Answer:
Step-by-step explanation:
Since we are to show by Pythagoras that the square will fit inside the circle without touching the edge of the circle , this means that we must find the value of the length of the diagonal of the square using Pythagoras.
For the square to fit in without touching the edge of the circle , this means that the diagonal of the square must be less than the diameter of the circle.
Length of the square is 5cm.
Recall Pythagoras theorem: it states that
the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides
= +
= 25 + 25
= 50
Take the square root of both sides , that is
D =
D = X , since 50 = 25 x 2
D = 5
D ≈ 7.07
Note that the diameter of the circle given is 9 and D < 9 , we can therefore conclude that the square will fit inside the circle without touching the edge of the circle since the diagonal of the square is less than the diameter of the circle
Answer:
Explanatory variable = Effect of music
Response variable = Memory response
Step-by-step explanation:
An explanatory variable, also known as independent variable, is a variable that can be manipulated so as to analyse their effect on another variable. It is used to predict or explain differences in another variable.
Response variable is a variable whose variation depends on other variable. It is also called a dependent variable.
In this analogy, since the effect of music on memory is what is to be known, music is the explanatory variable while memory is a response variable.
