Answer:

It will take 47 hours

Step-by-step explanation:

We can have the exponential function as follows;

P = I( 1 + r)^n

if the initial value was x , the final will be 2x

The change rate is 1.5% , which is r, this is same as;

1.5/100 = 0.015

So what we want to calculate is the n attached

This will be;

2x = x ( 1 + 0.015)^n

2 = 1.015^n

ln 2 = n ln 1.015

n = ln 2/ln 1.015

n = 46.55

This is approximately 47 hours

Which expression is equivalent to 2^4 ⋅ 2^−7?
yaroslaw [1]
Remember
(x^m)(x^n)=x^{m+n}
and
x^{-m}=\frac{1}{x^m}

so
(2^4)(2^{-7})=
2^{4-7}=
2^{-3}=
\frac{1}{2^3}=
\frac{1}{8}
