Do question 7 please
Write log ((w + 4)^3/squareroot x z^5) as the sum, difference and/or multiple of logs. b) Use your calculator to find log_15(345678) to 4 decimal places ___ c) Find the inverse function for f(x) = log_4(x-3) Solve the logarithmic equation. Provide all of the solutions rounded to one decimal place and check. log_2(x - 7) + log_2(x) = 3 Find all real solutions, x, to 3 decimal places: e^2x - e^x = 6 Suppose $6000 is in a saving account paying an annual interest rate of r% 10 suppose compounded continuously. If the amount in the account after 30 years is $48000, find the annual percent rate rounded off to the nearest 1/10%. (Use A = Pe^rt here) How much must be invested at 6% per year compounded monthly, so that after 30 years it would be worth $40, 000? (Use A = P(1 + r/n)^nt here)Explanation / Answer
7)
a) = 3 log (w+4) - (1/2) log x - 5 log z
b) log15(345678) = 4.7093
c) let inverse function is g(x) then
g(x) = 4^x + 3
