Answer:
44.8
Step-by-step explanation:
cos α = adjacent leg/hypotenuse
cos 48° = 30/x
x = 30/(cos 48°) = 44.8
Answer:
See below
Step-by-step explanation:
then f(x)=0 if x<0 and f(x)=x if x≥0.
When x→-∞, f is the constant function zero, therefore
. When x→∞, f(x)=x and x grows indefinitely. Thus 
f is differentiable if x≠0. If x>0, f'(x)=1 (the derivative of f(x)=x) and if x<0, f'(0)=0 (the derivative of the constant zero). In x=0, the right-hand derivative is 1, but the left-hand derivative is 0, hence f'(0) does not exist,
f'(x)>0 for all x>0. Therefore f(x) is strictly increasing on the inverval (0,∞).
Answer:
1 1/3 cups
Step-by-step explanation:
To double, multiply by 2
2/3 * 2
4/3
Change to a mixed number
3/3 + 1/3
1 1/3 cups
Answer:
x= 15 is the answer

Answer:
2.51 m
Step-by-step explanation:
100 cm = 1 m
(251 cm) / (100 cm) = 2.51 m
