The coordinates of the image of point B of quadrilateral ABCD after the translation of 5 units to the left and 3 units down are B'(-14, -11).

In Mathematics, the translation of a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image.

On the other hand, the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate of the pre-image.

By translating the pre-image of quadrilateral ABCD vertically down by 3 units and horizontally left by 5 units, the coordinates of B in triangle A'B'C' include the following:

(x, y)                               →                  (x - 5, y - 3)

Coordinate B = (-9, -8)   →    Coordinate B' = (-9 - 5, -8 - 3) = (-14, -11)

If everyone shakes hands with everyone else in a group of 20, the number of handshakes take place is 210.

In a group of 20 people, if everyone shakes hands with everyone else, the number of handshakes that take place is equal to the sum of the first 20 positive integers, which can be found using the formula for the sum of an arithmetic series:

= n (n + 1)/ 2

= (20 * 21) / 2 = 210

To understand why this is the case, consider that each person shakes hands with 19 other people, so there are a total of 20 * 19 = 380 handshakes. However, each handshake is counted twice (once for each person involved), so we need to divide the total number of handshakes by 2 to get the actual number of unique handshakes. Hence, the answer is 380 / 2 = 210.

Answer:

  Sn = (7 -(6n +7)3^-n)/4

Step-by-step explanation:

You want the sum of n terms of the series 2/3 +5/9 +8/27 +11/81 +....

The sums of n terms for n = 1 .. 5 are ...

  2/3, 11/9, 41/27, 134/81, 416/243

We recognize the denominators as powers of 3. The numerator sequence is ...

  2, 11, 41, 134, 416, ...

Differences are ...

  9, 30, 93, 282

And second differences are ...

  21, 63, 189

We note that these have a common ratio of 3, leading us to speculate that the numerator sequence can be written as the sum of a linear expression and a power of 3.

Assuming the sequence of numerator terms is of the form ...

  a·3^n +bn +c

We can write equations for a, b, c:

  a·3 +b·1 +c = 2 . . . . . . for n = 1

  a·9 +b·2 +c = 11 . . . . . .for n = 2

  a·27 +b·3 +c = 41 . . . . for n = 3

These equations can be solved for a, b, c using any of your favorite techniques. The attached calculator output shows the values to be ...

  a = 1.75 = 7/4

  b = -1.5 = -6/4

  c = -1.75 = -7/4

Then the sum of n terms can be written as ...

  [tex]\boxed{S_n=\dfrac{7\cdot3^n -6n-7}{4\cdot3^n}}[/tex]

Additional comment

The n-th term of the series is (3n-1)/3^n. This can be decomposed into two sums: 3(n/3^n) -1/3^n. The latter is the well-known sum of a geometric series. The sum of the first term is less well-known: ∑(k/3^k) = (3(3^n-1)-2n)/(4·3^n).

The general solution of the differential equation is [tex]y = \frac{\pm Ce^{3e^{-x}} + 1}{x}[/tex], where C is an arbitrary constant.

To find the general solution, we can first try separating the variables by dividing both sides of the equation by x²:

The given differential equation is (x²)dy/dx + (x²)y = [tex]6xe^{-x[/tex]

[tex]\frac{dy}{y} = 6e^{-x} \frac{dx}{x^2}[/tex]

Integrating both sides with respect to their respective variables:

[tex]\int (dy/y) = \int 6e^{-x} \frac {dx}{x^2} + C[/tex]

ln [tex]|y| = \frac{-3e^{-x} - 1}{x} + C[/tex]

Exponentiating both sides:

[tex]|y| = \frac{Ce^{3e^{-x}} - 1}{x}[/tex]

where C is an arbitrary constant.

Since the solution for y is not unique, we need to determine the sign of y. To do this, we can analyze the initial conditions or the nature of the problem. If the initial conditions indicate that y is positive, then [tex]y = \frac{\pm Ce^{3e^{-x}} + 1}{x}[/tex]. If the initial conditions indicate that y is negative, then [tex]y = \frac{\pm Ce^{3e^{-x}} + 1}{x}[/tex].

Therefore, the general solution of the differential equation is [tex]y = \frac{\pm Ce^{3e^{-x}} + 1}{x}[/tex], where C is an arbitrary constant.

where n is the total number of elements in the set and k is the number of elements to be selected.

C(40,3) = 40! / [3!(40 - 3)!] = 9880

The number of ways to select 1 Democrat, 1 Republican and 1 Independent is as follows:

The number of children is 379 and the number of the adults is 339.

A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A collection of equations fulfilled by the same set of variables is called a system of linear equations."

Let us suppose the number of children = C, and the number of adults = A.

Given that, 718 people used the public swimming pool:

C + A = 718 people

The cost for one child is 1.25 for children, then the cost for C child is: 1.25C

The cost for one adult is 2.00 for adults, then the cost for A adults is: 2A

The receipts for admission totaled 1151.75:

1.25C + 2A = 1151.75

The two equations are:

C + A = 718

1.25C + 2A = 1151.75

For the first equation we can write:

C + A = 718

C = 718 - A

Substitute the value of C in second equation:

1.25(718 - A) + 2A = 1151.75

897.5 - 1.25A + 2A = 1151.75

0.75A = 254.25

A = 339

Substituting the value of A in the first equation we have:

C + A = 718

C + 339 = 718

C = 379

Hence, the number of children is 379 and the number of the adults is 339.

A) The best way to estimate average speed is to make sure that each number is a whole number (with no decimals). This will make division much easier. The number of meters is already a whole number, but to make the number of minutes a whole number, we must round. Because the number after the decimal is greater than 5, that means we will round up, making the value of minutes 5. Now we can estimate 1500 metres/5 minutes = 300 metres/minute

As a little rounding tip, you can use this mnemonic: 4 and below, let it go (round down). 5 and above, give it a shove (round up)!

B) To do this part, we can simply plug the following into the calculator:
