The company's profits on June 1, 2002 is $4500 and the company's profits many years into the future is $1000 per month.

The equation f(t) = (t^2 + 9) / (t^2+2) provides the monthly profits, in thousands of dollar, where t refers to months after June 1, 2002.

The company’s profit on June 1, 2002 using the equation is when t = 0 months

f(0) = (0^2 + 9) / (0^2+2) = 9/2 = 4.5 or $4500.

The company’s profit on many years into the future using the equation is given by:

Limit(t→∞)((t^2+9)/(t^2+2))= Limit(t→∞)(2t/2t)=1

Hence the monthly profit is $1,000.

Answer:

  (i)  x = 17 cm

  (ii) 360 cm²

  (iii) 14400 cm³

  (iv) 4000 cm²

Step-by-step explanation:

You want the slant side length, end area, volume, and total surface area of an isosceles trapezoidal prism with end bases 16 cm and 32 cm and end height 15 cm. The length of the prism is 40 cm.

The slant side of the base is the hypotenuse of a right triangle that has legs of 15 cm and (32 -16)/2 = 8 cm. You recognize these numbers as belonging to the {8, 15, 17} Pythagorean triple, so you know the slant side is 17 cm.

If you don't recognize that triple, you can figure the side length as ...

  x = √(15² +8²) = √(225 +64) = √289

  x = 17 . . . centimeters

The area of the end trapezoid is given by ...

  A = 1/2(b1 +b2)h = 1/2(32 +16)(15) = 360 . . . cm²

The area of the end surface is 360 cm².

The volume of the prism is given by ...

  V = Bh

where B is the area of the base, and h is the length between bases.

  V = (360 cm²)(40 cm) = 14400 cm³

The volume of the prism is 14400 cubic centimeters.

The total surface area is the sum of the areas of the two bases and the lateral area. The lateral area is the product of the perimeter of the base and the length of the prism.

  total area = 2 · base area + lateral area

  total area = 2 · 360 cm² + (32 + 17 + 16 + 17 cm)(40 cm)

  total area = 720 cm² + 3280 cm² = 4000 cm²

The total surface area of the prism is 4000 square centimeters.

The time taken by Bert to travel 50 miles distance with constant speed 30 miles per hour is an hour 40 minutes. So, right answer is option (b).

Speed is defined as the rate at which a particular object able to move or operate. It is a ratio of amount of distance to the time. Speed of object may be fast , slow or constant. The constant speed means there is no increase or decrease in speed during rides.

We have,bert's constant speed=30 miles/hour .

We have to calculate the time taken by Bert to travel 50 miles, i.e distance = 50 miles . Let "t hours " be time taken by Bert to travel 50 miles.

Speed= distance/time

=> time = distance/speed

=> t = 50 miles /30 miles/1 hour

=> t = 5/3 hours

Conversion of hours into minutes :

one hour = 60 minutes

5/3 hour =( 5/3 )× 60 minutes

=> 5/3 hour = 100 minutes = 60 minutes + 40 minutes= 1 hour 40 minutes

So, required time is 1 hour 40 minutes.

The width of the box m = 5 units

The width of  the box = m units

Where m is a prime number

Height of the box = m+2 units

The length of the box = m -1 units

The volume of the box = 140 cubic units

The volume of the box = Length × width × height

140 = m × (m+2) × (m-1)

140 = (m^2 + 2m )(m-1)

140 = m^3 - m^2 + 2m^2 - 2m

140 = m^3 + m^2 - 2m

m^3 + m^2 - 2m - 140 = 0

We can split the equation by taking the common term outside

(m-5) (m^2 + 6m + 28) = 0

Therefore, one value of m = 5

For the given data for the reaction, 2 A + 2 B + 4 C => D + E + 3 F, the reaction is zero order in A, second order in B, first order in C and third order overall.

Let the order of reactions be a, b and c for reactions A, B and C respectively.

Then A^{a}B^{b}C^{c} ∝ R

Considering experiment 1 and 2, only concentration of A changes but it has no effect in the total. So a = 0.

Considering experiment 2 and 3, concentration of A and B changes, but it is found that A has no effect. So

(B₃ / B₂)^{b} = (R₃ / R₂)

(0.4/ 0.2)^{b} = (0.008/ 0.002)

2^{b} = 4

Therefore b = 2

Considering experiment 2 and 4

(A₄/ A₂)^{a}(B₄/B₂)^{b}(C₄/ C₂)^{c}= (R₄/ R₂)

(0.4/ 0.2)^{0}(0.6/ 0.2)^{2}(0.2/ 0.4)^{c}= (0.009/ 0.002)

The area of the region enclosed by one loop of the curve r = sin(10θ) is π/40.

We have to find the area of the region enclosed by one loop of the curve.

The given curve is:

r = sin(10θ)

Consider the region r = sin(10θ)

The area of region bounded by the curve r = f(θ) in the sector a ≤ θ ≤ b is

A = [tex]\int^{b}_{a}\frac{1}{2}r^2d\theta[/tex]

Now to find the area of the region enclosed by one loop of the curve, we have to find the limit by setting r=0.

sin(10θ) = 0

sin(10θ) = sin0   or    sin(10θ) = sinπ

So θ = 0             or      θ = π/10

Hence, the limit of θ is 0 ≤ θ ≤ π/10.

Now the area of the required region is

A = [tex]\int^{\pi/10}_{0}\frac{1}{2}(\sin10\theta)^2d\theta[/tex]

A = [tex]\frac{1}{2}\int^{\pi/10}_{0}\sin^{2}10\theta d\theta[/tex]

A = [tex]\frac{1}{2}\int^{\pi/10}_{0}\frac{(1-\cos20\theta)}{2}d\theta[/tex]

A = [tex]\frac{1}{4}\int^{\pi/10}_{0}(1-\cos20\theta)d\theta[/tex]

A = [tex]\frac{1}{4}\left[(\theta-\frac{1}{20}\sin20\theta)\right]^{\pi/10}_{0}[/tex]

A = [tex]\frac{1}{4}\left[(\frac{\pi}{10}-\frac{1}{20}\sin20\frac{\pi}{10})-(0-\frac{1}{20}\sin20\cdot0)\right][/tex]

A = [tex]\frac{1}{4}\left[(\frac{\pi}{10}-\frac{1}{20}\sin2\pi)-(0-\sin0)\right][/tex]

A = 1/4[(π/10-0)-(0-0)]

A = 1/4(π/10)

A = π/40

The critical points for the inequality (2x+5/x+2>_ x-1/x-2), are x = -2 and x = 2. Option A

Generally, To find the critical points for the inequality, you need to set the expression on the left side of the inequality equal to zero and solve for x. This will give you the values of x where the inequality changes direction.

In this case, the inequality is:

2x + 5/(x + 2) > 0

To find the critical points, you can set the expression on the left side equal to zero and solve for x:

0 = 2x + 5/(x + 2)

0 = 2x + 5 - 5/(x + 2)

0 = 2x - 5 + 5/(x + 2)

0 = 2x - 5 + 5(x + 2)/(x + 2)

0 = 2x - 5 + 5x + 10

0 = 7x - 15

x = -2, x = 2

Therefore, the critical points for the inequality are x = -2 and x = 2.

It is not correct to say that the critical points are x = -6 and x = 2, x = -4 and x = 2, or x = 2. These values do not correspond to any points where the inequality changes direction.

The proportion of stocks invested in the optimal risky portfolio can be calculated with the use of following formula:

Portfolio Invested in the Stock = [(Expected Return of the Stock - Risk Free Rate)*(Standard Deviation of Bond)^2 - (Expected Return of the Bond - Risk Free Rate)*Covariance between Bond and Stock]/[(Expected Return of the Stock - Risk Free Rate)*(Standard Deviation of Bond)^2 + (Expected Return of the Bond - Risk Free Rate)*(Standard Deviation of Stock)^2 - (Expected Return of Stock - Risk Free Rate + Expected Return of Bond - Risk Free Rate)]*Covariance between Bond and Stock

Portfolio Invested in Bond = 1 - Portfolio Invested in the Stock

Here, Risk Free Rate = 4 and Covariance = 32*24*.1250 = 96

Using these values and other information provided in the question, we get,

Portfolio Invested in the Stock = [(10 - 4)*(24)^2 - (7 - 4)*96]/(10 - 4)*(24)^2 + (7 - 4)*(32)^2 - [(10 - 4 + 7 - 4)]*96 = .5593

Portfolio Invested in Bond = 1-.5593 = .4407

Step 2: Calculate Expected Return and Standard Deviation of the Optimal Risky Portfolio

Expected Return = Portfolio Invested in Stock*Expected Return of Stock Portfolio Invested in Bond*Expected Return of Bond = .5593*10% + .4407*7% = 8.68%

Standard Deviation = [(Portfolio Invested in Stock)^2*(Standard Deviation of Stock)^2 + (Portfolio Invested in Bond)^2*(Standard Deviation of Bond)^2 + 2*(Portfolio Invested in Stock)*(Portfolio Invested in Bond)]^(1/2) = [(.5593)^2*(32)^2 + (.4407)^2*(24)^2 + 2*(.5593)*(.4407)*(96)]^(1/2) = 21.90%

Step 3: Calculate Reward-to-Volatility Ratio

The reward-to-volatility ratio can be calculated with the use of following formula:

A square's area an is growing at a rate of 6 cm2 each minute. The side length of the square is increasing at a rate of 2.45 cm/min.

The side length of a square is related to the area of the square by the equation side length = square root of (area). That means, if the area is increasing, the side length of the square is also increasing. To calculate the rate at which the side length is changing, we can take the derivative of the equation side length = square root of (area) with respect to time. This gives us a rate of change of 2.45 cm/min. This means that for every minute the area increases by 6 cm2, the side length of the square will increase by 2.45 cm.

Rate of change = d(side length) / dt

= (1/2) * (d(area) / dt) / (square root of (area))

= (1/2) * (6 cm2/min) / (square root of (area))

To determine the distance from the ship's point of departure, we must first break down the distance traveled into x and y components. Initially, the ship traveled 35 miles due east, which can be represented as 35 miles on the x-axis. When the ship adjusted its course 40 degrees northward, it traveled 45 miles in that direction. This can be represented as 45 miles in the y direction, forming a triangle with the origin (point of departure). Using the Pythagorean theorem, we can calculate the hypotenuse of the triangle, which is equal to the distance from the point of departure. The hypotenuse of the triangle is equal to the square root of (35^2 + 45^2), which is equal to approximately 59.9 miles. Therefore, the distance from the ship's point of departure is approximately 59.9 miles.
