Step-by-step explanation:
9/9 = 1 and 8/9 is only 1/9 less than 9/9 which is 1.
Answer: B) 1 8/9 is closer to 1
<u>Answer-</u>
<em>The exponential function that satisfies the given conditions is
</em>
<u>Solution-</u>
This can be represented as exponential decreasing function,

Where,
-
a = starting amount = 67
- r = rate = 0.47% = 0.0047
- t = week
Putting the values,


Therefore, the exponential function that satisfies the given conditions is

I believe it is {sqr(1/8)/2} or 0.5*sqr(1/8)
This question can be solved using 2 equations since there
are 2 unknowns. First, let x = price of the tennis ball and y = price of the
baseball. The resulting equations are: (1) 5x +3y = 23.75 and (2) 2x + 7y =
31.25. Solving the 2 equations simultaneously, you get, x = 2.5 and y = 3.75.
The price of the baseball is then $3.75.
