Answer:
676 assuming the population is 3800 in 2019. If it's a different year then change t.
Step-by-step explanation:

Answer:
Yes is linear because there is a constant rate of change this is also a function
Slope intercept for is y = -2x+4
Is there anything more to this question? Like are PT and TQ equal?
Answer:
(x-y)(x-y)(x-y)= x²-yx+x²-yx-yx+y²-yx+y²
2x²-4yx+2y²
(y-x)(y-x)= y²-yx-yx+x²
y²-2yx+x²
-(y²-2yx+x²) = -y²+2yx-x²
2x²-4yx+2y²-y²+2yx-x²= x²-2yx+y²
or
(x−y−1)(x−y)² ≡ x³−x²+3xy²+2xy−y³−y²−3yx³
