0.00045−2.5⋅10 −5 = what is the answer i been up all day
Mama L [17]
If I’m getting this right the equation is: 0.00045 - 2.5 x 10 - 5? The dot in between 2.5 and 10 indicates a multiplication sign

So...

0.00045 - (2.5 x 10) - 5
0.00045 - 25 - 5
= -29.9999 -> -30

a scientist counts 25 bacteria present in a culture and finds that the number of bacteria triples each hour. the function y=25*3
navik [9.2K]
Y=25*3^x
1170=25*3^x
25*3^x=1170
3^x=1170/25
3^x=46.8
Log10(3^x)=LOg10(46.8)
x*log10(3)=log10(46.8)
x=(log10/46.8))/(log10(3))
x=1.60724585307/0.47712125472
x=3.50067375233
x=3.50
