Which statement describes a situation that can be represented by an exponential function?
A)The value of a stock decreases by 5% every month.
B)customer pays a restaurant bill of $18 and leaves a 20% tip.
C)A canoe rental company charges an initial fee of $12 and an hourly rate of $8.
D)The area of a square increases by 400% when the length of each side of the square increases fro
nits.
Answer: c
Step-by-step explanation:
Using the concept of exponential function, it is found that the correct option is given by:
A)The value of a stock decreases by 5% every month.
-----------------------------
In an exponential function, the rate of change is always a percent of the measure, not fixed, having the model given below, in which the input is the exponent and r is the decay rate, as a decimal:[tex]y(t) = a(1 - r)^t[/tex]
To be a function, it also has to be valid for a domain of the input, not only an one-off occurrence, such as in options B and D.In option C, the rate of change is fixed, of $8, thus, it is linear.Thus, the option that represents an exponential function is:A)The value of a stock decreases by 5% every month.

Can a government that borrows exclusively in its own fiat currency involuntarily go bankrupt (i.e., inability to pay back debt)? Explain your answer.
please help!!
Answer:
If there's one article of faith in Washington (and elsewhere), it's the idea that the United States might get into a debt crisis if it doesn't get its fiscal house in order.
This is not true.
The reason why it's not true is because we live in a fiat currency system, where the United States government can create an infinite number of dollars at no cost to meet its obligations. A Treasury bill is a promise that the government will give you US dollars--something that the United States government can produce infinitely and at no cost.
That's the reason why interest rates on United States debt have only gone down even as the debt has ballooned. That's the reason why Great Britain has very low rates on its debt despite having very high debt-to-GDP. That's the reason why Japan has an astounding debt-to-GDP ratio and still enjoys some of the lowest rates ever. Investors have bet for so long that there would be a run on Japanese debt and have ended up so ruined that in financial circles that trade is called "the Widowmaker". (Here's a more detailed analysis by my former colleague Joe Weisenthal at Business Insider.)
Well, what about Argentina? Argentina had to default on its debt because it had pegged its currency to the US dollar. It wasn't sovereign with regard to its currency since it had to maintain its currency's peg. It wasn't Argentina's debt that caused it to default, it was its currency peg.
What about Greece? Same thing. Greece hasn't used its own currency for ten years. Of course it's going bankrupt.
You don't have to take my word for it. How about Alan Greenspan? He said (PDF): "[A] government cannot become insolvent with respect to obligations in its own currency. A fiat money system, like the ones we have today, can produce such claims without limit."
After all it's already common knowledge among economists, Fed officials, and an increasing number of sophisticated investors.
Maybe so, but it's still not common knowledge among politicians and among the general public. A lot of people still think that the US is under some risk of one day becoming like Greece, and it's distorting our public debate.
It's especially distorting it on the Right, where hysteria about deficits, and debt, and becoming like Greece has reached a fever pitch. Paul Ryan, especially, has framed his entire message on entitlement-cutting on the flawed premise that the US needs to cut its entitlement or it will suffer a debt crisis. This message, in turn, has infected broad swathes of the conservative movement (including very smart people in it), a movement that I consider myself a member of and want to see in strong intellectual health. But very few liberals--certainly no Democratic elected officials that I'm aware of, certainly not the President and the Vice President--are disputing the premise that the US is in any danger of a debt crisis.
In future posts, I will try to look at what the conservative movement can do to move past the idea of the debt crisis, and what it means.

y is directly proportional to (x-1)2.
When x = 3, y = 24.
Find y when x = 6.
Answer:
y = 150
Step-by-step explanation:
Proportions
It's given y is directly proportional to the square of x-1. It can be expressed as:
[tex]y=k(x-1)^2[/tex]
Where k is the constant of proportionality. We know y=24 when x=3. Substituting:
[tex]24=k(3-1)^2[/tex]
[tex]24=k(2)^2=4k[/tex]
Solving for k:
k = 24/4 = 6
Thus, the equation is:
[tex]y=6(x-1)^2[/tex]
When x=6:
[tex]y=6(6-1)^2=6(5)^2=6*25[/tex]
y = 150

In right angled triangle ,
By pythagoras theorem
Hypotenuse ² = Base² + perpendicular ²
Given,
Hypotenuse = 5
Base and perpendicular both are x .
Now,Putting the values
=> (5)² = x² + x²
=> 5 = √2x²
=> 5 = x√2
=> x = 5/√2
Hence,the length of leg is 5/√2.
Verification:
Hypotenuse ² = base ² + perpendicular ²
=> (5)² = ( 5/√2)² + (5/√2)²
=> 25 = 25/2 + 25/2
=> 25 = 50/2
=> 25 × 2 = 50
=> 50 = 50
verified.
If x =3 then y=21 what is the value of x when y=105
Answer:
15
Step-by-step explanation:
21/3=7
x=y/7
so 105/7=x
the answer is 105/7=15
Answer: x = 15
Step-by-step explanation: Proportions.
3/21 = x/105 (cross multiply)105*3 = 21x (simplify)315 = 21x (divide)15 = xWhich is the equation of the line that passes through the points (-4, 8) and (1, 3)?
Answer:
y = − x + 4
Step-by-step explanation:
Use the slope formula and slope-intercept form y = m x + b to find the equation.
y = x - 3
y = -7
solve the system of equations by subtraction
Step-by-step explanation:
[tex]y = \frac{4}{5} x - 3 \\ y = - 7 \\ - 7 = \frac{4}{5} x - 3[/tex]
[tex] - 7 + 3 = \frac{4}{5} x \\ - 4 = \frac{4}{5} x \\ - 20 = 4x \\ x = - 5[/tex]

A 180-degree clockwise rotation about the origin followed by a translation 1 unit to the right
A 180-degree clockwise rotation about the origin followed by a translation 1 unit to the left
A translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin
A translation 1 unit to the right followed by a 270-degree counterclockwise rotation about the origin
Answer:
D
Step-by-step explanation:
I get a paper and trace out the shape and the for line. with the dot. I hold my find on the dot and I counter clockwise to 270 degrees its not directly on the shape so I move it 1 time and it ends up the second shape.
I first thought it was A but then realized that that one said you move it after the 180 tur the the right which would have been incorrect.

A plastic storage bin is shaped like a rectangular prism. The height of the bin is 9 inches. The bottom of the bin has an area of 180 square inches. What is the volume of the storage bin? Enter your answer in the box. in³
Answer:
1620in³
Step-by-step explanation:
Volume of a rectangular prism = BH
B is the Base area
H is the height of the prism.
Given
B = 180in²
H = 9in
get the volume of the prism
Volume of the prism = 180 * 9
Volume of the prism = 1620in³
Hence the volume of the rectangular prism is 1620in³
