(X^3+1)dividend (x-1)
bazaltina [42]

x^3=x\cdot x^2 and x^2(x-1)=x^3-x^2. So we have a remainder of

(x^3+1)-(x^3-x^2)=x^2+1

x^2=x\cdot x and x(x-1)=x^2-x. Subtracting this from the previous remainder gives a new remainder

(x^2+1)-(x^2-x)=x+1

x=x\cdot1 and 1(x-1)=x-1. Subtracting this from the previous remainder gives a new one of

(x+1)-(x-1)=2

and we're done since 2 does not divide x. So we have

\dfrac{x^3+1}{x-1}=x^2+x+1+\dfrac2{x-1}

Mike wants to save $1,750 in the next 12 months. He plans to save $150 each month for the first 11 months.
podryga [215]

Answer:

$1650

Step-by-step explanation:

Based on the question, we don't need the information that Mike wants to save 1750 in 12 months.

We just need to focus on how he is saving 150 every month, for 11 months.

150*11=1650

He will save $1650 if he saves $150 every month for 11 months.

A cell phone tower covers a circular area with a radius of 15 miles. You are at a location that is 11 miles west and 12 miles so
Murljashka [212]

Answer:

No you do not.

This is because we can use Pythagoras Theorem to show that our location sits outside the 15 mile radius of the cell tower.

To work is out you would write the equation

{11}^{2}  +  {12}^{2}  = 265

Then to work out the Hypotheses you would

\sqrt{265}  = 16.2788205961

Which proves that the location is outside of the 15 Mile radius of the cell tower.

It is believed that the average amount of money spent per U.S. household per week on food is about $98, with standard deviation
Makovka662 [10]

Answer:

Test statistic = 2

P-value = 0.0227                                

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = $98

Sample mean, \bar{x} = $100

Sample size, n = 100

Population standard deviation, σ = $10

First, we design the null and the alternate hypothesis

H_{0}: \mu = 98\text{ dollars}\\H_A: \mu > 98\text{ dollars}

Formula:

z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

z_{stat} = \displaystyle\frac{100 - 98}{\frac{10}{\sqrt{100}} } = 2

Now, we can calculate the p-value from the normal table

P-value = 0.0227
