URGENT: DUE TONIGHT OR I GET DETENTION!!!!
suter [353]

Answer:

63 weeks

Step-by-step explanation:

252 - 3x = 378 - 5x

       + 5x          +5x

Add 5x to both sides

252 + 2x = 378

-252         - 252

Subtract 252 from both sides

2x = 126

Divide 2 from both sides

x = 63

Check you work by plugging 63 where the x is

252 - 3(63)

252 - 189 = 63

378 - 5(63)

378- 315 = 63

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.
