ICE Princess25 [194]
The correct ois D. -17.5 degrees
Step-by-step explanation:
The daytime temperature in Apple Valley is
falling by 2.5 degrees each day
Therefore, Change in the temperature each day
=-2.5 degrees
Now, we need to find the net change in the daily
temperature after one calendar week
Now, number of days in one calendar week = 7
So, Net change in the daily temperature after
one calendar week = Daily change × Number of
days in one calendar week
Net change in the daily temperature after
one calendar week =-2.5 x7
# Net change in the daily temperature after
one calendar week =-17.5 degrees
Therefore, The correct option is -17.5
degrees

Express as a single power of 2
den301095 [7]
When you multiply powers, they add, and when you divide them they subtract.
So I would first add the 2^a + 2^b +2^c to get 2^(a+b+c)
Then, divide by 2^(a+b). Because when you divide powers they subtract, you will be taking away the (a+b) from the (a+b+c) and you will be left with c on its own.
The answer is 2^c
