Disregarding the force of gravity, the maximum velocity, v, of a rocket is given by vrt In M
where t is the velocity of the exhaust and Mis
the ratio of the mass of the rocket with fuel to its
mass without fuel. A solid propellant rocket has
a maximum velocity is 9.4 kilometers per
second. It has an exhaust velocity of 2.1
kilometers per second. Find its mass ratie M.
(Round your answer to the nearest whole
number.)

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
