divide both sides by 0.5
x=0.5 hr
It will take 0.5 hours to paint one wall
Answer:
The possible values are less than 4 but greater than –4
Step-by-step explanation:
If the absolute value of integer number is less than 4 then it is 0, 1, 2 or 3.
so the possible integer numbers are: -3, -2, -1, 0, 1, 2 or 3.
All of them are greater than -4 and less than 4
Let
The exponent is indeed 
- not a typo!
Take the antiderivative of 
, denoted by 
. This recovers a factor of 
in the denominator, which lets us condense it to a single factorial.
Recall the series expansion of sine,
Then with a little algebraic manipulation, we get
Differentiate to recover .
Finally, 
, so our sum is
The answer is D. The volume of the rectangle = 180 x 1/3 x 1/3 x 1/3 = 180/27=6 + 18/27.
