Answer:

$132\pi$

Step-by-step explanation:

The lateral area is the area of a rectangle. Think of a soup can with the label removed and laid out flat on a table. The height of the rectangle is the same as the height of the can (cylinder). Where does the base of the rectangle come from? It's the circumference of the can "unrolled."

Area of a rectangle = base x height

Circumference of a circle $C=2\pi r$

Lateral Area $=2\pi r \times h$ $=2 \pi (6)(11) =132\pi$

A plane can travel 5000 kilometers<br> in 6 hours. How far can it travel in<br> 1.5 hours?

kompoz [17]

Answer:

1250 Kilometers.

Step-by-step explanation:

Start by finding the proper ratio of 5000:6. Now divide 6/1.5 to see what we need to divide 5000 by. 6/1.5 is 4. So divide 5000 by 4. This gives you an answer of 1250 kilometers.

Which function is graphed below?<br> y=j3)

natita [175]

Answer:

$y = 3(\frac{1}{3} )^{x}$

Step-by-step explanation:

See the attached graph.

The points (0,3) and (1,1) are on the graph of the exponential function.

Let the function be $y = a(b)^{x}$ ....... (1)

Now, satisfying the point (0,3) we get from the equation (1),

$3 = a(b)^{0} = a$

Therefore, the initial value of the function is a = 3

Hence, the equation becomes $y = 3(b)^{x}$ ......... (2)

Now, satisfying the point (1,1) we get from equation (2)

$1 = 3 (b)^{1}$

⇒ b = 1/3

So, the final equation becomes $y = 3(\frac{1}{3} )^{x}$ (Answer)

The azalea is located at point (4, -4). You have already plotted the hydrangea at (4, 6). If you count up the number of squares from the hydrangea to the azalea plant, you will get a distance of 10.

Since the problem tells you the length of each square is 1 ft, then you know that the distance between the two plants is 10 squares * 1 ft/square = 10ft.
