Answer:
11 hours is the most she can afford
Step-by-step explanation:
The equation is <span>f(x) = 2x5 - 9x4 + 12x3 - 12x2 + 10x - 3 = 0
remark:
the sum of coefficients is = 2-9+12-12+10-3=-7+7=0, so a=1 is a zero of f
f can be written as </span>f(x) = (x-1)Q(x), and f(x) / (x-1)= Q(x)
after euclid's division
Q(x) = 2x4 - 7x3 + 5x2 - 7x +3
so for finding the other roots, making Q(x) for product of factors is a must
Answer:
17
Step-by-step explanation:
1 because it's less than 2
For 3, it is an isosceles triangle and it is an acute triangle.
Armans age : x
Aregs age: y
X = 5y
(15 - 12) = y. They said narek is 12 years older than areg so you deduct 12 years from nareks age which is 15.
So therefore y = 3. So Areg is 3 years old.
Since we know that y = 3
X = 5(3)
X = 15
So therefore Arman is 15 years and Areg is 3 years.
