Answer:
3.5
Step-by-step explanation:
98/8=12.25
√12.25=3.5
Answer:
see below
Step-by-step explanation:
6(y(2)−4)
=(6)(y(2)+−4)
=(6)(y(2))+(6)(−4)
=12y−24
6(y2−4)
=(6)(y2+−4)
=(6)(y2)+(6)(−4)
=6y2−24
Answer:
Average Velocity= 70 miles per hour
Step-by-step explanation:
Distance= s
Time = t
s(t)=10t^2
Putting the values
s(2) = 10 (2)^2= 10&4
s= 40
s(5) = 10 (5)^2 = 10*25
S(5)= 250
The average velocity is defined as the rate of change of speed in unit time.
So
Speed= distance/time
Velocity = Speed in a definite direction
Average Velocity= Displacement/ Time
Average Velocity= Change in distance/ Change in time
s(5) - s(2)/ t(5)- t(2)
= 250-40/5-2= 210/3= 70 miles per hour
