Answer:
the radius is half of the diameter so that would mean that the radius is 1 mile.
Step-by-step explanation:
Answer:
P = 4
Step-by-step explanation:
2 x 4 is 8
so 13 - 8 = 5
1)
-2(3x+4)=-6x-8≠-6x+8
2)
2(-3x+4)=-6x+8
3)
5(x+1)-11x+3=5x+5-11x+3=-6x+8
4)
x+2-7x+6=-6x+8
5)
8-6x=-6x+8
Answer: The expressions 2,3,4 and 5 are equivalents.
Step-by-step explanation:
98 = 188t - 16t^2
-16t^2 + 188t = 98
-16t^2 + 188t - 98 = 0
8t^2 - 94t + 49 = 0
Use the quadratic formula with a = 8 , b = -94 , c = 49 to get the solutions
t = [(47 - root 1817) / 8]≈ 0.55
and
t = [(47 + root 1817) / 8] ≈ 11.20
