What is the constant proportional of 1.5 and 3.9

The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value "5" is the Y Coordinate.

The area of the rectangle =  9x² +18x−16

What is the area of the rectangle?

The area of a rectangle is calculated by multiplying the height by the width. If the height of the rectangle is represented by h and the width is represented by w, then the area is given by:

A = h * w

In this case, the height of the rectangle is given as 3x - 2 yards, and the width is given as 3x + 8 yards. So, substituting these values into the formula:

A = (3x - 2) * (3x + 8)

A = (3x - 2)(3x + 8)

A = 9x² +18x−16

Inga is solving 2x² + 12x – 3 = 0 therefore the steps which she could use to solve the quadratic equation include the following below:

This is referred to as an algebraic equation of the second degree in x and its standard form is ax² + bx + c = 0

Solution to the quadratic equation

2x² + 12x - 3 = 0

2x² + 12x = 3

Divide by 2

x² + 6x = ³/₂

(x + 3)² = ³/₂ + 3²

x² + 6x + 9 = 9 + ³/₂

2(x² + 6x + 9) = 18 + 3

Thus, the steps that she could use to solve the quadratic equation is determined as option 1, 3 and 4.

Mr. Black was driving at 60 mph to his friend's house.

Let's call Mr. Black's speed to his friend's house "x".

The trip back took x - 20 mph, since he was driving 20 mph slower.

The trip back took 1 hour longer, so it took 2 + 1 = 3 hours.

Using the formula for distance = rate x time, we can set up the equation:

x * 2 = (x - 20) * 3

Expanding and simplifying, we get:

2x = 3x - 60

Subtracting 2x from both sides:

0 = x - 60

Adding 60 to both sides:

The exponential growth function 0f3=61025/ 04-0295254 0f=423 0fx)=(-1257 is not a valid equation.

Step-by-step explanation:

A function: 9x² - y² = 1.

Differentiating with respect to x is 18x - 2y dy/dx = 0.

The correct option is B.

Mathematicians use a procedure called differentiation to determine a function's instantaneous rate of change based on one of its variables.

Given:

A function: 9x² - y² = 1.

Differentiating with respect to x,

we get,

d/dx(9x² - y²) = d/dx(1)

18x - 2y dy/dx = 0

The length of NP is 6.28 cm

A triangle is a two-dimensional geometric shape with three sides and three angles. It is one of the basic shapes in geometry and has many different properties that can be studied. Triangles can be classified into several different types based on the length of their sides and the size of their angles.

The most basic type of triangle is an equilateral triangle, which has three sides of equal length and three equal angles. Another common type of triangle is the right triangle, which has one right angle (90 degrees) and two other angles that add up to 90 degrees. Scalene triangles have no sides or angles of equal length, while isosceles triangles have at least two sides of equal length.

Triangles have many interesting and useful properties that can be used in geometry and other areas of mathematics. For example, the Pythagorean Theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side. This theorem can be used to find the length of a missing side in a right triangle.

To find angle P and angle M, we can use the fact that the sum of the angles in a triangle is 180 degrees.

angle P + angle M + 46 = 180

angle P + angle M = 134

Next, we can use the law of cosines to find angle P. Let's call the length of NP "x".

cos(angle P) = (MN² + MP² - x²) / (2 × MN × MP)

We can use the formula for cosine to solve for angle P:

angle P = arccos((MN² + MP² - x²) / (2 × MN × MP))

Substituting in the values for MN and MP:

angle P = arccos((4² + 7² - x²) / (2 × 4 × 7))

Next, we can use the Pythagorean theorem to find x:

x^2 = MN^2 + MP^2 - 2 * MN * MP * cos(angle P)

x^2 = 4^2 + 7^2 - 2 * 4 * 7 * cos(angle P)

x² = 49 - 56 × cos(angle P)

Substituting in the value we found for angle P:

x² = 49 - 56 × cos(arccos((4² + 7² - x²) / (2 × 4 × 7)))

Solving for x, we get:

x = sqrt(49 - 56 × cos(arccos((4² + 7² - x²) / (2 × 4 × 7))))

x = sqrt(49 - 56 × cos(arccos(33 / 28)))

x = √(49 - 56 × (33 / 28) / √(33² + 28²))

x = √(49 - 56 × 33 / 28 / √(33^2 + 28^2))

Finally, we can use the value we found for x to find angle M:

angle M = 134 - angle P

angle M = 134 - arccos((4² + 7² - x²) / (2 × 4 × 7))

So the final answers are:

angle P = arccos((4² + 7² - x²) / (2 × 4 × 7)) = 68.93 degrees

angle M = 134 - angle P = 65.07 degrees

length of NP = x = sqrt(49 - 56 × 33 / 28 / √(33² + 28²)) = 6.28 cm

On solving the provided question, we can say that the inequality formed is 1 ≥ 2(3)-5 => 1 ≥ 1

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

The ordered pair is (3, 1)

Substitute (x, y)=(3, 1) in the given inequality, we get

Jada stacked 23 boxes inside the container.

Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges.

Given that, Jada put some cube-shaped boxes having lengths 20 in, in a cubed container has side lengths of 60 inches in.

After, Jada stacks the boxes inside the container, there are still 32,000 in³ of empty space remaining in the container.

We need to find the number of the boxes in the container.

Volume of cube = (side)³

Volume of container = 60³ = 216000 in³

Volume of the container covered by stacking the boxes =

216000 - 32000

= 184000 in³

Volume of each box = 20³

= 8000 in³

Number of boxes in the container = volume of the container covered by stacking / volume of each box

Number of boxes = 184000 / 8000

= 23

Hence, Jada stacked 23 boxes inside the container.

The solution of the linear equations −7x + 3y = −48 and 3x + 5y = −36 will be (3, −9)

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equations are given below.

−7x + 3y = −48           ...1

3x + 5y = −36            ...2

Multiply equation 1 by 5 and equation 2 by - 3, then we have

−35x + 15y = −240

−9x − 15y = 108

Add both equations, then we have

−44x = −132

x = 132 / 44

x = 3

Then the value of 'y' is given as,

3(3) + 5y = −36

9 + 5y = −36

5y = −45

y = −9
