The half-life of a radioactive substance is the time it takes for half of the substance to decay. After [tex]10^6[/tex] years, 1/4 of the substance will remain.

The half-life of a radioactive substance is the time it takes for half of the substance to decay. In this case, the half-life is 4.5 × [tex]10^5[/tex] years.

To find out what fraction of the substance remains after [tex]10^6[/tex] years, we need to determine how many half-lives have occurred in that time.

Since the half-life is 4.5 × [tex]10^5[/tex] years, we can divide the total time ([tex]10^6[/tex] years) by the half-life to find the number of half-lives.

Number of half-lives =[tex]10^6[/tex] years / (4.5 × [tex]10^5[/tex] years)

Therefore, P(x) = R(x) - C(x)800 = 9x - (2.5x + 60)800 = 9x - 2.5x - 60900 = 6.5x = 900 / 6.5x ≈ 138

So, she needs to produce and sell approximately 138 T-shirts to make a profit of $800.

Given Data Joanne sells silk-screened T-shirts at community festivals and craft fairs. Her marginal cost to produce one T-shirt is $2.50.

Her total cost to produce 60 T-shirts is $210, and she sells them for $9 each.
Linear Cost Function

The linear cost function is a function of the form:

C(x) = mx + b, where C(x) is the total cost to produce x items, m is the marginal cost per unit, and b is the fixed cost. Therefore, we have:

marginal cost per unit = $2.50fixed cost, b = ?

total cost to produce 60 T-shirts = $210total revenue obtained by selling a T-shirt = $9

a) To find the value of the fixed cost, we use the given data;

C(x) = mx + b

Total cost to produce 60 T-shirts is given as $210

marginal cost per unit = $2.5

Let b be the fixed cost.

C(60) = 2.5(60) + b$210 = $150 + b$b = $60

Therefore, the linear cost function is:

C(x) = 2.5x + 60b) We can use the break-even point formula to determine the quantity of T-shirts that must be produced and sold to break even.

Break-even point:

Total Revenue = Total Cost

C(x) = mx + b = Total Cost = Total Revenue = R(x)

Let x be the number of T-shirts produced and sold.

Cost to produce x T-shirts = C(x) = 2.5x + 60

Revenue obtained by selling x T-shirts = R(x) = 9x

For break-even, C(x) = R(x)2.5x + 60 = 9x2.5x - 9x = -60-6.5x = -60x = 60/6.5x = 9.23

So, she needs to produce and sell approximately 9 T-shirts to break even. Since the number of T-shirts sold has to be a whole number, she should sell 10 T-shirts to break even.

c) The profit function is given by:

P(x) = R(x) - C(x)Where P(x) is the profit function, R(x) is the revenue function, and C(x) is the cost function.

For a profit of $800,P(x) = 800R(x) = 9x (as given)C(x) = 2.5x + 60

Therefore, P(x) = R(x) - C(x)800

= 9x - (2.5x + 60)800

= 9x - 2.5x - 60900

= 6.5x = 900 / 6.5x ≈ 138

So, she needs to produce and sell approximately 138 T-shirts to make a profit of $800.

Point P lies on the same side of L as A.

Three points A, B and C are not on the same line and are on the same side of the line L. Also, a point P lies in the interior of triangle ABC.

To Prove: Point P is on the same side of L as A.

Proof:

Join the points P and A.

Let's assume for the sake of contradiction that point P is not on the same side of L as A, i.e., they lie on opposite sides of line L. Thus, the line segment PA will intersect the line L at some point. Let the point of intersection be K.

Now, let's draw a line segment between point K and point B. This line segment will intersect the line L at some point, say M.

Therefore, we have formed a triangle PBM which intersects the line L at two different points M and K. Since, L is a line, it must be unique. This contradicts our initial assumption that points A, B, and C were on the same side of L.

Hence, our initial assumption was incorrect and point P must be on the same side of L as A. Therefore, point P lies on the same side of L as A.

The first-order Adams-Moulton formula derived as: y(t+h) ≈ y(t) + h/2 * [f(t, y(t)) + f(t+h, y(t+h))].

The first-order Adams-Moulton formula is equivalent to the trapezoid rule for approximating the integral in ordinary differential equations.

The first-order Adams-Moulton formula is derived by approximating the integral in the ordinary differential equation (ODE) using the trapezoid rule.

To derive the formula, we start with the integral form of the ODE:

∫[t, t+h] y'(t) dt = ∫[t, t+h] f(t, y(t)) dt

Approximating the integral using the trapezoid rule, we have:

h/2 * [f(t, y(t)) + f(t+h, y(t+h))] ≈ ∫[t, t+h] f(t, y(t)) dt

Rearranging the equation, we get:

y(t+h) ≈ y(t) + h/2 * [f(t, y(t)) + f(t+h, y(t+h))]

This is the first-order Adams-Moulton formula.

To verify its equivalence to the trapezoid rule, we can substitute the derivative approximation from the trapezoid rule into the Adams-Moulton formula. Doing so yields:

y(t+h) ≈ y(t) + h/2 * [y'(t) + y'(t+h)]

Since y'(t) = f(t, y(t)), we can replace it in the equation:

y(t+h) ≈ y(t) + h/2 * [f(t, y(t)) + f(t+h, y(t+h))]

This is equivalent to the trapezoid rule for approximating the integral. Therefore, the first-order Adams-Moulton formula is indeed equivalent to the trapezoid rule.

Therefore, the volume generated by rotating the region bounded by the curves [tex]y = 4x - x^2[/tex] and y = x about the y-axis is 27π/2.

(a) To find the volume generated by rotating the region bounded by the curves [tex]y = 4x - x^2[/tex] and y = x about the y-axis, we can use the method of cylindrical shells.

The height of each shell will be given by the difference between the functions [tex]y = 4x - x^2[/tex] and y = x:

[tex]h = (4x - x^2) - x \\ = 4x - x^2 - x \\= 3x - x^2[/tex]

The radius of each shell will be the distance between the curve [tex]y = 4x - x^2[/tex] and the y-axis:

r = x

The differential volume element of each shell is given by dV = 2πrh dx, where dx represents an infinitesimally small width in the x-direction.

To find the limits of integration, we need to determine the x-values where the curves intersect. Setting the two equations equal to each other, we have:

[tex]4x - x^2 = x\\x^2 - 3x = 0\\x(x - 3) = 0[/tex]

This gives us x = 0 and x = 3 as the x-values where the curves intersect.

Therefore, the volume V is given by:

V = ∫[0, 3] 2π[tex](3x - x^2)x dx[/tex]

Integrating this expression will give us the volume generated by rotating the region.

To evaluate the integral, let's simplify the expression:

the formula for T^(-1) is given by:

T^(-1)(a, b) = ((a + 5x2)/3, (b + 3x1)/8)

To show that the given linear transformation T is invertible, we need to demonstrate that it is both injective (one-to-one) and surjective (onto).

1. Injective (One-to-One):

To prove that T is injective, we need to show that if T(x1, x2) = T(y1, y2), then (x1, x2) = (y1, y2).

Let T(x1, x2) = (3x1 - 5x2, -3x1 + 8x2) and T(y1, y2) = (3y1 - 5y2, -3y1 + 8y2).

Setting these two equal, we have:

3x1 - 5x2 = 3y1 - 5y2   ---- (Equation 1)

-3x1 + 8x2 = -3y1 + 8y2 ---- (Equation 2)

From Equation 1, we get:

3x1 - 3y1 = 5x2 - 5y2

3(x1 - y1) = 5(x2 - y2)

Similarly, from Equation 2, we get:

-3(x1 - y1) = 8(x2 - y2)

Since both equations are equal, we can write:

3(x1 - y1) = 5(x2 - y2) = -3(x1 - y1) = 8(x2 - y2)

This implies that x1 - y1 = x2 - y2 = 0, which means x1 = y1 and x2 = y2.

Therefore, T is injective.

2. Surjective (Onto):

To prove that T is surjective, we need to show that for any vector (a, b) in R2, there exists a vector (x1, x2) in R2 such that T(x1, x2) = (a, b).

Let (a, b) be any vector in R2. We need to find (x1, x2) such that T(x1, x2) = (a, b).

Solving the system of equations:

3x1 - 5x2 = a  ---- (Equation 3)

-3x1 + 8x2 = b ---- (Equation 4)

From Equation 3, we can express x1 in terms of x2:

x1 = (a + 5x2)/3

Substituting this value of x1 into Equation 4, we get:

-3((a + 5x2)/3) + 8x2 = b

-3a/3 - 5x2 + 8x2 = b

-3a - 5x2 + 8x2 = b

3x2 = b + 3a

x2 = (b + 3a)/3

Now, we have the values of x1 and x2 in terms of a and b:

x1 = (a + 5x2)/3 = (a + 5(b + 3a)/3)/3

x2 = (b + 3a)/3

Therefore, we have found the vector (x1, x2) such that T(x1, x2) = (a, b), for any (a, b) in R2.

Since T is both injective and surjective, it is invertible.

To find the formula for T^(-1), we can express T(x1, x2) = (a, b) in terms of (

x1, x2):

(3x1 - 5x2, -3x1 + 8x2) = (a, b)

From the first component, we have:

3x1 - 5x2 = a

Solving for x1, we get:

x1 = (a + 5x2)/3

From the second component, we have:

-3x1 + 8x2 = b

Solving for x2, we get:

x2 = (b + 3x1)/8

Therefore, the formula for T^(-1) is given by:

T^(-1)(a, b) = ((a + 5x2)/3, (b + 3x1)/8)

The statement is false. When an economy shrinks at a constant annual rate of 10% for four consecutive years, the cumulative decrease is not 40%.

To calculate the actual decrease over the four-year period, we need to compound the annual decreases. We can use the formula for compound interest:

A = P(1 - r/n)^(nt)

Where:

A = Final amount

P = Initial amount

r = Annual interest rate (as a decimal)

n = Number of compounding periods per year

t = Number of years

In this case, let's assume the initial amount is 100 (representing the size of the economy).

A = 100(1 - 0.10/1)^(1*4)

The radius of convergence of a power series is the distance from its center to the nearest point where the series converges.

To determine the radius of convergence, we can use the Ratio Test.

Step 1: Apply the Ratio Test by taking the limit as n approaches infinity of the absolute value of the ratio of consecutive terms.

Step 2: Simplify the expression and evaluate the limit.

Step 3: If the limit is less than 1, the series converges absolutely, and the radius of convergence is the reciprocal of the limit. If the limit is greater than 1, the series diverges. If the limit is equal to 1, further tests are required to determine convergence or divergence.

The interval of convergence can be found by testing the convergence of the series at the endpoints of the interval obtained from the Ratio Test. If the series converges at one or both endpoints, the interval of convergence includes those endpoints. If the series diverges at one or both endpoints, the interval of convergence does not include those endpoints.

To calculate the probability of a player's height being between 5' 3" and 5' 8" in a normal distribution, we need to standardize the heights using the z-score formula and then use the standard normal distribution table or a calculator to find the probability.

Step 1: Convert the heights to inches for consistency.

5' 3" = 5 * 12 + 3 = 63 inches

5' 8" = 5 * 12 + 8 = 68 inches

Step 2: Calculate the z-scores for the lower and upper bounds using the average height and standard deviation.

Lower bound:

z1 = (63 - 66) / 2 = -1.5

Upper bound:

z2 = (68 - 66) / 2 = 1

Step 3: Use the standard normal distribution table or a calculator to find the area/probability between z1 and z2.

From the standard normal distribution table, the probability of a z-score between -1.5 and 1 is approximately 0.7745.

Therefore, the value of p where the elasticity of demand is unitary is approximately 7.69 dollars.

To determine the value of p where the elasticity of demand is unitary, we need to find the price at which the demand equation has a unitary elasticity.

The elasticity of demand is given by the formula: E = (dp/dx) * (x/p), where E is the elasticity, dp/dx is the derivative of the demand equation with respect to x, and x/p represents the ratio of x to p.

To find the value of p where the elasticity is unitary, we need to set E equal to 1 and solve for p.

Let's differentiate the demand equation with respect to x:
dp/dx = 1/5

Substituting this into the elasticity formula, we get:
1 = (1/5) * (x/p)

Simplifying the equation, we have:
5 = x/p

To solve for p, we can multiply both sides of the equation by p:
5p = x

Now, we can substitute this back into the demand equation:
x + p/5 - 40 = 0

Substituting 5p for x, we have:
5p + p/5 - 40 = 0

Multiplying through by 5 to remove the fraction, we get:
25p + p - 200 = 0

Combining like terms, we have:
26p - 200 = 0

Adding 200 to both sides:
26p = 200

Dividing both sides by 26, we find:
p = 200/26

To solve the initial value problem y' = y(y - 2) with y(0) = y₀, we can separate variables and solve the resulting first-order ordinary differential equation.

Separating variables:

dy / (y(y - 2)) = dt

Integrating both sides:

∫(1 / (y(y - 2))) dy = ∫dt

To integrate the left side, we use partial fractions decomposition. Let's find the partial fraction decomposition:

1 / (y(y - 2)) = A / y + B / (y - 2)

Multiplying both sides by y(y - 2), we have:

1 = A(y - 2) + By

Expanding and simplifying:

1 = Ay - 2A + By

Now we can compare coefficients:

A + B = 0 (coefficient of y)

-2A = 1 (constant term)

From the second equation, we get:

A = -1/2

Substituting A into the first equation, we find:

-1/2 + B = 0

B = 1/2

Therefore, the partial fraction decomposition is:

1 / (y(y - 2)) = -1 / (2y) + 1 / (2(y - 2))

Now we can integrate both sides:

∫(-1 / (2y) + 1 / (2(y - 2))) dy = ∫dt

Using the integral formulas, we get:

(-1/2)ln|y| + (1/2)ln|y - 2| = t + C

Simplifying:

ln|y - 2| / |y| = 2t + C

Taking the exponential of both sides:

|y - 2| / |y| = e^(2t + C)

Since the absolute value can be positive or negative, we consider two cases:

Case 1: y > 0

y - 2 = |y| * e^(2t + C)

y - 2 = y * e^(2t + C)

-2 = y * (e^(2t + C) - 1)

y = -2 / (e^(2t + C) - 1)

Case 2: y < 0

-(y - 2) = |y| * e^(2t + C)

-(y - 2) = -y * e^(2t + C)

2 = y * (e^(2t + C) + 1)

y = 2 / (e^(2t + C) + 1)

These are the general solutions for the initial value problem.

To determine the maximal time interval for the existence of the solution, we need to consider the domain of the logarithmic function involved in the solution.

For Case 1, the solution is y = -2 / (e^(2t + C) - 1). Since the denominator e^(2t + C) - 1 must be positive for y > 0, the maximal time interval for this solution is the interval where the denominator is positive.

For Case 2, the solution is y = 2 / (e^(2t + C) + 1). The denominator e^(2t + C) + 1 is always positive, so the solution exists for all t.

Therefore, for Case 1, the solution exists for the maximal time interval where e^(2t + C) - 1 > 0, which means e^(2t + C) > 1. Since e^x is always positive, this condition is satisfied for all t.

In conclusion, the solution to the initial value problem y' = y(y - 2) with y(0) = y₀ exists for all t.

The following are equivalent for all a,b , (i) implies (ii) and (ii) implies (i), we can conclude that the statements (i) and (ii) are equivalent for all real numbers a and b.

To prove the equivalence of the statements (i) and (ii) for all real numbers a and b, we need to show that (i) implies (ii) and (ii) implies (i).

(i) a < b implies (ii) the average of a and b is greater than a:

Assume a < b. We want to show that the average of a and b is greater than a, i.e., (a + b) / 2 > a.

Multiplying both sides of the inequality a < b by 2, we have 2a < 2b.

Adding a to both sides, we get 2a + a < 2b + a, which simplifies to 3a < a + b.

Dividing both sides by 3, we have (3a) / 3 < (a + b) / 3, resulting in a < (a + b) / 2.

Therefore, (i) implies (ii).

(ii) the average of a and b is greater than a implies (i) a < b:

Assume (a + b) / 2 > a. We want to show that a < b.

Multiplying both sides of the inequality by 2, we have a + b > 2a.

Subtracting a from both sides, we get b > a.

Therefore, (ii) implies (i).

Since we have shown that (i) implies (ii) and (ii) implies (i), we can conclude that the statements (i) and (ii) are equivalent for all real numbers a and b.

In modern computers, data is represented using a binary counting system, which is a base 2 system. This means that it consists of only two digits: 0 and 1.

To convert a binary number to a decimal (base 10) number, you can use the following steps:
1. Start from the rightmost digit of the binary number.
2. Multiply each digit by 2 raised to the power of its position, starting from 0.
3. Add up all the results to get the decimal equivalent.

For example, let's convert the binary number 1011 to decimal:
1. Starting from the rightmost digit, the first digit is 1. Multiply it by 2^0 (which is 1) to get 1.
2. Moving to the left, the second digit is 1. Multiply it by 2^1 (which is 2) to get 2.
3. The third digit is 0, so we don't need to add anything for this digit.
4. Finally, the leftmost digit is 1. Multiply it by 2^3 (which is 8) to get 8.
5. Add up all the results: 1 + 2 + 0 + 8 = 11.
Therefore, the decimal equivalent of the binary number 1011 is 11.

To convert a decimal number to binary, you can use the following steps:
1. Divide the decimal number by 2 repeatedly until the quotient is 0.
2. Keep track of the remainders from each division, starting from the last division.
3. The binary representation is the sequence of the remainders, read from the last remainder to the first.

For example, let's convert the decimal number 14 to binary:
1. Divide 14 by 2 to get a quotient of 7 and a remainder of 0.
2. Divide 7 by 2 to get a quotient of 3 and a remainder of 1.
3. Divide 3 by 2 to get a quotient of 1 and a remainder of 1.
4. Divide 1 by 2 to get a quotient of 0 and a remainder of 1.
5. The remainders in reverse order are 1, 1, 1, and 0. Therefore, the binary representation of 14 is 1110.

Hexadecimal (base 16) is another commonly used number system in computers. It uses 16 digits: 0-9, and A-F. Each digit in a hexadecimal number represents 4 bits (a nibble) in binary.

To convert a binary number to hexadecimal, you can group the binary digits into groups of 4 (starting from the right) and then convert each group to its hexadecimal equivalent.

For example, let's convert the binary number 1010011 to hexadecimal:
1. Group the binary digits into groups of 4 from the right: 0010 1001.
2. Convert each group to its hexadecimal equivalent: 2 9.
3. Therefore, the hexadecimal equivalent of the binary number 1010011 is 29.

To convert a hexadecimal number to binary, you can simply replace each hexadecimal digit with its binary equivalent.

For example, let's convert the hexadecimal number 3D to binary:
1. Replace each hexadecimal digit with its binary equivalent: 3 (0011) D (1101).
2. Therefore, the binary equivalent of the hexadecimal number 3D is 0011 1101.
