1 answer:
ZanzabumX [31]3 years ago
8 0

Answer:

1. False 2. True

Step-by-step explanation:

For a geometric sequence,

\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}

1. The sequence is :

3, 13, 23, 33,...

\dfrac{13}{3}\ne \dfrac{23}{13}

It is not geometric. It is false

2. The sequence is :

5, -25, 125, -625

\dfrac{-25}{5}=\dfrac{125}{-25}\\\\-5=-5

So, the sequence is geometric as the common ratio is same. It is true.

A rectangular tank is 100cm, 30cm wide and 12cm deep. The volume of liquid it will hold is?
konstantin123 [22]
Assuming that you mean 100cm in length, I think I know the answer, but message me if I’m wrong so that I can correct myself!!!

Volume is L • W • H where L is length, W is width, and H is height.

To find the volume you have to multiply all the dimensions, so 100 * 30 * 12 = 36,000, and since its 3 dimensional we use cm^3 which is centimetres cubed.

Y-3=(x+2)^2<br><br> Please explain how you graph this and find the vertex and axis of symmetry
bija089 [108]
Okay so I attatched pictures of my work. I would just graph it by plugging in x-values on either side of the vertex into the equation. For example, the vertex is at (-2,3). So try plugging x=-5 and x=1 into the equation (y=a(x-h)^2 +k).
y=(x+2)^2 +3
y=((1)+2)^2 +3=(3)^2+3= 9+3= 12 
Now you can plot the vertex (-2,3), the point (1,12), and (-5,12). From there just connect the dots and you should get a graph that looks similar to the last picture I attached. Hope this all made sense sorry it was so wordy I just wasn't sure how much you knew or didn't know. So, I thought it would be better to explain it all rather than not enough.
