Find the magnitude of the
sertanlavr [38]

17.49 is the magnitude of the resultant vector. This can be obtained by adding the vectors and finding magnitude.

<h3>Calculate the magnitude of the resultant vector:</h3>

Resultant vector: vector that gives the combined effect of all the vectors. When we add two or more vectors, the outcome is the resultant vector.

For example,

  • Sum of vector (3,4) and vector (5,7)

(3,4) + (5,7) = (3+5,4+7) = (8,11)

(8,11) is the resultant vector of vector (3,4) and vector (5,7)

Magnitude of a vector: the length of the vector. The magnitude of the vector a is denoted as ∥a∥.

Magnitude of a = (a₁, a₂)

∥a∥=\sqrt{a_{1}^{2} +a_{2}^{2}   }

In the given question,

v (8,10) and w (7, -1)

Adding the vectors,

resultant vector = (8,10) + (7, -1) = (15, 9)

Magnitude of a vector (a,b) = √a²+b²

Here, magnitude = √15²+9² = √225+81 = √306 ≈ 17.49

Hence 17.49 is the magnitude of the resultant vector.

What is the answer for this problem cause i am very confused
EleoNora [17]

41.8, angle y and the measurement angle labeled as just "138.2" are supplementary angles, meaning that when you add them together they equal 180. So all you have to do is subtract 138.2 from 180 and you get your answer which is 41.8.

Identify the median for the data of Johnny’s test scores: 92, 96, 97, 83, 92, 58, 93, 88, 77, 48, 65, 80, 71
Anastasy [175]

Answer

The median is 83

Step-by-step explanation:

You must put the scores in order to find median.

48, 58, 65, 71, 77, 80, 83, 88, 92, 92, 93, 96, 97

Then you find the number that is in the exact middle of the list.

In this case the median (middle number) is 83
