Answer:

BD = 3.75 units

Step-by-step explanation:

Given AD is an angle bisector then it divides the opposite side into segments tat are proportional to the other 2 sides, that is

\frac{AB}{AC} = \frac{BD}{CD} , substitute values

\frac{6}{8} = \frac{BD}{5} ( cross- multiply )

8 BD = 30 ( divide both sides by 8 )

BD = 3.75 units

Answer:

<B = <ABC = 107°

Step-by-step explanation:

<CAB = 32° (property of isosceles triangle)

<ACB = 41° (property of isosceles triangle)

<ABC = ?

<ABC + <ACB + < CAB = 180° (sum of angles of triangle)

<ABC + 41° + 32° = 180°

<ABC + 73° = 180°

<ABC = 180° - 73°

<ABC = 107°

Period would be the distance between 2 peaks

looking at the graph there is a peak on x= 1 and then a peak on x= 4
4-1 = 3 so the peak is 3

the amplitude is the midpoint between the highest point and lowest point
 on the graph
 the high point is y=1 and the low point is y = -2
1 + -3 = 3 spaces, midpoint = 3 / 2 = 1.5 so the amplitude = 1.5

the answer is the first one.
