Hello from MrBillDoesMath!

Answer:  B

Remark:   It is customary to use x^2,  not x2, to indicate the square of x.


Discussion:

(4x + 3) ^ 2=   ( 4x)^2 + 2 * (4x)(3) + 3^2 =

                       16 x^2 + 24x  + 9


Thank you,

How long will it take to have R30 000 for a trip to Europe if I invest R20 000 now at 15% per year, compounded quarterly?
maw [93]

<span>Compound  interest  formula</span>

A=P(1+ \frac{r}{n} )^{nt}

 

Where

<span>
A= Future value
P = the Principal (the initial amount of money) 
r = annual interest rate</span>

t = time

<span>n= number of times compounded in one t






Remark
----------------------------------------------------------------------------------

r is generally a percentage like 3%, 7% etc and are applied in the formula as 0.03, 0.07..., 

the interest is compounded generally annually (n=1), quarterly (n=4), monthly (n=12), etc...

t is in years,


In our problem:

</span>

A= 30 000

P =20 000

r = 15%=0.15

time = t = ?

n= 4

applying the formula:

A=P(1+ \frac{r}{n} )^{nt}\\\\30,000=20,000(1+ \frac{0.15}{4} )^{4t}\\\\ \displaystyle{\frac{30,000}{20,000} =(1.0375)^{4t}

\displaystyle{ 1.5={(1.0375^4)}^t\\\\

1.5=1.159^t\\\\ \displaystyle { t=log_{1.159}1.5=2.75

The quotient of (x4 + 5x3 – 3x – 15) and a polynomial is (x3 – 3). What is the polynomial?
solmaris [256]

Answer:

Dividend

 =x^4 + 5 x^3 - 3 x - 15

Divisor

=x^3-3

The rule of division of polynomial which is same as division of real numbers states that

Dividend = Divisor × Quotient + Remainder

The division process is shown below.

Quotient = x+5

Remainder =0

Draw a number line and show all numbers that are between 1 and 20 and have exactly 4 factors
True [87]
1 = 1 x 1 
1 factors

2 = 1 x 2
2 factors

3 = 1 x 3
2 factors

4 = 1 x 4
4 = 2 x 2
3 factors

5 = 1 x 5
2 factors

6 = 1 x 6
6 = 2 x 3
4 factors

7 = 1 x 7
2 factors

8 = 1 x 8
8 = 2 x 4
4 factors

9  = 1 x 9
9 = 3 x 3
3 factors

10 = 1 x 10
10 = 2 x 5
4 factors

11 = 1 x 11
2 factors

12 = 1 x 12
12 = 2 x 6
12 = 3 x 4
6 factors

13 = 1 x 13
2 factors

14 = 1 x 14
14 = 2 x 7
4 factors

15 = 1 x 15
15 = 3 x 5
4 factors

16 = 1 x 16
16 = 2 x 8
16 = 4 x 4
5 factors

17 = 1 x 17
2 factors

18 = 1 x 18
18 = 2 x 9
18 = 3 x 6 
6 factors

19 = 1 x 19
2 factors

20 = 1x 20
20 = 2 x10 
20 = 4 x 5
6 factors

So they are 6, 8, 10, 14 and 15 on the number line

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
