Answer:
<h2><u>
D. -3</u></h2>
Step-by-step explanation:
The y-intercept of an equation is a point where the graph of the equation intersects the Y-axis. There are several ways to find the y-intercept of an equation, depending on the starting information you have.
<u>How to find the Y-Intercept from the Slope and Point.</u>
Write down the slope and point. The slope or "rise over run" is a single number that tells you how steep the line is. This type of problem also gives you the (x, y) coordinate of one point along the graph. Skip to the other methods below if you don't have both these pieces of information.
- Example 1: A straight line with slope 2 contains the point (-3,4). Find the y-intercept of this line using the steps below.
Area of circle = pi r^2 = 78.54
r^2 = 78.54 / pi = 25
r = 5 inches
Each line from centre of the circle to a point on the hexagon = 5 ins
so consider one of the 6 congruent triangles formed from these lines:-
Vertex angle = 60 degrees
sin 30 = 0.5s / 5 (where s = one side of the hexagon).
0.5s = 5*0.5 = 2.5
s = 2.5 / 0.5 = 5
So the perimeter of the hexagon is 6*5 = 30 inches
It’s the last one 7 sqrt5+8sqrt2/27
your answer would be c. y times parentheses 5 plus y times a. C. y • (5 + y) • a

Circumference = pi * diameter
diameter = 8.5; pi = 3.14
C = 3.14 * 8.5
C = 26.69 in = 26.7 in
