Answer:
Surface area = 39 yards²
Step-by-step explanation:
∵ the surface area of the pyramid = 1/2 pl + base area
Where p = perimeter of the base , l = slant height
∵ Area of the base = 3 × 3 = 9 yards²
∵ Perimeter of the base = 4 × 3 = 12 yards
∵ Slant height = 5 yards
∴ The surface area = 1/2 × 12 × 5 + 9 = 39 yards²
Answer:
A. Height is input, Weight is output
Step-by-step explanation:
We are given the statement,
"Weight is a function of height".
As we know,
<em>In a function of the form
, the input variable is 'x' and the output variable is 'y'.</em>
If we write the given statement in the form
, we get,

This means that the input variable is 'Height' and the output variable is 'Weight'.
Hence, option A is correct.
