Answer: B.) 62
sum of interior angles of quadrilateral = 360
lines DB and DA are tangent to the circle, so they're at a right angle to the lines OB and OA respectively. so to find mBOA = 360 - 56 - 90 - 90
so mBOA = 124
mBCA = (1/2)mBOA
mBCA = (1/2)(124)
mBCA = 62°
Given:
The graph of a function.
To find:
The domain and range of the function.
Solution:
We have, the graph of a function and we need to find the domain and range of the function.
We know that, domain is the set of input values (x-values) and range is the set of output values (y-values).
From the given graph it is clear that function is defined for all values of x except x=0 because as x tends to 0 the function tends to negative or positive infinite. So, domain can be any real number except 0.


From the given graph it is clear that the value of function can be any real number except y=0. So, range can be any real number except 0.


Therefore, the correct option is B.
7) Larger number= 30
Smaller number= 18
8) He bought 4 videogames and 11 movies.
Answer:
140.42 US dollars
Step-by-step explanation:
250x1.3687=342.175
342.175-150=192.175
192.175/1.3687=~140.41
