Answer:
The answer is 20pi
Step-by-step explanation:
perimeter of a semicircle = pi* radius
perimeter of first semicircle = 5.pi
perimeter of second semicircle = 5.pi
perimeter of third semicircle = 10. pi
total perimeter = 5pi +5pi + 10pi
= 20pi
Answer:
Greater Than 1
Step-by-step explanation:
The difference cos(120° - 45°) is most likely the form you would use with that formula.
_____
The "difference" cos(30° + 45°) could also be used, where 45° is rewritten as -(-45°), or 30° is rewritten as -(-30°).
Answer:
C
Step-by-step explanation:
when x is negitive, y has an asitope of 0 so not a
when x is negitive, y has an asitope of 0 so not b
when x is positive, y does keep going down so c
when x is positive, y does keep going down and doesn't seem to be approching 0 so not d
