5.09 because 2 is less then 5 so you round down
Answer:
?
(2scos(pi/6) +2i sin(pi/2))^n =-64...n=?
Step-by-step explanation:
2x²(a-b) + x(b-a) + 6(b-a) = 2x²(a-b) - x(a-b) - 6(a-b) = (a-b)(2x²- x - 6)=
=(a-b)(2x+3)(x-2)
6x²(a-b) + x(a-b) + 12(b-a) = 6x²(a-b) + x(a-b) - 12(a-b) =(a-b)(6x²+x - 12)=
=(a-b)(3x - 4)(2x + 3)
Answer:
D
Step-by-step explanation:
To be an identity we require both sides of the equation to equate
A
8x + 9 ≠ 8x - 3 ← not an identity
B
7x - 2 = 8x + 4 - x = 7x + 4 ≠ 7x - 2 ← not an identity
C
11 - (2x + 3) = 11 - 2x - 3 = - 2x + 8 ≠ - 2x - 8 ← not an identity
D
5x + 8 - x = 6x - 2(x - 4), that is
4x + 8 = 6x - 2x + 8 = 4x + 8 ← both sides equate thus an identity
Answer:
Step-by-step explanation:
F=I(1+r)^t
500=225(1.15^t)
t=ln(500/225)/(ln1.15)
t=5.713 years
