Step-by-step explanation:
1. 250×4=1000
2.125×8=1000
3. 25×40=1000
4. 500×2=1000
5. 200×5=1000
6. 50×20=1000
Time = distance / speed
time = (7/8) / (3/8)
= 7/8 * 8/3
= 7/3 or 2 1/3 minutes or 2 minutes and 20 seconds
Answer:
Public debt in 2010 is $10230355000000
Step-by-step explanation:
The debt of the country in year 2009 = $10432000000000
In 2010 it is deficit by =$201645000000
Deficit means decreased ,therefore we add to the amount of debt in the year of 2009 to find it for the year 2010.
Public debt in year 2010 = $10432000000000-$201645000000

Therefore amount of debt in 2010 will be $10230355000000
Smaller x = -1.33 and larger x = -1
Answer:
<u>The series:</u>
This is an AP with the first term a₁ = 10 and common difference d = 6
a) <u>Recursive formula:</u>
b) <u>Explicit formula:</u>
- aₙ = a₁ + 6(n - 1) ⇒ aₙ = 10 + 6n - 6 ⇒ aₙ = 6n + 4
c) <u>n = 5 ⇒ a₅ = ?</u>
d) <u>S₁₇ = ?</u>
- Sₙ = n(a₁ + aₙ)/2 = n(2a₁ + (n - 1)d)/2
- S₁₇ = 17(2*10 + 16*6)/2 = 986
