Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13
Answer:
28.27m
Step-by-step explanation:
the formula for area of a circle is
A= π x r^2
A = π x r^2 = π x 3^2 = 28.27433
Given the data below, the total length or amount of decorative trim can be calculated. It can be said that the total length of decorative trim is equal to the total perimeter of the two walls, the window, and the door, minus the base of the door.
Wall 1 = 2(8) + 2(18) = 52 ft.
Wall 2 = 2(8) + 2(15) = 46 ft.
Window = 2(3) + 2(6) = 18 ft.
Door = 2(7) + 5 = 19 ft.
Total length = 52+46+18+19 = 135 ft. of decorative trim
