Justin and jamal are playing a game with fraction tiles. When the bell rings for recess, the boys count their tiles. Justin started with 15 tiles. He lost 6 to Jamal. What fraction of his tiles does Justin have left?
when Yumi turned 17, the fund was worth 11000(1+.055/12)^(12*9) = 18025.08 Now, plug that into your annuity formula, to get annual payments of M = Pr/(1-(1+r)^(-n)) = 18025.08(1-(1.07)^-4) = 4273.83
y'(x) = 3x^2-4x-3 y'(2) = 12-8-3 = 1 But that is exactly the slope of the curve at x=2. Why bother to approximate? I suspect something is missing.
a little synthetic division shows that y = (x-1)(x^2-x-4) use the quadratic formula to get the two irrational roots.
just plug in -2 for x: 2(-2)-3y=5 -4-3y=5 -3y=9 y = -3
I'd say that while it's strictly not possible, it could make sense if you define 100% as the maximum possible effort under normal circumstances. For example, if you went to a strength test facility, and found you could not lift more than 300 lbs, it's still quite p...

you know that x=r cosθ y=r sinθ describes a circle of radius r, with center at (0,0). If the axes are a and b, instead of r, x = a cosθ y = b sinθ If the center is at (h,k) just translate the coordinates: x = a cosθ + h y = b sinθ + k
we know that w*h*5 = 60 2*5*w + 2*5*h + 2*w*h = 94 since w = 12/h, that gives 10(12/h) + 10h + 2(12/h)(h) = 94 120 + 10h^2 + 24h = 94h 10h^2 - 70h + 120 = 0 h^2-7h+12=0 (h-3)(h-4) = 0 h is 3 or 4, so w is 4 or 3 The prism is 3x4x5
Geometry - eh?
things are ambiguous. what does "on the left" of line AB mean? Is AB basically horizontal, and D in on AB toward the left? Or is AB basically vertical and D is not on the line at all, but left of it? #1. how does a point contain B and C? #2. true, since 3 points defi...

any rational zeros have numerators which divide 13 and denominators which divide 169. That means ±(1,13)/±(1,13,169) or, ±1 ±13 ±1/13 ±1/169 A little synthetic division shows that there are no rational roots.
