In scientific notation, if the exponent of 10 is positive, the number is very very large. In the metric system, very large numbers are expressed in megameters (Mm) or gigameters (Gm). Gigameters is equal to 10⁹ meters. So, in SI prefix, that would be equal to 150 Gm. In kilometers, that would be equal to:
1.5×10¹¹ m * (1 km/1000 m) = 1.5×10⁸ km
The "down" beat of a musical meter is always the strongest. This is because the human ear tends to associate this rhythm with the "heart" of the song, although some musical styles put the emphasis on the "off beat".
Answer:
a. slope=rise/run
rise=2
run=10
slope=2/10
slope=1/5
used point (0,0) and (10,2)
slope(m)=1/5
b. area= 0.5bh
0.5×50s×10m/s
a=25s×10m/s
a=250m
c.the area represents the total distance traveled after 50s by the toy
the slope represents the acceleration of the toy
the unit of slope is m/s²
slope=rise/run
slope(m)=(2m/s)÷10s
m=(2/10)m/s/s
m=(1/5)m/s²
.=0.2m/s²
