Answer:
38 ft²
Step-by-step explanation:
We need to find the green area.
The hole has the shape of a polynomial made up of a rectangle and a triangle. The rectangle has length 8 ft and width 3 ft. The triangle has base 7 ft and height 4 ft.
area of rectangle = length * width
area of triangle = base * height / 2
The total area is the sum of the areas of the rectangle and the triangle.
area = area of rectangle + area of triangle
area = LW + bh/2
area = 8 ft * 3 ft + 7 ft * 4 ft/2
area = 24 ft² + 28 ft²/2
area = 24 ft² + 14 ft²
area = 38 ft²
Hope this Helps :)
Answer:
Step-by-step explanation:
The first one is actually 0 I think. The instantaneous ROC at x=1 should also be 0. The last one should be correct.
Basically, the ROC for the first one is 0 because the y value at the start and end of the interval is the same, so the change is the same. However, for the instantaneous ROC at x = 0, you look at the graph and realize that if you find the derivative at that point, it is 0.
