Step-by-step explanation:

[tex](3\sqrt{2} +4)(\sqrt{2} -1) = (3*2)+4\sqrt{2} -3\sqrt{2}-4[/tex]

[tex]= 6-4+\sqrt{2}[/tex]

[tex]= 2+\sqrt{2}[/tex]

Answer:

Step-by-step explanation:

Use FOIL method

(3√2 +  4)(√2 - 1) = 3√2*√2 - 3√2*1 + 4 *√2 - 4*1

                           =3*√(2*2) - 3√2 + 4√2 - 4

                           = 3*2 - 3√2 + 4√2 - 4

                           = 6 - 3√2 + 4√2 - 4  {add the like terms}

                          = 6 - 4 - 3√2 + 4√2

                          = 2 + √2

Answer: The model indicates that students who have spent 0 hours playing sports will have an average mood rating of 5

Step-by-step explanation:

A y-intercept of 5 means players spending 0 hours playing sports will have an average rating of 5.

Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables.

In this case, y is the rating of the mood on a scale from 0 to 10 while the x represents the number of hours in playing sports.

We know the y-intercept means the x-coordinate is 0 means the number of hours spent playing sports is 0.

So, a y-intercept of 5 means students who have spent 0 hours playing sports will have an average mood rating of 5.

Hence, a y-intercept of 5 means players spending 0 hours playing sports will have an average rating of 5.

Answer:

(x + 4)^2 + (y-9)^2 = 121

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 + (y-k) ^2 = r^2  where (h,k) is the center and r is the radius

(x - -4)^2 + (y-9)^2 = 11 ^2

(x + 4)^2 + (y-9)^2 = 11 ^2

(x + 4)^2 + (y-9)^2 = 121

Answer:

The range is 115

Step-by-step explanation: To find the range of a data set you subtract the lowest value from the highest value. In this case that would be 135 minus 20 which gives you a range of 115.

Depending on the particular body, there is a different formula and different required information you need to calculate its volume. Below are volume formulas for the most common types of geometric bodies - all of which are supported by our online volume calculator above. All measures need to be in the same unit. The result is always in cubic units: cubic centimeters, cubic inches, cubic meters, cubic feet, cubic yards, etc.

Volume calculations are useful in a lot of sciences, in construction work and planning, in cargo shipping, in climate control (e.g. air conditioning calculations), swimming pool management, and more.

LAST ONE IS angle JLK congruent to angle LNM, SAS

Step-by-step explanation:

The triangles JLK and LMN are similar by SAS congruence theorem, LJK≅ LNM.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

The triangles JLK and LMN are similar triangles.

Which means the sides are proportional and those angles are congruent.

We have to prove that JLK is similar to LMN.

By SAS rule we have "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".

So LJK≅ LNM.

Answer: (27- 4/3 pi) r^3

Step-by-step explanation: 1. Volume of a cube: V= a^3,  V= 3^3 , V=27

2.  Volume of a sphere: V=4/3 pi r^3 ......

The expression which represents the volume of the foam padding needed to fill the space in the box around the sphere in terms of π is option C. (27 - [tex]\frac{4}{3}[/tex] π) r³.

Volume of a three dimensional shape is the space occupied by the shape.

We have a sphere of radius r inside a cube of side length 3r.

Volume of a cube = (a)³, where a is the side length.

Here a = 3r

Volume of the cube = (3r)³ = 27r³

Volume of a sphere of radius r = [tex]\frac{4}{3}[/tex] π r³

Volume of the foam padding needed to fill the space in the box around the sphere = 27r³ - [tex]\frac{4}{3}[/tex] π r³

                  = r³ (27 -  [tex]\frac{4}{3}[/tex] π)

Hence the volume of the space inside the cube outside the sphere is r³ (27 -  [tex]\frac{4}{3}[/tex] π).
