Kyle Nolan: Math Quiz

  1.  \( x^3-3x^2-10x=0 \)
  2. \( (1+r)^n \)
  3. \( (5.7\times10^{-8})\times(1.6\times10^{12})=9.12\times10^4 \)
  4. \( \pi L(1-\alpha)R^2=4\pi\sigma T^4R^2 \)
  5. \[ 12 \text{km} \times \frac{0.6 \text{Mile}}{1 \text{Km}} \approx 7.2 \text{Mile} \]
  6. \( {4,173,445,346.50} \approx {4,200,000,000} =4.2\times10^9 \)
  7. \[ 50\text{m} \times \frac{3.4\times10^6 \text{kg}} {1 \text{sec}} \times \frac {10 \text{J}}{1 \text{kg} \cdot 1 \text{m}} =1.7 \text{GW} \]
  8. \( \${5,000} \times (1+0.012)^{30} \approx \${7,150} \)
