Not only in mathematics, scientific proof also are required in the other field of science. Also maths proofs are of particular structure, containing steps and logics. So proving is like doing science, it is science. That's why it is important to prove.
An inaccurate proof leads to errors, or stating results that are not accurate.
Example 1:
If the derivative of a function is negative, then the function is decreasing.
Example 2:
The sum of the measures of the angles of any triangle is 180°.
Example 2:
Given a triangle whose vertices are on a circle and one side is the
diameter of the triangle, then the triangle is right angled.
Answer:
G. 0.08
Step-by-step explanation:
It is actually 0.8 but putting a zero before 8 is fine.
0.0008=0.8
0.8000=X
Area(A)=192ft^2
Width (W)=?
Length (L)=3W
First we must find what the width and length are to find perimeter (P=2L+2W).
A=LxW
192=(3W)(W)
192=3W^2
192/3=3W^2/3
64=W^2
8=W can only use positive solution of 8 because distance is positive.
L=3W=3(8)=24
P=2L + 2W
P=2 (24)+2 (8)
P=48+16=64ft
