The values of ||-10v|| is 51.96 units
- Complex numbers are square roots of negative numbers. They are expressions that consist of both the real and imaginary axis.
- The general form of a complex number is expressed as z = x + iy
Given the complex number v = 6i + 3j,
10v is expressed as 10(6i + 3j)
10(6i + 3j) = 60i + 30j
Take the modulus of the complex number:

Hence the values of ||-10v|| is 51.96 units

Answer:
<u>It would cost about $2.90</u>
Step-by-step explanation:
<em>You have to first see how much inches are in a foot and divide that by how much it costs.</em>
-3(-4y+3)+7y
First multiply -3 by the terms in the parentheses
-3(-4y+3) = 12y -9
Your expression now looks like
12y -9 +7y
Then combine the terms containing the variable y
12y + 7y = 19 y
Your final answer is
19y - 9 (answer choice A)
