Answer: The answer is: f(x) = 2x^2 + 40x + 200
Explanation:
Given: x is the width of the Artwork
Let W be the Width of the Frame
Let L be the Length of the Frame
Width = x + 10
Length = Width * 2, so by substitution, Length = 2(x + 10)
Area = Width * Length
By substitution:
Area = (x + 10) * 2(x + 10)
f(x) = (x + 10) * (2x + 20)
f(x) = 2x^2 + 20x + 20x + 200
f(x) = 2x^2 + 40x + 200
To test this, if a picture 8" wide is put in this frame, the width would be 8+10 or 18 inches. The length would be twice the width, or 36 inches. The Area is 18 x 36 = 648.
Using the formula:
f(8) = (2 * 8^2) + (40 * 8) + 200
f(8) = (2 * 64) + 320 + 200
f(8) = 128 + 320 + 200
f(8) = 648
The correct answer is B) coal.
The industry that was influenced by the steam engine and first allowed for technological innovations in transportation was the coal industry.
The steam engine used coal to work. This new invention served to produce energy in a most powerful way than other devices.
The invention of the steam engine changed the way people produced goods in industries and in the transportation industry. Indeed, this invention transformed industries.
New machines in the fabrics helped to introduce the concept of mass production to produce goods more efficiently and at better costs. In the transportation industry, the steam engine allowed the development of railroads as the best means of transportation in the 1800s.
