hope this helps
It's 6/12 then 1/2. Good luck
Answer:
c(n) = 4n +20
let m = c(n)
m= 4n +20
make n the subject
<u>m</u><u> </u><u>-</u><u>2</u><u>0</u><u> </u><u> </u> =n
4.
inverse function of c(n)= <u>n-20</u><u> </u>
4
It is a must that one replaces the m with the n in order to get the final answer
Answer:
23
Step-by-step explanation:
multiply the cost by 3
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.
