Let's say the numbers are "a" and "b"
thus
set the derivative to 0, and check the critical points, there's only one anyway
and do a first-derivative test, to see if it's a maximum
Answer:
C. 
Step-by-step explanation:
To find slope using coordinates, use the formula above.
Now, using the 
formula, plug in 
as 
(slope) and either coordinate as the 
and 
values. It looks like this:
To solve for 
, continue to use PEMDAS.
Now use and to solve for your equation:
The answer is C.
Answer:
i don't know its ans thank you
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 :)
