The area of the region bounded by the curves is approximately 72.75 square units.
What is parabola?A parabola is the portion of a right circular cone cut by a plane perpendicular to the cone's generator. It is a locus of a point that moves such that the separation between it and a fixed point (focus) or fixed line (directrix) is the same.
To sketch the region bounded by the curves 2x² - y = 20 and x⁴ - y = 4, we can begin by graphing each equation separately.
First, the equation 2x² - y = 20 can be rearranged to solve for y:
y = 2x² - 20
This is a downward-facing parabola that opens towards the vertex at (0, -20).
Next, the equation x⁴ - y = 4 can be rearranged to solve for y:
y = x⁴ - 4
This is an upward-facing parabola that opens towards the vertex at (0, -4).
To find the intersection points of the two curves, we can set the right-hand sides of the equations equal to each other:
2x² - y = 20
x⁴ - y = 4
Substituting y from the second equation into the first equation, we get:
2x² - (x⁴ - 4) = 20
Simplifying and rearranging, we get:
x⁴ - 2x² - 24 = 0
Factoring, we get:
(x² - 4)(x² + 6) = 0
This gives us four solutions:
x = ±2 and x = ±√6
Substituting these values of x into either of the original equations, we can find the corresponding y-values:
When x = 2, y = 4
When x = -2, y = 36
When x = √6, y = 2(6)² - 20 = 32
When x = -√6, y = 2(6)² - 20 = 32
So the intersection points are (2, 4), (-2, 36), (√6, 32), and (-√6, 32).
To sketch the region bounded by the curves, we can plot the two curves and shade the area between them:
The area of this region can be found by integrating the difference between the two curves with respect to x:
A = ∫[√6, 2] [(x⁴ - 4) - (2x² - 20)] dx
Simplifying, we get:
A = ∫[√6, 2] (x⁴ - 2x² + 16) dx
Integrating term by term, we get:
A = [x⁵/5 - 2x³/3 + 16x]√6 to 2
Evaluating this expression, we get:
A ≈ 72.75
So, the area of the region bounded by the curves is approximately 72.75 square units.

work out the area of a rectangle with base, b = 20mm and perimeter, p = 50mm.
Answers
Answer:
100
Step-by-step explanation:
If the base is 20, then 2 of the sides must have a length of 20. This means that the TOTAL length of the remaining sides is 10. (20*2) + (10) = 50. If we divide that in half, we get 5. That is the side length of the remaining 2 sides. This means that 20 * 5 will give us the area (b*h).
Given,
base, b = 20mm &
perimeter, p = 50mm.
the area of the rectangle : (50 – 20 × 2) ÷ 2 = 5. 5 × 20 = 100 [tex]mm^{2}[/tex].
Perimeter and area are two important and basic mathematical subjects. They help quantify the physical space and also provide a more advanced foundation of mathematics in algebra, trigonometry, and calculus. Perimeter is a measure of the distance around a shape, and area indicates how much area the shape covers.
The perimeter of a 2D shape is the distance around the shape. You can imagine wrapping a string around a triangle. The length of this cord is around the triangle. Or, if you're traveling outside the park, take a route that goes around the edge of the park.

find the area of following figure...?
Answers
Answer:
33600 m²
Step-by-step explanation:
The top and bottom horizontal sides are parallel, so this is a trapezoid with bases DC and AB. The height is BC.
area of trapezoid = (a + b)h/2
where a and b are the lengths of the bases, and h is the height.
We need to find the height, BC.
Drop a perpendicular from point A to segment DC. Call the point of intersection E. E is a point on segment DC.
DE + EC = DC
EC = AB = 360 m
DC = 600 m
DE + 360 m = 600 m
DE = 240 m
Use right triangle ADE to find AE. Then BC = AE.
DE² + AE² = AD²
DE² + 240² = 250²
DE² = 62500 - 57600
DE² = 4900
DE = √4900
DE = 70
BC = 70 = h
area = (a + b)h/2
area = (600 m + 360 m)(70 m)/2
area = 33600 m²
Answer:
33,600 m^2.
Step-by-step explanation:
This is a trapezium, so
Area = (h/2)(a + b)
= (h/2) ( 360 + 600)
= 960h / 2
= 480h,
We find the value of h using Pythagoras:
250^2 = h^2 + (600-360)^2
h^2 = 250^2 - 240^2 = 4900
h = 70.
So the Area = 70 * 480
= 33,600 m^2

The standard form of the given equation is: y = -3(x-6)²+35.
In mathematics, the most typical way to represent a specific element is called standard form.
A standard form is a way to express a particular mathematical idea, such as an equation, number, or expression, in prose that adheres to a set of criteria.
Given equation is: y = − 3x² + 36x - 73
In order to convert to the standard form,
y+73 = −3x² +36x
Subtract 108 from both the sides,
y+73-108 = −3x² +36x-108
y-35 = -3(x² -12x+36)
y-35 = -3(x-6)²
y = -3(x-6)²+35

The probability that more than 4 weigh more than 20 pounds is:
[tex]P(X > 4) = 1 - P(X \leq 4)[/tex]
In which:
[tex]P(X \leq 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)[/tex]
Then:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{10,0}.(0.4)^{0}.(0.6)^{10} = 0.0061[/tex]

[tex]P(X > 4) = 1 - P(X \leq 4) = 1 - 0.6325 = 0.3675[/tex]
0.3675 = 36.75% probability that more than 4 weigh more than 20 pounds.
The probability that fewer than 3 weigh more than 20 pounds is:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0061 + 0.0403 + 0.1209 = 0.1673
0.1673 = 16.73% probability that fewer than 3 weigh more than 20 pounds.

The length of a rectangle is 6 inches more than its width. Its area is 91 square inches. The length is .
Answers
Answer:
13 in
Step-by-step explanation:
let w be width then length is w + 6
the area (A) of a rectangle is calculated as
A = length × width , then
A = w(w + 6) = 91 , that is
w² + 6w = 91 ( subtract 91 from both sides )
w² + 6w - 91 = 0 ← in standard quadratic form
(w + 13)(w - 7) = 0 ← in factored form
equate each factor to zero and solve for w
w + 13 = 0 ⇒ w = - 13
w - 7 = 0 ⇒ w = 7
however, w > 0 then w = 7
and length = w + 6 = 7 + 6 = 13 in

A. b(a)-2-9
B. b(a)-+9
OC. b(a)- +6
OD. b(a)-9-6
Answers
The inverse function of [tex]A(b) = 12 \cdot \frac{b + 9}2[/tex] is b(a) = a/6 - 9
How to determine the inverse function?The function is given as:
[tex]A(b) = 12 \cdot \frac{b + 9}2[/tex]
Divide 12 by 2
[tex]A(b) = 6 \cdot (b + 9)[/tex]
Rewrite the function as
[tex]a = 6 \cdot (b + 9)[/tex]
Divide both sides by 6
a/6 = b + 9
Subtract 9 from both sides
b = a/6 - 9
Express as a function
b(a) = a/6 - 9
Hence, the inverse function of [tex]A(b) = 12 \cdot \frac{b + 9}2[/tex] is b(a) = a/6 - 9

Answers
A system equations that can be used to determine after how many months the boys will owe the same amount is
60 x = $ 1000
20 y = $ 600
In mathematics, a system of equations, also known as a system of simultaneous or systems of equations, is a finite system of equations for which we have sought common solutions. A system of equations can be classified in a similar way to simple equations. A system of equations finds application in our everyday life in modeling problems where unknown values can be represented in the form of variables.
In algebra, a system of equations contains two or more equations and looks for common solutions to the equations. "A system of linear equations is a set of equations that are satisfied by the same set of variables."
We need to find a system equations that can be used to determine after how many months the boys will owe the same amount
Let lan take x months to pay $ 1000 to his parents
In 1 month Ian pays $60
In x months Ian pays =
60 x= $ 1000
Let Ken take y months to pay $ 600 to his parents
In 1 month Ian pays $20
In y months Ian pays =
20 y= $ 600

The triangle can be a right triangle
How to determine the triangle type?The side lengths are given as:
3, 3 and 3√2
If the triangle is a right triangle, then the following must be true
a^2 = b^2 + c^2
Where a is the longest side.
So, we have:
[tex](3\sqrt 2)^2 = 3^2 + 3^2[/tex]
Evaluate the expressions

BE is two units longer than a EDE is five units longer than a E and CE is 12 units longer than AE what is BD
Answers
Length of BD is 11 units.
The intersecting chords theorem or just the chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal.
Let length of AE be x
By intersecting chords theorem,
AE(ED) = BC(DE)
x(x + 12) = (x +2)(x +5)
x² + 12x= x² + 7x + 10
5x = 10
x = 2
BD = BE + DE
= x + x +7
= 2x + 7
= 2(2) + 7
= 11 units
