Answer: hey man, the answer to this question is A:each side of the original square is 1/4 the length of the scale model.
Step-by-step explanation: It’s A because if if was created by using the factor of 4, then the original side must have been 2 because 8 divided by 4 is 2. and 2 is 1/4 of 8. Hope this helps!

notice, Papa Bear is 18inches in diameter, but radius is half that
and "edge per dollar" simply means, how much circumference per dollar

Answer:
Subtract 2 2 from 2 2 . Add x x and 0 0 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x4−2 f - 1 ( x ) = x 4 - 2 is the inverse of f(x)=4x+8 f ( x ) = 4 x + 8 .

Answer:sin (140°)
Explanation:Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.
Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°
Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.
Therefore:
sin97°cos43°+cos97°sin43°
= sin (97°+43°)
= sin (140°)
Hope this helps :)
