<u>Story Problem</u>
Mr. Bill Gates bought a house in Italy for and a house in Canada for
. What is the total cost of the two houses?
we know that
The total cost is the sum of the cost each house
so
therefore
the answer is
The total cost is
Is the equation a linear function or nonlinear function?
2 answers:
Answer:
Nonlinear function
Step-by-step explanation:
<u>To know</u> - linear vs nonlinear
[] A linear function is a straight line. Examples such as y=3x + 3 or y= -4x + 1
[] A nonlinear function is not a straight line. This is usually because it contains exponents.
[] Since the function has a square root, and there are two answers for each square root problem, this is not a linear function.

Answer:
<em>The area of the shaded part = 61.46</em>
<em />
Step-by-step explanation:
Assume the hypotenuse of the triangle is c (c>0)
As the triangle inscribed in the semi circle is the right angle triangle, its hypotenuse is equal to the diameter of the circle.
The hypotenuse of the triangle can be calculated by Pythagoras theorem as following:
=> c = 10
So that the semi circle has the diameter = 10 => its radius = 5
- The total area of 2 semi circles is equal to the area of the circle with radius =5
=> The total area of 2 semi circles is: x
= 25
- The area of a triangle inscribed in the semi circle is: 1/2 x a x b = 1/2 x
x
= 20
=> The area of 2 triangles inscribed in 2 semi circles is: 2 x 20 = 40
- The area of the square is:
=
It can be seen that:
<em>The area of the shaded part = The area of the square - The total area of 2 semi circles + The total are of 2 triangles inscribed in semi circles </em>
<em>= 100 - 25</em><em> + 40 = 61.46</em>
