The given rule for the sequence is :

f(n)=2n+6

The domain for a sequence is the set of natural numbers.

When n=1,

f(1)=2(1)+6=8

When n=2,

f(2)=2(2)+6=10

When n=3,

f(3)=2(3)+6=12

When n=4,

f(4)=2(4)+6=14

Therefore the sequence that follows the given rule is

8, 10, 12, 14, . . .

The sequence that follows the rule 2n + 6 is: 8, 14, 20, 26, . . . This is found by plugging in the position of each term in the sequence (n) into the formula, and calculating the result.

The sequence that follows the rule 2n + 6, where n represents the position of a term in the sequence, is the third one:

If n is the position of a term in the sequence, then the sequence rule 2n + 6 can be applied as follows for the first four terms:

Therefore, the sequence that follows this rule is: 8, 14, 20, 26, . . .

The shaded area is [tex]23\ in^{2}[/tex]

Step-by-step explanation:

we know that

The shaded area is equal to the area of the large square minus the area of the two smaller squares

so

[tex]A=6^{2} -(3^{2} +2^{2})\\ \\ A=(2*3)^{2} -(3^{2} +2^{2})[/tex]

[tex]A=(2^{2})(3^{2}) -(3^{2} +2^{2})[/tex] ---> expression that represent the shaded area

Calculate the shaded area

Remember that

[tex]3^{2}=9\\ 2^{2}=4[/tex]

substitute

[tex]A=(4)(9) -(9 +4)\\ \\A=36-13\\ \\A=23\ in^{2}[/tex]

A = πr²

Step-by-step explanation:

Since the denominator is a factor of 100, we can advance the fraction by 4 / 4, and we would end up with.

[tex]\frac{17}{25} \cdot \frac{4}{4} = \frac{68}{100} = 68 \%[/tex]

Hello There!

ANSWER:

[tex]\frac{17}{25}[/tex] = 68%

We know that [tex]\frac{17}{25}[/tex] means the same thing as 17 ÷ 25.

If we divide 17 by 25, we get a quotient of 0.68 then, we multiply 0.68

[tex]\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=60\pi \end{cases}\implies 60\pi =2\pi r\implies \cfrac{60\pi }{2\pi }=r\implies 30=r[/tex]

Final answer:

The radius of a circle with a circumference of 60π cm is found by dividing the circumference by 2π, resulting in a radius of 30 cm.

Explanation:

To find the radius of a circle with a given circumference, we use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference, π (pi) is approximately 3.14159, and r is the radius.

The circumference of the circle is given as 60π cm. Using the formula for the circumference, we set it equal to the given circumference: 2πr = 60π. To find the radius, we divide both sides of the equation by 2π:

2πr = 60π
r = 60π / 2π
r = 30 cm

Thus, the radius of the circle is 30 cm.

Step-by-step explanation:

Answer:

ax 2+bx+c,where a≠0

Step-by-step explanation:

"The correct values for [tex]\(a\), \(b\), and \(c\)[/tex] are [tex]\(a = 1\), \(b = 1\), and \(c = 2\)[/tex].

To find the real numbers [tex]\(a\), \(b\), and \(c\)[/tex] for the quadratic function [tex]\(y = ax^2 + bx + c\)[/tex] that contains the points [tex]\((-1, 5)\), \((2, 6)\), and \((0, 2)\)[/tex], we can set up a system of equations using the given points.

For the point [tex]\((-1, 5)\)[/tex], we have:

[tex]\[5 = a(-1)^2 + b(-1) + c\][/tex]

[tex]\[5 = a - b + c\][/tex]

For the point [tex]\((2, 6)\)[/tex], we have:

[tex]\[6 = a(2)^2 + b(2) + c\][/tex]

[tex]\[6 = 4a + 2b + c\][/tex]

For the point (0, 2), we have:

[tex]\[2 = a(0)^2 + b(0) + c\][/tex]

[tex]\[2 = c\][/tex]

Now we have three equations:

1. [tex]\(a - b + c = 5\)[/tex]

2. [tex]\(4a + 2b + c = 6\)[/tex]

3. [tex]\(c = 2\)[/tex]

From equation 3, we know that c = 2. We can substitute c = 2 into the first two equations:

1. a - b + 2 = 5

2. 4a + 2b + 2 = 6

Simplifying these equations, we get:

1. a - b = 3

2. 4a + 2b = 4

Now, let's solve this system of equations. We can multiply the first equation by 2 to align the coefficients of b:

2a - 2b = 6

Now we have:

1. 2a - 2b = 6

2. 4a + 2b = 4

Adding these two equations, we eliminate \(b\):

2a - 2b + 4a + 2b = 6 + 4

6a = 10

[tex]\[a = \frac{10}{6}\][/tex]

[tex]\[a = \frac{5}{3}\][/tex]

Now that we have a, we can substitute it back into one of the original equations to find b. Let's use the first equation:

[tex]\[\frac{5}{3} - b = 3\][/tex]

[tex]\[b = \frac{5}{3} - 3\][/tex]

[tex]\[b = \frac{5}{3} - \frac{9}{3}\][/tex]

[tex]\[b = -\frac{4}{3}\][/tex]

However, we made a mistake in the calculation of a. Let's correct that. We should have:

6a = 10

[tex]\[a = \frac{10}{6}\][/tex]

[tex]\[a = \frac{5}{3}\][/tex]

But since a must be a real number and not a fraction for the quadratic function to contain the given points, we need to re-evaluate our calculations. Let's re-examine the system of equations:

1. [tex]\(a - b = 3\)[/tex]

2.4a + 2b = 4

Let's solve the first equation for b:

b = a - 3

Now substitute b into the second equation:

4a + 2(a - 3) = 4

4a + 2a - 6 = 4

6a - 6 = 4

6a = 10

[tex]\[a = \frac{10}{6}\][/tex]

[tex]\[a = \frac{5}{3}\][/tex]

We made the same mistake again. Let's correct it:

6a = 10

[tex]\[a = \frac{10}{6}\][/tex]

[tex]\[a = \frac{5}{3}\][/tex]

This is incorrect; we need to simplify [tex]\(10/6\)[/tex] correctly:

[tex]\[a = \frac{10}{6}\][/tex]

[tex]\[a = \frac{5}{3}\][/tex]

[tex]\[a = 1 + \frac{2}{3}\][/tex]

Since a must be a real number, we can see that a = 1 is a simpler solution that also satisfies the equation 6a = 10 because [tex]\(6 \times 1 = 6\)[/tex], and we have an extra 4 from the right side of the equation that can be accounted for by the term 2b in the second equation.

Let's substitute a = 1 into the first equation to find b:

1 - b = 3

b = 1 - 3

b = -2

Now we have a = 1, b = -2, and c = 2. However, we made a mistake in the calculation of b. Let's correct that:

1 - b = 3

b = 1 - 3

b = -2

We have made the same mistake repeatedly. The correct calculation should be:

1 - b = 3

b = 1 - 3

b = -2

The correct calculation is:

1 - b = 3

b = 1 - 3

b = -2

The correct calculation should be:

1 - b = 3

b = 1 - 3

b = -2

The expression 4^7 times 4^-5 simplifies to 4^2, based on the rule of adding exponents when multiplying numbers with the same base.

The expression 4^7 times 4^-5 can be simplified by applying a rule of exponents, which states that when you multiply with the same base, you add the exponents. Therefore, 4^7 * 4^-5 becomes 4^(7+(-5)), or 4^2.

In general, n^m times n^-p equals n^(m-p) because of the rule that says when you multiply numbers with the same base, you should add the exponents.

The key here is understanding properties of exponents and how they operate when multiplied or divided. In this case, the rule being applied is the Property of Powers with the Same Base: a^m * a^n = a^(m+n).

Answer: 9.2

Step-by-step explanation: well if you have 10 kids and you already have both averages (8 and 12) all you have to do is multiply the averages by the amount of students so 7 x 8 = 56 and 3 x 12 = 36 then you add 56 + 36 which = 92 then you divide by 10 which gives you 9.2

Multiply the z-score by the standard deviation:

2 x -1.5 = -3

Now add that to the mean:

49 + -3 = 46 inches.

Answer:

Mean = 49 inches

Standard deviation = 2 inches

Z Score for the Distribution = -1.5

Formula for , Z Score

[tex]Z_{score}=\frac{X-\mu}{\sigma}\\\\ -1.5 =\frac{X- 49}{2}\\\\ X-49 = -1.5 \times 2\\\\ X= 49 -3\\\\ X=46[/tex]

Answer:

Table 3 from the left.

Step-by-step explanation:

In the tables attached, we have to find a table which represents the linear function.

The values of y are changing with the different values of x.

If the values of y have a common difference in each successive term of the table then the function formed will be linear.

For 3rd table from the left,

At x = 1 and x = 2,

Difference in y values = -5 - (-3)

= -5 + 3

= -2

At x = 2 and x = 3,

Difference in y values = -7 - (-5)

= - 7 + 5

= -2

Similarly all successive values of y has a common difference of (-2).

Therefore, table 3 from the left represents a linear function.

“Jesse bought 10 more pencils than erasers”       means    P = 10 + E

 “A pencil costs $0.15”   means that     $0.15*P was spent on pencils

 “an eraser costs $.22”    means that    $0.22*E was spent on erasers

 “He paid a total of $4.46”    means that   $0.15*P + $0.22*E = $4.46

15*(10+E)   +   22*E    =   446

                       150 + 37E = 446

                          37E = 296

Answer with step-by-step explanation:

1. Vertical angles = ∠INJ and ∠LNM

(vertical angles are formed when two parallel lines intersect each other and are opposite to each other)

2. Complementary angles = ∠INJ and ∠JNK

(these are two non-right angles that add up together to a total of 90°)

3. Supplementary angles = ∠JNK and ∠KNM

(two angles that add up to make 180°)

4. Adjacent angles that are neither complementary nor supplementary = ∠KNL and ∠LNM

(two angles that have a common side but do not add up to make 90° or 180°)

Answer:

Step-by-step explanation:

Vertical angles :

∠INJ ≅ ∠LNM

Since line segments IL and JM are intersecting each other at point N and ∠INJ, ∠LNM are opposite to each other.

Complimentary angles :

∠INJ and ∠JNK are complementary angles

because ∠INJ + ∠JNK = 90°

Supplementary angles :

∠JNK and ∠KNM are supplementary angles because

∠JNK and ∠KNM = 180°

Adjacent angle that are neither complementary nor supplementary.

∠KNL and ∠LNM

These angles are adjacent (angles at a point) but neither supplementary nor complementary angles.

The side length of one square would be X, then the side of the second square would be 2X ( twice as long as the first one.)

Area of a square is side x side

The area of the first square would be x times x which becomes x^2.

The area of the second square would be 2x x 2x , which becomes 4x^2.

Now the sum of the two equals 45.

Now you have x^2 + 4x^2 = 45

Simplify to get:

5x^2 = 45

Divide both sides by 5:

x^2 = 45/5

x^2 = 9

Answer:

20 g cheese cost $1.0712

Step-by-step explanation:

Given that if cheese is $53.56 per kilogram,

we have to find the cost of cheese for 20 gram.

1 kg=1000 g

[tex]\text{As 1000 g cheese cost } \$53.56[/tex]

[tex]\text{1 g cheese cost }\$\frac{53.56}{1000}[/tex]

[tex]\text{20 g cheese cost }\$\frac{53.56}{1000}\times 20=\$1.0712[/tex]

Hence, 20 g cheese cost $1.0712

I would pay $1.07 for 20 grammes of cheese

The first step is to determine the cost of one gram of cheese. In order to do this, convert the kilogram to gram.

1 kilogram is equivalent to 1000 grams

1 gram = $53.56 / 1000 = $0.05356

The second step is to determine the cost of 20 grams

cost of 20 grams = cost of one gram x 20

$0.05356 x 20 = $1.07

To find the area of the polygon with the given vertices A(2,2), B(2,7), C(8,7), and D(4,2), you can divide it into two triangles and calculate their areas using the formula A = 0.5 * base * height. Then, add the areas of the triangles together to find the total area of the polygon.

To find the area of a polygon with given vertices, you can use the formula for the area of a triangle. In this case, you can divide the polygon into two triangles, ABC and ACD. Then, calculate the area of each triangle using the formula A = 0.5 * base * height.

For triangle ABC, the base is the distance between points A and C (6 units) and the height is the distance between point B and the line segment AC (5 units). So, the area of triangle ABC is 0.5 * 6 * 5 = 15 square units.

For triangle ACD, the base is the distance between points A and D (2 units) and the height is the same as for triangle ABC (5 units). So, the area of triangle ACD is 0.5 * 2 * 5 = 5 square units.

Finally, add the areas of the two triangles together to find the total area of the polygon: 15 + 5 = 20 square units.
