Answer 1

Answer:

An equation for the parabola would be y²=-19x.

Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form

(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.

Beginning with the directrix:

x=h-p=4.75

h-p=4.75

Since the vertex is at (0, 0), this means h=0 and k=0:

0-p=4.75

-p=4.75

p=-4.75

Substituting this into the standard form as well as our values for h and k we have:

(y-0)²=4(-4.75)(x-0)

y²=-19x

Maurice and his father are building a dog house. They are using long pieces of wood and cutting them into smaller pieces. They have a piece of wood that is 3.6 feet long and are cutting it into pieces that are each 0.75 feet. How many smaller pieces will they be able to make?

Answers

Answer:

4.8 smaller pieces

Step-by-step explanation:

Total length of wood = 3.6 feet

Length of each piece = 0.75 feet

How many smaller pieces will they be able to make?

Number of smaller pieces of wood = Total length of wood / Length of each piece

= 3.6 feet / 0.75 feet

= 4.8 smaller pieces

Number of smaller pieces of wood = 4.8

Answers

Answer:

25/3

Step-by-step explanation:

Set the equations equal to each other since the lines are parallel.

(x+20)=(4x-5)

-x +5 -x +5

25/3 = 3x/3

x = 25/3

Since these equations are consecutive interior angles, they will add up to 180.
The equation will be (x+20)°+(4x-5)°=180.

(x+20)+(4x-5)=180
5x+15=180
5x=165
165/5x
=33°

You can make sure your answer is correct by putting your x back into the equation.
(33+20)+(4•33-5)
53+132-5
53+127
180

Assignment Summary For this assignment, you will construct a scientific model of the water cycle to show how water is recycled through an ecosystem. Once you have drawn your model on a poster board, you will write one to two paragraphs explaining how water is transferred within and between organisms and the environment. Background Information Water is a very important compound. Organisms need water to carry out life-maintaining processes such as growth and development. Without water, living things will not survive. Water continually flows among the atmosphere, land, water, and living organisms. This process, called the water cycle, allows water to be recycled as it moves through Earths spheres. Materials Assignment Instructions Step 1: For this project, you are expected to submit the following: 1. Your model of the water cycle 2. One to two typewritten paragraphs describing the water cycle Step 2: Prepare for the project. a) Read through the guide before you begin so you know the expectations of this project. Pay particular attention to the instructions you need to follow to create a model on your poster board. b) If anything is not clear to you, be sure to ask your teacher. Step 3: Gather materials for the model. a) Start with a blank poster board. Be sure to put your name on it. b) You may either draw the parts of the water cycle or print images to construct a model on your poster board. Gather any drawing tools that you will need, or print any images you want to use. Step 4: Create a model of the water cycle. a) Your model should include bodies of water such as lakes and oceans, organisms, air, and land. b) Draw arrows indicating how water moves within an ecosystem and between organisms and their environment. Be sure to include the Sun and gravity in your model. c) Include short phrases on your poster that summarize what occurs at each stage of the water cycle Step 5: Write a paragraph describing the water cycle. a) Type one to two paragraphs describing the full water cycle.
