A triangle pyramid has a base with an area of 11.3 square meter, and lateral faces with bases of 5.1 meters and height of 12 meters. Enter a expression that can be used to find the surface area of the triangle pyramid . Grade 6 go math chapter11 pre test

Thank you bye!!!

229.41

Step-by-step explanation:

Well you need to multiply 11.3 times 4.5 per each triangle

Also you need to find the base which is a square

So 5.1 times 5.1 which is technically 5.1 squared. You add from there

EQUATION: 4(11.3 x 4.5) + 5.1 squared  

You should get 229.41

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.
