find the area of the region enclosed by one loop of the curve. r = sin(4θ)
π/16 is the area enclosed by the curve r= sin(4θ)
The given curve is polar curve and hence the area of the polar curve is given by:
Let A be the area of the curve so,
A = [tex]\int\limits^b_a {\frac{1}{2}r^2 } \, d\theta[/tex]
where a and b is the boundary at which r=0
so after equation r=0
sin(4θ) =0
=> sin(4θ) =0
=> 4θ = 0,π
=> θ = 0, π/4
so a=0 , b= π/4
now
A = [tex]\int\limits^b_a {\frac{1}{2}r^2 } \, d\theta[/tex] ------(i)
so [tex]r^2[/tex] = (sin(4θ))^2
=> [tex]sin^2[/tex]( 4θ )
ans we know that
cos(2α) = 1 - [tex]2sin^2[/tex]2 α
so [tex]sin^2[/tex]= (1- cos(8θ) )/2
putting the value of r in the equation (i) we get :-
A = [tex]\int\limits^b_a {\frac{1}{4} *(1-cos8\theta) } \, d\theta[/tex]
=> 1/4* [tex]\int\limits^b_a {(1-cos8\theta) } \, d\theta[/tex]
here a=0 and b=π/4
after putting the value and solving the integral
A = π/16
so A is the area enclosed by r=sin(4θ) is π/16

What are the vertex and range of y = |2x 6| 2? (0, 2); 2 < y < [infinity] (0, 2); −[infinity] ≤ y < [infinity] (−3, 2); 2 < y < [infinity] (−3, 2); −[infinity] ≤ y < [infinity]
Although part of your question is missing, you might be referring to this full question: What are the vertex and range of y = |2x + 6| + 2?
(0, 2); 2 < y < ∞
(0, 2); −∞ ≤ y < ∞
(−3, 2); 2 < y < ∞
(−3, 2); −∞ ≤ y < ∞
The vertex of the function is (–3, 2) and the range of the function is 2 < y < ∞.
The given modulus function:
y = |2x + 6| + 2
Now, we get two equations out of the absolute value function:
y = 2x + 6 + 2
y = 2x + 8
and
y = –2x – 6 + 2
y = –2x – 4
The vertex of the function will be at a point where these two equations are equal. So, we can calculate the vertex as follows:
2x + 8 = –2x – 4
2x + 2x = –4 – 8
4x = –12
x = –3
If x = –3, then y = 2(–3) + 8 = –6 + 8 = 2
Thus, the vertex of the function is (–3, 2).
Now, the values that y can take will range from 2 to infinity as y cannot take values below the vertex.
Thus, the range of the function is 2 < y < ∞.

Belinda is thinking about buying a house for $286,000. The table below shows the projected value of two different houses for three years:
Number of years 1 2 3
House 1 (value in dollars) 294,580 303,417.40 312,519.92
House 2 (value in dollars) 295,000 304,000 313,000
Part A: What type of function, linear or exponential, can be used to describe the value of each of the houses after a fixed number of years? Explain your answer. (2 points)
Part B: Write one function for each house to describe the value of the house f(x), in dollars, after x years. (4 points)
Part C: Belinda wants to purchase a house that would have the greatest value in 25 years. Will there be any significant difference in the value of either house after 25 years? Explain your answer, and show the value of each house after 25 years. (4 points)
Answer:
putting more than question is against app rules but alr
Part A: The value of each of the houses after a fixed number of years can be described by a linear function. This is because the value of each house increases at a constant rate, with the same amount added each year.
Part B: The function for House 1 could be written as f(x) = 294,580 + 8,937.6x, and the function for House 2 could be written as f(x) = 295,000 + 9,000x.
Part C: After 25 years, the value of House 1 will be approximately $750,834.40, and the value of House 2 will be approximately $753,000. The difference in value between the two houses after 25 years will be approximately $2,165.60, which is not a significant difference in the overall value of the houses. Therefore, either house would be a good choice for Belinda to purchase.

We are given the two equations are:
10x + 7y + z = 4---------(1)
[tex]\frac{x^2}{25} +\frac{y^2}{9} =1-------------(2)[/tex]
equation(1) is written as
z = 4 - 10x - 7y-----------(3)
The surface area is given by the equation:
A(S) = ∫∫√[(∂f/∂x)² + (∂f/∂y)² + 1]dA------------(4)
compare equation(4) with equation(3) we get the values of ∂f/∂x and
∂f/∂y
∂f/∂x = -10
∂f/∂y = -7
substitute these values in equation(4)
A(S) = ∫∫√[(-10)² + (-7)² + 1]dA
A(S) = ∫∫√[100 + 49 + 1]dA
A(S) = ∫∫√[150]dA
A(S) = √150 ∫∫dA
Where ∫∫dA is the elliptical cylinder
From the general form of an area enclosed by an ellipse with the formula;
comparing x²/a² + y²/b² = 1 with x²/25 + y²/9 = 1, from that we get the values of a and b
a = 5 and b = 3
So, the area of the elliptical cylinder = πab

suppose that 90% of the patients with a certain disease can be cured with a certain drug. what is the approximate probability that, of 50 such patients, at least 45 can be cured with the drug?
The approximate probability that at least 45 of 50 patients can be cured with the drug is 0.788.
To find the approximate probability that at least 45 of 50 patients can be cured with the drug, we can use the binomial formula. The binomial formula allows us to calculate the probability of a certain number of success out of a set of trials given a certain probability of success for each trial. In this case, we have a probability of success of 0.9 and 50 trials. Therefore, the probability of at least 45 of the 50 patients being cured with the drug is 0.788.

Answer:
x = 1 y = 0
Step-by-step explanation:
-8x + y = -8
6x - y = 6
y have the same coefficient but one is negative and the other is positive therefore we add both the equations
we get:
-2x = -2
divide both sides by -2
x = 1
now as we have the value of x we can input this into any one of the starting equations
-8x + y =-8
-8(1) +y = -8
-8 + y = -8
add 8 to both sides
y = 0
Answer:
(1, 0 )
Step-by-step explanation:
- 8x + y = - 8 → (1)
6x - y = 6 → (2)
adding (1) and (2) term by term will eliminate y
- 2x + 0 = - 2
- 2x = - 2 ( divide both sides by - 2 )
x = 1
substitute x = 1 into either of the 2 equations and solve for y

- 8(1) + y = - 8
- 8 + y = - 8 ( add 8 to both sides )
y = 0

the 6-kg smooth cylinder is supported by the spring having a stiffness of kab = 120 n/m
When a spring of stiffness K = 120N/m supporting a smooth cylinder of mass 6kg is subjected to a force of 60N, the velocity it moves downward when compressed a distance of 0.2m is 1.79m/s.
Therefore, the answer is 1.79m/s.
The compression of spring, say x₀ at equilibrium position can be determined by
F = Kx₀
mg = Kx₀
6 × 9.81 = 120 × x₀
Therefore x₀ = 0.4905m
When force F = 60N is applied the spring is compressed more and let new compression of spring be x₁. Then when string compresses additional s distance
x₁ = x₀ + s
Then spring force, F₁ = Kx₁
F₁ = 120 × (0.4905 + s)
F₁ = 58.86 + 120s
Let the cylinder accelerates downward at a m/s², then
60N + mg = ma + F₁
60 + 6×9.81 = 6a + 58.86 + 120s
a = (10 - 20s) m/s²
dv/dt = 10 - 20s
We know that ds/dt = v, that is 1/dt = v/ds
Therefore, vdv/ds = 10 - 20s
vdv = (10 - 20s)ds
Integrating both sides
v²/2 = 10s - 10s²
v = √(20s - 20s²)
At s = 0.2m,
v = √(20×0.2 - 20×0.2²)
v = 1.79m/s
--The question is incomplete, answering to the question below--
"The 6kg smooth cylinder is supported by the spring having a stiffness of kAB = 120 N/m.

a wooden cuboid has an open flame base with a square surface with 1.2 m sides and a height of 0.25 m. Find the surface of the cuboid.
Answer:
2.64 square meters.
Step-by-step explanation:
To find the surface area of a cuboid, you need to find the area of each of the six faces and add them together. A wooden cuboid with an open flame base that has a square surface with 1.2 meter sides and a height of 0.25 meters would have a surface area of 1.2 * 1.2 + 4 * (1.2 * 0.25) = 1.44 + 1.2 = 2.64 square meters. This is because the base of the cuboid has an area of 1.2 * 1.2 = 1.44 square meters, and each of the four sides has an area of 1.2 * 0.25 = 0.3 square meters. The total surface area of the cuboid is therefore the sum of these areas: 1.44 + 4 * 0.3 = 2.64 square meters.

In this case, the y-intercept of the first line is (-1/4,0), and the y-intercept of the second line is (-7/6,0). The difference between these y-intercepts is (-1/4 - (-7/6)) = 11/12. Therefore, the distance between the two parallel lines is 11/12.
