First, find the area of the pool
(8)(4)(5) = 160
160 / 15 = 10.67
round 10.67 to 11
11(10) = 110
it will cost 110 dollars

f(3) = 69
Step-by-step explanation:
Given f(x) =5x5 + 10x4 + 3x3 + 8x2 – 6x – 3; c = 3
f(x) = 25+40+9+16 - 6x - 3
f(x) = - 6x +90-3
f(x) = - 6f(3) = 69x + 87
Taken c = 3
f(c) = - 6c +90-3
f(c) = - 6c + 87
substitute c=3
f(3) = - 6 (3) +90-3
= -18 +87
= 69
Hence .,f(3) = 69
The only even numbers are 2,4,6 and the only even prime number is 2 so your answer is 1/6
Answer:
= 4374.
Step-by-step explanation:
it is important to understand the pattern hidden in such problem.Let’s give it a try 2, 6, 18, 54 and so on.It can be written as 2, 3*2, 9*2, 27*2 and so on.
This can be further written as2 (1, 3, 9, 27, and so on) as 2 is common in every term.Now if you see the chain 1,3,9, 27 and so….you will see a pattern hidden i.e. 3=1*3 ,9=1*3*3, 27=1*3*3*3 now 27 is the 4th term consist of three 3. So 8th term would consist of seven 3. 8th would be 8th term = 1*3*3*3*3*3*3*3 = 2187 Hence the 8th term for the series 2,6,18,54 would be= 2*2187 = 4374.
