What is meant by indices?Indices, also known as exponents or powers, are mathematical symbols that express the repeated multiplication of a number. These numbers show how many times the base number has been multiplied by itself. For example, the index of 2 in the formula 23 is 3, which indicates that 2 is multiplied by itself three times to provide the value 8. Indices are often written as little numbers to the right and above the base number, with the latter enclosed in parentheses or brackets. Indices are often used to indicate the size or quantity of a number in mathematical model, but they may also be used to represent the degree of a polynomial function or the order of a derivative in calculus.
How to solve?
To print the integer at index 2 of the values list, we can use the following code: print(values[2])
To print the integer at index -2 of the values list, we can use the following code: print(values[-2])
Here, the index -2 refers to the second-to-last element in the list, which is the integer 19.
Therefore, the final code would be:
values = [ 14, 10, 8, 19, 7.13]
print(values[2], values[-2])
This code would print the following output:

How many miles do they have to drive before lena and peter pay the same price for the rental for the same number of miles?.
They have to drive 200 miles before Lena and Peter pay the same price for the rental .
In the question ,
it is given that ,
let x be the number of miles they drive together and pay the same amount.
the charge for Lena's car rental company is $50 per day and then $0.40 per miles which is represented by the equation
Cost = 50 + 0.40x
the charge for Peter's car rental company is $70 per day and then $0.30 per miles which is represented by the equation
Cost = 70 + 0.30x
Equating the cost for Lena and Peter car rental company
70 + 0.30x = 50 + 0.40x
0.40x - 0.30x = 70 - 50
0.10x = 20

Answer:

Step-by-step explanation:
The corresponding angles theorem shows that -6x+80 is supplementary to 25.
So -6x+80+25=180
-6x+80=155
-6x=75
-6x/-6=75/-6
x=-12.5

Not exactly sure what this is but by a glance theyre asking what do you do to days to get the total?
Therefore if you have in the D column 1-5 the process is always multiplying by 250 so 1 day gives 1 * 250 = $250
2 days gives 2*250 = $500

Solve the following equation: 45-3x=18
I tried x=9 but it said it was wrong
Answer: x = [tex]\frac{15}{7}[/tex]
Step-by-step explanation:
To solve, we will isolate the variable by using reverse operations. You commented the proper equation is 45 - 3x = 18x
Given:
45 - 3x = 18x
Add 3x to both sides of the equation:
45 = 21x
Divide both sides of the equation by 21:

Which function (with domain all integers n

The following number in the series is 48.
Arithmetic Progression (AP) is a number sequence in which the difference between any two consecutive numbers is a constant value.
Given first five terms of a sequence are 3,8, 15, 24, 35
On examining the series we see:
3 - 0 = 3
8 - 3 = 5
15 - 8 = 7
24 - 15 = 9
35 - 24 = 11
The increments are an arithmetic progression with the first term being 3 and the difference being 2.
The next term (sixth term) is 13.
Hence the next number of the series 3, 8, 15, 24, and 35 is 35 + 13 = 48

(8x² + 8x - 9) + (3x² + 5x) = 0.
∴ (8x² + 8x - 9) + (3x² + 5x) = 0
=> 8x² + 8x - 9 + 3x² + 5x = 0

After obtaining the standard form a, b and c are identified from the original equation and are placed into the quadratic formula.
∴ x = (-b±√(b²-4ac))/(2a)
11x² + 13x -9 = 0
where,
a = 11, b = 13, c = -9
=> x = (-13 ± √(13² - 4×11(-9)) )/ (2×11)
