The first Epistle of John was written about AD of between 95 and 110 . So, by this our option should be 97 AD, which is true.

The Fourth of the Catholic Epistles, The First Epistle of John[a] is the first of the Johannine epistles in the New Testament. The authorship of the Johannine writings is disputed among academics. The First Epistle's author is identified as John the Evangelist, who most scholars do not consider to be the same person as John the Apostle. The three Johannine epistles are thought to have been written by the same person by the majority of scholars, however it is unclear if the same person wrote the Gospel of John.

when interpreting a histogram with a normal curve, it is important to look at the shape of the histogram and compare it to the shape of the normal curve. This can help us determine if the data is normally distributed, identify outliers, and determine the goodness of fit of the data to a normal distribution.

Histograms and normal curves are two commonly used graphical representations of data. A histogram is a bar graph that represents the frequency distribution of a set of continuous data. A normal curve, also known as a Gaussian distribution or Bell curve, is a symmetrical and bell-shaped curve that represents the probability density function of a normally distributed set of data.

When a histogram is superimposed with a normal curve, it allows us to visually compare the distribution of the data with a normal distribution. In this article, we will discuss how to interpret a histogram with a normal curve.

The equivalent expression to the given expression ( 5/2) + 2( 2/5) + 7  is given by 11 ( 9 /10) .

Simplify the expression to get the equivalent expression:

( 5/2) + 2( 2/5) + 7

Convert mixed fraction 2( 2/5) into proper fraction we get:

2 ( 2 / 5 ) = ( 5 × 2 + 2 ) / 5

               = 12 / 5

Now, take the least common multiple of denominator we have:

( 5 / 2 ) + ( 12 / 5) + 7 / 1

Least common multiple of 2, 5, 1 is 10

( 5/ 2 ) × ( 5 / 5 ) + ( 12 / 5 )× ( 2/2) + ( 7 / 1) × ( 10 /10)

=( 25 / 10) + ( 24 /10) + ( 70 /10)

= ( 25 + 24 + 70 ) / 10

= 119 / 10

= 11 ( 9 /10)

It is true that if v in r3 and v·v = 0, then v is the zero vector.

If v is a vector in R3 (three-dimensional real space) and v·v = 0, then v is the zero vector.

The dot product of a vector with itself, v·v, is equal to the square of the magnitude of the vector, ||v||^2. If v·v = 0, it follows that ||v||^2 = 0, which means that the magnitude of v is 0. In other words, v has a length of 0.

The only vector in R3 with a length of 0 is the zero vector, which is represented by the vector (0, 0, 0). Thus, if v·v = 0, v must be the zero vector.

The combined cost of c dollars is a xπx² + 2πxhb. The volume of the tank will be V = πx²h. Maximum value of V is when c > 2a(2hb).

a. The cost of the base is given by a xπx², and the cost of the curved surface is given by 2πxhb. The combined cost of the base and curved surface is given by:

c = a xπx² + 2πxhb

b. To find the volume of the tank, we can use the formula for the volume of a cylinder:

V = πx²h

Substituting in the expression for c from part (a), we have:

V = πx²h = πx²(c - 2πxhb) / a

c. To find the maximum value of V, we can differentiate with respect to x and set the derivative equal to 0:

dV/dx = 2πx(c/a - 2hb) = 0

Solving for x, we get:

x = (c / 2a) / (2hb)

Since x is the radius of the tank, it must be positive, so we must have c > 2a(2hb) for the maximum value of V to exist.

We have to find the cost of polishing the floor.

First we will calculate the area of floor of the square hall.

Area of a square is defined as the number of square units needed to fill a square. In general, the area is defined as the region occupied inside the boundary of a flat object or 2d figure. The measurement is done in square units, with the standard unit being square meters ([tex]m^{2}[/tex]).

Per square meter cost of polishing the floor is ₹15,

To find the cost of polishing the floor of the square hall of area 156.25 sq. m, simply multiply 15 by the area of the floor of the square hall.

The vectors v and w must be parallel if the value of an is 3/a2.

The parts of each vector must be proportionate for v to be parallel to w.

v = 3ai + 2j

w = (a^2)i + 6j

Therefore,

3a / a^2 = 2 / 6

3a = (2/6)a^2

a = 3/a^2

The components of each vector must be proportionate in order to make two vectors parallel. In this situation, we wish to make v parallel to w because we have two vectors, v and w. We can use the following equations to express v and w:

v = 3ai + 2j

w = (a^2)i + 6j

We need to determine the ratio between the x-components (3a and (a2)) and the y-components (2 and 6), as we can see that they are not currently proportionate. To do this, we can construct a proportional equation where the ratio is 3a / a2 on one side and 2/6 on the other. This problem can be solved for a by simplifying the equation to 3a = (2/6)a2. This yields a value of 3 / a2, indicating that the value of a must be 3 / a2 for v and w to be parallel.

Each side of the square should be matched with its slope as follows;

In order for a quadrilateral to be a square, the two (2) pairs of its sides must be equal (congruent) and perpendicular to each other. Therefore, we would have to calculate the slope of each side by using this mathematical expression:

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Where:

x and y represents the data points or side lengths of a quadrilateral.

For side WX, the slope is given by:

Slope (m) = (3 - 2)/(5 - (-3))
