I think the answer is 3. Plug in the value of x (1) into the f(x). Then solve to find that f(x)= -1, then plug in -1 to x in g(x) to get that g(f(x))=3
Answer:
4 cm, if you subtract 9 from 13 you get four.
Answer: 16/81
Step-by-step explanation:
2/3 × 2/3 × 2/3 × 2/3
= 16/81
All you have to do is cross multiply!
Ur answer to the first one is 9/10
Ur answer to the second ine is 4/5
Circumference of the outer circle = 2πr = 2π(6) = 12π
circumference of the outer arc = 120/360 x 12π = 12.57cm
circumference of the inner circle = 2πr = 2π(5) = 10π
circumference of the inner arc = 120/360 x 10π = 10.47 cm
Difference in length = 12.57 - 10.47 = 2.1cm (1 d.p.)
Answer: 2.1cm
