Answer:
a(n) = a(1) + 6(n -1)
Step-by-step explanation:
The common difference here is 6. 1 + 6 = 7; 13 + 6 = 19; and so on.
Thus, the function in question is a(n) = a(1) + 6(n -1).

Answer:
41.13 sq m
Step-by-step explanation:
area of square = 4² = 16
there are two quarter-circles which equals one semicircle
area of semi-circle is πr²/2
A = 4²π/2 = 8π = 25.13
add together: 16 + 25.13 = 41.13
Answer:
You can determine the type of triangle using the following facts related to the converse of the pythag theorem
if a^2 + b^2 > c^2, then it is an obtuse triangle
if a^2+b^2<c^2, then it is an acute triangle
finally, if a^2+b^2=c^2, then it is a right triangle
<u><em>NOTE THAT C ALWAYS EQUALS THE LONGEST LENGTH OF THE TRIANGLE!!!</em></u>
Answer:
Step-by-step explanation:
<u>Area of circle:</u>
<u>Area of α degree sector:</u>
<u>The shaded area is:</u>
- S = π*10²×(72*2)/360 = 100π×144/360 = 40π
