1000 and a compount interest rate of 9%

1000$, 9% on compount interest.

(2x+3y) = sqr (24*x*y) Solve x in terms of y sorry no oa aviable

(n+1)^3 = - 8 no oa aviable

I think the clou is that 2x/9 >> 2x=9 >> x is 4,5 put the 4,5 in all possible answer you will see that only A) leads to a solution with an integer.

According to the table, if each of the 6 teams in te league played each of the other teams exactly twice and there were no ties, how many games did team X win? (Only 2 teams play a game) Team Number of games won a 4 b 7 c 9 d 2 e 2 x ? 1) 4 2) 5 c) 6 d) 8 e) 10 oa: 3

Of (x^2+6x+9)+6(x+3)+9=0 then x= a: -6 b: -3 c: 0 d: 3 e: 6 oa: a

Only valid for equtitoraial triangle: r = a*b*c / 4K r= radius of the circle a,b,c = side of the the triangle = a^3 k= area of the triangle in this case: first the sides: k = a^2 sqt(3) / 4 9*sqt(3) = a^2* sqt(3) /4 9 = a^2 / 4 a = sqt(4*9) = 6 second the r: r = 6^3 / (9 sqt(3)*4) = 6/ sqt(3) third the area of the circle pi*r^2: = (6/sqt(3))^2 = 36/3 = 12 pi
