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,

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

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

a pineapple is 7 times as heavy as an orange. the pineapple also weight 870 grams more than orange what is the total weight in g

Alex Ar [27]

An orange ... o grams = ?
a pineapple ... p = 7 * o
p = 870 grams + o

If you would like to know what is the total weight in grams for the pineapple and orange, you can calculate this using the following steps:

7 * o = 870 + o
7 * o - o = 870
6 * o = 870 /6
o = 870 / 6
o = 145 grams

p = 7 * o = 7 * 145 grams = 1015 grams

Result: A pineapple weights 1015 grams and an orange 145 grams.
