You are given 3 different investment scenarios to choose. Answer questions 13 below. Option​ 1: Invest​ $20 and the balance is doubled each day. Option​ 2: Invest​ $0.20 and the balance is tripled each day. Option​ 3: Invest​ $0.01 and the balance is quadrupled each day.

The payments each month do not cover all interest and no principal. The correct answer would be an option (B).

A credit card trap occurs when the minimum payments required each month do not cover all the interest charges and do not reduce the principal balance. This means that even if the cardholder makes the minimum payments on time, they will still be paying only the interest charges and not reducing the amount of debt. This can result in a cycle of high-interest debt that is difficult to escape from.

Option A is incorrect as it's describing a common way payments work on credit cards.

Option C is not a trap, as it's describing a credit card issuer with a low-interest rate.

Option D is also incorrect, as it's describing a common way payments work on credit cards.

Hence, the correct answer would be an option (B).

Answer: Simplified

Step-by-step explanation: The question is already as simplified as it can get.

The distance between the two cities located at latitude 19 degrees N, and the other has a latitude 26 degrees S is 5011 km

The distance between the two cities is calculated using the formula

= x/360 * 2 * pi * r

where

r = radius

x = the angle subtended by the distance

From the question we have that

x = 19 degrees N + 26 degrees S

x = 45 degrees

radius of the earth = 6380 km

distance between the points = x/360 * 2 * pi * r

distance between the points = 45/360 * 2 * pi * 6380

distance between the points = 0.125 * 12760 * pi

distance between the points = 5010.84 km

The estimated value of y when x1=12, x2=1, and x3=-1 is -204. This is calculated by substituting the given values into the equation ˆy=−184−7x1+47x2+20x3.

ˆy=−184−7(12)+47(1)+20(-1)

ˆy=−184-84+47-20

ˆy=−204

In the multiple regression equation

ˆy=−184−7x1+47x2+20x3

the estimated value of y can be determined by substituting the given values of x1, x2, and x3 into the equation. For example, given

x1=12, x2=1, and x3=-1,

the estimated value of y can be calculated as follows: ˆy=−184−7(12)+47(1)+20(-1). This simplifies to

ˆy=−184-84+47-20, or ˆy=-204.

The equation takes the form of a linear equation, with each independent variable x1, x2, and x3 multiplied by a coefficient, and then added together to give the estimated value of y. In this example, the coefficient for x1 is -7, for x2 is 47, and for x3 is 20. This means that if x1 increases by 1 unit, then the estimated value of y will decrease by 7 units; if x2 increases by 1 unit, then the estimated value of y will increase by 47 units; and if x3 increases by 1 unit, then the estimated value of y will increase by 20 units. Using the multiple regression equation, therefore, the estimated value of y can be calculated when the values of the independent variables are known. In this example, given x1=12, x2=1, and x3=-1, the estimated value of y is -204.

The rate of change of the amount of gasoline in a storage tank at t=3 hours is -0.75 thousand gallons per hour, and the amount of gasoline in the storage tank is increasing at an increasing rate between t=5 and t=10.

(a) To estimate the rate of change of the amount of gasoline in the storage tank at time t=3 hours, we can use the formula for the average rate of change over an interval: (G(b) - G(a)) / (b - a).

We can choose two points on the table that are closest to t=3 hours, such as t=2 and t=4. Using these points, we have:

G(2) = 22

G(4) = 20.5

Substituting these values into the formula, we get:

(G(4) - G(2)) / (4 - 2) = (20.5 - 22) / (4 - 2) = -1.5 / 2 = -0.75

The units of measure for this rate of change would be thousands of gallons per hour.

(b) Since G′′(t)>0 for 5≤t<10, this means that the second derivative of G(t) is positive for all values of t within this interval. The second derivative represents the rate of change of the rate of change, or the acceleration. A positive second derivative indicates that the rate of change is increasing, or that the function is accelerating. This means that the amount of gasoline in the storage tank is increasing at an increasing rate between t=5 and t=10.

We can also conclude that G′(t)>0 for 5≤t<10 since the second derivative represents the rate of change of the first derivative, which is positive. This means that the first derivative, or the rate of change of the function, is also positive for this interval. This confirms that the amount of gasoline in the storage tank is increasing between t=5 and t=10.

Complete Question:

'A gasoline storage tank is filled by a pipeline from a refinery. At the same time, gasoline flows from the tank into trucks that will make deliveries to gasoline stations.

The solution to the system of equations is x = 0, y = 0.

What is substitution algebraic expression?

Substitution means replacing the variables in an algebraic expression with their numerical values. We can then work out the total value of the expression.

To use algebraic substitution to solve for x and y, we can substitute one equation into the other and solve for one of the variables.

Given that y = -8x, we can substitute this into the second equation, 2x + 4y = 0

So, 2x + 4(-8x) = 0

Simplifying this we get,

2x - 32x = 0

30x = 0

Dividing both sides by 30

x = 0

Now we have x = 0, we can substitute this value back into the equation y = -8x

So y = -8(0)

y = 0

No, we cannot draw a triangle with sides 3 cm, 3.5 cm, and 6.5 cm.

Let's understand the concept behind this:

Apply the triangle's length-of-sides property, which stipulates that the total of any two sides should be more than the value of the third side. Such a triangle cannot exist if there is any pair of sides whose sum is equal to or less than the third side.

We must determine whether the supplied side lengths constitute a triangle. We now understand that the triangle's third side should be greater than the sum of any two of its sides. Such a triangle cannot exist if there is any pair of sides whose sum is equal to or less than the third side. So, we'll try every combination and see if it meets the criteria.

Let’s assume AB = 3 cm, BC = 3.5 cm and AC = 6.5 cm.

AB + AC = 3 + 6.5 cm = 9.5 cm > 3.5 cm = BC.

AC + BC = 6.5 + 3.5 = 10 cm > 3 cm = AB.

AB + BC = 3 + 3.5 cm  = 6.5 cm = AC.

However, in this case, the length of the third side is equal to the total lengths of the other two sides, which renders the triangle's condition incorrect.

Therefore, there does not exist any triangle with sides of 3 cm, 3.5 cm, and 6.5 cm.

Using substitution method, the solution of the system of equation 9x + y = 65, y = 3x - 19 is x = 7 and y = 2.

The system of equation can be solved using substitution method, elimination method and graphical method. Let's solve the system of equation using substitution method as follows:

9x + y = 65

y = 3x - 19

let's substitute the value of y in the equation(i)

9x + (3x - 19) = 65

9x + 3x - 19 = 65

12x - 19 = 65

add 19 to both sides of the equation

12x - 19 + 19 = 65 + 19

12x = 84

divide both sides by 12

x = 84 / 12

x = 7

Let's find y

y = 3(7) - 19

y = 21 - 19

y = 2

Therefore, the solution are x = 7 and y  =2.

Answer:

45%

Step-by-step explanation:

5% owns both so you remove that 5% from both the 40% and 10% because it's already in the "both" category. For example if Sara has both, then it also means that Sara is among the 5% that has both but also in the 40% that owns a bike and the 10% that owns a skateboard. You need to remove Sara from those two categories (skateboard and bike) because she's already in the "both" category.

So when you remove it, it's not 40 and 10 percent but 35 and 5 percent.

The answer is 35+5+5 = 45%

The value of x that makes the sentence 1/7 + x = 1/2 true is (d) 5/14

From the question, we have the following parameters that can be used in our computation:

A mathematical sentence

The mathematical sentence is given as

1/7 + x = 1/2

Next, we make x the subject of the formula

This is done by subtracting 1/7 from both sides of the equation

Using the above as a guide, we have the following:

1/7- 1/7 + x = 1/2 - 1/7

Evaluate the like terms on the left-hand side

So, we have the following representation

x = 1/2 - 1/7

Take the LCM of the fractions

x = (7 - 2)/14

Evaluate the difference on the right-hand side

So, we have the following representation

x = 5/14

Hence, the solution is (d) 5/14
