Write in logarithmic form 3-3 =

Find the future value when $48,556 invested for 11 years at 5% compounded semiannually using the formulaA= P(1 + )nt

BONUS:  Solve the problem. Coyotes are one of the few species of North American animals with an expanding range. The future population of coyotes in a region of Mississippi can be modeled by the equation , where t is time in years. Use the equation to determine when the population will reach 140. (Round to the nearest tenth of a year.)t = [a]

Which of the following function(s) is/are one-to-one.  Select any that are 1-1 (multiple answers are possible as well as no answers are possible).  

Which of the following function(s) is/are one-to-one. Select any that are 1-1 (multiple answers are possible as well as no answers are possible).

Fill-in-the-Blank: A function f is a – – function if for a and b in the domain of f, if then 1.

Solve the exponential equation using the graphing calculator and approximate the result, correct to three decimal places. 7x + 6 = 9x

BONUS: Solve the equation algebraically showing all work on your paper and upload at the end on the last problem of the test. Give an exact answer. Also give approximate solutions to 4 decimal places, if necessary. Fill-in-the-blank below. 33x – 3 = 25x – 4                  x= [a] Credit given only if you show work on your own paper and upload on the last problem of the test

BONUS: Fill-in-multiple-blanks. Find variables A through H that follow from the steps shown below solving the logarithm equation. No partial credit – must get all to get credit for the problem. A ln (2x + 9) + B = 29 A ln (2x + 9) = 24 ln (2x + 9) = C D6 = 2x + 9 ​       EF + G = 2x = x A = [a]       B = [b]     C = [c]       D = [d]          E = [e]        F = [f]          G = [g]       H = [h]          

Select and Fill-in-the-Blanks: The function defined by f (x) = (x + 3)2 ; x ≥ 0 [verb1] a one-to-one function, while the similar function g(x) = x2 – 9; x ≥ -3 [verb2] a one-to-one function. 1.
