How does 6+(-3) equal 3? I don't understand what I have to do to get that answer.
WITCHER [35]

Answer:

look at the explanantion <33

Step-by-step explanation:

so negative numbers are basically numbers with minus signs in front of them. So when you add a negative number, its basically like subtracting a number. so by adding negative three, youre subtacting 3.

6-3 is 3. does that make sense?

If a large cylinder has a volume of 28260 cubic cm, how many cylinders can be filled out of the large cylinder if the small cyli
inysia [295]
Hi,

To find the number of small cylinders that fit inside the big cylinder. You need to divide volume of small cylinder with the volume of big cylinder. We do this by using formula to calculate volume of cylinder:


v = \pi \times  {r}^{2}  \times h


To find radius just divide diameter with 2.

v = \pi \times   {2}^{2}  \times 6 \\ v = \pi \times 4 \times 6 \\ v = \pi \times 24 \\ v = 3.14 \times 24 \\ v = 75.4 {cm}^{3}


Now just division:

28260 \div 75.4 = 374.8

Answer: You could fit 374.8 smaller cylinders inside a big cylinder.

Hope this helps.

Find the domain of the function using interval notation.<br> <img src="https://tex.z-dn.net/?f=f%28x%29%3D8%5Csqrt%7Bx-9%7D" id=
Irina18 [472]

Answer:

D_{f(x)} = [9, \infty)

Step-by-step explanation:

Here we have the square root of a function, in the following format:

f(x) = \sqrt{g(x)}

For the square root, and roots of even numbers(root of 4, 6, ...), we have the following condition in the domain

g(x) \geq 0

In this problem, we have that:

f(x) = 8\sqrt{x-9}

So

x - 9 \geq 0

x \geq 9

So the domain is

D_{f(x)} = [9, \infty)
