Math Quiz: Hannah Winn

1. \(x^3-3x^2-10x=0 \)

2. \((1+r)^n\)

3. \((5.7 \times 10^{-8}) \times (1.6 \times 10^{12})=9.12 \times 10^4\)

4: \(\pi L(1-\alpha)R^2=4 \pi  \sigma  T^4 R^2\)

5:\(12km \times \frac{0.6mile}{1km}\approx 7.2 mile\)

\[12 km \times \frac{0.6mile}{1km}\approx 7.2 mile\]

6: \(4, 173, 445, 346.50 \approx 4,200,000,000 = 4.2 \times 10^9\)

7. \[50 m \times \frac {3.4 \times 10^6 kg}{1 sec} \times \frac {10j}{1kg \cdot 1m} = 1.7 GW\]

8. \(\$ 5,000 \times (1+0.012)^{30} \approx \$ 7,150\)
