Aria walked down a trail into a valley. V(d) models Aria's vertical distance from the top of the valley (in kilometers) after wa
Snezhnost [94]

Answer: It means Aria's vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.

Step-by-step explanation:

Since, Here d represents distance along the trail.

And, V(d) represents the vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.

If the distance along the trial is 3 km.

That is, d = 3

Then the vertical distance she walked from the top of the valley = V(3)

But According to the question,

V(3) < 3

Her vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.

In other words, For going 3 km along the trail her vertical distance from the top of the valley is less than 3.

Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand. In the first part of the race, her av
algol [13]
First part of the race

speed1, s1 = 8.75 km/h
distance1 = 5 km - x
time 1 = 0.65 h - t 

Second part of the race

speed2, s2 = 6 km/h
distance2 = x
time2 = t

s2 = x/t = 6 ⇒ t = x / 6

s1 = [5 - x] / [0.65 - t] = 8.75

5 - x = 8.75 [0.65 - t]

5 -x = 8.75(0.65) - 8.75t

5 - x = 5.6875 - 8.75 (x/6)

5 - x = 5.6875 - 1.4583x

1.4583 x - x = 5.6875 - 5

0.4583 x = 0.6875

x = 0.6875 / 0.4583 = 1.5

Write the direction cosines of the vector -21-5k​
AlekseyPX

Answer:

a=-2î+j-5k

|a| = √(−2)² +1² + (−5)²

a = √√4+1+25

a = √30

Thus, direction cosines of a are

(- 2/(sqrt(30)), 1/(sqrt(30)), - 5/(sqrt(30)))
