Answer:
aₙ = 30 - 5n
Step-by-step explanation:
25,20,15,10, ...
<u>We see from the given series that it is AP with:</u>
- First term = 25
- Common difference = -5 and it is decreasing series
<u>Then formula is:</u>
- aₙ= a₁ + (n-1)d
- aₙ= 25 + (n-1)(-5)
- aₙ= 25 - 5n + 5
- aₙ = 30 - 5n
Answer:
Step-by-step explanation:
This is because you use Pythagorean theorem. a^2 + b^2 = c^2.
Answer:
Step-by-step explanation:
solve the quadratic equation
x² + 164 = 16x
x² - 16x + 164 = 0
quadratic formula
x = (16 ±√((-16)² - 4(1)(164))) / (2(1))
x = (16 ± √-400) / 2
x = (16 ± 20√-1) / 2
x = 8 ± 10√-1
as √-1 = i, the zeros are
x = 8 + 10i
x = 8 - 10i
