The equations whose graphs encompass a region are thus provided. when the region's area is 301.5
Define area.The region that an object's shape defines as its area. The area of a figure or any other two-dimensional geometric shape in a plane is how much space it occupies. The simplest technique is to multiply the room's length and width. The floor surface area for a rectangular room is equal to the length times the width. The formula for this is area = length x width (A = lw).
Given
g(x) = x²
x = 0
x = 3
We must determine the area using the functions f(x) and g(x), which are provided.
ₐ∫ᵇ (f(x) + g(x)) dx
₀∫³ (x² + 15(x + 5)) dx
₀∫³ (x²dx + ₀∫³15(x + 5)) dx
(x³/3) + 15x²/2 + 75x
₀[x³/3]³ + ₀[15x²/2 + 75x]³
[(3 - 0)³/3] + [15(3 - 0)²/2 + 75(3 - 0)]
27/3 + 15(9/2) + 75(3)

y=-2x coordinate plane
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.

Consider the hyperbolic function (y + 2)(x − 4) = 3.
2.1 Write down the domain and range of the function.
write
equation parallel
through (4,9) (-3,6) and
passes (14,8)
The equation of the line is 3x - 7y + 51 = 0.
What are Parallel Lines ?
Coplanar, parallel lines that don't cross at any point are called parallel lines. Planes in the same three-dimensional space that never cross each other are said to be parallel.
Since the required line is parallel to the line that passes through (4,9) and (-3,6).
So, The slope will be equal to :
m = (y^2 - y^1) / (x^2 - x^1)
here, x^1 = 4, y^1 = 9, x^2 = -3 and y^2 = 6
∴ m = (6 - 9) / (-3 - 4)
= -3/-7
= 3/7.
We know that, The equation of a line is (y - y^1) = m (x - x^1)
∴ The equation of the required line will be :
y - 9 = 3/7 ( x - 4)
7y - 63 = 3x - 12
3x - 7y + 51 = 0.

What do histograms mean?To visually depict data, a histogram is utilized. The histogram is made up of rectangles with widths equal to the class interval and areas equal to the frequency of the data.
The intervals' widths must match. This implies that there must be an equal distance between the lower bound and the higher bound. Additionally, the lower bound of the subsequent interval's interval must match both its upper and lower bounds.
This means that the intervals must be overlapping. Of all the options, it is 0 – 30, 30 – 55, 55 – 80, 80 – 105, and 105 – 130 that satisfy both conditions.

A metallurgist has one alloy containing 28% aluminum and another containing 59% aluminum. How many pounds of each alloy must he use to make 42 pounds of a third alloy containing 30%
The number of pounds from one alloy is 2.71.
The number of pounds from another alloy is 39.29.
What is an equation?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.

Thomas earned $46.50 in 4 hours at his job today. How much can he earn tomorrow if he works 10 hours at the same hourly rate? Do NOT include a dollar sign in your answer.
Answer:
116.25 0r 116.30
Step-by-step explanation:
To find the hourly rate, divide the pay by the number of hours
So 46.50/4 = 11.625
You should round that to 11.63
Then, multiply the hourly rate by the number of hours worked the next day.
So 11.63 x 10 = 116.30
a racing venue wants to make the charity race 5% longer. If the race was 25km, what is the new race length
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.
How to calculate the value of x?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:
Secant: 27 + 2x + 2 = 2x + 29.External segment: 2x + 2.Tangent: 3x - 9.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.
Which is a quadratic equation with the coefficients given as follows:
a = 5, b = -116, c = 23.

Given quadrilateral ABCD with A(-4,-2), B(-3,2), C(2,4) and D(4,-3). Find the area in square units.
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
What is a quadrilateral?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 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
How to determine the sine and cosine of the angle of point P?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]
