According to the Pythagorean theorem:
a² + b² = c²
a = 4
b = 1
c = ?
4² + 1² = c²
c² = 16 + 1
c² = 17
c = √17
0.7=7/10
0.8=8/10
0.75=3/4 this is between 0.7 and 0.8
Answer:
. The biggest common factor number is the GCF number.
So the greatest common factor 3 and 9 is 3.
Step-by-step explanation:
(f∘g)(3) = f(g(3))
Find g(3) by substituting x=3 in g(x)
g(x)=x²-1
g(3)=3²-1
g(3)=9-1
g(3)=8
f*g(3) = f(g(3)) = f(8)
find f(8) by substituting x=8 in f(x):
f(x)=2x+3
f(8)=2(8)+3
f(8)=16+3
f(8)=19
So f∘g(3) = 19
