Use synthetic division to solve (x^4 – 1) ÷ (x – 1). What is the quotient?

Answers

Answer 1
Answer:

Answer:  x^3+x^2+x+1

Step-by-step explanation:

Here, the dividend is x^4+0x^3+0x^2+0x-1

While divisor is  x - 1

In the synthetic division,

We will follow the following steps,

Step 1) Write the coefficient of the dividend in the decreasing order of degree,

Hence, the element in the first row under the division sign are 1, 0, 0, 0, - 1

Step 2) By putting x - 1= 0, we get x = 1

Hence, write down 1 outside the sign,

Here the problem is set up correctly, So, bring the leading coefficient (first number) straight down.

Step 3)  Multiply the number in the division box with the number that we brought down and put the result in the next column. Then, Add the two numbers together and write the result in the bottom of the row.

Step 4) Repeat the third step until you get the last element ( here the last element is 0,

Thus, We get numbers in the third row, 1, 1, 1, 1 ( Except 0 )

⇒ Quotient is  x^3 + x^2 + x + 1

The value of a car depreciates by 18% per year. Work out the current value of a car bought 4 years ago for £20000

Answers

Given:
depreciation rate: 18%
Value of the car : 20,000
Age of the car : 4 years.

The depreciation is based on the current value of the car. Therefore, the amount of depreciation varies.

yr   Beginning Value   Dep. Rate    Depreciation      Ending Value
1   20,000.00                 18%             3,600.00          16,400.00
2   16,400.00                 18%             2,952.00          13,448.00
3   13,448.00                 18%             2,420.64          11,027.36
4   11,027.36                 18%             1,984.92            9,042.44

The current value of a car bought 4 years ago is 9,042.44

Beginning value : purchased amount on 1st year. then, ending balance of the previous year from 2nd year onwards.
Depreciation : Beginning value * depreciation rate
Ending value : Beginning value - depreciation

20000 = 100%18 x 4 = 72%20000 / 100 = 200200 = 1%200 x 72 = 14,40020000 - 14,400 = 5600The value of it now should be £5600

Answer:

We know that range is the set of outputs that shown on the y-axis of the graph, so we must find the endpoints of the graph on the y-axis. When we look, we get the endpoints -6 and 10, so we know that this is the range, and so we represent this in an expression:

-6 < y < 10
