Hi, can someone explain how to do 7h? It's the question about the pump.
Thanks in advance

Answer 1

which part?

Answer 2

oh i see h
did you get the period of the function?

Answer 3

@satellite73 yeah I got the period, it's 8 I believe

Answer 4

ok let me check

Answer 5

yeah, look like 8 from your eyeballs
so every 8 units the function repeats

Answer 6

at 1 it is the same as 9, 17, 25, 33, 41, etc etc

Answer 7

now you want it at 62 right?

Answer 8

Right

Answer 9

what is the remainder when you divide 62 by 8?

Answer 10

It's 7.75

Answer 11

oh i mean the integer remainder
as is 8 goes in to 62 whatever times with a remainder of blank

Answer 12

It goes into 62 7 times with a remainder of .75?

Answer 13

8 goes in to 62 7 times right? what is the remainder? what is left over when you divide ?

Answer 14

you know like in elementary school, 4 goes in to 22 5 times with a remainder of 2 for example

Answer 15

Right, it's 6

Answer 16

ok right
so now all you need is to evaluate the function at 6

Answer 17

because it is periodic, it will be the same at 6, 6+8, 6+2*8, 6+3*8, ... 6+7*8 = 62

Answer 18

Ohh
That makes so much more sense
Thank you so much
