True, Tissue culturing is a form of vegetative reproduction that requires only a very small amount of tissue.

Tissue culture is the growth of tissues and/or cells that have been isolated and maintained in artificial conditions outside the living organism from which they were derived. Tissue culturing has several applications in agriculture, horticulture, and medicine. It involves the growth of cells or tissues in an artificial environment (in vitro) to create new organisms or clones of the parent organism.This form of reproduction is an asexual type of reproduction, in which a new plant is generated from a tiny amount of parent plant tissue, such as a leaf or stem cutting. This approach is known as micropropagation, and it enables horticulturists to create new cultivars and mass-produce plant varieties with desired characteristics.

Step-by-step explanation:

The equation for the line tangent to the circle \(\(x^2 + y^2 = 169\)\) at the point \(\((-5, 12)\)\) is \(\(x + 5y = 13\)\).

To find the equation of the tangent line to the circle at a given point, we need to determine the slope of the tangent line and its point of tangency. The slope of the tangent line is equal to the negative reciprocal of the derivative of the circle's equation with respect to x.

Differentiating the equation \(\(x^2 + y^2 = 169\)\) with respect to x, we get \(\(2x + 2y \frac{{dy}}{{dx}} = 0\)\). Rearranging this equation, we find \(\(\frac{{dy}}{{dx}} = -\frac{{x}}{{y}}\)\).

Substituting the coordinates of the given point (-5, 12) into the derivative, we have \(\(\frac{{dy}}{{dx}} = -\frac{{-5}}{{12}} = \frac{{5}}{{12}}\)\).

Since the tangent line has the same slope as the derivative at the point of tangency, the slope of the tangent line is \(\(\frac{{5}}{{12}}\)\).

Using the point-slope form of a line, \(\(y - y_1 = m(x - x_1)\)\), where \(\((x_1, y_1)\)\) is the given point, we substitute \(\((-5, 12)\)\) and the slope \(\(\frac{{5}}{{12}}\)\) to obtain \(\(y - 12 = \frac{{5}}{{12}}(x + 5)\)\).

Simplifying this equation, we get \(\(x + 5y = 13\)\), which is the equation of the tangent line to the circle at the point \(\((-5, 12)\)\).

The likelihood of events A and B overlapping is 25% (or 0.25), assuming both are unrelated. To determine the precise likelihood, extra information is required if they are dependent.

Whether occurrences A and B are independent or dependent determines the likelihood that they will overlap. Let's think about both possibilities:
Events A and B must be independent of one another for their probabilities to be unaffected by one another.
In this scenario, there is a 50% (0.5) chance of event A happening and a 50% (0.5) chance of event B happening.
We add their probabilities together to get the likelihood that the two occurrences will occur simultaneously:

Probability (A and B) = Probability (A) * Probability (B) = 0.25 or 0.5%.Events A and B that are dependent on one another may have different effects on their probabilities.
It is difficult to calculate the exact probability of overlap without additional knowledge about the dependency's nature.

By utilizing the stored procedure, we can easily and efficiently modify the maximum group size of a trip by providing the trip ID and the desired new maximum group size as input parameters.

The stored procedure in T-SQL can be used to change the maximum group size of a trip with a given trip ID. In this case, we would use the stored procedure to change the maximum group size of trip 21 to 15.

To create the stored procedure, we would define a parameter for the trip ID and the new maximum group size. The procedure would then update the corresponding record in the trips table with the new maximum group size based on the provided trip ID.

Here's an example of the T-SQL stored procedure:

  sql

CREATE PROCEDURE ChangeMaxGroupSize

   TripID INT,

   NewMaxGroupSize INT

AS

BEGIN

   UPDATE trips

   SET MaxGroupSize = NewMaxGroupSize

   WHERE TripID = TripID

END

To use this stored procedure to change the maximum group size of trip 21 to 15, we would execute the following command:

sql

EXEC ChangeMaxGroupSize TripID = 21, NewMaxGroupSize = 15

This would update the trips table, specifically the record with TripID 21, setting the MaxGroupSize column to 15. By utilizing the stored procedure, we can easily and efficiently modify the maximum group size of a trip by providing the trip ID and the desired new maximum group size as input parameters.

The largest possible volume of the inscribed right circular cylinder is 810π \(cm^3\).

To find the largest possible volume of a right circular cylinder inscribed in a cone with height 10 cm and base radius 9 cm, follow these steps:

1. Set up the problem: Let h be the height of the cylinder and r be the radius of its base. The cylinder is inscribed in the cone, so their heights and radii are proportional. Therefore, we have the relationship:

  h/10 = r/9

2. Solve for h: Multiply both sides of the equation by 10 to isolate h:

  h = 10r/9

3. Write the volume formula for a cylinder: V = π\(r^2\)h

4. Substitute h from step 2 into the volume formula:

  V = π\(r^2\)(10r/9)

5. Differentiate the volume formula with respect to r to find the critical points:

  dV/dr = d(10π\(r^3\)/9)/dr = 10πr^2

6. Set the derivative equal to zero and solve for r:

  10π\(r^2\) = 0
  r = 0 (This is not a valid solution since the radius must be greater than zero)

7. Since there's no valid critical point, the maximum volume occurs at the endpoints of the interval. In this case, the radius can be between 0 and 9, so we'll test r = 9:

  h = 10(9)/9 = 10

8. Calculate the volume with r = 9 and h = 10:

  V = π(\(9^2\))(10) = 810π \(cm^3\)

The largest possible volume of the inscribed right circular cylinder is 810π\(cm^3\).

Because the value of x is 126° and the value of cos 2x is -0.301, which is fractionally identical to -7/25, the value of cos 2x will be -7/25.

Trigonometry is the study of angles and the angular relationships between planar and three-dimensional shapes. The cosecant, cosine, cotangent, secant, sine, and tangent are among the trigonometric functions (also known as the circle functions) that make up trigonometry. The sine, cosine, and tangent are the three fundamental trigonometric operations. The cotangent, secant, and cosecant functions are derived from these three basic functions. On these functions, all trigonometrical concepts are built.

Here,

x=126°

Cos 126°=-0.588

cos (2*126)=-0.310

a) To find V(0), V(5), V(10), and V(70), we substitute the respective values of t into the given expression for V(t):

V(0) = 40 - 25(0)²/(0 + 3)² = 40

V(5) = 40 - 25(5)²/(5 + 3)² = 40 - 625/64 ≈ 30.86

V(10) = 40 - 25(10)²/(10 + 3)² = 40 - 2500/169 ≈ 24.68

V(70) = 40 - 25(70)²/(70 + 3)² = 40 - 122500/5476 ≈ 17.62

b) To find the maximum value of the inventory over the given interval, we can find the critical points of the function V(t) by taking the derivative and setting it equal to zero:

V'(t) = (dV/dt) = (-50t(t + 6))/((t + 3)³)

Setting V'(t) = 0:

-50t(t + 6) = 0

This equation has two solutions: t = 0 and t = -6. However, since t represents time, we can discard the negative value t = -6.

Therefore, the maximum value of the inventory over the interval occurs at t = 0.

c) To sketch a graph of V, we can plot the values obtained in part (a) and connect them to visualize the shape of the curve.

d) Based on the given function V(t) = 40 - 25t²/(t + 3)², we can see that as t approaches negative infinity or positive infinity, the term -25t²/(t + 3)² approaches zero. This implies that V(t) will approach the constant value of 40. Therefore, there is a value (in this case, 40) below which V(t) will never fall.
