Radius of flower bed (r) = 4 ft
\pi = 3.14

Area of flower bed (A) = \pir² = 3.14 x 4² = 50.24 ft²

An art exhibit is made by stacking three identical prisms on top of each other end-to-end so their smallest faces overlap. One o
cestrela7 [59]

The surface area of the exhibit is 1,638 cubic inches.

Step-by-step explanation:

Step 1:

If three prisms are out on top of each other we get a shape as follows;

The length of the base = 9 inches,

The width of the base =6 inches, and

The height of the exhibit = 3(17) = 51 inches.

To find the surface area of the total exhibit we consider there to be only one shape which the above dimension.

Step 2:

There are 6 faces to the exhibit.

The surface area of a rectangular prism is given by;

A=2(w l+h l+h w)

By substituting the values, we get

A=2((6)(9)+(51) (9)+(51) (6)) = 2 (819) = 1,638.

The surface area of the exhibit is 1,638 cubic inches.

Answer:

Answer B:  min. value at -6

Step-by-step explanation:

Complete the square of f(x) = x^2 - 2x - 5.

Note:  Please use " ^ " to denote exponentiation, as shown.

Start with f(x) = x^2 - 2x - 5.

Identify the coefficient of the x term:  it is 2.

Take half of that and square your result:  (1/2)(2) = 1, and then 1^2 = 1.

Add and subtract this 1 between the 2x term and the constant term:

f(x) = x^2 - 2x    + 1   - 1  - 5

Rewrite x^2 - 2x + 1 as a perfect square:

f(x) = (x - 1)^2 - 1 - 5, or    f(x) = (x - 1)^2 - 6

Compare this to the standard form

                                        f(x) = (x - h)^2 + k

We see that h = 1 and k = -6.

The vertex is located at (h, k); here, it's located at (1, -6).

Thus, the minimum value of this function is at the vertex (1, -6).

This agrees with Answer B:  min. value at -6.
