(x² + 16)(x² - 16)
= (x²)² - 16²
= x⁴ - 256
Answer: 2.73 x 10 the the power of 2
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
We have been given a geometric sequence 18,12,8,16/3,.. We are asked to find the common ratio of given geometric sequence.
We can find common ratio of geometric sequence by dividing any number by its previous number in the sequence.
Let us use two consecutive numbers of our sequence in above formula.
will be 12 and 
will be 18 for our given sequence.
Dividing our numerator and denominator by 6 we will get,
Let us use numbers 8 and 16/3 in above formula.
Therefore, we get as common ratio of our given geometric sequence.
This is because astronauts can't sprinkle salt and pepper on their food in space. The salt and pepper would simply float away. There is a danger they could clog air vents, contaminate equipment or get stuck in an astronaut's eyes, mouth or nose. Astronauts eat three meals a day: breakfast, lunch and dinner.
Since p varies directly with l,
p = kl (1)
Also, since w varies directly with l,
w = ml
or, l = w/m
Substitute in (1), we get,
p = k (w/m)
= (k/m) w
So, the price varies directly with weight.
