Answer:

Step-by-step explanation:

As we know that

      Complex number written as

   Z = x  +  i y

x is the real part (on real axis).

y is the imaginary part(on imaginary axis).

For  (1+i)-(1-i):

Z=   (1+i)-(1-i)

Z = 1 + i - 1 + i

Z=2 i

So x= 0 ,y= 2

For (1+i)(1-i):

Z= (1+i)(1-i) = 1 - i²                         ( i²  = 1)

Z = 1 - (-1) = 2

So x= 2 and y= 0

For  i(2-i)(1+2i):

Z=  i(2-i)(1+2i) = (2 i-  i²) (1+2i)

Z=  (2i + 1) (1+2i)

Z = 2i +1 +4i² + 2i

Z= 4i + 1 - 4

Z= - 3+ 4 i

x = - 3  and y =4

Combine like terms.Put +7 on other side.

-4m= -5-7

-4m= -12

It's -4 times m = -12 right ?

So the answer is m=3 because m= -12/-4

Suppose $24,000 is deposited into an account paying 7.25% interest, which is compoundedcontinuouslyHow much money will be in the
ozzi
Answer:

$49560

Explanations:

The amount deposited is the principal

The principal, P = $24,000

Interest rate, r = 7.25% = 7.25/100 = 0.0725

Time, t = 10 years

Since the interest is compounded continuously, the amounte^ formula is given as:

A\text{ = P}\times\text{e}^{rt}

Substitute P = 24000, r = 0.0725, and t = 10 into the formula above:

\begin{gathered} A\text{ = 24000}\times e^{0.0725(10)} \\ A\text{ = 24000}\times e^{0.725} \\ A\text{ = }24000\text{ }\times\text{ }2.065 \\ A\text{ = }49560 \end{gathered}

$49560 will be in the account after 10 years if no withdrawal or deposit is made
