Answer:
A. 251.33 cubic units
Step-by-step explanation:
volume of cone = (1/3) * area of base * height
Since your base is a circle, the area of the base is pi * r^2.
Now we have
volume of cone = (1/3) * pi * r^2 * h
volume of cone = (1/3) * 3.14159 * 4^2 * 15
volume of cone = 251.33 cubic units
Hey there!
It can be both. It's a multiple of 8 because 8 times 5 is 40, but it's also a factor of 120 because 80 times 3 is 120.
Hope this helps!
Answer: Possibly -4

But wait for others to check I’m not fully sure
Answer:
y = (x + 3)² - 4
The vertex is a minimum at (-3, -4)
Step-by-step explanation:
Step 1: Isolate xs
y - 5 = x² + 6x
Step 2: Complete the square
y - 5 + 9 = x² + 6x + 9
y + 4 = (x + 3)²
Step 3: Convert to vertex form
y = (x + 3)² - 4
To find your vertex, <em>(h, k) </em>is your vertex, so (-3, -4). To see whether or not it is a max or a min, check <em>a </em>to see if it is positive or negative. Since <em>a </em>is positive, it is a minimum.
