Consider a mathematical function f() defined over a single variable, denoted as x. The domain of x is any value between negative

infinity and positive infinity. So, basically, everything. The function is parameterized by three constants, a, b, and c. f(x) = x3 + -7.5x2 + -18 x + 7

Answer:

Step-by-step explanation:

To solve this we should use the Euclidean division :

  • Our polynomial function is 16-2x³-6x²+x+9=-2x³-6x²+x+9
  • we should divided by :  4+3x-2=3x+2 and see the rest

Here is a picture with the operation

  • the rest is 47/9 so the number I SHOULD SUBSTACT IS 47/9

Two customers took out home equity loans. • Cathy took out a 10-year loan for $20,000 and paid 5.20% annual simple interest • St
ratelena [41]

Answer: B) $4,000

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

Considering Cathy's loan,

P = $20,000

R = 5.2%

T = 10 years

I = (20000 × 5.2 × 10)/100

I = $10400

Considering Steven's loan,

P = $20,000

R = 4.8%

T = 15 years

I = (20000 × 4.8 × 15)/100

I = $14400

The difference between the amounts of interest Cathy and Steven paid for their loans is

14400 - 10400 = $4000

Monica [59]

Complete question is;

An online store receives customer satisfaction ratings between 0 and 100, inclusive. In the first 10 ratings the store received, the average (arithmetic mean) of the ratings was 75. What is the least value the store can receive for the 11th rating and still be able to have an average of at least 85 for the first 20 ratings?

Answer:

50

Step-by-step explanation:

We are told that In the first 10 ratings the store received arithmetic mean of the ratings = 75.

Thus;

Sum of the first 10 ratings = 75 × 10 = 750

Now, for the mean of the first 20 ratings to be at least 85, it means that the sum of the first 20 ratings would be; 85 × 20 = 1700

Thus, the sum of the next 10 ratings would be; 1700 − 750 = 950.

If maximum rating = 100, then the maximum possible value of the sum of the 12th to 20th ratings is given by;

9 × 100 = 900.

Now, in order to make the store have an average of at least 85 for the first 20 ratings, the least value for the 11th rating is;

950 − 900 = 50
