A person stands on a bridge suspended over a river and shoots an arrow straight up into the air. The arrow has an initial velocity of 79.5 m/s and it takes 8.15 seconds to reach a height of 346 meters above the water.
How high above the river is the bridge?

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

$97520

step-by-step explanation:

add 6% to the value she got from selling the house.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

the answer is 21%.
