Answer:

67 $\sqrt{2}$

Step-by-step explanation:

Assuming you require to simplify the expression.

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying the radicals

$\sqrt{72}$ = $\sqrt{36(2)}$ = $\sqrt{36}$ × $\sqrt{2}$ = 6 $\sqrt{2}$

$\sqrt{242}$ = $\sqrt{121(2)}$ = $\sqrt{121}$ × $\sqrt{2}$ = 11 $\sqrt{2}$

Then

2 $\sqrt{72}$ + 5 $\sqrt{242}$

= 2(6 $\sqrt{2}$ ) + 5(11 $\sqrt{2}$ )

= 12 $\sqrt{2}$ + 55 $\sqrt{2}$

= 67 $\sqrt{2}$

What is the component form of the vector represented by 2a when a⃗ =〈−2,3〉?

Paladinen [302]

Answer:

$\vec v = 2\cdot \vec a = \langle -4,6 \rangle$

Step-by-step explanation:

Let $\vec a = \langle -2, 3 \rangle$ , we need to determine $\vec v = 2\cdot \vec a$ , which can be found by applying the following property:

$\alpha \cdot \langle x,y \rangle = \langle \alpha \cdot x, \alpha \cdot y\rangle$ , $\forall \,\alpha,x,y\in \mathbb{R}$ (1)

Then,

$\vec v = 2\cdot \langle -2,3 \rangle$

$\vec v = \langle -4,6 \rangle$
