For what value of k does the pair of equations 3x y − 8 and 6x KY 16 0 have infinitely many solutions?.
The value of k for which the pair of equations 3xy - 8 = 0 and 6xky - 16 = 0 have infinitely many solutions is 4.
To solve this question, we need to find the value of k for which the two equations are equivalent. Equivalence means that the coefficients of x and y are the same and the constant terms are the same.
From the given equations, we can see that the coefficients of x and y are the same in both equations, which is 6x. The constant terms, however, are different. The first equation has a constant term of -8, while the second equation has a constant term of -16.
To make the equations equivalent, we need to make the constant terms the same. We can do this by dividing the second equation by 2. This gives us 6 ky - 8 = 0. We can see that the constant term is now the same as the first equation. Therefore, the value of k that makes the equations equivalent is k = 4.

the measurements, to the nearest centimeter, of a box are given as 10cm x 7cm x 4cm. calculate the upper and lower bounds for the volume of the box.
In summary, the upper and lower bounds for the volume of the box are:
Upper bound: 382.125cm³
Lower bound: 238.375cm³
The volume of the box is calculated by multiplying the length, width, and height together. In this case, the measurements of the box are given as 10cm x 7cm x 4cm, so the volume of the box is:
volume = 10cm x 7cm x 4cm = 280cm³
However, since the measurements are given to the nearest centimeter, there is a slight degree of uncertainty in the exact measurements of the box. To calculate the upper and lower bounds for the volume of the box, we need to consider the possible variations in the measurements.
The upper bound for the volume would be calculated by taking the highest possible measurements for each dimension. So, if the length could be as much as 10.5cm, the width could be as much as 7.5cm and the height could be as much as 4.5cm. Then the upper bound for the volume would be:
Upper bound = 10.5cm x 7.5cm x 4.5cm = 382.125cm³
The lower bound for the volume would be calculated by taking the lowest possible measurements for each dimension. So, if the length could be as little as 9.5cm, the width could be as little as 6.5cm and the height could be as little as 3.5cm. Then the lower bound for the volume would be:
Lower bound = 9.5cm x 6.5cm x 3.5cm = 238.375cm³
In summary, the upper and lower bounds for the volume of the box are:
Upper bound: 382.125cm³

If y =sin x sec (90-x) , what is value of dy/dx of the previous ?
Answer:
We can use the chain rule to find the derivative of y with respect to x.
The chain rule states that if y = f(u) and u = g(x), then dy/dx = dy/du * du/dx
y =sin x sec (90-x)
dy/dx = cos x sec (90-x) * d/dx(sec (90-x)) - sin x tan (90-x) sec (90-x) * d/dx(90-x)
let us calculate the second derivative
du/dx = -cos(90-x)
d²y/dx² = -sin x sec (90-x) * cos (90-x) - cos x tan (90-x) sec (90-x) * cos (90-x) - cos x sec (90-x) * (-sin (90-x))
= -sin x sec (90-x) * cos (90-x) - cos x tan (90-x) sec (90-x) * cos (90-x) + cos x sec (90-x) * sin (90-x)
= -sin x sec (90-x) * cos (90-x) + cos x tan (90-x) sec (90-x) * sin (90-x)
= -(sin^2 x + cos^2 x) sec (90-x) tan (90-x)
= -sec^2 (90-x) tan (90-x)
So, the value of the second derivative of y with respect to x is -sec^2 (90-x) tan (90-x)

22. Four friends, Lerato, Jarrod, Ian and Tandeka, play a computer game in which they race a car around a circuit. Lerato takes 2 minutes, Jarrod takes 3 minutes, Ian takes 4 minutes and Tandeka takes 5 minutes to complete one circuit of the game. They play for a total of 12 minutes. a) If they play continuously and at the same rates, which one of the players will be in the middle of a circuit as the time runs out? b) After how many minutes did this player begin the last circuit? c) How many more games did Lerato play than Tandeka?
Answer:
a) Tandeka will be in the middle of a circuit as the time runs out.
b) Tandeka began the last circuit after 7 minutes.
c) Lerato played 2 more games than Tandeka.
Explanation:
a) To determine which player will be in the middle of a circuit when the 12 minutes are up, we need to figure out which player completes the most circuits in 12 minutes. We can use the formula: time available / time per circuit = number of circuits completed. In this case: 12 minutes / 2 minutes per circuit = 6 circuits for Lerato, 12 minutes / 3 minutes per circuit = 4 circuits for Jarrod, 12 minutes / 4 minutes per circuit = 3 circuits for Ian, 12 minutes / 5 minutes per circuit = 2.4 circuits for Tandeka. Tandeka completes 2 full circuits, and starts the third one, hence she will be in the middle of a circuit when the time runs out.
b) To determine when Tandeka began the last circuit, we need to figure out how many minutes were left when she completed the second circuit. We know that Tandeka completes 2 full circuits in 10 minutes (2 x 5 minutes). So, the last circuit starts after 12 minutes - 10 minutes = 2 minutes
c) To determine how many more games Lerato played than Tandeka, we can subtract the number of games Tandeka played from the number of games Lerato played: 6 games - 4 games = 2 games.

The slope conveys how quickly the dependent variable shifts in response to changes in the independent variable. Mathematicians and economists frequently use the Greek capital D or D to denote change. The change in the horizontal axis, x, is contrasted with the change in the vertical axis, y.
Negative values are below the origin on the x-axis and to the left of the origin on the y-axis. If the y-coordinate is negative, go downhill; if the x-value is negative, start at the origin and travel to the left.
Line graphs, often referred to as XY graphs, are used to graphically display data (the results of an experiment) to show how multiple aspects, such as time and the severity of the disease, are related.

How many images will form when two mirrors are placed at 120 degree and 30 degree object is placed symmetrically with respect to both the mirrors?.
The number of images formed by using the angle 120° is 3 or 30° is 11.
Angle in math is defined as the image formed when two rays are joined together at a common point and the common point here is called node or vertex and the two rays are called arms of the angle.
Here we have given that 120 degree and 30 degree object is placed symmetrically with respect to both the mirrors.
As we all know that the formula number of images formed between two mirrors kept at some angles is written as,
=> n = (360 / θ) - 1
Here we have n is the number of images and θ is the angle between the mirrors.
The value of θ is 120 or 30.
If the angle is 120, then the number of image is calculated as,
=> n = (360 / 120) - 1
=> n = 3 - 1 = 2
Where as the angle is 30, then the number of image is calculated as,
=> n = (360 / 30) - 1
=> n = 12 - 1 = 11

How do special right triangles theorems 45 45 90 and 30 60 90 differ from each other?.
The 45-45-90 triangle has two congruent sides and one right angle, with each angle measuring 45°. The sides are perpendicular to each other and the length of the hypotenuse is equal to the square root of 2 times the length of a leg.
The 30-60-90 triangle has one right angle and two sides that are proportional. The shortest side is half the length of the hypotenuse and the middle side is equal to the shortest side times the square root of 3. The two acute angles in the triangle measure 30° and 60°, respectively.
In conclusion, both 45-45-90 and 30-60-90 triangles are special right triangles with distinct relationships between their sides and angles.
A triangle is a polygon with three edges and 3 vertices. The terminology for categorizing triangles is more than two thousand years vintage, having been defined on the first actual page of Euclid's elements.
In Euclidean geometry, any three factors, while non-collinear, decide a completely unique triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean space). In different words, there's best one plane that consists of that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is the best one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is not real. this text is ready triangles in Euclidean geometry, and in particular, the Euclidean plane, except wherein otherwise stated.
