Answer:
-∞ < x < 0
Step-by-step explanation:
The domain is the horizontal extent of the graph.
The arrow at upper left means the graph extends to infinity upward and to the left.
The open circle on the y-axis means the value x=0 is not included in the domain.
So, the graph extends from -∞ to as close to zero as you like:
domain: -∞ < x < 0

Solve for q plz help question is in pic
Answers
Answer:
(p, q) = (4/10, 15/10) = (0.4, 1.5)
Step-by-step explanation:
Apparently, you're to solve for q first. It is convenient to use the first equation for that purpose.
-4p +7q = 89/10
7q = 89/10 +4p . . . . . . add 4p to both sides
q = (89/10 +4p)/7 . . . . divide by the coefficient of q
Now, we have an expression we can substitute for q in the second equation:
-12p +35(89/10 +4p)/7 = 477/10
-12p +445/10 +20p = 477/10 . . . . . eliminate parentheses
8p = 32/10 . . . . . . . . . . . . . . . . subtract 445/10
p = 4/10 . . . . . . . . . . . . . . divide by 8
q = (89/10 +4(4/10))/7 = 105/(10·7) = 15/10
The solution is (p, q) = (0.4, 1.5).

Answers
Answer:
Explained Below
Step-by-step explanation:
first we need to turn the equation into point slope form.
3x + 4y = 12
4y = -3x + 12
y = -0.75 + 3
Parallel lines don't have a change in slope because they run parallel. Your answer would be -0.75 or -3/4.

miles south: ______
miles west: ______
(b) At 6:00 P.M., the ship changes course to due west. Find the ship's bearing and distance from port at 7:00 P.M. (Round your answers to one decimal place.)
S______° W
_______nautical miles
Answers
Answer:
(a) 101.77 mi S; 63.59 mi W
(b) S 39.4° W; 131.7 nautical miles
Step-by-step explanation:
(a)In the 6 hours from noon until 6 pm, the ship will have traveled a distance of ...
distance = speed × time
distance = (20 nm/h) × (6 h) = 120 nm . . . . . . using "nm" for nautical miles
In (S, W) coordinates, the location of the ship will be ...
120(cos(32°), sin(32°)) ≈ 120(0.848048, 0.529919) ≈ (101.77, 63.59)
The ship will have traveled 101.77 miles south and 63.59 miles west.
__
(b)In the 1 hour from 6 pm to 7 pm, the ship will have traveled an additional 20 miles west. In (S, W) coordinates, its location at 7 pm is (101.77, 83.59). The distance from port will be ...
d = √(101.77² +83.59²) ≈ 131.7 . . . nautical miles
The direction from the port is ...
arctan(83.59/101.77) ≈ 39.4°
The bearing and distance are ...
S 39.4° W131.7 nautical miles_____
Additional comment
The math for bearings and distances works the same for any consistent set of reference directions and angles. Here, all of the points of interest are in the 3rd quadrant of the Cartesian plane. The given angle is measured CW from south. It is convenient to use (south, west) coordinates so that we can use the distance and angle measures directly, without having to translate to (x, y) coordinates.
If bearings are given as angles CW from north, then it is convenient to use (N, E) coordinates.

Answer:
Step-by-step explanation:
first of all , find the value of x :
Remember that circles have a 360 º angle in total so what you have to do is add the angles that you have and subtract them by the total that is 360 .
50º+77º+115º+x =360º
242º+x=360º
x=118º
now that you have the value of x , the only thing that you have to do is to look the angle that they asking you to put .
i)
∠AOB =50º
ii)
∠BOC =77º
iii)
∠COD=115
