the function f(t)= 3,500(1.003)^t gives the value of a saving account t months after it was opened.How long will it take for the
Pavel [41]

Answer:

After 19 months,value in the account will reach $3700

Step-by-step explanation:

The value of a savings account f(t) in terms of t ( number of months since account opening) is given as \[3,500(1.003)^{t}\]

We need to determine the value of t when f(t)>=3700

Expressing it in equation form,

\[3,500(1.003)^{t} >= 3700\]

\[=>(1.003)^{t} >= \frac{3700}{3500}\]

\[=>(1.003)^{t} >= 1.057\]

Taking log of both sides,

\[=>t * log(1.003) >= log(1.057)\]

\[=>t >= \frac{log(1.057)}{log(1.003)}\]

\[=>t >= 18.51\]

So t = 19.

Does anyone know the answer to this? I can't understand why it isn't -7.​
faltersainse [42]

The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.

<h3>How to calculate the value?</h3>

From the information given, it should be noted that we simply want to calculate the value of x.

This will be:

18x + 9∆x - 7

It was stated that ∆x = 0

Therefore, we'll put this into the equation.

This will be:

18x + 9∆x - 7

= 18x + 9(0) - 7

= 18x -7
