What is the solution to the inequality 5.25- b
6.5?

Answer:

r = 6

Step-by-step explanation:

1 - r = -5

Subtract 1 on both sides

-r = -5 -1

-r = -6

Divide by -1 on both sides

r = 6

Answer:

The distance between them after 1 hour and 30 minutes will be of 63.64 miles.

Step-by-step explanation:

This question can be solved using the Pythagorean Theorem.

Both cars travel at a constant speed of 30 miles per hour. So, after 1 hour and 30 minutes, which is 1 and a half hour, they will have traveled 30*1.5 = 45 miles.

The distance between them is the hypotenuse of a right triangle, in which the sides are 45. So

[tex]d^2 = 45^2 + 45^2[/tex]

[tex]d = \sqrt{45^2 + 45^2}[/tex]

[tex]d = 63.64[/tex]

The distance between them after 1 hour and 30 minutes will be of 63.64 miles.

Answer:

114°

Step-by-step explanation:

First we have to calculate the value of c Then

3c - 84° + c = 180° <being co-interior angles >

4c - 84° = 180°

4c = 180° + 84

4c = 264°

c = 264° / 4

c = 66°

Now

<R = 3 * 66° - 84°

= 114°

<P = <R ( being opposite angles of rhombus )

<P = 114°

Hope it will help :)

Answer:

x = -123/14

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

250 = 4(1 - 7x)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 250 does indeed equal 250.

∴ x = -123/14 is the solution to the equation.

Answer:

The exponential model for the population is [tex]P(t) = 19000e^{0.048t}[/tex]

Step-by-step explanation:

The exponential model for the population has the following format:

[tex]P(t) = P(0)e^{rt}[/tex]

In which P(0) is the initial population and r is the growth rate, as a decimal.

A population numbers 19,000 organisms initially and grows by 4.8% each year.

This means that [tex]P(0) = 19000, r = 0.048[/tex]

So

[tex]P(t) = P(0)e^{rt}[/tex]

[tex]P(t) = 19000e^{0.048t}[/tex]

The exponential model for the population is [tex]P(t) = 19000e^{0.048t}[/tex]

The second option (5n)

["Product" is for multiplication]

Answer:

Step-by-step explanation:

Points to remember while solving a system of linear equations,

1). If the equations have same slope, solution of the system will have no solution.

2). If both the equations are same, system will have infinitely many solutions.

3). If both the equations have different coefficients of variables, system of equations will have exactly one solution.

Question 11,

ax + 4y = 10 ------ (1)

-9x - 6y = -15

-3x - 2y = -5

-6x - 4y = -10

6x + 4y = 10 -------(2)

For infinitely many solutions,

Coefficients of variables will be same.

a = 6 will be the answer.

Option B is the correct option.

Question 12,

[tex]y=-\frac{3}{2}x+4[/tex] ---------(1)

[tex]y=-\frac{3}{2}x-4[/tex] ----------(2)

Since, slopes of both the equations are same as [tex]-\frac{3}{2}[/tex], lines will be parallel.

System will have NO SOLUTION.

Question 13,

x + 3y = 6 ------- (1)

6x + 18y = 36

x + 3y = 6 -------- (2)

Both the equations are same.

Therefore, system of the equations will have infinitely many solutions.

2x - 3y = -3 ------(1)

4x + 6y = 18

2x + 3y = 9 -------(2)

Coefficients of the variables are different, therefore, one solution.

3x + 2y = 6 -------(1)

6x - 4y = 24

3x - 2y = 12 -------(2)

One solution.

8x - 10y = 6

4x - 5y = 3 -------(1)

-4x + 5y = 3

4x - 5y = -3 ------(2)

One solution.

4x + 10y = 16

2x + 5y = 8 --------(1)

10x + 25y = 40

2x + 5y = 8 --------(2)

Infinitely many solutions.

Answer:

A function is a relationship between two variables, such that one variable is determined by the other variable.

A function can be represented verbally. For example, the circumference of a square is four times one of its sides.

A function can be represented algebraically. For example, 3x+6 3 x + 6 .

A function can be represented numerically.

A function can be represented graphically.

Step-by-step explanation:

The function is defined as a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

We need to define function.

Functions are the fundamental part of calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math. These functions are usually denoted by letters such as f, g, and h. The domain is defined as the set of all the values that the function can input while it can be defined. The range is all the values that come out as the output of the function involved. Co-domain is the set of values that have the potential of coming out as outputs of a function.

Different types of a function:

The types of functions have been classified into the following four types.

Representation of functions:

There are three different forms of representation of functions.

Venn Diagram: The Venn diagram is an important format for representing the function. The Venn diagrams are usually presented as two circles with arrows connecting the element in each of the circles. The domain is presented in one circle and the range values are presented in another circle. And the function defines the arrows, and how the arrows connect the different elements in the two circles.

Graphical Form: Functions are easy to understand if they are represented in the graphical form with the help of the coordinate axes. Representing the function in the graphical form helps us to understand the changing behaviour of the functions if the function is increasing or decreasing. The domain of the function - the x value is represented along the x-axis, and the range or the f(x) value of the function is plotted with respect to the y-axis.

Roster Form: Roster notation of a set is a simple mathematical representation of the set in mathematical form. The domain and range of the function are represented in flower brackets with the first element of a pair representing the domain and the second element representing the range.

Therefore, the function is defined as a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Answer:

[tex]S_{10} = 3069[/tex]

Step-by-step explanation:

Given

[tex]Sequence = \{3, 6, 12, 24, 48...\}[/tex]

Required

Determine the sum of the first terms

First, we calculate the common ratio (r)

[tex]r = \frac{T_2}{T_1}[/tex]

[tex]r = \frac{6}{3}[/tex]

[tex]r = 2[/tex]

The required sum is:

[tex]S_n = \frac{a(r^n-1)}{r-1}[/tex]

Substitute 3 for a, 2 for r and 10 for n

[tex]S_{10} = \frac{3(2^{10}-1)}{2-1}[/tex]

[tex]S_{10} = \frac{3(1024-1)}{2-1}[/tex]

[tex]S_{10} = \frac{3(1023)}{2-1}[/tex]

[tex]S_{10} = \frac{3(1023)}{1}[/tex]

[tex]S_{10} = \frac{3069}{1}[/tex]

[tex]S_{10} = 3069[/tex]

We get 1.80 pounds of flour for 1 dollar.

Unitary method is a mathematical technique for first deriving the value of a single unit then deriving any given unit from it.

Suppose we know one mango costs 4 dollars so 20 mangoes will cost (4×20) dollars = 80 dollars.

According to the given question three pounds of flour cost 1.65 dollars.

So, One pound of flour will cost (1.65/3) dollars which is

= 0.55 dollars.

In 1 dollar we will get (1/0.55) pounds of flour which is

Answer:

  a[n] = n^2 -3n -6

Step-by-step explanation:

First differences are ...

  -8 -(-8) = 0

  -6 -(-8) = 2

  -2 -(-6) = 4

Second differences are ...

  2 -0 = 2

  4 -2 = 2

Constant second differences indicate a degree 2 (quadratic) sequence.

The general formulation can be written as ...

  an = a1 +(n -1)(d1 +(n -2)/2(d2)) . . . . where a1 is the first term; d1 is the first first difference; d2 is the second difference

  = -8 +(n -1)(0 +(n -2)/2(2)) = -8 +(n -1)(n -2)
