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

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.

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 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 sine and cosine of the angle of point P are sin θ = 143/145 and cos θ = -24/145 respectively. Option b. is the answer

Given the coordinate of the point as P (-24/145, 143/145)

This implies x = -24/145 and y =  143/145

To determine the sine and cosine of the angle of point P, we can make a sketch using this information (see attached image).

opposite = 143/145, adjacent = -24/145

hypotenuse = √[(-24/145)² + (143/145)²] = √1 = 1

Using trigometric ratios:

sin θ =   (143/145) / 1 = 143/145    [sin θ = opposite/ hypotenuse]

cos θ =  (-24/145) / 1 = -24/145    [cos θ = adjacent/ hypotenuse]

Answer: 12 minutes

Let us suppose the number of minutes per month is 720. ( i have assumed this data from myself, you use any data you want, remember the procedure)

Now, Mark and his brother share the minutes every month equally.

So, clearly, Mark and his brother would get 360 minutes each every month.

Now, Mark has 360 minutes each month

therefore, Mark has 360/30 minutes per day

= 12 minutes each day.

About 24 ,758 years have passed since the cave drawings were created.

If one's age is x now, one's age will be nx in the future. Age n years from now equals x + n if the age at currently is x. Age n years ago equals x - n if the current age is x. The ages will be ax and bx in the ratio a: b.

The time since birth, which is typically expressed as an exact number of years or a finished number of years, is known as a person's chronological age.

A is the current sum.

A0 is the original sum.

A0 = A0 A0 = A0 0.05 e-0.000121t

A / A0 = e-0.000121t

Exponents are frequently referred to as strengths or indices. In plain English, a power expression is one that depicts the same number being multiplied repeatedly, whereas an exponent is a quantity that depicts the powers to which the value is increased.

A = current amount

A₀ = original amount

A = A₀ [tex]e^{-0.000121t}[/tex]

A / A₀ = [tex]e^{-0.000121t}[/tex]

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
