The best way to approach this problem is to look at the graph of the given function. Replace values of x from 1 to 24 to indicate the numbers of hours in a day. As seen on the graph, there is only one point where the port is at high tide. That would be at 1:00 am.

Looking at the graph, it would be safe for the boats to be in the port when the graph levels off at around 10 to 24. That's from 10 am to before 12 midnight. Then, they would have to stay away between 12 midnight to before 10 am.

A trapezoid has an area of 30m^2. if all of its side lengths are tripled, what will its new area be

Norma-Jean [14]

Answer:

270

Step-by-step explanation:

Because we do not know what the side lengths are, as long as they multiply to 30m^2, it's fine

For this question, let's just say the base is 5, and the height is 6. If we triple 5, we get 15, and if we triple 6, we get 18. 15*18=270

Now what if, the sides are not 5 and 6. Will the area still be the same? Let's find out.

10*3=30 so we can say for this answer, the base is 3, and the height is 10.

10 tripled is 30, and 3 tripled is 9. 30*9=270

So as we look at these 2 answers. we can conclude that the new area, no matter the side lengths, will be 270

Hope this helpes!

Answer:

23.025 square inches.

Step-by-step explanation:

To do this, we can split our polygon into 3 different shapes, a triangle, and 2 rectangles, and adding the areas of those 3 shapes together.

Specifically, triangle ABC, rectangle ACHI, and rectangle DEFG.

First we can start with the area of the triangle.

The area of a triangle is 1/2b*h. (1/2*base*height)

The base of the triangle AC, which is 4.2 inches. (9-4.8, Total length-DE)

The height is 2.75 inches. (6-3.25, Total height-AI)

Put it into the formual:

1/2*4.2*2.75=5.775

Next, I'm going to find the area of rectangle ACHI. The formula for the is just l*w (length*width)

The length is IH which is 4.2 inches. (9-4.8, total length-DE)

The width is AI which is 3.25 inches. (1.3+0.75+1.2, CD+EF+GH)

3.25*4.2=13.65

Now, we are going to find the area of rectange DEFG. Again, the formula is just l*w.

The length is DE which is 4.8 inches.

The width is EF which is 0.75 inches.

4.8*0.75=3.6

Now we add these areas together.

5.775+13.65+3.6=23.025

So the area of the model is 23.025 square inches.

Evaluate x^1-x^-1+x^0 for x=2

Feliz [49]

Let p (x) = x^1 - x^-1 +x^0
p (2) = 2 -1/2 +1
=( 4 -1+2)/2
= 5/2

Solve the system of equations. (1 point)

DiKsa [7]

Answer: A. (4,1)

Step-by-step explanation:

2x -5y = 3

x -3y = 1

Change the equation to isolate a variable so you can substitute it in the other one.

x = 1+3y so

2(1+3y) -5y = 3

2 + 6y -5y =3

2 + y = 3

y=1

Back to the easy equation we isolated

x = 1+3(1)

x= 4

(4,1) is a point where x=4 and y=1
