An equation that has one solution for y for each value of x is referred to be a function. A function pairs each input of a particular type with exactly one output.

The subject of mathematics includes quantities and their variations, equations and related structures, forms and their locations, and places where they can be found. The term "function" refers to the relationship between a set of inputs, each of which has an associated output. A relationship between inputs and outputs in which each input leads to a single, distinct result is known as a function.  Usually, f is used to denote functions (x). input is an x. There are four main types of functions accessible. based on the following factors: on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

Answer:

Let x be the cost of the phone.

we know that the cost of the phone case is 10 times cheaper than the phone so the cost of the case is x/10

We also know that the total cost of the phone and the case is 660.

so we can write an equation:

x + (x/10) = 660

We can solve this equation for x by multiplying both sides by 10:

10x + x = 6600

11x = 6600

x = 600

So the cost of the phone is 600 and the cost of the phone case is 600/10 = 60

Answer: The perimeter of a rectangle is the sum of the lengths of its four sides which is given by the expression: P = 2l + 2w (where l is the length and w is the width)

The expression that does not show this relationship is P = l + w

It doesn't show the relationship because it doesn't take into account the two sides that are equal to the width and the two sides that are equal to the length.

P = 2l + 2w shows the relationship as it considers both length and width of the rectangle twice, once for each pair of sides.

Two or more expressions with an Equal sign is called as Equation.

Given that Mr. Jakarta is having a well built in his backyard.

On Monday 175 feet of the well was drug

Another 165 feet was dug tuesday.

We need to find the how many feet deep was well dug relative to ground level

To find the number of feet, we simply make an addition of the number of feet dug on both days

The total will be 175 feet + 165 feet = 340 feet

The rider has 141 laps left to finish the race.

If a rider has already cycled 4.75 km, and each lap measures 0.25 km, we can determine how many laps the rider has completed by dividing the distance already cycled by the distance per lap.

To find out how many laps the rider has left to finish the race, we will use the information on the total number of laps to complete the race: 160 laps.

The rider has completed:

4.75 km / 0.25 km = 19 laps

The rider has yet to finish:

160 laps - 19 laps = 141 laps

So the rider has 141 laps left to finish the race.

Therefore, the rider has 141 laps left to finish the race.

The blue rectangle is what the rectangle would look like.

The two towns are distance 60 miles apart in the real world if they are 3 inches apart on a map with a scale of 1 inch to 20 miles.

60 miles

1 inch = 20 miles

3 inches = 20 miles x 3 = 60 miles

The scale of a map is a way of expressing the relationship between the distances on the map and the actual distances in the world. If the scale on a map is 1 inch to 20 miles then it means that 1 inch on the map represents 20 miles in the real world. If two towns are 3 inches apart on the map, then this means that the actual distance between them is 3 times the scale, or 3 x 20 miles = 60 miles.

The measure of the sixth angle of the given convex hexagon is 54 degrees.

We know that the sum of all the interior angles of a convex hexagon is:

720 degrees

Given that three interior angles of the given hexagon measure 140 degrees each.

The fourth angle is 84 degrees.

Let us consider the sixth angle to be x degrees.

Then as per the question, the fifth angle is 3 x (sixth angle) = 3x

Hence, sum of all the angles of the given convex hexagon is:

(3 x 140) + 84 + 3x + x = 720

504 + 4x = 720

4x = 720 - 504 = 216

The equation for the nth term of this sequence is  [tex]a_{n}[/tex] = 8n - 14. The solution has been obtained by using the concept of arithmetic progression.  

What is arithmetic progression?

The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same amount. It also goes by the name Arithmetic Sequence.

We are given that the third term is 10.

This means that [tex]a_{3} =10[/tex]

So, n=3

Substituting this value in the given equations, we get

1)  [tex]a_{n}[/tex] = 8*3+10 = 34

2)  [tex]a_{n}[/tex] = 8*3 - 14 = 10  

3)  [tex]a_{n}[/tex] = 16*3+10 = 58

4)  [tex]a_{n}[/tex] = 16*3 - 38 = 10

So, the second and the fourth equation satisfy the condition.

We are also given that the fifth term is 26.

Claim A; This claim is true because If we move a magnet against the magnetic force of a stronger magnet, the motion will make the magnetic field lines to be compressed and this would lead to an increase in potential energy since the magnetic force lines will now be compressed.

Thus, the claim is correct that there is more potential energy that can be stored by moving against the magnetic force of a stronger magnet.

Claim B; Unlike claim A where the magnets were being moved from each other, in this case they are moved closer to each other and therefore this causes a greater compression of space which will lead to a loss in potential energy. Therefore this claim is not true.

Answer: To find the capacity of the tin can, we can use the formula for the volume of a rectangular prism, which is length x width x height. In this case, the length is 5 cm, the width is 4 cm, and the height is 15 cm. So the volume of the tin can is 5 x 4 x 15 = 300 cubic cm.

To find the capacity of the plastic cylinder, we can use the formula for the volume of a cylinder, which is pi x radius squared x height. The diameter of the circular base is 7 cm, so the radius is half of that, or 3.5 cm. So the volume of the plastic cylinder is pi x (3.5 cm)^2 x 10 cm = 385.4 cubic cm.

So the plastic cylinder has a greater capacity by 385.4 - 300 = 85.4 cubic cm.
