Answer:

Flashlight.

Step-by-step explanation:

Which FlashLight are you looking for? Here are some Names and Explanations for them.

As a very general estimate, a low-lumen flashlight (under 50 lumens) will run for about 20-50 hours. A flashlight with 50-150 lumens will run for about 6-12 hours on it's highest setting, and high lumen flashlight or headlamp (over 150 lumens) will run about 2-8 hours on their highest settings.

Answer:

  A.  12.1 cm³

Step-by-step explanation:

Before the model soldier was added to the graduated cylinder, the volume in it was 50 mL. After the model soldier was immersed in the graduated cylinder, its volume was added to what was already there. That new total volume was 62.1 mL. The amount of volume the model soldier added was ...

  61.2 mL -50 mL = 12.1 mL = 12.1 cm³

_____

Additional comment

The volumes given in the problem statement are in milliliters (mL). The volumes given in the answer choices are cubic centimeters (cm³). These are two different names for the same volume.

__

The density of the soldier is (mass)/(volume) = (137.2 g)/(12.1 cm³) ≈ 11.34 g/cm³. This is equivalent to the density of lead.

The domain and range of the graph above in interval notation include the following:

Domain = [-6, 3]

Range = [-3, 3]

In Mathematics and Geometry, a domain refers to the set of all real numbers (x-values) for which a particular function (equation) is defined.

In Mathematics and Geometry, the horizontal portion of any graph is used to represent all domain values and they are both read and written from smaller to larger numerical values, which simply means from the left of any graph to the right.

By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following domain and range:

Domain = [-6, 3] or -6 ≤ x < 3.

Range = [-3, 3] or -3 < y < 3

The equivalent value of trigonometric relation sin⁻¹ ( √3/2 ) = π/3

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the trigonometric relation be represented as A

Now , the value of A is

sin⁻¹ ( √3/2 ) = θ

Now , the value of θ is calculated by

In a triangle , sin θ = opposite / hypotenuse

So , sin θ = √3/2

The value of θ = 60°

So , the measure of 60° in radians is θ = π/3

Hence , the value of θ from the trigonometric relation is π/3

Given :

There are 23 red shirts and 16 white shirts they will be put onto shelves in piles of 8.

To Find :

How many shirts will not fit evenly into 8 piles.

Solution :

We need to find the number of shirts which will not fit evenly into 8 piles.

What we need is the remainder of 23 divided by 8.

23 = 8×2 + 7

So, their are 7 shirts which will not fit evenly.

Hence, this is the required solution.

Under the units-of-activity method, the depreciation expense per mile for Bus #3 is $0.4616.

The units-of-activity method is one of the depreciation methods in use.

Under the units-of-activity method, the depreciation expense per unit is determined by dividing the depreciable amount by the total units of activity.

The depreciation amount (the value of the asset subject to depreciation) is the net of the total cost less the salvage value.

Depreciable amount of Bus #3 = $57,700 ($66,500 - $8,800)

Expected total miles for Bus #3 = 125,000

Depreciation expense per mile for Bus #3 = $0.4616 ($57,700 ÷ 125,000)

Using the Least Cost Method, 200 cases should be shipped to Toronto from Hamilton and 100 cases from Hamilton to London with the remaining 140 cases shipped from Waterloo to London to complete the orders.

The Least Cost Method is a method of solving transportation problems. The allocation starts by allocating with the cell or column with the minimum cost.

The lower-cost cells are first chosen over the higher-cost cells to obtain the least cost of transportation.

                        Toronto        London

Demand           200 cases   240 cases

Hamilton = 300 cases

Waterloo = 200 cases

                        Toronto        London

Hamilton           $0.50           $0.60

Waterloo           $0.70           $0.65

                        Toronto                              London

Hamilton           $100 (200 x $0.50)        $144 (240 x $0.60)

Waterloo           $140 (200 x $0.70)        $156 (240 x $0.65)

The number of cases that should be shipped from each warehouse to minimize transportation costs is as follows:

                        Toronto             London

Hamilton         200 cases         100 cases (at a total cost of $60)

Waterloo         0 case               140 cases (at a total cost of $91)

Total               200 cases        240 cases

Total transportation

costs       $100 (200 x $0.50)  $151 (100 x $0.60 + 140 x $0.65)

Thus, using the Least Cost Method, 200 cases should be shipped to Toronto from Hamilton and 100 cases from Hamilton to London with the remaining 140 cases shipped from Waterloo to London to complete the orders with the total transportation cost incurred for the two orders from Toronto and London as $251.

The value of the expression \(\sqrt[4]{a}^3\) when evaluated is \(a^\frac34\)

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

\(\sqrt[4]{a}^3\)

Consider an expression expressed as xⁿ

The expression can be expanded as

xⁿ = x * x * x .... in n places

Using the above as a guide, we have the following:

\(\sqrt[4]{a}^3 = \sqrt[4]{a} * \sqrt[4]{a} * \sqrt[4]{a}\)

Apply the exponent rule of indices

\(\sqrt[4]{a}^3 = a^\frac14 * a^\frac14 * a^\frac14\)

Apply the power rule of indices

\(\sqrt[4]{a}^3 = a^\frac34\)

Hence, the expression \(\sqrt[4]{a}^3\) when evaluated is \(a^\frac34\)

Step-by-step explanation:

Solution:

We can simplify the ratio 305 : 60 by dividing both terms by the greatest common factor (GCF).

The GCF of 305 and 60 is 5.

Divide both terms by 5.

305 ÷ 5 = 61

60 ÷ 5 = 12

Therefore:

305 : 60 = 61 : 12

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

We have,

To solve the integral ∫ (log(1 + x²) / (x + 1)²) dx, we can use the method of substitution.

Let's substitute u = x + 1, which implies du = dx. Making this substitution, the integral becomes:

∫ (log(1 + (u-1)²) / u²) du.

Expanding the numerator, we have:

∫ (log(1 + u² - 2u + 1) / u²) du

= ∫ (log(u² - 2u + 2) / u²) du.

Now, let's split the logarithm using the properties of logarithms:

∫ (log(u² - 2u + 2) - log(u²)) / u² du

= ∫ (log(u² - 2u + 2) / u²) du - ∫ (log(u²) / u²) du.

We can simplify the second integral:

∫ (log(u²) / u²) du = ∫ (2 log(u) / u²) du.

Using the power rule for integration, we can integrate both terms:

∫ (log(u² - 2u + 2) / u²) du = log(u² - 2u + 2) / u - 2 ∫ (log(u) / u³) du.

Now, let's focus on the second integral:

∫ (log(u) / u³) du.

This integral does not have a simple closed-form solution in terms of elementary functions.

It can be expressed in terms of a special function called the logarithmic integral, denoted as Li(x).

Therefore,

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.
