Answer:
<em>4√5</em>
Step-by-step explanation:
The length of the radius of the circle will be the distance between the two coordinates. Using the formula:
D = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinates (-4‚-2) and (-8‚-10)
R = √(-8-(-4))²+(-10-(-2))²
R = √(-4)²+(-8)²
R = √16+64
R = √80
R = √16*5
R = 4√5
<em>Hence the length of the radius of this circle is 4√5</em>
W= width L= length = 2W
Area of Rectangle= Length * Widthsubstitute the area and the value of L in the formula
28,800 m^2= 2W * W
28,800= 2W^2divide both sides by 2 in an effort to isolate the variable w
14,400= W^2take the square root of both sides
√14,400= W^2
we want the negative and positive root of the radicand (the number under the radical symbol - 14,400 in this case)
120= w OR -120= w
LENGTHL= 2W= 2(120)= 240 meters
ANSWER: The side lengths are W= 120 m; L= 240 m. Even though W= -120 too, it is not a valid solution in this case since a field cannot have a negative value.
Hope this helps! :)
Answer:
slope =( y2 - y1 ) ÷ (x2 - x1)
Step-by-step explanation:
p1 ( -1 , -2)
p2 (4 , 2 )
slope =
135 - 18 = 117 cm
Rita = 117 cm tall
117 cm + 30 = 147 cm
Jan is 147 cm tall.
