-12 because surface is usually considered as "0" so 12 ft below the surface means -12.
Answer:
Both of them can be simplified.
Recall that 4 = 2^2.
2^7 / 4^2 = 2^7 / (2^2)^2 = 2^7 / 2^4 = 2^(7-4) = 2^3 = 8
Similarly, 2^7 / 2^4 = 2^(7-4) = 2^3 = 8
The answers to both exercises are 8.
Answer:
31
Step-by-step explanation:
first find f(-3)
f(-3) = (-3)^2 +5
= 9+5 = 14
The find g(f(-3) = g(14)
= 3*14-11
= 42-11
=31
Answer:
0
Step-by-step explanation:
any thing that is multiplied by 0 will be 0
<span>$16,000 / (100% - 20%) = $16,000 / .8 = $20,000
to verify, work the answer backwards.
$20,000 - $20,000 * 20% = $20,000 - $4,000 = $16,000
