A man jogs at a velocity of 2.5 m/s west for 1,200 s. He then walks at a velocity of 1.0 m/s east for 500 s and then stops to re

Vinvika [58]

Answer:

The displacement is 2500 m towards west.

Step-by-step explanation:

Taking west as negative direction and east as positive direction.

Velocity of man jogging west = -2.5 m/s

Time he traveled towards west = 1,200 s

Displacement in west direction = $Velcoty \times time=-2.5\ m/s\times 1200\ s=-3000\ m$

Velocity of man jogging east = 1.0 m/s

Time he traveled towards east = 500 s

Displacement in west direction = $Velcoty \times time=1.0\ m/s\times 500\ s=500\ m$

Total displacement can be calculated by finding the sum of displacement.

Total displacement = $-3000\ m+500\ m=-2500\ m$

Since, the resultant displacement is negative, so the displacement is 2500 m towards west.

If h(x) = -3x - 10, find h(-3). Answer -1 2.3 -19 1 ...?

lara31 [8.8K]

The correct answer is: [A]: " - 1 " .
__________________________________________________________
Explanation:
__________________________________________________________
Given: " If h(x) = -3x − 10, find h(-3). "

So; we plug in "-3" for all values of "x" ; to solve for " h(-3)" ; as follows:

→ h(-3) = -3(-3) − 10 = 9 − 10 = - 1 .

The answer is: " - 1 " .
