Answer:
The equation of the graph after translating one unit to the left is;
Step-by-step explanation:
The given equation is
We note that minimum value of y = 3, where 1/2·x - 2 = 0 and x = 4
Therefore, in moving one unit to the left, we have at the y-intercept where slope of the graph has become inverted (reflection of the real graph) we add one to the x value as follows;
The equation of the graph becomes;
.
Given:
Diameter of the hole = 30 cm
To find:
The area of the hole.
Solution:
The radius of a circle is always half of the diameter. It is given that the diameter of the hole is 30 cm. So, the radius of the hole is:
Area of a circle is:
Putting and
in the above formula, we get
Therefore, the area of the hold is 706.5 square cm.
