  2. 5. A number is greater than 3 but less than 8. Also, the number is greater than 6 but less than 10. What is the number?
  3. 7. An object is heated to 838◦ and then allowed to cool in air that is 70◦ Suppose that it takes 2 hours to cool the object to 313◦. Then it takes minutes to cool the object to 646◦ Hint: Use Newton’s law of cooling.

  3. 4. Find the slope of the line tangent to f(x) at x=3. f(x)=x^2−6x+9
  4. 6. Consider an equilateral triangle of a side of unit length. A new equilateral triangle is formed by joining the mid-points of one, then a third equilateral triangle is formed by joining the mid-points of second. The process is continued. The perimeter of all triangles, thus formed is
