Henry begins a savings account with 500 dollars The savings account accumulates 2 point 5 percent annual interest based on the equation cap v sub h is equal to 500 times 1 point 0 2 5 to the t th power , where cap v sub h is the value of the account after t years. Andres begins a savings account three years later with the same initial amount of money at the same interest rate. Which equations represent the value of Andres’s account after t years?
The amount of radioactive element remaining, r , in a 100 -mg sample after d days is represented using the equation r is equal to 100 times 1 half raised to the d over 5 power What is the daily percent of decrease?
Consider the expression 1 point 1 times 1 point 3 raised to the x plus 4 power Which of the following is an equivalent expression?
A scientist has 50 grams of a radioactive element. The amount of radioactive element remaining after t days can be determined using the equation f of t is equal to 50 times 1 half raised to the t over 5 power After two days the scientist receives a second shipment of 50 grams of the same element. The equation used to represent the amount of shipment 2 remaining after t days is f of t is equal to 50 times 1 half raised to the the fraction with numerator t minus 2 and denominator 5 power Which of the following is an equivalent form of the expression for the amount remaining in shipment 2 ?
Nolan began a savings account three years ago. He invested 100 dollars at a 2 percent interest rate according to the equation cap v sub n is equal to 100 times 1 point 0 2 to the x th power , where cap v sub n is the value of his account after x years. Anias started an account today. She invested 100 dollars at a 2 percent interest rate according to the equation cap v sub A is equal to 100 times 1 point 0 2 raised to the x minus 3 power , where cap v sub A is the value of her account. Let’s say Anias started saving at the same time Nolan did, three years ago. Approximately how much money would she have had to invest to have the same amount of money she has now?
An antibiotic kills 60 percent of bacteria in a sample of 100 comma 000 each day. The equation p sub 1 is equal to 100 comma 000 times 0 point 4 to the d th power represents the population, p sub 1 , after d days. Four days after introducing the antibiotic to the first sample, a scientist introduces the same antibiotic to a second population, p sub 2 The number of bacteria after d days in the second population is represented by the equation p sub 2 is equal to 100 comma 000 times 0 point 4 raised to the d minus 4 power Which equation is equivalent to p sub 2 ?
Jenny invests 2 dollars comma 000 at an interest rate of 5 percent The amount of money, m sub A , in Jenny’s account after t years can be represented using the equation m sub A is equal to 2000 times 1 point 0 5 to the t th power If Jenny would have invested the same amount of money at the same interest rate four years ago, the equation representing the amount of money, m sub b , in her account would be represented using the equation m sub b is equal to 2000 times 1 point 0 5 raised to the t plus 4 power Which of the following is equivalent to m sub b ?
The value, cap v , of Kalani’s stock investments over a time period, x , can be determined using the equation cap v is equal to 750 times 0 point 8 0 raised to the negative x power What is the rate of increase or decrease associated with this account?
Which of the following is equivalent to 1 half raised to the negative 2 t power ?
Jillana takes a single dose of medication that remains in her body according to the equation r is equal to 200 times 0 point 7 5 to the d th power , where r represents the amount of medication remaining after d days. If Jillana had taken the medication two days earlier, the amount of medication remaining in her system relative to the amount that remains in her system after d days would be represented using the equation r sub 2 is equal to 200 times 0 point 7 5 raised to the d plus 2 power Which of the following is an equivalent equation?
