Answer:
45km
Step-by-step explanation:
Given data
Average Speed= 15km/h
Time = 3 hours
Required
The distance traveled
Speed= distance/time
Distance= speed*time
Distance= 15*3
Distance= 45km
Hence the lower bound of the distance is 45km
Answer:
1
Explanation:
Radius = C/2π
C is 6.28 and 2*pi is also 6.28
So 6.28/6.28 = 1.

Step-by-step explanation:
Answer:
x⁴ + 3x³ - 5x + 1
Step-by-step explanation:
(x - 1)(x³ + 4x² + 4x - 1)
Same as writing....
x(x³ + 4x² + 4x - 1) - 1(x³ + 4x² + 4x - 1)
x⁴ + 4x³ + 4x² - x - x³ - 4x²- 4x + 1
x⁴ + 3x³ - 5x + 1
