The average speed during the two seconds in which the runner moved from 15 meters from the finish line to 3 meters past the finish line is 9 m/s

The average speed of the runner can be determined by using the following formula;

speed = distance ÷ time

As she moved from 15 meters from the finish line to 3 meters past the finish line in 2 seconds, the total distance covered in these 2 seconds by her can be calculated as follows;

distance = 15 meters + 3 meters

distance = 18 meters

Now substituting the values for distance and time in the formula;

speed = 18 / 2

speed = 9 m/s

Hence the average speed of the runner during the two seconds is calculated to be 9 m/s.

A maximum of 105 number of 120 kilograms can be loaded in the container.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Weight of each crate = 120 kg

The greatest weight loaded in the container = 27500 kg

Weight already loaded in the container = 14900 kg

Now,

Since, Weight already loaded = 14900 kg

Let number of 120 kilograms loaded in the container = x.

Hence, Weight of x = 120 kg

So, After combined we get;

Weight nor be greater than the capacity of the container.

Hence, we can formulate;

14900 + 120x ≤ 27500

Subtract 14900 we get;

120x ≤ 27500 - 14900

120x ≤ 12600

x ≤ 12600 ÷ 120

x ≤ 105

Thus, A maximum of 105 number of 120 kilograms can be loaded in the container.

Step-by-step explanation:

ok

Answer:

E. 4x - 1

Explanation:

An equation that represents the table satisfies that when we replace each value of x in the table, we get its respective value of y in the table.

So, the answer is:

y = 4x - 1

Because:

For x = -2, we get:

y = 4(-2) - 1

y = -8 - 1

y = -9

For x = -1, we get:

y = 4(-1) - 1

y = -4 - 1

y = -5

For x = 1:

y = 4(1) - 1

y = 4 - 1

y = 3

For x = 2:

y = 4(2) - 1

y = 8 - 1

y = 7

Henry can write 13 pages in 8 hours, at this rate.

This is a problem from the unitary method. We can solve this question following a few steps.

Here if Henry can write 5 pages of his novel in 3 hours. We have to find the number of pages that Henry can write within 1 hour.

The number of pages Henry can write within 1 hour is 5/3 pages.

[Number of pages within a unit hour = number of total pages/ total hour]

Therefore, Henry writes in 8 hours is, ( 5/3 × 8 ) = 40/3 = 13.33 ≈ 13 pages

The function is f(x) = 1/3(27)ˣ, the key aspects are domain: -oo < x < oo and range: y ≥ 1/3

From the question, the equation of the function is given as

f (x) = one-third (81) Superscript StartFraction 3 x Over 4 EndFraction

Rewrite the equation properly

So, we have

f(x) = 1/3(81)³/⁴ˣ

Express 81 as 3 exponent 4

So, we have the following equation

f(x) = 1/3(3⁴)³/⁴ˣ

Evaluate the exponents

f(x) = 1/3(3)³ˣ

Further, evaluate the exponents

f(x) = 1/3(27)ˣ

Next, we calculate the key aspects i.e. the domain and the range

The above function is an exponential function.

The domain of an exponent is the set of all real values

Set the radicand to 1, to calculate the range

So, we have

y = 1/3 * 1

Evaluate

y = 1/3

Since the coefficient, this value is a minimum

So, the range is

y ≥ 1/3

Hence, the simplified function is f(x) = 1/3(27)ˣ

Answer:

Step-by-step explanation:

Given isosceles trapezoid MNFD with short base NF = 6 cm, diagonal ND perpendicular to leg MN, and triangle MND median NX = 5 cm, you want ...

MD is the hypotenuse of right triangle MND. The median from the right angle of a right triangle is half the length of the hypotenuse, so ...

  MD = 2·NX = 2·(5 cm)

  MD = 10 cm

In the attached diagram, we see that right triangle XYN has side XY = 3 (half of NF), and hypotenuse NX = 5 (given). These are two sides of a 3-4-5 right triangle, so the remaining side, altitude h, is 4.

  h = 4 cm

The attache diagram shows congruent side lengths MN and FD are the hypotenuse of a right triangle with sides YM = 2 and YN = 4. The Pythagorean theorem tells us the length of side MN is ...

  MN² = MY² +NY²

  MN² = 2² +4² = 4 +16 = 20

  MN = √20

  MN = FD = 2√5 ≈ 4.47

Triangle MND has a base length MD = 10 and a height h = 4. Triangle NFD has a base length NF = 6 and a height h = 4. The ratio of the areas of these two triangles is ...

  [tex]\dfrac{A_{MND}}{A_{NFD}}=\dfrac{\frac{1}{2}\cdot10\cdot4}{\frac{1}{2}\cdot6\cdot4}=\dfrac{10}{6}=\boxed{\dfrac{5}{3}}[/tex]

The ratio between the areas is 5 : 3.

__

Additional comment

We are also given the area of the trapezoid as 32 cm². That can be used to find the longer base and/or the altitude, or to check the answers we have for those values. It is redundant information.

The midpoint X of MD is the center of the circumscribing circle of the trapezoid and right triangles MND and MFD. The midpoint of the hypotenuse of a right triangle is always the circumcenter, so knowing the length NX tells us the radius of that circle, hence MX and XD.

Since the diagonal is less than the circle's diameter, the Pythagorean theorem reveals that the square may fit within the circle without touching its edge.

Since squares are made up of two right triangles of equal length, the Pythagorean theorem is used to calculate the length of the hypotenuse of right triangles, which corresponds to the diagonals in squares.

The diagonal (L) of the square must be less than the diameter of the circle if it can fit within the circle without touching the edge (d). Therefore, we continue to establish this connection:

[tex]L=\sqrt{2}.5cm[/tex]

L ≈ 7.071 cm
