Step-by-step explanation:
|...| means absolute value of "...". that means always the "+" value of "...", even if it is negative.
in other words
|-x| = x
|x| = x
|-x - 2y| for x = -2 and y = 3
|- -2 - 2×3| = |2 - 6| = |-4| = 4
The volume of the balloon is 
Explanation:
The radius of the balloon is increasing at a rate of 3 cm/min.
To determine the volume of the balloon when the radius is 14 cm, we shall use the formula 
The rate of change of r with respect to time t is given by,
Now, we shall determine the 
Now, we shall determine the at 
and substituting , we get,
Thus, The volume of the balloon is
The last answer is correct x^5/6 + 2x^7/3
