The linear function on a coordinate plane passes through (-5, -3) and (0, -4) is y = -1/5x-4

Linear function are functions that has a leading degree of 1. The equation of a linear function is expressed as y = mx + b

where

m is the slope

b is the intercept

Given the coordinates (-5, -3) and (0, -4)

Slope = -4+3/0+5
Slope = -1/5

The y-intercept of the line will be -4

Determine the equation

y = -1/5x-4

Hence the linear function on a coordinate plane passes through (-5, -3) and (0, -4) is y = -1/5x-4

Answer: 113.1 ft^3

Step-by-step explanation:

We know the radius is 3 so substitute it in the formula like this...

V = 4/3 π (3)^3

Solve for (3)^3 which is 27.

Next multiply 4/3 by π. Which equals 4.1887....

Then multiply that answer by 27.

And your answer is 113.1 ft^3.

Answer:

[tex]V=108ft^{3}[/tex]

Step-by-step explanation:

[tex]V=\frac{4}{3}(3)(3)^{3}[/tex]

Answer:

y = 3x - 7

Step-by-step explanation:

Since the lines are parallel, the slopes will be the same.  In this case 3.  Now we have to find the y-intercept.  We will use the slope (3), the x (2) and  y (-1) to help us do this.  We get the x and the y from the ordered pair given(2,-1).

y = mx + b

-1 = 3(2) + b   Plug in what you know

-1 = 6 + b       Subtract 6 from both sides

-7 = b

Now we can write the equation

y = 3x -7

The given analytical tools:

a. The single sample z-test analysis is appropriate for the data where the sample size is large and all data points are independent. Where the standard deviation is given(known).

b. The single sample t-test analysis is appropriate for the data where the sample size is small and the population variation or standard deviation is unknown.

This is a type of hypothesis test where the sample means and the population means are compared when the population variance or the standard deviation are given(known).

z = (X - μ)/(σ/√n)

Where X - sample mean, μ - population mean, σ - population standard deviation, and n - sample size.

Here the sample size is large and all data points are independent.

This is a type of parametric hypothesis test where the sample means and the population means are compared when the population variance or the standard deviation are not given(unknown).

The following system of equation can be solved by first substituting the dependent variable in the other equation . The solution yields x = -1.5 and y = 6.5 .

The two equations are given as -

4x-2y=7

3x-3y=15

First substituting the value of x from the first equation and then putting that value in the second equation for the following system of equation.

From first equation,

⇒ 4x = 7 + 2y

∴  x = (7 + 2y)/4

Putting this value of x in second equation,

⇒ 3*(7 + 2y)/4 - 3y = 15

⇒ 3*(7 + 2y) - 12y = 60

⇒ 21 + 6y - 12y = 60

⇒ -6y = 39

∴  y = -6.5

∴ x = (7 + 2y)/4 = -1.5

Thus x = -1.5 and y = -6.5

Therefore, the following system of equation can be solved by first substituting the dependent variable in the other equation . The solution yields x = -1.5 and y = 6.5 .

y = 4 is the equation of the line that represents Saturn Avenue given that Christopher decides that another road to be named Saturn Avenue is needed that will go past the cleaners and be perpendicular to Planet Drive. This can be obtained by using the formula for finding the equation of the line.

Equation of a line can be determined using the formula,

y = mx + c

where m is the slope of the line and c is the y - intercept.

m = rise/run = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)

Here in this question draw the line passing through cleaners and perpendicular to Planet Drive.

The point where x = 0 is (0, 4)

This means that y - intercept is 4

By considering two points on the line we can find the slope of the equation,

Consider the points (8, 4) and (16, 4)

m = rise/run = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)

m = (4 - 4)/(16 - 8) = 0/8 = 0

So we got that,

Putting in the equation of line we get,

y = mx + c

⇒ y = (0)x + 4 ⇒ y = 4

Hence y = 4 is the equation of the line that represents Saturn Avenue given that Christopher decides that another road to be named Saturn Avenue is needed that will go past the cleaners and be perpendicular to Planet Drive.

The jo's drink have stronger pineapple taste.

Given that fruit punch calls for 333 liters of orange juice and 222 liters of pineapple juice and Jo creates a drink by mixing 444 liters of orange juice with 333 liters of pineapple juice.

In the Recipe for fruit punch calls

The Number of liters of orange juice = 333.

The Number of liters of pineapple juice = 222.

Thus, Total number of liters of juice = 222+333= 555 liters

Now, % of pineapple juice in fruit punch is

P₁=(222/555)×100

P₁=0.4×100

P₁=40%

Further, % of orange juice in fruit punch is

O₁=(333/555)×100

O₁=0.6×100

O₁=60%

In Jo's drink

The Number of liters of orange juice = 444.

The Number of liters of pineapple juice = 333.

Thus, Total number of liters of juice = 444+333= 777 liters

Now, % of pineapple juice in jo's drink is

P₂=(333/777)×100

P₂=0.43×100

P₂=43%

Further, % of orange juice in jo's drink is

O₂=(444/777)×100

O₂=0.57×100

O₂=57%

Hence, the taste of both drinks was not the same, jo's drink will have a stronger pineapple taste and jo's drink will have a lesser orange taste.
