Answer:
slope of AB=2
AB(distance)=4√5
Step-by-step explanation:
slope of AB=6-(-2)/-4-(-8)
=2
AB=√(-8-(-4))^(2+(-2-6)^(2
=4√5 or 8.94427
next time pls type clearly ur question, because actually I don't know what kind of answer that u want to know. sorry
Answer:
P=l+w
Step-by-step explanation:
Solve for P by simplifying both sides of the equation, then isolating the variable.
Answer:
B.
Step-by-step explanation:
Because if you subtract 19x and 18 from each side it wont be 0=0, in other equatins there is infinity solutions
A=(v-u)/t
We know a=2.5, v=40, u=10, so:
2.5=(40-10)/t
2.5t=40-10
2.5t=30
Divide both sides by 2.5
t=12 It takes 12 seconds for the car to reach 40m/s
To find out how far it went, you do:
d=v+1/2 at^2
d=10+1/2(2.5)(12)^2
d=10+1/2(2.5)(144)
d=10+(1.25)(72)
d=10+90
d=100m
Hope this helps :)
