Answer:

Bjorn sends 12 messages.

Step-by-step explanation:

Bjorn sends b messages, while Irina sends six times as many messages as Bjorn, which means that Irina sends 6b messages. We also know that Irina sends 72 messages. Therefore, 6b must be equal to 72. If 6b = 72, b = 72/6, which simplifies to b being equal to 12.

Step-by-step explanation:

The value of r indicates the negative correlation.

Rikki decided to collect data to determine if a runner's time and speed are correlated.

She determined the data to have a correlation coefficient of -0. 5.

The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of the two variables.

She determined the data to have a correlation coefficient of -0. 5.

Here, the coefficient is negative which is -0.5.

This correlation coefficient indicates that there exists a weak negative correlation between the runner’s time and the speed.

This relation is negative because the correlation coefficient is negative.

Hence, The value of r indicates the negative correlation.

4x^2+8x+36=0

Factor out the GCF: 4

1/4(4x^2+8x+36=0)

x^2+2x+9=0

Solve using the Quadratic formula.

a= 1

b= 2

c= 9

[tex]x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

[tex]x = \frac{ -2 \pm \sqrt{2^2 - 4(1)(9)}}{2(1)}[/tex]

[tex]x = \frac{ -2 \pm \sqrt{4 - 36}}{2}[/tex]

There are no real solutions because you cannot square root a negative number.

The answer to the two questions about total surface area and lateral surface area are; Tripling the radius will increase the total surface area and the lateral surface area is 464.7 cm²

The formula for the total surface area of a right circular cone is;

T.S.A = πrl + πr²

4) Cone has the following dimensions;

Radius; r = 2.9 m

Slant Height; l = 13.8 m

Thus, if we triple the radius, we have;

T.S.A = π(3 * 2.9 * 13.8) + π(3 * 2.9)²

T.S.A = 195.75π

But if we triple the slant height, we have;

A = π(2.9 * 3 * 13.8) + π(2.9)²

A = 128.47π

Thus, tripling the radius will increase the surface area

B) Formula for lateral surface area of a cone is;

L.S.A = πrl

L.S.A = π * 14.8 * 10

L.S.A ≈ 464.7 cm²

Answer:

Step-by-step explanation:

Fracking can cause groundwater contamination. When companies or individuals frack for oil in areas close to residential living, they can leak chemicals or even oil retrieved from the Earth into local water sources (water tanks or wells). Carbon (or any pollutant) emissions can also contaminate groundwater. CO2 in the air can be absorbed by living organisms rooted in dirt/soil, leeching chemicals/pollutants into the ground and eventually into water sources.

Answer:

-b/2a is the equation to find the x coordinate of the vertex point and it's y, when x is plugged into the quadratic equation.

Step-by-step explanation:

The true statements about the dilation are as follows;

The scale factor is One-eighth

The coordinates of the C prime are (0.75, 0.5).

The coordinates of B prime are (–0.25, 1).

Given

A triangle has vertices at A(–2, 4), B(–2, 8), and C(6, 4).

If A prime has coordinates of (–0. 25, 0. 5) after the triangle has been dilated with a center of dilation about the origin.

Transformation is the movement of a point from its initial location to a new location. If an object is transformed then all its points are also transformed. Types of transformation are reflection, dilation, rotation, and translation.

Dilation is the enlargement or reduction in the size of an object. If a point X(x, y)  is dilated about the origin by a factor k, its new location is X'(kx, ky).

Triangle ABC with vertices at A(–2, 4), B(–2, 8), and C(6, 4) is dilated to give A'(-0.25, 0.5)

kA = A'

(-2k, 4k) = (-0.25, 0.5)

-2k = -0.25, hence k = 1/8

Therefore the scale factor is 1/8 (one- eight)

The new location of the vertices is B'(-0.25, 1), C'(0.75, 0.5)

Answer:

GCF: y³z³

Step-by-step explanation:

The greatest common factor is the a term that you can take out of all the terms given to you. This term, when multiplied to each of the individual numbers in the set, will return you to the original amount.

In this case, note that they all share the variables y and z, and that each of them have at least 3 y's and 3 z's. For you to factor, you will divide these from all the terms.

[tex]\frac{x^{3}y^{5}z^{5} , y^{3}z^{5} , xy^{3}z^{3} }{y^{3}z^{3}} = x^{3}y^{2}z^{2} , z^{2} , x[/tex]
