I found my notes for this exact paper and I have that first problem written. hopefully this helps
Answer:
16x11/y (i hope)
Step-by-step explanation:
The value of 4 is Hundreds.
Your welcome
T = 40000 + 40000(1.03) + 40000(1.03)^2 + ... + 40000(1.03)^15
Multiply the above equation by 1.03 giving
1.03(T) = 40000(1.03) + 40000(1.03)^2 + 40000(1.03)^3 + ... + 40000(1.03)^15 + 40000(1.03)^16
Now subtract the first equation from the second to give
0.03T = 40000(1.03)^16 - 40000
0.03T = 40000(1.03^16 - 1)
0.03T = 24188.26
T = 24188.26 / 0.03 = $806275.25
Multiplying an odd number of negative factors equals a negative
-5* 2n -1
Calculate the product
the answer is -10n - 1
