Place the following temperatures in order from coldest to hottest: -8°C, 10°C, -5°F, 40°F
2 answers:
Answer:
Step-by-step explanation:
It is important to remember these two temperature scales:
- The Fahrenheit Scale (°F).
- The Celsius Scale (°C).
To place the given temperatures in order from coldest to hottest, we can make the conversion from °F to °C. Then:
Knowing this, we can conclude that the order of the given temperatures from coldest to hottest is:

Answer:
Since the angle between the two vectors is not 180 or 0 degrees we can conclude that are not parallel
And the anfle is approximately
Step-by-step explanation:
For this case first we need to calculate the dot product of the vectors, and after this if the dot product is not equal to 0 we can calculate the angle between the two vectors in order to see if there are parallel or not.
a=[1,2,-2], b=[4,0,-3,]
The dot product on this case is:
Since the dot product is not equal to zero then the two vectors are not orthogonal.
Now we can calculate the magnitude of each vector like this:
And finally we can calculate the angle between the vectors like this:
And the angle is given by:
If we replace we got:
Since the angle between the two vectors is not 180 or 0 degrees we can conclude that are not parallel
And the anfle is approximately
