The cone will fit in 4 times and the volume of the cone is 535.89 in³

To solve this problem, we have to find the volume of the cone and the volume of the sphere.

The formula of volume of a cone is given as;

V = 1/3πr²h

We need to calculate the volume of the sphere which is given as

V = 4/3 πr³

The volume of the ball = 4/3 * 3.14 * 8³ = 2143.57in³

The volume of the cone = 1/3 * 3.14 * 8² * 8 = 535.89 in³

The number of times it will fit into will be 2143.57 / 535.89 = 4

It will fit in 4 times

Answer:

Step-by-step explanation:

.40x + .65 ≤3.50

(3, 4)  I think it is a solution to the inequality. Because when you graph it (3, 4) looks like it is shaded meaning that it is a solution. (If wrong, I'm sorry)

The inequality that represents the numbers of apples and pears you can buy is 0.40x + 0.65y ≤ 3.50.

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Given;

The cost of the apples = $0.40 per apple

So, the cost of x apples is 0.40x.

The cost of the pears = $0.65 per pear

So, the cost of y pears is 0.65y.

The total cost of the apples and pears is the sum of the cost of the apples and the cost of the pears, which is 0.40x + 0.65y;

Since we can spend at most $3.50 at the market, the total cost of the apples and pears must be less than or equal to $3.50;

Therefore, the inequality that represents the numbers of apples and pears you can buy will be 0.40x + 0.65y ≤ 3.50;

Answer:

She will have a balance of more than $18 for up to 6 days

Step-by-step explanation:

Start with $30.

Each day, x, subtract $1.99 from $30.

30 - 1.99x

The amount must be greater than $18.

30 - 1.99x > 18

Subtract 30 from both sides.

-1.99x > -12

Divide both sides by -1.99. Remember than when you multiply or divide both sides of an inequality by a negative number, the inequality sign changes direction.

-1.99x/(-1.99) < -12/(-1.99)

x < 6.03

The number of days must be less than 6.03. Since we deal with whole days, she will have a balance of more than $18 for up to 6 days.

In the case of regression analysis, the dependent variable must be metric; in multiple discriminant analysis, the dependent variable is nominal in nature. (Option B)

Regression analysis refers to a collection of statistical methods which are used for the estimation of relationships between a dependent variable and one or more independent variables. It can used to assess the strength of the relationship between variables and for modeling their future relationship. In regression analysis the dependent variable is metrically scaled (where distance between values can be calculated). Multiple discriminant analysis is a regression technique used in statistics to group objects into categories for analysis. In multiple discriminant analysis the dependent variable is nominally scaled (where characteristics can be distinguished).

The graph of cubic equations, a to d and the associated cubic equations are as follows;

Equation (B) ⇒ Graph a

Equation (C)  ⇒ Graph b

Equation (D) ⇒ Graph c

Equation (A) ⇒ Graph d

A cubic equation that has only one variable is an equation of the form a·x³ + b·x² + c·x + d, where a ≠ 0.

The evaluation of the graphs are as follows;

Graph a

The y-intercept of the graph a, is 1, and the x-intercept, which is a solution of the equation is x = -1,

Therefore, when x = 0, y = 1, and when y = 0, x = -1

The function in graph a represents the translation of the parent function, y = x³, one unit, upwards, which corresponds with the function;

y = x³ + 1

Therefore, graph a corresponds to cubic equation (B) y = x³ + 1

Graph b

The y-intercept is one (1), and the turning point is at the point x = -1, which represents a shift of one unit to the left, and which can be obtained by the equation; y = (x + 1)³

Therefore, graph b corresponds with the cubic equation (C) y = (x + 1)³

Graph c

The turning point of the graph and the y-intercept is shifted one unit down, which corresponds with the equation; (D) y = x³ - 1

Graph d

The turning point is shifted 1 unit to the right and is located on the x-axis, The y-intercept is located at the point y = 1, therefore, the graph corresponds with the equation y = (x - 1)³

Graph d corresponds to equation (A), y = (x - 1)³

Step-by-step explanation:

To find the derivative of f(x) = 3x² + 2x at x = 3, we can use the power rule:

f'(x) = 2*3x + 2

When x = 3, the derivative of f(x) is:

f'(3) = 2*3(3) + 2

f'(3) = 18 + 2

f'(3) = 20

Therefore, the derivative of f(x) = 3x² + 2x at x = 3 is f'(3) = 20.

Equation of parabola: y =ax² and receiver should be placed 18 feet above vertex.

Explanation:

Considering satellite dish as parabola we can have vertex as origin and concave upward.

So, equation of parabola will be justifying structure of satellite dish i.e

y = ax² -------(1)

Two points other than (0,0) are (-12,2) and (12,2), unit being feet.

This points will satisfy equation of parabola, substituting them in equation 1, we will calculate the value of constant 'a'.

a = [tex]\frac{2}{12^{2} }[/tex]

[tex]\frac{2}{2*6*12}\\ =\frac{1}{72}[/tex]

Substituting value of a = 1/72 in equation 1 we get

72y = x²

As receiver need to be located at focus, so it will be places at a distance of 'p' above the vertex

4p = 72

Dividing both sides by 4, we get

p = 18 feet

The cone would fit into the beachball two times, and has a volume of 134 in^3. Answers required are:

Blank 1 - two

Blank 2 - 134 in^3.

A beachball has the shape of a sphere, so that its volume can be determined by;

volume of a sphere = 4/3 [tex]\pi r^{3}[/tex]

where r is the radius of the sphere.

Given that the diameter of the beachball is 8 inches, then;

its radius = 8/ 2

               = 4 inches

volume of beachball = 4/3 x 22/7 x 4^3

                          = 268.19 cubic in.

The volume of a cone can be determined by;

volume of a cone = 1/3 [tex]\pi r^{2} h[/tex]

where r is its radius, and h is its height.

Given a cone of radius 4 inches and height 8 inches, then;

its volume = 1/3 x 22/7 x 4^2 x 8

                 = 134.1cubic inches

Thus,

268.19/ 134.10  = 1.999993

The solution to the system, as an ordered triple is: (3, -4, 6).

To solve the following given system of equations:

2x + y + 3z = 20 --> eqn. 1

x + 2y - z = -11 --> eqn. 2

3x - 2z = -3 --> eqn. 3

Multiply equation 1 by 2 to get eqn. 4:

4x + 2y + 6z = 40 --> eqn. 4

Subtract eqn. 4 from eqn. 2:

x + 2y - z = -11 --> eqn. 2

4x + 2y + 6z = 40 --> eqn. 4

-3x - 7z = -51 --> eqn. 5

Add equations 3 and 5 together:

3x - 2z = -3 --> eqn. 3

-3x - 7z = -51 --> eqn. 5

-9z = -54

z = -54/-9

z = 6

Substitute the value of z into equation 5:

-3x - 7(6) = -51 --> eqn. 5

-3x - 42 = -51

-3x = -51 + 42

-3x = -9

-3x/-3 = -9/-3

x = 3

Find the value of y by substituting the values of x and z into equation 1:

2(3) + y + 3(6) = 20 --> eqn. 1

6 + y + 18 = 20
