Answer:
<em>Option A; the tournament did begin with 128 teams</em>
Step-by-step explanation:
We can see that this equation is represented by compound interest, in other words an exponential function, either being exponential growth or exponential decay;
f ( x ) = a + ( b )^x, where a ⇒ start value, b ⇒ constant, x ⇒ ( almost always considered ) time, but in this case rounds
Option A; The equation is given to be t ( x ) = 128 * ( 1/2 )^x. Given by the above, 128 should represent the start value, hinting that the tournament <em>did indeed begin with 128 teams</em>
Option B; As the rounds increase the number of teams approach 128. Now mind you 128 is the start value, not the end value, which would mean that <em>this statement is false</em>
Option C; The tournament began with 1/2 teams. Theoretically that would not be possible, but besides that the tournament began with 128 teams, only differed by 1/2 times as much every round. <em>This statement is thus false</em>
Option D; This situation actually represents exponential decay. If each round the number of teams differed by 1/2 times as much, the number of teams remaining is less than before, and thus this models exponential decay, not growth<em> ( statement is false )</em>
<em>Answer : Option A; the tournament did begin with 128 teams</em>
Since there are 120 payments in total
Then the total
interest paid is $ 9,118.32
The monthly interest = $ 9,118.32 / 120
The monthly interest = $ 75.99 per month
% total interest = ( $ 9,118.32/ 29,118.32) x 100
% total interest = 31.31 %
Answer:
Step-by-step explanation:
Answer:
A car traveling at a constant speed of 40 miles per hour
Step-by-step explanation:
The graph stays stagnant at 40 mph as the time continues. The other answers allow for the speed of the car to be a variable not constant.
