To find out how much you need when you need a fraction of a number like 1/3 of 9, you can multiply the whole number by the fraction in most cases.

In some cases however, you can convert the whole number into a fraction and then divide it to get the amount in fractional units that you require.

For example:

1/3 of 9

Convert 9 to a fraction.

1/3 / 9/1

1/3 x 9/1 = 3/9

Therefore you would need 3 of 9 for 1/3.

What are the real or imaginary solutions of the polynomial equation x*4-25=0​
Paul [167]

Hello from MrBillDoesMath!

Answer:

Solutions: x = +\- 5i or x = +\- sqrt(5)


Discussion:

Factor x^4 - 25:

x^4 - 25     = (x^2+5) (x^2-5)                              =>  factor x^2 - 5

x^4 - 25 =   (x^2+5)(x + sqrt(5)) (x - sqrt(5))       => factor x^2 + 5

x^4 = 25  = (x +5i)(x-5i) (x + sqrt(5)) (x - sqrt(5))  

Hence the solutions are

x = +\- 5i and x = +\- sqrt(5)



Thank you,


MrB

Graph the data below and then answer the questions that follow. year 1=$20,000, year 2=$21,750, year 3=$23,500, year 4=$25,250,
Mariana [72]

Answer:

Since the difference between the value for each year is constant, this is an arithmetic sequence.

Step-by-step explanation:

Year 2 - Year 1 = 21,750 - 20,000 = 1,750

Year 3 - Year 2 = 23,500 - 21,750 = 1,750

Year 4 - Year 3 = Year 5 - Year 4 = 1,750

Is 1/3 a terminating decimal
Darya [45]
A terminating decimal is a decimal that STOPS, meaning it doesn't go on forever. 

So, we will divide and see. 

1 ÷ 3 = <span>0.3333333............

So NO this is NOT a terminating decimal, but a repeating decimal.

Hope i helped ya!!!!!! </span>
