In a survey in 2010, the population of two plant species were found to be growing exponentially. their growth is given by these equations: species a, p=2000e ^0.05t and species b, p=5000e^0.02t , where t = 0 in the year 2010.

4. after how many years will the population of species a be equal to the population of species b in the forest?

On new year's day, the average temperature of a city is 5.7 degrees celsius. but for new year's day 2012, the temperature was 9.8 degrees below the average. i) if a represents the average temperature on new year's day and 7 represents the temperature on new year's day 2012, what formula accurately relates the two values together? ii) what was the temperature on new year's day 2012? dt a 0.8 ii) - 4 1 degrees celsius da-t-98 ii) 59 degrees celsius 1) 7 = -9,8 11) 59 degrees celsius ii) l degrees celsius

In right ∆abc shown below, the midpoint of hypotenuse ac is located at d and segment bd is drawn.if ab = 12 and bc = 16, then explain why bd = 10. hint: consider what you know about the diagonals of a rectangle.

If you answer 2+2 you will get over 80 points
