What is the equation for the given graph expressed in the form of y=a|x-h|+k?

Step-by-step explanation:

Consider the parent function (The graph of this function is represented by green curve in attached diagram)

1. Stretch this function by a factor of 5. The function represents this stretched function and the graph of this function is blue graph in attached diagram.

2. Translate the graph of the function 5 units down and get the function (red graph in attached diagram). This is exactly the graph of the function shown in the task, so

answer: 60

step-by-step explanation:

1/2a + (2/3×30)   = 50

1/2a + 20 = 50

1/2a = 30

a = 60

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
