___________ is a standard of measure for a physical quantity and is included as part of the x and y axes labels on a line graph.
zlopas [31]

Answer:

Unit of measure

Step-by-step explanation:

Unit of measure

When we construct any type of graph the unit of measure needs to be present, becuase the numbers without units are just numbers and with just the numbers we can't have physical interpretation of the situation.

For this reason is importatn to include the units of meausre with the plots since with that we have a point of reference for the variables used.

And satisfy the condition "A standard of measure for a physical quantity and is included as part of the x and y axes labels on a line graph."

Explain the purposes of inductive and deductive reasoning in mathematics. Be sure to define both inductive reasoning and deducti
uysha [10]
When it comes to deductive reasoning, it is used to reach a logical solution. You start out with the general statement, or hypothesis, and examine all the possibilities so you can reach the final conclusion. 
Inductive reasoning is completely opposite - you focus on specific observations, and then make broad generalizations.

In triangle ABC, a = 9, c = 5, and B = 120°. Find b2.
anygoal [31]

Answer:

(D) b^2=151

Step-by-step explanation:

Given: In triangle ABC, a=9, c=5 and ∠B=120°.

To find: The value of b^2.

solution: It is given that In triangle ABC, a=9, c=5 and ∠B=120°.

Now, using the law of cosines, we get

b^2=a^2+c^2-2(a)(c)cosB

Substituting the given values, we get

b^2=9^2+5^2-2(9)(5)cosB

b^2=81+25-90(\frac{-1}{2})

b^2=81+25+45

b^2=151

which is the required value of b^2.

Therefore, option D is correct.
