Answer:

You started with $66.

Step-by-step explanation:

The equation would be:

[tex]x-62+50-10=44\\ x-22=44\\ x=66\\[/tex]

To check the answer:

[tex]66-62+50-10=44\\4+50-10=44\\54-10=44\\44=44[/tex]

We started with $66 initially.

Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. It tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.

As per the given data:

Money spend on game (g) = $62

Money received for painting a fence (p) = $50

Money given to friend (f) = $10

Money left = $44

To find out the money we had initially:

Let's assume we had $x.

Money left = x - g + p - f

44 = x - 62 + 50 - 10

44 = x - 22

x = $66

Hence, We started with $66 initially.

Answer:

Answer

Step-by-step explanation:

The function is a greatest integer function, which is a step function.

The function f(x) = 2[x] - 3 features a step-like graph due to the floor function [x]. To graph it, calculate f(x) for integer values, plot the points, and draw horizontal lines between them. The function's range in this context is specified to be between 0 and 20.

The function given is f(x) = 2[x] - 3, where [x] denotes the greatest integer function, also known as the 'floor' function, which returns the greatest integer less than or equal to x. This type of function creates a step-like graph. When graphing this function, you'll notice that for every integer value of x, the function will take on a constant value until the next integer is reached, at which point it will jump up to the next 'step'.

To graph this function, you should first calculate the values of f(x) at various integer points within the given range. Then plot these points on a coordinate plane and create horizontal lines to represent the function's value between each pair of consecutive integer x values. For non-integer values of x, the function value will be based on the floor of x. Label your graph with f(x) and x. Make sure to scale the x and y axes with the maximum values, considering that in this case we are dealing with 0 ≤ x ≤ 20.

Step-by-step explanation:

Final answer:

To factor the quadratic expressions, we look for pairs of numbers that multiply to give the constant term and add to give the coefficient of the middle term, resulting in the expressions (x - 9)(x - 5) for the first and (n + 8)(n - 4) for the second.

Explanation:

The question relates to factoring quadratic expressions, which is a fundamental skill in algebra. Specifically, we are looking to factor the expressions [tex]x^2[/tex] - 14x + 45 and [tex]n^2[/tex] + 4n - 32 completely. Factoring involves finding two binomial expressions that multiply together to give the original quadratic expression.

To factor [tex]x^2[/tex] - 14x + 45, consider two numbers that multiply to 45 and add to -14. These numbers are -9 and -5. Therefore, the factored form is (x - 9)(x - 5).

To factor [tex]n^2[/tex] + 4n - 32, we again look for two numbers that multiply to -32 and add to 4. These numbers are 8 and -4. Thus, the factored form is (n + 8)(n - 4).

Given:

A zip line goes from 28 feet to 11 feet in the air. The angle of depression is 85°.

To find:

The length of the zip line where there is no rider.

Solution:

A right-angled triangle can be formed using the given data.

The difference in height between the start and end of the zipline is [tex]28-11=17[/tex]. The angle of the triangle is 85°.

Assume the zip line is x feet long.

The adjacent side of the triangle measures 17 feet, the hypotenuse of the triangle measures x feet, and the angle of the triangle is 85°.

To determine x, we calculate the cos of the given angle.

[tex]cos \theta = \frac{adjacentside}{hypotenuse} .[/tex]

[tex]cos 85 = \frac{17}{x} , x = \frac{17}{cos85}, cos85= 0.0871.[/tex]

[tex]x = \frac{17}{0.0871} = 195.1779.[/tex]

Rounding this off, we get the length of the zip line when there is no rider is 195.18 feet long.

The length of the zip line when there is no rider is 195.18 feet long.

Here the difference is

= 28 - 11

=17

And, The angle of the triangle is 85°.

Here we Assume the zip line should be x feet long.

Now

The length should be

[tex]cos\ 85 = 17\div x\\\\x = 17\div 0.0871[/tex]

= 195.18

Hence, The length of the zip line when there is no rider is 195.18 feet long.

Answer:

f(16)=162

Step-by-step explanation:

-In a geometric sequence, the quotient between any tow consecutive numbers is called the common ratio,r:

[tex]r=\frac{a_n}{a_{n-1}}[/tex]

Given that f(3)=32 and f(9)=72, we can find the common ratio as below:

[tex]r=\frac{a_n}{a_{n-1}}\\\\\therefore \frac{f(9)}{f(3)}=r^6\\\\\frac{72}{32}=r^6\\\\r^6=2.25\\\\r=2.25^{1/6}[/tex]

#We substitute and use the same formula to find the nth term:

[tex]a_n=ar^{n-1}[/tex]

let f(3) be a(the first term):

[tex]a_n=ar^{n-1}\\\\a_{16}=32(2.25^{1/6})^{16-3-1}\\\\a_{16}=32(2.25^{1/6})^{12}\\\\\\=162[/tex]

Hence, f(16)=162
