The first 6 terms of the given sequences are  for A: 1, 2, 2, 4, 8, 16

for B: 5, 5, 17, 59, 177, 521, and for C: 2, 1, 3, 6, 15, 45

A. The 1st sequence is a geometric sequence, where each term is the product of the two preceding terms. The 1st term is 1, the 2nd term is 2, and the rest of the terms are calculated as below:

a3 = a1 * a2 = 1 * 2 = 2

a4 = a2 * a3 = 2 * 2 = 4

a5 = a3 * a4 = 2 * 4 = 8

a6 = a4 * a5 = 4 * 8 = 16

So, the first six terms of the sequence are 1, 2, 2, 4, 8, and 16.

B. The 2nd sequence can be calculated by using the formula

an = 2 * an - 1 + 3 * an - 2 for n greater than or equal to 2. The 1st term a1 is 5 and the 2nd term a2 is 5, so the rest of the terms are calculated as below:

a3 = 2 * a2 + 3 * a1 = 2 * 5 + 3 * 5 = 17

a4 = 2 * a3 + 3 * a2 = 2 * 17 + 3 * 5 = 59

a5 = 2 * a4 + 3 * a3 = 2 * 59 + 3 * 17 = 177

a6 = 2 * a5 + 3 * a4 = 2 * 177 + 3 * 59 = 521

So, the first six terms of the sequence are 5, 5, 17, 59, 177, and 521.

C. The 3rd sequence follows the formula gn = n * gn - 1 + gn - 2. The 1st term g1 is 2 and the 2nd term g2 is 1, so the rest of the terms are calculated as below:

g3 = 3 * g2 + g1 = 3 * 1 + 2 = 5

g4 = 4 * g3 + g2 = 4 * 5 + 1 = 21

g5 = 5 * g4 + g3 = 5 * 21 + 5 = 110

g6 = 6 * g5 + g4 = 6 * 110 + 21 = 786

So, the first six terms of the sequence are 2, 1, 3, 6, 15, and 45.

Gina should buy from Stickers4u.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

Gina is going to buy 100 stickers.

If she buys from the shop - Stickers4u,

then the cost is,

= 100/25 x 2.15

= 4 x 2.15

A company did a study on the physical activity level and weight gain of its employees. Age was not considered, so it might be an example of a confounding variable.

A confounding variable is an unmeasured third variable that influences, or confounds, the relationship between an independent and a dependent variable. For example, in a study looking at the relationship between smoking and lung cancer, age may be a confounding variable because people who smoke tend to be older than those who do not.

This would mean that age is influencing both smoking and the risk of lung cancer, so the true effect of smoking on the risk of lung cancer cannot be determined without taking age into account. The presence of a confounding variable can distort the results of an experiment and lead to inaccurate conclusions.

Step-by-step explanation:

There are 11 1/3 based in the area outside and the total surface area of the outside of the glass is 80.07 square inches

From the question, we have the following parameters that can be used in our computation:

Height, h = 7 inches

Radius, r = 1.5 inches

π = 3.14

The area of the base is calculated as

Base area = πr²

So, we have

Base area = π * 1.5²

Base area = 2.25π

The surface area of the outside of the glass is

Surface area = 2πr(r + h)

So, we have

Surface area = 2π * 1.5 * (1.5 + 7)

Surface area = 25.5π

The number of base is

Number = 25.5π/2.25π

Evaluate

Number = 11 1/3

In (a), we have

Surface area = 25.5π

This gives

Surface area = 25.5 * 3.14

Evaluate

Surface area = 80.07

Hence, the area is 80.07 square inches

The answer is B. diverges.

Theorem 9.11 states that if the sequence of positive terms (an) satisfies the condition 1/an^p converges, then the p-series ∑an converges if p > 1 and diverges if p ≤ 1. In this case, the positive terms of the sequence are given by [1/(n^(3/2))]. So, [1/an^p] = [1/(n^(3/2))^p] = [1/n^(3p/2)].

For the series to converge, we need [1/an^p] to converge, or [1/n^(3p/2)] to converge.

If 3p/2 > 1, then [1/n^(3p/2)] converges and the series converges.

If 3p/2 ≤ 1, then [1/n^(3p/2)] diverges and the series diverges.

So, to determine the value of p, we need to find the value of p such that 3p/2 = 1. Solving for p, we find that p = 2/3.

Since 2/3 ≤ 1, the series diverges. Therefore, the answer is B. diverges.

If the matrix xt x is not invertible, then its determinant is equal to 0. A determinant of 0 implies that the matrix is singular, meaning that its columns are linearly dependent.

This means that one of the columns of x can be expressed as a linear combination of the other columns, which implies that there is only one way in which the invertibility problem may arise: when the columns of the matrix x are linearly dependent.

If the determinant of xt x is equal to 0, then at least one column of x can be expressed as a linear combination of the others. For example, if column c can be expressed as a linear combination of columns a and b, then we can write:

c = k1a + k2b

where k1 and k2 are constants. This means that the information in column c is already represented in columns a and b, and so it is redundant.

This is the only way in which the invertibility problem of xt x may arise. If the columns of the matrix are linearly independent, then the determinant of xt x will be non-zero, and the matrix will be invertible.

For the given triangles ΔABC ≈ ΔBKJ, the value of KJ is, 9

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

The triangle, ΔABC

ΔABC has one similar triangle inside, which is ΔBKJ

Triangle ΔABC and ΔBKJ similar,

So, we can say ΔABC ≈ ΔBKJ

And it is known that

for similar triangles, ratio of lengths of sides are equal for similar triangles

so, AB/AC = KB/KJ

AB  = 2KB

⇒  2KB/18 = KB/KJ

Answer:

x = 18

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 , then

sum = 180° × 3 = 540°

sum the 5 interior angles and equate to 540

3x + 23 + 95 + 7x - 4 + 90 + 9x - 6 = 540

19x + 198 = 540 ( subtract 198 from both sides )

19x = 342 ( divide both sides by 19 )

x = 18

From the following numerical expressions given, the numerical expression which results in a positive number is (-67) - (-12).

In mathematics, subtraction is the process of finding the difference between two numbers. If two numbers have the same sign (both positive or both negative), the result of their subtraction will have the same sign as the numbers being subtracted.

However, if the numbers have different signs, the result of their subtraction will have the sign of the number with the larger absolute value. In this case, (-67) and (-12) have different signs, but (-12) has a larger absolute value than (-67). Therefore, the result of the subtraction will be positive.

In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.

Based on the sides of a triangle, a triangle is classified into 3 types, namely:

Scalene Triangle – All the sides are of different measures.

Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.

Equilateral Triangle – All the 3 sides of a triangle are of the same measure.

Based on the angles of a triangle, a triangle is classified into 3 types, namely:

Acute Angle Triangle – All the angles of a triangle is less than 90°.

Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.

Right Angle Triangle – One of the angles of a triangle is equal to 90°.

The length of the GH is 4, when H is the midpoint of GI.

An area of a line that connects two distinct locations is referred to as a line segment. It is the least path between two places that can be determined to have a length.

A line segment's midpoint is the point on the segment when it is divided into two similar segments. The point on a line segment that is equally spaced from the two terminating points is known as the midpoint of the segment.

Given that H is the midpoint of GI.

Then we can say that,

GI / 2 = GH

Substitute the equations of the length of GH and GI as given:

(9x - 19) / 2 = 3x - 5

9x - 19 = 2(3x - 5)

9x - 19 = 6x - 10

9x - 6x = -10 + 19

3x = 9

x = 3

Substitute the value of x in the equation of the length of the segment GH thus:

GH = 3x - 5

GH = (3)(3) - 5

GH = 4

Hence, the length of the GH is 4, when H is the midpoint of GI.

John's average speed for the entire trip is 50 km/h. So the minimum average speed for the entire trip would be 60 km/h.

To calculate John's average speed, we need to determine the total distance he covered and the total time he spent driving. Given that John drove 60 km/h for 2 hours in the morning, and 40 km/h for a different amount of time in the evening, we can calculate the total distance as follows:

[tex]d = 60 × 2 + 40 × T[/tex]

where T is the total time spent driving in the evening.

To find John's average speed, we need to divide the total distance by the total time:

Average speed = [tex]d / (2 + T)[/tex]

Since we do not know the value of T, we cannot determine the exact average speed. However, we can determine an upper bound on the average speed by assuming that T is 0 (i.e., John drove back to town immediately after arriving at his mother's house). In this case, John's average speed would be equal to the speed he drove in the morning, which was 60 km/h.

Hence the minimum average speed for the entire trip would be 60 km/h, and the maximum average speed would be equal to the speed he drove in the evening, which was 40 km/h. The average of these two speeds is 50 km/h.
