Part 1: Determine the limits of a function given a graph

Answers

The value of limits and function values for a, b, c, d, e, f, g, h, i, and j are 3, -1, does not exist, 3, 1, 2, does not exist, 2 +∞, and -∞ and doesn't follow continuity conditions and its jump continuity.

What is the limit?

A limit is a value at which a function approaches the output for the given values in mathematics. Limits are used to determine integrals, derivatives, and continuity in calculus and mathematics.

We have a graph of a function:

For [tex]\lim_{x \to -1^{-1}} f(x)[/tex]

As we can see x approaches -1 and it is a left-hand limit.

[tex]\lim_{x \to -1^{-1}} f(x) = 3[/tex]

For [tex]\lim_{x \to -1^{+1}} f(x)[/tex]

The x approaches the +1 and it is the right-hand limit.

[tex]\lim_{x \to -1^{+1}} f(x) = -1[/tex]

For [tex]\lim_{x \to -1} f(x)[/tex]

Since the left hand and right-hand limits are not the same,

[tex]\lim_{x \to -1^{+1}} f(x)[/tex]  = does not exist

From the graph:

f(-1) = 3

Similarly, we can find further values of the limits and functions value:

[tex]\lim_{x \to 2^{-1}} f(x) = 1[/tex]

[tex]\lim_{x \to 2^{+1}} f(x) = 2[/tex]

For [tex]\lim_{x \to 2^{}} f(x)[/tex]

Since the left hand and right-hand limits are not the same,

[tex]\lim_{x \to 2^{}} f(x)[/tex] = does not exist

f(2) = 2

[tex]\lim_{x \to -\infty} f(x) = +\infty[/tex]

[tex]\lim_{x \to +\infty} f(x) = -\infty[/tex]

There are three conditions a graph must follow:

1) function value defined at any given point.

2) left-hand limit and right-hand limit must be equal

3) function value at the point and limit value at the same point must be the same.

In the given function the graph doesn't follow these conditions and its jump continuity.

Thus, the value of limits and function values for a, b, c, d, e, f, g, h, i, and j are 3, -1, does not exist, 3, 1, 2, does not exist, 2 +∞, and -∞ and doesn't follow continuity conditions and its jump continuity.

A box is 36 inches long 18 inches wide and 6 inches deep. How many cubic feet are in the box?

Answers

The amount of cubic feet in the box = volume = 2.25 cubic feet.

What is the Volume of a Box?

Volume of a box is the amount of cubic feet in the box which is calculated as: V = (length)(width)(height).

Given the following:

Length = 36 inchesWidth = 18 inchesHeight = 6 inches

Volume = (36)(18)(6)

Volume = 3,888 cubic inches.

Convert to 3,888 cu. in. to cu. ft. [1 cu. ft. = 1728 cu. in.]

Answers

The angle of inscribed polygon m∠MNT from the triangle ABC is 45°

What is an inscribed polygon?

An inscribed polygon is a polygon whose vertices lie on the circle and the circle inscribing the polygon is known to be a circumscribed circle. But let's not forget that the circle is also inscribed in another right-angle triangle.

However, using the inscribed right angle theorem:

Supposed that a right triangle is inscribed in a circle;

We can infer that the hypotenuse is the diameter of the circle.

From the given image, line MN is the diameter of the circle since that is the only diameter in the circle.

And the angle facing the diameter is the right angle. i.e ∠T = 90°

We know that the sum of angles in a triangle is 180°. So, if ∠T = 90°, ∠N and ∠M = x

i.e.

90° + x + x = 180°

90° + 2x = 180°

2x = 180° - 90°

2x = 90°

x = 90°

x = 45°

Therefore, we can conclude that angle m∠MNT = 45°

The cost of the car rental is 27.99 with unlimited miles, but the cost of the rental is 42% higher on Saturday and Sunday. The company charges a $40 fee for renters younger than 25 . How much will it cost John to rent the car?

Answers

Answer:

109.99 $

Step-by-step explanation:

add or maybe multiply the numbers that have to do with money: 27.99 + 42 + 40

It will cost $107.74 for John to rent a car.

What is addition?

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

John is 23 years old and rents a car for 4 days, from Thursday through Sunday.

The cost of the car rental is 27.99 with unlimited miles,

but the cost of the rental is 42% higher on Saturday and Sunday.

The company charges a $40 fee for renters younger than 25.

The total cost,

= 27.99 + 40 + 27.99 x 1.42

= $107.74

Therefore, the cost is $107.74.

When the shadow of a flagpole is 36 m long, a 1.8-m fencepost casts a shadow that is 3 m long. How tall is the flagpole?

Answers

Answer:

21.6 m long

Step-by-step explanation:

To do this, we find the scale factor of the fencepost and the shadow.

3/1.8 = 1.66666667

So, we know that when we take the original length and multiply it, we get the new one, so:

1.666666667 * x = 36

x being the original length. Now, we divide both sides by 1.66666667 to get x alone and find the original length.

x = 21.6

To double check, we can take the scale factor and multiply it by the original to get the shadow.

21.6 * 1.666666667 = 36

It is correct

Answers

I would say the mean because there are no clear outliers.

For the given data set 31, 32, 31, 34, 30, 30, 31, 31, 30, 31, median is the  best measure of the center.

The given data set is 31, 32, 31, 34, 30, 30, 31, 31, 30, 31.

In this data set, the best measure of the center would likely be the median.

The data set is relatively small and seems to have a repeated value (30), which could potentially skew the mean.

The median, on the other hand, would provide a more representative measure of the central tendency as it is not affected by outliers or repeated values as much as the mean or mode.

Hence, median is the  best measure of the center for the data set.
