Answer:

The graph that shows the correct sum is:

Graph B

Step-by-step explanation:

We are given a graph of a function f(x) as a straight line that passes through (0,2) and (2,0).

Hence, the equation of f(x) is:

$y=-x+2$

Also the graph of g(x) is a upward open parabola with vertex at (0,-3)

Hence, the equation of g(x) is:

$y=x^2-3$

Now the sum function i.e. (f+g)(x) is given by:

$(f+g)(x)=f(x)+g(x)$

Hence,

$(f+g)(x)=x^2-x-1$

Hence, the graph that denotes this function is:

Graph B.

For circle O, mCD=125° and m

Burka [1]

CA is a diameter of the circle, so $m\widehat{AC}=180^\circ$ , which means $m\angle AOB=m\angle AOD=m\widehat{AD}=180^\circ-m\widehat{CD}=55^\circ$ . Then $m\boxed{\angle ABO}=90^\circ-55^\circ=35^\circ$ .

This means $m\angle CBO=55^\circ-35^\circ=20^\circ$ . Also, if $m\angle AOB=55^\circ$ , then $m\angle BOC=180^\circ-55^\circ=125^\circ$ , which in turns tells us that $m\boxed{\angle BCO}=180^\circ-20^\circ-125^\circ=35^\circ$ .
