To complete 4 whole numbers using the fractions 2/3 and 13/7, a total of 31/21 is needed.

To determine how much is needed to complete 4 whole numbers using the fractions 2/3 and 13/7, we need to find the sum of these fractions and subtract it from 4.

First, we need to find a common denominator for the fractions. In this case, the least common multiple (LCM) of 3 and 7 is 21.

We convert the fractions to have the same denominator:

(2/3) x (7/7) = 14/21

(13/7) x (3/3) = 39/21

Now we add the fractions:

14/21 + 39/21 = 53/21

We subtract this sum from 4 whole numbers:

4 - 53/21

To perform this subtraction, we need to have the same denominator:

4 = (4/1) x (21/21) = 84/21

We subtract the fractions:

84/21 - 53/21 = 31/21

Therefore, to complete 4 whole numbers using the fractions 2/3 and 13/7, a total of 31/21 is needed.

The Laplace transform of the given function is,

L{f(t)} = (8/s) - 4e^{-3s/2}/s - 6e^{-2s}/s

Given function is f(t) = {8 12 1 Jo, 0 ≤ t < 3/2, 3/2 ≤ t < 2, 2 ≤ t < ∞ respectively.

We have to find Laplace transform of the given function.

For first interval 0 ≤ t < 3/2,

f(t) = 8u(t) - 8u(t-3/2)

For second interval 3/2 ≤ t < 2,

f(t) = 12u(t-3/2) - 12u(t-2)

For third interval 2 ≤ t < ∞,

f(t) = Jo(u(t-2))

Hence, we can write the Laplace transform of the given function as,

L{f(t)} = L{8u(t) - 8u(t-3/2)} + L{12u(t-3/2) - 12u(t-2)} + L{Jo(u(t-2))}

Where, L is Laplace transform.

Let's calculate each Laplace transform stepwise,

1. L{8u(t) - 8u(t-3/2)}L{8u(t)} = 8/L{u(t)}L{u(t)}

= 1/sL{u(t-3/2)}

= e^{-3s/2}/s

Therefore,

L{8u(t) - 8u(t-3/2)} = 8[1/s - e^{-3s/2}/s]

2. L{12u(t-3/2) - 12u(t-2)}L{12u(t-3/2)}

= 12e^{-3s/2}/sL{12u(t-2)}

= 12e^{-2s}/s

Therefore,

L{12u(t-3/2) - 12u(t-2)} = 12[e^{-3s/2}/s - e^{-2s}/s]

3. L{Jo(u(t-2))}L{Jo(u(t-2))} = ∫_{0}^{∞}δ(t-2)e^{-st}dtL{Jo(u(t-2))}

= e^{-2s}

Hence, the Laplace transform of the given function is,

L{f(t)} = 8[1/s - e^{-3s/2}/s] + 12[e^{-3s/2}/s - e^{-2s}/s] + e^{-2s}

= (8/s) - 4e^{-3s/2}/s - 6e^{-2s}/s

The probability of any one person visiting a particular station is 1/3. Since there are three people in the family, the probability that they would all visit the same station is 1/3 x 1/3 x 1/3, which is equal to 1/27.

The probability that all three members of the family visit the same station at the medical clinic is 1/27 (1/3 x 1/3 x 1/3). This is because each person has an equal chance of being assigned to any of the three stations and since there are three people in the family, the probability that they would all visit the same station is 1/3 multiplied by itself three times, which is equal to 1/27. The experiment is recording the station number for each member and since the incoming individuals are assigned to any of the three stations randomly, the probability that all three members visit the same station is 1/27.

Answer:

x = 3.  y = 11

Step-by-step explanation:

The two equations are two simultaneous equations, which can be solved by substitution, elimination or graphical method.

Elimination method:

The coefficients of 'x’ or ‘y’ need to be the same with opposite signs. The coefficients of ‘y’ will be focused:

                  (17x - y = 40) Multiplied by 4

                  (2x + 4y = 50) Multiplied by 1

                  68x - 4y = 160

                   2x + 4y = 50

In the net total, the ‘y’ terms will cancel each other out:

                 70x = 210

                     x = \(\frac{210}{70}\)

                     x = 3

The calculated value of x is substituted in any of the equations to determine the value of y:

                 17(3) - y = 40

                    51  - y = 40

                   51 - y - 40 = 0

                   51 - 40 - y = 0

                   11 - y = 0

                   y = 11

we can take the reflection over the line perpendicular to side BC passing through point A as the required transformation.

What is triangle?

A triangle is a closed two-dimensional figure with three straight sides and three angles.

1. To sketch the result of dilating triangle ABC using a scale factor of 2 and a center of A, we first draw a segment from point A to a point B' on the other side of side BC such that AB' = 2AC. Similarly, we draw a segment from point A to a point C' on the other side of side AB such that AC' = 2AB. Finally, we draw the triangle AB'C', which is the image of triangle ABC after dilation with a scale factor of 2 and center at point A.

Here is a sketch of triangle AB'C':

2. To sketch the result of dilating triangle ABC using a scale factor of -2 and a center of A, we first draw a line through point A and perpendicular to side BC. Let the intersection of this line with BC be called D. Then, we draw a segment from point A to a point B" on the other side of line AD such that AB" = 2AD. Similarly, we draw a segment from point A to a point C" on the other side of line AD such that AC" = 2AD. Finally, we draw the triangle AB"C", which is the image of triangle ABC after dilation with a scale factor of -2 and center at point A.

3. To find a transformation that would take triangle AB'C' to AB"C", we first note that the dilation with a scale factor of -2 and center at point A is equivalent to a composition of a reflection over the line perpendicular to side BC passing through point A followed by a dilation with a scale factor of 2 and center at point A.

Therefore, we can take the reflection over the line perpendicular to side BC passing through point A as the required transformation.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (5 - 0)/(0 - 4)

Slope (m) = 5/-4

Slope (m) = -5/4

At data point (0, 5) and a slope of -5/4, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 5 = -5/4(x - 0)  

y - 5 = -1.25(x - 0)

y = -5x/4 + 5

y > -5x/4 + 5 (shaded above the dashed line).

At data point (8, -5) and a slope of -5/4, a linear equation for this line can be calculated by using the point-slope form as follows:

Two segments that have the same measure are congruent because congruence means that two figures are identical in shape and size.

Two segments that have the same measure are congruent. In geometry, congruence means that two figures are identical in shape and size. When we say that two segments have the same measure, it means that they have the same length.To understand why two segments with the same measure are congruent, let's consider an example. Suppose we have two line segments, AB and CD, that both have a length of 5 units. By definition, we can say that AB and CD have the same measure.

Now, if we were to superimpose segment AB onto segment CD, we would see that they perfectly overlap each other. This is because they have the same length, or measure. Therefore, we can conclude that segment AB is congruent to segment CD.

This concept applies to any two line segments with the same measure. If two segments have the same length, they are congruent. Conversely, if two segments are congruent, it means they have the same measure. This relationship holds true in geometry, allowing us to determine congruence by comparing segment lengths.In summary, two segments that have the same measure are congruent because congruence means that two figures are identical in shape and size.

The area, in square inches, of a right triangle with a 24-inch leg and a 25-inch hypotenuse is 84 cm.

The area of a right triangle of base b and height h can be calculated using the formula 1/2 × b × h and its perimeter is obtained by just adding all the sides.

Length of one side of the right triangle (p) = 24-inch

Length of the hypotenuse of the right triangle (h) = 25-inch

Therefore, we can calculate the third side (b) of the triangle by applying the Pythagorean theorem

p² + b² = h²

24² + b² = 25²

b² = 625 - 576

b² = 49

b = 7 inch

To show that the series (−1)n − 1bn, where bn = 1 n if n is odd and bn = 1 n2 if n is even, is divergent, we can use the alternating series test.

First, we can note that when n is odd, bn = 1 n, which is a decreasing sequence that approaches 0 as n increases. Therefore, the alternating series (−1)n − 1bn converges by the alternating series test.

However, when n is even, bn = 1 n2, which is also a decreasing sequence that approaches 0 as n increases. But the absolute value of the terms in the series, |(−1)n − 1bn| = |(−1)n − 1(1/n2)|, does not approach 0 as n increases.

To see why, note that when n is even, the term (−1)n is always 1, while the term 1/n2 is always positive. Therefore, the terms in the series alternate in sign and do not decrease in absolute value.

As a result, the series (−1)n − 1bn is not absolutely convergent, and therefore, it is divergent by the alternating series test.

Volume V = x²h

512000 = x²h

h = 512000/x² ..... 1

Surface area =  x² + 2xh + 2xh

Surface area S =  x² + 4xh  ...... 2

Substitute 1 into 2;

From 2;

S =  x² + 4xh

S = x² + 4x(512000/x²)

S = x² + 2048000/x

To minimize the amount of material used;

dS/dx = 0

dS/dx = 2x - 2048000/x²

0 = 2x - 2048000/x²

0 = 2x³ - 2048000

2x³ = 2048000

x³ = 1024000

x = ∛1024000
