4 miles east,  7 miles southeast,  6 miles south  1 mile southwest  3 miles east A plane flies 1200 km in 2.5 hours. What is the average speed of the flight?

The answer choices are  A) 480 km/hr  B) 300 km/hr C) 1200 km/hr D) 200 km/hr C-(-4,2,4). Find the distance between the point (x,y,z) and C.

I had tried the points (0,0,0)-(-4,2,4) and then use the distance formula, but that has not worked. Then I tried (1,1,1), but that also did not work. I am lost. Any help is needed. Find the length of ->OR.

(We are talking about vectors.   R = (4, 5, 5).   Then it has,   ||->OR|| = _____.   I'm not sure how you find OR if you do not have what O is... Find the equation of a sphere if one of it's diameters has endpoints (-10,0,-6) and (4, 14, 8).

I have written:   (x+3)2+(y-7)2+(z-1)2-sqrt(588)/2 = 0. But it is marked incorrect.

I had put the equation as:   (x-5)^2+(y-3)^2+(z+6)^2   However it was viewed as incorrect. Also they had that it equaled zero.   equation input =... Simple(?) Vector Problem

A river flows northward with a velocity of 3 km/hr. A man rows a boat eastward with a velocity 4 km/hr relative to the water. The river is 1 km wide. a) find his speed and direction relative... Vector v has its initial point at (7, -9) and its terminal point at (-17, 4).

Vector v has its initial point at (7, -9) and its terminal point at (-17, 4). Which unit vector is in the same direction as v? The normal to the plane is given by (5,-3,1). There are two lines with direction vectors (2,3,-1) and (1,2,1) which is skew to each other, but is parallel and both equidistant from the plane. What... Let v be the vector (3 over p), such that |v| = 17. Calculate all possible values of p.

Let v be the vector (3 over p), such that |v| = 17. Calculate all possible values of p.   * (3 over p) - I wrote it this way because the 3 is actually positioned above the p. I need... If vector u is <3,4> and vector b is also <3,4>, then is vector a parallel to b or is it equal to it

I am honestly confused on if 2 vectors have the same change in x and y values then is it parallel or equal to it. And for example if 1 vector is double the other then how are they parallel, whywo...

What is the answer to the question and how do we do it
