Answer: 9.9 Original answer is 10.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that g is a function from g : {1, 2, 3} ->{1, 2, 4, 8}
by the function

i.e. we have 
Range = {2,4,8} Since there is an extra element 1 in the co domain which is not in range , g is not on to
But g is one to one as 1,2,3 have different images.
Answer
Multiplication
Step-by-step explanation:
answer : False
The measure of a tangent-tangent angle is one - half the difference of the measures of the intercepted arcs.
The diagram is attached below
AB and BC are the two tangents
By exterior angle theorem
∠3 = ∠2 + ∠4
So ∠2 = ∠3 - ∠4
Now we find angle 3 and 4, we know when a chord and tangent intersect at a point then the measure of angle is one half of measure of intercepted arc
∠3 =
∠4 = 
∠2 = ∠3 - ∠4
∠2 =
- 
∠2 = 
The measure of a tangent-tangent angle is one half the difference of the measures of the intercepted arcs.
