Answer:

The speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind) is approximately 2.9 km/h

Step-by-step explanation:

In the question, we have;

The speed of the tailwind = 2 km/h

The time it takes Baba Yaga to the Bald Mountain = 6 hours

The location where Baba Yaga finds her broom = 40 km before Bald Mountain

The duration of the entire journey = 9 hours

Let 'v' represent the speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind), we get;

(v + 2) × t = (v - 2) × (t - 9)

v·t + 2·t = v·t - 9·v - 2·t + 18

2·t = 18 - 9·v - 2·t

4·t = 18 - 9·v

t = 4.5 - 2.25·v

(v + 2) × 6 = (v - 2) × (t - 9) + 40

6·v + 12 = (v - 2) × (4.5 - 2.25·v - 9) + 40

6·v + 12 = (v - 2) × (-2.25·v - 4.5) + 40

With a graphing calculator, we have;

6·v + 12 + 2.5·v² - 0.5·v - 9 - 40 = 0

5·v² + 11·v - 74 = 0

Using the quadratic formula

v = (-11 ± √(11² - 4·5×(-74)))/(2·5)

v ≈ 2.9, or v ≈ -5.1

Therefore;

The speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind), v ≈ 2.9 km/h

Step-by-step explanation:

let y = f(x) and rearrange making x the subject , that is

y = 4x + 3 (subtract 3 from both sides )

y - 3 = 4x ( divide both sides by 4 )

[tex]\frac{y-3}{4}[/tex] = x

Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then

[tex]f^{-1}[/tex] (x) = [tex]\frac{x-3}{4}[/tex] → b

Answer:

37.5

Step-by-step explanation:

180-75 = 105

180 is the sum of all the angle in a triangle

180-105 = 75

75/2 = x becuz the triangle is icoceles

=37/5

Hope this helps :) Giving me brainiest would help a lot :))

The value of x in the triangle shown is 68.

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

We are Given triangle is an isoceles 56=56

Thus, the sum of angles of triangle is 180.

X+56+56=180

X=180-112

X=68

Therefore, the value is X is 68.

Step-by-step explanation:

Answer: See explanation

Step-by-step explanation:

We are informed that Ahmad averaged 12 km/h in the first 2 hours. Total distance for the first 2 hours = 12km × 2 = 24km.

In the next three hours he averaged 8 km/h. The total distance for the next 3 hours = 8km × 3 = 24 km

A) Calculate the total distance covered.

This will be the distance covered for the 5 hours. This will be:

= 24km + 24km

B. Calculate his average speed for the whole journey.

This will be:

= Total distance covered / Total time taken

= 48km / 5

= 9.6 km/hour

well i be smart my friend XD

1 + 1 (13 - 1 * 15) + 123 (23 / 4)

1 + 1 * - 2 + 123 x 5.75

1 - 2 + 707.25

-1 + 707.25

706.25

Answer:

Step-by-step explanation:

1 × 1(13 - 1 × 15) + 123 × (23/4) = 1 × 1(13 - 15) + 123 × (23/4)

= 1 × 1(-2) + 123 × (23/4)

= 1 × (-2) + 123 × (23/4)

= 1 × (-2) + 123 × (5.75)

= -2 + 123 × (5.75)

= -2 + 707.25

Answer:

line k:  y = x + 4

line m:  y = -2x + 4

line p:  y = -6

line r:  x = 1

Step-by-step explanation:

The equation for each line considering the graph is line k:  y = x + 4, line m:  y = -2x + 4, line p:  y = -6, line r:  x = 1

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Calculate the slopes of the lines as shown below,

[tex]m = y_2 - y_1 / x_2 - x_1[/tex]

For line k, m = 0 - (-4) / -4 -0

m = -1

Thus, the equation of a line having slope -1 and coordinates (0, 4) can be written as,

[tex]y-y_1 = m(x- x_1 )[/tex]

y - 4 = -1(x-0)

y -4 = -x

y = -x + 4

Similarly, write the equation for lines m, p, and r,

line m:  y = -2x + 4

line p:  y = -6

line r:  x = 1

Step-by-step explanation:

The origional question is ¨A turtle travels 1/2 mile in 1/9 hour. At this rate, how far can the turtle travel in an hour¨ To be honest i have no clue how to explain it but that is the awanser.

The turtle will travel  [tex]4\frac{1}{2}[/tex] in an hour.

A proportion is an equation in which two ratios are set equal to each other.

Given that, a turtle travels 1/2 mile in 1/9 hour. we need to find, at this rate, how far can the turtle travel in an hour.

We will solve this by using proportionality, since, rate is constant,

Let the turtle travels x miles in an hour,

Therefore,

x / 1 = (1/2) / (1/9)

x = 1/2 × 9

x = 9/2

x = [tex]4\frac{1}{2}[/tex]

Hence, the turtle will travel  [tex]4\frac{1}{2}[/tex] in an hour.
