R = 13.1
so
<span>diameter = 13.1 x 2 = 26.2 km
</span>circumference = 2 pi r = 26.2 pi km
or
circumference = 26.2 x 3.14 = 82.27 km
Answer:
f(g(2))=84
Step-by-step explanation:
Step one:
Given data
f(x)= x*2 +3
g(x) = 4x + 1
Step two
Let us find g(2) first then we proceed to find f(g(2))
g(2)=4(2) +1
g(2)=8+1
g(2)=9
Since g(2)=9
f(g(2))=x*2 +3
f(g(2))=9*2 +3
f(g(2))=81+3
f(g(2))=84
Y= -1.7x + 8.5
10( Y = -1.7 x + 8.5)
10Y = -17x + 85
+17x
17x + 10Y = 85
Answer:
y=7
Step-by-step explanation:
Since they are all congruent angles this means that the sides are equal too.
I believed it’s the second one.
