Answer:

Sum of ages is 35

Since there are two persons and it says four years from now, each year 2 more years will be added on to the 35 so year 1: 2years Year 2:4years Year 3:6years Year 4 : 8years

35+8= 43

Remember that Melanie will be 5 years older ( which she should have already been)

so 43+5= 48 ( Melanie's age)

and 48-5 = 43 ( Her brother's age)

Answer:

x = 3     y = -1

Step-by-step explanation:

x - 5y = 8

x = 5y + 8

replace x with 5y + 8 in the other equation

4(5y + 8) + 5y = 7

20y + 32 + 5y = 7

25y = 7 - 32

25y = -25

y = -25/25

y = -1

x = 5(-1) + 8

x = -5 + 8

x = 3

Step-by-step explanation:

If you multiply two real numbers, you will get another real number. There is no possibility of ever getting anything other than another real number.

Among the subsets of the real number system, the set of irrational numbers is not closed under multiplication.

We have,

Real Numbers: The set of real numbers is closed under multiplication. When you multiply two real numbers, the result is always a real number. For example, multiplying any two real numbers, such as 3.14 and 2.5, gives 7.85, which is also a real number.

Whole Numbers: The set of whole numbers is closed under multiplication.

When you multiply two whole numbers, the result is always another whole number. For example, multiplying 3 and 5 gives 15, which is also a whole number.

Integers: The set of integers is closed under multiplication.

When you multiply two integers, the result is always another integer.

For example, multiplying -4 and 7 gives -28, which is also an integer.

Rational Numbers: The set of rational numbers is closed under multiplication.

When you multiply two rational numbers, the result is always another rational number.

A rational number can be expressed as a fraction p/q, where p and q are integers and q is not zero.

When you multiply two fractions, the numerator and denominator are both integers and as long as the denominator is not zero, the result will still be a rational number.

However, the set of irrational numbers is not closed under multiplication.

An irrational number is a number that cannot be expressed as a fraction of two integers.

When you multiply two irrational numbers, the result may or may not be irrational.

Example:

√2 (square root of 2) is an irrational number, and √2 * √2 = 2, which is a rational number (integer 2).

So, the product of two irrational numbers (√2 * √2) is a rational number, not an irrational number.

Thus,

All subsets of the real number system (real numbers, whole numbers, integers, and rational numbers) are closed under multiplication, except for the subset of irrational numbers, which is not closed under multiplication.

Using translation concepts, the note E would be louder with a higher amplitude of y, hence constant a has to be multiplied by a positive constant greater than 1.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, the function is given by:

y = asin(1320πx)

The intensity of a sound is given by it's amplitude a, hence, to make the sound stronger, we need to vertically stretch the graph of y, which is done when constant a is multiplied by a positive constant greater than 1.

Answer:

Part A: School A Interquartile range = 9.5. School B Interquartile range = 7.5

Part B: There are no outliers present for either data set.

Step-by-step explanation:

For Part A, school A interquantile range is 9.5. Five number summary of school A is minimum = 6, quarantine q1= 6.5, median = 14, quarantine q3 = 16, and maximum = 17. Calculate Q3-Q1 = 16 - 6.5 which gives you 9.5

For School B, the interquartile range is 7.5. Five number of summary of school B is minimum = 5, quarantine q1 = 8, median = 12, quarantine q3= 15.5, maximum = 19. IQR Range = Q3-Q1 = 15.5 - 8. Which gives you 7.5

For Part B: All the outcomes of school A in between the values of -7.75 and 30.25. So this means there is no outliers in school A. For school B, all the outcomes of school B in between the values of -3.25 and 26.75. So there are no outlines in school B.

Answer:

The zeros are x =5, -7/2

Step-by-step explanation:

To find the zeros, set the expression equal to zero

(x-5)(2x+7) =0

Using the zero product property

(x-5)=0     (2x+7)=0

Solve each equation

x=5               2x = -7

x=5                  x = -7/2

The zeros are x =5, -7/2

Answer:

5, -7/2

Step-by-step explanation:

[tex]x - 5 = 0 = 5\\\\2x + 7 = 0\\2x + -7 = 0\\\frac{2x}{2} = \frac{-7}{2}\\ x = \frac{-7}{2}\\x = -\frac{7}{2}[/tex]

The standard deviation of the distribution of means is generally smaller than the standard deviation of the population of individuals.

The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.

The population of individuals is always smaller than the entire population, therefore the possibilities for variances will be lower with the sample than with the population. The higher the population, the greater the chances for deviation from the mean.

Therefore, the standard deviation of the distribution of means is generally smaller than the standard deviation of the population of individuals.

The equation can be simplified and written in a slope-intercept form as: [tex]y=18 \sqrt{3} x-6(\sqrt{3} \pi-1)[/tex]

To find the equation:

When we differentiate the function [tex]y=6 \sec (x)-12 \cos (x)[/tex], we get:

[tex]\begin{aligned}y^{\prime} &=\frac{d}{d x}(6 \sec (x)-12 \cos (x)) \\&=6 \frac{d}{d x}(\sec (x))-12 \frac{d}{d x}(\cos (x)) \\&=6 \sec (x) \tan (x)+12 \sin (x)\end{aligned}[/tex]

The slope of the tangent line is given by this derivative at the point [tex]x=\frac{\pi}{3}[/tex]:

As a result, this tangent line has the equation: [tex]y-6=18 \sqrt{3}\left(x-\frac{\pi}{3}\right)[/tex]

Since she wants to put a wire fence around her garden which is 12 feet long and 6 feet wide, the total perimeter will be:

= 2(length + width)

= 2(12 + 6)

= 36 feet

Therefore, the cost will be:

= Total feet × Amount

Terms of a Polynomial

So, each part of a polynomial in an equation is a term. For example, in a polynomial, say, 2x2 + 5 +4, the number of terms will be 3.

Given that Point E is the midpoint of line segment YT, the numerical value of x is 2.

A midpoint is simply a point that divides a segment into two equal halves.

Given the data in the question;

Point E is the midpoint of line segment YT, YT is divided into two equal halves. Hence, Two times Line segment YE equals to YT.

2( Line segment YE ) = Line segment YT

Plug in the given values and solve for x.

2( Line segment YE ) = Line segment YT

2( 3x + 1 ) = 14

Expand using distributive property

2 × 3x + 2 × 1 = 14

6x + 2 = 14

Collect like terms

6x = 14 - 2

6x = 12

6x/6 = 12/6

x = 12/6

x = 2

Given that Point E is the midpoint of line segment YT, the numerical value of x is 2.

The correct question is -

What is the maximum resultant intensity in terms of the intensity of the initial unpolarized incoming light I₀.

Step-by-step explanation:

So for questions 1 through 4, you're basically finding the number in the middle of the two letters. In question 1, D is above 7 on the number line and E is above 11. The mid-point would be 9.

For 5 and 6, we'll be using this formula: [tex](\frac{x_{1} + x_{2}}{2},\frac{y_{1} + y_{2}}{2})[/tex]

And now we just plug in the numbers from question 5 but it works the same way on 6 as well.

[tex](\frac{3 + 5}{2},\frac{1 + 3}{2})[/tex]     => (8/2, 4/2)

Coordinate of the midpoint would be (4, 2).

Lastly, we follow this system in order to get the final answers:

(Answer below shown for question 7)

(x + 2)/2 = 5

x + 2 = 10

x = 8

(y + 0)/2 = 2

y + 0 = 4

y = 4

Missing endpoint is (8, 4)

After simplifying the expression, - ( 7 x - 3 y ) + 2 ( 3/4 x + 1/2 y), we get the result as - 11 / 2 x + 4 y.

- ( 7 x - 3 y ) + 2 ( 3/4 x + 1/2 y)

First we will multiply 2 and open the brackets.

So, we get that:

- 7 x + 3 y + 3/2 x + y

Combining the like terms, we get that:

= ( - 14 + 3 ) x / 2 + 3 y + y

Simplifying and solving the expression to obtain the result, we get that:

= - 11 / 2 x + 4 y.

Therefore, after simplifying the expression, - ( 7 x - 3 y ) + 2 ( 3/4 x + 1/2 y), we get the result as - 11 / 2 x + 4 y.
