1 * 5 = 5 + 4 = 9
2 * 5 = 10 + 4 = 14
2 * 6 = 12 + 4 = 16
These are some examples of what it is saying you will multiply the number then add for to the sum.

Given that u =< 2,12 >, and z =< -7,5 >
swat32

Using the dot product:

For any vector x, we have

||x|| = √(x • x)

This means that

||w|| = √(w • w)

… = √((u + z) • (u + z))

… = √((u • u) + (u • z) + (z • u) + (z • z))

… = √(||u||² + 2 (u • z) + ||z||²)

We have

u = ⟨2, 12⟩   ⇒   ||u|| = √(2² + 12²) = 2√37

z = ⟨-7, 5⟩   ⇒   ||z|| = √((-7)² + 5²) = √74

u • z = ⟨2, 12⟩ • ⟨-7, 5⟩ = -14 + 60 = 46

and so

||w|| = √((2√37)² + 2•46 + (√74)²)

… = √(4•37 + 2•46 + 74)

… = √314 ≈ 17.720

Alternatively, without mentioning the dot product,

w = u + z = ⟨2, 12⟩ + ⟨-7, 5⟩ = ⟨-5, 17⟩

and so

||w|| = √((-5)² + 17²) = √314 ≈ 17.720

The distance between the points C(-3,1) and D(5,6) is 10.3 units.

<u>Step-by-step explanation:</u>

Let us consider CD is a line segment.

The point C is (-3,1) and D is (5,6).

The Cartesian formula for line is used to find the length between the CD.

Distance between two points = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.

The points are (-3,1) and (5,6).

=\sqrt{(6-(-3))^2+(6-1)^2}.

=\sqrt{(6+3)^2+(6-1)^2}

=\sqrt{9^2+5^2}.

=\sqrt{81+25}.

=\sqrt{106}.

=10.295 ≈ 10.3.

Distance between two points 10.3 units.
