In general, the scalar multiple of k times u, is this:

 $k\vec u = k(ux, uy)=(Kux,Kuy)$

So, here's how we find $3\vec v$

$3\vec v = 3 * (2,4) = (3*2,3*4) 

= (6,12)$

The answer is (6,12).

Answer:

The are a is 6

The length of h = 2.4

Step-by-step explanation:

This is a 3 4 5 special triangle so the length of the hypotenuse is 5

The area for a triangle is calculated by multiplying height to the base and that divided by two

Since it's a right triangle we can take any side length as the height and the result wouldn't change

4×3÷2 = 6 is the area for this triangle now we can use thus information to find the length of h :

h × 5 ÷ 2 = 6

5h = 12

h = 2.4

Step-by-step explanation:

$m \angle DBE = \frac{1}{2} \{m (arc\: AC) + m (arc\: DE) \} \\ \\ = \frac{1}{2} (130 \degree + 40 \degree) \\ \\ = \frac{1}{2} \times 170 \degree \\ \\ \huge \purple{ \boxed{\therefore m \angle DBE = 85\degree}}$
