Answer:
2m/s² ; - 2m/s²
25m ; 50m ; 25m
6.67 m/s²
Step-by-step explanation:
The acceleration and deceleration :
Both rates are the Same from the graph ;
According to scenario described, acceleration = 2m/s²
Deceleration occurred in equal time interval = - 2m/s
Distance covered during each stage:
Stage 1 : area of triangle
0.5 * base * height
0.5 * 5 * 10 =25 m
Stage 2: area of rectangle :
Length * breadth = 5 * 10 = 50 m
Stage 3 : area of triangle
0.5 * base * height
0.5 * 5 * 10 =25 m
Average Velocity :
Total distance / time = (25 + 50 + 25) / 15 = 100/ 15 = 6. 67 m/s
Answer:
Step-by-step explanation:
step 1
Find out the price of 160 begonias, if she bought them separately
step 2
Find out the price of 160 begonias, if she bought them by the flat
Remember that
One flat are 20 plants
so
For 160 plants are needed
160/20=8 flat
step 3
Find out the difference
Answer:
8
Step-by-step explanation:
compare the divisor x+1 with x-a which will be -1 then use remainder theorem to get your answer
