3 because it’s the middle number 1222(3)5788 hope I helped u out
Answer:
a is 840 ,b is 525
Step-by-step explanation:
At the end of each year, its value is down to 79%, which is 0.79 times its value at the start of the year. Keep this up for n years and the value is
V(n) = $20,000 (0.79)n,
where n is the number of years elapsed from when the value was $20,000. Just plug in n=5 and n=8, evaluate, and get your 2 answers.
Answer:
5.625 m/s²
Step-by-step explanation:
Intial velocity of car, u = 54 km/h = 54 × 5/18 m/s
u = 15 m/s
Car stops on applying brakes 20m
Displacement is covered by car ,S = 20m
finally car stops ∴ final velocity of car , v = 0
Now, use formula
V² = u² + 2aS , here a is Acceleration
⇒ 0 = (15)² + 2 × a × 20
⇒ -225 = 40a
⇒ a = -5.625 m/s² [ here negative sign shows that acceleration is opposite direction of motion of car ]
Hence, magnitude of acceleration = 5.625 m/s²
0.16 that is the answer!!!!
First you change 7/15 into a decimal which is—0.466666..repeating then just do 0.46 multiplied by 100 and get—46 so its 46%
