Answer:
I think is f(bx)=2x^2
Step-by-step explanation:
The number of stickers John and Ken have in the end is 6 and 18 respectively.
<h3>How to write and solve equation?</h3>
let
- Ken stickers = x
- John stickers =3x
New stickers
x + x - 12 = 3x + 5x
2x - 12 = 8x
-12 = 8x - 6x
-12 = -2x
x = 12/2
x = 6
So,
Ken stickers = x
= 6 stickers
John stickers = 3x
= 3 × 6
= 12 stickers

Answer:
12/13
Step-by-step explanation:
Given that MN = 5, NO = 12, and MO = 13, find cos O.
Since the reference angle is P, hence;
MN is the opposite = 5
MO is the hypotenuse = 13 (longest side)
NO is the adjacent = 12
Cos O = adj/hyp
Substitute the given values
Cos O = 12/13
Hence the value of Cos O is 12/13
I'm pretty sure its B) 8 × 10^0
