The boundary lines are y > -3x + 4: dotted line and  y <= 8x + 1: solid line

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

y > -3x + 4

y <= 8x + 1

The boundary line for the inequality "<" is a dotted line, which means that the endpoint is not included in the solution set.

The boundary line for the inequality ">=" is a solid line, which means that the endpoint is included in the solution set.

Answer:

Step-by-step explanation:

rate of change is essentially slope

\(Rate Of Change = \frac{rise}{run}\)              or

\(Rate Of Change = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }\)          or

\(Rate Of Change = \frac{f(x_{2})- f(x_{1}) }{x_{2} -x_{1} }\)

Mean of rt = 0.02,

Variance of rt = 0.02,

Lag-1 Autocorrelation (ρ1) = -0.01,

Lag-2 Autocorrelation (ρ2) = Unknown,

1-step ahead forecast = -0.005,

2-step ahead forecast = 0.02,

The standard deviation of forecast errors = √0.02.

We have,

To find the mean and variance of the return series, we can substitute the given model into the equation and calculate:

Mean of rt:

E(rt) = E(0.02 + 0.5rt-2 + et)

= 0.02 + 0.5E(rt-2) + E(et)

= 0.02 + 0.5 * 0 + 0

= 0.02

The variance of rt:

Var(rt) = Var(0.02 + 0.5rt-2 + et)

= Var(et) (since the term 0.5rt-2 does not contribute to the variance)

= 0.02

The mean of the return series rt is 0.02, and the variance is 0.02.

To compute the lag-1 and lag-2 autocorrelations of rt, we need to determine the correlation between rt and rt-1, and between rt and rt-2:

Lag-1 Autocorrelation:

ρ(1) = Cov(rt, rt-1) / (σ(rt) * σ(rt-1))

Lag-2 Autocorrelation:

ρ(2) = Cov(rt, rt-2) / (σ(rt) * σ(rt-2))

Since we are given r100 = -0.01 and r99 = 0.02, we can substitute these values into the equations:

Lag-1 Autocorrelation:

ρ(1) = Cov(rt, rt-1) / (σ(rt) * σ(rt-1))

= Cov(r100, r99) / (σ(r100) * σ(r99))

= Cov(-0.01, 0.02) / (σ(r100) * σ(r99))

Lag-2 Autocorrelation:

ρ(2) = Cov(rt, rt-2) / (σ(rt) * σ(rt-2))

= Cov(r100, r98) / (σ(r100) * σ(r98))

To compute the 1- and 2-step-ahead forecasts of the return series at

t = 100, we use the given model:

1-step ahead forecast:

E(rt+1 | r100, r99) = E(0.02 + 0.5rt-1 + et+1 | r100, r99)

= 0.02 + 0.5r100

2-step ahead forecast:

E(rt+2 | r100, r99) = E(0.02 + 0.5rt | r100, r99)

= 0.02 + 0.5E(rt | r100, r99)

= 0.02 + 0.5(0.02 + 0.5r100)

The associated standard deviation of the forecast errors can be calculated as the square root of the variance of the return series, which is given as 0.02.

Thus,

Mean of rt = 0.02,

Variance of rt = 0.02,

Lag-1 Autocorrelation (ρ1) = -0.01,

Lag-2 Autocorrelation (ρ2) = Unknown,

1-step ahead forecast = -0.005,

2-step ahead forecast = 0.02,

The standard deviation of forecast errors = √0.02.

----------------------------------

Solve the given equation in below steps:

The values are:

cosec² B ≈ 5.2

tan(A - B) ≈ 0.5

We have,

To calculate the values, we'll use the following trigonometric identities:

- Cosecant squared (cosec²) is the reciprocal of the sine squared (sin²): cosec² B = 1/sin² B

- Tangent (tan) difference formula: tan(A - B) = (tan A - tan B) / (1 + tan A * tan B)

Given:

A = 40°

B = 25°

To find cosec² B:

Find sin B using the sine function: sin B = sin(25°)

Calculate cosec² B using the reciprocal of the sine squared: cosec² B = 1/sin² B

To find tan(A - B):

Find tan A using the tangent function: tan A = tan(40°)

Find tan B using the tangent function: tan B = tan(25°)

Calculate tan(A - B) using the tangent difference formula: tan(A - B) = (tan A - tan B) / (1 + tan A * tan B)

Let's calculate the values now:

cosec² B:

sin B = sin(25°) = 0.4226 (rounded to four decimal places)

cosec² B = 1/sin² B = 1/0.4226² ≈ 5.2268 (rounded to one decimal place)

tan(A - B):

tan A = tan(40°) = 0.8391 (rounded to four decimal places)

tan B = tan(25°) = 0.4663 (rounded to four decimal places)

tan(A - B) = (tan A - tan B) / (1 + tan A x tan B)

= (0.8391 - 0.4663) / (1 + 0.8391 * 0.4663)

= 0.4662 (rounded to one decimal place)

Therefore,

The values are:

cosec² B ≈ 5.2

tan(A - B) ≈ 0.5

The future value of the deposits at the end of 5 years is approximately $6,138.74.

To calculate the future value of the deposits, we can use the formula for compound interest:

FV = P(1 + r/n)^(nt)

Where: FV is the future value

P is the principal amount (initial deposit)

r is the annual interest rate (3% in this case)

n is the number of times interest is compounded per year (quarterly in this case)

t is the number of years

In this case, the principal amount is $1,000, the annual interest rate is 3% (or 0.03), the number of times interest is compounded per year is 4 (quarterly), and the number of years is 5.

Plugging in these values into the formula, we get: FV = $1,000(1 + 0.03/4)^(4*5)

Calculating this, the future value of the deposits at the end of 5 years is approximately $6,138.74.

Answer: -4096

Step-by-step explanation: Use the geometric sequence formula to find the 10th term (image attached). So, the 10th term = 8(-2)^9

Note: the common ratio can be found by 2ndterm/1stterm

Answer:

a₁₀ = -4096

Step-by-step explanation:

Geometric sequence

General form of a geometric sequence:

\(\boxed{a_n=ar^{n-1}}\)

where:

Given terms of the geometric sequence:

To find the common ratio (r), divide consecutive terms:

\(\implies \dfrac{a_3}{a_2}=\dfrac{32}{-16}=-2\)

Substitute the values of a and r into the formula to create an equation for the nth term of the sequence:

\(\implies a_n=8(-2)^{n-1}\)

To find the 10th term of the sequence, substitute n = 10 into the equation:

\(\begin{aligned}\implies a_{10}&=8(-2)^{10-1}\\&=8(-2)^{9}\\&=8(-512)\\&=-4096\end{aligned}\)

Therefore, the 10th term of the given geometric sequence is -4096.

Answer:

x=5+5√2; x=5-5√2

Step-by-step explanation:

To complete the square we need to turn part of the equation into a perfect square trinomial. Remember, in any equation we can do anything we like to the numbers as long as both sides stay equal.

First, let's subtract 10 from both sides.

x^2-10x=25

This does not factor, so we need to turn it into a perfect square trinomial by adding the quantity equal to (b/2)^2. In this case, (b/2)^2 is 25.

x^2−10x+25=25+25

IMPORTANT: You must keep the sides of the equation equal, so we added a 25 to the right side as well to keep the equation true.

From here we can factor, simplify and find our zeroes.

(x-5)(x-5)=50

(x-5)^2=50

x-5=±√50

x=5±√50

√50=5√2

So our final answer is:

x=5+5√2; x=5-5√2
