Answer:

Step-by-step explanation:
The depth function is:

After 3 minutes, a submarine had descended to −320 feet.
This means that
. So


After 8 minutes, the submarine had descended to −420 feet.
This means that
. So


From the first equation:

So





And

So

Answer: 10x - 25x - 35
Step-by-step explanation:
F 2x times 5x = 10x
O 2x times 5 = 10x
I -7 times 5x = -35x
L -7 times 5 = -35

Answer:
-2
Step-by-step explanation:
Let x be the unknown value
Log₆ ( 1/36) = x
( 1/36) = 36⁻¹ = (6²)⁻¹ = 6⁻²
Log₆ ( 1/36) = Log₆
6⁻² = -2 Log₆
6
Log₆
6 = 1
-2 Log₆
6 = -2(1) = -2
