Amajor league baseball pitcher throws a pitch that follows these parametric equations: x(t) = 142t y(t) = –16t2 + 5t + 5. the time units are seconds and the distance units are feet. the distance between the location of the pitcher and homeplate (where the batter stands) is 60.5 feet. give exact answers, unless instructed otherwise.(d) recall that the speed of the baseball at time t iss(t)=√ [x '(t)]2 + [y ' (t)]2ft/sec. what is the speed of the baseball (in mph) when it passes over mph

Is this a polynomial function? i need to know asap

Use sigma notation to represent the following series for 9 terms.

Examine the paragraph proof. which theorem does it offer proof for? prove jnm – nmi according to the given information in the image. jk | hi while jnm and lnk are vertical angles. jnm and lnk are congruent by the vertical angles theorem. because lnk and nmi are corresponding angles, they are congruent according to the corresponding angles theorem. finally, jnm is congruent to nmi by the transitive property of equality alternate interior angles theorem gorresponding angle theorem vertical angle theorem o same side interior angles theorem
