4. [-16 Points] DETAILS SCALCCC4 3.4.090. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Find the tangent equation to the given curve that passes through the point (10, 10). Note that due to the t2 in the x equation and the t3 in the y equation, the equation in the parameter t has more than one solution. This means that there is a second tangent equation to the given curve that passes through a different point. x = 6t2 + 4...

4. (-/1 Points] DETAILS SESSCALC2 4.1.012.MI. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER When we estimate distances from velocity data, it is sometimes necessary to use times to, ti, tz, tz, ... that are not equally spaced. We can still estimate distances using the time periods At; = t; - t - 1. For example, a space shuttle was launched on a mission, the purpose of which was to install a new motor in a satellite.
