Step-by-step explanation:
a^2 + b^2 = c^2
6 = b
c= 8
a=?
now u just replace
a^2 + 6^2 = 8^2
a^2 + 32 = 64
a ^2 = 64-32
a^2 = 32
a = 5.65685424949
if you rounded
a = 5,7
Answer:
See the graphic I made
Area of Section A = 4 *1 = 4 square centimeters
Section B = 4 * (3 + 4) = 28 sq cm
Section C = 3 * (2 + 3 + 4) = 27 sq cm
Total Area = 4 + 28 + 27 = 59 square centimeters

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
