Im having trouble with this:
d1 = (3, -2, 4)d2 = (-5, 2, -1)
Find:
(d1 + d2) . (d1 X 4d2)
d1 and d2 are vectors.
You can tell me the steps for solving this.
Thank you for your time.-d1 + d2 is (-2
1) Which point lies on the region defined by:3x + 2y
A) (3,2)
B) (-1, 5)
C) (0,3)
D) (-1,2)
How do We figure that out? ^^^^^^^^^^^^^^^
2) Where does 5x - 2y = 10 cross the y-axis?
3)What is the
1 6x^2-24/x+2
a 6(x-2)
b 6(x+2)
c 3(x-8)
d 3(x+8)
2 3c+9/3c-9
a -1
b c+3/c-3
c c-3/c+3
d -3
3 k-2/k^2+2k-8
a 1/k-8
b 1/k+4
c 1/k+8
d 1/k-4-1. A
Solution:
(6x^2 -24)/ x+2 = (factor out the six on top p
I tried it myself but i have a feeling I got it wrong :( Here is the formula:
y= -16x^2 + vx + s(plug in 250 for v)(plug in 0 for s)
The find a,b,c values
Plug those values into the quadratric formula
a^2=b^2+c^2-(2bcxcosA)
7^2=8^2+6^2-(2x6x8xcosA)
can someone finish it from there please...
I managed to get it down to 96cosA=63 and had no clue how to finish it.-96 cos A = 63 is NOT correct...show
A chemical manufacturer sells ammonia at a price of 500 dollars per unit. The daily total production cost in dollars for x units is given by 10000+30*x+1/20*x^2, and the daily production capacity is a
I got very messy looking answers when I tried it. My graphing calculators answer was very different from my own.-Im going to start by converting everything to cos, since the derivative will be easier
A. 21^2
B. 6·5·4·3·2·1
C. 6·5·4·3·2
D. 30·12·2

Thanks foe your
the problems go as follows:
in degree mode solve for cosθ=3/7 if 0degrees ≤ θ ≤ 90 degrees.
&
in radian mode solve for sin x = 0.218 if 0 ≤ x ≤ 2(pie)
these are the only two im stuck in bc all the

Im trying to teach myself some calculus this summer so I will be prepared for the course in the fall. Ive taken pre-calculus, and I need a book which will be easy to learn from.-xxxxxxxxxxxxxxxxxxxxxx

Please help me... Thank you...-By Partial Fractions, you can write:
(3x - 4)/(x^2 - 16) = 2/(x + 4) + 1/(x
x^4 + x^3 + 2x - 4
ok i know the answer is (x-1)(x+2)(x^2+2) but i just dont get how you arrive at that, please help me out with some step by step instructions. thanks!-look at the factors and powers
