As what I can observe, the pathway can be formed with 2 right triangles. Thus, I'll get the area of the 2 right triangles and multiply its area by the paving cost per square meter.
Area of Right Triangle: ab / 2
a = 6 2/3 m ⇒ 20/3 m; b = 3m
Area of 1 triangle= (20/3 m * 3 m) ÷ 2 = 20 ÷ 2 = 10 m²
Area of 2 triangles = 10m² * 2 = 20 m²
Total cost = $40 * 20m² = $800
Answer:
The equation of the line is y = -1
Step-by-step explanation:
In order to find the equation,y = mx + c, you have to find the gradient first using the formula :
Let (x1,y1) = (-8,-1) & (x2,y2) = (-8,-1),
m = (-1)-(-1)/-8-(-8)
= 0
Now, we have found the gradient, next using the formula, y = mx + c to find the equation :
y = mx + c
Let m=0,
At (-8,-1)
-1 = 0(-8) + c
c = -1
y = -1
Ok so I think I don’t know but I’m gonna guess ccccccccc
