Answer:

\frac{2\sqrt{6}}{3n^{\frac{3}{2}}}

Step-by-step explanation:

\frac{\sqrt{8}}{\sqrt{3n^3}}==\frac{\sqrt{8}}{\sqrt{3}n\sqrt{n}}=\frac{2\sqrt{2}}{\sqrt{3}n\sqrt{n}}=\frac{2\sqrt{6}}{3n^{\frac{3}{2}}}

Answer and explanation:

Given: Belinda wants to invest $1,000. The table below shows the value of her investment under two different options for three different years:  

Number of years 1 2 3

Option 1 (amount in dollars) 1100 1200 1300

Option 2 (amount in dollars) 1100 1210 1331  

To find:

Part A: What type of function, linear or exponential, can be used to describe the value of the investment after a fixed number of years using option 1 and option 2?  

Part B: Write one function for each option to describe the value of the investment f(n), in dollars, after n years.  

Part C: Will there be any significant difference in the value of Belinda's investment after 20 years if she uses option 2 over option 1?

Solution:

Part A: Linear and exponential functions can be used to describe the value of the investment after a fixed number of years using option 1 and option 2, respectively.  

Part B: (n=n+100) and (n=n+100x) are the functions for each option to describe the value of the investment f(n), in dollars, after n years.  

Part C: Yes, there will be a significant difference of 1900 in the value of Belinda's investment after 20 years if she uses option 2 over option 1.

Part A:

In the case of option 1, the linear function can be used to describe the value of the investment after a fixed number of years. This is because, in option one, the amount increases by a fixed amount every year.

In the case of option 2, the exponential function can be used to describe the value of the investment after a fixed number of years. This is because, in option 2, the amount increase is higher than last year.

Part B:

For option 1, the function is

For option 2, the function is

Here, x is the increase in amount every consecutive year.

Part C:

After 20 years, the amount from option 1 would be 3000 and the amount from option 2 would be 4900. Thus, there is a difference between 1900.

Therefore,

Part A: Linear and exponential functions can be used to describe the value of the investment after a fixed number of years using option 1 and option 2, respectively.  

Part B: (n=n+100) and (n=n+100x) are the functions for each option to describe the value of the investment f(n), in dollars, after n years.  

Part C: Yes, there will be a significant difference of 1900 in the value of Belinda's investment after 20 years if she uses option 2 over option 1.

The length of a certain rectangle is 6 meters more than twice its width. What is the perimeter of the rectangle if the area of t
andreev551 [17]

Answer:

Perimeter = 72 meters

Step-by-step explanation:

Let L be the length and W the width of the rectangle

We have the following relationship

L = 2W + 6

Area of the rectangle = LW = (2W+6)W   by substituting for L

Area =

2W² + 6W =260 ==> 2W² + 6W -260 = 0

Dividing both sides by 2 yields

W² + 3W -130 = 0

This is a quadratic equation which can be solved using the formula for the roots of the equation ie the values of W which satisfy the above equation

However in this case it is easier to solve by factorization

W² + 3W -130  

= W² + 13W - 10W - 130
= W(W + 13) -10(W + 13)

= (W+13)(W-10) = 0

This means W is either -13 or W = 10

Since W cannot be negative, we get W = 10 and

L = 2(10) + 6 = 26

Perimeter of a rectangle is given by

2(L + W) = 2(26 + 10) = 2(36) = 72  Answer

Can someone please help me with this problem ​
Kipish [7]

Answer:

There are 36 possibilities in throwing one green and one red die, eg (G1, R1), (G1, R2), etc; (G2, R1), (G2, R2), etc; etc; (G6, R1), (G6, R2), etc.

In the set of possible numbers from throwing a die, there are only 3 possibilities that sum to to 4: (G1, R3), (G2, R2), (G3, R1).

So the answer is 2.3/36 o

2.One-twelfth.
