Step-by-step explanation:

First we recall the relevant definitions and properties:

An even integer is an integer that is a multiple of 2, that is, an integer that can be written as 2k2k where kk is also an integer.

An abelian group is a set with an operation that is closed in that set, is associative, has an identity element, has inverses, and is commutative.

Addition is already associative and commutative over the set of all integers, and has an identity 00 and an inverse −n−n for each integer nn.

Oh, and multiplication of integers distributes over addition (this is important because we’re dealing with multiples of 2 but also with addition. The distributive property is how multiplication relates to addition).

This means we have to show a few things:

Addition is closed over the even integers. This holds due to the distributive property: if you have even integers 2k2k and 2m2m, then 2k+2m=2(k+m)2k+2m=2(k+m) is also an even integer. The odd integers fail this property: for example, 11 is odd but 1+1=21+1=2, which is not odd.

Addition is associative over the even integers. This holds because addition is already associative over the set of all integers: 2k+(2m+2j)=(2k+2m)+2j2k+(2m+2j)=(2k+2m)+2j. The odd integers do satisfy associativity, since they’re also a subset of the integers.

Addition has an identity element over the even integers. Since we already know that 00 is an identity for the set of all integers and 00 is even, this shows that we have an identity for the even integers: 2k+0=2k2k+0=2k. This doesn’t hold for the set of odd integers, because if nn and kk are odd integers and n+k=nn+k=n then k=0k=0, a contradiction since 00 is not odd.

Addition has inverses over the even integers. We already know that integers have inverses, and if 2k2k is an even integer then −k−k is the inverse of kk, so that 2k+2(−k)=2(k+(−k))=2(0)=02k+2(−k)=2(k+(−k))=2(0)=0. This means the even integer 2(−k)2(−k) is the inverse of 2k2k. The odd numbers do satisfy this property, since they’re also a subset of the integers.

Addition is commutative over the even integers. This holds because addition is already commutative over the set of all integers: 2k

Answer:

(C) -6

Step-by-step explanation:

Given the following data;

Points on the graph (x1, y1) = (1, -9).

Mathematically, the equation of a straight line is given by the formula;

y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

To find the zero of the linear function f, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - (-9) = -3(x - 1)

y + 9 = -3x + 3

y = -3x + 3 - 9

y = -3x -6 = mx + c

Intercept (c) or zero of a function = -6

Answer: Steven read more pages per minute than Dana

Step-by-step explanation:

To find the distance between Basti and Cian, we can use the law of sines in triangle ABC. The law of sines states that the ratio of the length of a side to the sine of the opposite angle is constant for all sides and their corresponding angles in a triangle.

Let's label the distance between Basti and Cian as "x". We know that the measure of angle ABC is 50 degrees and the measure of angle BAC is 60 degrees. We also know that Ali is exactly 150 ft away from Basti.

Using the law of sines, we can set up the following equation:

sin(50°) / 150 = sin(60°) / x

To solve for "x", we can rearrange the equation:

x = (150 * sin(60°)) / sin(50°)

Using a calculator, we can evaluate the expression:

x ≈ (150 * 0.866) / 0.766

x ≈ 168.4 ft

Therefore, the distance between Basti and Cian is approximately 168.4 ft.

Answer:

The perimeter of the rhombus in this problem is given as follows:

19.8 units.

The perimeter of a polygon is given by the sum of all the lengths of the outer edges of the figure, that is, we must find the length of all the edges of the polygon, and then add these lengths to obtain the perimeter.

The diagonal length can be obtained as follows:

RU + UT = 7.

Applying the Pythagorean Theorem, the side length is obtained as follows:

x² + x² = 7²

2x² = 49

\(x = \sqrt{\frac{49}{2}}\)

x = 4.95.

Then the perimeter is given as follows:

P = 4 x 4.95

P = 19.8 units.

Answer:2,4

Step-by-step explanation:

To solve this problem, I need to compare the time it will take for Abiana to reach the opposite corner of the rectangular park using a scooter and walking, respectively.

First, I need to find out the distance Abiana will need to cover if she goes around the park. To do this, I can use the Pythagorean Theorem, which states that the square of the length of the hypotenuse (in this case, the distance Abiana needs to travel) is equal to the sum of the squares of the lengths of the other two sides.

So, the square of the distance Abiana needs to travel is equal to (3/4)^2 + 1^2 = 25/16, which means the distance itself is the square root of 25/16 miles, or 5/4 miles.

If Abiana takes a scooter, it will take her 8 minutes to travel 1 mile, so it will take her 8 * 5/4 = 10 minutes to travel the distance around the park.

On the other hand, if Abiana walks directly across the grass, it will take her 20 minutes to travel 1 mile, so it will take her 20 * 5/4 = 25 minutes to travel the diagonal distance of the rectangular park.

Therefore, taking the scooter is the faster mode of transportation, as it will take Abiana 10 minutes to travel the distance around the park, whereas she will need 25 minutes to walk directly across.

The equation that models the total cost C Thomas paid to rent the van, when m is greater than or equal to 3,000, is C = 0.35m - 530.

To model the total cost C that Thomas paid to rent the van, we need to consider two components: the base daily rental cost and the additional cost for the miles driven over 3,000 miles.

Let's break down the equation step by step:

The base daily rental cost is $65 per day, and Thomas rented the van for 8 days. Therefore, the base cost component is 8 * $65 = $520.

For the additional cost per mile driven over 3,000 miles, the rate is $0.35 per mile. Since m represents the number of miles driven, we subtract the threshold of 3,000 miles from m to find the number of miles over the threshold. So, the additional cost component is ($0.35) * (m - 3,000) = $0.35m - $1,050.

Combining the base cost and the additional cost, the equation that models the total cost C becomes:

C = 520 + 0.35m - 1050.

Answer:

  192 square feet

Step-by-step explanation:

You want the area of the isosceles triangle with congruent sides 20 ft and base 32 ft.

The height (h) of the triangle is one leg of a right triangle with hypotenuse 20 ft and the other leg 16 ft. It can be found using the Pythagorean theorem:

  h² +16² = 20²

  h² = 400 -256 = 144

  h = √144 = 12

Then the area of the triangle is ...

  A = 1/2bh

  A = 1/2(32 ft)(12 ft) = 192 ft²

The area is 192 square feet.

__

Additional comment

You recognize the base and hypotenuse of the right triangle have the ratio 16/20 = 4/5. This tells you that the right triangle is a 3-4-5 right triangle with a scale factor of 4. That makes the height 4·3 = 12 feet.

This recognition saves you the effort of using the Pythagorean theorem to find the same number.

Given the side lengths, you can also find the area using Heron's formula:

  A = √(s(s -a)(s -b)(s -c)) . . . . . where s=(a+b+c)/2, the semiperimeter

  A = √(36(16)(16)(4)) = 6·4·4·2 = 192 . . . . as above

Answer:

if there's a graph for f(x):

if you're given a graph it means that at the x-coordinate x=1 the corresponding y-value is y=7. Another way to think of this is it's giving you the ordered pair. f(x-value) = y-value which gives you (x,y).

if there's an equation for f(x):

if you're given an equation, you're still looking to find the y-value but instead of looking on a graph, you're plugging 1 in for x in the equation which, after solving the equation, will equal 7.

basically, at x=1, the y-coordinate is 7

Answer:

x=6

Step-by-step explanation:

This equation requires simplifying. We start with moving like terms to each other:

3 + 9 = 4/3x + 2/3x

After this, add the like terms together:

12 = 6/3x

6/3 will simplify into 2:

12=2x

Finally, divide both sides by 2:

Answer:

Step-by-step explanation:

To calculate the total balance on the next billing date, we need to consider the average daily balance and the unpaid balance from the previous month.

Given:

Average daily balance for November = $700

Unpaid balance at the end of November = $1,400

Annual percentage rate (APR) = 15.6%

Step 1: Calculate the interest charged for the month of November.

Interest = (Average daily balance * APR * Number of days in the month) / 365

Number of days in November = 30

Interest = (700 * 0.156 * 30) / 365 = $36.44 (rounded to the nearest cent)

Step 2: Add the interest to the unpaid balance to get the total balance on December 1.

Total balance = Unpaid balance + Interest

Total balance = $1,400 + $36.44 = $1,436.44

Therefore, the total balance on the next billing date, December 1, is $1,436.44 (rounded to the nearest cent).

The total balance on the next billing date December 1 is $1,509.20.

The annual interest produced by a sum that is paid to investors or charged to borrowers is referred to as the annual percentage rate (APR).

Given,

Then, the percentage rate for November = \(\sf\frac{15.6}{100}\) × 700

\(\sf = \$109.20\)

Balance on 1st December = unpaid balance at the end of November + percentage rate

\(\sf = $1400 +$109.20\)

\(\sf =\$1509.20\)

Therefore, the total balance on the next billing date December 1 is $1,509.20.
