Answer: Quadrant I
Step-by-step explanation:
Since the x-axis contains the temperature in C degrees, then the temperature above 0 (meaning positive) would have to be on the right side of the x-axis. And the increase in Y is going upwards. Therefore, positive values for both X and Y are in the first Quadrant
You can show that (y) is proportional to (x) by writing:
This would mean that:
Whereby (k) would be the constant of proportionality.
This value can be an element of a real number.
k∈R
What are real numbers?
Integers, rational numbers and irrational numbers.
Example of a graph which would show that 2 objects are proportional:y=2x
Answer:
1st option is decreased 2nd is increased
Step-by-step explanation:
Because you add a liquid to dilute a solution, it makes the solution weaker (less concentrated) you also added more liquid which would increase the volume
Answer:
rational
Step-by-step explanation:
Using your favorite vector calculator, you can add
.. 250∠30° -150∠(140°-90°)
to get the sum
.. 120.512∠4.804°
Then i(t) = 120.512cos(377t +4.804°) ma
____
The graph shows the individual currents, their sum, and the cosine function above, demonstrating that this is the solution.
