13. Pick a point and see which formula works.
Ay = -4, A'y = 7. Only the formula of selection D makes that translation.
14. Use the compound interest formula A = P*(1 +r/n)^(nt).
..1500*1.015^80 = 4935.99, matching selection C
15. The lid has a perimeter of 90", so the area of the sides is
.. 90" * 24" = 2160 in^2
The area of the lid is
.. 30" * 15" = 450 in^2
The gray area is (2160 -450) in^2 = 1710 in^2 larger, corresponding to selection C.
16. The only formula that maps (7, -1) to (21, -3) is that of selection D.

1/10 is the answer if you divide 10,000 from 1,000
Answer:
Diameter: 4
Radius: 2
Equation: ( x-3 ) + ( y + 2) = 4
Assuming 2032 is itself a number in base 4, you have
Or, if you mean to ask about converting 2032 into base 4, you have
with remainder 0, which means the "ones" digit is 0.
with remainder 0, which means the "tens" digit is also 0.
with remainder 3, so the "hundreds" digit is 3.
with remainder 3, so the "thousands" digit is also 3.
with remainder 3, so the next digit is also 3.
with remainder 1, so the next (and final) digit is 1.
So,
.
