- For the following exercises, use a graphing calculator to find approximate solutions to each equation. 2ln(5x+1)=12ln(5x)+1arrow_forwardFor the following exercises, solve the equation for x , if there is a solution. Than graph both sides of the equation, and observe the point of intersection (if it exists) to verify the solution. ln(2x+9)=ln(5x)arrow_forwardUsing Figure 7, solve f(x)=1 .arrow_forward
- The rate of change of an autocatalytic chemical reaction is kQxkx2 where Q is the amount of the original substance, x is the amount of substance formed, and k is a constant of proportionality. Factor the expression.arrow_forwardFor the following exercises, write the equation for the standard function represented by each of the graphs below.arrow_forwardRefer to the previous exercise. Suppose the lightmeter on a camera indicates an EI of 2 , and thedesired exposure time is 16 seconds. What should thef-stop setting be?arrow_forward
- The number of people in a school that have caught a cold can be modeled by C(d) = 3(4d) where C(d) is the number of people who have caught a cold after d days. (a) Use the model to estimate the number of people who have caught this cold after 5 days. (Include units in your answer. More information.) After 5 days have passed, X Units are required for this answer. have caught the cold. (b) Use the model to estimate how long it takes for 192 people to catch this cold. (Include units in your answer. More information.) It takes for 192 people to catch the cold.arrow_forwardWeekly sales of graphing calculators can be modeled by the equation s(t) = 10 – te-t/20 - where s is the number of graphing calculators sold per week after t weeks. How many graphing calculators will be sold in the first 80 weeks? calculators (include two decimal places)arrow_forwardA ferris wheel is 40 meters in diameter and boarded from a platform that is 1 meters above the ground. The six o'clock position on the ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 2 minutes. The function h = f(t) gives your height in meters above the ground t minutes after the wheel begins to turn. What is the equation for h = f(t)?arrow_forward
- Find d/dx of each. Simplify a little if possible. Full credit for maximum efficiency.arrow_forwardWhen fertilizer is introduced to a lake, it may or may not affect the kilograms of algae that are in the lake. In each of the cases below, write a formula for, A(t), the kilograms of algae in the lake t days after the fertilizer is introduced, Assume there are 90 kilograms of algae in the lake when t = 0. (a) the kilograms of algae remain constant each day. A(t)- (b) the kilograms of algae decrease at a continuous rate of 4%i each day A(t)- (C) the kilodrams of algae increase by a factor of 1.14 each day Alt)-arrow_forwardThe amount of a pollutant (measured as parts per million) in a local lake can be modeled by the function of A (t) = 14(2.71)-016i where t is the number of years since a government program was began to help clean up the lake. About how long will it take for the amount of pollutant to reach 7 parts per million?arrow_forward
