Identify the domain and range for the table from problem #5 of your assignment. Also, determine if it represents a function.

Lana71 [14]

Answer:

Domain: {4,5,7,10}

Range: {2,4,8}

Not a function

Step-by-step explanation:

The domain is all the x-values.

The range is all the y-values.

However, this isn't a function because two different inputs have the same output. If it were a function, there would be one unique output for every input.

In the right triangle ABC shown, c=17ft and angle A=30 degrees Determine side a

jekas [21]

Using relations in a right triangle, considering c as the hypotenuse, we have that the length of side A is: $a = 8.5\sqrt{3}$

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.

The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.

The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

From the information given, we can build the following relation:

cos(A) = a/c.

$\frac{\sqrt{3}}{2} = \frac{a}{17}$

$a = \frac{17\sqrt{3}}{2}$

$a = 8.5\sqrt{3}$

HELP!!!!!!!!! I’m almost done

balandron [24]

Alright, we're in the home stretch here :) All you need to remember is that i² = -1. Otherwise, it is the same as FOIL

(3-2i)(1+7i)

3-2i+21i-14i² ← Replace the i² with -1, then simplify like numbers

3+19i+14

17+19i or C
