Answer:
Area = 50.24 feet^2
Step-by-step explanation:
radius = 4 feet
Area =?
Substitute values into the given equation
--------------------------------------------------
Find Slope
--------------------------------------------------
y = -1/3 x + 4
Slope = -1/3
Slope of the parallel line = -1/3
--------------------------------------------------
Insert slope into y = mx + c
--------------------------------------------------
y = -1/3 x + c
--------------------------------------------------
Find y-intercept
--------------------------------------------------
y = -1/3 x + c
at point (6, 5)
5 = -1/3 (6) + c
5 = - 2 + c
c = 5 + 2
c = 7
--------------------------------------------------
Insert y-intercept into y = -1/3x + c
--------------------------------------------------
y = -1/3 x + 7
--------------------------------------------------
Answer: y = -1/3 x + 7 (Answer B)
--------------------------------------------------
Answer: length = 7 feet's
Width = 6 feets
Step-by-step explanation:
Perimeter of a rectangle is the distance round the rectangle.
Perimeter of rectangle is expressed as
2(length + width)
The perimeter of the given rectangle is 26 feet. Therefore
2(L + W) = 26
Dividing by 2,
L+W = 13
The area of a rectangle is expressed as length × width
The given area is 42 square feet. Therefore,
L×W = 42
Substituting L = 13 - W into LW = 42, it becomes
W(13-W) = 42
13W - W^2 = 42
W^2 -13W + 42 = 0
W^2 -7W - 6W + 42 = 0
W(W - 7) - 6(W - 7) = 0
(W-6)(w-7)=0
W-6 = 0 or W-7=0
W=6 or W = 7
L= 13-6 or L= 13-7
L= 7 or L = 6
