Answer:
- a. $2480
- b. $4040
- c. 4 years and 2 months
- d. 8 years and 4 months
Step-by-step explanation:
a. Account after 4 years:
- 2000 + 4*2000*0.06 = $2480
b. Account after 17 years:
- 2000 + 17*2000*0.06 = $4040
c. Time when account = $2500:
- 2000 + x*2000*0.06 = 2500
- 120x = 500
- x = 500/120
- x = 4 20/120 = 4 2/12 years = 4 years and 2 months
d. Time when account = $3000
- 2000 + x*2000*0.06 = 3000
- 120x = 1000
- x = 1000/120
- x = 8 40/120 = 8 4/12 years = 8 years and 4 months
Initial mass: 34g
Daily reduction: 2.49g
The tumor mass, as function of days, is:
m(t)=34-2.49t, where t is time in days.
In the first day, t=0, mass is m(0)=34g. Next day, t=1, mass is m(1)=34-2.49.
After 5 days: m(5)=34-2.49×5=21.55g.
Answers: m(t)=34-2.49t
After 5 days: m(5)=21.55g
The answer is B

Answer: 1.4
Step-by-step explanation:
Answer:1 and 1/4
Step-by-step explanation:
Okay, let's see the given: 20/16
So, we can take out 16 from the top to make it 1 4/16
Now, we can simplify that by dividing the top and bottom by 2: 1 2/8
We can simplify that again to get 1 1/4
So the answer is 1 and 1/4
