Danielle Walked From Her House To Several Locations In Her Town. The Graph Represents Her Distance From

Answers

Answer 1

Answer:

The answer for A. Would be 1 mile B. 2mph C. 4mph and the rest Im still working on

Step-by-step explanation:

a. How far from home was Danielle after 1/2 hour?

According to the graph, after half hour, Danielle was 1 mile far from home.

b. What was Danielle's speed between 0 and 1 hour?

To find the speed we have to apply the formula:

From  and , Danielle went from  to  . Replacing this values, we calculate the speed:

Therefore, the speed between 0 and 1 hour is 2 miles per hour.

c. What was Danielle's speed between 1 and 2 hours?

The Danielle's speed between 1 and 2 hours is zero (). Because, according to the graph, during this time, Danielle didn't move, and without move, there's no speed.

d. What is the domain when the function is increasing?

The domain when the function is increasing refers to the increasing x intervals.

From the graph, this increasing interval is from 0 to 1 hours only, it's the only period of time when Danielle was increasing her position.

e. What is the domain when the function is decreasing?

The parts of the decreasing domain are:

From 2 to 3 hours.

From 3 and a half to 4 hours.

In the graph, you can see these decreasing intervals, which are characterized by a downwards direction of the line.

f. What is the domain when the function is constant?

The parts where the function is constant:

From 1 to 2 hours.

From 3 to 3 and a half hours.

Constant intervals, means no increase, no decrease, just an horizontal line.

Which of the following formulas could be used to determine the volume of a cone stacked on top of half a sphere?
Select all that apply.

V = lwh
V = Bh
V = 1/3 Bh
V = pi* r^2h
V = 1/3 pi* r^2h
V = 4/3 pi* r^3

Answers

Answer:

I think it is V=pi* r^2h and V = 4/3 pi* r^3 but I am not 100% sure.

Step-by-step explanation:

The correct options are 5 (1/3 pi* r^2h) and 6 (4/3 pi* r^3).

What is Volume?

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere. Many forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry.

As per the given data:

The formula for volume of various figure is given.

We have to find the formulas which can be used to determine the volume of a cone stacked on top of half a sphere.

Volume of a cone stacked on top of half a sphere:

= Volume of a hemisphere + Volume of a cone

= (Volume of a sphere/2) + Volume of a cone

Volume of a sphere = 4/3 pi* r^3

Volume of a cone = V = 1/3 pi* r^2h

Hence, the correct options are 5 (1/3 pi* r^2h) and 6 (4/3 pi* r^3).

A plant has to grow close to the ground to resist cold and has shallow roots because the soil under it is frozen. In which biome is this plant most likely found? temperate rain forest tundra desert tropical rain forest

Answers

Answer:

tundra

Step-by-step explanation:

The plant that you have described, which has to grow close to the ground and has shallow roots because the soil under it is frozen, is most likely found in the tundra biome. Option B is correct.

What are tundra biomes?

Long, cold winters and short, cool summers characterize the tundra biome.

Here,

Because the soil beneath it is frozen, the plant you described must grow close to the ground and has shallow roots. It is most likely found in the tundra biome.

Long, cold winters and short, cool summers characterize the tundra biome. The soil in the tundra is usually frozen all year, making it difficult for plants to develop deep root systems. As a result, to withstand cold, windy conditions, many tundra plants have shallow roots and grow close to the ground. Lichens, mosses, grasses, and dwarf shrubs are examples of tundra plants.

The ordered pair (−4, 0) is a solution to the first equation because it makes the first equation true.

The ordered pair (−4, 0) is a solution to the second equation because it makes the second equation true.

The ordered pair (−4, 0) is a solution to the system because it makes both equations true.

The ordered pair (−4, 0) is not a solution to the system because it makes at least one of the equations false.

6 photos more if you use the fast printer

30 photos

Step-by-step explanation:

To figure out the answer, it will be much easier to figure out how many pages each printer can print in 1 minute. For the office printer, we need to divide both numbers by 12.5. This means that the office printer can print 2 pages per minute.

Do the same thing for the home printer. We need to divide both numbers by 6. This means that the home printer can print 2.5 pages per minute.

The home printer is indeed faster.

Now, we need to figure out how many more pages can the home printer print in 12 minutes. In 12 minutes, the office printer can print 24 pages. In 12 minutes, the home printer can print 30 pages. The difference in the number of pages between the faster printer and the slower one within 12 minutes is 6 pages.
