By using properties of triangle, it can be inferred that

The value of c lies between 5 and 21 and also 5 and 21 are not included

What is a triangle?

A triangle is a three sided two dimensional figure. A triangle has three sides and three interior angles. The sum of the interior angles of a triangle is 180°

Let a = 8, b = 13 and let the third side be c

We know sum of two sides of a triangle is always greater than the third side

a < b + c

8 < 13 + c

c > 8 - 13
c > -5, which is obvious

b < c + a

13 < c  + 8

c > 13 - 8

c > 5

c < a + b

c < 8 + 13

c < 21

5 < c < 21

The value of c lies between 5 and 21 and also 5 and 21 are not included

If three pencils, each measuring one foot in length, are laid end to end touching, the total distance covered by the row would be 3 feet.

Since each pencil is 1 foot long, when three pencils are laid end to end, they form a row that is 3 feet long. The key information here is that the pencils are touching, which means there are no gaps between them. Therefore, the row would extend for a total distance of 3 feet.

In this scenario, the correct answer is option a, 3 ft. The row would not extend beyond 3 feet because there are only three pencils, each measuring one foot in length. If there were more pencils or if they were not touching end to end, the total distance covered by the row would be different. However, based on the given information, the row formed by the three one-foot-long pencils would have a length of 3 feet.

The given circle having two external tangents, according to circle

theorem, have the following values;

r² + 1.6² = (0.4 + r)²

(0.4 + r)² - (r² + 1.6²) = 0

0.8·r - 2.4 = 0

0.8·r = 2.4

r = 2.4 ÷ 0.8 = 3

The total number of left cosets of h in Z is n.

Here, Z represents the set of all integers and h = {0, 6n, 62n, 63n, . . .} is a subgroup of Z.

To find the left cosets of h in Z, we need to consider the elements of Z that are not already in h and then form the left cosets by adding elements of h to these elements.

Let's consider an integer a that is not in h. Then a can be written as:

a = 6qn + r, where 0 ≤ r < 6n

Now, we can form the left coset of h containing a by adding elements of h to a. That is:

a + h = {a + 0, a + 6n, a + 62n, a + 63n, ...}

Notice that adding any multiple of 6n to a will not change the left coset. Therefore, we can write:

a + h = {a + 6kn : k is an integer}

So, the left cosets of h in Z are of the form {6kn : k is an integer}. There are n different such cosets, because there are n different residue classes modulo 6n.

Therefore, the total number of left cosets of h in Z is n.

Note: A left coset of a subgroup H in a group G is a set of the form {ah : h ∈ H}, where a is an element of G.

The vertex of the quadratic function y = (1/2)x^2 + x + 3 is (-1, 5/2).

To find the vertex of the quadratic function y = (1/2)x^2 + x + 3, we can use the vertex formula, which states that the x-coordinate of the vertex is given by -b/2a, where the quadratic function is in the form y = ax^2 + bx + c.

In this case, the coefficient of x^2 is 1/2 (a = 1/2) and the coefficient of x is 1 (b = 1). Plugging these values into the vertex formula, we have:

x-coordinate of vertex = -b/2a = -(1)/2(1/2) = -1/(2/2) = -1/1 = -1

To find the y-coordinate of the vertex, we substitute the x-coordinate back into the quadratic function:

y = (1/2)(-1)^2 + (-1) + 3

= (1/2)(1) - 1 + 3

= 1/2 - 1 + 3

= 1/2 - 2/2 + 6/2

= 5/2

Consequently, (-1, 5/2) is the vertex of the quadratic function y = (1/2)x2 + x + 3.

So, on solving the provided question we can say that the rate of change of the volume with respect to radius = \(1770 = 4/3 \pi r^3S = 4 \pi r^2\) \(dS/dt = 8 \pi r dr/dt\)

The length of a circle or sphere, in more contemporary use, is the same as its radius in classical geometry, which is one of the line segments from its center to its circumference. The Latin word radius, which also refers to the spokes of a wagon wheel, gave rise to the term. The distance a circle's center is from any point on its perimeter is its radius. Usually, "R" or "r" is used to indicate it. A radius is a line segment that has one endpoint in the center and one on the circumference of a circle. Circular diameter equals radius The diameter of a circle is the segment that traverses its center and has ends that are on the circle.

To write 10 more than a number, we use the mathematical operation of addition and the notation 10 + Number = N+10.

To write 10 more than a number, we need to use the mathematical operation of addition. Addition is the process of combining two or more numbers to find the total or sum.

In this case, we are given the number 5 and we are asked to find the number that is 3 more than it. To do this, we can use the mathematical notation: 10 + Number = N+10.

This notation means that we are adding 10 to a number, which results in N+10. The "+" symbol is the addition operator and it is used to indicate that we are performing an addition operation. The "=" symbol is used to indicate that the result of the addition is N+10.

Another way to write 10 more than a number is to use the phrase "10 plus a number". This phrase indicates that we are adding 10 to a number to get N+10.

Therefore, In short, to write 10 more than a number, we use the mathematical operation of addition and the notation 10 + Number = N+10. This means that we are adding 10 to a number, resulting in N+10. It can also be written as "10 plus N", indicating the same operation.

If x/y + y/x = -1, the value of \(x^3-y^3\) is \((x - y)(y^2).\)

To find the value of x^3 - y^3, we can use the identity for the difference of cubes, which states that:

\(a^3 - b^3 = (a - b)(a^2 + ab + b^2).\)

In this case, we have:

\(x^3 - y^3 = (x - y)(x^2 + xy + y^2).\)

To find the value of x^3 - y^3, we need to determine the values of x and y. Given that x/y + y/x = -1, we can rewrite this equation as:

\((x^2 + y^2) / (xy) = -1.\)

Multiplying both sides by xy, we get:

\(x^2 + y^2 = -xy.\)

Substituting this expression into the equation for x^3 - y^3, we have:

\(x^3 - y^3 = (x - y)(x^2 + xy + y^2)\\= (x - y)(-xy + xy + y^2) [Using x^2 + y^2 = -xy]\\= (x - y)(y^2).\)

if x/y + y/x = -1, then the value of x³ - y³ is 0.

Prove this using the following steps:

Add 1 to both sides of the equation x/y + y/x = -1:

x/y + y/x + 1 = -1 + 1

(x² + y²) / xy = 0

Multiply both sides of the equation by xy:

x² + y² = 0

Cube both sides of the equation x² + y² = 0:

(x² + y²)³ = 03

x³ + 3x2y + 3xy² + y³ = 0

Subtract 3x2y + 3xy² from both sides of the equation x³ + 3x2y + 3xy² + y3 = 0:

x3 - y3 = -3x2y - 3xy²

Factor out -3xy from the right side of the equation:

x³ - y³ = -3xy(x + y)

Since x/y + y/x = -1, x + y = 0. Substitute this into the equation x³ - y³ = -3xy(x + y):

x³ - y³ = -3xy(0)

x³ - y³ = 0

To find (the derivative of \( y \) with respect to \( x \)) from the given function \( y = \ln(x^2) + \ln(x+3) - \ln(2x+1) \), we can apply the rules of logarithmic differentiation.

First, we can rewrite the function using logarithmic properties:

\(\( y = \ln(x^2) + \ln(x+3) - \ln(2x+1) = \ln(x^2(x+3)) - \ln(2x+1) \).\)

Now, using the rules of logarithmic differentiation, we can differentiate \( y \) with respect to \( x \) as follows:

\( \frac{dy}{dx} = \frac{1}{x^2(x+3)} \cdot (2x(x+3)) - \frac{1}{2x+1} \).

Simplifying further:

\(\( \frac{dy}{dx} = \frac{2x(x+3)}{x^2(x+3)} - \frac{1}{2x+1} \).\( \frac{dy}{dx} = \frac{2x^2 + 6x}{x^2(x+3)} - \frac{1}{2x+1} \).Thus, \( \frac{dy}{dx} = \frac{2x^2 + 6x}{x^2(x+3)} - \frac{1}{2x+1} \) is the derivative of \( y \) with respect to \( x \)\) for the given function.

Step-by-step explanation:

The opposite sides of a parallelogram are equal , so

CD = AB , that is

7x - 54 = 5x - 2 ( subtract 5x from both sides )

2x - 54 = - 2 ( add 54 to both sides )

2x = 52 ( divide both sides by 2 )

x = 26

Then

CD = 7x - 54 = 7(26) - 54 = 182 - 54 = 128 → B

(16)

Consecutive angles are supplementary, sum to 180° , then

6y + 19 + 2y + 9 = 180

8y + 28 = 180 ( subtract 28 from both sides )

8y = 152 ( divide both sides by 8 )

y = 19

Then

∠ B = 6y + 19 = 6(19) + 19 = 114 + 19 = 133°

Opposite angles are congruent , so

∠ D = ∠ B = 133° → C
