Answer:
d) geometric; r = 4
Step-by-step explanation:
Differences of adjacent terms are not constant (they are 1.2, 4.8, 19.2, ...), so the sequence is NOT ARITHMETIC.
Ratios of adjacent terms are constant (they are 1.6/0.4 = 6.4/1.6 = 25.6/6.4 = 4), so the sequence is geometric with a common ratio of 4.
Answer:
4.5 ounces
Step-by-step explanation:
First dived 3 by 2 to figure out how much water she drinks in 1/3 of a hour.
Second, you take the answer 1.5 ounces per 13 of an hour and multiply it by 3.
Lastly, you get your answer 4.5 ounces of water in a hour.
1. 3 / 2 = 1.5
2. 1.5 x 3 = 4.5
Answer:
is this a real question?
Step-by-step explanation:
We write the polynomial in its factored form first.
We have then:
(x + 2) * (x + 1) * (x-4) * (x-5)
We now rewrite the polynomial:
(x ^ 2 + x + 2x + 1) * (x ^ 2-5x-4x + 20)
(x ^ 2 + 3x + 1) * (x ^ 2-9x + 20)
x ^ 4 - 9x ^ 3 + 20x ^ 2 + 3x ^ 3 - 27x ^ 2 + 60x + x ^ 2 - 9x + 20
We now add terms of the same degree:
x ^ 4 + (-9 + 3) x ^ 3 + (20-27 + 1) x ^ 2 + (60-9) x + (20)
x ^ 4 + (-6) x ^ 3 + (-6) x ^ 2 + (21) x + (20)
x ^ 4 - 6x ^ 3 - 6x ^ 2 + 21x + 20
Answer:
The polynomial sought is:
x ^ 4 - 6x ^ 3 - 6x ^ 2 + 21x + 20
