Evaluate ·S= 1. What is a²? 2. What is a? 3. What is u²? 4. What is u? 5. What is du? 6. What is the result of integration?
To evaluate the expression S = ∫(a²)du, we can break it down into smaller components. In this case, a² represents the square of a variable a, and a represents the value of the variable itself. Similarly, u² represents the square of a variable u, and u represents the value of the variable itself. Evaluating du involves finding the differential of u. Finally, integrating the expression ∫(a²)du results in a new function that represents the antiderivative of a² with respect to u.
1. The term a² represents the square of a variable a. It implies that a is being multiplied by itself, resulting in a².
2. To determine the value of a, we would need additional information or context. Without a specific value or equation involving a, we cannot calculate its numerical value.
3. Similarly, u² represents the square of a variable u. It implies that u is being multiplied by itself, resulting in u².
4. Like a, the value of u cannot be determined without further information or context. It depends on the specific problem or equation involving u.
5. du represents the differential of u, which signifies a small change or infinitesimal increment in the value of u. It is used in the process of integration to indicate the variable of integration.
6. The result of evaluating ∫(a²)du would be a function that represents the antiderivative of a² with respect to u. Since there is no specific function or limits of integration provided in the expression, we cannot determine the exact result of the integration without additional information.
In summary, without specific values for a, u, or the limits of integration, we can only describe the properties and meaning of the components in the expression S = ∫(a²)du.

Answer:
Use tan trig ratio:
\(\sf tan(\theta)=\dfrac{O}{A}\)
where \(\theta\) is the angle, O is the side opposite the angle, and A is the side adjacent the angle
Given:
\(\theta\) = 39°O = 10\(x\) = ASubstituting these values into the formula:
\(\implies \tan(39)=\dfrac{10}{x}\)
Multiplying both sides by \(x\):
\(\implies x\tan(39)=10\)
Dividing both sides by \(\tan(39)\) :
\(\implies x=\dfrac{10}{\tan(39)}\)

Determine the general solution for the differential equation in (i), and also determine the solution to the initial value problem in (ii): (i) dy/dt= (ty−2t+4y−8)/(ty+3t−y−3) (ii) ty+t 2 dy/dt =y where y(−1)=−1
Answer:
To determine the general solution for the differential equation dy/dt = (ty - 2t + 4y - 8)/(ty + 3t - y - 3), we can rewrite it in the form dy/dt = (t - 2)/(t - 1).By separating variables and integrating, we find the general solution as y = t + C(t - 1), where C is an arbitrary constant.
For the initial value problem ty + t^2 dy/dt = y with y(-1) = -1, we substitute the given initial condition into the general solution to find the specific solution.
(i) To find the general solution for dy/dt = (ty - 2t + 4y - 8)/(ty + 3t - y - 3), we can simplify the right-hand side to (t - 2)/(t - 1) by factoring and canceling common terms. Next, we can separate variables by multiplying both sides by (t - 1) and dt, yielding (t - 1)dy = (t - 2)dt. Integrating both sides gives us y = t + C(t - 1), where C is an arbitrary constant.
(ii) For the initial value problem ty + t^2 dy/dt = y with y(-1) = -1, we substitute the initial condition y(-1) = -1 into the general solution. Plugging in t = -1 and y = -1 into y = t + C(t - 1), we have -1 = -1 + C(-1 - 1). Simplifying this equation gives us C = 0. Therefore, the solution to the initial value problem is y = t.

let r = x i y j z k and r = |r|. if f = r/r p, find div f. (enter your answer in terms of r and p.) div f = is there a value of p for which div f = 0? (if an answer does not exist, enter dne.) p =
The 3(1/√(x² + y² + z²)) is a nonzero constant, there is no value of p that makes the divergence zero.
To find the divergence of the vector field f = r/r p, we need to compute the dot product of the gradient operator (∇) with f.
The gradient operator in Cartesian coordinates is given by:
∇ = ∂/∂x i + ∂/∂y j + ∂/∂z k
And the vector field f can be written as:
f = r/r p = (xi + yj + zk)/(√(x² + y² + z²)) p
Now, let's compute the dot product:
∇ · f = (∂/∂x i + ∂/∂y j + ∂/∂z k) · [(xi + yj + zk)/(√(x² + y² + z²)) p]
Taking each component of the gradient operator and applying the dot product, we get:
∂/∂x · [(xi + yj + zk)/(√(x² + y² + z²)) p] = (∂/∂x)(x/√(x² + y² + z²)) p
= (1/√(x² + y² + z²)) p
∂/∂y · [(xi + yj + zk)/(√(x² + y² + z²)) p] = (∂/∂y)(y/√(x² + y² + z²)) p
= (1/√(x² + y² + z²)) p
∂/∂z · [(xi + yj + zk)/(√(x² + y² + z²)) p] = (∂/∂z)(z/√(x² + y² + z²)) p
= (1/√(x² + y² + z²)) p
Adding up these components, we have:
∇ · f = (1/√(x² + y² + z²)) p + (1/√(x² + y² + z²)) p + (1/√(x² + y² + z²)) p
= 3(1/√(x² + y² + z²)) p
So, the divergence of f is given by:
div f = 3(1/√(x² + y² + z²)) p
Now, we need to find if there exists a value of p for which div f = 0. Since 3(1/√(x² + y² + z²)) is a nonzero constant, there is no value of p that makes the divergence zero. Therefore, the answer is "dne" (does not exist).

amelia’s bank account earns interest annually. the equation shows her starting balance of $200 and her balance at the end of four years, $220.82. at what rate, r, did amelia earn interest?
Answer: $50
Step-by-step explanation:
Since from sentence 6 we know ¬C, we can apply modus ponens to sentence 7:
If sentence 6 states that ¬C is true, and sentence 7 presents a conditional statement with C as the antecedent and Q as the consequent, we can use modus ponens to infer that Q is false.
Modus ponens is a deductive reasoning rule that allows us to derive a conclusion from a conditional statement and its antecedent. Therefore, we can apply modus ponens to sentence 7 given that we know ¬C from sentence 6.
Since from sentence 6 we know ¬C, we can apply modus ponens to sentence 7. To do this, follow these steps:
1. Identify the premises: One premise is sentence 6, which states ¬C. The other premise should be a conditional statement, such as "If ¬C, then P" (replace P with the relevant proposition).
2. Apply modus ponens: Modus ponens is a rule of inference that allows us to deduce a conclusion from the given premises. If we have the premises "If ¬C, then P" and "¬C", we can conclude "P" using modus ponens.
3. State the conclusion: After applying modus ponens, we can conclude "P" based on the given premises, which include sentence 6 (¬C) and the conditional statement.

What is circular cylinder?A cylinder whose bases are circular in shape and parallel to each other is called the right circular cylinder. It is a three-dimensional shape.
Given that the radius of a sphere R = √3
Let the radius of the cylinder is r and the height of the cylinder is h.
than.
r² = R² − h²/4
and Vc = πr²h
⇒ Vc = π(R² − h²/4)h
⇒ Vc = πR²h − πh³/4
dVc/dh = πR² − 3πh²/4
(dVc/dh)R=√3 = 3π − 3πh²/4
For maximum or minimum volume,
dVc/dh = 0
⇒ 3π − 3πh²/4 = 0
⇒ 3πh²/4 = 3π
⇒ 3πh² = 3π*4
⇒ h² = 4
⇒ h=2
Also, dVc/dh changes sign from positive to negative in the neighborhood of h=2. Hence, h=2 is a maximum point.
r² = R² − h²/4
⇒ r² = (√3)² - 2²/4
⇒ r² = 3 - 1
⇒ r² = 2
⇒ r = √2
So, the height is 2 and radius is √2 of the largest right circular cylinder

Find an equation for the line tangent to the graph of the given function at the indicated point. 8 3) f(x): () = at at (4,2) X 1 4) f(x)=x2-x at (4, 12)
(a) tangent line to the graph of f(x) = x^3 at the point (4,2).
(b) equation of the tangent line to the graph of f(x) = x^2 - x at the point (4,12).
(a) To find the equation of the tangent line to the graph of f(x) = x^3 at the point (4,2), we need to find the slope of the tangent line at that point. We can do this by taking the derivative of f(x) with respect to x and evaluating it at x = 4. The derivative of f(x) = x^3 is f'(x) = 3x^2. Evaluating f'(x) at x = 4 gives us the slope of the tangent line. Once we have the slope, we can use the point-slope form of a linear equation to write the equation of the tangent line.
(b) Similarly, to find the equation of the tangent line to the graph of f(x) = x^2 - x at the point (4,12), we differentiate f(x) to find the derivative f'(x). The derivative of f(x) = x^2 - x is f'(x) = 2x - 1. Evaluating f'(x) at x = 4 gives us the slope of the tangent line. Using the point-slope form, we can write the equation of the tangent line.
In both cases, the equations of the tangent lines will be in the form y = mx + b, where m is the slope and b is the y-intercept.
