By definition of <em>surface</em> area and the <em>area</em> formulae for squares and rectangles, the <em>surface</em> area of the <em>composite</em> figure is equal to 166 square centimeters.
<h3>What is the surface area of a composite figure formed by two right prisms?</h3>
According to the image, we have a <em>composite</em> figure formed by two <em>right</em> prisms. The <em>surface</em> area of this figure is the sum of the areas of its faces, represented by squares and rectangles:
A = 2 · (4 cm) · (5 cm) + 2 · (2 cm) · (4 cm) + (2 cm) · (5 cm) + (3 cm) · (5 cm) + (5 cm)² + 4 · (3 cm) · (5 cm)
A = 166 cm²
By definition of <em>surface</em> area and the <em>area</em> formulae for squares and rectangles, the <em>surface</em> area of the <em>composite</em> figure is equal to 166 square centimeters.

Answer:
f(g(-3)) = 5
Step-by-step explanation:
To find f(g(x)) just plug in g(x) for x in f(x)
f(x)= x - 4
f(g(x)) = (6 - x) - 4
f(g(x)) = 6 - x - 4
f(g(x)) = 2 - x
Now to find f(g(-3)) we plug in -3 for x.
f(g(-3)) = 2 - (-3)
f(g(-3)) = 2 + 3
f(g(-3)) = 5
Answer:
y ≈ 6.7
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26.5° = 
= 
( multiply both sides by 15 )
15 × sin26.5° = y , then
y ≈ 6.7 ( to 1 dec. place )
