(12-15) Q(x) = 2x^4 - 7x^3 + 6x^2 + x -2
1. Use synthetic division to determine whether (x-1) is a factor of Q(x).
2. Use synthetic division in to find Q(-2)
3. List all of the possible rational roots of Q(x) = 0
4. Find all of the real roots Q(x) =0
Answer:
1) [tex]Q(x)=2x^{4}-7x^{3}+6x^{2} +x-2\\\\=(x-1)^{2}(x-2)(2x+1)\\[/tex]
2) Q(-2) = (-2-1)².(-2-2).(2.-2+1)
= (-3)².(-4).(-3)
= 108
3) Q(x) = 0
=> (x-1)²(x-2)(2x+1) = 0
⇔ x - 1 = 0 or x - 2 = 0 or 2x +1 = 0
4) x-1 = 0 or x - 2 = 0 or 2x + 1 = 0
⇔ x = 1 or x = 2 or x = -1/2

Suppose s varies directly with t. When t27, s=3. What is s when t=632
Answer
567
G
7
H
Answer:
G 7
Step-by-step explanation:
If t= 27 when s=3 27/3=9
the t=63 when s= 7 63/7= 9
Answer:
G
Step-by-step explanation:
Given that s varies directly with t then the equation relating them is
s = kt ← k is the constant of variation
To find k use the condition when t = 27, s = 3 , then
3 = 27k ( divide both sides by 27 )
[tex]\frac{3}{27}[/tex] = k, that is
k = [tex]\frac{1}{9}[/tex]
s = [tex]\frac{1}{9}[/tex] t ← equation of variation
When t = 63, then
s = [tex]\frac{1}{9}[/tex] × 63 = 7 → G

Karina is making accessories for the soccer team. She uses 541.37 inches of fabric on headbands for 40 players and 3 coaches. She also uses 387.20 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer: 22.27 inches.
Step-by-step explanation:
Given : Karina uses 541.37 inches of fabric on headbands for 40 players and 3 coaches.
i.e. 541.37 inches of fabric on headbands used for 43 persons .
Fabric used per person for headband = [tex]\dfrac{541.37}{43}=12.59\text{ inches}[/tex]
She also uses 387.20 inches of fabric on wristbands for only players.
Fabric used per person for wrist band = [tex]\dfrac{387.20}{40}=9.68\text{ inches}[/tex]
Total fabric used for each player = 12.59+9.68 = 22.27 inches.
Hence, 22.27 inches. of fabric was used on a headband and wristband for each player.

Answer:
x = 71
Step-by-step explanation:
Since the 2 legs are congruent ( both 21 ) then the triangle is isosceles.
Thus the base angles are congruent, then
x = [tex]\frac{180-38}{2}[/tex] = [tex]\frac{142}{2}[/tex] = 71
