The rectangular tank initially filled with water measures 28 cm by 18 cm by 12 cm. After draining 0.78 liters of water from the tank, there is 5,268 milliliters (or 5.268 liters) of water left in the tank.

To determine the amount of water left in the tank, we need to calculate the initial volume of water in the tank and subtract the volume of water drained. The volume of a rectangular tank is given by the formula: length × width × height.

The initial volume of water in the tank is calculated as follows:

Volume = 28 cm × 18 cm × 12 cm = 6,048 cm³.Since 1 liter is equal to 1,000 cm³, the initial volume can be converted to liters:

Initial volume = 6,048 cm³ ÷ 1,000 = 6.048 liters.

Next, we subtract the drained volume of 0.78 liters from the initial volume to find the remaining amount:

Remaining volume = Initial volume - Drained volume = 6.048 liters - 0.78 liters = 5.268 liters.

To convert the remaining volume to milliliters, we multiply it by 1,000:

Remaining volume in milliliters = 5.268 liters × 1,000 = 5,268 milliliters.

Therefore, after draining 0.78 liters of water from the tank, there is 5,268 milliliters (or 5.268 liters) of water left in the tank.

The profit that will be made if the cost for making each vetkoek is R4.00 and the costs of all ingredients is R623.48 per week is R2 720.00. Therefore, the profit is R2 720.00.

Profit is the excess of revenue over cost. The learners in the above problem are selling 340 vetkoeks per week for 15 weeks at R12.00 each vetkoek.

We want to calculate the profit that they will make assuming the cost of making each vetkoek is R4.00 and the costs of all ingredients is R623.48 per week.

Here is the breakdown of the calculations;

Cost of making each vetkoek

= R4.00Cost of all ingredients per week

= R623.48Number of vetkoeks sold per week

= 340Selling price of each vetkoek

= R12.00 per vetkoek Revenue generated per week

= Selling price per vetkoek × Number of vetkoeks sold per week= R12.00/vetkoek × 340 vetkoeks

= R4 080.00 per week.

Cost of producing each vetkoek

= R4.00Profit generated per vetkoek

= Selling price of each vetkoek − Cost of producing each vetkoek= R12.00/vetkoek − R4.00/vetkoek

= R8.00/vetkoek.

Profit generated per week

= Profit generated per vetkoek × Number of vetkoeks sold per week= R8.00/vetkoek × 340 vetkoeks

= R2 720.00 per week.

The profit that will be made if the cost for making each vetkoek is R4.00 and the costs of all ingredients is R623.48 per week is R2 720.00. Therefore, the profit is R2 720.00.

(a) The probability of drawing only odd numbered balls is 1/8 or 0.125.

(b) The probability of the smallest drawn number being equal to k for k = 1,...,10 is (4 choose 1)/ (10 choose 4) or 0.341.

(a) To calculate the probability of only drawing odd numbered balls, we first need to find the total number of ways to draw four balls from the urn, which is (10 choose 4) = 210. Then, we need to find the number of ways to draw only odd numbered balls, which is (5 choose 4) = 5. Thus, the probability of only drawing odd numbered balls is 5/210 or 1/8.

(b) To calculate the probability that the smallest drawn number is equal to k for k = 1,...,10, we first need to find the total number of ways to draw four balls from the urn, which is (10 choose 4) = 210. Then, we need to find the number of ways to draw four balls such that the smallest drawn number is k. We can do this by choosing one ball from the k available balls (since we need to include that ball in our draw to ensure the smallest drawn number is k) and then choosing three balls from the remaining 10-k balls. Thus, the number of ways to draw four balls such that the smallest drawn number is k is (10-k choose 3). Therefore, the probability that the smallest drawn number is equal to k is [(10-k choose 3)/(10 choose 4)] for k = 1,...,10, which simplifies to (4 choose 1)/(10 choose 4) = 0.341.

Leila served 30 orders, Keith served 36 orders, and Michael served 21 orders.

Let's assume the number of orders served by Michael is M. According to the given information, Keith served 3 times as many orders as Michael, so Keith served 3M orders. Leila served 7 more orders than Michael, which means Leila served M + 7 orders.

The total number of orders served by all three individuals is 87. We can set up the equation: M + 3M + (M + 7) = 87.

Combining like terms, we simplify the equation to 5M + 7 = 87.

Subtracting 7 from both sides, we get 5M = 80.

Dividing both sides by 5, we find M = 16.

The flow along the given curve r(t) in the direction of increasing t is -1/4.

To find the flow along the given curve r(t) = ti +[tex]t^{2}[/tex]j + k, 0 ≤ t ≤ 1 in the direction of increasing t, we need to calculate the line integral of the velocity field f = -3xyi + 2yj + 5k over this curve.

The line integral of f over the curve r(t) is given by:

∫f · dr = ∫(-3xyi + 2yj + 5k) · (dx/dt)i + (2t)j + (dz/dt)k dt

= ∫(-3xy(dx/dt) + 2yt + 5(dz/dt)) dt

Now, we need to substitute the components of the curve r(t) into this expression:

x = t

y =[tex]t^{2}[/tex]

z = 1

And, we need to calculate the derivatives with respect to t:

dx/dt = 1

dy/dt = 2t

dz/dt = 0

Substituting these values, we get:

∫f · dr = ∫(-3[tex]t^{3}[/tex](1) + 2t([tex]t^{2}[/tex]) + 5(0)) dt

= ∫(-3[tex]t^{3}[/tex] + 2[tex]t^{3}[/tex] ) dt

The flow along the given curve r(t) = ti + t^2j + k, 0 ≤ t ≤ 1, in the direction of increasing t is 1/4.

For finding the flow along the curve r(t) = ti + t^2j + k, 0 ≤ t ≤ 1, in the direction of increasing t, we need to evaluate the dot product of the velocity field F = -3xyi + 2yj + 5k with the tangent vector of the curve.

The tangent vector of the curve r(t) is given by dr/dt, which is the derivative of r(t) with respect to t:

dr/dt = i + 2tj

Now, let's calculate the dot product:

F · (dr/dt) = (-3xyi + 2yj + 5k) · (i + 2tj)

To calculate the dot product, we multiply the corresponding components and sum them up:

F · (dr/dt) = (-3xy)(1) + (2y)(2t) + (5)(0)

Since the third component of F is 5k and the third component of dr/dt is 0, their dot product is 0.

Now, let's simplify the first two terms:

F · (dr/dt) = -3xy + 4yt

To find the flow along the given curve, we need to integrate this dot product over the interval 0 ≤ t ≤ 1:

Flow = ∫[0,1] (-3xy + 4yt) dt

To evaluate this integral, we need to express x and y in terms of t using the parameterization r(t) = ti + t^2j + k:

x = t

y = t^2

Substituting these values into the integral, we have:

Flow = ∫[0,1] (-3t(t^2) + 4t(t^2)) dt

    = ∫[0,1] (t^3) dt

Evaluating this integral, we get:

Flow = [t^4/4] evaluated from 0 to 1

    = (1^4/4) - (0^4/4)

    = 1/4

Therefore, the flow along the given curve r(t) = ti + t^2j + k, 0 ≤ t ≤ 1, in the direction of increasing t is 1/4.

The value of the iterated integral is 16/3.

To calculate the iterated integral ∫∫R (x + y)^2 dx dy, where R is the region bounded by x = 0, x = 1, y = 0, and y = 2, we can first integrate with respect to x and then with respect to y.

∫∫R (x + y)^2 dx dy

= ∫[0,2] ∫[0,1] (x + y)^2 dx dy

Let's begin by integrating with respect to x:

∫[0,1] (x + y)^2 dx

= [ (1/3)(x + y)^3 ] evaluated from x = 0 to x = 1

= (1/3)(1 + y)^3 - (1/3)(0 + y)^3

= (1/3)(1 + y)^3 - (1/3)y^3

Now, we can integrate this expression with respect to y:

∫[0,2] [(1/3)(1 + y)^3 - (1/3)y^3] dy

= (1/3) ∫[0,2] (1 + y)^3 dy - (1/3) ∫[0,2] y^3 dy

For the first integral, we can use the power rule for integration:

(1/3) ∫[0,2] (1 + y)^3 dy

= (1/3) [ (1/4)(1 + y)^4 ] evaluated from y = 0 to y = 2

= (1/3) [ (1/4)(1 + 2)^4 - (1/4)(1 + 0)^4 ]

= (1/3) [ (1/4)(3^4) - (1/4)(1^4) ]

= (1/3) [ (1/4)(81) - (1/4) ]

= (1/3) [ 81/4 - 1/4 ]

= (1/3) (80/4)

= (1/3) (20)

= 20/3

For the second integral, we can also use the power rule for integration:

(1/3) ∫[0,2] y^3 dy

= (1/3) [ (1/4)y^4 ] evaluated from y = 0 to y = 2

= (1/3) [ (1/4)(2^4) - (1/4)(0^4) ]

= (1/3) [ (1/4)(16) - (1/4)(0) ]

= (1/3) (16/4)

= (1/3) (4)

= 4/3

Combining the results:

∫∫R (x + y)^2 dx dy

= (20/3) - (4/3)

The position vector of the particle is r(t) = (1/2)t^2 i + (e^t -1) j + (1-e^-t) k + j + k.

Given: a(t) = ti + e^tj + e^-tk, v(0) = k, r(0) = j+k.

Integrating the acceleration function, we get the velocity function:

v(t) = ∫ a(t) dt = (1/2)t^2 i + e^t j - e^-t k + C1

Using the initial velocity, v(0) = k, we can find the constant C1:

v(0) = C1 + k = k

C1 = 0

So, the velocity function is:

v(t) = (1/2)t^2 i + e^t j - e^-t k

Integrating the velocity function, we get the position function:

r(t) = ∫ v(t) dt = (1/6)t^3 i + e^t j + e^-t k + C2

Using the initial position, r(0) = j+k, we can find the constant C2:

r(0) = C2 + j + k = j + k

The greatest vertical length of the green section should be approximately 3.52 feet.

To determine the greatest vertical length of the green section, we can use the given information that the greatest horizontal length of the green section is 8.8 feet.

Since the ratio of the line segment is 5:2, we can set up a proportion using the horizontal and vertical lengths of the green section:

(horizontal length of green section) / (vertical length of green section) = (5/2)

Let's denote the greatest vertical length of the green section as y. We can rewrite the proportion as:

8.8 / y = 5 / 2

To solve for y, we can cross-multiply and then divide:

8.8 * 2 = 5 * y

17.6 = 5y

Dividing both sides by 5, we get:

y = 17.6 / 5

y ≈ 3.52 feet

Therefore, the greatest vertical length of the green section should be approximately 3.52 feet.

It's important to note that this calculation assumes a linear relationship between the horizontal and vertical lengths of the green section. If there are other factors or constraints involved in the scenario, such as angles or specific geometric properties, a more detailed analysis may be required to determine the exact vertical length.

If the interest is tax-exempt income, Y's annual net cash flow from the investment can be calculated as follows:

Annual interest income = $65,000 × 8% = $5,200

Since the interest income is tax-exempt, Y does not have to pay taxes on it. Therefore, Y's annual net cash flow from this investment is equal to the annual interest income: $5,200.

b. If the interest is taxable income then annual net cash flow will be  $3,640.

If the interest is taxable income, Y's annual net cash flow from the investment needs to account for the taxes owed on the interest income. The tax owed can be calculated as follows:

Tax owed = Annual interest income × Marginal tax rate

Tax owed = $5,200 × 30% = $1,560

Subtracting the tax owed from the annual interest income gives us the annual net cash flow:

Annual net cash flow = Annual interest income - Tax owed

Annual net cash flow = $5,200 - $1,560 = $3,640

2. Apply the distance formula: d = √[(x2 - x1)^2 + (y2 - y1)^2]
3. Substitute the coordinates into the formula: d = √[(-14 - (-2))^2 + (-10 - (-5))^2]
4. Simplify the equation: d = √[(-12)^2 + (-5)^2]
5. Calculate the squared values: d = √[(144) + (25)]
6. Add the squared values: d = √(169)
7. Calculate the square root: d = 13

So, The distance between the points (-2, -5) and (-14, -10) is 13 units.

The probability that a player receives an even number of points or more than 10 points is 0.35 or 35%.

To find the probability that a player receives an even number of points or more than 10 points, we can use the principle of inclusion-exclusion.

Let's define:

A = Event of receiving an even number of points

B = Event of receiving more than 10 points

We are given the following probabilities:

P(A) = 23/100

P(B) = 12/100

P(A ∩ B) = 14/100

The formula for the probability of the union of two events is:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Substituting the given values:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

= 23/100 + 12/100 - 14/100

= 35/100

= 0.35

Therefore, the probability that a player receives an even number of points or more than 10 points is 0.35 or 35%.

The length of the third side of a right triangle with legs of lengths 3 and 5 is √34, and the length of either leg is 3.

Let's say that the two legs of a right triangle have the lengths a and b, and the length of the hypotenuse is c.

The Pythagorean Theorem states that

a² + b² = c².

If the legs or the hypotenuse are not whole numbers, the answer must be given in the form of an expression using the symbol (i.e., it is a surd).

Let's take an example of a triangle having legs of lengths 3 and 5:

For a right triangle with legs of lengths 3 and 5, the square of the hypotenuse can be determined using the Pythagorean Theorem:

a² + b² = c²

3² + 5² = c²

9 + 25 = c²

34 = c²

c = √34

The length of the hypotenuse is equal to √34, which is not a whole number.

If we were asked to find the length of one of the legs, we could rearrange the Pythagorean Theorem to solve for a or b.

For example, to solve for a, we could rewrite the equation as:

a² = c² - b²

a² = (√34)² - 5²

a² = 34 - 25

a² = 9

a = √9

a = 3

Therefore, the length of the third side of a right triangle with legs of lengths 3 and 5 is √34, and the length of either leg is 3.

The sum of the arithmetic sequence 4, 11, 18, 25, ..., 249 is 4554 and there are 36 terms in the sequence.

(a) To determine the number of terms in the sum, we can find the pattern in the terms.  we observe that each term is obtained by adding 7 to the previous term. Starting from 4 and incrementing by 7, we can write the sequence of terms as 4, 11, 18, 25, ..., and so on.

To find the number of terms, we need to determine the value of n in the equation 4 + 7(n-1) = 249. Solving this equation, we find n = 36. There are 36 terms in the sum.

(b) To compute the sum using a technique discussed in this section, we can use the formula for the sum of an arithmetic series. The formula is given by Sn = (n/2)(2a + (n-1)d), where Sn represents the sum of the series, n is the number of terms, a is the first term, and d is the common difference.

In this case, the first term a is 4, the number of terms n is 36, and the common difference d is 7.
