Answer:
Step-by-step explanation:
<h3>Part 1</h3>
- P = $800
- r = 2% (since P > $500)
- I = $100
- t = ?
<u>Find t:</u>
- 100 = 800*0.02t
- 0.16t = 1
- t = 1/0.16
- t = 6.25 years
<h3>Part 2</h3>
- P = $100
- r = 1.5% (since P < $500)
- I = $50
- t = ?
<u>Find t:</u>
- 50 = 100*0.015t
- 0.03t = 1
- t = 1/0.03
- t = 33.33 years
<h3>Part 3</h3>
- P = $10000
- r = 3% (since P > $5000)
- I = $750
- t = ?
<u>Find t:</u>
- 750 = 10000*0.03t
- 300t = 750
- t = 750/300
- t = 2.5 years
Answer:
a. Amplitude: 19.65446
b. Vertical Shift: 58.00713
c. Period: 2
/0.22797 = 27.56146
d. 19.65446 * sin(0.22797x + 1.79552) + 58.00713
e. Model's Temperature at 10 A.M.: f(-7) = 61.91
This value is 9.91 degrees higher than the actual value.
Step-by-step explanation:
Used graphing calculator's stat calculations
x/ 7 - 1 = 8 -Subtract 1 from 7
x / 6 = 8 -Multiply both sides by 6
x = 48
Check:
48 / 7 - 1 = 8
48 / 6 = 8
8 = 8
Hope this helps!
