Answer:
3 1/2cm
Step-by-step explanation:
Seventy-two thousand five hundred
The shape is a trapezoid and its area formula is:
A =

h
a is a base length, b is another base length and h is the height.
A =

(10.8)
A = 81
So the area of the shape is 81yd²
Answer:
y = 1(x - 5)² + 3
Step-by-step explanation:
The general formula of a quadratic equation is written as;
y = a(x − h)² + k
Where (h, k) are the x and y coordinates at the vertex.
Our vertex coordinate is (5, 3)
Thus;
y = a(x - 5)² + 3
Now,we are given another coordinate as (8, 12)
Thus;
12 = a(8 - 5)² + 3
12 = 9a + 3
9a = 12 - 3
9a = 9
a = 9/9
a = 1
Thus,the equation is;
y = 1(x - 5)² + 3
