1. Exponential growth & decay word problems (video)

You can do an exponential equation without a table and going straight to the equation, Y=C (1+/- r)^T with C being the starting value, the + being for a growth problem, the - being for a decay problem, the r being the percent increase or decrease, and the T being the time. Sal just uses a table to help him explain why the equation makes sense.

Exponential Word Problems: Growth & Decay Growth Formula: y = a (1 + r) t Decay Formula: y = a (1 - r) t ... Round your answers to the nearest whole number. 1. A town with a population of 5,000 grows 3% per year. Find the population at the end of 10 years. 2. Amy makes an initial investment of $5000. The investment loses 13.5% each year. 3. Exponential-Growth Word Problems Exponential word problems almost always work off the growth / decay formula, A = Pert, where " A " is the ending amount of whatever you're dealing with (for example, money sitting in an investment, bacteria growing in a petri dish, or radioactive decay of an element highlighting your X-ray), " P " is the beginning amount of that same "whatever", … 4. Exponential Growth Exponential growth y=a { { (1+r)}^x} y = a(1 + r)x We recall that the original exponential function has the form y = a { {b}^x} y = abx. In the original growth formula, we have replaced b with 1+ r 1 + r. So, in this formula we have: a= a = initial value. This is the starting amount before growth. r= r = growth rate. 5. Exponential model word problem: bacteria growth -- [ (√x)^2]^k can be simplified by multiply the exponents. This creates: (√x)^2k -- So, your problem becomes: log√x (√x)^2k -- The logarithm is asking you what exponent would you apply to √x to create (√x)^2k. The answer is 2k. Thus: log√x (x^2) = log√x (√x)^2k = 2k Hope this helps. Comment ( 2 votes) Upvote Downvote Flag more sanangelo9250 6.

Shota invests \$1000 $1000 in a certificate of deposit that earns interest. The investment's value is multiplied by 1.02 1.02 each year. 8. Exponential Growth and Decay Word Problems Solution : Since the initial amount of substance is not given and the problem is based on percentage, we have to assume that the initial amount of substance is 100. We have to use the formula given below to find the percent of substance after 6 hours. A = P (1 + r)n Substitute P = 100 r = -3.5% or -0.035 t = 6 9. Exponential Growth Exponential growth y=a { { (1+r)}^x} y = a(1 + r)x We recall that the original exponential function has the form y = a { {b}^x} y = abx. In the original growth formula, we have replaced b with 1+ r 1 + r. So, in this formula we have: a= a = initial value. This is the starting amount before growth. r= r = growth rate. 10.

19. 6.8: Exponential Growth and Decay

If a quantity grows exponentially, the time it takes for the quantity to double remains constant. In other words, it takes the same amount of time for a population of bacteria to grow from 100 to 200 bacteria as it does to grow from 10, 000 to 20, 000 bacteria. This time is called the doubling time.

If you do 400 * 5%, the result you get is equal to just the interest earned for the 1st year. The problem is asking you to find the balance in the account after 3 years. -- At the end of year 1, the account balance = the original amount (400) + interest (400 * 0.05). This can be simplified into 400 * 1.05. -- At the end of year 2, the account ...
