Determine the miles traveled in 5 hrs at a rate of 189 mi in 3hrs
yes to all 3 questions.
3x^2(x-1) + -3x^3+ 4x^2-2x+1
= 3x^3 - 3x^2 - 3x^3 + 4x^2 - 2x + 1
= x^2 - 2x + 1,
so a + b is a polynomial.
3x^2(x-1) - (-3x^3+ 4x^2-2x+1)
= 3x^3 - 3x^2 + 3x^3 - 4x^2 + 2x - 1
= 6x^3 - 7x^2 + 2x - 1.
so a - b is also a polynomial.
3x^2(x-1)( -3x^3+ 4x^2-2x+1)
= (3x^3 - 3x^2) ( -3x^3 + 4x^2 - 2x + 1)
= -9x^6 + 12x^5 - 6x^4 + 3x^3 + 9x^5 - 12x^4 + 6x^3 - 3x^2
= -9x^6 + 21x^5 - 18x^4 + 9x^3 - 3x^2.
so a * b is a polynomial.
i believe the answer is c because it is the only answer that proves to the survival of a mole
as per the statement:
the path that the object takes as it falls to the ground can be modeled by:
h =-16t^2 + 80t + 300
h is the height of the objects and
t is the time (in seconds)
at t = 0 , h = 300 ft
when the objects hit the ground, h = 0
for a quadratic equation: ax^2+bx+c=0
the solution for the equation is given by:
on comparing the given equation with  we have;
a = -16 ,b = 80 and c = 300
= -2.5 sec and = 7.5 sec
time can't be in negative;
therefore, the time it took the object to hit the ground is 7.5 sec
you take 715 and divide it by 13 to see how long it takes for one hour and you get 55
so then you divide 275 by 55 an dyou get 5
