Step-by-step explanation:

m = - 4/3

y - y1 = m (x - x1)

y - 2 = -4/3 (x - (-5))

3(y -2) = -4(x + 5)

3y - 6 = -4x - 20

3y + 4x = -20 + 6

Answer:

Step-by-step explanation:

1. Convert meters into centimeters:

Nour's structure = 970 cm

Maha's structure = 9.5 meters

1 meter = 100 cm

9.5 · 100 = 950 cm

Result:

Nour's structure: 970 cm

Maha's structure: 950 cm

Nour's structure is 20 cm taller than Maha's structure.

2. Convert meters into centimeters:

Nour's structure: 970 cm + 150 cm = 1120 cm

Maha's structure: 950 cm + 1.05 meters = x

1.05 meters · 100 = 105 cm

Result:

Nour's structure: 970 cm + 150 cm = 1120 cm

Maha's structure: 950 cm + 105 cm = 1055 cm

Nour's structure is 65 cm taller than Maha's structure

A reflex angle is equal to the sum of 180 degreesand any of the primaryangles (acute, right andobtuse angles). Therefore, Reflex angle = 180° + Acute angle.

First, make sure that it is the reflex angle you’re being asked to measure! Lots of children mistakenly, but very carefully measure the wrong angle. Usually, the angle you’re being asked to measure will have a little circle drawn around the point to show you which side needs measuring

2. Make a small mark on your paper to show where 180° is. If you want to, you could even draw a faint line to show the 180° line.

3.You now need to measure the remainder. Using the outside scale on your protractor, measure the angle from the 180° line you have drawn to the second line you have been given (in this case y to x).

4. Add together 180° to the second measurement and this will be your reflex angle.

5. If you want to check your answer, measure the inside angle and check that the two measurements added together equal 360°.

Answer: X=6, Y=4

Step-by-step explanation:

a) The hot air balloon did not violate that air space in both locations.

b) The hot air balloon is 17.678 miles to the west and 17.678 miles to the north from the airport.

c) The crashed hot air balloon violated the airport air space. ([tex]r \approx 8.485\,mi[/tex], [tex]r < 25\,mi[/tex])

a) Polar coordinates of the hot air balloon are described solely by the distance from origin (airport) ([tex]r[/tex]), in miles, and angle in standard position ([tex]\theta[/tex]), in sexagesimal degrees, that is to say:

[tex]z(t) = (r, \theta)[/tex] (1)

Where [tex]t[/tex] is the time, in minutes.

The location of the hot air balloon at both instants is described below:

[tex]z(0) = \left(37.5\,mi, \frac{5\pi}{6}\,rad \right)[/tex], [tex]z(90) = \left(25\,mi, \frac{\pi}{4}\,rad \right)[/tex]

In this case, the hot balloon violates the airport air space if and only if [tex]r < 25\,mi[/tex] and the hot air balloon does not violate that air space in both locations.

b) The equivalent polar coordinates of the hot air balloon in terms of polar components is described by the following formula:

[tex](x,y) = (r\cdot \cos \theta, r\cdot \sin \theta)[/tex] (2)

Where:

If we know that [tex]r = 25\,mi[/tex] and [tex]\theta = \frac{\pi}{4}\,rad[/tex], then the coordinates in rectangular form is:

[tex](x,y) = \left(25\cdot \cos \frac{\pi}{4}, 25\cdot \sin \frac{\pi}{4} \right)\,[mi][/tex]

[tex](x,y) = (17.678, 17.678)\,[mi][/tex]

The hot air balloon is 17.678 miles to the west and 17.678 miles to the north from the airport.

c) The distance of the crashed hot air balloon with respect to origin is determined by Pythagorean theorem: ([tex]x = 6\,mi[/tex], [tex]y = -6\,mi[/tex])

[tex]r = \sqrt{(6\,mi)^{2}+(-6\,mi)^{2}}[/tex]

[tex]r \approx 8.485\,mi[/tex]

Since [tex]r < 25\,mi[/tex], the crashed hot air balloon violated the airport air space.

To measure the height of the kite directly above the ground we will need to know the angle of elevation of the kite on the ground.

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

Given here, the length of the string is 100 feet, and the distance of joe to the projection of the kite is 25 feet. Let the angle of elevation be θ then

cosθ=25/100

cosθ =1/4

θ      = cos⁻¹(1/4)

 θ      = 75.52°

Hence, the other we information required to know is the angle of elevation.

Answer:

x < 9

Step-by-step explanation:

Notice that the sign here is <, not =.

This is an inequality, not an equation.

When you solve an equation, you typically get an answer that x equals a certain number. When you solve an inequality, you typically get an answer that x is greater than a number or x is less than a number, so there are many numbers that are solutions to an inequality.

Let's solve this inequality.

2x + 9 < 27

Subtract 9 from both sides.

2x < 18

Divide both sides by 2.

x < 9

Answer: x < 9

Every number less than 9 is a solution to this inequality.

9 is the correct answer but you put it wrong.

Notice that the sign here is < not =.

Answer:

x < 9

Step-by-step explanation:

Group all constants on the right side of the inequality

2x+9 < 27

Subtract 9 from both sides:

2x+9-9 < 27-9

Simplify the arithmetic:

2x <27 -9

Simplify the arithmetic:

2x < 18

Isolate the x

Divide both sides by2:

[tex]\frac{2x}{2} <\frac{18}{2}[/tex]

Simplify the fraction:

x < [tex]\frac{18}{2}[/tex]

Find the greatest common factor of the numerator and denominator:

[tex]x < \frac{9 *2}{1*2}[/tex]

Factor out and cancel the greatest common factor:
