Which line has a y-intercept of -5?
A 12x + 5y = 0
B 5x + 12y = -60
C 5x - 12y = 25
D 12x - 5y = -60
Answer:
B)
Step-by-step explanation:
You would have to divide the number multiplying y on both sides to find the y-intercept. Only in B, -60/12= -5.

Answer:
40
Step-by-step explanation:
2 of 5 slots are shaded in, so that would be 2/5.

A hot air balloon appears as a blip on the air traffic controller’s radar screen. Hot air balloons are prohibited from flying within 25 miles radius of the airport. The polar grid shows the air traffic controller tracking the hot air balloon. (Radius = 10 miles) The grid shows the location of the hot air balloon at time t =0 minutes (when it first appeared on the radar screen) and time t=90 minutes later.
Express the two locations of the hot air balloon in polar coordinates. Is the hot air balloon in violation of the airport air space at either of these locations? Explain. (2 points)
Determine the rectangular coordinates of the hot air balloon at time t = 90 minutes. State the meaning of this answer in the context of the problem. (3 points)
The hot air balloon crashes 6 miles east and south of the air traffic controller’s tower. Determine the distance the balloon is from the control tower and if it has violated the airport air space. Justify your answer. (3 points)
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:
[tex]x[/tex] - Horizontal distance with respect to origin, in miles.[tex]y[/tex] - Vertical distance with respect to origin, in miles.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.

find the reflex angle 150 degrees ?
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:
Nour's structureNour's structureStep-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

Which line is parallel to the line whose equation is 4x + 3y = 7 and also passes through the point (-5,2) ?
A. 4x + 3y = -26
B. 4x + 3y = -14
C. 3x + 4y = -7
D. 3x + 4y = 14
Answer:
B
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
4x + 3y = -14

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.
What is the angle of elevation?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.
