For what value of k does the pair of equations 3x y − 8 and 6x KY 16 0 have infinitely many solutions?.

Answers

Answer 1

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.

How do you describe the nature of the roots of a quadratic equation if b2 4ac 0?.

Answers

If the discriminant b² - 4ac = 0 for a quadratic equation ax² + bx + c = 0, it means that the nature of roots of the equation has one real and identical (repeated) root.

When the discriminant is equal to zero, the square root of the discriminant will be zero, and the equation will have one solution for x, regardless of the values of a, b and c.

This can be observed in the quadratic formula, where the square root of the discriminant is used to determine the solutions of x. In this case the equation will be reduced to:

x = -b/2a

It's also possible to observe this by factoring the equation, in this case the equation can be factored as (x - r)^2 = 0, where r is the common root. This means that the graph of the equation will touch the x-axis only once.

In summary, when the discriminant b² - 4ac = 0, the roots of the quadratic equation are real and identical (repeated).

Under what condition do the equations KX Y 2 and 6x 2y 3 have a unique solution?.

Answers

To have a unique solution for the given equations, k should not be equal to 3.

Given equations are:

kx - y = 2

and, 6x - 2y = 3

The second equation can be written as, 3x - y = 3/2

The system of equations kx-y=2 and 3x - y = 3/2 has a unique solution when the coefficients of x and y are not equal, meaning k is not equal to 3.

This is because when the coefficients are not equal, the equations are not dependent on each other and can be solved independently. If the coefficients were equal, then the equations would be parallel and have infinitely many solutions.

Additionally, the specific value of k does not affect the uniqueness of the solution, as long as it is not equal to 3.

In mathematics, the Closure property can be defined as when an arithmetic operation is performed on any two numbers from a set and the result obtained is a number from the set itself, it is considered closed.

Closure property of addition : The closure property of an integer says that when we add two real numbers, the result will always be a real number. The formula for this is written as

a + b = R; where a, b and R are real numbers.

For example, 6 + 13 = 19 ; (1/3) + (5/2) = 17/6

Closure property under multiplication: The product of two real numbers is always a real number, that is, real numbers are closed under multiplication. The formula, ab = R , where a, b, and R are real numbers. For example, 9 × 0 = 0

(3/4) × (-1/4) = -3/16, √3 ×√5 = √15.

The Closure Property of Subtraction states that if any two real numbers a and b are subtracted from each other, the difference or result will also be a real number. For example, 9 - 4 = 5. This property is only applicable to integers and rational numbers.

Three forces with magnitudes of 80 pounds, 95 pounds, and 125 pounds act on an object at angles of 30°, 45°, and 120°, respectively, with the x-axis. Find the direction and magnitude of the resultant of these forces. (Round your answers to one decimal place.)

Answers

To find the direction and magnitude of the resultant of these three forces, we can use the law of cosines and the law of sines.

First, we need to resolve each force into its x and y components using trigonometry.

F1x = 80 * cos(30) = 69.28

F1y = 80 * sin(30) = 40

F2x = 95 * cos(45) = 67.08

F2y = 95 * sin(45) = 67.08

F3x = 125 * cos(120) = -62.5

F3y = 125 * sin(120) = -106.6

Then we can find the x and y components of the resultant force by adding the x and y components of each force respectively.

Rx = F1x + F2x + F3x = 69.28 + 67.08 - 62.5 = 74.86

Ry = F1y + F2y + F3y = 40 + 67.08 - 106.6 = 0.48

Finally, using these values we can use the law of cosines to find the magnitude of the resultant force:

R = sqrt(Rx^2 + Ry^2) = sqrt(74.86^2 + 0.48^2) = sqrt(5633.79) = 75.24

And we can use the law of sines to find the direction of the resultant force:

theta = atan2(Ry, Rx) = atan2(0.48, 74.86) = 0.01

Therefore, the magnitude of the resultant force is 75.24 pounds and the direction of the resultant force is 0.01 degrees.

How to find the end behavior of a graph

Answers

Answer:

x → ∞, y → ∞x → -∞, y → -∞

Step-by-step explanation:

You want the end behavior of the graphed line.

End behavior

The end behavior of a graphed function is found by looking at the arrows on the ends of the graph. If the arrow points in a direction with positive slope, the sign of the function value (y) will match the sign of the independent variable (x).

If the arrow has negative slope, then the signs of the end behaviors will be opposite.

If the arrow points horizontally or vertically, then the end behavior will be an asymptote. The function value will approach the value of a horizontal asymptote. The function value will tend to infinity (up: +∞; down: -∞) as the independent variable approaches the location of the vertical asymptote.

Application

Here, the line has positive slope everywhere, so the sign of y will match the sign of x as both go to ±∞.

x → ∞, y → ∞x → -∞, y → -∞

__

Additional comment

Slope is positive if the sign of the "rise" matches the sign of the "run". A line that goes down to the left has positive slope, just as does a line that goes up to the right. (Right and up are positive directions.)

if tan 0 =-3/4 and 0 is in quadrant IV, what is cos 20 & tan 20

Answers

Using Trigonometric ratios, Tan(20 ) = -24/7 and cos(20) = 7/25

The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths. They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others.

It can be simpler to use a calculator when necessary. (See under)

The reference angle will be less than 45° since the magnitude of the tangent is less than 1. If the angle is less than 90 degrees when doubled, it will remain in the fourth quadrant, where the tangent is negative and the cosine is positive.

Additionally, you can use the identities.

cos(2) is equal to (1 - tan()2)/(1 + tan()2).

cos(2θ) = (1 -(-3/4)²)/(1 +(-3/4)²) = ((16-9)/16)/((16+9)/16)

cos(2θ) = 7/25

Tan(2)=2tan()/(1 -tan(2)2) = 2(-3/4)/((16-9/16) = (-6/4)(16/7)

At x = - 2, g(x) = (-2)² - 2 = 4 - 2 = 2

At x = - 1, g(x) = (-1)² -2 = 1 -2 = -1

At x = 7, g(x) = (7)² -2 = 49 - 2 = 47

Samantha and Phil share some money in the ratio 3:5.
Phil receives £235.
Calculate how much money was shared.
Please help

Answers

If Phil received £235 in the ratio 3:5, we can use this information to find out how much money was shared in total.

We know that the ratio of Samantha's share to Phil's share is 3:5.

This means that for every 3 parts of the total money that Samantha gets, Phil gets 5 parts.

We can use this information to set up a proportion:

(Samantha's share) / (Phil's share) = (3) / (5)

We know that Phil's share is £235, so we can substitute that into the proportion:

(Samantha's share) / (235) = (3) / (5)

To find the total amount of money shared, we can cross-multiply and divide:

Samantha's share = (3/5) * 235

Samantha's share = 141

To find the total amount of money shared, we can add the amount Samantha received to the amount Phil received:

141 + 235 = £376

Therefore, £376 was shared in total.

A polynomial function of least degree with a leading coefficient of 1 and zeroes at -2, 3, 6 is given by:  "f(x) = (x + 2)(x - 3)(x - 6) = x^3 - x^2 - 9x - 12)".

According to the Factor Theorem, k is a zero of a given polynomial function f (x), if and only if (x - k) is a factor of the given polynomial function f(x).

Since -2,3 and 6 are zeros to be given of f (x), so

you need to put -2,3 and 6 in (x - k)

such as

f (x) =  { (x - k) (x - k) (x - k) }

     =  { (x - (-2) (x - 3) (x - 6) }

      =  {(x+2) (x-3)(x-6) }

In Mathematics, an inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).

In order to determine the inverse of any function, you should interchange (swap) both the input value (x-value) and output value (y-value). This ultimately implies that, the inverse relation of any function has its input value (x-value) and output value (y-value) interchanged (swapped) as follows;

The equation that relates the number of coins, y, in Janice's collection x months since she started adding to her collection is y = 26 + 5/3 x In the context of this problem, the y-intercept is the initial number of coins that Janice had in her collection while the slope is the rate at which Janice is adding to her collection which is 5/3.

Part A

The equation for the number of coins, y, in Janice's collection x months since she started adding to her collection is the total amount of coins she has and can be expressed as

y = 26 + 5/3 x

where y is the total number of coins, and x is the number of months.

Part B

The y-intercept of the equation is the point where the line of the equation crosses the y-axis. In this case, the y-intercept is the point (0,26) which means that when x = 0, the number of coins in Janice's collection is 26. This is the initial number of coins that Janice had in her collection before she started adding to it.

The slope of the equation is the rate of change of the dependent variable (y) with respect to the independent variable (x). In this case, the slope of the equation is 5/3, which means that for every 3 months that pass, the number of coins in Janice's collection increases by 5.

Your car's gas mileage is an average of 25 miles per gallon. Let g represent the number of gallons of gas you need to put in your car such that
g (m)=where m is the number of miles you drove. The total cost of filling your car's gas tank is C(x) where C is cost in dollars and x is the number
of gallons purchased.
What does the expression C (g (m)) represent?

Answers

The expression C(g(m)) represents the total cost of filling the car's gas tank based on the number of miles driven.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

It is given that the car's gas mileage is 25 miles per gallon, then the number of gallons of gas needed to fill the car's tank can be found by dividing the number of miles driven by the gas mileage.

The expression for this is g(m) = m / 25 where m is the number of miles driven.

The total cost of filling the car's gas tank is represented by the expression C(x) where C is the cost in dollars and x is the number of gallons purchased.

So when g(m) is substituted into C(x), C(g(m)) is obtained which represents the total cost of filling the car's gas tank based on the number of miles driven.

Therefore, this expression is the cost of filling the gas tank given the number of miles driven.
