Answer:
v = 33.8 m/s
Step-by-step explanation:
Given that,
The initial velocity of the truck, u = 0
Acceleration of the truck, a = 3.6 m/s²
Time, t = 9.4 s
We need to find the car's final velocity. Let v is the final velocity.
Using equation of kinematics as follows :
v = u +at
Since, u = 0
Hence, the final velocity of the car is 33.8 m/s.
Answer:
(4,2) (2,8)
Step-by-step explanation:
The percent of time the photographer spent negotiating with the bison greater than the time he spent taking pictures is 500%
<h3>Percentage</h3>
- Time spent taking pictures = 5 minutes
- Time spent negotiating = 30 minutes
Percentage of time negotiating greater than taking pictures = (difference in time) / time to take pictures × 100
= (30 - 5) / 5 × 100
= 25/5 × 100
= 5 × 100
= 500%

Step-by-step explanation:
substitute 2 into x
1. (u ○ w)(2)
u(w(x))
= 4(-5x+1)+2
= 4(-5.2+1)+2
= 4(-9)+2
=-34
2. (w ○ u)(2)
w(u(x))
= -5(4x+2)+1
= -5(4.2+2)+1
= -5(10)+1
= -49
