The average daily high temperature in Madrid peaks at 92°F in the summer and drops as low as 33°F in the winter. The temperature
can be modeled by T (d) = 29.5 cosine (StartFraction 2 pi Over 365 EndFraction (d minus 204) ) + 62.5, where d represents the day number of the year (January 1 is 1, January 2 is 2, and so on). How many days during the year is the high temperature expected to be 75°F or above?

Answer:
C) 131
Step-by-step explanation:
It wants us to find how many days out of the year that the temperature goes above 75 degrees Fahrenheit.
To do this, I set the y value equal to 75 (it should be , but I thought it'd be easier to see this way).
From there, you can easily visualize the days that were above and 75 degrees.
It's just simple subtraction from here:
269-138=131

Answer:

Step-by-step explanation:
A. Reflection across the y-axis replaces each x coordinate with its opposite.
B. Rotation 90° CW does the transformation (x, y) ⇒ (y, -x)
C. This is a translation left 2 units.
D. Rotation 90° CCW does the transformation (x, y) ⇒ (-y, x)
E. This is a translation left 7 and down 2.

In the attached graphs, we have identified a point that is a corresponding point on each figure. This is so you can see how the various transformations move it and the rest of the figure in relation to it. 90° arcs are shown so you can see the rotations more easily.
The figures are labeled and color coded in accordance with the problem statement.
