Answer:
75 seconds to run 180 meters
Step-by-step explanation:
(180m) / (2.4m/s) = 75 seconds
75 seconds to run 180 meters, but if we take into consideration the initial 39 seconds, then the total time it took to run (75s + 39s) was 114 seconds.
The question didn't explicitly ask the total time it took, but the time it took to run 180 meters.
The first step to calculate the APR is to calculate the interest rate per $100
Here Interest rate = 11%
Term or time of repayment = 18 months
interest per $100 =
$100 × 11% × 
= $16.50
Now we should calculate the interest part for $3400 for 18 months
× 
= $31.12
So $ 31.17 is the interest part of the repayment amount
Now lets calculate the principal part which would be $ 3400 divided equally for 18 months

Now to find the final payment we add the interest and the principal part
$31.17+$188.89 = $220.06
Hence option D is the right answer

Answer:
Step-by-step explanation:
Use the Quadratic Formula.
-x² - 4x + 16 = 0
x = [4±√(4²-4(-1)(16)]/[2(-1)] = [4±√80]/(-2) = [4±4√5]/(-2) = -2±2√5
