Use the formulla d=rt. find t for r =48.3m/h and d=545.79m.

If you solve d = rt for t, you have t = d/r.  If we have values for d and r we will fill them into that equation and divide.  .  Setting that up so the meters cancel as they should looks like this: lets us divide as we need to and at the same time cancel out the distance, leaving us time in hours.  The t value then is 11.3 hours.

0.69 yards

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
