45 minutes = 3/4 hours
so his speed = 6 / 3/4 kph
= 8 km / h Answer
Answer:84
Step-by-step explanation:
Okay. Are you taking calc? Dv/dt =d/dt(L(t)^3)=d/dt[(sqrt(14)+2t)^3]= 6(Sqrt(14)+2t)^2)=44. We defined t=0 to be time at which length is sqrt(14). Does that work?
Answer:
m=6
Step-by-step explanation:
For this figure to be a parallelogram, the sides must be the same length
4m+2 = 3m+8
Subtract 3m from each side
4m+2-3m = 3m+8-3m
m+2 =8
Subtract 2 from each side
m+2-2 =8-2
m=6
2pirad=360 deg
so
xrad/2pi=ydeg/360
times both sides by 360 to solve for ydeg
180xrad/pi=ydeg
so
7/9pi rad
180(7/9pi)/pi=ydeg
140=ydeg
140 deg
