Answer:
Step-by-step explanation:
(A) Since, the velocity can be calculated from the distance time graph, and we can see from the graph that it is constant at every point, thus the graph has the constant velocity.
(B) Average velocity is given by:
.
(C) The velocity reflected in the graph is positive in nature.
(D) The point will show that the car is not moving means that the car will cover no more distance in any interval of time, but from the graph we can see that the distance is being covered at equal intervals of time and no such horizontal path is followed, thus, the car is always moving.
Formula of surface area of a sphere is 4
![\pi r^{2}](https://tex.z-dn.net/?f=%20%5Cpi%20r%5E%7B2%7D%20)
.
Hence it is 4
Answer:
The answer to your question is letter A. 18 ft
Step-by-step explanation:
Data
Man height = 6 ft
distance from the lamppost to the man = 8 ft
shadow = 4 ft
height of the lamppost = x
Process
1.- Use proportions to use this problem
![\frac{height of the lamppost }{height of the man} = \frac{length of the lamppost to the shadow}{length of the man to the shadow}](https://tex.z-dn.net/?f=%5Cfrac%7Bheight%20of%20the%20lamppost%20%7D%7Bheight%20of%20the%20man%7D%20%3D%20%5Cfrac%7Blength%20of%20the%20lamppost%20to%20the%20shadow%7D%7Blength%20of%20the%20man%20to%20the%20shadow%7D)
![\frac{x}{6} = \frac{12}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B6%7D%20%3D%20%5Cfrac%7B12%7D%7B4%7D)
2.- Solve for x
![x = \frac{6 x 12 }{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%20x%2012%20%7D%7B4%7D)
3.- Simplifying and result
x = 18 ft
What you need to do step 1 y=6-7
step 2 y=1
then you make an ordered pair with the x and y
then graph
Answer:
$12/hr
Step-by-step explanation:
48 is for 4 hours so for 1 hour you divide by 4
48/4=12
