Answer:

5 km/h

Step-by-step explanation:

Speed of man in still water = s

Speed of current = c

Speed upstream = s - c

Distance upstream = 24 km

Time upstream = 6 hours

Speed downstream = s + c

Distance downstream = 36 km

Time downstream = 6 hours

Speed Equation

speed = distance/time

distance = speed × time

d = st

We write a distance equation for upstream and a second distance equation for downstream.

Upstream:

d = st

24 = (s - c) × 6

Divide both sides by 6 and switch sides:

s - c = 4        Equation 1

Downstream:

d = st

36 = (s + c) × 6

Divide both sides by 6 and switch sides.

s + c = 6       Equation 2

We now have two equations in two variables. We use equations 1 and 2 as a system of equations.

s - c = 4

s + c = 6

Add the equations to use the addition method.

2s = 10

s = 5

Answer:

The perimeter of a rectangle is 30 meters. The length of the rectangles is 3 meters more than twice the width. Find the dimensions of the rectangle.

Step-by-step explanation:

Equation for Perimeter of a rectangle: Perimeter = 2W + 2L

Defining the variables, let

Width = x

Length = 2x+3 (3 more than twice the width)

Plugging everything into the equation

30= 2(x) + 2(2x+3) using the distributive property,

30=2x+4x+6 combining like terms

30=6x+6 subtracting 6 from both sides,

24=6x divide both sides by 6

4=x This means that the width is 4 m

To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for

L=2(4)+3

L=8+3 = 11 m

So the dimensions of the rectangle are width is 4 m and length is 11 m

The characteristic equation are m1 and m2 are  both real and negative, complex conjugates with negative real parts.

1.(a) Given A

\(cos(ωx) + B sin(ωx)\),

we can define E, δ, and µ such that:
\(E = √(A^2 + B^2)\)
\(tan(δ) = A/B\)
\(tan(µ) = -B/A\)
Using these definitions, we can rewrite the original expression as:
\(E sin(ωx - δ) = √(A^2 + B^2) sin(ωx - arctan(A/B))\)
\(F sin(ωx + µ) = √(A^2 + B^2) sin(ωx + arctan(-B/A))\)
(b) The constant E represents the amplitude of the sinusoidal function. The constants δ and µ represent phase shifts in the sine function, affecting where the peaks and troughs occur on the graph of the solution.

Answer:

Natalie bought 500 apples at $0.40 each, then she pays $0.40 500 times, this means that the total cost of the 500 apples is:

Cost = 500*$0.40 = $200

Now she threw away n apples from the 500 apples, then the number of apples that she has now is:

apples = 500 - n

And she sells the remaining apples for $0.70 each.

a) The amount that she gets by selling the apples is:

Revenue = (500 - n)*$0.70

b) We know that she did not make a loss, then the revenue must be larger than the cost, this means that:

cost ≤ revenue

$200 ≤ (500 - n)*$0.70

c) We need to solve the inequality for n.

$200 ≤ (500 - n)*$0.70

$200/$0.70 ≤ (500 - n)

285.7  ≤ 500 - n

n + 285.7 ≤ 500

n ≤ 500 - 285.7

n ≤ 214.3

Then the maximum value of n must be equal or smaller than 214.3

And n is a whole number, then we can conclude that the maximum number of rotten apples can be 214.

Therefore, the compound interest of the annuity due of BD 400 paid each 4 months for 6.2 years at a nominal rate of 3% per annum is BD 40,652.17.

Compound interest of an annuity due can be calculated using the formula:A = R * [(1 + i)ⁿ - 1] / i * (1 + i)

whereA = future value of the annuity dueR = regular paymenti = interest raten = number of payments First, we need to calculate the effective rate of interest per period since the nominal rate is given per annum. The effective rate of interest per period is calculated as

:(1 + i/n)^n - 1 = 3/1003/100 = (1 + i/4)^4 - 1

(1 + i/4)^4 = 1.0075i/4 = (1.0075)^(1/4) - 1i = 0.0303So,

the effective rate of interest per 4 months is 3.03%.Next, we can substitute the given values in the formula:

A = BD 400 * [(1 + 0.0303)^(6.2 * 3) - 1] / 0.0303 * (1 + 0.0303)A = BD 400 * [4.227 - 1] / 0.0303 * 1.0303A = BD 400 * 101.63A = BD 40,652.17

The total area of the figure is composed by the sum of the areas of each part of the figure.

The figure is composed as follows:

Right triangle of sides 2.7 cm and 3 cm.

Right triangle of sides 3.4 cm and 6.8 - 2.7 = 4.1 cm.

The rectangle has of dimensions 5 cm and 2.7 cm.

The area of a right triangle is given by half the multiplication of the sides, hence:

0.5 x 2.7 x 3 = 4.05 cm².

0.5 x 3.4 x 4.1 = 5.61 cm².

The area of a rectangle is given by the multiplication of the dimensions, hence:

5 x 2.7 = 13.5 cm².

Then the total area is given as follows:

13.5 + 6.97 + 4.05 = 24.52 cm².

Hence, the total area of Polygons and Composite Figures is 24.52 cm².

In the given question, it is given that two similar triangles as PQR ~MNO

Then, the corresponding sides will be in equal proportion to each other as follows

PQ / MN = PR / MO = QR / NO

We need to find the length of the side QR

As above relations are given,

\(\frac{PQ}{MN}\) = \(\frac{PR}{MO}\) = \(\frac{QR}{NO}\)

\(\frac{30}{10}\) = \(\frac{5x + 7}{x+5}\) = \(\frac{4x}{\frac{16}{3} }\)

Equating all the fractions, equal to each we'll find

\(\frac{5x + 7}{x+5}\) = \(\frac{30}{10}\)

5x + 7 = 3(x +5)

5x + 7 = 3x + 15

a.  The function for the total expenditures is F(x) = 4.11x² + 87.23x + 1386.52

b.  In 2017, total expenditures will be 3669.57 billion dollars.

a. Since the rate of increase of total expenditures is given as f(x) = 8.22x + 87.23, the function that gives the total expenditures x years after 2000 can be found by integrating the rate of increase:

F(x) = ∫ f(x) dx = 4.11x² + 87.23x + C

Since the total expenditures were $1590.5$ billion in 2002, we can use this information to find the constant $C$:

F(2) = 4.11(2)² + 87.23(2) + C = 1590.5

Solving for C, we get:

C = 1386.52

Therefore, the function that gives the total expenditures x years after 2000 is:

F(x) = 4.11x² + 87.23x + 1386.52 (in billions of dollars)

b. To find the total expenditures in 2017, we need to substitute x = 17 in the function F(x):

F(17) = 4.11(17)² + 87.23(17) + 1386.52≈ 3669.57

Therefore, the total expenditures in 2017 will be approximately 3669.57 billion dollars.

The dimension of the row space of matrix A is 2, the dimension of the column space of A is 4, and the dimension of the null space of A is 3.

To find the dimension of the row space of A, we can count the number of nonzero rows in the echelon form. Since there are two zero rows, the echelon form has 4 - 2 = 2 nonzero rows. Therefore, the dimension of the row space of A is 2.

To find the dimension of the column space of A, we can count the number of pivot columns in the echelon form. Since there are two zero rows, there are at most 5 pivot columns. However, since A is a 4 times 7 matrix, there must be exactly 4 pivot columns. Therefore, the dimension of the column space of A is 4.

To find the dimension of the null space of A, we can use the rank-nullity theorem. The rank of A is the dimension of the column space, which we found to be 4. The nullity of A is the dimension of the null space, which is given by nullity(A) = n - rank(A), where n is the number of columns of A. In this case, n = 7.

Therefore, nullity(A) = 7 - 4 = 3. Therefore, the dimension of the null space of A is 3.

To apply the Economic Order Quantity (EOQ) model with service level, we need to calculate the EOQ and reorder point. Let's go step by step:

Calculate the EOQ (Economic Order Quantity):

EOQ formula: EOQ = sqrt((2 x Annual Demand x Ordering Cost) / Holding Cost per Unit)

Given:

Annual Demand (D) = 12,000 units

Ordering Cost (S) = $50

Holding Cost (H) = 22% of unit cost = 0.22 * $500 = $110

Using the formula:

EOQ = sqrt((2 x12,000 x $50) / $110) = sqrt(1,200,000 / $110) = sqrt(10,909.09) ≈ 104.47

Therefore, the EOQ for the kitchen-table at Smart Home is approximately 104 units.

Calculate the reorder point:

Reorder Point = (Demand per Day * Lead Time) + Safety Stock

Given:

Demand per Day = Daily Demand = 40 units

Lead Time = 3 days

Safety Stock = Z * Standard Deviation of Daily Demand

To calculate the safety stock, we need to determine the value of Z based on the desired service level. Let's assume a standard service level of 95%, which corresponds to a Z-value of 1.645 (for a normal distribution).

Safety Stock = 1.645 * Standard Deviation of Daily Demand

= 1.645 * 18

≈ 29.91

Reorder Point = (40 * 3) + 29.91

= 120 + 29.91

≈ 149.91

Therefore, the reorder point for the kitchen-table at Smart Home is approximately 150 units.

Please note that the calculations provided here assume that the demand and lead time are constant and that there are no stockouts or other factors affecting the inventory. In practice, these assumptions may not hold, and additional considerations may be required for accurate inventory management.
