Speed=s'
acceleration=s''
take derititive to find speed
a.
I willl assume you know the power rule so
s'=6t²-18t+12
solve when s'=36
36=6t²-18t+12
6=t²-3t+2
0=t²-3t-4
0=(t-4)(t+1)
set to zero
t-4=0
t=4
t+1=0
t=-1, false no negative times allowed
at t=4 or 4 seconds
b. at t=4
take deritive again
s''=12t-18
at t=4
s''=12(4)-18
s''=48-18
s''=30
acceleartion is 30mpsps
a. at t=4
b. 30 meters per second per second
In y = mx + b form, the slope will be in the m position (the number right before the x) and the y intercept will be in the b position.
y = mx + b
y = 6x + 4....slope(m) = 6 and y int (b) = 4 or (0,4)
the rest can be done the same way.
On ur last one....y = -2...it is the same as y = -2x + 0
Answer: f(g(x))=
g(f(x))=
Step-by-step explanation:
f(g(x))=
f()=
=
f(g(x))=g(f(x))=
3x^5 - 8x^3 - 2x^2 + 5
ur terms are : 3x^5 and -8x^3 and -2x^2 and 5
so u have a polynomial with 4 terms
(X-4, y-9) since it moves left its negative and the y went down makes that negative too
