Answer:
(-4, 3)
Step-by-step explanation:
From the graph, it looks like the two lines intersect at pint (-4, 3).
3/5(15d+20)−1/6(18d−12)=38
Simplify
3/5(15d+20)−1/6(18d−12)=38
(3/5)(15d)+(3/5)(20)+−3d+2=38(Distribute)
9d+12+−3d+2=38
(9d+−3d)+(12+2)=38(Combine Like Terms)
6d+14=38
Subtract 14 from both sides.
6d+14−14=38−14
6d=24
Divide both sides by 6.
6d/6 = 24/6
d=4
Answer:
Please check the explanation.
Step-by-step explanation:
Given
The angle Ф = 42°
The hypotenuse = 15 cm
To determine
The length AB = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
In our case:
- The adjacent to the angle Ф = 42° is the side AB
so substituting Ф = 42°, adjacent = AB, hypotenuse 15 in the trigonometric ratio
cos Ф = adjacent / hypotenuse
cos 42° = AB / 15
AB = 15 × cos 42°
AB = 11.14 cm
Therefore, the length of the side AB = 11.14 cm

Answer:
cot(θ) = 4/5
Step-by-step explanation:
In the polar/rectangular coordinate representation (x, y) ⇔ (r; θ), we know that ...
(x, y) = (r·cos(θ), r·sin(θ))
From the various trig definitions and identities, we also know that ...
cot(θ) = cos(θ)/sin(θ) = (x/r)/(y/r) = x/y
For the given (x, y) = (-4, -5), the cotangent is ...
cot(θ) = -4/-5 = 4/5
