David is performing the following construction. based on the markings that are present, what construction is he performing?
bisecting an angle
bisecting a line segment
copying an angle
copying a line segment

Bisecting an angle

Step-by-step explanation:

David first draw an angle CAB i.e

Then draw an arc cutting AC at D and AB at E .

With E as centre , draw an arc then with D as centre draw an arc

Both the arcs will intersect at some point .

If we join point A to this intersecting point , we get an angle bisector of

So, based on the markings that are present , he is actually bisecting the angle.

An angle bisector is a line or line segment which bisects an angle into two equal parts .

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
