For this case we have the following vector:
 v = (- 8, 2)
 Using product point we have:
 v.v = (-8, 2). (- 8, 2)
 v ^ 2 = (-8) * (- 8) + (2) * (2)
 v ^ 2 = 64 + 4
 v ^ 2 = 68
 v = root (68)
 v = root (4 * 17)
 v = 2 * root (17)
 Answer:
 
v = 2 * root (17)

Alex saved x dollars.
steposvetlana [31]
Answer:
Ethan = 1.(3x)

Step-by-step explanation:
Let's split "Ethan saved 1/3 more than that"
That = x
So, Ethan saved 1/3 more than x
Meaning that Ethan = x + 1/3x
Combine like terms
Ethan = 1 1/3x
which equals to
Ethan = 1.(3x)

Hope this helps :)
Have a great day

Each output value is equal to the square of the input value minus<br> five
Ivenika [448]

i think that A pair of an input value and its corresponding output value is called an ordered pair and can be written as (a, b). In an ordered pair the first number, the input a, corresponds to the horizontal axis and the second number, the output b, corresponds to the vertical axis.

We can thus write our values as ordered pairs

(0, 0) - This ordered pair is also referred to as the origin

(1, 2.5)

(2, 5)

(3, 7.5)

These ordered pairs can then be plotted into a graph.
