Answer:

Step-by-step explanation:
There are many methods to find the vertex of a quadratic function. The method that I will show you is by using the roots of the function
In the case of this function, the roots are
..
The vertex of a function will always be directly between these roots. The number that is directly between -1 and -3 is -2. This means that the x-value of our vertex is -2.
Now that we have the x-value, we can plug this into the function in order to get our y-value.

We have found that our y-value is -2. This means that the coordinates of the vertex are 
When you multiply by 1/10 you normally add another 0:
1/10 * 0.092=0.0092
Answer:
Step-by-step explanation:
10 feet x 12 feet x 8 feet = 960 cubic feet
Answer:
2390.7 square meters
Step-by-step explanation:
(semicircle area) 30.5/2 = 15.4
15.4 x 15.4
= 232.5625 x 3.14
= 730.24625 x 2 = 1460.4
(square area) 30.5 x 30.5 = 930.25
930.25+ 1460.4= 2390.7 square meters
