The complete function is: [tex]y = x+55[/tex]

Step-by-step explanation:

the given table represents a linear function

The linear function is represented by:

[tex]y = mx+b[/tex]

Here

m is the slope of function and b is the y-intercept

In this case, m will be calculated as:

[tex]m= \frac{Change\ in\ y}{Change\ in\ x}\\= \frac{61-60}{6-5}\\= 1[/tex]

Hence the slope is 1.

Putting in the equation

[tex]y = x+ b[/tex]

To find the value of b, we will put any pair of x and y in the equation

[tex]61 = 5 + b\\b = 60-5\\b = 55[/tex]

Hence,

The final equation for linear function is:

[tex]y = x + 55[/tex]

Answer:

A

Step-by-step explanation:

The picture below illustrates a hyperbola.

The intersecting plane does not pass through the vertex of a right circular cone (the vertex of the cone is the point where two nappes meet).

As you can see from the diagram, the plane intersects both nappes of a right circular cone.

Hence, correct option is option A: The plane does not pass through the vertex and intersects both nappes of a right circular cone.

Answer:

x=0

y=-3

6x-5y=15

x=y+3

Replace x with y+3

6(y+3)-5y=15

Distribute

6y+18-5y=15

y= -3

x=0

The solution to the system of equations is x = 0 and y = -3.

To solve the system of equations:

1. 6x - 5y = 15

2. x = y + 3

We can substitute equation 2 into equation 1 to find the value of x, and then use that value to find the value of y.

Substituting equation 2 into equation 1:

[tex]\[6(y + 3) - 5y = 15\]\[6y + 18 - 5y = 15\]\[y + 18 = 15\]\[y = 15 - 18\]\[y = -3\]\\[/tex]

Now that we have found y, we can substitute this value back into equation 2 to find x:

[tex]\[x = (-3) + 3\]\[x = 0\][/tex]

So, the solution to the system of equations is x = 0 and y = -3.

Answer: 19 /4 or 4 3/4

Step-by-step explanation:

Turn 67/8 into a improper fraction, which is 55/8

Next, also convert 21/8 into an improper fraction, which is 17/8

Next, subtract 17/8 from 55/8 and you should get 38/8

Last, simplify 38/8 to do so divide 38/8 by 4/4 and you should get 19/4 and if you want it's optional to turn it into a mixed number.  

The estimate of the difference between the two fractions is: 4 3/4 = 4.75 ≈ 5.

To find the difference of two fractions means that subtract one from the other.

Thus:

Difference between 6 7/8 and 2 1/8 = 6 7/8 - 2 1/8

Change the mixed fraction to improper fractions

55/8 - 17/8

= (55 - 170/8

= 38/8 = 19/4

= 4 3/4 = 4.75 ≈ 5.

Therefore, the estimate of the difference between the two fractions is: 4 3/4 = 4.75 ≈ 5.

Answer:

30 players.

Step-by-step explanation:

3 rows of 8 = 3 x 8 = 24. Plus an additional 6 players in the fourth row. 24 + 6 = 30.

The team photo consists of 30 players: 24 in the three full rows, each with 8 players, and 6 more players in the fourth row.

To find the total number of players in the team photo, you can simply add the number of players in each row together. In this case, there are three rows of 8 players each and a fourth row with 6 players.

First, calculate the total number of players in the three full rows, where each row has 8 players:

3 rows x 8 players/row = 24 players

Now, add the players from the fourth row:

24 players (from the full rows) + 6 players (from the fourth row) = 30 players

So, there are 30 players in the team photo.

In summary, the team photo includes 30 players, with 24 players in the three full rows of 8 each and an additional 6 players in the fourth row.

Final answer:

To estimate the remaining advertisement budget, calculate the total possible maximum expense and subtract it from the initial budget, resulting in an approximate remaining amount of $14,300.

Explanation:

Mr. Kellen's starting budget for advertisements was $50,000. If I assume that each of the 7 advertisements costs about the maximum amount which is $5,100, the estimated total cost would be 7 times $5,100, which equals $35,700. So, a reasonable estimate of the amount of money remaining after paying for the advertisements is $50,000 - $35,700 = $14,300.

Step-by-step explanation:

Without the actual data, we cannot definitively decide the correct exponential model for the population of the District of Columbia. The options provided all share the same initial quantity, with different growth factors. To pick one, we would need data on the annual population growth or decline.

The question is asking us to choose an exponential model of the form a ∙ bx that best represents the population of the District of Columbia for years after 2005. As we are not provided actual data on the population growth or decline, we can't definitively choose between the options. In this kind of model, a is the initial quantity (population in the year 2005), and b is the growth factor per the time period (in this case: annually). In all options provided we have the same initial quantity '550,521'. The difference is in the growth factors .993, .990, .992, and .991. Without the actual data, we cannot definitively pick one. However, if the population is declining each year, you'd expect the growth factor to be less than 1. In case if it's growing you'd expect it to be more than 1.

The values are [tex]x=\frac{7}{2}[/tex] and [tex]y=\frac{5}{2}[/tex]

The solution is ([tex]\frac{7}{2}[/tex],[tex]\frac{5}{2}[/tex])

Step-by-step explanation:

Given equations are [tex]5x=7y\hfill (1)[/tex] and

[tex]x+7y=21\hfill (2)[/tex]

To solve the given equations by elimination method:

Equation (1) can be written as  [tex]5x-7y=0\hfill (3)[/tex] and

Now multiply the equation (2) into 5 we get

[tex]5x+35y=105\hfill (4)[/tex]

Subtracting equations (3) and (4) we get

[tex]5x-7y=0[/tex]

[tex]5x+35y=105[/tex]

Answer:

The equation of the line is:  y = x + 4

Step-by-step explanation:

When we are given two points passing through a line, we can find the equation of the line by using two - point form.

Two - point form:    [tex]$ \frac{\textbf{y - y}_\textbf{1}}{\textbf{y}_{\textbf{2}} \textbf{-} \textbf{y}_{\textbf{1}}} = \frac{{\textbf{x - x}_\textbf{1}}}{\textbf{x}_{\textbf{2}} \textbf{-} \textbf{x}_{\textbf{1}} }$[/tex]

where [tex]$ (x_1, y_1) \hspace{3mm} \& \hspace{3mm} (x_2, y_2) $[/tex] are the points passing through the line.

Here, let us take two points (can be any two):

[tex]$(x _1, y_1) = (1, 5) $[/tex] and

[tex]$ (x_2, y_2) = (5, 9) $[/tex]

Therefore, we have:

[tex]$ \frac{y - 5}{9 - 5} = \frac{x - 1}{5 - 1} $[/tex]

[tex]$ \iff \frac{y - 5}{4} = \frac{x - 1}{4} $[/tex]

[tex]$ \iff y - 5 = x - 1 $[/tex]

[tex]$ \implies y = x - 1 + 5 $[/tex]

[tex]$ \implies y = \textbf{x + 4} $[/tex] which is the required answer.

Answer:

[tex]v=\frac{0,25}{\pi } ft/min[/tex]

Step-by-step explanation:

There is a relation with the initial and final dimensions of the hopper according to the sand level when its high is 6 feet as follows:

[tex]\frac{h_{1} }{h_{2} }=\frac{r_{1} }{r_2}\\{r_2}=\frac{12ft*6ft}{18ft}\\ r_2=4ft[/tex]

Where the calculated [tex]r_{2}[/tex] is given with the 6 feet hgh.

Then we have the sand flow formula which is:

[tex]Q=A*v[/tex]

Where A represents the area of the transversal section and v  the velocity that we need to know, the area is:

[tex]A=\pi r^{2}\\ A=\pi *4^{2}\\ A=16\pi ft^{2}[/tex]

And finally the sand is dropping when the level is 6 feet high with the velocity (v) :

[tex]v=\frac{Q}{A} \\v=\frac{4}{16\pi }[/tex]

[tex]v=\frac{0.25}{\pi } ft/min[/tex]

The sand level in the hopper is dropping at a rate of approximately 0.08 feet per minute when the sand level is 6 feet high. This is calculated using related rates and the volume formula for a cone. The relationship between radius and height, derivative calculations, and the given sand emptying rate are essential for this solution.

To determine how fast the level of sand is dropping in the hopper, we need to use related rates. The volume V of the sand in the inverted cone is given by the formula:

V = (1/3)πr2h

In this case, the radius r and height h of the sand level are proportional because the shape is a cone. We can express the radius r in terms of the height h using similar triangles. Given the overall height is 18 feet and the radius is 12 feet, we have:

r = (12/18)h or r = (2/3)h

Substituting r into the volume formula:

V = (1/3)π[(2/3)h]2h = (4/27)πh3

We need the rate of change of the height (dh/dt) when h = 6 feet. Given dV/dt = -4 ft³/min (negative because the volume is decreasing), we use the chain rule for differentiation:

dV/dt = (dV/dh)(dh/dt)

First, find dV/dh:

dV/dh = d/dh [(4/27)πh3] = (4/27)π × 3h2 = (4/9)πh2

Using dV/dt = -4 ft³/min:

-4 = (4/9)π(h2)(dh/dt)

When h = 6 feet:

-4 = (4/9)π(62)(dh/dt)

-4 = (4/9)π(36)(dh/dt) = 16π(dh/dt)

Therefore:

dh/dt = -4/16π = -1/4π

dh/dt = -0.08 feet/min

So, the level of sand is dropping at a rate of approximately 0.08 feet per minute when the sand level is 6 feet high.
