thanks in advance!-A vector, v, perpendicular to a will have the following property:
v · a = 0
If v has coordinates [x, y, z] then:
[x, y, z] · [-3, 6, 2] = 0
-3x + 6y + 2z = 0
Since we only need
A plane is on a bearing 35 degrees south of west at a speed of 400 mph. A wind is blowing in the direction 10 degrees east of south at 60 mph. Find the actual velocity vector of the plane.

Can you guys just check my answers? Thanks.
Suppose the rate at which the volume in a tank decreases is proportional to the square root of the volume present. The tank initially contains 25 gallons,
1. You own 6 cassettes and are taking 4 on vacation. In how many ways can you choose 4 cassettes from 6?
A. 1
B. 720
C. 60
D. 24
2. A single standard six-sided die is rolled. Find the probability
Note that:
(x^2 - 1)^(-1) = 1/(x^2 - 1).
Since x^2 - 1 factors to (x + 1)(x - 1), we can use Partial Fractions to write:
1/(x^2 - 1) = A/(x + 1) + B/(x - 1), for some A and B.
Multiplying both sides
Hi! im really stuck on this question to do with optimisation of constrained functions. I know im meant to use lagrange multipliers method, but i dont know how to start this one of... id really appreci
Three research departments have 8, 7 , 9 andmembers, respectively. If each department is to select a delegate and an alternate to represent the department at a conference, in how many ways can this be
the region is bounded by y = 4 - x^2, the x-axis, and the y-axis.
i tried 512pi/15 and that was wrong.would it be 256pi/15?or something else?-The axis of rotation is horizontal, so the washer method
need help!
Find the inverse of A.
A = the following ...
------ 1 ---- -2 ----- -1
------ 3 ---- -5 ----- -6
----- -1 ----5 ----- -7-set up a matix: [1 2 -11 0 0and use row reduction to get the left
3x(x-4)(x+1)
(3x^2-12x)(x+1)
3x^3+3x^2-12x^2-12x
3x^3-9x^2-12x
This is a cubic polynomial which goes up as x gets bigger-URGENT!Write the polynomial 3x(x-4)(x+1) in standard form.Then classify it by

m = 1/5 or -1--
A step-by-step answer would be awesome! Im studying for an exam >_-Since the denominator factors to x^2(x - 3), split the integrand up into Partial Fractions.
(5x^2 - 10x + 3)/(x^2 - 3x^2) = A/x + B/x
x=t^2+1/(2t) y=4t^(1/2), for 1/sqrt2≤t≤1 about the y axisi know the formula is
