"A scale factor is a number which scales, or multiplies, some quantity. ... In the field of measurements, the scale factor of an instrument is sometimes referred to as sensitivity. The ratio of any two corresponding lengths in two similar geometric figures is also called a scale factor." (not my wording but i hope this helps)
Answer:
since M lies between point A and B , we came to know that,
M(4,6) =(x,y)
A(-2,-1)=(x1 ,y1)
B( _, _ )=(x2,y2)
Now using mid point formula,
x=x1×x2÷2 y=y1+y2÷2
so, point B is (10,13)
Answer:
The height of triangle EFG is 9 units
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the area of a square ABCD
The area of a square is equal to

where
b is the length side of the square
we have

substitute

step 2
Find the height of triangle EFG
The area of triangle EFG is equal to

where
b is the base of triangle
h is the height of triangle
we have

---> area of triangle EFG is the same that the area of square ABCD
substitute the given values in the formula

solve for h

therefore
The height of triangle EFG is 9 units
It is in simplest form. Decimal form is 14.4
