Answer:

u\cdot v=32

Step-by-step explanation:

Assuming u and v are vectors, their dot product is u\cdot v where u_1v_1 + u_2v_2:

u\cdot v=u_1v_1+u_2v_2=(2)(8)+(-8)(-2)=16+16=32

Therefore, u\cdot v=32

The axis of the sphere below is 16 units in length. What is the surface area of the sphere?.
Nataly_w [17]
There are enough information's already given in the question. Based on those information's that answer can be easily deduced.
Radius of the sphere = 8 units
Then
Surface area of the sphere = 4 *pi * r^2
                                            = 4 * pi * (8)^2
                                            = 4 * pi * 64
                                            = 256pi
I hope that this answer has come to your help.

A line segment is defined by which of the following statements?
kaheart [24]

The only given option that correctly defines a line segment is;

<u><em>Option C; All points between and including two given points.</em></u>

      In geometry in mathematics, a line segment is defined as a part of a line that is bounded by two distinct end points.

Now, let us look at the options;

Option A; This is not correct because a line segment must have 2 distinct endpoints

Option B; This is not correct because a line segment is a part of a line and not a set of points.

Option C; This is correct because it tallies with our definition of line segment.

Option D; This is not correct because a line segment does not extend infinitely.
