Answer:

- 133

Step-by-step explanation:

To find the 30 th term substitute n = 30 into the formula, that is

[tex]a_{30}[/tex] = 12 - 5(30 - 1) = 12 - (5 × 29) = 12 - 145 = - 133

Final answer:

The 30th term of the sequence defined by an = 12 – 5(n – 1) is – 133.

Explanation:

To calculate the 30th term of the sequence given by an = 12 – 5(n – 1), we start by substituting the value of n with 30.

[tex]a_{30}[/tex] = 12 – 5(30 – 1)

[tex]a_{30}[/tex] = 12 – 5(29)

[tex]a_{30}[/tex]   = 12 – 145

[tex]a_{30}[/tex] = – 133

The 30th term of the sequence is – 133.

The midline equation for the sinusoidal function is y = 4 sin(ωx + ∅) - 3, derived by calculating the amplitude and vertical shift within the general function equation.

A function is a mathematical expression, rule, or law that defines the relationship between one variable and another. In mathematics, functions play a crucial role in representing physical relationships and various mathematical concepts. One specific type of function is the sinusoidal function, characterized by its repetitive pattern within a specific time interval.

The general form of a sinusoidal function is given by the equation:

y = A sin(ωx + ∅) + c

Here, A represents the amplitude, ω is the argument, ∅ is the phase difference, and c is the vertical shift known as the midline.

To find the equation of the midline, we use the formula:

A = (Maximum value - Minimum value) / 2

Given that the maximum value is 1 and the minimum value is -7, the amplitude (A) is calculated as:

A = (1 - (-7)) / 2 = 4

The vertical shift (c) is determined to be -3. Substituting these values into the general equation, we obtain the equation of the midline for the sinusoidal function:

y = 4 sin(ωx + ∅) - 3

In summary, the equation of the midline for the sinusoidal function is y = 4 sin(ωx + ∅) - 3.

The amplitude and vertical shift inside the general function equation are used to obtain the midline equation for the sinusoidal function, which is y = 4 sin(ωx + ∅) - 3.

A mathematical phrase, rule, or law that establishes the connection between two variables is called a function.

Functions are essential to the representation of both mathematical concepts and physical relationships in mathematics.

The sinusoidal function is one particular kind of function that is distinguished by its repeating pattern inside a predetermined time frame.

The following formula provides the generic form of a sinusoidal function:

sin(ωx + ∅) + c = A

In this case, amplitude is denoted by A, argument by ω, phase difference by ∅, and vertical shift, or midline, by c.

We utilise the to determine the midline's equation.

A is equal to (Maximum - Minimum) / 2.

A = (1 - (-7)) / 2 = 4 is the formula for calculating the amplitude (A), given that the maximum value is 1 and the minimum value is -7.

It is found that the vertical shift (c) is -3. The equation of the midline for the sinusoidal function is obtained by substituting these values into the general equation: y = 4 sin(ωx + ∅) - 3

In conclusion, y = 4 sin(ωx + ∅) - 3 is the equation of the midline for the sinusoidal function.

Answer:

The graph of y = f(x) will shift left 6 units, as shown in figure a.

Step-by-step explanation:

A translation means we are able to move the graph of a function up or down - normally called Vertical Translation -  and right or left - commonly called Horizontal Translation.

If we replace the graph of y = f(x) with the graph of y = f(x + 6). It means we have added 6 units to the input, meaning the graph y = f(x) will shift left by 6 units as 6 is being added directly to the  x, so it is f(x + 6).

For example, if y = x² is the original function and of 6 is directly added to x i.e. f(x + 6), making it y = (x + 6)². So, we can easily observe that there will be a horizontal translation left of 8 units, as shown in figure a.

So, the graph of y = f(x) will shift left 6 units.

The graph of y = f(x) will shift left 6 units. The correct option is the third one.

For any function y = f(x), we define an horizontal translation of N units as:

y = f(x + N)

Where if:

N > 0, the translation is to the left.

N < 0, the translation is to the right.

Here we have:

y = f(x + 6)

So this is a translation of 6 units to the left.

Answer:

The given expression at p = 5 can be written as:

[tex]4(p^4)  > 2p -3[/tex]

Step-by-step explanation:

Here, the given expressions are:

[tex](4p^4 ), (2p-3)[/tex]

Now, substitute the value of p = 5 in both the given expressions, we get:

[tex]4(p^4)  = 4(5^4)  = 4 (625)   =  2,500\\\implies 4(p^4) = 2,500[/tex]

Similarly,

[tex](2p-3)  = 2(5) - 3 = 10 -3 = 7\\\implies 2p - 3  = 7[/tex]

So,now comparing  both the values at p = 5, we get:

2,500 > 7

[tex]\implies 4(p^4)  > 2p -3[/tex]

Hence, the given expression at p = 5 can be written as:

[tex]4(p^4)  > 2p -3[/tex]

To compare the two plans and find the amount of driving for which they cost the same, we can set up an equation and solve for x. The two plans cost the same for 450 miles of driving.

To compare the two plans and find the amount of driving for which they cost the same, we need to set up an equation. Let's assume the amount of driving is represented by the variable x. The total cost for Plan 1 can be calculated as:

Total cost = $46 + $0.13x

The total cost for Plan 2 can be calculated as:

Total cost = $55 + $0.11x

We can set the two equations equal to each other and solve for x:

$46 + $0.13x = $55 + $0.11x

$0.02x = $9

x = $9 / $0.02 = 450

Therefore, the two plans cost the same for 450 miles of driving.

The equation which represents the amount of minutes.m that it will take to fill the pool is 200 = 60 + 10m

Which equation represents the amount of minutes ( m) that it will take to fill the pool?

Let

m = amount of minutes that it will take to fill the pool

Gallons of water in the pool = 60 gallons

Capacity of the pool = 200 gallons

Additional gallons added per minutes = 50 gallons / 5

= 10 gallons per minutes

The equation:

200 = 60 + 10m

200 - 60 = 10m

140 = 10m

Divide both sides by 10

m = 140/10

m = 14 minutes

Therefore, it takes Anita 14 minutes to fill the pool.

The initial fee of a train ticket, given a constant fee per stop, can be calculated by finding the constant fee per stop and subtracting the total of this fee for a given number of stops from the total price for those stops. By this calculation, the initial fee is $2.50.

To determine the initial fee that is related to the price of a train ticket, which consists of an initial fee plus a constant fee per stop, we should first calculate the cost per stop. We can do this by subtracting the price of a ticket for 3 stops from the price of a ticket for 7 stops. So, we get $12.50 - $6.50 = $6.00. We find the difference in the number of stops, which is 7 - 3 = 4 stops. Divide the total price difference by the difference in the number of stops to get the constant fee per each stop: $6.00 / 4 stops = $1.50 per stop. Now we know the constant fee for each stop, so we subtract that from the total price for 3 stops to find the initial fee: $6.50 - ($1.50 * 3) = $2.50. So, the initial fee is $2.50.

To find the initial fee, we need to determine the additional cost per stop. We can do this by using the formula y = mx + b, where y represents the price of the ticket, x represents the number of stops, m represents the constant fee per stop, and b represents the initial fee.

Using the given data, we can set up two equations using the points (3, 6.50) and (7, 12.50).

By subtracting these two equations, we can determine the value of b, which represents the initial fee. Thus, the initial fee is $3.

Answer:

Step-by-step explanation:

x = number of cars

12x = 3.50x + 34

12x - 3.50x = 34

8.5x = 34

x = 34/8.5

x = 4 <=====he would have to sell 4 cars

In this case, Luke must sell [tex]\(\boxed{4}\)[/tex] cars for his revenue to equal his expenses.

To determine how many cars Luke must sell for his revenue to equal his expenses, let's define the variables and set up the equation.

Let x be the number of cars Luke sells.

Revenue:

Luke sells each car for $12, so his revenue for selling x cars is:

[tex]\[ \text{Revenue} = 12x \][/tex]

Expenses:

Luke's expenses include $3.50 per car and a fixed cost of $34 for tools. So his total expenses for x cars are:

[tex]\[ \text{Expenses} = 3.50x + 34 \][/tex]

We need to find the number of cars x such that his revenue equals his expenses:

12x = 3.50x + 34

To solve for x  subtract 3.50x  from both sides:

12x - 3.50x = 34

8.50x = 34

Now, divide both sides by 8.50:

[tex]\[ \text{Expenses} = 3.50x + 34 \][/tex]

x = 4

Therefore, Luke must sell [tex]\(\boxed{4}\)[/tex] cars for his revenue to equal his expenses.
