Answer:
Step-by-step explanation:
1. 8a+a^2-10
2. v-6w
3. -2c^2+4c
4. z^3+8z^2+5z+7
I think is should be (5,0)
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
55.76-50.38=4.38 inches of rainfall
