velikii [3]
7/12.

If you make  1/3, 5/12, and 1/2 the same denominator, it will be:
                     4/12,5/12,and 6/12.

you can see that these fractions are increasing 1/12 for each day. so on the forth day, it will be 7/12.

A searchlight is shaped like a paraboloid of revolution. If the light source is located 2 feet from the base along the axis of s
zhenek [66]

Answer:

3 ft.

Step-by-step explanation:

We have that the parabola formula has the following general equation:

x ^ 2 = 4py

p would come being the distension of the vertex until the focus.

They tell us that this value is 3, that is to say p = 3. Replacing we have:

x ^ 2 = 4 * 3 * y

x ^ 2 = 12 * y

reorganizing for and, we are left with:

y = (1/12) * x ^ 2

We know that the opening is 12 feet wide, therefore, the parabola, being symmetry, must be distributed in the same way, in two equal parts, that is, 12/2 = 6. Therefore, being vertical on the x axis must take values of (-6, y), (6, y).

Which means that the value of x is 6 or -6. (it doesn't matter which of the two is when it is squared)

Replacing in the equation obtained:

y = (1/12) * (6 ^ 2)

y = 3

Therefore the depth is equal to 3 ft.

Mr. Design is covering rectangular pieces of plywood with fabric to create a wall hanging. Each piece has an area of 12 3/4 squa
PtichkaEL [24]

Assuming that "piece" refers to the plywood, not the fabric. Very poorly stated
question. Rectangle 1:12 3/4 square inches = 12.75 sq in; 2 1/8 in = 2.125 in;
12.75 sq in / 2.125 in = 6 in.
 Rectangle 2: 2 1/10 in = 2.1 in; 12.75 sq in / 2.1 in = 6.07143..., rounded to 6.1 in; OR 12 3/4 sq in = 51/4 sq in; 2 1/10 in = 21/10 in; 51/4 sq in / 21/10 in = 51/4 * 10/21 = 510/54 in = 85/14 in.
