(k+3h)(k-3h) or -9h^2+k^2
Answer:
The correct answer is A) It has rotational symmetry about the origin.
Step-by-step explanation:
In principle, the graph of an odd function is symmetric with respect to the origin. This simply means that the point (0 ,0) acts as a mirror line to the function so that one half of the function looks exactly like the other half when reflected over the origin.
A function f(x) is said to be odd if and only if;
f(-x) = -f(x)
The ultimate example of an odd function is the sine function. Consider the function below;
f(x) = sin(x)
Then;
f(-x) = sin(-x) = -sin(x) = -f(x)
Working with actual values;
sin(-30) = -sin(30) = -0.5
A graph of the function f(x) = sin(x) is shown in the attachment below;
If the graph is rotated about the origin, we would still end up with the same graph.
In summary, an odd function is symmetric with respect to the origin and has rotational symmetry about the origin.
The surface are of the right cone is 176 sq.units. Option A) is the correct answer.
<u>Step-by-step explanation</u>:
<u>step 1</u> :
Radius of the cone, <em>r = 4</em>
Height or length of the cone,<em> h = 10</em>
<u>step 2</u> :
Total surface area of right cone = πrh + πr^2
= (π410) + ( π4^2)
= 40π + 16π
= 56 π = 563.14
= 176 sq.units
