Answer:
$7.80
Step-by-step explanation:
Multiply 0.4 (that is 40%) by 13
It would be 5.2
So subtract 5.2 from $13.00
7.8
So the CD price would be $7.80 with a 40% discount
Hope this helps you :)

Step-by-step explanation:
-2 x 11 = -22
I think the equation is still the same as a non-right triangle. a=(w*l)/2
As long as it's a triangle, that would be the equation. This is because for finding the area for a square or rectangle (quadrilateral) is always a=w*l, that means that the equation for any triangle is always a=(w*l)/2. The division by 2 for the triangle's equation is there because a triangle is half of a quadrilateral. So you would have to divide the quadrilateral's equation by two. Hope I helped :)

Divide by 2 to get 1/3 of the week:
1/4 / 2 = 1/8
Multiply by 3 to get the full week:
1/8 x 3 = 3/8
Thus your answer is B. 3/8
Have A Nice Day ❤

Answer:
1
Step-by-step explanation:
You want to know the value of i^4.
<h3>Powers of i</h3>
The fourth power of i, √(-1), can be found the same way the value of any fourth power can be found: carry out the multiplication.
i^4 = i·i·i·i = -1·i·i = -i·i = -(-1) = 1
The fourth power of i is 1.

<em>Additional comment</em>
As you can see from the evaluation process, ...
i¹ = i
i² = -1 . . . . . definition of i
i³ = -i
i⁴ = 1
The sequence repeats for higher powers.
