Answer:
139.25 m²
Step-by-step explanation:
Area of the square = 10 * 10 = 100 m²
Radius of the semicircle = 5 m
Area of the semicircle = π(5)²/2 = 39.25 m²
Total area = 100 + 39.25 = 139.25 m²
Explanation:
a)


b) First, we have that

On the other hand,

Therefore, both expressions are equal. This makes sense, because selecting k elements from a group of n is the same than specify which elements you will not select. In order to specify those elements you need to select the n-k elements that will not be selected. Hence, each time you are selecting k from n, you are also selecting n-k from n, and from that reason both combinatorial numbers are equal.
Answer:
-35/3
Step-by-step explanation:
-2(3x-2) + 3x + 3 = 34
-6x-4+3x+3=34
-3x-1=34
-3x=35
x=-35/3
I believe it should be 1.296 miles
