Answer:

11. 4x^{3}-10x^{2}+6x

Take out 2x ( greatest common factor )
2x(2x^{2}-5x+3)

Factor

2x(2x^{2} -2x-3x+3)

2x(x-1)-3(x-1)=(2x-3)(x-1)

Don't forget about the 2x we took out earlier

Solution to 11: 2x(2x-3)(x-1)

12. 16x^{2} -25y^{2}

This is the difference of squares, so let's use the formula...

a^{2}-b^{2}=(a-b)(a+b)

if, a=16x^{2} and b=25y^{2}

then, the Solution to 12 is:

(4x-5y)(4x+5y)

13. 3x^3-24

First of all, you must find the greatest common factor because there isn't anything else you can do.

3(x^3-8)

Now you can see the difference of cubes...

a^3-b^3=(a-b)(a^2+ab+b^2)

so, the Solution to 13 is:

3(x^3-8)= 3(x-2)(x^2+2x+4)

Three financial institutions, A,B,C, are offering different rates on a loan. Is a offer 3.15 % annual compounded monthly, B offe
coldgirl [10]

Answer:

Step-by-step explanation:

Given that interest rates are as follows:

Let P be 100 dollars for each.

A) 3.15% compounded monthly.

Hence amount = 100(1+\frac{3.15}{1200} )^{12}

Final amount = 103.20 dollars

B) 2.25% compounded quarterly

Final amt. = 100(1+\frac{2.25}{400} )^4

=102.27

C) 2.05% compounded daily

Amount = 100(1+\frac{2.05}{36500} )^{365}

=102.07

Obviously A is the best deal.

Please answer number 3.
Alenkasestr [34]

I can't exactly SHOW you where to put the numbers, but I can teach you the process of how you'd do it.

First off, label your number line from 0-15, as it is the simplest. (You'd be counting by 1 per each line). Then, follow this process:

1) Look at the first digit of your value. Place your number according to your first digit. (So, you'd put 0.365 at the 0 line and 3.521 at the 3 line)

2) Look at the second digit of your value. Imagine that between the two main lines (0-1 and 3-4) that there is 10 smaller lines. Then, you can place your number according to your second digit. (So, you'd put 0.365 at the 0.3 line and 3.521 at the 3.5 line).

3) Look at the third digit of your value. Imagine that between the two smaller lines (0.3-0.4 and 3.5-3.6) that there is 10 smaller lines. Then, you can place your number according to your third digit. (So, you'd put 0.365 at the 0.36 line and 3.521 at the 3.52 line).

4) Look at the fourth digit of your value. Imagine that between the two even smaller lines (0.36-0.37 and 3.52-3.53) that there is 10 smaller lines. Then, you can place your number according to your fourth digit. (So you'd place 0.365 at the 0.365 line and 3.521 at the 3.521 line)

Which equation represents h(x)?
Lelechka [254]

Answer: The second choice: h(x) = (f(x))(g(x))

Step-by-step explanation:

f(x) = -15

g(x) = 15

h(x) = -225

-15 * 15 = -225

Therefore, h(x) is the distribution of f(x) and g(x).
