17. Which of the following trigonometric functions can be described as a reciprocal trig function?
Nataly [62]

Answer:

Step-by-step explanation:

Reciprocal trig functions are opposite or mirror of the normal trig functions. The normal trig functions are as follows:

Sine = opposite side/hypotenuse

Cosine = adjacent side/hypotenuse

Tangent = opposite side/adjacent side

The reciprocals of the above trig ratios would be

Cosecant = hypotenuse/opposite side

Secant = hypotenuse/adjacent side

Cotangent = adjacent side/opposite side

Therefore, looking at the given options, the trigonometric function that can be described as a reciprocal trig function is

If Rahul walks 9km in a week and Vansh walks 900 m daily, which of these is true about the distances they cover in a week?
pantera1 [17]

Answer: Rahul walks 2.7 km more than Vansh.

Step-by-step explanation:

The options include:

a. Vansh walks 7.2 km more than Rahul.

b. Vansh walks 2 km more than Rahul.

c. Rahul and Vansh both cover the same distance.

d. Rahul walks 2.7 km more than Vansh.​

Distance covered by Rahul weekly = 9km

Distance covered by Vansh weekly = 900m × 7 = 6300m = 6300/1000 = 6.3km

From the above, we can see that Rahul walk (9km - 6.3km) = 2.7km more than Vansh.

Note: 1000 meters = 1 kilometers
