The common ratio of the resulting sequence is 1.4.

Given that, the three terms are 60, 100 and 180.

A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant. This ratio is known as a common ratio of the geometric sequence.

Let the same constant is added to the given number is x.

60+x, 100+x and 180+x

Now, the common ratio is

(100+x)/(60+x) = (180+x)/(100+x)

⇒ (100+x)(100+x)=(180+x)(60+x)

⇒ (100+x)²=10800+180x+60x+x²

⇒ 10000+200x+x²=10800+180x+60x+x²

⇒ 10000+200x=10800+180x

⇒ 20x=800

⇒ x=40

The three number are 100, 140 and 220

The common ratio is 140/100 =1.4

(5u - 15) - 3 = (18u - 12) - 3u

5u - 18 = 15u - 12

-18 = 10u - 12

-6 = 10u

u = -6/10

u = -3/5

The numeric value of the exponential expression in this problem is given by the following option:

A. 2^12.

The exponential expression for this problem is defined as follows:

8^x/2^y.

8 is the third power of 2, hence:

8 = 2^3.

When a term is elevated to two of it's powers, the powers are multiplied, hence:

(2^3)^x = 2^(3x).

Meaning that the exponential expression is then written as follows:

8^x/2^y = 2^(3x)/2^y.

When two terms of the same base and different exponents are divided, we keep the base and subtract the exponents, hence the expression is given as follows:

2^(3x)/2^y = 2^(3x - y).

As stated in the problem, the numeric value of the expression 3x - y is given as follows:

3x - y = 12.

Hence the entire expression is simplified as follows:

2^(3x - y) = 2^12.

Meaning that the correct option is given by option A.

Step-by-step explanation:

To find the fraction of pocket money left after spending on transport and fruit, we need to subtract the amount spent from the total pocket money and express it as a fraction.

The student spends 18 out of 35 of his pocket money, which means he has (35 - 18) = 17 units of his pocket money left.

Therefore, the fraction of pocket money left can be written as 17/35.

Therefore, the perimeter of triangle DAB is 53.5 units. Therefore, the area of triangle DAB is 45 square units.

Area is a measure of the size of a two-dimensional surface or region. It is the amount of space inside the boundary of a flat object or shape, typically measured in square units such as square inches or square meters. The formula for finding the area of various shapes may differ, but in general, it involves multiplying the length and width, or base and height, or using other specific formulas depending on the shape.

Here,

To find the perimeter of triangle DAB, we need to calculate the lengths of the three sides and add them up:

AB = √[(x_B - x_A)² + (y_B - y_A)²]

= √[(-1 - (-18))² + ((-1) - (-1))²]

= √(289)

= 17

AD = √[(x_D - x_A)² + (y_D - y_A)²]

= √[(-10 - (-18))² + (9 - (-1))²]

= √(400)

= 20

BD = √[(x_B - x_D)² + (y_B - y_D)²]

= √[(-1 - (-10))² + ((-1) - 9)²]

= √(121 + 100)

= √(221)

Therefore, the perimeter of triangle DAB is:

Perimeter = AB + AD + BD = 17 + 20 + √(221) ≈ 53.5

To find the area of triangle DAB, we can use the following formula:

Area = 1/2 * |(x_A - x_D)(y_B - y_D) - (x_B - x_D)(y_A - y_D)|

Substituting the coordinates of the three vertices, we get:

Area = 1/2 * |(-18 - (-10))(-1 - (-1)) - (-1 - (-10))(9 - (-1))| = 1/2 * |(-8)(0) - (-9)(10)|

= 45

It will take 3.5 hours for the two cars to be 280 miles apart.

To determine the time it takes for the two cars to be 280 miles apart, we can use the concept of relative velocity.

Since the cars are traveling in opposite directions, their velocities can be added together to find their relative velocity:

Relative velocity = Velocity of car traveling east + Velocity of car traveling west

Relative velocity = 60 mph + 20 mph

Relative velocity = 80 mph

The relative velocity of the cars is 80 mph, which means that they are moving away from each other at a combined speed of 80 mph.

To find the time it takes for them to be 280 miles apart, we can use the formula:

Time = Distance / Speed

Plugging in the values, we have:

Time = 280 miles / 80 mph

Time = 3.5 hours

Therefore, it will take 3.5 hours for the two cars to be 280 miles apart.

During this time, the car traveling east would have covered a distance of 60 mph × 3.5 hours = 210 miles, while the car traveling west would have covered a distance of 20 mph × 3.5 hours = 70 miles.

The sum of these distances is indeed 280 miles, confirming the result.

Answer:

x=0.5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    Divide both sides of the equation by 2:

                    x = 1/2 = 0.500

Answer: To solve this expression, we first need to simplify the terms in the denominator:

5 1/3 - 4 2/3 + 1 1/6 x 2

We can convert each fraction to a mixed number:

5 1/3 = 5 + 1/3

4 2/3 = 4 + 2/3

1 1/6 x 2 = 2 x 1/6 + 2 = 2 + 1/3

Now we can perform the subtraction:

(5 + 1/3) - (4 + 2/3) + (2 + 1/3)

= 5 + 1/3 - 4 - 2/3 + 2 + 1/3

= 5 + 1/3 - 4 + 2 + 1/3 + 1/3

= 7

So the denominator simplifies to 7.

Next, we simplify the numerator:

8 - (2/3)^2

We can first square the fraction:

(2/3)^2 = 4/9

Now we can perform the subtraction:

8 - 4/9

= 8 - 4/9

= 8 x 9/9 - 4/9

= 72/9 - 4/9

= 68/9

So the numerator simplifies to 68/9.

Finally, we divide the numerator by the denominator:

68/9 ÷ 7 = 9.71

So, the expression simplifies to 9.71.

Step-by-step explanation:

The equation of the line in slope-intercept form is y = (3/5)x + 2. This form allows us to easily identify the slope and y-intercept of the line and to graph it on a coordinate plane.

To write the equation of a line in slope-intercept form, we use the formula:y = mx + b

where:

- y represents the dependent variable (the vertical axis)

- x represents the independent variable (the horizontal axis)

- m represents the slope of the line

- b represents the y-intercept, the point where the line intersects the y-axis.

In this case, we are given the slope as 3/5 and the y-intercept as 2. Plugging these values into the formula, we get:

y = (3/5)x + 2

This equation represents a line with a slope of 3/5, indicating that for every 5 units we move horizontally (along the x-axis), the line moves 3 units vertically (along the y-axis). The y-intercept of 2 tells us that the line intersects the y-axis at the point (0, 2).

To calculate the prorations for interest and property taxes, we need to determine the number of days each party (the buyer and the seller) will own the property during the month of June.

There are a total of 30 days in June, so the seller will own the property for 15 days (from June 1 to June 15), and the buyer will own the property for 15 days (from June 16 to June 30).

Prorations for Interest:

The annual interest rate is 8%, which means the monthly interest rate is 8%/12 = 0.6667%. To calculate the daily interest rate, we divide the monthly interest rate by 30 (the number of days in June):

0.6667% / 30 = 0.0222%

The total interest owed for the full month is:

$168,745.60 x 0.6667% = $1,124.28

To calculate the prorated interest for the seller, we multiply the daily interest rate by the number of days the seller owned the property:

0.0222% x $168,745.60 x 15 = $559.02

To calculate the prorated interest for the buyer, we multiply the daily interest rate by the number of days the buyer will own the property:

0.0222% x $168,745.60 x 15 = $559.02

Therefore, the total prorations for interest are:

$559.02 for the seller and $559.02 for the buyer.

Prorations for Property Taxes:

To calculate the prorated property taxes, we divide the annual taxes by 365 (the number of days in a year) to get the daily tax rate:

$3,893.25 / 365 = $10.66 per day

To calculate the prorated property taxes for the seller, we multiply the daily tax rate by the number of days the seller owned the property:

$10.66 x 15 = $159.90

To calculate the prorated property taxes for the buyer, we multiply the daily tax rate by the number of days the buyer will own the property:

$10.66 x 15 = $159.90

Therefore, the total prorations for property taxes are:

$159.90 for the seller and $159.90 for the buyer.

The prorations will be subtracted from the seller's equity because they represent expenses incurred by the seller during the time they owned the property.

The maximum number of pieces of drywall that can be installed before running out of screws is 0.

To determine the number of pounds of drywall that can be installed before running out of screws, we need to consider the weight of both the drywall and the screws.

Given:

12 screws are required per piece of drywall.

Each piece of drywall weighs 30 lbs.

Each screw weighs 0.011 lbs.

The company received a bulk order of 100 lbs of screws.

Let's denote the number of pieces of drywall as "x".

The weight of the screws can be calculated as:

Weight of screws = Number of screws × Weight per screw

Weight of screws = 12 screws × 0.011 lbs/screw

Weight of screws = 0.132 lbs

Now, we can calculate the maximum number of pieces of drywall that can be installed based on the weight of the screws:

Maximum number of pieces of drywall = Weight of screws / Weight per drywall piece

Maximum number of pieces of drywall = 0.132 lbs / 30 lbs

Maximum number of pieces of drywall ≈ 0.0044 pieces

Since it doesn't make sense to have a fraction of a drywall piece, we can round down the result. Therefore, the maximum number of pieces of drywall that can be installed before running out of screws is 0.

In conclusion, with the given bulk order of 100 lbs of screws, the company cannot install any drywall before running out of screws.

The scale factor used to draw is 1/60 thus the area in feet² is 108000 feet².

You must specify the extent of the shape's enlargement when describing one.

The scale factor is the ratio of two dimensions such that one figure is large and another is small.

Length in drawing = 6 inhces

Width in drawing = 5 inches

Width in real = 300 feet = 3600 inches

Scale factor = 5/3600 = 1/720

Length in real = 6/(1/720) = 4320 inches

4320/10 = 360 feet

Width in real = 5/(1/720) = 3600 inches

3600/12 = 300 feet

Area in real = 360 × 300

⇒ 108000 feet²

Hence "The scale factor used to draw is 1/60 thus the area in feet² is 108000 feet²".

They can buy 120 vans, 60 small trucks, and 80 large trucks.

The truck company plans to spend 10 million on 260 vehicles. Each commercial van cost 25,000 dollars. Each small truck 50,000 dollars and each large truck 50,000 dollars. They needed twice as many van as small truck

Therefore,

let

s = number of small truck

number of van = v

let

l = number of large truck

v + s + l = 260

25,000(v) + 50,000(s) + 50,000(l) = 10,000, 000

v + 2s + 2l = 400

Hence,

v = 2s

So,

2s + 2s + 2l = 400

4s + 2l = 400

2s + s + l = 260

3s + l = 260

2s + l = 200

s = 60

l = 200 - 2(60)

l = 200 - 120

l = 80

v = 2(600 = 120

The maximum and minimum values of the function is solved

Given data ,

We can find the maximum and minimum values of the function by taking the derivative of y with respect to x and setting it equal to zero.

y = (sin x)³ - (sin x)⁶

y' = 3(sin x)² cos x - 6(sin x)⁵ cos x

Setting y' equal to zero:

0 = 3(sin x)² cos x - 6(sin x)⁵ cos x

0 = 3(sin x)² cos x (1 - 2(sin x)³)

sin x = 0 or (sin x)³ = 1/2

If sin x = 0, then x = kπ for any integer k.

If (sin x)³ = 1/2, then sin x = (1/2)^(1/3) ≈ 0.866. This occurs when x = π/3 + 2kπ/3 or x = 5π/3 + 2kπ/3 for any integer k.

To determine whether these values correspond to a maximum or minimum, we can use the second derivative test.

y'' = 6(sin x)³ cos² x - 15(sin x)⁴ cos² x - 9(sin x)⁴ cos x + 6(sin x)⁵ cos x

y'' = 3(sin x)³ cos x (4(sin x)² - 5(sin x)² - 3cos x + 2)

For x = kπ, y'' = 3(0)(-3cos(kπ) + 2) = 6 or -6, depending on the parity of k. This means that these points correspond to a maximum or minimum, respectively.

For x = π/3 + 2kπ/3 or x = 5π/3 + 2kπ/3, y'' = 3(1/2)^(5/3) cos x (4(1/2)^(2/3) - 5(1/2)^(1/3) - 3cos x + 2). This expression is positive for x = π/3 + 2kπ/3 and negative for x = 5π/3 + 2kπ/3, which means that the former correspond to a minimum and the latter to a maximum.

Hence , the maximum value of the function is y = 27/64, which occurs at x = 5π/3 + 2kπ/3, and the minimum value is y = -1/64, which occurs at x = π/3 + 2kπ/3

Answer:

Step-by-step explanation:

You want the maximum and minimum values of the function ...

  y = sin³(x) -sin⁶(x)

When we substitute sin³(x) = z, we have the quadratic expression ...

  y = z -z² . . . . . a quadratic function

Adding and subtracting 1/4, we can put this in vertex form:

  y = -(z -1/2)² +1/4

This version of the function describes a parabola that opens downward and has a vertex at (z, y) = (1/2, 1/4). The y-value of the vertex represents the maximum value of the function.

The maximum value of y is 1/4.

The sine function is a continuous function with a range of [-1, 1]. Then z will be a continuous function of x, with a similar range. We already know that y describes a function of z that is a parabola opening downward with a line of symmetry at z = 1/2. This means the most negative value of y will be found at z = -1 (the value of z farthest from the line of symmetry). That value of y is ...

  y = (-1) -(-1)² = -1 -1 = -2

The minimum value of y is -2.
