Which best describe a vector

1 answer:

ANEK [815]4 years ago

6 0

Answer:

Vectors are used to represent physical magnitudes that have an associated address.For example,if we want to represent the displacement of an object,it is not enough to describe only the distance as 10 meters, it is also necessary to describe in which direction the displacement occurred,for example,30°towards the northeast.

Hope this helps:)

What is the volume ,In cubic units ,of Anna’s figure ?

attashe74 [19]

The first column has 10 cubes.

The question states that the other two columns each have 4 fewer cubes than the first column.

10 - 4 = 6

This means that each of the other 2 columns have 6 cubes each.

Column 1: 10 Cubic units

Column 2: 6 Cubic units

Column 3: 6 Cubic units

10 + 6 + 6 = 22

Anna’s Figure has 22 Cubic Units

A triangle has two angles measuring 69 and 77. Determine the measure of the third angle b

igor_vitrenko [27]

Answer:

$m\angle B=34\°$

Step-by-step explanation:

Given measures of 2 angles of a triangle :

m∠A = 69°

m∠C = 79°

Find m∠B.

We know that sum of angles of a triangle =180°

So, we have

$m\angle A+m\angle B+m\angle C=180\°$

Substituting the vales of m∠A = 69° and m∠C = 79°

$69\°+m\angle B+77\°=180\°$

Adding like terms.

$m\angle B+146\°=180\°$

Subtracting both sides by 146°.

$m\angle B+146\°-146\°=180\°-146\°$

∴ $m\angle B=34\°$ (Answer)
