Answer:

  G'(y) = 4y^7(y+4)/(y+2)^5

Step-by-step explanation:

Work it a piece at a time.

Define z = y^2/(y+2). Then your derivative is found from the power rule as ...

  G = z^4

  G' = 4z^3·z'

Now, define z = u/v. Then your derivative is found using the quotient rule:

  z' = (vu' -uv')/v^2 = ((y+2)(2y) -(y^2)(1))/(y+2)^2

Putting this together we have ...

  [tex]G'(y)=4\left(\dfrac{y^2}{y+2}\right)^3\cdot\dfrac{y^2+4y}{(y+2)^2}\\\\\boxed{G'(y)=\dfrac{4y^8+16y^7}{(y+2)^5}}[/tex]

Answer:

a. Probability the reservoir will be empty after five days

e-1.5 + 0.6 e-1.5 e-1.5

b. Probability the reservoir will be empty sometime within the next ten days

Probability of rain falls in next ten days = 10 x 0.4

                                                                      =4

Step-by-step explanation:

The water level of the reservoir is depleted at a constant rate of 1000 units daily.

Rainfalls occur to the Poisson process with a rate of 0.3 per day.

a) Probability the reservoir will empty after five days is when there is no rain in the next five days.

Rainfall rate = 0.3 per day

Expected rain fall = 5 x 0.3 =1.5

Mean = µ =1.5, rain fall =x = 0

By using Poisson distribution formula, we get

P (empty) =p( empty at 5 day) + p (1.5 x 5000) x p(empty in 5 day)

                = e-1.5 + 0.6 e-1.5 e-1.5

b)

The next ten days reservoir will be empty if there will be no rain.

There will be one rain of 5000 units in the next ten days.

Probability of rain falls in next ten days = 10 x 0.4

                                                                      =4

Hence, four is the probability of rain falls in the next ten days

The angle between the ground and the steepest slope on the real rollercoaster is approximately 89.998°.

A model rollercoaster is built to a scale of 1:32. In the model rollercoaster, the angle between the ground and the steepest slope is 110°.What is the angle between the ground and the steepest slope on the real rollercoaster?

To determine the angle between the ground and the steepest slope on the real rollercoaster, you need to consider the scale of the model rollercoaster.To find the real rollercoaster angle, you should use a scale factor that relates the model rollercoaster to the real one.

The scale factor should multiply the model angle to obtain the real one. Since the scale factor relates the model length to the real length, it should relate the horizontal distance and the vertical height.

The horizontal and vertical lengths are in a ratio of 32:1 for the model. This means that for every 32 units in the model, there is one unit in the real rollercoaster. Therefore, we can say that the horizontal length of the real rollercoaster is 32 times the horizontal length of the model rollercoaster.

That is:h(real) = 32h(model)Similarly, the vertical height of the real rollercoaster is 32 times the vertical height of the model rollercoaster. That is:v(real) = 32v(model)

The tangent of an angle equals the vertical height divided by the horizontal distance. Therefore, the tangent of the real angle equals the tangent of the model angle times the scale factor.

That is:tanθ(real) = 32tanθ(model)By substitution,θ(real) = arctan(32tanθ(model))For the given model angle of 110°,

the corresponding real angle is:θ(real) = arctan(32tan110°)θ(real) = arctan(32(-2.74747741945462))θ(real) = arctan(-87.91927694142864)θ(real) ≈ -89.998°

The negative sign indicates that the angle is measured below the horizontal line.

Answer:

x = 8/3

Step-by-step explanation:

Step 1: Write equation

5 = 3x - 3

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

5 = 3(8/3) - 3

5 = 8 - 3

5 = 5

Answer:

x= [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

5=3x-3

first, add 3 to both sides:

5 +3 = 3x-3 +3

8=3x

then, divide both sides by 3:

8 ÷3 = 3x ÷3

and the answer can be written as x = [tex]\frac{8}{3}[/tex] or x = 2[tex]\frac{2}{3}[/tex]

Answer:

  AB ≈ 5.39

Step-by-step explanation:

If you draw a line down from A, and another line left from B, the lines will intersect to form a right triangle with AB as the hypotenuse. You can use the Pythagorean theorem to find the length AB.

The vertical leg is 2 grid squares (units) long. The horizontal leg is 5 grid squares (units) long.

Then the hypotenuse, AB, is ...

  AB = √(2² +5²) = √(4 +25) = √29

  AB ≈ 5.39

The length of AB is about 5.39 units.

Step-by-step explanation:

The cost of each for manufacturing necklace is $500.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

Let's say the cost of one necklace is x dollars.

Now,

Profit percentage = (selling price - cost) / cost × 100

20% = (600 - x) / x × 100

600 - x = 0.2x

0.2x + x = 600

1.2x = 600

x = 500

Hence "The cost of each manufacturing necklace is $500".

Step-by-step explanation:

Answer:

n = 298

318 - 6% = 298

The value of the number 'n' is 300.

Given the parameter:

"The number n is increased by 6% and the result is 318".

To determine the value of n, simply multiply the percent increase, and n equate to 318 to form an equation.

Since, its a percent increase; we add 6% to 100%

6% + 100% = 0.06 + 1 = 1.06

Hence:

1.06 × n = 318

Solve for n:

Divide both sides by 1.06:

n = 318/1.06

n = 300

Therefore, n has a value of 300.
