What is the answer for
-6n-2n=16

So if you're asked to graph a function and its inverse, all you have to do is graph the function and then switch all x and y values in each point to graph the inverse. Just look at all those values switching places from the f(x) function to its inverse g(x) (and back again), reflected over the line y = x.

The equation of the line across which all inverses reflect is y = x. This reflection principle applies to linear functions, hyperbolas, and other mathematical relations where inverses can be found by interchanging the roles of x and y.

The equation of the line that all inverses reflect across is y = x. This is because when you are finding the inverse of a function, you swap the x and y variables, thus mirroring the original function across the line y = x. If you have a linear function in the slope-intercept form (y = mx + b), and you find its inverse, assuming the function is one-to-one and therefore has an inverse, you would essentially swap the x and y coordinates, resulting in the equation of its inverse. This process reflects each point of the original function across the line y = x.

As an example, for a line with an equation y = -x + 1, the inverse when reflected across the line y = x would result in swapping x and y to get x = -y + 1, which when solved for y, gives the inverse function's equation. Conversely, for a function expressed in another form, such as a hyperbola or a set of simultaneous linear equations, the principle is the same: to find the inverse, interchange the roles of the dependent and independent variables. For instance, a hyperbola described by y = a - b/x could have its inverse derived by interchanging x and y, leading to the inverse relation x = a - b/y.

To find the perimeter of the bedroom floor, subtract the rug's length and width from the floor's length and width. Then, use the formula 2(length + width) to calculate the perimeter. The perimeter of the bedroom floor is 64 ft.

To find the perimeter of the bedroom floor, we need to subtract the length and width of the rug from the length and width of the floor. The length of the floor is 10 ft and the rug leaves 1 ft exposed on each side, so the length of the rug is 8 ft. Similarly, the width of the floor is 8 ft and the rug leaves 1 ft exposed on each side, so the width of the rug is 6 ft. Therefore, the perimeter of the bedroom floor is 2(10 ft + 8 ft) + 2(8 ft + 6 ft) = 2(18 ft) + 2(14 ft) = 36 ft + 28 ft = 64 ft.

Answer:

aₙ = a₁ . 5⁽ⁿ⁻¹⁾

Step-by-step explanation:

The first term in the sequence is a₁ = 6.

a₂ = 30. a₃ = 150.

We see that each consecutive term is multiplies by 5 to arrive at the next term.

That is: a₂ = 30 = a₁ . [tex]$ 5^{2 - 1}  = 5 $[/tex] = 6.5 = 30.

Similarly, a₃ = 150 = 6 [tex]$ \times $[/tex] [tex]$ 5^{3 - 1} = 5^2 = 25 $[/tex]

Generalizing this, we have:

aₙ = a₁ . [tex]$ 5^{n - 1} $[/tex]

This is called the recursive formula of the sequence.

Answer:

30 miles

Step-by-step explanation:

We know

D = RT

Where

D is the distance

R is the rate

T is the time

Towards Island:

R = 15

Let time be x

So, we can write:

D = 15x

Return from Island:

R = 10

Let time be y

So, we can write:

D = 10y

Also, total time is 5 hours, so we can write:

x + y = 5   [equation 2]

Now, since the distance for both legs of the journey is equal, we can write:

Distance 1 = Distance 2

15x = 10y

Now we replace this equation with equation 2, so we get:

Equation 2: x + y = 5 or x = 5 - y

15x = 10y

15(5 - y) = 10y

75 - 15y = 10y

75 = 25y

y = 75/25

y = 3

Distance 2 = D = 10y

Replacing y with 3, we get:

D = 10y

D = 10(3)

D = 30

So, the distance to island is 30 miles

Answer:

g+4-5

Step-by-step explanation:

because the plus would go first anyways.

The kinetic energy (Ek) of the car with a mass of 1000 kg moving at a speed of 20 m/s is calculated using the formula Ek = 0.5 * m * v². Substituting the given values, we find the kinetic energy to be 2.00 x 10⁵ Joules.

To calculate the kinetic energy (Ek) of a car with a given mass and speed, you can use the formula Ek = 0.5 * m * v², where m is the mass, and v is the speed. In this case, the mass (m) of the car is 1000 kg, and the velocity (v) is 20 m/s.

Substituting the given values into the formula, we have Ek = 0.5 * (1000 kg) * (20 m/s)². This simplifies to Ek = 2.00 x 10⁵ J (Joules), which is the kinetic energy of the car.

It's important to note that kinetic energy always has units of Joules in the International System (or SI), and it represents the energy that an object has due to its motion.

 Answer:

Number of Adult's tickets sold on Saturday = 3,356

Number of Children's tickets sold on Saturday = 2, 928

Total number of tickets sold over these two days is 8,938.

Step-by-step explanation:

Here, the number of tickets sold on FRIDAY:

Adult Ticket sold = 1,678

Children's Tickets sold = 976

So, the total number of tickets sold on Friday  

= Sum of ( Adult + Children's ) tickets  = 1,678  + 976 = 2,654 ....  (1)

The number of tickets sold on SATURDAY:

Adult Ticket sold =   2 times  the number of adult tickets sold on Friday  

                             =  1,678 x 2  = 3,356

Children's Tickets sold = 3 x the number of children's tickets sold on Friday.

                                      =  976  x 3 = 2, 928

So, the total number of tickets sold on Saturday  

= Sum of ( Adult + Children's ) tickets  = 3,356 + 2,928 = 6, 284 ....  (2)

Now, the total number of tickets booked in these two days :

Sum of tickets booked on (Friday + Saturday)

= 2,654 +  6, 284  =   8,938

Hence, total number of tickets sold over these two days is 8,938

Answer:

The total amount of money Alex spends on 5 DVD = $ 35.

Step-by-step explanation:

Total number of DVD purchased by Alex = 5

The cost of each DVD = $9

So, the total cost of purchasing 5 DVD = 5 x ( csot of 1 DVD)

= 5 x ( $ 9) = $ 45

Now , the discount if 1 DVD = $ 2

So, the total discount of 5 DVD = 5 x ( Discount on1 DVD)

= 5 x ($ 2) = $ 10

⇒ The total amount Alex spends

= Total cost of 5 DVD - Discount on 5 DVD

= $ 45 - $ 10 = $ 35

Hence, the total amount of money Alex spends on 5 DVD = $ 35.

Answer:

The correct answer is D. 414 in squared.

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Area of the first circle = 11.5 inches ²

2. Let's calculate the area of the new circle, given that the radius of the first circle is multiplied by 6.

Area of the first circle = 11.5 inches ²

Let's find the radius:

π * r² = 11.5

r² = 11.5 / 3.1416

r² = 3.66055513

r = 1.91 inches

The first circle has a radius of 1.91 inches

So, the radius of the second circle is 1.91 * 6 = 11.48 inches

Area of the second circle = π * r²

Area of the second circle = 3.1416 * 11.48²

Area of the second circle = 3.1416 * 131.79

Area of the second circle = 414.03 inches ²

Area of the second circle = 414 inches ² (Rounded to the nearest whole number)

The correct answer is D. 414 in squared.

Answer: Y=-1 or Y=-1+4

Step-by-step explanation:

To find the equation of a line parallel to the given line and passing through a specific point, we can use the point-slope form of a linear equation.

To find the equation of a line that is parallel to the given line and passes through the point (3, 1), we need to use the fact that parallel lines have the same slope. Since the given line has a slope of 4, the parallel line will also have a slope of 4. Using the point-slope form of a linear equation, we can write the equation as:

y - y1 = m(x - x1)

Plugging in the values from the given point (3, 1) and the slope (4), we get:

y - 1 = 4(x - 3)

Simplifying the equation, we have:

y - 1 = 4x - 12

y = 4x - 11

Therefore, the equation of the line that is parallel to the given line and passes through the point (3, 1) is y = 4x - 11.

Answer:

The number of terms of the G.P. is 6

Step-by-step explanation:

Let the G.P. has first term a, common ratio r and the number of terms n.

The G.P. has first term 2, so a = 2.

Now, the fourth term is 54 i.e. ar³ = 54

⇒ 2r³ = 54

⇒ r³ = 27

⇒ r = 3

Now, the last term i.e. the nth term is= [tex]ar^{n - 1} = 486[/tex]

⇒ [tex]2 \times 3^{n - 1} = 486[/tex]

⇒ [tex]3^{n - 1} = 243 = 3^{5}[/tex]

{Which is the distributive property of division}

Answer:

42 years, 9 months

Step-by-step explanation:

Using the compound interest formula Accrued Amount = P (1 + r/n)^(nt)

where Accrued amount (A) which is quadruple the initial deposit

A = 4 x 500 = $2000

P = principal; $500

r = 3.25% = 0.0325

t = number of years

n = number of times interest is compounded = 12 for monthly

Therefore

2000 = 500 (1 + 0.0325/12)^(12t)

Therefore

(1.002708)^12t = 2000/500

(1.002708)^12t = 4

finding the log of both sides

12t x log 1.002708 = log 4

12t x 0.001174 = 0.6021

12t = 0.6021/0.001174

12t = 512.83

t = 512.83/12

t = 42.7

which is estimated as 42 years, (0.7 x 12 = 9) months

hence it takes about 43 years to quadruple the deposit

The number of years it will take to be the amount by quadruple will be 42.7 years.

Compound interest is applicable when there will be a change in the principal amount after the given time period.

As per the given,

The total amount will be,

A = 4 × 500 = $2000

Principle amount P = $500
Rate of interest r =  3.25% = 0.0325

The time period is t.

n = number of times interest is compounded

n = 12

By compound interest formula,

2000 = 500 [tex](1 + 0.0325/12)^{12t}[/tex]

(1.002708)^12t = 2000/500

(1.002708)^12t = 4

Take logs on both sides,

12t × log 1.002708 = log 4

12t × 0.001174 = 0.6021

12t = 0.6021/0.001174

12t = 512.83

t = 512.83/12

t = 42.7

Thus, the time period will be 42.7 years.

Hence "The number of years it will take to be the amount by quadruple will be 42.7 years.".
