The question is incomplete, the complete question is;
A factory produces 1,250,000 toys each year. The number of toys is expected to increase by about 150% per year. Which model can be used to find the number of toys being produced, n (in millions), in t years?
A. n= 2.5(1.5)/t, t cannot = 0
B. n= 1.5t^2 + 1.25
C. n= 1.5t + 1.25
D. n= 1.25(2.5^t)
Answer:
D. n= 1.25(2.5^t)
Step-by-step explanation:
This is an exponential growth problem. In mathematics, for an exponential growth problem;
P = Po(1 + r)^t
Where;
P= amount at time t
Po =initial amount
r= rate
t= time
In the context of the question we have;
n= 1.25(1 + 150/100)^t
n= 1.25(2.5)^t

Answer:
The sum of heats gained is zero.
Step-by-step explanation:
Πr²h(2)-πr²h(1)=πr²(h(2)-h(1))=V2-V1
V2-V1=πr²(h(2)-h(1))
314-188.4=π*2²(h(2)-h(1))
(h(2)-h(1))=(314-188.4)/4π=10
difference is 10 cm
