For this case we have that by definition of multiplication of powers of the same base, the same base is placed and the exponents are added:
So, we can rewrite the given expression as:
So, if 
:
Equality is met!
Answer:
To simplify the problem imagine the half-life was 2.5 minutes. This means that there would be 10/2.5=4 periods of halving the mass, which means 1/2⁴=1/16 of 18g=1.125g.
So for the given half-life we calculate 10/2.552=3.9185 approx. So we now find 2 to this power=15.1211 approx and divide into 18=1.19g. This is close to the rough estimate we did earlier.
Answer: B; here's a brief explanation as to why:
g(x) is an equation that has a -1 being distributed to both x^2 and -2, making the equation really -x^2 + 2,
the - in x^2 would flip the line on the X axis, while the + 2 would raise the line up by two
Answer:
1431
Step-by-step explanation:
multiply height * length * width to get the volume of a shape
Answer:approximately a little more than 32 hours
Step-by-step explanation:
422/30 = 455/x
422x = 30*455
422x = 13,650
x=32.345971
