The volume of the solid formed by revolving the region bounded by the graphs y = √x and y = x^2 about the x-axis is approximately 2.667 cubic units.

What is the shell method for finding the volume of the solid?

The shell method for finding the volume of a solid formed by revolving a region about an axis is a method used to find the volume of the resulting solid by adding up the volumes of an infinite number of thin cylindrical shells.

In this case, the region bounded by the graphs y = √x and y = x^2 is revolved about the x-axis. To use the shell method, we first need to determine the height and radius of each cylindrical shell. The height of each shell is equal to the difference between the upper and lower bounds of the region, which is x^2 - √x. The radius of each shell is equal to the value of y at that point, which is either √x or x^2.

The volume of each shell can then be calculated as V = 2πr * h, where r is the radius and h is the height. To find the total volume, we need to integrate the volume of each shell over the interval of x.

The definite integral for the volume is given by:

∫_{0}^{1} 2π x * (x^2 - √x) dx

Evaluating this definite integral gives a volume of approximately 2.667.

Hence, the volume of the solid formed by revolving the region bounded by the graphs y = √x and y = x^2 about the x-axis is approximately 2.667 cubic units.

Answer:

P = 24.997 cm

Step-by-step explanation:

the perimeter (P) is the sum of the 2 radii and the arc

the arc length is calculated as

arc = circumference of circle × fraction of circle

      = 2πr × [tex]\frac{90}{360}[/tex] ( r is the radius , here r = 7 )

      = 2 × 3.142 × 7 × [tex]\frac{1}{4}[/tex]

      = 43.988 ÷ 4

      = 10.997 cm

Then

P = 10.997 + 7 + 7 = 24.997 cm

It appears that for any ax + b, a combination of ax + b and 2a+d equals 1. This can be proven by setting P(x) = -ax - b and Q(x) = 2a+d.

(a) No combination of 2x + 5 and 3 can equal 1.

Let P(x) and Q(x) be two integer polynomials such that P(x)·(2x + 5) + Q(x)·3 = 1.

This can be written as P(x)·2x + P(x)·5 + Q(x)·3 = 1.

Rearranging, we get P(x)·2x + (P(x)·5 + Q(x)·3) = 0

This implies that P(x)·2x = -(P(x)·5 + Q(x)·3).

Since both P(x) and Q(x) are integer polynomials, it follows that P(x)·2x and (P(x)·5 + Q(x)·3) are both integers.

However, this is impossible since the left hand side is an even integer, while the right hand side is an odd integer.

Therefore, no combination of 2x + 5 and 3 can equal 1.

(b) A combination of 2x + 5 and 4 that equals 1 is P(x) = -2x - 5 and Q(x) = 4.

(c) No combination of 15x+9 and 25 equals 1. However, a combination of 15x+9 and 20 equals 1. This can be seen by setting P(x) = -15x - 9 and Q(x) = 20.

(d) Some examples of ax + b and d combinations that equal 1 are:

2x + 5 and 4

3x + 4 and 7

4x + 3 and 9

5x + 2 and 11

It appears that for any ax + b, a combination of ax + b and 2a+d equals 1. This can be proven by setting P(x) = -ax - b and Q(x) = 2a+d.

By using the induction, the equation 1+ 4 + 9 + ...........+n² = n(n-1)(2n-1)/6 where n ≥ 1 is proved.

The term induction in math is defined as a technique of proving a statement, theorem or formula which is thought to be true, for each and every natural number n.

In this case, we want to use induction to prove the equation:

=> 1 + 4 + 9 + ... + n² = n(n + 1)(2n + 1)/6 for all integers n ≥ 1.

To start the induction proof, we first prove that the statement is true for the base case n = 1.

The left side of the equation is 1, and the right side is

=> 1 * (1 + 1) * (2 * 1 + 1) / 6 = 1 * 2 * 3 / 6 = 1,

so the equation is true for n = 1.

Next, we assume that the equation is true for some integer k, where k ≥ 1. This means that:

=> 1 + 4 + 9 + ... + k² = k(k + 1)(2k + 1)/6.

Now, we use this information to prove that the statement is true for k + 1. The left side of the equation for k + 1 is:

=> 1 + 4 + 9 + ... + k² + (k + 1)².

This is equal to k(k + 1)(2k + 1)/6 + (k + 1)² by the induction hypothesis.

The right side of the equation for k + 1 is:

=> (k + 1)(k + 2)(2k + 3) / 6.

We can simplify this to:

=> (k² + 3k + 3) * (k + 2) / 6 = (k² + 3k + 3)(k + 2) / 6.

Finally, we need to show that these two expressions are equal:

=>k(k + 1)(2k + 1)/6 + (k + 1)² = (k² + 3k + 3)(k + 2) / 6.

Expanding both sides and cancelling common terms, we find that:

=> k³ + 3k² + 2k + k² + 3k + 3 = 2k³ + 9k² + 12k + 6.

This shows that the equation is true for k + 1, and by induction, it is true for all integers n ≥ 1.

The angular acceleration of the system times the system's radius, which is 40 cm, or 0.4 m, gives rise to the tangential acceleration at the system's farthest edge at time t = 0.5 s. Thus, 0.4 m/s2 is the tangential acceleration.

The radius of the system multiplied by the system's angular acceleration gives the tangential acceleration of a point at its furthest edge. The system's radius in this instance is 40 cm, or 0.4 metres, and the time is 0.5 seconds. As a result, the tangential acceleration at time t = 0.5 s is equal to the system's angular acceleration times its radius, which is 0.4 m. We multiply the angular acceleration by the system's radius, which is 0.4 m, to determine the tangential acceleration. Thus, 0.4 m/s2 is the tangential acceleration at time t = 0.5 s. This indicates that a point on the system's outermost edge accelerates by 0.4.

The solution to the initial value problem y'' - 2y' + 2y = e^(-x) with y(0) = 0 and y'(0) = 0 is given by y(x) = x - e^(-x) + x^2.

y'' - 2y' + 2y = e^(-x)

y(0) = 0, y'(0) = 0

Let Yp = A + Bx + Cx^2

Yp' = B + 2Cx

Yp'' = 2C

Substituting into the original equation yields:

2C - 2(B + 2Cx) + 2(A + Bx + Cx^2) = e^(-x)

Collecting terms gives:

2C - 2B = 0, 2C - 2A = e^(-x), and 2C = 2Bx

Solving for C yields C = Bx, for B yields B = 2C, and for A yields A = 2C - e^(-x).

Therefore, the general solution is

y = (Bx - e^(-x)) + Bx^2

Using the initial conditions, we get

y(0) = 0 = (B(0) - e^(0)) + B(0)^2

0 = -1 + B(0)^2

Step-by-step explanation:

a) To calculate how long it takes Penny to pay off the loan, we can use the formula:

n = log(P/A) / log(1 + r/12),

where n is the number of months, P is the initial loan amount ($4500), A is the monthly payment ($160), and r is the annual interest rate (3%).

n = log(4500/160) / log(1 + 0.03/12)

n = log(28.125) / log(1.0025)

n = 3.7062

Rounding up, it takes Penny 4 months to pay off the loan.

b) To calculate the amount of Penny's final payment, we can use the formula:

P = A * (1 - (1 + r/12)^-n),

where P is the remaining balance, A is the monthly payment ($160), n is the number of months (4), and r is the annual interest rate (3%).

P = 160 * (1 - (1 + 0.03/12)^-4)

P = 160 * (1 - (1.0025)^-4)

P = $157.92

Therefore, it takes Penny 4 months to pay off the loan and her final payment is $157.92.
