By checking the piecewise function and evaluating it at x = 1, the result of the piecewise function is equal to - 4.

Piecewise functions are functions formed by several expressions constrained by intervals in the real set. In this case we find a piecewise functions consisting in two expressions constrained by two intervals in the real set. The piecewise function is defined by these expressions:

Then, we need to evaluate the piecewise function at x = 1. By direct inspection, we conclude that the value according to the piecewise function evaluated at x = 1 is equal to - 4.

Answer:

-20

Step-by-step explanation:

The equation that represents the equal distribution of ' d ' dumplings among Eli and Ana is -

x = nd/2.

Unitary method is used to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Given is a situation in which Eli and Ana are having dinner. They both have same number of dumplings to eat and each dumpling container contains 'd' dumplings.

Let's assume that there are 'n' containers of dumplings and both Eli and Ana got 'x' number of dumplings. Now -

In 1 container we have - 'd' dumplings

In 'n' containers, we will have -  n × d   dumplings.

Both Ana and Eli got same number of dumplings = x.

Therefore -

x + x = n × d

2x = nd

x = nd/2

Therefore, the equation that represents the situation is -

x = nd/2

There may be a maximum of 16 shirts in each row to ensure that all the rows have the same length. Option D

The same elements at play

There are a total of sixteen polo shirts on exhibit.

80 jerseys from various teams are now on exhibit.

Each row is limited to just one kind of polo shirt.

The following are the factors that make up 80:

1, 2, 4, 5, 8, 10, 16, 20, and 80

The factors of 16 are as follows: 1, 2, 4, 8, 16.

The number 16 is the most frequent factor between the numbers 80 and 16.

Therefore, the greatest number of shirts that may be placed in each row such that the length of all of the rows is the same is 16.

Answer:

196m²

Step-by-step explanation:

area is w multiplied by h so 14x14

Answer:

196 [tex]m^{2}[/tex]

Step-by-step explanation:

The area of a rectangle is length times width.  A square is a type of rectangle that has four equal sides, so if we know one side we know all four.

A = l x w

A = 14m x 14m

A = 196[tex]m^{2}[/tex]

5. m∠ABC = 64°

m∠CBD = 26°

6. Using the linear pair postulate,

m∠ABC = 97°

m∠CBD = 83°

7. Using the linear pair postulate,

m∠ABC = 112.5°

m∠CBD = 67.5°

Two angles on a straight line form a linear pair which have a sum of 180 degrees based on the linear pair postulate.

5. (11x - 2) + (5x - 4) = 90 [complementary angles]

11x - 2 + 5x - 4 = 90

16x - 6 = 90

16x = 90 + 6

16x = 96

x = 6

m∠ABC = 11x - 2 = 11(6) - 2 = 64°

m∠CBD = 5x - 4 = 5(6) - 4 = 26°

6. 8x + 9 + 6x + 17 = 180 [linear pair postulate]

14x + 26 = 180

14x = 180 - 26

14x = 154

x = 11

m∠ABC = 8x + 9 = 8(11) + 9 = 97°

m∠CBD = 6x + 17 = 6(11) + 17 = 83°

7. 14x - 6.5 + 7x + 8 = 180 [linear pair postulate]

21x + 1.5 = 180

21x = 180 - 1.5

21x = 178.5

x = 8.5

m∠ABC = 14x - 6.5 = 14(8.5) - 6.5 = 112.5°

m∠CBD = 7x + 8 = 7(8.5) + 8 = 67.5°

The general formula that describes the variation is T² = 18a³/d²

          x ∝ y.

          This can then be written as;

           x = ky

           Where;

           k = constant rate of change.

            x ∝ (y/z)

           This can then be written as;

            x = k (y/z)

           Where;

           k = constant rate or variation

The square of T varies directly with the cube of a and inversely with the square of d.

Note that

square of T = T²

cube of a = a³

square of d = d²

Therefore, we can write;

T² ∝ a³/d²

T² = k (a³/d²)

Since;

T = 4 when a = 2 and d = 3

We can find the constant of proportionality k, by substituting the values of T=4, a = 2 and d = 3 into equation (i) and solve as follows;

(4)² =  k (2³/3²)

16 =  k (8/9)

8k = 16 x 9

8k = 144

k = 144/8

k = 18

Therefore, The overall formula for describing the variation is

T² =  18 a³/d²

The answer you will be looking for is 145638!

If you need help how to i will explain!

The Initial amount is 14.76 and the decay factor is 1.4 while the percentage rate of change is 40%.

We are given the function as;

y = 1.4^(t + 8)

Now, the general formula for an exponential decay function is;

f(x) = abˣ

where;

a = initial amount

b = decay factor

x = number of time intervals

Now, using laws of exponents, our initial function can be written as;

y = 1.4⁸ × 1.4^(t)

Now, 1.4⁸ = 14.76

Thus, we now have the expression as;

y = 14.76(1.4^(t))

Comparing with the general equation of exponential decay gives us;

14.76 = initial amount

1.4 = decay factor

t = number of time intervals

If decay factor is 1.4, then this denotes 140% which means that the percentage rate of change is 40%

The above statement describes the equation of a circle whose endpoints of a diameter are (-0,0) and (4,-6):

(x + 2)² + (y + 3)² = 3.6

The simple form equation of a circle is: (x – x1)² + (y – y1)²= r², where (x, y) are arbitrary coordinates upon that circumference of the circle, r seems to be the radius of the circle. and (x1, y1) are indeed the coordinates of the circle's center.

Given points are:

(-0,0) and (4,-6)

Find that diameter's length using the locations of the locations as well as the distance formula.

d = √((x₂ - x₁)² + (y₂ - y₁)²)

  = √((4 - (-0))² + (-6 - 0)²)

 = √((4 )² + (-6 )²)

= √(16 + 36)

= √(52)

= 7.2

Radius will be r/2

7.2/2

= 3.6

To obtain the coordinates of the center, use the interest in obtaining and the midpoint formula.

[tex]C=\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}[/tex]

C = (-0 + 4)/2 , (-6 + 0)/2

C = -2 , -3

To write this circle equation, use the radius and the center coordinates.

(x - h)² + (y - h)² = r²

(x - (-2))² + (y - (-3))² = 3.6

(x + 2)² + (y + 3)² = 3.6
