Answer:
r=21
Step-by-step explanation:
r-15=6
r=6+15
r=21
A.) P(t) = P0exp(kt)
P(20/60) = 40 exp(20k/60)
80 = 40 exp(k/3)
exp(k/3) = 80/40 = 2
k/3 = ln(2)
k = 3ln(2)
b.) P(8) = 40(2)^24 = 40(16777216) = 671088640 cells
d.) Rate of change = exp(8k) = exp(8(3ln(2)) = exp(24ln(2)) = exp(16.6355) = 16777216 cells / hour
e.) P(t) = 40(2)^3t; t in hours
1,000,000 = 40(8)^t
25,000 = 8^t
ln(25,000) = t ln(8)
t = ln(25,000)/ln(8) = 4.87 hours
Answer:
A parallelograms are rectangles
Hi there!
Here is the step by step explanation to solving this problem :
20% of $1,049
20% is the same thing as 0.2 & the word "of" is the same thing as a multiplication sign :
0.2 × 1,049 = $209.80
1,049 - 209.80 = $839.20 = price after discount
4.25% is the same thing as 0.0425 :
0.0425 × 839.20 ≅ $35.67
839.20 + 35.67 = $874.87
The total cost is : $874.87
There you go! I really hope this helped, if there's anything just let me know! :)
