Answer:

The initial amount in the account is $500.

Step-by-step explanation:

The amount of money in a savings account after t years is represented by the function f(t)=500(1.015)t.

General form of exponential growth function is

y=a(1+r)^t

y is the accumulated amount

a is the initial amount in the account

r is the rate of interest

t is the time period

y=500(1+0.15)^t

Here 500 is the initial amount in the account.

What is the minimum y-value after which the exponential function will always be greater than the linear function? y = 1 y = 2 y
Alenkinab [10]

From the graph we can see that in the interval [0,1] the value of y is less than 1.

In the interval [1,2] the value of y value is 2 to 4.

In the interval [2,infinity) the graph is going up, and the value of y is greater than or equal to 4.

Therefore, the graph going up after y=4 above the line.

Therefore, the minimum y-value is 4 after which the exponential function will always be greater than the linear function.

The circumference of the earth is 2.4x109 miles. if you traveled at an average of 8.5x10 miles per hour, how long would it take
pshichka [43]

Answer:

282 hr   <======= see below

Step-by-step explanation:

Distance / rate = time

2.4 x 10^9 mi / 85 m/hr   = 28235294 hr

 You must have left the power of 10 off of your speed

     probably should be   8.5 x 10^6  perhaps?   then answer is 282

<h3>If speed was 8.5 x 10^5   then answer becomes ~ 2820   </h3>
