Determine whether the vectors u and v are parallel, orthogonal, or neither.
kodGreya [7K]
<h3>Answer:  orthogonal </h3>

===========================================================

Explanation:

For any two vectors defined as follows

u = <a,b>

v = <c,d>

the dot product is computed by

u dot v = a*c + b*d

If the dot product of the vectors is 0, then the vectors are orthogonal. Meaning they are perpendicular to one another.

-------------------

Let's find the dot product of these two given vectors

u = < 2, -4 >

v = < 6, 3 >

u dot v = 2*6 + (-4)*3

u dot v = 12 - 12

u dot v = 0

Therefore, these two vectors form a right angle and are <u>orthogonal</u>

-------------------

Extra info:

If we can show that u = <a, b> and v = <ka, kb> for some real number k, then we have shown that vectors u and v are parallel.

Global Gas International offers to contract the Halidurton Heavy Construction Corporation to build an oil pipeline from Canada t
LenKa [72]

Answer:

probability that make risk neutral accepting project < \frac{1}{3} or 33.33 %

Step-by-step explanation:

given data

income = $600 million

legal liability = ​$1,200 million

to find out

what is the theta such that it is indifferent between accepting and rejecting the​ contract

solution

we know here that risk neutral between accept and reject contract   θ value will be as that when net present value NPV of contract = 0

so

we can say NPV > 0

so ( 1- θ )  $600 Million + θ ( $1200 Million)  > 0

$600 Million > $1800 θ

θ < \frac{1}{3} = 33.33 %

so probability that make risk neutral accepting project < \frac{1}{3} or 33.33 %
