The answer is C) -2 + 8i

You will add the the 3 and -5 together which will be the same as 3 - 5, which equals -2, and add 2i and 6i together, and you will get 8i, so the final answer is -2 + 8i, option choice C

Suppose a triangle has 2 sides of length 3 and 4 and that the angle between these two sides is 60 degrees. what is the length of

shusha [124]

Answer:

$\boxed{b.\:\:\:\sqrt{13}}$

Step-by-step explanation:

Let the third side of the triangle be $h\: units$ .

We can apply the cosine rule to find $h$ .

$h^2=3^2+4^2-2(3)(4)\cos(60\degree)$

We evaluate to obtain;

$\Rightarrow h^2=9+16-24(\frac{1}{2})$

$\Rightarrow h^2=25-12$

$\Rightarrow h^2=13$

We take the positive square root of both sides to obtain;

$\Rightarrow h=\sqrt{13}$

The correct answer is B.

Item 12 What is the shape of the cross section of the cylinder in each situation? Drag and drop the answer into the box to match

Goryan [66]

You can build a cylinder in two ways: either you draw a circle on a plane, and "raise" it perpendicularly to the plane itself, or you start with a rectangle, and rotate it around one of its sides.

For these reasons, if you cut the cylinder with a plane parallel to the base you have a circular cross section, while if you cut the cylinder with a plane perpendicular to the base you have a rectangular cross section.

Some examples of additions with integers with 5 terms or more are:

20 + 1 + 1 + 2 + 1= 25
2 + 1 + 1 + 2 + 1= 7
20 + 2 + 1 + 2 + 1= 26
20 + 1 + 1 + 3 + 1= 26
20 + 1 + 1 + 4 + 1= 27
200 + 1 + 1 + 2 + 1= 205

<h3>What is an Integer?</h3>

In mathematics, an integer is a whole number that is used to represent a value and is not a fraction.

Furthermore, we can make the addition of integers as they would increment based on the number they are being incremented with and this has been shown above.
