You are the head of a building department . Your department is making final inspections of two types of new commercial buildings

--gas stations and restaurants . Final inspections involve the work of three separate inspectors : a plumbing inspector , an electrical inspector , and a building inspector . The plumbing inspector requires 4 hours to inspect a gas station and 2 hours to inspect a restaurant . The electrical inspector requires 2 hours to inspect a gas station and 6 hours to inspect a restaurant . The building inspector requires 4 hours to inspect a gas station and 6 hours to inspect a restaurant . Considering the time required for other duties , the plumbing inspector has 28 hours a week available for inspections ; the electrical inspector has 30 hours available and the building inspector has 36 hours available . You want to inspect as many commercial buildings as possible each week . Set up this problem as a linear programming problem .​

When you reflect over the y-axis, sign of the ___-coordinate changes.
KATRIN_1 [288]

Answer:

When we reflect over the y-axis, sign of the x-coordinate changes.

Step-by-step explanation:

Since we know when we'll reflect over y-axis, y-axis will work as a mirror. Y-coordinates will remain same but the only change that happens to any point on the graph is x coordinates.

In second quadrant x-coordinates are negative and in first quadrant positive, while y coordinates are positive in both first and second quadrant. So if we will reflect from first to second or second to first quadrant y-coordinates will remain same but x-coordinates will change..

In third quadrant x-coordinates are negative and in fourth positive, while y coordinates are negative in both third and fourth quadrant. So if we will reflect from third to fourth or fourth to third quadrant y-coordinates will remain same but x-coordinates will change.

Therefore, from above explanation we can conclude that when we reflect over the y-axis, sign of the x-coordinate changes.

Find the surface area of a cylinder with a base diameter of 8ft and a height of 6ft. Write your answer in terms of pi, and be su
Ksju [112]

Given that diameter of the base of the cylinder = 8 ft

Given that height of the cylinder = 6 ft

We have to find the surface area of the cylinder in terms of pi.

So we need to use formula of surface area of the cylinder which is

Area= 2\pi r(r+h)

where h= height = 6

r= radius = diameter/2 = 8/2 = 4

Now plug these values into above formula

Area= 2\pi *4(4+3)

Area= 2\pi *4(7)

Area= 2\pi *28

Area= 56\pi

Hence final answer is

Area= 56\pi square ft

What is the height of a triangular prism that has a height of 9 meters and a base with the following deminsions 4m 14m
Andrew [12]

Answer:

252m^3

Step-by-step explanation:

A solid having a triangular base is what we call a triangular prism. For every prism, its volume is always equal to the area of its base times its height. In other words:

V = AxH

V - volume

A- area

H - height of prism

We know that:

h = 4 m (side of base)

b = 14 (other base side)

A = bh/2 = 14x4/2 = 28 m^2

And then: V = A x H = 28 x 9 = 252 m^3

What is the value and is it minimum or max
vova2212 [387]

Answer:

minimum and value of 4

Step-by-step explanation:

\frac{dx}{dy} = 2x-8

When \frac{dx}{dy}=0  we will be able to get the critical points.

2x-8 =0x=4

The graph is a quadratic graph with a 'U' shape, thus it has a minimum critical point.

A tepee has a circle floor with a diameter of 4 yards what’s the floors circumference
Firlakuza [10]

Answer:

12.57 yards

Step-by-step explanation:

The circumference of a circle is denoted by: C=\pi d, where d is the diameter.

Here, we are given the diameter, so d = 4.

Now, plug this into the equation:

C=\pi d

C=\pi *4 ≈ 12.57

The circumference is about 12.57 yards.

Hope this helps!
