What is the end behavior of the following Polynomial ? P(x)=-3x^4+3x-2 *

Mathematics
1 answer:
dangina [55]3 years ago
7 0

Answer:

up, down

Step-by-step explanation:

p(x) =  - 3 {x}^{4}  + 3x - 2

It is an even-degree polynomial. Therefore, the start of domain is the opposite the end of domain.

Meaning if the graph starts by decreasing, the graph will end by increasing.

Because the coefficient of highest degree is in negative. Therefore, the graph starts from negative infinity, increasing. The graph will end in positive infinity but decreasing.

Therefore, the answer is first choice.

How can you write 0.45 as fraction and a percentage ,please show work
Blababa [14]
To convert 0.45 to percent multiply by 100

<span>0.45 × 100 = </span>45 %

<span>Write the decimal number as a fraction
(over 1)
0.45 = 0.45 / 1

Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's

Numerator (N)
N = 0.45 × 10 × 10 = 45
Denominator (D)
D = 1 × 10 × 10 = 100

N / D = 45 / 100

Simplifying our fraction

= 45/100

= 9/20

Lamont retired at age 55 and rolls over $300500
Arlecino [84]

If Lamont withdraws $2,750 monthly, he will be <u>66 years old</u> (after 134.326 months) when the money runs out.

<h3>How is the number of monthly withdrawals calculated?</h3>

We can calculate the number of monthly withdrawals using an online finance calculator.

It determines the number of periods it will take for the investment to be exhausted, given an interest rate of 3.8%.

I/Y (Interest per year) = 3.8%

PV (Present Value) = $300,500

PMT (Periodic Payment) = $-2750

FV (Future Value) = $0

<u>Results</u>:

N = 134.326 months

Years = 11 years (134.326/12)

Age at FV = $0 is 66 years (55 + 11)

Sum of all periodic payments = $-369,397.09 (134.326 x $-2,750)

Total Interest = $68,897.09

Thus, making a monthly withdrawal of $2,750 will exhaust the investment when Lamont turns <u>66</u>.
