Answer:
The sequence is arithmetic with a common difference of -10
Step-by-step explanation:
From the question, we want to determine if the sequence is arithmetic or geometric
From the question
f(1) = 5
f(2) = -5
f(3) = -15
Mathematically for the common difference;
f(3) - f(2) = f(2) - f(1)
Since;
-15-(-5) = -5-5
-10 = -10
Since the common difference here is same , then the sequence is arithmetic with a common difference of -10
Simplifying the expression we proceed as follows:
√8×20
=√8×√20
=√(2×4)×√(4×5)
=2√2×2√5
=4√10
Answer: 4√10
Answer: 2/5%
Step-by-step explanation: First, convert 0.4 into 4/10. Then, divide the numerator and the denominator by 2. You should get 2/5, which can’t be simplified any more. Voila!
