Answer:

π/6

Step-by-step explanation:

if tan(pi/16) = squareroot(3)/3

then tan^-1(squareroot(3)/3) = pi/6

Answer:

150˚ or 330˚

Step-by-step explanation:

It is easier to use the calculator, but you can use the unit circle too.

Calculator:

Plug in the equation without the negative, and you get 30˚ which is your reference angle. But since tangent is negative, the angle is in either the second quadrant, or the fourth (because tangent is negative in these quadrants). Now using your reference angle, you can find the answer.

This table shows how many students from two high schools attended a

nalin [4]

Answer:

C. 0.60

Step-by-step explanation:

We need to find out a couple things first:

How many students are from Westville?
How many students did not attend the game that are from Westville?

We need to find specifically Westville, because we don't want to accidentally pick someone from North Beach who attended.

So let's look:

Total from Westville: 150
Total who did not attend from Westville: 90

Now in order to find a probability, we need to divide the smaller number from the biggest number. Let's do that:

90/150 = 0.6

And for this question, we specifically have to round to two decimal places. In order to do this, we just write the extra 0 at the end:

0.6 = 0.60

Look at that, 0.60 is one of our answers! :D

A trucking company uses matrix A , shown below, to represent the driving time in hours for 6 trucking routes. A = [ 4 6 8 ]

zepelin [54]

Each element of the matrix are multiplied by the scalar to form a matrix of

same size as the original matrix in matrix scalar multiplication.

$60 \cdot A = \left[\begin{array}{ccc}240\4&360&480\\360&480&600\end{array}\right]$

Reasons:

The matrix <em>A</em> is presented as follows;

$A = {\left[\begin{array}{ccc}4&6&8\\6&8&10\end{array}\right]}$

Using the multiplication of a matrix and a scalar, we have;

$60 \cdot A = 60 \cdot \left[\begin{array}{ccc}4&6&8\\6&8&10\end{array}\right] = \left[\begin{array}{ccc}60 \times 4&60 \times 6&60 \times 8\\60 \times 6&60 \times 8&60 \times 10\end{array}\right] = \left[\begin{array}{ccc}\mathbf{240}&\mathbf{360}&\mathbf{480}\\\mathbf{360}&\mathbf{480}&\mathbf{600}\end{array}\right]$
