One jet flies at a ground speed of 75 miles per hour faster than another jet. on a particular flight the faster jet requires 3 h
1 answer:
It is a distance-speed-time problem. Applying the general formula of 
, we'll solve this problem. If the speed of the second jet is 
, then the speed of the first jet is 
according to the problem. The first jet requires 3 hours and 36 minutes (3.6 hours) and the second one 3 hours.
By setting up an equation we can write that
and 
The length of flight is
or 
miles
By setting up an equation we can write that
The length of flight is

Answer:
The polynomial function of the lowest degree that has zeroes at -1, 0 and 6 and with a leading coefficient of one is .
Step-by-step explanation:
From Fundamental Theorem of Algebra, we remember that the degree of the polynomials determine the number of roots within. Since we know three roots, then the factorized form of the polynomial function with the lowest degree is:
(1)
Where ,
and
are the roots of the polynomial.
If we know that ,
and
, then the polynomial function in factorized form is:
(2)
And by Algebra we get the standard form of the function:
(3)
The polynomial function of the lowest degree that has zeroes at -1, 0 and 6 and with a leading coefficient of one is .
