Answer: [tex]h(x)=549(0.7)^{x}[/tex]

Step-by-step explanation:

The required equation of the line is given as y = 5x -6.

To determine the equation of a line passing through the point (-4, -11) and perpendicular to the line 4x + 5y = -45.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope of the given line
4x + 5y = -45
y = -4/5 - 45
m = -4/5

The equation of the perpendicular line is given as,
y - y₁ = -1/m (x - x₁)
Substitute the value in the above equation,
y + 11 = -1 / -4/5  (x + 4)
y = 5/4(x + 4) - 11
y = 5x + 5 - 11
y = 5x -6

As a result, the needed equation for the line is y = 5x -6.

The number of pounds from one alloy is 2.71.

The number of pounds from another alloy is 39.29.

An equation is a mathematical statement of two expressions connected by an equal sign.

We have,

x = pounds from one alloy

y = pounds from the second alloy

Two equation.

28% of x + 59% of y = 30% of 42

0.28x + 0.59y = 0.30 x 42 ______(1)

x + y = 42 _____(2)

Now,

x = 42 - y ________ (3)

Putting (3) in (2)

0.28(42 - y) + 0.59y = 0.30 x 42

11.76 - 0.28y + 0.59y = 12.6

11.76 + 0.31y = 12.6

0.31y = 12.6 - 11.76

0.31y = 0.84

y = 2.71

Now,

x = 42 - y

x = 42 - 2.71

x = 39.29

Thus,

The number of pounds of each alloy is 2.71 and 39.29.

Answer:

The Y=-2x coordinate plane is a two-dimensional plane that represents all possible points with coordinates that satisfy the equation Y=-2x. The Y axis is the vertical axis, and the X axis is the horizontal axis. A point on the Y=-2x coordinate plane can be represented by an ordered pair (x, y), where x is the distance of the point from the Y axis, and y is the distance of the point from the X axis. In the Y=-2x coordinate plane, the Y coordinate of a point is always equal to -2 times the X coordinate of that point.

The area of the quadrilateral ABCD, with the vertices coordinates A(-4, -2), B(-3, 2), C(2, 4), and D(4, -3), is 18 square units

A quadrilateral is a four sided polygon, that has a sum of the interior angles of 360°

The area of the quadrilateral can be calculated as comprising of the area of two triangles, with vertices; B(-3, 2), C(2, 4), D(4, -3), and B(-3, 2), C(2, 4), A(-4, -2)

The area of a triangle with known coordinates of the vertices is precented as follows;

Let (x₁, y₁), (x₂, y₂), (x₃, y₃) represent, the vertices of the triangle, we get;

A = 0.5×|x₁·y₂ - x₂·y₁ + x₂·y₃ - x₃·y₂ + x₃·y₁ - x₁·y₃|

Therefore;

The area, A₁ of the triangle ΔBCD with vertices at the coordinates (-3, 2), (2, 4), (4, -3), is found as follows;

A₁ = 0.5 × |(-3)×4 - 2×2 + 2 ×(-3) - 4 × 4 + 4×2 - (-3)×4| = 9

Similarly, the area, A₂, of the triangle, ΔBCA with vertices (-3, 2), (2, 4), (-4, -2), is found as follows;

A₂ = 0.5 × |(-3)×4 - 2×2 + 2 ×(-2) - (-4) × 4 + (-4)×2 - (-3)×(-2)| = 9

The area of the quadrilateral, A = A₁ + A₂, is therefore;

The area of the A = 9 + 9 = 18

The area of the quadrilateral ABCD is 18 square units

Step-by-step explanation:

The probability that, for a sample of 40 college games to be played next week, the mean number of holding penalties will be 2 penalties per game or more is of:

0.9582 = 95.82%.

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The parameters for this distribution are given as follows:

[tex]\mu = 2.3, \sigma = 1.1, n = 40, s = \frac{1.1}{\sqrt{40}} = 0.1739[/tex]

The probability that the mean number of holding penalties will be 2 penalties per game or more is one subtracted by the p-value of Z when X = 2, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (2 - 2.3)/0.1739

Z = -1.73.

Z = -1.73 has a p-value of 0.0418.

Hence:

The value of x in the circle is given as follows:

x = 23.

The value of x in the circle is calculated using the tangent-secant theorem, which states that when a secant and a tangent are drawn to a circle from the same external product, the product of the length of the secant and of it's external segment equals the square length of the tangent segment.

The parameters for this problem are given as follows:

Then, the value of x is obtained applying the product from the tangent-secant theorem as follows:

(2x + 29)(2x + 2) = (3x - 9)²

4x² + 62x + 58 = 9x² - 54x + 81

5x² - 116x + 23 = 0.

The length of the racing venue after the increase of 5 % is 26.25 km

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the increased length of the racing venue be = A

Let the total length of the racing venue be = 25 km

The percentage increase in the length of the racing venue = 5 %

So , the equation will be

Increased length of the racing venue = total length of the racing venue + ( percentage increase in the length of the racing venue x total length )

Substituting the values in the equation , we get

Increased length of the racing venue = 25 + ( 5/100 ) x 25

Increased length of the racing venue = 25 + ( 5/4 )

Increased length of the racing venue = 25 + 1.25

Increased length of the racing venue = 26.25 km

Therefore , the value of A is 26.25 km

Hence ,

The length of the racing venue after the increase of 5 % is 26.25 km

The functions f and h are not the same because they are composed of different operations.

A function is a block of code that performs a specific task. It can accept input in the form of parameters, and may return an output. Functions are an important part of programming, as they allow for the repetition of code without having to write the same lines multiple times. This increases code readability and eliminates the need to debug multiple lines of code. Functions can also be reusable, meaning they can be called and used over and over again with different parameters.

Function f takes the ratio of two terms while function h takes the product of two terms. Additionally, the terms in the two functions are different. Function f takes the sum of x and 5 and the difference of x and 7 while function h takes the sum and the difference of the same two terms. As a result, the functions f and h will generate different outputs for the same input.

Interval notation

The domain is the set of all possible input values (x-values).

The range is the set of all possible output values (y-values).

The graph is a conic section (ellipse) and therefore it is not a function.

The smallest x-value is x = -6 and the greatest x-value is x = 6.

The smallest y-value is y = -3 and the greatest y-value is y = 7.

Therefore, the domain and range in interval notation are:

The graph is a not a function as almost all the inputs (x-values) are related to more than one output (y-value).

From inspection of the graph, the endpoints of the continuous line are:

Both endpoints are closed circles, so the values are included in the domain and range.

The smallest x-value is x = -2 and the greatest x-value is x = 2.  

Therefore, the domain in interval notation is:

The smallest y-value is y = -6 and the greatest y-value is y = 6.  

Therefore, the range in interval notation is:

The graph is a not a function as not all inputs (x-values) are related to one output (y-value).
