Let a function
of 2 variables be defined by h(x, y) = x² + 3xy-(y-x), what is the value of h(5,4)

The next year's population to the nearest individual will be 140,014. The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

There are four fundamental mathematical operations for all real numbers in mathematics, and they are as follows:

1. Obtaining the sum of the numbers through addition ('+').

2. Subtraction using the sign "-" where the difference between the numbers is produced.

3. Multiplication ('×'), which results in the numbers' product.

4. The division ('÷') operation where the quotient of the numbers is determined.

According to the question, the population of a city increases by 2.2% per year and this year's population is 137,000.

Let the population of next year be 'x'

Therefore, we get the following

⇒137,000 + 137,000(2.2%) = x

⇒137,000 + 3014 = x

⇒140,014 = x

Hence, the next year's population to the nearest individual will be 140,014.

Since 3 doughnuts is more expensive than and closer to pricing at 2, Sally can only eat 2 doughnuts.

In economics, marginal utility refers to the addition of pleasure or benefit utility a buyer gets by purchasing an extra unit of a good or service. When marginal utility is greater than or equal to price, total utility is maximized. Minimum Utility MU It speaks about increased utility as a result of consuming an extra unit of a commodity.

The change in overall utility is known as marginal utility.

When she accepts two donuts, her marginal utility is three (8–5=3).

Her marginal utility for eating three donuts is 1 (9 – 8).

Answer: Dilation by 1/4 and translation

Step-by-step explanation:

Answer:

a) In order to write the ratio h:k in its simplest form, we need to find the greatest common divisor (GCD) of h and k and divide both h and k by that value.

The GCD of 2 and 6 is 2.

So the simplified ratio h:k is 2/2:6/2 = 1:3

b) In order to write the ratio k:l in its simplest form, we need to find the greatest common divisor (GCD) of k and l and divide both k and l by that value.

The GCD of 6 and 9 is 3.

So the simplified ratio k:l is 6/3:9/3 = 2:3

Answer:

x (the number) = 19

Step-by-step explanation:

We can translate this into a linear equation. We will use x as our variable (a number). We have:

4x + 21 = 6x - 17

We will add 17 to both sides, and subtract 4x from both sides, giving us:

38 = 2x

Then dividing both sides by 2 gives us:

x = 19

So, x (the number) = 19.

Answer:

a) 4 cosx^4 - cos²2x=0

We can start by splitting the equation into two parts:

4 cosx^4 = cos²2x

cosx^4 = (1/4)cos²2x

From here, we can use the identity:

cos²2x = (cos 2x)² = (2cos²x -1)²

So, we have:

cosx^4 = (1/4)(2cos²x -1)²

Now we can square root both sides:

cosx^2 = (1/2) (2cos²x -1)

Now we square both sides again:

cos²x = (1/4) (2cos²x -1)

We can now subtract (1/4) from both sides and add cos²x to both sides:

(3/4)cos²x = (1/4)

We can now divide both sides by (3/4) to find the value of cosx:

cosx = sqrt(1/3)

So the solutions of the equation are x = (2n+1)π/3, where n is an integer.

b) sec x tan x =sqrt(2)

We know that sec x = 1/cosx and tan x = sinx/cosx.

So we can substitute these values into the equation:

1/cosx * sinx/cosx = sqrt(2)

This simplifies to:

sinx = sqrt(2)cosx

We can now divide both sides by cosx:

tan x = sqrt(2)

So the solutions of the equation are x = pi/4 + nπ, where n is an integer.

Note that the solutions are restricted to the domain where cos(x) is not equal to 0.

It is important to note that this solution is only a small part of the full solution set and that there might be more solutions in specific intervals.

A four-regular graph is a  quartic graph.

A quartic graph is an example of a polynomial function with a degree of four. The formula denotes a quartic function's equation: f(x) = ax4 + bx3 + cx2 + dx + e, where a, b, c, d, and e are constants. A quartic function's graph is a straight line with up to four turning points or extrema. The roots of the polynomial are also referred to as the graph's x-intercepts or the answers to the equation f(x) = 0.

The values of the constants a, b, c, d, and e, as well as whether an is positive or negative, determine the shape of the quartic graph. The graph starts out with an upward slope if it is positive and a downward slope if an is negative. Factorization, the square-root approach, or numerical techniques like the bisection method or the Newton-Raphson method can all be used to solve quartic equations.

The hexagon's side length is 4.5 inches whereas the equilateral triangle's side length is 9.

While an exterior angles are equivalent to the sum of the twin interior angles that become not directly adjacent to it, the inside angles necessarily add up to 180°. By lowering the inclination of the target vertex from 180°, one may also get a triangle's exterior angle.

The equilateral triangle's side length is 9 inches.

The hexagon's sides measure 4.5 inches long.

The equilateral triangle's side length is equal to 1.4x plus 2.

Perimeter = 3(1.4x + 2) = 4.2x + 6 as a result.

The hexagon's side length is equal to 0.5x plus 2.

The perimeter is 6(0.5x + 2) = 3x + 12 as a result.

We use the parallelogram-shaped sponge to create the T-shirt design. The area of the design is 66 square inches. 22 times we will use the sponge to create the design.

Parallelogram:

The term "parallelogram" comes from the Greek word "parallelogram on" which means "surrounded by parallel lines". A parallelogram is a quadrilateral bounded by parallel lines. A shape with opposite sides parallel and equal. Parallelograms fall into three main types: squares, rectangles, and rhombuses, each with its own characteristics.

According to the Question:

Area of the parallelogram-shaped sponge = base × height

                                                                        = 3 inches × 1 inch

                                                                        = 3 square inches

And,

Area of design = 66 square inches

Now,

Number of times to use the sponge to create the design

= Area of design ÷ Area of parallelogram-shaped sponge

= 66 square inches ÷ 3 square inches

= 22 Times

An angle is a shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. Dihedral angles are these.

An angle is a shape created by two rays or lines that meet at the same terminal. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

In geometry, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an item or a form into two equal halves. An angle bisector is a ray that divides an angle into two identical segments of the same length.

An expression using subtraction to find the distance between the two divers is |B - A| or |A - B| or B - A as B > A and the distance using additive inverses is 4 unit.

The number line displays the separation in meters between two divers A and B and the shipwreck at position X:

A = -2.5

X = 0

B = 1.5

We have to write an expression using subtraction to find the distance between the two divers and the distance using additive inverses.

Distance between the two divers = |B - A| or |A - B| or B - A as B > A

Distance between the two divers = |1.5 - (-2.5)| or |-2.5 - 1.5| or  1.5 - (-2.5)
