Given an exponential function for compounding interest, A(x) = P(.95)x, what is the rate of change?

statuscvo [17]

Answer:

Option 3

The rate of change is -5%

Step-by-step explanation:

Given : An exponential function for compounding interest, $A(x) = P(.95)^x$

To find : What is the rate of change?

Solution :

The general form of an exponential function is:

$f(x) = a(1+r)^x$

Where, a is the initial amount,

(1+r) is the rate of change,

r is the growth or decay factor

We have given, $A(x) = P(.95)^x$

Rate of change is

$1+r=0.95$

$r=0.95-1$

$r=-0.05$

Convert to percent,

$r=-0.05\times 100=-5\%$

Therefore, Option 3 is correct.

a family has two cars. the first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of

nikklg [1K]

Car A consumes 25 gallon and car B consumes 15 gallon.

Step-by-step explanation:

Given,

The fuel efficiency of car A = 20 miles per gallon.

The fuel efficiency of car B = 15 miles per gallon.

In a week, two cars went 725 miles and consumed 40 gallons.

To find the consumption of each car in that week.

Let,

Car A consumed x gallon

Car B consumed y gallon.

According to the problem,

x+y = 40 ----- (1)

20x+15y = 725

or, 4x+3y = 145 -------- (2)

From (1) we get, x = 40-y

Putting the value of x in (2) we get,

4(40-y)+3y = 145

or, 160-4y+3y = 145

or, -y = 145-160

or, y = 15

From (1) we get, x = 40-15 = 25

Hence,

Car A consumes 25 gallon and car B consumes 15 gallon.
