Answer:
Letter B would be your answer because 20 feet ABOVE sea level is positve. 20 feet BELOW sea level is negative because you are decreasing from sea level. Then sea level would be zero because it is at its place , there is no measurment because sea level is flat
Step-by-step explanation:
Answer:
- modulus: 3√2
- argument: -3π/4 (or 5π/4)
Step-by-step explanation:
The modulus is the magnitude of the complex number; the argument is its angle (usually in radians).
__
<h3>rectangular form</h3>
The complex number can be cleared from the denominator by multiplying numerator and denominator by its conjugate:

<h3>polar form</h3>
The magnitude of this number is the root of the sum of the squares of the real and imaginary parts:
modulus = √((-3)² +(-3)²) = 3√2
The argument is the arctangent of the ratio of the imaginary part to the real part, taking quadrant into consideration.
arg = arctan(-3/-3) = -3π/4 or 5π/4 . . . . radians
__
modulus∠argument = (3√2)∠(-3π/4)
Answer:
36pi or 113.04
Step-by-step explanation:
V=pi times radius^2 times height
V= pi times 3^2 times 4
V= pi times 9 times 4
V= pi times 36 - ANSWER 1- 36pi
or you can continue...
V= 113.04 (3.14 used as pi)
note(don't forget PEMDAS)
