The list which orders the numbers from least to greatest is π, √15, 4.1, 4. 85, √30.

To find the list which orders the numbers from smallest to largest we need to find the values of the respective numbers,

In the first list, we have the numbers √13, 2.1, 5.4, √/17, π. The value of √13 = 3.6 and the next term is 2.1. As 2.1 < 3.6, the list does not arrange numbers in increasing order.

In the second list, we have the numbers π, 3.2, 6.3, √17, √20. The value of π is 3.14 and the next terms are 3.2 and 6.3 which are more than the former. But the value of √17 is 4.1 which is less than the previous number 6.3.

In the third list,√23, 2.6, 1.3, √30, π the numbers are not arranged in increasing order as √23's value is 4.8 more than the second number.

In the fourth list, π,√15, 4.1, 4. 85, √30 the numbers are arranged in increasing order when calculated. The value of π is 3.1, of √15 is 3.8, then there are 4.1 and 4.85, and at last, is √30 whose value is 5.5.

Hence, π <√15 < 4.1 < 4. 85 <√30 is the list in the increasing order.

The price in which Evan bought the car for in 2008 is 75 percentage or £14000

What is Percentage ?

Percentage (%), which is a relative figure used to denote hundredths of any quantity. One percent is represented by the symbol 1%; hence, 100 percent denotes the entire amount, and 200 percent designates double the amount.

Given,

Loss% = 25%

Profit% = 45%

selling price = £15,225

The price of the car before getting the profit of 45%

= 15225 / 145 x 100

= 105 x 100

= 10500

The price of the car before getting the profit of 45% is  £10500

Now, he had a loss of 25%

=100% - 25%

= 75%

So, the price will be

= 10500 / 75 x 100

= 14000

Hence, Evan bought the car for £14000 in 2008

If the length of a rectangle is 19 feet longer than the width. If the perimeter is 46 feet, The equation for this scenario where "x" represents the width is 2x + 2 (x +19 ) = 46  and the width is 2 feet.

Given data :

Length of a rectangle = 19 feet

Perimeter = 46 feet

Perimeter formula: 2l+2w=P

Let x represent the width

Hence,

2x + 2 (x +19 ) = 46

2x + 2 x +38 = 46

Collect like terms

4x  = 46 -38

4x = 8

Divide both side by 4x

x = 8/4

x = 2 feet

We have a horizontal translation of 2 units to the right, so the correct option is B.

"The graph of y = f(x) will shift right 2 units."

For any function f(x), a horizontal translation of N units is written as:

g(x) = f(x + N)

if N > 0, the translation is to the left.

if N < 0, the translation is to the right.

In this case we have the function written as:

y = f(x - 2)

So we have N = -2, which means that we have a translation of 2 units to the right.

The solution for inequality  is n < -4.

The given inequality is −2(n − 3.5) > 15

An inequality will have the sign < , > , ≥ or ≤ instead of an equality in an equation. That is, an inequality compares two quantities on either sides of the inequality sign.

We are asked to solve the inequality  −2(n − 3.5) > 15. That is, to find the possible values for n.

−2(n − 3.5) > 15

Dividing throughout by 2,

-(n - 3.5) > 15/2

⇒ -n +3.5 > 7.5

Subtracting 3.5 from both sides,

⇒ -n > 7.5 - 3.5

⇒ -n > 4

Multiply -1 on both sides of the inequality and the inequality will be reversed,

⇒ n < -4 is the solution for n.

The coordinates of the original triangle ABC with vertices is ;

A(-4, 1), B(-1, 1), and C(-1, 3)

For the first reflection along y-axis, the coordinates of y will remain same and x will reverse to positive.

Y-axis reflection: A(4, 1), B(1, 1), and C(1, 3)

Now, the triangle is again reflected along x-axis.

Thus, for the first reflection along x-axis, the coordinates of x will remain same and y will reverse to positive.

x-axis reflection: A(4, -1), B(1, -1), and C(1, -3)

Rotation: The circular motion of an item around a center is referred to as rotation.

The rotation of triangle ABC 180° about the origin.

Rule for Rotation 180° (Clockwise and Counterclockwise);

(x, y)   ----- > (-x, -y)

A(4, -1)  ------> A(-4, 1)

B(1, -1) ------>  B(-1, 1)

C(1, -3) ------>  C(-1, 3)

Rotation 180° = A(-4, 1), B(-1, 1) and C(-1, 3)
