no this relation is not a function, because for each input (x), there is no output (y)
Answer: acute 90-
Step-by-step explanation:
Answer:
aₙ = 4(5)ⁿ⁻¹
Explanation:
To identify a geometric series: second term = √(first term * third term)
Here given:
check ============
20 = √(100*4)
20 = √400
20 = 20 Hence its a geometric term.
Find common difference (r):
20/4 = <u>5</u> or 100/20 = <u>5</u>
Geometric term formula:
aₙ = a₁(r)ⁿ⁻¹ [where a1 is the 1st term, r is common difference]
<u>insert values found</u>
aₙ = 4(5)ⁿ⁻¹ ......this is the nth term.
Answer: The answer is 5.472
Step-by-step explanation:
-0.84 ÷ 2.1 = -0.4
-0.4 + 5.872 = <em>5.472</em>
