By solving inequality  [tex]x[/tex] ∈ [tex][-2,3)[/tex]

What is inequality?

A declaration of the relation in terms of greater, greater than or equal to, smaller, or less than or equal to between two numbers or algebraic expressions is known as inequality.

[tex]4\leq 3x+10 < 19[/tex]

Rearranging the above equation

[tex]\left \{ {{4\leq 3x+10} \atop {3x+10} < 19} \right.[/tex]

Subtracting 10 from the above equation

[tex]\left \{ {{4-10\leq 3x+10-10} \atop {3x+10-10 < 19-10}} \right[/tex]

[tex]\left \{ {{-6\leq 3x} \atop {3x < 9}} \right.[/tex]

Dividing the above equation by 3

[tex]\left \{ {{\frac{-6}{3}\leq \frac{3x}{3} } \atop {\frac{3x}{3} < \frac{3}{3} }} \right.[/tex]

[tex]\left \{ {{-2\leq x} \atop {x < 3}} \right[/tex]

[tex]-2\leq x < 3[/tex]

Therefore, by solving inequality we get  [tex]x[/tex] ∈ [tex][-2,3)[/tex]

The amount of the 1167 rupees he have to pay every month according to the interest rate.

According to the statement

We have to find that the monthly repayments.

So, For this purpose, we know that the

Interest rate is the annual rate that is charged for borrowing , expressed as a single percentage number that represents the actual yearly cost of funds over the term of a loan.

From the given information:

A couple buys furniture for R50 000. They put down a cash deposit of 20% and pay off the balance using a higher purchase agreement, over 4years. The institution charges interest of 10% p.a and monthly Insurance fee of R75.00.

Then

A couple buys furniture =  50,000

cash deposit of 20% = 20% of 50,000

cash deposit = 20/100*50,000

cash deposit = 0.2*50,000

cash deposit = 10000

Left money on which company put interest of 10% =50000 - 10,000

Left money on which company put interest of 10% = 40,000

Then

interest amount per year = 10% of  40,000

interest amount per year = 10/100*40,000

interest amount per year = 0.1*40,000

interest amount per year = 4000

It means interest paid by the customer in 4 years = 4000*4

It means interest paid by the customer in 4 years = 16000

Then

Total money he pays with interest rate in 4 years = 16000 +40,000

Total money he pays with interest rate = 56000

Then

The money he have to pay every month in 4 years = 56000/48

The money he have to pay every month in 4 years = 1167.

So, The amount of the 1167 rupees he have to pay every month according to the interest rate.

Answer:

w = 20m

l = 60m

Step-by-step explanation:

P = 2l + 2w

We know the perimeter = 160 and we know that l = 3w, so write what we know and solve for w.

P = 2l x 2w

160 = 2(3w) + 2w

160 = 6w + 2w

160 = 8w

Divide both sides by 8

20 = w

Every six powers of ten, the cycle repeats. In other words, a repeating decimal with a denominator of 7 can have a repeating cycle that is up to six digits long.

The repeating cycle of a repeating decimal for the rational number with a denominator of 7 can be determined by considering the factors of the denominator.

In this case, the denominator is 7, which is a prime number. The length of the repeating cycle can be determined by examining the powers of 10 modulo 7.

To find the length of the repeating cycle, we need to find the smallest positive integer "n" for which 10ⁿ - 1 is divisible by 7. In other words, we are looking for the smallest "n" such that 10ⁿ ≡ 1 (mod 7).

Let's calculate the powers of 10 modulo 7:

10¹ ≡ 3 (mod 7)

10² ≡ 2 (mod 7)

10³ ≡ 6 (mod 7)

10⁴ ≡ 4 (mod 7)

10⁵ ≡ 5 (mod 7)

10⁶ ≡ 1 (mod 7)

As you can see, the cycle repeats every 6 powers of 10. This means that the repeating cycle of a repeating decimal with a denominator of 7 can be up to six digits long.

If we add the probability of 1 student showing up, 2 students to show up, 3 students to show up, and 4 students showing up

We get 0.10+ 0.20+ 0.25+ 0.15 =1

As the sum of these individual 4 possibilities is 1 that means these are the only possibilities  to exit

Now we need to find out  the probability of at least 2 students showing up which means the probability of two or more students showing up

The value of the middle integer is 26

From the question, we are to determine the middle integer

From the given information,

"The sum of the squares of three consecutive positive integers is 2030"

Let the first integer be x,

Then the middle integer will be x + 1

and the third integer will be x + 2

Thus,

x² + (x +1)² + (x +2)² = 2030

x² + x² + 2x + 1 + x² + 4x + 4 = 2030

3x² + 6x + 5 = 2030

3x² + 6x + 5 - 2030 = 0

3x² + 6x - 2025 = 0

x² + 2x - 675= 0

Solve quadratically

x² + 27x - 25x - 675 = 0

x(x + 27) -25(x + 27) = 0

(x - 25)(x + 27) = 0

x - 25 = 0 and x + 27 = 0

x = 25 and x = -27

Since x is a positive integer,

x = 25

Thus,

The middle integer,

x + 1

= 25 + 1

= 26

Hence, the value of the middle integer is 26

option B. g(x)=-2, x<-2, option D. g(x)=-2x+6, x>1 and option E. g(x)=x/2+1 represent a piece of the function in given graph.

The graph of a function is a collection of all ordered pairs of the relation. These are usually represented as points in a Cartesian coordinate system. It is a relationship between an independent variable and a dependent variable. The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x).

Reasons are given below:

In first option that is g(x)=-2x, -2<x<0, we can see a negative sign which indicates that the graph should be downward (negative slope). Also, g(x)=-2x has no y-intercept therefore g(x)=-2x, -2<x<0 does not represent a piece of the function in given graph.

In second option that is g(x)=-2, x<-2, we can see a negative sign and no y-intercept which indicates that it is a horizontal line parallel to x-axis. Also given that x is less than -2, therefore the line should move away from y-axis to the left where lies more negative values. The given data matches the slope given in third quadrant. Hence, it represents a piece of function in given graph.

In third option that g(x)=x-2, -2<x<1, we can see that the function indicates that it has y-intercept at y=-2 and a slope of value 1(positive) which means it should move in upward direction and must cut y-axis at y=-2. The given data does not match with the graph given. Hence, it does not represent a piece of function in the given graph.

In fourth option that is g(x)=-2x+6, x>1, we can see negative sign therefore it should be downward and +6 indicates that it is  with y-intercept too. Hence the given data matches with the graph given and therefore it represents a piece of the function in the given graph.

In fifth option that is g(x)=x/2+1, -2<x<1. As we can see, x lies between -2 and 1, to understand let us assume x=2 then x/2=2/2=1. Therefore, the slope can start at x=1 and extend till -2. Hence, it represents a piece of the function in the given graph.

Therefore, Functions g(x)=-2, x<-2, g(x)=-2x+6, x>1 and g(x)=x/2+1 represent a piece of the function in the given graph.
