Answer:
The value of the sculpture in 8 years is $258.865
Step-by-step explanation:
The original value of sculpture = $950
we are given that the value decreases by 15% each year.
Formula : 
Where N(t)=Value after t years
Initial value
r = rate of decrease in decimals
t = time
We are supposed to find the value of the sculpture in 8 years.
Substitute the values in the formula :
So,
Hence the value of the sculpture in 8 years is $258.865
Answer:
Position of the particle is 20.
Step-by-step explanation:
Position function is integration of velocity function.
Velocity function is integration of acceleration function.
So, let's integrate the given a(t) to get v(t)
If we integrate v(t) then we get s(t)
It is given the values of s(0) =0 and s(1)=20
So, position of the particle is difference of 20, 0. That's 20-0 =20.
