Answer: I think it is 10364 or 10248 because when i put it in a calculator I got 8803.4 or 10296
Step-by-step explanation:
Let's first rewrite it in vertex form.
Start by completing the square.
y = x² + 4x + 4 - 4 - 1
y = (x + 2)² - 5
(x + 2)² = y + 5
Now, 4a = 1; a =

So, the vertex form is (x + 2)² = 4(

)(y + 5)
So, we know that the vertex is at (-2, -5).
Since it's a concave up parabola, we just have to change the y-value to find the focus.
∴ F(-2, -5 +

)
F(-2,

)
This is how you solve it, and here is the answer!
Answer:
226
Step-by-step explanation:
You first have to find the volume of the cylinder, which you would do 3 squared, which is 9, times 8, which is 72, and then times pi, which gives you 226.1946711. Since they want the closest volume to that number, it would just be 226. If you are confused on the equation, the equation for the volume of a cylinder looks like this:
, where r is the radius and h is the height.
Answer:
3(16 + (─40) + 4) = -60
(─10 + 18) × (─1) = -8
Step-by-step explanation:
3(16 + (─40) + 4)
PEMDAS:
3(16+(-40)+4)
3(-24+4)
3(-20)
-60
(─10 + 18) × (─1)
PEMDAS:
(-10+18) x (-1)
8 x -1
-8
These are your answers
Hope this helps!
