Answer:

f•g(x) = f(x)•g(x)

f•g(x) = (2x-1) (x²-2x+1)

= 2x³-4x²+2x-x²+2x-1

= 2x³-5x²+4x-1

I really need help!!!
Zigmanuir [339]

Answer:

Pr = 6.67\%

Step-by-step explanation:

Given

n = 10 i.e. 10 people

Required

Probability of being next to each other

First, we calculate the total possible arrangements (without any restriction)

Total = n!

Total = 10!

If the three are to be next to each other,

First, we arrange the three

r_1 = 3!

Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)

The arrangement is:

r_2 =8!

So, the total arrangement, when they have to be next to one another is:

r = r_1 * r_2

r = 3! * 8!

The probability is:

Pr = \frac{r}{n}

Pr = \frac{3! * 8!}{10!}

Expand

Pr = \frac{3*2*1 * 8!}{10*9*8!}

Pr = \frac{3*2*1}{10*9}

Pr = \frac{6}{90}

Pr = 0.0667

Express as percentage

Pr = 0.0667 * 100\%

Pr = 6.67\%

tiny-mole [99]

Answer:

The amount of interest earned after a year is $32.25

Step-by-step explanation:

In this question, we are asked to calculate the amount of interest generated by depositing a sum into an account.

To calculate the interest earned, we use the simple interest formula.

Mathematically;

I = PRT/100

where I is the interest earned

R is the rate which is 6.25% according to the question

T is the time taken which is 1 year

P is the amount of money deposited also know. as the principal which is $516

Plugging these values we have

I = (516 * 6.25 * 1)/100 = $32.25
