Answer:

Step-by-step explanation:

Two angles are called complementary when their sum is 90º. In the figure, the α and β angles together form a right angle. Two angles are called supplementary when their sum is 180º. In the figure, the α and β angles together form a straight angle.

What is the domain of y=cot x?

MissTica

We have to find the domain of y = cotx

We know that cotx = cos x / sinx

And also when sinx becomes zero cotx becomes undefined

And again we know that value of cosx and sinx can be between -1 to 1

But value of cotx can lie in between -∞ to +∞

Just for example cot30 is cos30 / sin30

= √3/2/1/2 = √3

Therefore domain of cotx is x

x ∈ R , x ≠ πn for any integer n

Flying against the wind, a jet travels 4400mi in 8 hours. Flying with the wind, the same jet travels 5820mi in 6 hours. What is

Anna [14]

<span>distance=6390km; time=9 hrs; rate=710kph
With the wind Data:
distance=5150km; time=5hrs; rate=1030kph
EQUATIONS:

airspeed+jetstream=1030
airspeed-jetstream=710
Subtract these equations to get:
2jetstream=320kph
jetstream=160mph </span>

How far, D, does a vehicle travel if it is moving at a rate, r, of 60 km/h and it travels for t =150 minutes? Use the formula D=

strojnjashka [21]

The distance of a vehicle travel is 150 km, at a moving rate of 60 km/h for 150 minutes.

Step-by-step explanation:

The given is,

Moving rate, r = 60 km/h

Time, t = 150 minutes

Step:1

We need to find the distance traveled by the vehicle,

From given the formula is

D = rt

Where,

D = Distance in Km

r = Moving rate in Km/h

t = Time in hours

Step:2

We need to convert the time minutes to hours

t = $\frac{150}{60}$ hours

t = 2.5 hours

Step:3

Distance traveled by the vehicle is,

D = 60 × 2.5

= 150

D = 150 Km

Result:

The distance traveled by the vehicle is 150 Km at a moving rate of 60 km/h for 150 minutes.
