Answer: 1, 7, 1, 7, 1.
Step-by-step explanation:
The given function : 
and f(1) = 1 for n ≥ 1
We put value of n=1,2,3,4 , we get
For n=1 , 
For n=2 , 
For n=3 , 
For n=4 , 
Hence, the first five terms of the given sequence are 1, 7, 1, 7, 1.
Answer:
0.76m²
Step-by-step explanation:
In the above question, we are given the following information.
Radius = 0.4m
Height = 0.45m
To solve this question, The umbrella is CONICAL in shape and it has no BASE, we would be finding the lateral surface area of a cone. Since we are given height and radius :
Lateral Surface Area of a cone =
πr√(h² + r²)
= π × 0.4√(0.45² + 0.4)
= 0.7566m²
≈ Approximately = 0.76m²
Therefore, the amount of fabric needed to manufacture this umbrella is 0.76m²
Answer:
x = 2
Step-by-step explanation:
Start by combining like terms.
Collecting x terms onto the left side results in 8x;
collecting constants onto the right side results in 16.
Therefore, 8x = 16, and x = 2
It is a function because each x value only has one y value
Answer: 180 miles
Step-by-step explanation: 1cm=40 miles. There is 4.5 so 4*40=160 and there is also half a centimeter, which is 20 miles. 160+20
Hope this helps and brainliest would be appreciated
