What was unclear about http://www.jiskha.com/display.cgi?id=1386290597 Other than the (7-x)/3 vs 7 - x/3 difference? Just make the fix and show us whatcha got.
looks good to me, though why you bother with the 1x notation is unclear.
since the range is R = (v^2 sin2θ)/g, I get 60^2 * sin(1.094)/16 = 200.0 Looks like you lost a factor of 2 there, since sin2θ = 2sinθcosθ
(2 5 -3) (x y z)T = -1 The transpose is for readability, since it has to be a column vector.
(a) 4log5 = log625 (b) x = ln y (c) 10^x = -3
yes, whether you graph it or not!
negative exponents are in the denominator, so we have 1/(ab^2) 2y/x^3
7th grade mat
PE -> KE mgh = 1/2 mv^2 Note that the mass makes no difference; only the height. gh = 1/2 v^2
we already know that the 1st roll is a 4. So, its odds of being a 4 are 1 1 * 1/6 = 1/6 The odds of rolling a 4 and a 6 are indeed 1/6 * 1/6, but the 4 is not in question. You have a 4 on the table already.
