Let vectors Ā = (2,1,-4), B = (-3,0,1), and C = (-1,-1,2).
Aleksandr [31]
<span>Vector Ā * Vector B = -10. This is the scalar dot product and can calculated by taking the magnitude in the x, y, and z of the two vectors and the operation is done. 
The angle </span> Ɵ AB between vector Ā and vector B is 133.635°.
<span>2 Vector B * 3 Vector C = -1. A similar approach is done for this one.</span>

2. 2x + y = -4<br> 5x + 3y = -6
Eduardwww [97]

Answer:

x=15/4,y=-8.25

Step-by-step explanation:

Well to begin with it make both y's equal so multiply the first equation by 3 making it into: 6.6x+3y=-12. next subtract this new equation by the other one making it one equation as, 1.6x=-6, simplify to get: x=15/4, or 3.75 input that into one of the equations the secound one would be easier to make it 18.75+3y=-6 simplify again, 3y=-24.75 than you get y as y=-8.25

Slope intercept form of points 0, -4 and -1, 4
slava [35]

Answer:

y=\frac{0}{-1}  -4

Step-by-step explanation:

first, you have to find the slope, and to do that you use this equation \frac{y2-y1}{x2-x1}

     so, now to insert your points (0,-4), (-1,4)

                                                      (x1,y1)  (x2,y2)

\frac{4-4}{-1-0}  = \frac{0}{-1}

now that you have the slope you can find the y-intercept of the slope-intercept form by looking at your first point (0,-4) and get -4

- if you were to look at this point on a graph it would be on the y-axis therefore, -4 is the y-intercept [if you don't have a point like this one then you can look at a graph with one of your points and make a slope until you are on the y-axis :)]

therefore, the slope-intercept form is y=\frac{0}{-1} -4

[ps, your slope is a zero slope :)]

A fair die is cast four times. Calculate
solmaris [256]

Step-by-step explanation:

<h2>You can solve this using the binomial probability formula.</h2><h2>The fact that "obtaining at least two 6s" requires you to include cases where you would get three and four 6s as well.</h2><h2>Then, we can set the equation as follows:</h2><h2> </h2><h2>P(X≥x) = ∑(k=x to n) C(n k) p^k q^(n-k) </h2><h2>n=4, x=2, k=2</h2><h2>when x=2 (4 2)(1/6)^2(5/6)^4-2 = 0.1157</h2><h2>when x=3 (4 3)(1/6)^3(5/6)^4-3 = 0.0154</h2><h2>when x=4 (4 4)(1/6)^4(5/6)^4-4 = 0.0008</h2><h2>Add them up, and you should get 0.1319 or 13.2% (rounded to the nearest tenth)</h2>
