Let's factor the following polynomial to find the roots:
x2-13x + q = 0
Factoring we have:
(x-12.5) * (x + a)
Where,
-12.5 + a = -13
a = -13 + 12.5
a = -0.5
We now look for the coefficient q:
q = -12.5 * a
q = -12.5 * (- 0.5)
q = 6.25
The polynomial will then be:
x2-13x + 6.25 = 0
Its roots are:
x1 = 12.5
x2 = 0.5
Answer:
The other root and the value of the coefficient are:
0.5 and 6.25 (Respectively)
Answer:
Your answer to this question is C (4, -5)
Answer:
25 days
Step-by-step explanation:
If 6 men each work for 5 hours a day: 6 x 5 = 30 hours of work per day
If it takes them 50 days to build the house, then 30 x 50 = 1500 hours work in total to build the house.
If 10 men are working 6 hours a day each: 10 x 6 = 60 hours of work per day.
So 1500 ÷ 60 = 25 days
Therefore, it would take 10 men 25 days to build a house if they were each working 6 hours per day.
0.4 is the first one
0.4 is also the second one
