Answer:
-11°C
Step-by-step explanation:
Original Temp = -2°C
Temp Drop (i.e temperature is reduced by) = 9°C
Final Temperature,
= Original Temp - Temp Drop
= -2°C - 9°C
= -11°C (Ans)
For this case we have the following expression:

Rewriting the expression we have:

Where,
x: exponent to which we must raise the expression to obtain 7 as a result.
We have then:

The exponent must be equal to 1:

Clearing x we have:

Substituting valres:
Answer:
you must raise the expression to 2
Answer:
a. 7 x 2
Step-by-step explanation:
6 5/8 is closer to 7 and 2 1/3 is closer to 2
2/cos x
........................
They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.
