Answer:20,965
Step-by-step explanation:
Answer:
3769.57
Step-by-step explanation:
the perimeter of semicircle is
P = d + πd/2
251.86 = d + (3.14d/2)
multiply both side with 2
503.72 = 2d + 3.14d
503.72 = 5.14 d
d = 98 miles
d is diameter, then the radius is 98 : 2 = 49
Area of semicircle
A = ½ π r²
A = 0.5 x 3.14 x 49²
A = 3769.57 miles²
-3x = -3 because you would multiply one of the equations by -1 to eliminate y.
Total possible outcome = 36
Outcome with sums is 5 = 4
{1, 4} (2, 3} {3, 2} {4, 1}
P(getting sum = 5) = 4/36 = 1/9
Answer: 1/9
Put 2 where p is, then do the arithmetic.
f(2) = 3×2 -2
f(2) = 6 -2 = 4
The output of the function is 4 when the input is 2.
