V(t) = 2t^2 - 3t - 3
for an acceleration a(t),
a(t) = d (v(t)) / d t
a(t) = 4t - 3
at t=2
a(2) = 8 - 3
a(2) = 5 feet/s^2
Answer:
I'm not exactly sure what you want me to do but try using Symbolab bc it looks really confusing when you write it on here
Step-by-step explanation:
F(x) = 8 - 10xg(x) = 5x + 4
(fg)(x) = (8 - 10x)(5x + 4)
(fg)(x) = 40x + 32 - 50x^2 - 40x
(fg)(x) = 32 - 50x^2
(fg)(-2) = 32 - 50(-2)^2
(fg)(-2) = 32 - 200
(fg)(-2) = -168
Answer:
The value of the computer is given by 900(0.7)^t.
Step-by-step explanation:
A computer sells for $900.
If the price of the computer loses 30% of its value per year, then it is compounded every year.
Now, the price of the computer t years after it is sold will be
900(1 - 30/100)^t = 900(0.7)^t ........... (1)
Therefore, the value of the computer is given by the above equation (1). (Answer)
