Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

The gradient of this graph is 2/3 so the equation of the line is

[tex]y= \frac{2}{3}x[/tex]

However, the question is asking for proportionality which has the equation:

[tex]y=kx[/tex]

So k in this instance is [tex]\frac{2}{3}[/tex].

Answer: The answer is 50 m³.

Step-by-step explanation: We are given to find the volume of the cone cone after being dilated by a factor of one-third from a cone with volume  1350 m³.

The volume of a cone with base radius 'r' units and height 'h' units is given by

[tex]V=\frac{1}{3}\pi r^2h.[/tex]

Therefore, if 'r' is the radius of the base of original cone and 'h' is the height, then we can write

[tex]V=\frac{1}{3}\pi r^2h=1350[/tex]

⇒ [tex]\pi r^2h=4050.[/tex]

Now, if we dilate the cone by a scale factor of , then the radius and height will become one-third of the original one.

Therefore, the volume of the dilated cone will be

[tex]V_d=\frac{1}{3}\pi (\frac{r}{3})^2\frac{h}{3} =\frac{1}{81}[/tex] × [tex]\pi r^2h=\frac{1}{81}[/tex] × [tex]4050=50[/tex]

Thus, the volume of the resulting cone will be 50 m³.

Answer:

[tex]x=2,-3[/tex]

Step-by-step explanation:

Set [tex](x-2)(x+3)^2[/tex] equal to [tex]0[/tex].

[tex](x-2)(x-3)^22=0[/tex]

Solve for [tex]x[/tex].

If any individual factor on the left side of the equation is equal to [tex]0[/tex], the entire expression will be equal to [tex]0[/tex].

[tex]x-2=0\\(x+3)^2=0[/tex]

Set the first factor equal to [tex]0[/tex] and solve.

Set the first factor equal to [tex]0[/tex].

[tex]x-2=0[/tex]

Add [tex]2[/tex] to both sides of the equation.

[tex]x=2[/tex]

Set the next factor equal to [tex]0[/tex] and solve.

Set the next factor equal to [tex]0[/tex].

[tex](x+3)^2=0[/tex]

Set the [tex]x+3[/tex] equal to [tex]0.[/tex]

[tex]x+3=0[/tex]

Subtract [tex]-3[/tex] from both sides of the equation.

[tex]x=-3[/tex]

The final solution is all the values that make [tex](x-2)(x+3)^2=0[/tex] true.

[tex]x=2,-3[/tex]

For the 3 circles, in increasing order of the radius, we have:

For a circle of radius R, the arc defined by an angle θ (in degrees) is given by:

L = (θ/360°)*2pi*R

Where pi = 3.14

In this case, we have 3 circles of different radius, and θ = 60°, then we have:

circle 1:

radius = 1 unit, then:

L₁ = (60°/180°)*2*3.14*1 = 2.09

circle 2:

radius = 2 units, then:

L₂ = (60°/180°)*2*3.14*2 = 4.18

circle 3:

radius = 3 units, then:

L₃ = (60°/180°)*2*3.14*3 = 6.28

Answer:

Option B ([tex]42[/tex]) and D ([tex]t + 3 = 45[/tex])

Step-by-step explanation:

Step 1:  Multiply both sides by 15

[tex]\frac{t + 3}{15} = 3[/tex]

[tex]\frac{t + 3}{15} * 15 = 3 * 15[/tex]

[tex]t+3=45[/tex]

Step 2:  Subtract 3 from both sides

[tex]t + 3 -3 = 45 -3[/tex]

[tex]t = 42[/tex]

The number 4 represents the initially held water of the bucket. Then the correct option is B.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A bucket holding several inches of water was placed under a leaking faucet.

Water leaking into the bucket so that the level of the water in the bucket increased by a certain number of inches per hour.

The equation y = 2x + 4 represents this situation, where x is the number of hours and y is the number of inches of water in the bucket.

Then the number 4 in the equation represents.

The number 4 represents the initially held water of the bucket.

Answer:

Correlation analysis is used to quantify the degree to which two variables are related.

Step-by-step explanation:

In research, correlation analysis is a statistical approach for calculating and measuring the strength of a linear relationship between two variables. Simply defined, correlation analysis determines how much one variable changes as a result of the change in the other. A high correlation indicates a strong association between two variables, whereas a low correlation indicates a weak relationship.

Answer: 38

Step-by-step explanation:

Since the polygons are similar, the corresponding sides are all in the same proportions.

Solving for x

[tex]\frac{x-2}{4.5}=\frac{48}{6}[/tex]

[tex]\frac{x-2}{4.5}=8[/tex]

[tex]\frac{4.5\left(x-2\right)}{4.5}=8\cdot \:4.5[/tex]

According to the given question, we are to convert 8 1/4 quartz to gallons

According to the standard conversion

1 gallons = 4 quarts

x = 8.25 quartz

Take the ratio

1/x = 4/8.25
4x = 8.25

x = 8.25/4

x = 2.0625 gallons

Hence the total number of gallons in 8.25 quartz is 2.0625 gallons
