Find the particular antiderivative of the following derivative that satisfies the given condition. C''(x)=4x2-3x ; C(0)=2000
The particular antiderivative that satisfies the given condition is: C(x) = (4/9)x^4 - (9/8)x^3 + K1x + 2000
To find the particular antiderivative (or integral) of the given derivative \(C''(x) = 4x^2 - 3x\) that satisfies the condition C(0) = 2000, we need to integrate the given function twice.
First, we integrate C''(x) to find C'(x):
\(C'(x) = ∫ (4x^2 - 3x) dx\)
To find the antiderivative of \(4x^2\), we use the power rule for integration: the power of x increases by 1 and is divided by the new power. Similarly, the antiderivative of -3x is \(-(3/2)x^2\).
\(C'(x) = ∫ (4x^2 - 3x) dx = (4/3)x^3 - (3/2)x^2 + K1\)
Here, K1 is the constant of integration. Next, we integrate C'(x) to find C(x):
\(C(x) = ∫ (C'(x)) dx = ∫ ((4/3)x^3 - (3/2)x^2 + K1) dx\)
To find the antiderivative of \((4/3)x^3\), we again use the power rule for integration. Similarly, the antiderivative of \(-(3/2)x^2\) is \(-(3/2)(1/3)x^3\).
The constant of integration K1 will also be integrated with respect to x, resulting in another constant of integration, K2.
\(C(x) = (1/3)(4/3)x^4 - (1/2)(3/2)x^3 + K1x + K2\)
Simplifying further, we have:
\(C(x) = (4/9)x^4 - (9/8)x^3 + K1x + K2\)
Now, we can apply the initial condition C(0) = 2000 to find the particular solution for K2:
\(C(0) = (4/9)(0)^4 - (9/8)(0)^3 + K1(0) + K2 = 2000\)
Since all the terms involving x become zero when x = 0, we have:
K2 = 2000
Therefore, the particular antiderivative that satisfies the given condition is: \(C(x) = (4/9)x^4 - (9/8)x^3 + K1x + 2000\)

If sin x= (sqrt 2)/2 and tan x=-1 what is sec x
Answer:
\(-\frac{2}{\sqrt{2}}\) or \(-\sqrt{2}\)
Step-by-step explanation:
\(\sec{x}\) is the reciprocal of \(\cos{x}\), or in symbols: \(\sec{x}=\frac{1}{\cos{x}}\). \(\tan{x}\) is also the ratio of \(\sin{x}\) to \(\cos{x}\), and we can multiply both sides of the equation \(\tan{x}=\frac{\sin{x}}{\cos{x}}\) by \(\frac{1}{\sin{x}}\) to get the equation \(\frac{\tan{x}}{\sin{x}}=\frac{1}{\cos{x}}\). Of course, this is just the definition of \(\sec{x}\), so we can rewrite this fact as \(\sec{x}=\frac{\tan{x}}{\sin{x}}\).
In this problem, we're given that \(\sin{x}=\frac{\sqrt{2} }{2}\) and \(\tan{x}=-1\), so plugging those two values into our equation gives us
\(\sec{x}=\dfrac{-1}{\frac{\sqrt{2}}{2}} =-\frac{2}{\sqrt{2}}\)
We could leave our solution as \(-\frac{2}{\sqrt{2}}\), or we could rationalize the denominator to get a solution of
\(-\frac{2}{\sqrt{2}}\cdot\frac{\sqrt{2}}{\sqrt{2}}=-\frac{2\sqrt{2}}{2}=-\sqrt{2}\)

Step-by-step explanation:
we wish to construct a rectangular auditorium with a stage shaped as a semicircle of radius $r$, as shown in the diagram below (white is the stage and green is the seating area). for safety reasons, light strips must be placed on the perimeter of the seating area. if we have $45\pi 60$ meters of light strips, what should $r$ be so that the seating area is maximized?
To maximize the seating area while using 45π + 60 meters of light strips, the radius of the semicircular stage should be approximately 29π/3 - 5 meters.
To maximize the seating area, we need to determine the dimensions of the rectangular auditorium that will give us the largest possible area while using the given length of light strips.
Let the length of the rectangular auditorium be L, and its width be W.
The seating area consists of the rectangular portion minus the semicircular stage. So, the seating area's length is L - 2r (subtracting the semicircle's diameter) and the seating area's width is W - 2r.
The perimeter of the seating area is the sum of the lengths of its four sides, excluding the semicircular stage. The perimeter is given as 45π + 60 meters.
Perimeter = 2(L - 2r) + 2(W - 2r) + πr = 45π + 60
Simplifying: 2L + 2W - 8r + πr = 45π + 60
Rearranging: 2L + 2W = 8r + 44π + 60
The area of the seating area is given by A = (L - 2r)(W - 2r).
We want to maximize A, so we need to express it in terms of a single variable. Since we have an equation with two variables (L and W), we can rewrite one of the variables in terms of the other.
Rearranging the perimeter equation: 2L + 2W = 8r + 44π + 60
Solving for L: L = (8r + 44π + 60 - 2W) / 2
Substituting L in terms of W into the area equation: A = [(8r + 44π + 60 - 2W) / 2 - 2r] (W - 2r)
Simplifying: A = (4r + 22π + 30 - W) (W - 2r)
Now we have the area equation in terms of a single variable, W. To maximize A, we can take the derivative of A with respect to W, set it equal to zero, and solve for W.
dA/dW = 2(4r + 22π + 30 - W) - (W - 2r) = 0
Solving for W: 8r + 44π + 60 - W = W - 2r
Simplifying: 10r + 44π + 60 = 2W
W = 5r + 22π + 30
Now that we have W in terms of r, we can substitute this expression back into the area equation to get the area in terms of r only.
A = (4r + 22π + 30 - (5r + 22π + 30)) ((5r + 22π + 30) - 2r)
Simplifying: A = (r - 22π) (3r + 22π + 30)
Expanding: A = 3r² + 8rπ + 30r - 66πr - 660π
Now, to find the maximum area, we can take the derivative of A with respect to r, set it equal to zero, and solve for r.
dA/dr = 6r + 8π + 30 - 66π = 0
Simplifying: 6r - 58π + 30 = 0
6r = 58π - 30
r = (58π - 30) / 6
r ≈ 29π/3 - 5
Therefore, to maximize the seating area while using 45π + 60 meters of light strips, the radius of the semicircular stage should be approximately 29π/3 - 5 meters.

The value of tan(3π/4) is -1. How does the value of tan(3π/4 – π) compare? Explain your reasoning.
Answer:
The value of tan(3π/4) is indeed -1.
Now, to evaluate tan(3π/4 - π), we can use the following trigonometric identity:
tan(a - b) = (tan(a) - tan(b)) / (1 + tan(a)*tan(b))
Applying this identity to the expression tan(3π/4 - π), we get:
tan(3π/4 - π) = (tan(3π/4) - tan(π)) / (1 + tan(3π/4)*tan(π))
Substituting the values of tan(3π/4) = -1 and tan(π) = 0, we get:
tan(3π/4 - π) = (-1 - 0) / (1 + (-1)*0) = -1
So the value of tan(3π/4 - π) is also -1, which is the same as the value of tan(3π/4).
In other words, the value of tan(3π/4 - π) is equal to the value of tan(3π/4) because π is equal to 180 degrees, which is a full rotation. Subtracting a full rotation from an angle simply results in an equivalent angle in the opposite direction. Thus, the values of tangent for both angles remain the same.

What is properties of equality?"Properties of equality represents the relation between two equal quantities after applying any operation on left hand side same has to be applied on the right hand side to make the balance in the given equation."
According to the question,
(3 / 2) = k + (11 / 2)
Here given operation is addition,
Apply inverse operation of addition,
Case1: Subtract 11/2 from both the sides we have,
(3 /2) - (11 / 2) = k + (11/ 2) - (11 / 2)
⇒ ( -8 /2) = k
⇒ k = -4
Case 2. Add ( - 11 /2) to both the sides we have,
( 3/ 2) + ( -11 /2) = k +( 11 /2) + (-11/ 2)
⇒( -8 /2) = k
⇒k = -4
Hence, solution of k = -4 after applying the property of equality of addition and subtraction.

Show that the functions f(t) = t and g(t) = e^2t are linearly independent linearly independent by finding its Wronskian.
f(t) = t and g(t) = \(e^{(2t)\) form a linearly independent set of functions.
To show that the functions f(t) = t and g(t) = \(e^{(2t)\) are linearly independent, we can calculate their Wronskian and verify that it is nonzero for all values of t.
The Wronskian of two functions f(t) and g(t) is defined as the determinant of the matrix:
| f(t) g(t) |
| f'(t) g'(t) |
Let's calculate the Wronskian of f(t) = t and g(t) = \(e^{(2t)\):
f(t) = t
f'(t) = 1
g(t) = \(e^{(2t)\)
g'(t) = 2\(e^{(2t)\)
Now we can form the Wronskian matrix:
| t \(e^{(2t)\)|
| 1 2\(e^{(2t)\) |
The determinant of this matrix is:
Det = (t * 2\(e^{(2t)\)) - (1 * \(e^{(2t)\))
= 2t\(e^{(2t)\) - \(e^{(2t)\)
= \(e^{(2t)\) (2t - 1)
We can see that the determinant of the Wronskian matrix is not zero for all values of t. Since the Wronskian is nonzero for all t, it implies that the functions f(t) = t and g(t) = \(e^{(2t)\) are linearly independent.
Therefore, f(t) = t and g(t) = \(e^{(2t)\) form a linearly independent set of functions.

The length of a rectangle is 6 inches longer than its width. What are the possible widths if the area of the rectangle is at least 667 square inches?
Answer:
D, \(w\geq 23\)
Step-by-step explanation:
The length is 6 inches longer than it's width, therefore:
\(l=w+6\)
The area of the rectangle is AT LEAST 667 square inches, so:
\(lw\geq 667\)
Now, we have a system of two equations:
\(\left \{ {{l=w+6} \atop {lw\geq 667}} \right.\)
We want to isolate the width, so substitute the first equation into the second to eliminate the length.
\((w+6)w\geq 667\)
Simplify:
\(w^2+6w\geq 667\)
Since we now have a polynomial equation that needs to be factored, set the value of one side to 0.
\(w^2+6w-667\geq 0\)
Now factor the equation:
\((w-23)(w+29)\geq 0\)
Taking each factor individually, we find the following:
\(w\geq 23\\w\geq -29\)
Since a negative width doesn't make any sense, we can eliminate that solution, and we are left with the correct answer!
\(w\geq 23\)
15 more than twice a number is 37. Wht is the number
A number which is 15 more than twice a number is 37 is 11.
Let the number be N.
Let's set up the equation.
A number is 15 more than twice a number is 37,
2N + 15 = 37
Let's subtract 15 from both sides.
2N = 22

In year N, the 300th day of the year is a Tuesday. In year N+1, the 200th day is also a Tuesday. On what day of the week did the 100thth day of year N-1 occur ?
Therefore, if the 300th day of year N is a Tuesday, the 100th day of year N-1 will be a Sunday.
To determine the day of the week on the 100th day of year N-1, we need to analyze the given information and make use of the fact that there are 7 days in a week.
Let's break down the given information:
In year N, the 300th day is a Tuesday.
In year N+1, the 200th day is also a Tuesday.
Since there are 7 days in a week, we can conclude that in both years N and N+1, the number of days between the two given Tuesdays is a multiple of 7.
Let's calculate the number of days between the two Tuesdays:
Number of days in year N: 365 (assuming it is not a leap year)
Number of days in year N+1: 365 (assuming it is not a leap year)
Days between the two Tuesdays: 365 - 300 + 200 = 265 days
Since 265 is not a multiple of 7, there is a difference of days that needs to be accounted for. This means that the day of the week for the 100th day of year N-1 will not be the same as the given Tuesdays.
To find the day of the week for the 100th day of year N-1, we need to subtract 100 days from the day of the week on the 300th day of year N. Since 100 is a multiple of 7 (100 = 14 * 7 + 2), the day of the week for the 100th day of year N-1 will be two days before the day of the week on the 300th day of year N.
