Use the graph to write a linear function that relates y to x.

A line graphed on a coordinate plane. The line passes through the points at ordered pair negative 2 commas 0 and ordered pair 0 comma negative 1.

Answers

Answer: y = -0.5*x - 1

Step-by-step explanation:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Here we know that we have a line that passes through the points (-2, 0) and (0, -1)

Then the slope for this line is:

a = (-1 -0)/(0 - (-2)) = -1/2 = -0.5

Then our line is something like:

y = -0.5*x + b

now we know that this line passes trough the point (0, -1), this means that when x = 0, y must be equal to -1

Then we can replace these values in the equation in order to find the value of b.

-1 = -0.5*0 + b

-1 = b

Then the equation is:

y = -0.5*x - 1

The side of a hill makes a 12° with the horizontal. A wire is to be run from the top of a 175 foot tower on the top of the hill to a stake 120 ft down the hillside from the base of the tower. What length of wire is needed

Answers

Answer:

231.9ft

Step-by-step explanation:

We would be solving this problem by using the cosine rule.

The length = (pq)² + (qr)² -2 * pq * qr * cos102⁰

= 120² + 175² - 2*120*175 (-0.2079)

= 14400 + 30625 + 8731.8

= 53756.8

Length² = 53756.8

We take the square root of both sides

Length = √53756.8

Length = 231.89 feet

This is the length of the wire that is needed.

Thank you

The volume of this cylinder is 175pi cubic units. What is the volume of a cone that has the same base area and the same height? Write your answer in terms of pi.

Answers

Answer: 58.33π units ³

Step-by-step explanation:

The volume of a cylinder = πr²h

The volume of a cone = 1/3πr²h

Since we have been told that the volume of this cylinder is 175pi cubic units and that the cone has the same base area and the same height, then the volume of the cone will be the volume of the cylinder divided by 3. This will be:

= 175π / 3

= 175/3π

= 58.33π units ³

The volume of the cone is 58.33π units ³

Answer:

183

Step-by-step explanation:

When multiplied by pi, it rounds out to 183.

a book has a hundred and twenty. I have read a quarter of the pages. How many pages do I have?

Answers

Answer:

You have 90 pages left.

Step-by-step explanation:

1/4 × 120 = 30 pages read

Therefore

120- 30

=90 pages left to read

Answer:

You read 30 pages of the book.

You have 90 pages left.

Step-by-step explanation:

120 total pages

⇒ 120 = 100%

[tex]\frac{1}{4}[/tex] pages have been read

⇒ [tex]\frac{1}{4}[/tex] = 25%

[tex]\frac{3}{4}[/tex] remaining

⇒ [tex]\frac{3}{4}[/tex] = 75%

120 x .25 = 30 pages read

120 x .75 = 90 pages unread

30 + 90 = 120

simplify to the lowest terms

What is the área of this figure? (I need the answer bc this Is due in 1 hr )

Answers

Answer: 353ft

Step-by-step explanation:

To work out what the area of this composite shape is, you would split it into two shapes; a square and a rectangle.

For the formula of the rectangle and square you would do base x height.

So,

For the square you do 13x13=169

For the rectangle you would do 23x8=184

Then to work out the total area of the two shapes you would add the two areas together.

169+184=353
