Answer:

y = -4/5x - 5

Step-by-step explanation:

4x + 5y = 45

we need to write it in slope intercept form, so:

5y = -4x + 45

y = -4/5x + 45/5

y = -4/5x + 9

The line is parallel so the slope will be -4/5x, point ( -5 -1 )

y = mx + b

-1 = -4/5(-5)+b

-1 = 4 + b

-1 - 4 = b

-5 = b

y = -4/5x - 5

Show a graph Slope function of -1 with a y intercept of 3

castortr0y [4]

Answer:

<h2>In the attachment.</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

We have m = -1 and b = 3. Substitute:

$y=-1x+b\to y=-x+3$

The graph is a straight line. Therefore we need only two points to plotting the graph.

One we have, the y-intercept (0, 3). Calculate other point.

Put any value of x to the equation of a line and calculate the value of y:

For x = 3:

$y=-3+3=0\to(3,\ 0)$

The volume of a right circular cone that has a height of 13 m and a base with a diameter of 3.4 m. Round your answer to the near

Mamont248 [21]

Answer:

The volume of right circular cone having height = $13 \ m$ and Diameter = $3.4 \ m$ is $39.4\ cubic\ meter$ .

Step-by-step explanation:

Diagram of the given scenario is shown below.

Given that

Height of a right circular cone is $13 \ m$ .

Diameter of the right circular cone is $3.4 \ m$ .

To find: The volume of a right circular cone.

So, From the question,

$Height = \ 13 \ m\\diameter = 3.4\ m$

$Radius = \frac{diameter}{2}= \frac{3.4}{2}$

⇒ $Radius = 1.7\ m$

Now

Volume of right circular cone = $\frac{1}{3}\pi r^{2}h$

$=\frac{1}{3}\times\frac{22}{7} \times (1.7)^{2}\times 13$

= $\frac{826.54}{21}$

$= 39.4\ cubic\ meter$ .

Therefore,

The volume of right circular cone having height = $13 \ m$ and Diameter = $3.4 \ m$ is $39.4\ cubic\ meter$ .

Ash company reported sales of $580,000 for year 1, $630,000 for year 2, and $680,000 for year 3. Using year 1 as the base year,

Elenna [48]

Answer:

Year 2: 109.4%

Year 3: 118.9%

Step-by-step explanation:

<h3>Given;</h3>

Ash company reported sales of $580,000 for year 1
$630,000 for year 2,
$680,000 for year 3.

Now,

For the revenue trend percent for year 2

Year 2: $580,000 / $530,000 × 100 = 109.4%

For the revenue trend percent for year 3

Year 3: $630,000 / $530,000 × 100 = 118.9%

Thus, The answer is 109.4% and 118.9%.
