Answer:

R>10 is the required domain.

Step-by-step explanation:

We have been given two squares

Let the larger square area be x

We have been given the area of smaller square we need to find the domain of area of larger square.

Domian is the value that x can take in a function

Here, x is the area of the larger square

Since, area of smaller square is 10cm^2

The area of larger circle has to be greater than 10cm^2

The domain will be all real numbers grater than 10

Mathematically, R>10 is the required domain.

Given that the area can take any positive real number, the larger square hast to be more than 10 cm^2, then the domain for the area of the larger square is all the real numbers greater than 10 cm^2

Isabella saved 2 nickels today. If she doubles the number of nickels she saves each day, how many days, including today, will it
luda_lava [24]

Answer:

Step-by-step explanation:

Alright, lets gets started.

First day, she saves nickels = 2

As we know, she doubles the number of nickels she saves each day.

Means second day she saves nickels = 2*2 = 4

Third day she saves nickels = 2*4 = 8

Fourth day she saves nickels = 2*8=16

Hence we have 2 + 4 + 8 + 16...

It is like a geometric series, the sum of nickels she needs more than 500.

So, lets see how many days she will take to save 500 nickels first

Using the sum formula for geometric series

s=\frac{a(1-r^n)}{(1-r)}

where s is sum, r is multiplication factor, that is 2 in this case and a is first term of series that is 2 also

500=\frac{2(1-2^n)}{(1-2)}

Simplifying, dividing 2 in both sides

250=\frac{(1-2^n)}{(1-2)}

250=\frac{(1-2^n)}{-1}

Cross multiplying

-250=1-2^n

2^n-1=250

2^n=251

Taking log on both sides

nlog2=log251

n=\frac{log251}{log2}=7.971

It means it will take 8 days to save mmore than 500 nickels.   :  Answer

Hope it will help :)

Amala listed her assets and liabilities. Credit Card Balance Car (Paid in full) Jewelry Student Loan Savings Account Stocks $850
MakcuM [25]

Answer:

 Total of Amala’s liabilities is $5500 .

Step-by-step explanation:

Liabilities is defined as  the sums of money which it owes .

As given

Amala listed her assets and liabilities. Credit Card Balance Car (Paid in full) Jewelry Student Loan Savings Account Stocks $850 $2,200 $125 $2,500 $1,200 $1,500 .

As Credit card balance , car (Paid in full) and student loan are Amala liabilities .

Thus

Total amount of Amala’s liabilities = Credit card balance  + car + student loan .

Putting all the values in the above

Total amount of Amala’s liabilities = 850  + 2200 + 2500

                                                         = $5500

Therefore the  total of Amala’s liabilities is $5500 .

Amanda [17]

Answer:

Answer in explanation

Step-by-step explanation:

In this question, we are asked to determine what could have happened if the same experiment carried out by two academicians turned out to five different results statistically.

What majorly could have caused this is the difference in sample size. In a scientific experiment, the term sample size refers to how many individual observations are present.

Due to this difference in sample size, an experiment conducted with more sample size is expected to yield a greater amount of degree of freedom.

Thus, the small differences between the groups of observations are likely to be statistically significant.
