Firstly, the rate of increase of Canton = 80/7720 = 0.010
The rate of increase of HP = 120/3200 = 0.0375
Apply the formula of compound interest==> A =A'(1+i)^n
The population will be equal when the following equality is satisfied
7720(1+0.01)^n = 3200(1+0.0375)^n
or
7720x1.01^n = 3200x1.0375^n
Divide both sides by 3200 ===>(193/80)x1.01^n=1.0375^n
2508(1+0.04)^24 = 6,428. trust me, found it to 6,019.20.
b.
Answer:
D
Step-by-step explanation:
Because 20000 is the power of ten and i wrote it down on paper
Answer:
y=4x
Step-by-step explanation:
The equation of a line is y=mx+b, where m is the slope and b is the y intercept.
The slope formula is Δy/Δx, so using the coordinates (1, 4) and (2, 8), the slope is which equals 4.
The y intercept is 0.
Therefore, the equation is y=4x.
