Answer:

Exponential model best fits this situation.

Step-by-step explanation:

Given : Karl has $400 in a savings account. The interest rate is 10%, compounded annually.

We have to determine which type of model best fits this situation.

Since, interest is calculated compounded

Using formula for compounded  interest , we have,

A=P(1+r)^n

Where P is principal amount

n is time period

r is interest rate

We are given P = $ 400

and r = 10 % = 0.10

Substitute, we have,

A=400(1+0.10)^n

A=400(1.10)^n

Now this is an equation of the form a^x which is exponential function.

So, exponential model best fits this situation.

What is the value of x
Colt1911 [192]

Answer:

The value of x are all real number on x-axis the number that falls under x

example of the value of x are in this equation

y=2+5x

2x+6y=60

to find x

let make the first one equation 1 and the second equation 2

now, put equation 1 in equation 2

2x+6(2+5x)=92

open the by multiplying every thing in the bracket by 6

2x+12+30x=92

combine the like terms

2x+30x=69212

32x=80

now divide via by 32

32x/32=80/32

x=5/2

PLEASE HELP {It costs 5,700 every one sixth of an hour to build a hotel how many cents does building a hotel cost per second?}
Keith_Richards [23]
One sixth of an hour is 10 minutes.
That means it costs 5,700 every 10 minutes.

Costs 5,700 = 10 minutes

Dive 10 on both sides.

Costs 570 = 1 minute

Lets convert the minute into seconds.

Costs 570 = 60 seconds

Divide both sides by 60.

Costs 9.5 cents = 1 second

Round it off since you can't pay 9.5 cents.

Costs 10 cents = 1 second

This means that every second they pay 10 cents for the hotel. :D
