Step-by-step explanation:
<u>Given the following data;</u>
Length = 312 meters
Breadth = 186 meters
To find the perimeter of the rectangle;
Mathematically, the perimeter of a rectangle is given by the formula;
Perimeter = 2(L + W)
Perimeter = 2(312 + 186)
Perimeter = 2(498)
Perimeter = 996 meters
To the nearest meters, we have;
Perimeter = 996 ≈ 1000 meters
Let P represent the perimeter of a rectangular field.
900 < P > 1000
Therefore,
Answer:
y = 9x - 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, - 38) and (x₂, y₂ ) = (8, 61)
m = =
= 9, thus
y = 9x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 61), then
61 = 72 + c ⇒ c = 61 - 72 = - 11
y = 9x - 11 ← equation of lie
