Answer:

umm i think it is B.

Step-by-step explanation:

The missing number of the series is 21.

The given sequence appears to follow the pattern of the Fibonacci sequence, where each number is the sum of the two preceding numbers. The Fibonacci sequence starts with 0 and 1, and each subsequent number is obtained by adding the two previous numbers.

Using this pattern, we can determine the missing number in the sequence.

0, 1, 1, 2, 3, 5, 8, 13, -, 34, 55

Looking at the pattern, we can see that the missing number is obtained by adding 8 and 13, which gives us 21.

If the paint gallon cost $12 and carton cost is $5 , then the amount saved per gallon buying the larger can is $8  .

We know that 1 gallon is = 4 quarts. So , a one-gallon can is equal to four one-quart cans.

To buy one gallon of paint, we need to buy 4 one-quart cans.

Each one-quart can costs $5, so 4 one-quart cans will cost:

⇒ 4 × $5 = $20 ,

Now, the cost of one gallon of paint if it is bought in one one-gallon can.

⇒ One one-gallon can costs $12.

Answer:

The positive angle less than 360° that is coterminal with -215° has a measure of 145°.

Step-by-step explanation:

From Geometry, we know that angles form a family of coterminal angles as function of number of revolutions done on original angle. We can represent the set of all coterminal angles by means of the following expression:

\(\theta_{c} = \theta_{o} + 360\cdot i\), \(i \in \mathbb{Z}\) (1)

Where:

\(\theta_{o}\) - Original angle, in sexagesimal degrees.

\(\theta_{c}\) - Coterminal angle, in sexagesimal degrees.

\(i\) - Coterminal angle index, no unit.

If we know that \(\theta_{o} = -215^{\circ}\) and \(i = 1\), then the coterminal angle that is less than 360° is:

\(\theta_{c} = -215^{\circ} + 360\cdot (1)\)

\(\theta_{c} = 145^{\circ}\)

The positive angle less than 360° that is coterminal with -215° has a measure of 145°.

The demand forecast for year 5 using the double exponential smoothing method is 134.

To calculate the demand forecast for year 5 using double exponential smoothing, we need to apply the following formula:

F_t+1 = F_t + (α * D_t) + (β * T_t)

Where:

F_t+1 is the forecast for the next period (year 5 in this case).

F_t is the forecast for the current period (year 2 in this case).

α is the smoothing factor for the level (given as 0.3).

D_t is the actual demand for the current period (year 2 in this case).

β is the smoothing factor for the trend (given as 0.2).

T_t is the trend forecast for the current period (year 2 in this case).

Given values:

F_t = 100 (demand forecast for year 2)

D_t = 100 (actual demand for year 2)

T_t = 10 (trend forecast for year 2)

α = 0.3 (smoothing factor for level)

β = 0.2 (smoothing factor for trend)

Let's calculate the demand forecast for year 5 step-by-step:

Calculate the level component for year 2:

L_t = F_t + (α * D_t) = 100 + (0.3 * 100) = 100 + 30 = 130

Calculate the trend component for year 2:

B_t = (β * (L_t - F_t)) / (1 - β) = (0.2 * (130 - 100)) / (1 - 0.2) = (0.2 * 30) / 0.8 = 6

Calculate the forecast for year 3:

F_t+1 = L_t + B_t = 130 + 6 = 136

Calculate the level component for year 3:

L_t+1 = F_t+1 + (α * D_t+1) = 136 + (0.3 * 150) = 136 + 45 = 181

Calculate the trend component for year 3:

B_t+1 = (β * (L_t+1 - F_t+1)) / (1 - β) = (0.2 * (181 - 136)) / (1 - 0.2) = (0.2 * 45) / 0.8 = 11.25

Calculate the forecast for year 4:

F_t+2 = L_t+1 + B_t+1 = 181 + 11.25 = 192.25

Calculate the level component for year 4:

L_t+2 = F_t+2 + (α * D_t+2) = 192.25 + (0.3 * 112) = 192.25 + 33.6 = 225.85

Calculate the trend component for year 4:

B_t+2 = (β * (L_t+2 - F_t+2)) / (1 - β) = (0.2 * (225.85 - 192.25)) / (1 - 0.2) = (0.2 * 33.6) / 0.8 = 8.4

Calculate the forecast for year 5:

F_t+3 = L_t+2 + B_t+2 = 225.85 + 8.4 = 234.25 ≈ 234 (rounded to the nearest whole number)

Therefore, the demand forecast for year 5 using double exponential smoothing is 234.

The value of n is 1650 after oil is transferred from Tank A and Tank B to Tank C.

It is given that initially,

Oil in tank A = n

Oil in tank B = n + 150

Oil in tank C = 0

Amount of oil transferred to tank C by tank A = 500 liters

Let us say 'x' amount of oil was transferred to tank C from tank B.

The amount of oil left in tank A after transferring 500 liters to tank C = n-500

Amount of oil left in tank B after transferring 'x' litres to tank C

= n + 150 - x

Amount of oil in tank C now = 500 + x

Since it is given that all three tanks contain the same amount of oil now. i.e. the new amount of oil in tank A = new amount of oil in tank B

n - 500 = n + 150 - x

x = 650

The new amount of oil in tank B = new amount of oil in tank C

n + 150 - x = 500 + x

n = 350 + 2x

Compound Interest Analysis With Applications

This site is a part of the JavaScript E-labs learning objects for decision making. Other JavaScript in this series are categorized under different areas of applications in the MENU section on this page.

Professor Hossein Arsham    

Compound Interest: The future value (FV) of an investment of present value (PV) dollars earning interest at an annual rate of r compounded m times per year for a period of t years is:

FV = PV(1 + r/m)mt

or

FV = PV(1 + i)n

where i = r/m is the interest per compounding period and n = mt is the number of compounding periods.

One may solve for the present value PV to obtain:

PV = FV/(1 + r/m)mt

Numerical Example: For 4-year investment of $20,000 earning 8.5% per year, with interest re-invested each month, the future value is

FV = PV(1 + r/m)mt   = 20,000(1 + 0.085/12)(12)(4)   = $28,065.30

Notice that the interest earned is $28,065.30 - $20,000 = $8,065.30 -- considerably more than the corresponding simple interest.

Effective Interest Rate: If money is invested at an annual rate r, compounded m times per year, the effective interest rate is:

reff = (1 + r/m)m - 1.

This is the interest rate that would give the same yield if compounded only once per year. In this context r is also called the nominal rate, and is often denoted as rnom.

Numerical Example: A CD paying 9.8% compounded monthly has a nominal rate of rnom = 0.098, and an effective rate of:

r eff =(1 + rnom /m)m   =   (1 + 0.098/12)12 - 1   =  0.1025.

Thus, we get an effective interest rate of 10.25%, since the compounding makes the CD paying 9.8% compounded monthly really pay 10.25% interest over the course of the year.

Mortgage Payments Components: Let where P = principal, r = interest rate per period, n = number of periods, k = number of payments, R = monthly payment, and D = debt balance after K payments, then

R = P × r / [1 - (1 + r)-n]

and

D = P × (1 + r)k - R × [(1 + r)k - 1)/r]

Step-by-step explanation:

Given that $OF = 9$ and $OF' = 12,$ where $F$ and $F'$ are the foci of the ellipse, we can determine the lengths of the major and minor axes.

In an ellipse, the sum of the distances from any point on the ellipse to the two foci is constant. This property is expressed by the equation:

$$PF + PF' = 2a,$$

where $P$ is any point on the ellipse and $a$ is the semi-major axis. In our case, $P = O,$ and since $OF = 9$ and $OF' = 12,$ we have:

$$9 + 12 = 2a,$$

$$21 = 2a.$$

Therefore, the semi-major axis $a$ is equal to $\frac{21}{2} = 10.5.$

The distance between the center of the ellipse and each focus is given by $c,$ where $c$ is related to $a$ and the semi-minor axis $b$ by the equation:

$$c = \sqrt{a^2 - b^2}.$$

We can solve for $b$ using the distance to one focus:

$$c = \sqrt{a^2 - b^2},$$

$$c^2 = a^2 - b^2,$$

$$b^2 = a^2 - c^2,$$

$$b = \sqrt{a^2 - c^2}.$$

Substituting the known values:

$$b = \sqrt{10.5^2 - 9^2},$$

$$b = \sqrt{110.25 - 81},$$

$$b = \sqrt{29.25},$$

$$b \approx 5.408.$$

Therefore, the semi-minor axis $b$ is approximately $5.408.$

Finally, we can determine the lengths of the major and minor axes:

The major axis $\overline{AB}$ is twice the semi-major axis, so $\overline{AB} = 2a = 2(10.5) = 21.$

The minor axis $\overline{CD}$ is twice the semi-minor axis, so $\overline{CD} = 2b = 2(5.408) \approx 10.816.$

Therefore, the major axis $\overline{AB}$ is $21$ units long, and the minor axis $\overline{CD}$ is approximately $10.816$ units long.

1. Tan θ = √11/5

2. Cosec θ = 6√11 /11

3. Cos θ = 5/6

Step-by-step explanation:

Let the side opposite to angle θ be y.

The value of y can be obtained by using the pythagoras theory as follow:

b² = 6² – 5²

b² = 36 – 25

b² = 11

Take the square root of both side.

b = √11

1. Determination of Tan θ

Tan θ =?

Opposite = √11

Adjacent = 5

Tan θ = Opposite /Adjacent

Tan θ = √11/5

2. Determination of Cosec θ.

We'll begin by calculating the Sine θ. This is illustrated below:

Sine θ =?

Opposite = √11

Hypothenus = 6

Sine θ = Opposite /Hypothenus

Sine θ = √11/6

Now, we shall determine Cosec θ as follow:

Cosec θ = 1/Sine θ

Sine θ = √11/6

Cosec θ = 1 ÷ √11/6

Cosec θ = 1 × 6/√11

Cosec θ = 6/√11

Rationalise the denominator

Cosec θ = 6/√11 × √11/√11

Cosec θ = 6√11 /11

3. Determination of Cos θ.

Cos θ =?

Adjacent = 5

Hypothenus = 6

Cos θ = Adjacent / Hypothenus

Cos θ = 5/6

Answer:

the Riemann Sum for $f(x)=2x^2$ with four equal subintervals using right-hand endpoints as the sample points is $\frac{15}{2}$.

Step-by-step explanation:

To evaluate the Riemann Sum for the function $f(x)=2x^2$ with four equal subintervals using right-hand endpoints as the sample points, we first need to determine the width of each subinterval. Since we have four subintervals to cover the interval $[0, 2]$, each subinterval has a width of $\Delta x = \frac{2-0}{4} = \frac{1}{2}$.

Next, we need to choose a sample point from each subinterval to evaluate the function. Since we are using right-hand endpoints as the sample points, we choose the endpoint of each subinterval as the sample point. The four subintervals are:

$[0, \frac{1}{2}]$, with sample point $x_1 = \frac{1}{2}$

$[\frac{1}{2}, 1]$, with sample point $x_2 = 1$

$[1, \frac{3}{2}]$, with sample point $x_3 = \frac{3}{2}$

$[\frac{3}{2}, 2]$, with sample point $x_4 = 2$

The Riemann Sum is then given by:

∑i=14f(xi)Δx=f(x1)Δx+f(x2)Δx+f(x3)Δx+f(x4)Δx=2(12)2⋅12+2(1)2⋅12+2(32)2⋅12+2(2)2⋅12=12+2+92+4=152i=1∑4​f(xi​)Δx​=f(x1​)Δx+f(x2​)Δx+f(x3​)Δx+f(x4​)Δx=2(21​)2⋅21​+2(1)2⋅21​+2(23​)2⋅21​+2(2)2⋅21​=21​+2+29​+4=215​​

Therefore, the Riemann Sum for $f(x)=2x^2$ with four equal subintervals using right-hand endpoints as the sample points is $\frac{15}{2}$.

The Riemann Sum is 15/2 or 7.5.

To evaluate the Riemann Sum for the function f(x) = 2x^2 on the interval [0, 2] using 4 equal subintervals and right-hand endpoints, follow these steps:

1. Determine the width of each subinterval:
  Δx = (b - a) / n = (2 - 0) / 4 = 0.5

2. Identify the right-hand endpoints of each subinterval:
  x1 = 0.5, x2 = 1, x3 = 1.5, x4 = 2

3. Evaluate the function at each right-hand endpoint:
  f(x1) = 2(0.5)^2 = 0.5
  f(x2) = 2(1)^2 = 2
  f(x3) = 2(1.5)^2 = 4.5
  f(x4) = 2(2)^2 = 8

4. Calculate the Riemann Sum using these values:
  Riemann Sum = Δx * (f(x1) + f(x2) + f(x3) + f(x4))
  Riemann Sum = 0.5 * (0.5 + 2 + 4.5 + 8)
  Riemann Sum = 0.5 * (15)
  Riemann Sum = 7.5

To calculate the area of the rectangle, we multiply its length by its width. Given that the length is measured to be 6.4 ± 0.2 cm and the width is measured to be 8.3 ± 0.2 cm, we can calculate the area as follows:

Length = 6.4 cm ± 0.2 cm

Width = 8.3 cm ± 0.2 cm

The maximum possible length is 6.6 cm (6.4 cm + 0.2 cm), and the minimum possible length is 6.2 cm (6.4 cm - 0.2 cm).

Similarly, the maximum possible width is 8.5 cm (8.3 cm + 0.2 cm), and the minimum possible width is 8.1 cm (8.3 cm - 0.2 cm).

Now, we can calculate the area of the rectangle using the maximum and minimum values:

Maximum area = Maximum length × Maximum width = 6.6 cm × 8.5 cm = 56.1 cm²

Minimum area = Minimum length × Minimum width = 6.2 cm × 8.1 cm = 50.22 cm²

Therefore, the area of the rectangle is within the range of 50.22 cm² to 56.1 cm².
