Answer:
xsin∅
Step-by-step explanation:
If the ladder is <em>x foot long</em>, and it can safely make a <em>maximum angle ∅</em> with the floor, then, the maximum height it can reach will be xsin∅
Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.
Answer: She has $15
Step-by-step explanation:
20*0.75=15
Answer:
area = 50.27
circumference = 25.13
Step-by-step explanation:
area
pi x radius²
pi x 4² = 50.27
circumference
pi x diameter = 8 pi
8 pi = 25.13
