Answer:

Step-by-step explanation:

the Laplace transform of the function f(x) = e^(ax) is 1/(a-s).

The definition of the Laplace transform of a function f(t) is given by:

L{f(t)} = F(s) = ∫_0^∞ e^(-st) f(t) dt

where s is a complex number.

If f(x) = 0, then we have:

L{f(x)} = L{0} = ∫_0^∞ e^(-st) 0 dt = 0

Therefore, the Laplace transform of the zero function is zero.

If f(x) = 1, then we have:

L{f(x)} = L{1} = ∫_0^∞ e^(-st) dt

Using integration by parts, we get:

L{1} = ∫_0^∞ e^(-st) dt = [-e^(-st)/s]_0^∞ = [0 - (-1/s)] = 1/s

Therefore, the Laplace transform of the constant function 1 is 1/s.

If f(x) = x, then we have:

L{f(x)} = L{x} = ∫_0^∞ e^(-st) x dt

Using integration by parts again, we get:

L{x} = ∫_0^∞ e^(-st) x dt = [(-e^(-st) x)/s]_0^∞ + (1/s) ∫_0^∞ e^(-st) dt

Since e^(-st) x approaches zero as t approaches infinity, the first term evaluates to zero. We can then simplify the second term using the result from part 2:

L{x} = (1/s) ∫_0^∞ e^(-st) dt = 1/s * (1/s) = 1/s^2

Therefore, the Laplace transform of the function f(x) = x is 1/s^2.

If f(x) = e^(ax), then we have:

L{f(x)} = L{e^(ax)} = ∫_0^∞ e^(-st) e^(ax) dt

Simplifying the integrand, we get:

L{e^(ax)} = ∫_0^∞ e^((a-s)t) dt

We can evaluate this integral using the formula:

∫_0^∞ e^(-bx) dx = 1/b

Setting b = a - s, we get:

L{e^(ax)} = ∫_0^∞ e^((a-s)t) dt = 1/(a-s)

Therefore, the Laplace transform of the function f(x) = e^(ax) is 1/(a-s).

Answer:

The expression (2n)(2n + 1)(4n + 1)/6 - 2n(2n + 1) + 2n is equivalent to ∑i=1 to 2n (i-1)².

Step-by-step explanation:

The expression ∑i=1 to 2n (i-1)² represents the sum of (i-1)² for values of i ranging from 1 to 2n. We can simplify and rewrite this expression using properties of summation:

∑i=1 to 2n (i-1)² = ∑i=1 to 2n (i² - 2i + 1)

= ∑i=1 to 2n i² - ∑i=1 to 2n 2i + ∑i=1 to 2n 1

Now let's evaluate each term separately:

∑i=1 to 2n i²:

This represents the sum of the squares of i for values of i ranging from 1 to 2n. This can be expressed as the formula for the sum of squares:

∑i=1 to 2n i² = (2n)(2n + 1)(4n + 1)/6

∑i=1 to 2n 2i:

This represents the sum of 2i for values of i ranging from 1 to 2n. We can factor out the 2 and use the formula for the sum of the first n positive integers:

∑i=1 to 2n 2i = 2(2n)(2n + 1)/2 = 2n(2n + 1)

∑i=1 to 2n 1:

This represents the sum of 1 for values of i ranging from 1 to 2n. Since we are summing 1 a total of 2n times, this is simply 2n.

Putting it all together, we have:

∑i=1 to 2n (i-1)² = ∑i=1 to 2n i² - ∑i=1 to 2n 2i + ∑i=1 to 2n 1

= (2n)(2n + 1)(4n + 1)/6 - 2n(2n + 1) + 2n

= (2n)(2n + 1)(4n + 1)/6 - 2n(2n + 1) + 2n

Given that:

We have an pyramid with square base.

Area of base of the square pyramid = 169

To find:

Solution:

First of all, let us have a look at the formula of area of a square shape.

Area = side * side

Let the side be equal to  ft.

Putting the given values in the formula:

169 = a^2

so, a = 13 ft

Now, let us have a look at the formula for perimeter of square.

Perimeter of a square shape = 4  Side

Perimeter = 4 * 13 = 52ft

The solution is, 52 ft is the perimeter of the base of the pyramid.

To calculate the probability that a customer at the restaurant buys a burger or fries, we can add the probabilities of buying a burger and buying fries, and then subtract the probability of buying both (to avoid double-counting):

P(burger or fries) = P(burger) + P(fries) - P(burger and fries)

P(burger or fries) = 70% + 55% - 45%

P(burger or fries) = 70% + 55% - 45% = 80%

Therefore, the probability that a customer at the restaurant buys a burger or fries is 80%.

To calculate the probability that a customer at the restaurant buys a burger but does not buy fries, we can subtract the probability of buying both from the probability of buying a burger:

P(burger but not fries) = P(burger) - P(burger and fries)

P(burger but not fries) = 70% - 45%

P(burger but not fries) = 25%

Therefore, the probability that a customer at the restaurant buys a burger but does not buy fries is 25%.

The Economic Order Quantity (EOQ) is calculated to be 547.72 units. The number of orders placed per year is 5.84, and the reorder point (ROP) is 32.01.

The total holding cost of lawnmowers is R1369.30, and the total ordering cost of lawnmowers is R876.00. These calculations provide valuable insights for efficient inventory management.

The Economic Order Quantity (EOQ) can be calculated by using the formula: EOQ = √2DS / H,

where D = Total Demand = 3200 units,

S = Ordering cost per order = R150,

and H = Annual holding cost per unit = R5.

Therefore, EOQ = √ (2 x 3200 x 150) / 5 = 547.72 units.

4.2 Number of orders placed per year: No of orders per year = D / Q,

where D = Total Demand = 3200 units and Q = EOQ = 547.72 units.

Therefore, No of orders per year = D / Q = 3200 / 547.72 = 5.84 orders.

4.4 Total holding cost of lawnmowers:

Total holding cost of lawnmowers = (Average inventory level) x (Annual holding cost per unit),

where (Average inventory level) = EOQ / 2 = 547.72 / 2 = 273.86 units and Annual holding cost per unit = R5.

Thus, the Total holding cost of lawnmowers = 273.86 x R5 = R1369.30.

4.1 Reorder Point (ROP): ROP can be calculated by using the formula:

ROP = dL, where d = Daily demand = D / Number of working days

= 3200 / 300 = 10.67 and L = Lead time = 3 days.

Hence, ROP = dL = 10.67 x 3 = 32.01.

4.5 Total ordering cost of lawnmowers:

Total ordering cost of lawnmowers = (Number of orders placed per year) x (Ordering cost per order),

where (Number of orders placed per year) = 5.84 orders and Ordering cost per order = R150.

Therefore, the Total ordering cost of lawnmowers = 5.84 x R150 = R876.00.

The Economic Order Quantity (EOQ) is calculated to be 547.72 units.

The number of orders placed per year is 5.84, and the reorder point (ROP) is 32.01.

The total holding cost of lawnmowers is R1369.30, and the total ordering cost of lawnmowers is R876.00.
