The volume of a spherical balloon starts at 10m3 , and is increased at 1m3/minute. Find a formula for the rate of change of the radius of the sphere in terms of time t. Your answer should only involve the variable t, and constants, not any other variables.

The graph of the function f(x) = (x + 2)(x + 6) is shown below. which statement about the function is true? the function is positive for all real values of x where x > –4. the function is negative for all real values of x where –6 < x < –2. the function is positive for all real values of x where x < –6 or x > –3. the function is negative for all real values of x where x < –2.
