If x=3+bi, then
You know that 
then
Two possible complex numbers satisfy these conditions:
As you can see the possible value of b is 2.
Answer: correct choice is A.
Answer:
3. x= 20.1
4. x = 22.0
Step-by-step explanation:
SohCahToa. S= sin, C= cos, T=tan.
o = Opposite (the side on the other side of the given angle, also referred to as theta.)
h = Hypotenuse (the side on the other side of the right angle, represented as the square thing.)
a = Adjacent (side next to the given angle.)
3. We have opposite = x, adjacent = 24. We can use tan (Toa.)
tan(40º) = x/24 Multiply both sides times 24.
x = 24*tan(40º) Put into calculator
x = 20.1
4. We have adjacent = 12, hypotenuse = x. We can use cos (Cah.)
cos(57º) = 12/x Multiply both sides by x
x*cos(57º) = 12 Divide by cos(57º)
x = 12/cos(57º) Put into calculator
x = 22.0
Answer:
It will take 4 hours to dig access to the garden.
Step-by-step explanation:
Given that a circular grade has a circumference of 38 yards, and Lars is digging a straight line along the diameter of the garden at a rate of 3 yards, to determine how many hours it will take to dig access to the garden, the following calculation, knowing that the diameter of a circle is equal to the circumference divided by π:
38 / π = X
38 / 3.14 = X
12.09 = X
12.09 / 3 = 4.03
Therefore, it will take 4 hours to dig access to the garden.
Answer: width is 12, length is 16
Step-by-step explanation:
A= l*w
l=w+4
A=w(w+4)
factor
(w+16)(w-12)
w= -16 or w=12
width is 12, length is 16
