Answer:
Step-by-step explanation:
We are given equation of parabola as
we can also write as
now, we can compare
and find a , h , and k
a=1
h=0
k=0
now, we can use focus formula
now, we can plug values
The answer is 80! If you ever see any angle like that where it’s just two lines (I don’t know how to explain it/forgot what it’s called) it will be the same as the other angle.
x = -8
Step-by-step explanation:
Step 1: Subtract 1 from both sides
Divide both sides of the equation by -10
Answer:
Section lines
Step-by-step explanation:
Sectioning is the process of cutting a surface by an imaginary plane, the view of the surface that is cut is shown in the section view.
Section lines are used to indicate where an imaginary cutting plane cuts a material. The imaginary cut is then represented using section lines which are usually thin, crosshatched.
Section lines shows the surface that have been cut by the cutting plane. There are different ways of sectioning such as full section, half section, off set section and so on
