Answer:

$y = \frac{7}{4} x - 3 \\ y = x \\ y = \frac{7}{4} y - 3 \\ y - \frac{7}{4} y = - 3 \\ - \frac{3}{4} y = - 3 \\ 3y = 12 \\ y = \frac{12}{3} \\ y = 4 = x$

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.
