Question

INVESTING Maria invests $1000 in a savings account that pays 4% interest compounded annually. The value of the account A at the end of five years can be determined from the equation log10 A = log10[1000(1 + 0.04)5]. Write this equation in exponential form

Answer 1

Answer:

$A=1000(1+0.04)^5$

Step-by-step explanation:

-The general expression of an exponential function is :

$A=P(1+r)^n$

where:

• $A$ is the amount after time t.
• $P$ is the initial amount
• $r$ is the rate of growth
• $t$ is the time.

We substitute our parameter values in the equation as:

$A=1000(1+0.04)^5$
