Migrating land mammals are often called runners because of the large distances that they can cover in one day. The velocity (speed) of a migrating land mammal or runner in relation to its mass can be modeled by the equation V(m) = 9.31m0.12, where m is the mass of the animal in kilograms and V is the velocity in kilometers per day. Round your answers to the tenths place, if necessary. Part A: Complete the table by determining the velocity of several different runners.

After Dan makes a basket, Josephine claims she can find the amount of time the ball was in the air (from the time it leave's Dan's hand to the time it enters the basket). 10 ft Josephine says she can do this by using Dan's equation ( h (t) = - 16t2 +18t + 8) and setting the equation equal to zero. Dan doesn't think Josephine's thinking is correct. Who do you agree with? Explain your reasoning using mathematical evidence. 0/10000 Word
