and the measure of the earthquake on the Richter scale, R, is gi
omeli [17]

Answer:

Relative Size, S, is 1584.89


Step-by-step explanation:

The equation is R=log_{10}(S)

Where,

  • R is the measurement in Richter Scale
  • S is the relative size of the earthquare

<u>It is given that in Richter Scale, an earthquake measured 3.2, so R=3.2.</u>

<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>

R=log_{10}(S)\\3.2=log_{10}(S)

<em>Converting to exponential form, we have:</em>

3.2=log_{10}(S)\\S=10^{3.2}\\S=1584.8932

<em>Rounding to nearest hundredth, we have:</em>

S=1584.89

Can someone teach me how to do this?
vladimir1956 [14]

the formula is a_{1}+(n-1) d

so a_{1} would be the first number in the sequence, which would be 13 in problem 9.

13+(n-1)d

then you put in n, which is 10 (it represents which number in the sequence you're looking for, for example 16 is the second number in the sequence)

13+(10-1)d

then you find the difference between each number, represented by d which in this case is 3

13+(10-1)3

13+(9)3

13+27=
