The required, in 2007 the price per gallon was 7b more than the price of a gallon of fuel in the year 2000. Where b is the inflation factor.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let 'a' be the cost per gallon of fuel in the year 2000, and 'b' be the inflation rate per year. If the rate of inflation is constant then
After 7 year inflation = 7b
Cost of fuel in 2007 = a + 7b

Now,
according to the question
Change in cost of fuel
= cost in 2007 - cost in 2000
= a + 7b - a
= 7b

The radian is a unit of measure for angles used mainly in trigonometry. ... Whereas a full circle is 360 degrees, a full circle is just over 6 radians. A full circle has 2π radians (Roughly 6.28) As seen in the figure above, a radian is defined by an arc of a circle.

The area of the bounded region is 946.46 square units (rounded to two decimal places).

To find the area of the region bounded by the curves, we need to find the points of intersection between the curves.

Setting the two equations equal to each other gives:

110x² = x

Simplifying:

110x² - x = 0

Factor out x:

x(110x - 1) = 0

Solve for x:

x = 0 or x = 1/110

So the two curves intersect at x=0 and x=1/110.

To find the area, we integrate y=110x² from x=-4 to x=1/110 and y=x from x=1/110 to x=8.

∫(110x²) dx from x=-4 to x=1/110 + ∫x dx from x=1/110 to x=8

= (110/3)(1/110)³ - (-4)(110) + (1/2)(8²) - (1/2)(1/110)²

The number of different sandwich possibilities is 1081.

To calculate this, we must use the multiplication principle. We will begin by calculating the number of possibilities for the bread, meat, and cheese. There are 6 different breads, 4 different meats, and 4 different cheeses. So, there are 6 x 4 x 4 = 96 possible combinations for the bread, meat, and cheese. Next, we must calculate the number of possibilities for the condiments. Since we are allowing repetition for the condiments, we can calculate the possibilities by multiplying 12 (the number of condiments) by itself. So, there are 12 x 12 = 144 possibilities for the condiments. Lastly, we can multiply 96 (the number of bread, meat, and cheese combinations) by 144 (the number of condiment combinations). This yields 1081 different sandwich possibilities.

The selection depends on individual needs, preferences, and the intended use of the tiny house.

a) To find the amount of space inside each house, we need to calculate the volume for each design.

House on the left:

Volume = length x width x height = 2.5 m x 18 m x 2.8 m = 126 m³

Triangular house:

Volume of a triangular prism = (base area x height) / 2

Base area = (1/2) x base x height = (1/2) x 4 m x 10 m = 20 m²

Volume = (20 m² x 7 m) / 2 = 70 m³

b) When comparing the environmental impacts of each house, several factors need to be considered:

Positive impacts:

1. Material usage: Tiny houses use fewer materials, reducing resource consumption and waste generation.

2. Energy efficiency: Smaller living spaces require less energy for heating, cooling, and lighting, leading to lower energy consumption.

3. Land utilization: Tiny houses can be built on smaller plots of land, preserving green spaces and reducing urban sprawl.

Negative impacts:

1. Construction materials: Although tiny houses use less material overall, the environmental impact depends on the types of materials used. Sustainable and eco-friendly materials should be prioritized.

2. Water and waste management: Adequate provisions for water supply and waste disposal should be implemented to minimize environmental impacts.

3. Transportation: The transportation of tiny houses to their locations can contribute to carbon emissions if not done efficiently.

c) The choice of design for a tiny house depends on personal preferences and priorities. However, considering the provided information:

The house on the left offers a larger interior space of 126 m³, providing more room for living and storage. It may be suitable for individuals or couples who desire more space and functionality within their tiny house.

The triangular house has a smaller interior volume of 70 m³ but offers a unique design and aesthetic appeal. It may be preferred by individuals who prioritize a distinctive architectural style or who are looking for a minimalist and cozy living space.

Ultimately, the selection depends on individual needs, preferences, and the intended use of the tiny house. Factors such as lifestyle, desired amenities, and personal values regarding sustainability and resource conservation should be considered when making the final decision.

Answer:

(2.57, -0.07)

Step-by-step explanation:

To solve the system of equations, we can substitute the expression for y in the second equation:

-5x + 4(1/8x - 1) = -13

We can then simplify and solve for x:

-5x + (1/2)x - 4 = -13

-3.5x = -9

x = 2.57

We can then substitute this value of x back into the first equation to find the value of y:

y = 1/8(2.57) - 1

y = -0.07

So the solution of the system of equations is (x, y) = (2.57, -0.07)

a) The probability that both the husband and the wife will be audited is 0.04.

b) The probability that only one of them will be audited is 0.32.

c) The probability that neither one of them will be audited is 0.36.

d) The probability that at least one of them will be audited is 0.36.

(a) The probability that both the husband and the wife will be audited is calculated by multiplying the probability that the husband will be audited by the probability that the wife will be audited. Since the audits are assumed to be independent, we can use the multiplication rule of probability:

P(both audited) = P(husband audited) x P(wife audited)

= 0.2 x 0.2

= 0.04

(b) The probability that only one of them will be audited can be calculated in two ways: either the husband is audited and the wife is not, or the wife is audited and the husband is not. Since these events are mutually exclusive, we can use the addition rule of probability:

P(one audited) = P(husband audited and wife not audited) + P(wife audited and husband not audited)

= (0.2 x 0.8) + (0.8 x 0.2)

= 0.32

(c) The probability that neither one of them will be audited is the complement of the probability that at least one of them will be audited. Using the complement rule of probability, we can write:

P(neither audited) = 1 - P(at least one audited)

We can find the probability that at least one of them will be audited by subtracting the probability that neither of them will be audited from 1. So:

P(at least one audited) = 1 - P(neither audited)

= 1 - (0.8 x 0.8)

= 0.36

(d) The probability that at least one of them will be audited is 0.36, as we found in part (c).

The discontinuity is the value of x or y for which the function is not defined. It is represented by a blank dot at the point at which it is not defined.

The discontinuity of the function is represented by a blank dot, and it is the point where the function is not defined.

If we look in the graph, we will find that there are three blank dots, which are at:

x = -2

x = 0

x = 4

Now, since discontinuity means that the function is not defined but as we can see that the value of the function is defined at x = -2, therefore, we are left with only two options which are x=0 and x=4.
