The steps in construction angle bisector and perpendicular bisector are shown in the diagram below.
The first diagram is for angle bisector and the second diagram is for the perpendicular bisector.
Answer:
P = 0.14t +2.25
Step-by-step explanation:
The statement that "the price of a school lunch ... has risen at a constant rate" is telling you that the price can be modeled by a linear equation. If P is the price, and t is years after 2012, you are given two points on the line:
(t, P) = (0, 2.25) and (7, 3.20)
You can use these points to find the equation of the line in the usual way.
m = (y2 -y1)/(x2 -x1) . . . . . . slope of a line through (x1, y1) and (x2, y2)
m = (3.20 -2.25)/(7 -0) = 0.95/7 ≈ 0.14
The first point tells you the equation intercept, so the relationship between P and t is ...
y = mx +b . . . . . . . m = slope; b = y-intercept. We're using (t, P) for (x, y).
P = 0.14t +2.25
Answer:
x = 49.5°
Step-by-step explanation:
∠ABC = 90°
∠CBD = 45%∠ABC
∠CBD = 0.45(90)
∠CBD = 40.5°
x = ∠ABC - ∠CBD
x = 90 - 40.5
<u>x = 49.5°</u>

Answer: 625</h3>
Work Shown:
The set {A,B,C,1,2} has five items. There are four slots to fill.
So we have 5^4 = 5*5*5*5 = 625 different possible passwords where the characters can be repeated.
