SEE FIRST PHOTO TO TAKE FORMULA AND ANSWER 1 and 2



1) The population of bacteria on a dirty toilet doubles every 20 minutes. Determine the time for the
population to triple if it starts at 1000 bacteria. Use = A. (2)6, where D is the time to double, tis
the time it takes to triple.


2) Radioactive copper is injected to scan the brain. It can often detect brain tumours because the tumours take up the copper more than the normal tissue. The half life of copper is 12.7 hours. A patient is injected with 100 units of copper-64. Determine what the formula would look like. (1 mark)
(No need to solve just fil in the formula)

3) Solve the exponential equation (variable is in the exponent position) using the same bases.
81^-x= 9^-x-2


4) Solve for x by using the same base form
2^4x (16x)^x+3=4^x-1


5) Solve for x. (1/4)^x=8^x-1

6) Convert 𝑦 = 4(5)^x to log form

7) Convert 𝑙𝑜𝑔464 = 𝑥 𝑡𝑜 𝑒𝑥𝑝𝑜𝑛𝑒𝑛𝑡 𝑓𝑜𝑟𝑚 (base4)

8) Convert 2𝑙𝑜𝑔28 = 𝑥 to exponential form (base2)

9) SEE IMAGE ATTACHED SECOND one
