Answer:
.66
Step-by-step explanation:
Answer:
7..the way you worded the options was confusing
Step-by-step explanation:
∫₀³⁰ (r/V C₀ e^(-rt/V)) dt
If u = -rt/V, then du = -r/V dt.
∫ -C₀ e^u du
-C₀ ∫ e^u du
-C₀ e^u + C
-C₀ e^(-rt/V) + C
Evaluate between t=0 and t=30.
-C₀ e^(-30r/V) − -C₀ e^(-0r/V)
-C₀ e^(-30r/V) + C₀
C₀ (-e^(-30r/V) + 1)
I got the same answer. Try changing the lowercase v to an uppercase V.
Answer:
x=30
Step-by-step explanation:
2x+2x+x+x=180
6x=180
x=30
Answer:20+10
Step-by-step explanation:It is 20 plus 10 because 6 times 5 is 30 and so is 20 plus 10.
