Answer:
A. -3.84 meters
Step-by-step explanation:
Given:
A penguin can dive 2% of the total depth every 1 second.
Total depth = 48 meters.
Now we have to find 2% of 48.
= 
= 
= 0.96 meter
So, the penguin dives -0.96 meters per seconds down the water.
The negative sign represents below the surface of the water.
The total depth of the penguin after 4 seconds = 4 times -0.96
= -3.84 meters
Therefore, the answer is A. -3.84 meters
Answer:
33 meters
51 meters
Step-by-step explanation:
84-18= 66
66/2= 33
33+18= 51
Check your answer:
51+33=84
3 x 3 1/2. Well you know 1/2 times two is one and three times two is six and six plus one is seven and seven plus 3 1/2 is 10 1/2
X=9

The answer is letter c. x2-8x+24-[72/(x+3)]. If you do not know how to solve this using the long division method, you can always evaluate the options through the process of elimination first. Since the degree of the other factor is already 1 (x to the power of 1), you know that option d. is not the correct answer because you know that the other factor must be raised to the power of 2. That leaves us with a, b and c. Working backwards and multiplying the given factor (x+3) with the factor in b, gives us x3-5x2+72. So from there, you know that you have to eliminate 72, which can be removed when it is subtracted by itself. Letter c does just that. Try multiplying (x+3) and option c for yourself :).
