Answer:
Step-by-step explanation:
Assuming a perpendicular line(apotherm) is extended from the midpoint of the polygon to the midpoint of one of its sides, then we can determine the length of the apotherm by applying Pythagorean theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Let a represent the apotherm
Hypotenuse = 4
Apotherm = a
Opposite = a(apotherm = length of each side/2)
Therefore,
4² = a² + a²
16 = 2a²
a² = 16/2 = 8
a = √8 = 2√2
The formula for determining the area of a polygon is expressed as
Area = a² × n × tan 180/n
Where n represents the number of sides of the polygon.
n = 6
Therefore,
Area = (2√2)² × 6 × tan(180/6)
Area = 48 × tan 30
Area = 27.2
Answer:
The equation is y = -5x + 55
Slope = -5
y-intercept = 55
Step-by-step explanation:
The given table shows the different coordinates of points on a straight line.
The general equation of a line is y = mx + b
where m is the slope and b is the y intercept.
Actually , here only 2 values are needed but there are 4 values given which is just to check whether our line is correct or not.
Substitute values of x and y in the equation.
Put (1,50),
50 = m + b ----------(1)
Put (2,45),
45 = 2m + b -----------(2)
Solve (1) and (2),
Slope , m = -5
y-intercept , b = 55
Hence , the equation is y = -5x + 55.
Please, use " ^ " to denote exponentiation: x^2 + 4x - 21 = 0
Factor: (x+7)(x-3)=0
Solve for the 2 roots: x= -7 and x= 3: {3, -7} Note how this is in set notation.
