The value of the function f(-2) is (a) -1

From the question, we have the following parameters that can be used in our computation:

f(x) = [x³,  x < -3

        | 2x² - 9, x > -3

        { 5x+4, x ≥ 4

To calculate the function f(-2), we make use of the domain

x > -3

This is because

-2 > -3

So, we have

f(x) = 2x² - 9

Substitute the known values in the above equation, so, we have the following representation

f(-2) = 2(-2)² - 9

Evaluate

f(-2) = -1

Hence, the function is (a) -1

Answer:

Mode) 7

Median) 6

Mean) 5.2

Range) 7

Step-by-step explanation:

Let's start with what we have:

3, 7, 2, 4, 7, 5, 7, 1, 8, 8

a) The first part of the question we have to do is figure out the mode. The mode of a group of numbers is the number most repeated, which in this case is:

Mode) 7

b) The median of a data set is the number in the middle when ordered from least to greatest. When reordering it, we get:

1,2,3,4,5,7,7,7,8,8

So the number in the middle is...

There is no number in the middle so we have to find the mean of the middlemost numbers which are 5 and 7. Calculating (5 + 7)/2 we get 6, so.

Median) 6

c) The mean of a data set is when we add up all the numbers and then divide by the number of numbers, in this case, is 10. The sum of the numbers is 52. When dividing 52 by 10 we get:

Mode) 5.2

d) The range of a data set is the difference between the greatest number and the smallest number. When subtracting 1 from 8 we get:

A function is a mathematical expression that describes the relationship between an input and an output.

The function table is a visual, graded table with cells for input and cells for output that are organized into rows and columns.

Function tables have three variables components. There is the input, the function and the output. Function tables are created so that one of the three components is unknown and the other two serve as the clues to solving the table.

The rule of a function table is the mathematical operation that describes the relationship between the input and the output. The rule must be consistently applied to all input/output parts.

A traditional function table is made using two rows, with the top row being the input cells and bottom row being the ouput celss. Each column represents a signal input/output relationship.

According to the given statement, there were 58 children, 29 adults and 64 students.

Algebraically speaking, an equation is indeed a statement that establishes the equivalence of two mathematical equations.

Let there be x number of children, y number of students and x/2 number of adults. Forming the first equation based on number of students -

x + y + x/2 = 151 : Equation 1

Multiply equation 1 with 2

2x + 2y + x = 302 : Equation 2

3x + 2y = 302 : Equation 3

y = (302 - 3x)/2 : Equation 4

Forming second equation based on cost -

5x + 7y + 12x/2 = 1086 : Equation 5

Rewriting this equation

5x + 7y + 6x = 1086 : Equation 6

11x + 7y = 1086 : Equation 7

Keep the value of y from equation 4 in equation 7

11x + 7(302 - 3x)/2 = 1086

11x + (2114 - 21x)/2 = 1086

22x + 2114 - 21x = 2172

x = 2172 - 2114

x = 58

Now,

y = (302 - 3x)/2

y = (302 - 3×58)/2

y = 128/2

y = 64

Number of adults = 58/2

Number of adults = 29

Thus, there were 58 children, 29 adults and 64 students.

Answer: c, 84

Step-by-step explanation:

Answer:

(a + 7)(a² + 15a + 59) + 0 = a³ + 15a² + 59a + 12

Step-by-step explanation:

To solve this problem, we can use the long division method.

First, we need to divide the first term of the dividend, which is a³, by the first term of the divisor, which is a. This gives us a quotient of a² with a remainder of 0. We write this as follows:
a³ + 15a² + 59a + 12

a + 7 |

—————

a²  | 0

Next, we multiply the divisor by the quotient and subtract it from the dividend, giving us a new dividend of 15a² + 59a + 12. We write this as follows:

a³ + 15a² + 59a + 12

a + 7 |

—————

a²  | 0

 -  |

a²  | 15a² + 59a + 12

Next, we divide the first term of the new dividend, which is 15a², by the first term of the divisor, which is a. This gives us a quotient of 15a with a remainder of 0. We write this as follows:
a³ + 15a² + 59a + 12

a + 7 |

—————

a²  | 0

 -  |

a²  | 15a² + 59a + 12

   |

   | 15a | 0

Next, we multiply the divisor by the quotient and subtract it from the dividend, giving us a new dividend of 59a + 12. We write this as follows:

a³ + 15a² + 59a + 12

a + 7 |

—————

a²  | 0

 -  |

a²  | 15a² + 59a + 12

   |

   | 15a | 0

    -  |

   15a | 59a + 12

Finally, we divide the first term of the new dividend, which is 59a, by the first term of the divisor, which is a. This gives us a quotient of 59 with a remainder of 0. We write this as follows:
a³ + 15a² + 59a + 12

a + 7 |

—————

a²  | 0

 -  |

a²  | 15a² + 59a + 12

   |

   | 15a | 0

    -  |

   15a | 59a + 12

      |

      | 59 | 0

Since the remainder is 0, this means that the expression (a³ + 15a² + 59a + 12) is divisible by (a + 7). Therefore, the quotient is:

a³ + 15a² + 59a + 12

a + 7

—————

a² + 15a + 59

We can check our answer by multiplying the divisor by the quotient and adding the remainder (which is 0), and verifying that the result is equal to the original dividend
(a + 7)(a² + 15a + 59) + 0 = a³ + 15a² + 59a + 12

Linkage occurs when on the same chromosome, two genes are closer to each other . On the other hand, Crossing Over takes place when on the same chromosome, two genes are located far apart. Crossing Over may disturb the gene groups made by Linkage.

What is a linkage?

Linkage is the propensity of inheriting genes together on the same chromosome. It is a process in which genes are kept within a chromosome, so that it can be inherited together.

What is a crossing over?

Crossing over is a process of segregation of genes on the chromosome. It further sub-divides the chromosome into its component gametes.

Both, the process of linkage and crossing over are somewhat related to each other, but are yet different phenomenon. Genes are segregated into gametes through the process of crossing over. The lesser the distance in the same chromosome, the lesser is the chance of them being segregated through crossing over.

The equation of a line whose slope is 3/6 and passes through (8, 4) is y- 4 = 3/6(x -8).

The equation of a line:

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system. The numerous points which together form a line in the coordinate axis are represented as a set of variables x, and y to form an algebraic equation, which is referred to as an equation of a line.

Here we have to find the equation of a line.

Data given:

The slope (m) = 3/6

The point = (8,4)

The general formula for the equation of a line:

y - y1 = m( x - x1)

Where (x1, y1) is the point on the line.

As it is given that the point is ( 8, 4) and the slope is 3/6, so we have,

y - 4 = 3/6(x - 8)

Therefore the equation of a line is y-4 = 3/6(x -8).

By calculating the equation LHS ≠ RHS, the answer is No solution.

What are the solutions to this system?

There are three types of systems of linear equations in two variables, and three types of solutions:

An independent system has exactly one solution pair (x,y). The point where the two lines intersect is the only solution.

An inconsistent system has no solution.

A dependent system has infinitely many solutions.

For this, you can substitute one of the y's with the other equation

-2x + 2 = -2x - 2

Add 2x to both sides

2 = 0x - 2

Add 2 to both sides

4 = 0

Since 2 does not equal 0 the answer is No solution

What is intercepts?

A y-intercept, also known as a vertical intercept, is a point in analytical geometry where the graph of a function or relation intersects the y-axis of the coordinate system, using the convention that the horizontal axis represents a variable x and the vertical axis represents a variable y. Thus,

x = 0 is satisfied at these points.

y - intercept is the point which crosses the y - axis.

Since y - intercept is when x = 0

From the table the first point is x = 0.

The measure of each of the acute angles of the right triangle is 32° and 58°.

A right triangle is a kind of triangle which has a right angle (90°) and two acute angles (less than 90°).

Let x = measure of one of the acute angles

If the measure of one acute angle of a right triangle is 6 less than twice the measure of the other acute angle, then

measure of the other acute angle = 2x - 6

The sum of all the angles of any triangle is equal to 180°. Hence,

90° + x + 2x - 6 = 180°

Solve for the value of x.

3x = 96

x = 32

Solve for the measure of the other acute angle.
