Answer:

My gain in that year is  - $ 176.5

Step-by-step explanation:

I have $ 1,500 in my investment account. Rate of  interest for a year in my investment account = 8.5 %.

So, the amount of money I am making on my investment in a year,

= $ \frac {1500 \times 8.5}{100}

= $ 127 .5

I owe $ 1600 on a credit card . Rate of  interest a year on this credit card debt,  = 19 % .

So, the money I am paying in interest in a year on my card,

= $ \frac {1600 \times 19}{100}

= $ 304

Since, neither I withdraw money from my investment account  except the interest , nor I pay my whole credit card debt except the interest, so, my gain in that year,

= $ (127.5 - 304)

= - $ 176.5

So, my loss in that year is $ 176.5

I think that you should try to involve yourself in their interests. Find a way to play with them because, as it seems, you want to maintain a friendship with this person, but want to be more involved in their life. I hope this helps <3

What is the complete factorization of the polynomial below?
aksik [14]

Option A: (x+1)(x+3 i)(x-3 i) is the complete factorization of the polynomial x^{3} +x^{2} +9x+9

Explanation:

The polynomial is x^{3} +x^{2} +9x+9

Now, we shall find the complete factorization of the polynomial.

Let us group the common terms, we have,

\left(x^{3}+x^{2}\right)+(9 x+9)

Taking out the common terms,

x^{2} (x+1)+9(x+1)

Factor out x+1 from both the terms, we have,

\left(x^{2}+9\right)(x+1)=0

The term \left(x^{2}+9)\right. can be factored as

\begin{aligned}x^{2}+9 &=0 \\x^{2} &=-9 \\x &=\pm 3 i\end{aligned}  and \begin{aligned}x+1 &=0 \\x &=-1\end{aligned}

Thus, the roots are x=\pm 3 i and x=-1

These roots can be written as (x+1)(x+3 i)(x-3 i)

Thus, the complete factorization of the polynomial is (x+1)(x+3 i)(x-3 i)

A prime number less than 100 is selected randomly. what is the probability that its square has units digit $7$?
liberstina [14]
Any number ends with 0, 1, 2, 3, 4, 5, 6, 7, 8 or  9

Given any number. The square of this number is the last digit of square of the original numbers units digit.

For example

23*23 ends with 9 (3*3=9)

149*149 ends with 1 (9*9=81)

2564*2564 ends with 6 (4*4=16) 

and so on

so all the possible unit digits of a square number are {0, 1, 4, 5, 6, 9}

because:

0*0= 0 ; 1*1=1; 2*2=4; 3*3=9; 4*4=16; 5*5=25, 6*6=36; 7*7=49; 8*8=64, 9*9=81

Thus, the probability that the square of a number selected from any set of numbers being 7, is 0.
