Tony is using the numbers 13 , 1 , 8 ,5
-he can use brackets, +, -, ÷ as much as he wants
-he cannot use any number more than once
-he cannot use powers
-he cannot put numbers together e. g 185
what is the biggest number he can make?
must show how he can make this number

answer:

85131

Step-by-step explanation:

possible numbers are

11385,

11358,

13185,

13158,

18135,

18513,

15138,

15813,

but biggest number is 85 131

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
