Answer:
It means that when x = 3, y = 1, obviously when the first function expression takes 3, y = 1
Answer:
Width of the rectangle = 13.16 ft
Length of the rectangle = 34.33 ft
Step-by-step explanation:
Let the width of the rectangle = k ft
So, the length of the rectangle = (2k + 8) ft
Perimeter of the rectangle = 95 ft
PERIMETER OF THE RECTANGLE = 2(LENGTH +WIDTH)
⇒ 2( k+ (2k+ 8)) = 95
or, 2( 3k + 8) = 95 ⇒ 6k + 16 = 95
or, 6k = 95 - 16 = 79
⇒ k = 79/ 6 = 13.16
So, the Width of the rectangle = k = 13.16 ft
Now, Length of the rectangle = 2(13.16)+ 8 = 34.33 ft
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.
<h3>What is the surface area of a truncated prism?</h3>
The <em>surface</em> area of the <em>truncated</em> prism is the sum of the areas of its six faces, which are combinations of the areas of rectangles and <em>right</em> triangles. Then, we proceed to determine the <em>surface</em> area:
A = (12 cm) · (4 cm) + 2 · (3 cm) · (4 cm) + 2 · (12 cm) · (3 cm) + 2 · 0.5 · (12 cm) · (5 cm) + (5 cm) · (4 cm) + (13 cm) · (4 cm)
A = 48 cm² + 24 cm² + 72 cm² + 60 cm² + 20 cm² + 52 cm²
A = 276 cm²
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.
