Use polynomial long division to find the quotient and the remainder when 2x^3-3x^2-2x-1 is divided by x-3

Mathematics

Alexxx [7]3 years ago
4 0

Answer:

  • quotient: 2x^2 +3x +7
  • remainder: 20

Step-by-step explanation:

See the attachment.

At each step, the value being subtracted from the dividend is the product of the quotient term and the divisor. The quotient term is found by dividing the highest-degree term of the dividend by the highest degree term of the divisor (x).

When the dividend has a degree that is less than the degree of the divisor, we call that value (20) the remainder.

How should the decimal point in 34.05 be moved to determine the product 34.05×106 ?
r-ruslan [8.4K]

Answer: Six places to the right

Step-by-step explanation:

For this exercise it is important to remember that. by definition, the exponent of a number indicates the number of times you must use the same factor to multiply.

Given:

b^n

"b" is the base and "n" is the exponent.

In this case, you have the following multiplication provided in the exercise:

34.05*10^6

Notice that the base 10 has an exponent 6. This indicates the following:

10^6=10*10*10*10*10*10=1,000,000

By definition, moving the decimal point 6 places to the right (because there are six zeros), is the same as multiplying the decimal number 34.05 by 1,000,000.

  Therefore, based on the explained, when you move the decimal point six places to the right, you get the following product.

34.05*10^6=34,050,000

Two of your friends, Matt and Karen, both run to you to settle a dispute. They were working on a math problem, and got different
Anna11 [10]
So in matt's equation, he made a mistake in the a transision from line 2 to line 3 
in line 2:  -4(-2)2
in line 3: -4(4) 
the mistake is that -2 times 2 is not equal +4 it is equal to -4
also from lines 5 to 6 he made a mistake in order of opperations (mulit division then addition and subtract)
line 5: -10+30/5
line 6: 20/5

so he first subtracted 10 then divided, he should have divided then subtracted
so the equation should have equaled 

Karen used the correct (-) times (+) property and the order of operations
so Karen is correct and Matt is wrong.

Which equations below represent nonlinear functions?
Brilliant_brown [7]
Answer: y = x^2 - 2 does not represent a linear function because the squared exponent above the variable makes that equation quadratic. Quadratic equations look like parabolas on a graph, rather than lines.
