Answer:
x=4
Step-by-step explanation:
22 = 18 + x
Subtract 18 from each side
22-18 = 18-18 + x
4 =x
The dot product is used to determine the magnitude of the resultant vector of two component vectors. It is expressed as a·b. It does not literally mean that you multiply their values. Instead, you multiply their matrices. However, since we cannot find matrices, let's just find the resultant vector through theorems involving triangles. By cosine law:
R = √[a² + b² - 2abcos(3π/4)]
R = √[60² + 30² - 2*60*30*cos(3π/4)]
R = 83.94
Thus, a·b = 83.94
In each graph, they give you a line.
For part A, they want you to use the <u>Distance Formula</u> which is:

(x2 is supposed to be x sub 2, but I can't put subheadings in the equation tool)
x1, x2, y1, and y2 are the coordinates of the endpoints of the segment.
For part B, they want you to use the <u>Midpoint Formula</u>, which is:

The coordinate pair you get from the Midpoint Formula is your midpoint.
Hope this helps! :)
