Answer:

12.9 square yards

Step-by-step explanation:

The base is an equilateral triangle, so we can assume that the three faces have the same dimensions. Each of those face triangles has an area of ...

A = 1/2bh

A = 1/2(3 yd)(2 yd) = 3 yd²

The base area is computed using the same formula and the given height:

A = 1/2(3 yd)(2.6 yd) = 3.9 yd²

Then the total surface area is that of the base and the three faces:

SA = (3.9 yd²) + 3(3 yd²) = 12.9 yd² . . . total surface area

If (x)=<br> X-2<br> and d(x) = x + 3, what is the domain of (cd)(x)?

Nata [24]

Answer:

Option (2)

Step-by-step explanation:

Given functions are,

c(x) = $\frac{5}{x-2}$

d(x) = x + 3

Equation of the composite function will be,

(cd)(x) = c(x) × d(x)

= $\frac{5}{(x-2)}\times (x+3)$

= $\frac{5(x+3)}{(x-2)}$

This function is defined only when denominator is not equal to zero.

(x - 2) ≠ 2

Therefore, for real numbers except x = 2 will be the domain of the composite function.

Option (2) will be the answer.
