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.

I’ll cylinder has a volume of 132 pi cubic feet and height of 4 feet. What is the area of the base?
iren2701 [21]

The volume formula for a cylinder is V = pi r^2 * h

First we need to find the radius:

132 pi = pi r^2 * 4

r = about 5.74

Then to find the area of the base you use A = pi * r^2

:)))The area of the base is 33 pi square feet
