what is the perimeter of a sector of a circle of radius 6cm with a sector angle of 35°?​

Yes, the function f(x)=2x-3 is a one-to-one function.

The Inverse of a Function:

The inverse of a function can be computed if the function can be proven to be one-to-one. Take the one-to-one function and compute its inverse by interchanging x and y in the expression and solving for y.

Graphically, then, the graphs of the function and its inverse are the reflections of each other about the line y=x.

Use the definition to test the one-to-one of f.

Let x and x be the elements in the domain off and assume f(x₁)=f(x₂)

2x₁-3=2x₂-3

2x₁=2x₂

x₁=x₂

since f(x₁)=f(x₂) implied x the function f is one-to-one.

Total charge that Tom has to pay is $142.2, and the express function for the monthly charge is c(x) = 105 + (x -4) * 12

As per data given, monthly value given is $105 = free text + free call + 4gb  and extra gigabyte x $12. Tom that use 7.1 of data will be charge as follow:

Tom charge = normal use + extra use

To charge = 105 + extra gigabyte x12

Extra gigabyte = tom use - normal use

Extra gigabyte = 7.1 - 4

Extra gigabyte = 3.1

Tom charge = 105 + 3.1 x 12

Tom charge = 105 + 37.2

Tom charge = 142.2

The expression of monthly charge, since we have already define that value is $105 = free text + free call + 4gb and extra gigabyte x $12. We can see that text is not charge and call is not charge. So the formula will be:

Monthly charge = 105 + (extra gigabyte - 4) x 12

As per question said the variable for extra gigabyte is x and monthly charge is c(x) then

c(x) = 105 + (x - 4) * 12

Answer:

x = -3, -1, 1, 3.

Step-by-step explanation:

x^4 - 10x^2 + 9 = 0

Step 1

Let t = x^2

So , we have the quadratic

t^2 - 10t + 9 = 0

Step 2

Factorise:

(t - 1)(t - 9) = 0

Step 3

So, t - 1 = 0 or t - 9 = 0

t = 1, 9.

But t = x^2

So, we have x^2 = 1 or x^2 = 9

So, x = ±1, ±3.

x = -3, -1, 1, 3.

The value of exponential growth  after 327 minutes is 1870.

Exponential growth is the process by which quantity increases over time. It occurs when a quantity's instantaneous rate of change with respect to time is proportional to the quantity itself.

An exponential function depicts the relationship between an input and an output by using repeated multiplication on an initial value to obtain the output for any given input.

We are aware that

The exponential growth equation is equal to

y = a(1 + r)ˣ

where

an is the starting point.

r denotes the growth rate.

x represents the time in hours.

y is the quantity's value.

We now have

a = 1800

r = 0.7%

 = 0.7/100

 = 0.007

By substituting,

y = 1800(1 + 0.007)ˣ

x = 5.45 hr

y = 1800(1.007)^5.45

y = 1869.748182

Write the division as a fraction

-1/7f=-8

Multiply both sides of the equation by -7

f=56

Answer:

f = 56

Step-by-step explanation:

Given statement,

→ f divided by -7 is -8.

Forming the equation,

→ f/-7 = -8

Now the value of f will be,

→ f/-7 = -8

→ f = -8 × -7

→ f = 8 × 7

→ [ f = 56 ]

Hence, the value of f is 56.

Answer:

Below

Step-by-step explanation:

The point-slope form of a line is:

y - y1 = m(x - x1)

Where m is the slope of the line and (x1, y1) is a point on the line.

Given that the line contains the point (-2, 1) we know that this point is on the line, so we can use it as (x1, y1) in the point-slope form.

By using the point (-2,1) we can write the point-slope form of the line as:

y - 1 = m(x + 2)

This means that the point-slope form of a line with slope that contains the point (-2, 1) is y - 1 = m(x + 2) where m is the slope of the line.

The y-value of the solution to the system of equations 3x + 5y = 1 and 7x + 4y = - 13 is 2.

In the given question, we have to solve the y-value of the solution to the system of equations.

3x + 5y = 1..................(1)

7x + 4y = -13...............(2)

Multiply equation 1 by 4 and equation 2 by 5, we get

12x + 20y = 4................(3)

35x + 20y = -65................(4)

Subtract equation 4 by 3, we get

23x = -69

Divide by 23 on both side, we get

x = -3

Now putting the value of x in the equation 1, we get

3(-3) + 5y = 1

-9 + 5y = 1

Add 9 on both side, we get

5y = 10

Divide by 5 on both side, we get

y = 2

Hence, the y-value of the solution to the system of equations 3x + 5y = 1 and 7x + 4y = - 13 is 2.

Original Price: $10.90

Student Discount: 20% of 10.90 = 2.18

Subtotal: 10.90 - 2.18 = 8.72

Tax Rate: 5.75% of 8.72 = 0.50

Yes, I would like to purchase a ticket for the movie. The original price of the ticket is $10.90. As a student, I am eligible for a 20% discount, which when applied to the original price brings it down to $8.72. To calculate the final sale price, I then need to factor in the 5.75% tax rate. This is done by multiplying the subtotal of $8.72 by 0.0575, which gives me a tax amount of $0.50. When this amount is added to the subtotal, the final sale price becomes $8.37.

Answer:

Step-by-step explanation:

To prove that sinA/(1-cosA) = 1/cosA, we will start with the left-hand side and simplify it using trigonometric identities.

sinA/(1-cosA) = sinA/(1-cosA) * (sin^2A + cos^2A) / (sin^2A + cos^2A)

= (sinAsin^2A + sinAcos^2A) / (sin^2A + cos^2A - sin^2AcosA - cos^2AcosA)

= (sinAsinAcosA + sinAcosAcosA) / (sinAcosA - cosAcosA)

= sinA/cosA / (sinA/cosA - 1)

= 1/cosA

Therefore, sinA/(1-cosA) = 1/cosA, which is true.

The shrink-wrapped carton of 64 juice boxes contained 2 gallons of juice.

To find out how many gallons of juice were in the shrink-wrapped carton, we first need to convert the number of juice boxes to cups and then convert that amount to gallons.

Each juice box contains 1/2 cup of juice, so 64 boxes contain 64 * (1/2) = 32 cups.

There are 16 cups in 1 gallon, so to convert 32 cups to gallons, we divide 32 cups by 16 cups/gallon.

32 cups / 16 cups/gallon = 2 gallons

The hypotenuse's square length is equal to the sum of the squares of the lengths of the other two sides of the right-angled triangle, according to the Pythagorean theorem, commonly known as the Pythagoras theorem.

Here, The 75 inches represents the length of diagonal of the TV because the length of TV is always measured diagonally. So, the diagonal's length is 75 inches.

We've width as 43.25 inches.

Since TV is of the shape of rectangle, we can calculate the height by applying Pythagoras theorem.

So, we've   hypotenuse² = (side 1)² + (side 2)²

It can be written as,

                   diagonal² = height² + width²

                   (75)² = height² + (43.25)²

                  height² =  (75)² -  (43.25)²

                               = 5625 - 1870.5625

Step-by-step explanation:

For this problem, you would simply need to plug in the values and see if the inequality is true, and if it is, it is a solution, so let's go through the options.

Plugging in x = -4 gives us: -4 < 12 which is true since negative four is less than positive twelve, so this is a solution.

Plugging in x = 0 gives us: 0 < 12 which is true since zero is less than twelve, so this is a solution.

Plugging in x = 12 gives us: 12 < 12 which is false since twelve is not less than twelve but is rather equal to it. if the less than symbol had a line under it, it would also include values equal to it in which case x = 12 would be a solution but since it doesn't, this is not a solution.

Plugging in x = 13 gives us: 13 < 12 which is false since thirteen is not less than twelve but is rather greater than it, so this is not a solution.

The other equation of the system of linear equation that has no solution is y = 2x - 2.

If a system of linear equations has no solution, it means that the equations are inconsistent, which means that the two lines represented by the equations will not intersect. Therefore, the lines are parallel with each other.

One way to find the equation of the other line that would make the system inconsistent is to find the equation of a line that is parallel to the given equation but has a different y-intercept.

The given equation is in slope-intercept form, y = mx + b, where m is the slope (in this case, m = 2) and b is the y-intercept (in this case, b = -1).

A line that is parallel to the given line will have the same slope (m = 2), but a different y-intercept. For example, a line with y-intercept of -2: y = 2x - 2.

So, one equation that could be the other equation of the system and make it inconsistent is y = 2x - 2.
