t should have constraint as in the real world, t is the number of years from 2000,  

T { t ∈ N U {0} | 0 ≤ t ≤ 20} and W = { w ∈ R | w = 0.5t + 47 and 0 ≤ t ≤ 20}

What is the constraint?

A constraint is a condition of an optimization problem that should be satisfied the condition. A cost constraint means that you're limited to a specific project budget, while a time constraint means you must complete your project within a specified timeframe.

The equation W(t) = 0.5t + 47 models the percentage of the population in Guatemala that has access to safe drinking water,

where t represents the number of years since 2000, and W represents the percentage of the population that has access.

Because the data has been collected from 2000 to 2020 and the modelling function is developed on the basis of the collected data. Hence, t should have constraint as in the real world, t is the number of years from 2000.

Because t is the number of years from 2000. Data is collected til 2020, i.e. t=0 to 20,

Let T be the set of all values of t.

T { t ∈ N U {0} | 0 ≤ t ≤ 20}

Because W(t) = 0.5t + 47

Let W be the set of all values of W.

W = { w ∈ R | w = 0.5t + 47 and 0 ≤ t ≤ 20}

Hence, t should have constraint as in the real world, t is the number of years from 2000,  

T { t ∈ N U {0} | 0 ≤ t ≤ 20} and W = { w ∈ R | w = 0.5t + 47 and 0 ≤ t ≤ 20}

The weekly gross pay is 1040. The solution is obtained using arithmetic operations.

What are arithmetic operations?

There are four basic operations which are listed as follows:

•Addition(‘+’): This operation deals with finding the sum.

•Subtraction(‘-’): This operation deals with finding the difference.

•Multiplication(‘×’): This operation deals with finding the product.

•Division(‘÷’): This operation deals with finding the quotient.

Assumption: Weekly working hours are 40.

Since, the hourly rate is 20 per hour and working hours per week are 40

So, the weekly pay comes out to be 40*20= 800

The overtime rate is time and a half which comes out to be

20*1.5= 30 per hour

The overtime hours are 48-40=8 hours

So, the weekly overtime pay comes out to be 8*30= 240

The total pay= 800+240= 1040

Hence, the weekly gross pay is 1040.

In mathematics, an inequality is a linking of two equations or numbers when there isn't an equal sign. Unbalance therefore precedes inequity. When two numerical values are not equal, an inequality results in a relationship between them. Egality and inequality are not the same. Where variables are not similar or equal, have used the most common symbol (). There are various inequalities that can be utilized to contrast values regardless of how small or huge they are. Switching the two sides it until variables represent all that is left can address a variety of basic inequality problems. The combination or division with low values from both sides are only a few examples of the many factors that might cause inequality. You switch sides and the left.

An inequality equivalent to 6x+12≥48 is 3x+6≥24.

What is inequality?

Inequality means not equal. Generally, if two values are not equal, we use the “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used.

This is because dividing both sides of the original inequality by 6 results in 3x + 6 ≥ 24.

In option B, C and D, the inequality is not equivalent to the original inequality, as they have different values on one side of the inequality sign.

In option B: 3x+12≥24, the left side of the inequality is greater than the left side of the original inequality.

In option C: 3x+12≥18, the right side of the inequality is lesser than the right side of the original inequality.

In option D: 3x+21≥24, the left side of the inequality is greater than the left side of the original inequality and the right side of the inequality is greater than the right side of the original inequality.

Answer:

a₆ = -13

Step-by-step explanation:

A recursive formula for a sequence allows you to find the nth term of the sequence provided you know the value of the previous term in the sequence.  Therefore, when giving a recursive rule, we need to define the first term of the sequence, as it is not part of the formula.  

Given recursive rule:

[tex]\begin{cases}a_1=7\\a_n=a_{n-1}-4\end{cases}[/tex]

To find the value of a₆, use the recursive formula to find the first 6 terms of the sequence:

[tex]a_1=7[/tex]

[tex]a_2=a_1-4=7-4=3[/tex]

[tex]a_3=a_2-4=3-4=-1[/tex]

The single shift is 1.5 hours long if 2+3/4 hours equals 1+5/5 equal length shift.

Fractions are referred to in mathematics as the components of a whole. The entire can be a single item or a collection of items. When we slice a cake in real life, the portion represents the proportion of the cake that was originally cut. The word "fraction" has its roots in Latin. "Fractus" is the Latin word for "broken." The fraction was first expressed verbally in antiquity. Later, a numerical form was developed.

Paola contributed to the community garden for 2 + 3 / 4 hours this week, or a 1 + 5 / 6 times length of shift.

We must determine the duration of a single shift.

The correct fraction of the given mixed fractions must first be determined.

Numerator and denominator combine to form a fraction.

The numeral that appears above the division symbol is referred to as the numerator, while the numeral that appears below the division symbol is referred to as the denominator.

2+3/4=(8+3)/4=11/4

1+5/6=(6+5)/6=11/6

F and G are inverse if both of them satisfy the condition h(x)=x. f(g(x))=g(f(x))=x, as we discovered. The argument f(x) and g(x) are inverse functions is thus established.

If f (x) and g (x) are inverse functions, it can be determined using one of two ways. For more information, see the explanation.

Explanation:

Instance 1

Inverse functions of both functions can be found using the first method.

Example.

Inverse of f (x) = x + 7 is what we're looking for.

We attempt to determine x using the equation y = x + 7.

y = x + 7

Inferring that g (x) is the inverse of f (x) from the fact that x = y 7

Finding g (x inverse )'s is now necessary.

g( x ) = x − 7

y = x − 7

x = y + 7

As a result, we discovered that f (x) is the inverse function of g (x).

f and g are equal if g is inverse of f and vice versa.

The second approach entails locating the compound functions f ( g ( x ) ) and g ( f ( x ) ). In this case, f and g are inverse if they are both h (x ) = x.

Example:

f ( g ( x ) =  [ x − 7 ] + 7

G ( x ) placed as x is the expression in brackets.

f ( g ( x ) ) = x − 7  + 7 = x

g (f ( x ) =  [ x + 7 ] − 7

f ( x ) inserted as x is the expression in brackets.

g ( f ( x ) ) = x + 7 − 7 = x

The equation f ( g ( x ) ) = g ( f ( x ) ) = x was what we discovered. The argument f (x) and g (x) are inverse functions is thus established.

The length of the line segment AC is 20 units.

A line segment is bounded by two distinct points on a line.

The length of AC is x + 9. The actual length of the line segment AC can be found as follows:

Therefore, using equations,

AB + BC = AC

AB = 3x - 15

BC = x - 9

AC = x + 9

Hence,

AC = AB + BC

x + 9 =  3x - 15 + x - 9

x + 9 = 3x + x - 15 - 9

x + 9 = 4x - 24

x - 4x = -24 - 9

-3x = -33

divide both sides by -3

x = -33 / -3

x = 11

Therefore,

AC = 11 + 9 = 20 units

We can start solving this problem using algebra. Let x be the price of the lower section seats. Then the price of the upper level seats is x - 10.

We know that there are a total of 8000 seats in the arena, and 3000 of them are upper level seats. So the remaining seats are in the lower section, which means there are 5000 lower section seats.

We also know that the total revenue for a sellout is $194,000. We can use this information to set up an equation to represent the total revenue:

(x - 10) * 3000 + x * 5000 = 194000

Now we can use this equation to solve for the price of the lower section seats (x).

3000(x-10) + 5000x = 194000

3x - 30,000 + 5x * 10^4 = 194000

8x = 224,000

x = 28000/8 = 3500

Therefore, the price of the lower section seats is $3500 and the price of the upper level seats is $3500 - $10 = $3490.

The sinusoidal function can be represented as:

[tex]$y = A \sin(Bx + C) + D$[/tex]

Where A is the amplitude, B is the b, C is the phase shift, and D is the vertical shift.

Given that the y-intercept is 2, the vertical shift D is 2.

Given that the midline y = 2, the average value of the function is 2, so the sum of the maximum and minimum value is 4 which means the maximum value is 4, the amplitude of the function is 4-2 = 2.

Given that the maximum value of 4 is at [tex]π/4[/tex] , the phase shift C is π/4.

Given that it completes 2 cycles in the interval [0,2π], the frequency B is
