How Would You Write The Following Expression As A Sum Or Difference?

Answers

Answer 1

Answer:

B: 1/3 log (2-x) - log 3x

Step-by-step explanation:

some log laws:

1) log xy = log x + log y

2) log (x/y) = log x - log y

3) log x^k = k log x

log ((∛2-x) / 3x)

= log ∛2-x  -  log 3x  (just like the 2nd law above)

log ∛2-x = log (2-x)^(1/3)  =  (1/3) log (2-x)   (just like the 3rd law above).

so we now have (1/3) log (2 - x)  - log 3x

This is option B in the question.

Answers

Burger Quick is able to estimate their wait time more consistently than Fast Chicken because it has a smaller IQR.

Burger Quick is able to estimate their wait time more consistently than Fast Chicken because it has a smaller IQR (interquartile range).

The IQR represents the range of the middle 50% of the data, and a smaller IQR indicates that the data is more tightly clustered around the median.

In this case, the IQR for Burger Quick is 15.5 - 9.5 = 6, while the IQR for Fast Chicken is 14.5 - 10 = 4.5.

This means that the wait times reported by Burger Quick are more consistent and predictable than those reported by Fast Chicken.

The range, on the other hand, represents the difference between the largest and smallest data points and does not provide information about the consistency of the data. Therefore, we cannot use the range to determine which drive-thru estimates their wait time more consistently.

Two observation towers A and B are located 10 miles apart scientist at tower A spot an exotic bird at 42° and scientist at tower B spot the same bird at 64° how far away from tower A is the exotic bird

Answers

The distance of bird away from the tower is  4.04 miles.

Given that,

Distance between A and B = 10 miles

To solve this problem,

Use the law of tangents and basic trigonometry.

Let  the distance from tower A to the bird = x

Then,

tan(180° - 64°) = x / (10 - d)

(where d is the distance from tower B to the bird)

tan(42°) = x / d

We can rearrange the first equation to get,

10 - d = x / tan(116°)

Substituting this into the second equation, we get:

⇒ tan(42°) = x / (x / tan(116°))

⇒ tan(42°) = tan(116°) x / x

⇒  x = 10 tan(42°) / (tan(116°) - tan(42°))

Plugging this into a calculator, we get:

x ≈ 4.04 miles

Therefore,

The exotic bird is approximately 4.04 miles away from tower A.

If you pour a cup of coffee that is 200F, and set it on a desk in a room that is 68F, and 10 minutes later it is 145F, what will the temperature be 15 minutes after you originally poured it?

Answers

To solve this problem, we can use Newton's law of cooling, which states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. We can use the formula:

T(t) = T_s + (T_0 - T_s) * e^(-kt)

where:

T(t) is the temperature of the coffee at time t

T_s is the temperature of the surroundings (68F)

T_0 is the initial temperature of the coffee (200F)

k is a constant that depends on the specific heat transfer properties of the coffee and its container

e is the mathematical constant e, approximately 2.71828

We can use the fact that the temperature is 145F after 10 minutes to find the value of k:

145 = 68 + (200 - 68) * e^(-10k)

e^(-10k) = (145 - 68) / (200 - 68) = 77 / 132

-10k = ln(77/132)

k = -ln(77/132) / 10

Now we can use this value of k to find the temperature of the coffee after 15 minutes:

T(15) = 68 + (200 - 68) * e^(-k*15)

T(15) = 68 + (200 - 68) * e^(-15ln(77/132)/10)

T(15) = 111.72

Therefore, the temperature of the coffee 15 minutes after it was poured would be approximately 111.72F.

Answer:

127 F

Step-by-step explanation:

we will use newton's law of cooling to understand the  process. Since the coffee here is losing heat so the heat loss will be proportional to the temperature difference

Determine the measure of each arc.

Answers

The measure of the arc angles which subtends angles at the center are: MN = 72°, NQR = 180°, NQ = 108°, MRP = 193°, QR = 72, MR = 108, QMR = 288°, PQ = 13°, PRN = 265°, and MQN = 288°.

What is angle subtended by an arc at the center

The angle subtended by an arc of a circle at it's center is twice the angle it substends anywhere on the circles circumference. Also the arc measure and the angle it subtends at the center of the circle are directly proportional.

So;

arc angle MN = 72° {vertical angles}

arc angle NQR = 95 + 13 + 72 = 180°

arc angle NQ = 95 + 13 = 108°

arc angle MRP = 108 + 72 + 13 = 193°

arc angle QR = 72

arc angle MR = 95 + 13 = 108 {vertical angles}

arc angle QMR = 180 + 108 = 288°

arc angle PQ = 13° {sum of angles on a straight line}

arc angle PRN = 85 + 108 + 72 = 265°

arc angle MQN = 180 + 12 + 95 = 288°.

Therefore, the following are measures of the arc angles which subtends angles at the center: MN = 72°, NQR = 180°, NQ = 108°, MRP = 193°, QR = 72, MR = 108, QMR = 288°, PQ = 13°, PRN = 265°, and MQN = 288°.

Answers

We will use Sine Law to find the third side and then according to measurements we will draw the triangle.

Given that a triangle has two sides of length 5 cm and 7 cm with an angle of 35°, [check the figure attached]

Using the Sine Law,

Sin A / BC = Sin C / AB

Sin 35° / 7 = Sin C / 5

Sin C = Sin 35° / 7 × 5

Sin C = 0.4096

C ≈ 24°

Using the angle sum property of a triangle we get the angle B = 121°.

Again, using the Sine Law,

Sin B / a = Sin C / 5

Sin 121° / a = Sin 24° / 5

a = Sin 121° × 5 / Sin 24°

a = 10.53

3. On January 1, 2022, a company purchased equipment for 100,000. The equipment is expected to have a four-year life,
with a residual value of $8,000 at the end of four years. Using the double-declining balance method, calculate the annual
depreciation for the four-year life of the equipment using the depreciation schedule below.

Answers

The double-declining balance method calculates depreciation by taking twice the straight-line depreciation rate for the first year and applying it to the book value of the asset at the beginning of the year. Here is the depreciation schedule for the four-year life of the equipment:

Year 1: Depreciation rate = 2 / 4 = 50%
Depreciation expense = 50% x $100,000 = $50,000
Book value at end of year = $100,000 - $50,000 = $50,000

Year 2: Depreciation rate = 2 / 4 = 50%
Depreciation expense = 50% x $50,000 = $25,000
Book value at end of year = $50,000 - $25,000 = $25,000

Year 3: Depreciation rate = 2 / 4 = 50%
Depreciation expense = 50% x $25,000 = $12,500
Book value at end of year = $25,000 - $12,500 = $12,500

Year 4: Depreciation rate = 2 / 4 = 50%
Depreciation expense = 50% x $12,500 = $6,250
Book value at end of year = $12,500 - $6,250 = $6,250

At the end of year 4, the book value of the equipment is equal to the residual value of $8,000, so we do not depreciate beyond that point. Therefore, the annual depreciation for the four-year life of the equipment is:

Year 1: $50,000
Year 2: $25,000
Year 3: $12,500
Year 4: $6,250

The total depreciation over the four years is $94,750.

How long would it take to pay off a $1000 balance with an interest rate of 14% APR when you only make the minimum payments of $20 each month?

3 months
1 year
3 years
6 years

Answers

To calculate how long it would take to pay off a $1000 balance with an interest rate of 14% APR when making minimum payments of $20 each month, we need to consider the monthly interest and the decreasing balance.

First, let's calculate the monthly interest. The annual interest rate is 14%, so the monthly interest rate would be 14% divided by 12 months, which is approximately 1.167%.

Now, let's determine how much of the minimum payment goes towards interest each month. The remaining amount after deducting the interest is used to decrease the balance.

In the first month, the interest on the $1000 balance would be 1.167% of $1000, which is approximately $11.67. So, after making a $20 minimum payment, $11.67 is subtracted from the balance, resulting in a new balance of $988.33.

In the subsequent months, the same process is repeated. The interest is calculated based on the new balance, and the minimum payment is made. This continues until the balance reaches zero.

Given the small minimum payment of $20 and the interest accumulating on the balance, it would take significantly longer than 3 months, 1 year, or 3 years to pay off the $1000 balance. Therefore, the correct option is 6 years.

Density of Saturn:

Answers

Answer:

Sure, I can help you with that.

To calculate the density of Saturn, we can use the following formula:

Density = Mass / Volume

We know the mass of Saturn is 5.68 x 1026 kg, and we can calculate the volume of Saturn using the following formula:

Volume = (4/3)πr³

where π is approximately equal to 3.14159 and r is the radius of Saturn, which is 5.6 x 107 m.

Plugging in these values, we get the following:

Density = 5.68 x 1026 kg / (4/3)π(5.6 x 107 m)³

Density = 0.687 kg/m³

Therefore, the density of Saturn is 0.687 kg/m³, which is less than the density of water (997 kg/m³). This means that Saturn would float on water.

Number graph |x-2|>3

Answers

The solution set for the inequality |x-2|>3 is x < -1 or x > 5, represented by the union of the open intervals (-∞, -1) and (5, ∞) on the number line.

To graph the inequality |x-2| > 3 on a number line, we can start by finding the values of x that satisfy the inequality:

|x-2| > 3

x-2 > 3 or x-2 < -3

x > 5 or x < -1

This means that any value of x that is greater than 5 or less than -1 will satisfy the inequality.

On a number line, we can mark -1 and 5 with open circles to indicate that they are not included in the solution set, and shade the regions to the left of -1 and to the right of 5 to show that any value in those regions satisfies the inequality.

The graph should look like this:

         <=========(================>)=========

         -1       2               5

The open circles at -1 and 5 indicate that those values are not included in the solution set, while the shaded regions to the left of -1 and to the right of 5 indicate that any value in those regions satisfies the inequality.

The perimeter of the hollow space is 14 cm².

We have,

From the figure,

We see that the hollow space is a rectangle.

Now,

We see that,

The length of the hollow space is the side of one square.

The width of the hollow space is also the side of another square.

So,

The rectangles dimensions:

Length = 3 cm

Width = 4 cm

The perimeter of the hollow space.

= 2 (length + width)

= 2 (3 + 4)

= 2 x 7

= 14 cm²

what is the surface area for this figure

Answers

The surface area of the triangular prism is 313.47 cm².

Given is a triangular prism, we need to find the surface area,

A triangular prism is a 3D shape with two identical faces in the shape of a triangle connected by three rectangular faces. The rectangular faces are referred to as the lateral faces, while the triangular faces are called bases. The bases are also called the top and the bottom (faces) of the prism.

Triangular Prism Meaning: A triangular prism is a 3D polyhedron with three rectangular faces and two triangular faces. The 2 triangular faces are congruent to each other, and the 3 lateral faces which are in the shape of rectangles are also congruent to each other. Thus, a triangular prism has 5 faces, 9 edges, and 6 vertices. Observe the following image of a triangular prism in which l represents the length of the prism, h represents the height of the base triangle, and b represents the bottom edge of the base triangle.

so, the surface area of a triangular prism =

perimeter × length + 2 × base area

So,

SA = (4.5+7.2+9) × 8.1 + 2 × 8.1 × 9

= 167.67 + 145.8

= 313.47

Hence the surface area of the triangular prism is 313.47 cm².

Answers

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

How is the depreciation expense per mile determined?

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)
