Finding the difference between the two temperatures, it is found that Regina is 38.7ºC degrees colder in January than in July.
----------------------------
- The mid-afternoon temperature in January is of -12.6ºC.
- In July, it is of 26.1ºC.
- The difference of the temperatures is given by:
From the difference of 38.7ºC, there are two interpretations:
- Regina is 38.7ºC degrees colder in January than in July.
- Regina is 38.7ºC degrees warmer in July than in January.

Answer:
She can buy 25 boxes of pasta with $65
Step-by-step explanation:
This question is actually very easy if you forget about all of the unnecessary information. They throw a lot of unnecessary information like they telling you that there are 12 ounces of pasta in each box. You never need that information. My point is that watch out for unnecessary info. Other than that, you can simply multiply 13 (price of 5 boxes) by 5 and get 65. That means that just multiply 5 by 5 and you will see that she can buy 25 boxes of pasta with $65.
If tan theta is -1, we know immediately that theta is in either Quadrant II or Q IV. We need to focus on Q IV due to the restrictions on theta.
Because tan theta is -1, the ray representing theta makes a 45 degree angle with the horiz axis, and a 45 degree angle with the negative vert. axis. Thus the hypotenuse, by the Pythagorean Theorem, tells us that the hyp is sqrt(2).
Thus, the cosine of theta is adj / hyp, or +1 / sqrt(2), or [sqrt(2)]/2
The secant of theta is the reciprocal of that, and thus is
2 sqrt(2)
---------- * ------------ = sqrt(2) (answer)
sqrt(2) sqrt(2)
