Let's try to complete the squares.
The x-part starts with
, which is the beginning of
. So, we'll think of
as 
Similarly, we have that

So, the equation becomes

Now we have writte the equation of the circle in the form

When the equation is in this form, everything is more simple: the center is
and the radius is
.
Answer:
1.25cm
Step-by-step explanation:
<em>Complete question:</em>
The prism has a volume of 35 cm cubed workout h, the height of the triangular cross section
<em>length=7cm</em>
<em>width = 4cm</em>
<em></em>
The volume of the prism is expressed as;
Volume = Base Area * Height
Given
Volume of the prism = 35cm^3
Base Area = length * width
Base Area = 7cm * 4cm
Base Area = 28cm^2
Substitute the given values into the formula
35 = 28* Height
Cross multiply
35 = 28 * Height
35 = 28 Height
Height = 35/28
Height = 1.25cm
Hence the height of the triangular cross section is 1.25cm
Answer:
C
Step-by-step explanation:
