Answer:

x

Step-by-step explanation:

The composition of a function and its inverse is x.

Answer:

The slope of this line is 7/4 or 1.74 in decimal form.

m = 7/4 OR m = 1.75

Step-by-step explanation:

slope = y^2 - y^1 / x^2 - x^1

Let's pick any two points from the graph: (-1, -3) and (3, 4)

m = y^2 - y^1 / x^2 - x^1

m = 4 - (-3) / 3 - (-1)

m = 4 + 3 / 3 + 1

m = 7/4

m = 1.75

Answer:

m = 1.75 OR m = 7/5 in fraction form

Step-by-step explanation:

take any two points from the graph and plug them into the formula of slope.

slope = y2 - y1 / x2 - x1

Part 1: The percentage change in velocity was positive in Quarter 1 (Q1) 2020 and Quarter 3 (Q3) 2020. The percentage change in velocity was negative in Quarter 2 (Q2) 2020.

Part 2: Percentage change in velocity = -0.297

Part 3: C. People and banks were holding on to their money longer explain such a large change in velocity that occurred during the second quarter.

Part 2: During Q2, the percentage change in velocity can be calculated by using the following formula:

Velocity = (Nominal GDP / Real GDP) / (Money Supply / Nominal GDP)

Percentage change in velocity = (Velocity of 2020 - Velocity of 2019) / Velocity of 2019

Velocity of 2019 = (Nominal GDP of 2019 / Real GDP of 2019) / (Money Supply of 2019 / Nominal GDP of 2019) = Velocity of 2019 = (21,427.7 / 19,485.4) / (3,405.5 / 21,427.7)

Velocity of 2019 = 1.1290

Velocity of 2020 = (Nominal GDP of 2020 / Real GDP of 2020) / (Money Supply of 2020 / Nominal GDP of 2020)

Velocity of 2020 = (19,414.6 / 18,016.2) / (4,163.2 / 19,414.6)

Velocity of 2020 = 0.7940

Percentage change in velocity = (0.7940 - 1.1290) / 1.1290 = -0.297

Part 3: A substantial increase in the money supply can explain such a large change in velocity that occurred during Q2. When the money supply increased, people and banks had more money to spend and lend. However, the velocity decreased in Q2 despite a large increase in the money supply. This suggests that people and banks were holding on to their money longer and spending less during Q2. Therefore, option C is the correct answer.

The vector a with the same direction as (-10, 3, 10) and a length of 5 is approximately (-7.65, 2.29, 7.65).

To find a vector with the same direction as (-10, 3, 10) but with a length of 5, we can scale the original vector by dividing each component by its magnitude and then multiplying it by the desired length.

The original vector (-10, 3, 10) has a magnitude of √((-10)^2 + 3^2 + 10^2) = √(100 + 9 + 100) = √209.

To obtain a vector with a length of 5, we divide each component of the original vector by its magnitude:

x-component: -10 / √209

y-component: 3 / √209

z-component: 10 / √209

Now, we need to scale these components to have a length of 5. We multiply each component by 5:

x-component: (-10 / √209) * 5

y-component: (3 / √209) * 5

z-component: (10 / √209) * 5

Evaluating these expressions gives us the vector a:

a ≈ (-7.65, 2.29, 7.65)

Answer:

81.5

Step-by-step explanation:

<G and <H are congruent

<F and <I are congruent

so the last two angles in both triangles must also be congruent

this means that <K and <J are congruent

so we can create this equation: <K = <J

substitute the angles with what we know: 4\(y^{2}\) = 6\(y^{2}\) - 40

add 40 to both sides and subtract 4\(y^{2}\) from both sides: 40 = 2\(y^{2}\)

you get: 20 = \(y^{2}\)

root square on both sides: \(\sqrt{20}\) = \(\sqrt{y^{2} }\)

you get: y ≈ 4.5

substitute this into one of the equations for a missing variable:

6\(y^{2}\) -----> 6 (4.5 x 4.5) - 40

6 ( 20.25) - 40

121.5 - 40

81.5

Answer:

5x - 15 + 2x + 90 = 180

180 since it's a flat line, and all the angles should add up to 180 which is angle AOB, 90 degrees is already given in the middle.

Simplify all the terms (The algebra portion)

7x - 15 + 90 = 180

7x + 90 = 195

7x = 105

x = 105/7

x = 15

now substitute in x for all these angles

2(15) = 30 degrees is the angle GOB

5(15) - 15 = 60 degrees is the angle AOF

60 + 90 + 30 = 180 degrees.

and x = 15

7.1 cm  long is the arc intersected by a central angle .

a. The price of the consol is approximately $133.33.

b. The new price of the consol would be $100. The price of the consol falls by 24.99% and the interest rate rises by 1%.

c. Your holding period return is approximately -49.99%.

a. The price of the consol can be calculated using the formula for the present value of a perpetuity:

Price = Annual Payment / Interest Rate

In this case, the annual payment is $4 and the interest rate is 3%. Substituting these values into the formula:

Price = $4 / 0.03 ≈ $133.33

Therefore, the price of the consol is approximately $133.33.

b. To calculate the new price of the consol if the interest rate rises to 4%, we use the same formula:

New Price = Annual Payment / New Interest Rate

Substituting the values, we get:

New Price = $4 / 0.04 = $100

The percentage change in the price of the consol can be calculated using the formula:

Percentage Change = (New Price - Old Price) / Old Price * 100

Substituting the values, we have:

Percentage Change in Price = ($100 - $133.33) / $133.33 * 100 ≈ -24.99%

The percentage change in the interest rate is simply the difference between the old and new interest rates:

Percentage Change in Interest Rate = (4% - 3%) = 1%

Comparing the two percentages, we can see that the price of the consol falls by approximately 24.99%, while the interest rate rises by 1%.

c. The holding period return can be calculated using the formula:

Holding Period Return = (Ending Value - Initial Value) / Initial Value * 100

The initial value is the purchase price of the consol, which is $133.33, and the ending value is the price of the consol after one year with an interest rate of 6%. Using the formula for the present value of a perpetuity, we can calculate the ending value:

Ending Value = Annual Payment / Interest Rate = $4 / 0.06 = $66.67

Substituting the values into the holding period return formula:

Holding Period Return = ($66.67 - $133.33) / $133.33 * 100 ≈ -49.99%

Therefore, the holding period return is approximately -49.99%.

(a) The probability a randomly selected cocaine addict receives lithium is 1/3 or approximately 0.33. (b) The probability a randomly selected cocaine addict relapses is 20/72 or approximately 0.28. (c) The probability a randomly selected cocaine addict relapses or receives lithium is (18 + 20)/72 or approximately 0.53.

(d) The probability a randomly selected cocaine addict relapses and receives lithium is 18/72 or approximately 0.25. (e) The probability a randomly selected cocaine addict who relapsed received desipramine is 10/20 or 0.5.

In the given experiment, 72 chronic cocaine users were randomly assigned to three groups: desipramine, lithium, or placebo. After three years, the results showed that 10 out of 20 patients who received desipramine relapsed, 18 out of 72 patients who received lithium relapsed, and 20 out of 72 patients who received a placebo relapsed.

To calculate the probabilities, we divide the number of relevant outcomes by the total number of outcomes. Therefore, the probability a randomly selected cocaine addict receives lithium is 1/3 since one-third of the subjects were assigned to take lithium. The probability a randomly selected cocaine addict relapses is 20/72 because 20 out of 72 patients experienced a relapse. The probability a randomly selected cocaine addict relapses or receives lithium is (18 + 20)/72 since there were 18 relapses in the lithium group and 20 relapses in the placebo group. The probability a randomly selected cocaine addict relapses and receives lithium is 18/72, considering only the patients who received lithium. Lastly, the probability a randomly selected cocaine addict who relapsed received desipramine is 10/20 because 10 out of 20 patients who relapsed were in the desipramine group.
