Answer:
A
Step-by-step explanation:
It is A, when they each make 10 calls.
This is because on the graph, you can see that they meet up (after the y-intercepts) at the x-axis of 10.
Hope this helped!
The vertex angle bisector divides the triangle into two congruent right triangles. The sine of half of the vertex angle will be half of the base divided by the side (from the definition of the sine of an angle). Then the total vertex angle is ...
α = 2×arcsin(3.5/5) ≈ 88.9°
_____
Using the Law of Cosines, the vertex angle can be found as
arccos((7^2 -5^2 -5^2)/(-2*5*5)) = arccos(1/50) ≈ 88.9°
Answer:
D) The graph of the line shifts horizontally left 5 units.
Adding a number, n, inside of the parenthesis with x would move the parent function n units to the left.
