The difference of two squares is a theorem that tells us if a quadratic equation can be written as a product of two binomials, in which one shows the difference of the square roots and the other shows the sum of the square roots, the difference of two squares is a squared (multiplied by itself) number subtracted from another squared number.  This identity is often used in algebra where it is useful in applications to integer factorization, the quadratic sieve, the algebraic factorization, etc.

One thing to note about this theorem is that it does not apply to the SUM of squares.

An example of discontinuous change is an adolescent experiencing puberty.

The term "discontinuity" is used in the literature on behaviour in a number of distinct contexts. It should specifically relate to a rapid change in a system's properties.

A discontinuity is stated to have happened when a two-month-old human infant's attention, vocalisation, and sniffing scores do not predict their scores on the same test at four months. "Discontinuity" is also used to describe the rearrangement of rank on a specific measure.

The first twenty years of a person's life are when discontinuous change is most noticeable, such as during birth and puberty. These gaps in continuity are not puzzling. Many biological and physical systems have the capacity to change abruptly and discontinuously.

Applying the triangle midsegment theorem, the length of segment TU = 100 units.

If a line connects the midpoints of two sides of a triangle, it is parallel to the third side, and according to the triangle midsegment theorem, it has a length that is half the measure of the third side of that triangle.

Given the triangle, TUV, where:

Segment TU is a third side to the midsegment HD = 50 units.

Thus, apply the triangle midsegment theorem to find the length of segment TU.

HD = 1/2(TU)

Yes, a hole is considered an asymptote.

There are "holes" in the graph called vertical asymptotes where the function cannot have a value. They represent areas where the x-value is not permitted.

Answer:

B

Step-by-step explanation:

A = 0.5kg (Not close)

B = 0.05

C = 0.02 ( Not close)

D = 0.04

(Explanation why answer is B and not D)

B is closet because even we round off to two decimal places 0.05kg answer comes not 0.04kg

Plus 0.05 is 0.01kg away from 0.049, While 0.04kg is 0.09kg away from 0.049kg.

I hope my answer helps you.

1/20 kg is closest to 0.049 kg among the given choices. So, correct option is B.

To determine which option is closest to 0.049 kg, we can compare the given options to the target value and find the option with the smallest absolute difference.

A. ½ kg = 0.5 kg (Difference = |0.5 kg - 0.049 kg| ≈ 0.451 kg)

B. 1/20 kg = 0.05 kg (Difference = |0.05 kg - 0.049 kg| = 0.001 kg)

C. 1/50 kg = 0.02 kg (Difference = |0.02 kg - 0.049 kg| ≈ 0.029 kg)

D. 2/50 kg = 0.04 kg (Difference = |0.04 kg - 0.049 kg| = 0.009 kg)

Comparing the absolute differences, we can see that option B (1/20 kg = 0.05 kg) has the smallest difference from 0.049 kg, which is only 0.001 kg.

Therefore, option B (1/20 kg) is closest to 0.049 kg among the given choices.

When dealing with questions like this, it is helpful to compare the values using the absolute difference from the target value. The option with the smallest absolute difference is the closest approximation to the target value. In this case, 1/20 kg provides the closest value to 0.049 kg, making it the correct choice.

add their velocities

422+384= 806

now divide 6045 by 806 = 7.5  or  7 hours 30 minutes

7:30 = t   hours:minutes

Part 2)

For this part we will need to employ Pythagoras theorem. we need the hypotenuse to be 1,997

so, when will  plane traveling N ,  and plane traveling W be that far (1997)?

or

when does  [tex]1997^{2}[/tex] = [tex]N^{2}[/tex] + [tex]W^{2}[/tex]

then we're also given that  N = 422*t

and  that  W = 384 * t

so now our formula looks like

[tex]1997^{2}[/tex]  = [tex](422*t)^{2}[/tex] + [tex](384*t)^{2}[/tex]

rewrite this so it's making clear math sense

[tex]1997^{2}[/tex]  = [tex]422^{2}[/tex] * [tex]t^{2}[/tex] + [tex]384^{2}[/tex] * [tex]t^{2}[/tex]

now pull out the [tex]t^{2}[/tex]

[tex]1997^{2}[/tex]  = ( [tex]422^{2}[/tex]  +   [tex]384^{2}[/tex] ) * [tex]t^{2}[/tex]

now simplify some

3988009 = (178084 + 147456 ) * [tex]t^{2}[/tex]

now divide the left side by the numbers on the right

3988009 /  (178084 + 147456 )  = [tex]t^{2}[/tex]

12.12044234 = [tex]t^{2}[/tex]

[tex]\sqrt{12.25044234}[/tex] = t

3.500063191 = t
