Julia used absolute value to find the distance between 0 and 6 on a number line. She then wrote a similar statement to represent
Schach [20]

Answer:

Absolute value function.    

Step-by-step explanation:

  • The absolute value of a number helps us to calculate the distance between a number and zero, provided the direction does not play an important role.
  • The absolute value of a number can never be negative since it is the value of distance.
  • The absolute value function is defined as:

\mid a \mid = a, a > 0\\~~~~~ = -a, a < 0

So, it is correct to write the statement that distance between 0 and 6 is equal to distance between 0 and -6.

\mid 6 \mid = 6\\\mid -6 \mid = -(-6) = 6

If the volume of the expanding cube is increasing at the rate 24 cm3 / min , how fast is its surface area increasing when the su
Georgia [21]

Answer:

16 cm^2/min

Step-by-step explanation:

dV/dt=24

V=a^3, differentiate with respect to t

dV/dt=3a^2*da/dt, a^2*da/dt=8

S=6a^2, 216=6a^2. a=6. da/dt=(8/36)

dS/dt=12*a*da/dt=12*(8/6)=16 cm^2/min
