Answer: D.
This is tricky.
Think of the equation as an equation for a line
where in this case.
or
You can see the slope of the graph is which means that for an increase of 1 degree Fahrenheit, the increase is
.
Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of Degrees Fahrenheit
Since Statement 2, is true.
The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:
which is ≠ 1)
An increase of degree Fahrenheit leads to an increase of
not 1 degree, Celsius, and so Statement III is not true.
The final answer is D.

Answer:
The three angles of the triangle given above are 23, 73 and 84 correct to the nearest degree. The concept of dot product under vectors was applied in solving this problem. The three positions forming the triangle were taken as positions vectors. The Dot product also known as scalar product is a very good way of finding the angle between two vectors. ( in this case the sides of the triangle given above). Below is a picture of the step by step procedure of the solution.
Step-by-step explanation:
The first thing to do is to treat the given positions in space as position vectors which gives us room to perform vector manipulations on them. Next we calculate the magnitude of the position vector which is the square root of the sun of the square of the positions of the vectors along the three respective axes). Then we calculate the dot product. After this is calculated the angle can then be found easily using formula for the dot product.
