Answer:
FALSE !
Step-by-step explanation:
Answer:
- 2–9 7π/6
- 3–7 2π/3
- 4–6 π/3
- 1–4 π/2
- 5–10 5π/6
Step-by-step explanation:
The angle between numbers on an analog clock is π/6 radians. So, the angles of interest are ...
2 to 9 : seven numbers : 7π/6 radians
3 to 7 : four numbers : 4π/6 = 2π/3 radians
4 to 6 : two numbers : 2π/6 = π/3 radians
1 to 4 : three numbers : 3π/6 = π/2 radians
5 to 10 : five numbers : 5π/6 radians
Let the length of one of the diagonals be 2x and the other be 2y, then
cos (76/2) = x/10
x = 10 cos 38 = 7.88 cm
sin (76/2) = y/10
y = 10 sin 38 = 6.16 cm
f(5) means to replace the x in the equation with 5.
f(5) = 8(5) - 3
f(5) = 40 - 3
f(5) = 37
