Answer:
a₂ = - 28.5
Step-by-step explanation:
the nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = - 45 and given a₃ = - 12 , then
a₁ + 2d = - 12 , that is
- 45 + 2d = - 12 ( add 45 to both sides )
2d = 33 ( divide both sides by 2 )
d = 16.5
Then
a₂ = a₁ + d = - 45 + 16.5 = - 28.5
Answer:
1312842
Step-by-step explanation:
The year is 2019. 2035 - 2019 = 16 years
The equation for growth is:
initial_amount * (( 1 + percent_in_decimal_form) ^ years)
So now substitute numbers in the equation.
884363 * ((1 + 0.025) ^ 16) = 1312841.8 = 1312842
There's no way to begin until we know the value of ' i ' .
If ' i ' doesn't represent √-1 , then we can stop here
and discard the question as unanswerable.
If ' i ' is the famous √-1 , then here's how i⁵⁰ can be simplified:
Notice the following:
-- The 1st power of i is √-1 .
-- The 2nd power of i is (√-1)² = -1
-- The 3rd power of i is -√-1
-- The 4th power of i is (-√-1)·(√-1) = -(-1) = 1 .
-- Every 4 powers of ' i ' brings you back to ' 1 '.
So from the exponent of 50, you can knock out
the largest possible multiple of 4 , and evaluate
what's left.
50 = 48 + 2
i⁵⁰ = i² = -1 .
Answer:
2
Step-by-step explanation:
because its the middle (i think)
median=middle
Let's solve this with the quadratic formula, which is:
Let's plug in the values:
Remove exponents:
Simplify.
This leaves us with the final solutions being:
