For this distance-time graph, what is the velocity of the car?
1 answer:
Answer:
Vel. of the car = 3.33 meter per second.
Explanation:
In given graph, y axis represent the distance traveled by the car and x axis represent the time taken by car.
At time t = 30 seconds , distance traveled by the car is 100 meter
We know that,
Speed =
speed =
speed = 3.33 meter per second
That's the final answer.
I hope it wil help you.

Answer:
The expression of h as function of x is h =
Step-by-step explanation:
Given as :
The distance of blimp (AB) = 5500 feet
The slanted distance to the pagoda (BC) = d feet
The horizontal distance (AC) = h
Let the angle made between slanted distance and horizontal distance be Ф
So , cos Ф = =
And sin Ф = =
∵, cos²Ф = 1 - sin²Ф
So, =
Or, =
Or, h² = d² - 5500²
∴ h =
Or, h =
Hence The expression of h as function of x is h = Answer
