Question:

Charlie does the following problem: 3 3 • 3 2 = 3 6 = 3 • 3 • 3 • 3 • 3 • 3 = 729. Which of the following is a true statement?

Solution:

Charlies 729

What he did wrong was he multiplied the exponets in which he should have. its really 3^5.

Final

B. He is incorrect because he should have only 5 factors of 3.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
