Integrated 1 Week 5 (September 21-25) 1.2.1 What is the function?
Function Machines
In the previous lesson, you used equations relating two variables (like y=3-2x) to make graphs and find
information. Today you will look more closely at how what equation do I write? equations that relate two variables help establish a function
between the variables. You will also learn a new notation to help represent these functions.
1-33. ARE WE RELATED?
Examine the table of input (x) and output (y) values below. Is there a relationship between the input and output
values? If so, write an equation for this relationship.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

is should be y = 5x

step-by-step explanation:

correct me if im wrong

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
