A culture starts with 230 bacteria. After 30 minutes the number of bacteria is 1150. 5.1 find a formula for the number of bacteria after t hours. 5.2 use the formula to find the number of bacteria after 1 hour. 5.3 after how many minutes will the number of bacteria be 125 times the original number? Leave the answer in terms of ln but in simplified form.

Suppose the functions f,g and h are defined by f(x)=3^x+3^-x+3 and g(x)=log5(x+2)+log5(3)-log4(2x-3) and h(x)=e^x+15e^-x respectively 4.1 write down the sets Df,DG and Dh that represent the domains of f g and h respectively. 4.2 solve the equation f(x)=12 for x. 4.3 solve the inequality g(x)= 0 for x. 4.4solve h(x)=8 for x. Leave the answer in terms of ln, where necessary
