Hey
Transposing log x to other side :
Using Logarithmic Property :
Raising to the power 2 :
Hence, [ x = 2 ] is the only real solution !
In the form of the exponential function:f ( x ) = a · b^x,the base of the function is b.In this case: a = 7,000 ( starting value ) and b = 1 - 0.1 = 0.9f ( x ) = 7,000 · ( 0.9 )^xwhere x represents the number of the years : x = 0, 1, 2, ...Answer: The base is 0.9.
Answer: B

Answer:
the elapsed time would be 19 hours and 5 minutes
The formula for the surface area of a sphere is
If your radius is 2, then filling in that formula looks like this:
or
. If you leave your answer in terms of pi, which is the exact answer, you're done. But if you multiply pi in, your surface area is SA = 50.264 square cm.
