Hello,
s=48t-16t²
a)
s=0==>16t(3-t)=0==>t=0 or t=3
b)
s>32==>48t-16t²>32===>16(t²-3t+2)<0
Δ=9-8=1
==>16(t-1)(t-2)<0
==>1<t<2 (negative between the roots)
<span>f(x) = 4x + 3
g(x) = -2x + 5
(f o g) (5) means the function of g when g is a function of 5
(the function of the function concept)
so we need to get g(5) firstly
</span>
<span>g(x) = -2x + 5
g(5)= -2(5) + 5 = -5
After that, f(g(5)) = f(-5) = 4(-5) + 3 = -20 + 3 = -17
I hope that helps

True. Force is equal to mass times acceleration. So if we have a mass of 5kg and an acceleration of 3. Then the force is 15 N
Answer:
3 meters/second
Step-by-step explanation:
acceleration = rate of change of speed (velocity)/change in time
= 16 - 4/4
= 12/4 = 3 m/s
