Answer:
19/20 of a mile.
Step-by-step explanation:
The common denominator is 20 so we times the first one by 2 the second one by 5 and the last one by 4. (Both numerator and denominator.)
You will end up with this 
Answer:
Step-by-step explanation:
The position equation is given as
and we are looking for the times when the position of the ball is 9 feet. That means that we simply plug in a 9 for s(t) and factor to solve for t:
and
and this is what we factor to find t:
t = .42 sec and then again on its way back down at t = .89 sec
If you multiply the 2’s you get a 4 and when u multiply the zeros with it you would have to add a zero to the 0.002. So it would be 0.0004
For this case we have the following polynomial:
x2 + px-35 = 0
We can factor the polynomial.
Rewriting we have:
(x-7) * (x + a) = 0
The value of a is given by:
-7 * a = -35
a = 35/7
a = 5
Substituting we have:
(x-7) * (x + 5) = 0
Therefore, the value of p is:
p = -7 + 5
p = -2
Answer:
the other root is:
x = -5
The value of the coefficient is:
p = -2
