Answer:
Congrats! I got mine like a year ago lol
As the variation is direct we have:
We must find the value of k.
For this, we use the following data:
y = 200 when x = 5
Substituting values we have:
Clearing k:
Then, the function is:
We evaluate the function for x = -3
Answer:
the value of y when x = -3 is:
c.
72
False, it is not a repeating decimal
9/4 = 2.25
Savings account100 shares x $9.75 = $975, then multiplied by 0.045 will result to $43.89.
Stock100 shares x $9.75 = $975, then multiplied by 0.08 will result to $78.00.
So, the difference between your stocks and savings account by end of the year is $34.11 ($78.00 deducted by $43.89).Your stock is gaining higher APR by $34.11 than what's calculated in your savings account.
