Answer: the correct option is
(D) The imaginary part is zero.
Step-by-step explanation: Given that neither a nor b are equal to zero.
We are to select the correct statement that accurately describes the following product :
We will be using the following formula :
From product (i), we get
![P\\\\=(a+bi)(a-bi)\\\\=a^2-(bi)^2\\\\=a^2-b^2i^2\\\\=a^2-b^2\times (-1)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{since }i^2=-1]\\\\=a^2+b^2.](https://tex.z-dn.net/?f=P%5C%5C%5C%5C%3D%28a%2Bbi%29%28a-bi%29%5C%5C%5C%5C%3Da%5E2-%28bi%29%5E2%5C%5C%5C%5C%3Da%5E2-b%5E2i%5E2%5C%5C%5C%5C%3Da%5E2-b%5E2%5Ctimes%20%28-1%29~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~%5B%5Ctextup%7Bsince%20%7Di%5E2%3D-1%5D%5C%5C%5C%5C%3Da%5E2%2Bb%5E2.)
So, there is no imaginary part in the given product.
Thus, the correct option is
(D) The imaginary part is zero.
Answer:
A balloon rose 32 feet in the air then it fell down to the ground
Step-by-step explanation:
Tom is spending more on tax totaling 23.54
while his cousin is only spending 18.72
How to get tax with percent take base price ex:22+ 7%
transform percent into a decimal : .07
now multiply the decimal times base price : 22x0.07
tax is a $1.54 now add that to your base price 22
and you get your total $23.54
To find 33% of 1.45 we have to tranform 33% into decimal of traction
33% is 0.33 or
and multiply if by 1.45
so
0.33*1.45=0.4785
or
1.45*
Since you are subtracting 2 logs, you write the single log as a quotient.
