At the beginning of an environmental study, a forest covered an area of 1500km2. Since then, this area has decreased by 3.3% each year. Let t be the number of years since the start of the study.Let y be the area that the forest covers in km2 .Write an exponential function showing the relationship between y and t .

1. Use the quadratic equation y = x2 + 3x + 9.Where does the vertex of the parabola lie?   below the x-axis  above the x-axis  on the x-axis  on the y-axisQuestion 2.2. Calculate the discriminant to determine the number of real roots.y = x2 – 6x + 9.How many real roots does the equation have?   one real root  two real roots  no real roots  no solution to the equation10. Factor the expression.4x3y – 6x2y2 + 4x2y  2x2y(3x – 3y)  2x2y(2x – 3y + 2)  3x2y(2x – 3y + 1)  The expression cannot be factored because it is prime.Question 11.11. Factor the expression.c2 + 4c – 4  (c + 2)2  (c + 1)(c + 4)  (c2 + 4)2  The expression cannot be factored because it is prime.Question 12.12. If p varies directly with q, and p = 10 when q = 2, what is the value of p when q = 20?   p = 1  p = 28  p = 40  p = 100
