A solution in a book demonstrates the following:


79z = 92x + 9y (values for z, x and y are in between 0 and 10)


Modulo 9, this gives -2z ≡ 2x and by multiplying both sides by 5 gives -z ≡ x. Since 1 ≤ x ≤ 9, we have z = 9 - x.



Can someone please explain how taking Modulo 9 of the equation above leads to these results in detail. Thanks.

Answers

Answer 1

Answer:

In modular arithmetic, the modulo operation is used to find the remainder when one number is divided by another. For example, the expression "9 % 3" would evaluate to 0 because 9 divided by 3 leaves a remainder of 0.

In the given equation, taking the modulo 9 of both sides gives:

79z % 9 ≡ 92x + 9y % 9

The modulo operation distributes over addition, so we can simplify this to:

(79z % 9) ≡ (92x % 9) + (9y % 9)

Since any number divided by 9 has a remainder of itself, we can simplify this further to:

(z % 9) ≡ (2x % 9) + (y % 9)

This gives us the result:

-2z % 9 ≡ 2x % 9

Multiplying both sides by 5 gives:

(-2z % 9) * 5 ≡ (2x % 9) * 5

Which simplifies to:

-z % 9 ≡ x % 9

Since x is between 0 and 10, we know that x % 9 is between 0 and 9. Therefore, we can conclude that z = 9 - x.

The big-o estimate for each of these functions are:

nlog(n^2 + 1) = o (n^2 logn)

What is the big O notation?

It is a commonly used notation in algorithms and data structures domain to get an approximate upper bound of the time the algorithm in question will take to run.

For example, if you want to find the maximum element in a list of n elements, the worst case scenario is that the maximum is the last number. Then we write  O(n) .

How do you calculate big O notation for a function?

If the function is not too unweildy, it's pretty easy to do.

Consider the function f(x) = 4x^3 + (7x^2)(log(x)) + 3x +8

Look for the highest order term - the term that grows faster than the other terms, as x gets larger. For this function, that term is 4x^3.

Now just get rid of the constant out front to get x^3.

Then put a Big O in front: O( x^3 ).

So we say that f(x) is O( x^3 ).

Since,

nlog(n^2 + 1 ) + n^2 logn is approximately equals to n^2logn

which implies,

nlog(n^2 + 1) + (n^2 logn) = O (n^2 logn)

The attached picture is of a similar problem. But different radii.

Notice how you can form 2 equilateral triangles, and that there are 4 semi circles (at AC, AD, BC, BD).

This is because points C and D lie on the circumference of the circles. So distance from centres( A and b) to C and D are the radius

To get the area of your shaded section, you would just need to add up the areas of the 4 semi circles and 2 equi. triangles.

To get the area of a semi circle, work out the area of one of the sectors, i.e sector ABC, then subtract area of an equilateral triangle.

(Note, due to symmetry all semi circles have same area)

________________________________________________________

For example, for the picture below:

Area of equi triangle = absinC = 1*1*sin60 = √(3)   --> (C is angle)

Area of sector = (angle/360) * πr² = (60/360) * π * (1)² = π/6

So area of 1 semi circle = Area of Sector - Area of equi triangle

                                       = π/6 - √(3)

Now you would just add the areas of 4 semi circles, and 2 equi triangles, and compare coefficients to get a, b, c.

Enola wants to invest $8,600.00 in a savings account that pays 5.1% simple interest.

How many years will it take for this investment to triple in value?

Round your answer to the nearest tenth of a year.

It will take ________ years for this investment to triple in value.

Answers

Step-by-step explanation:

To find the number of years it will take for Enola's investment to triple in value, we can use the formula for simple interest:

I = P * r * t

where I is the total interest earned, P is the principal (the initial amount invested), r is the interest rate, and t is the number of years.

Since the investment will triple in value, the total interest earned will be equal to two times the initial investment, or 2 * $8,600.00 = $17,200.00. Substituting these values into the formula and solving for t, we get:

$17,200.00 = $8,600.00 * 5.1% * t

t = $17,200.00 / ($8,600.00 * 5.1%) = 3.28 years

Rounding this value to the nearest tenth of a year, we get t = 3.3 years. Therefore, it will take approximately 3.3 years for Enola's investment to triple in value.

Step-by-step explanation:

You want the solutions to the following inequalities by any convenient method:

x(10x +19) ≤ 15(x +2)² > (3x +1)²

Comparison

We choose to rewrite these inequalities to be comparisons to zero. This is because our graphing calculator easily identifies the x-intercepts of a graph. We can look a the graph to tell where the function is above or below the x-axis.

f(x) = x(10x +19) -15; f(x) ≤ 0g(x) = (x +2)² -(3x +1)²; g(x) > 0

Graph

The attached graph shows the solutions to be ...

f(x) ≤ 0 for -2.5 ≤ x ≤ 0.6g(x) > 0 for -0.75 < x < 0.5

The values obtained for the first equation will be  x ≤ 3/5 and x ≤ -5/2 and the values obtained for the second equation will be x < 1/2 and x < -3/4.

What is inequality?

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.

As per the given inequalities in the question,

1.

x(10x + 19) ≤ 15

Firstly, simplify it to the simpler form,

10x² + 19x - 15 ≤ 0

Solve the quadratic equation,

D = b² - 4ac

= 19² - 4(10)(-15).

D = 961

Now, use the formula,

(-b±√D)/2a

√D = √961 = 31

(-19 ± 31)/2(10)

So, the roots are:

1.

(-19 + 31)/20 = 12/20 = 3/5

Or, x ≤ 3/5

2.

(-19 - 31)/20 = -50/20 = -5/2

Or, x ≤ -5/2

2.

(x + 2)² > (3x + 1)²

Simplify the equation first.

x² + 4x + 4 > 9x² + 6x + 1

x² - 9x² + 4x - 6x + 4 - 1 > 0

-8x² - 2x + 3 >

8x² + 2x - 3 < 0

Now, find the roots for the equation,

D = b² - 4ac

D = 4 + 96

D = 100

Now, use the formula,

(-b ± √D)/2a

(-2 ± 10)/16

So, the roots are:

1. (-2 + 10)/16 = 1/2

Or, x < 1/2

2. (-2 - 10)/16 = -12/16 = -3/4

Geometric mean of two line segments p and q is a line x such that it satisfies the formula x² = a × b or x/a = b/x.

To construct geometric mean, first simply draw a line segment and mark a point P anywhere on this line.

Mark the length of the line segment 'a' from the point P and mark the endpoint of 'a' as A. Now, in the same line, from the point P, mark the length of the given line 'c' and mark its endpoint as C.

Now, draw a perpendicular bisector of the resulting line PC. Then we get the midpoint of PC. Let this point be O.

Draw a semicircle with center O and the endpoints P and C.

Now draw a vertical perpendicular line from the point A until it cuts the semicircle. Let N be the point where this line touches the semicircle.

Now join P with N.

The shape of the graph of a function is the shape assumed by the graph of the function after the dataset generated by using the function is plotted on the coordinate plane. The shape in the graph of the question is a triangular shape.

What is a function?

A function is a direction used to map the values of an input variable of the function to the output variables.

The points in the attaches graph which are connected by lines are;

(0, 1.5), and (4.5, 0)

The joining of the above points in the attached graph, and the origin forms a triangular shape.

Details about the shape of the graph of a function

The graph of a function such as f(x) = -x² + 2·x + 3, is obtained by finding the values of the output values of the function, f(x) for each input value of the function, x as follows;

Nikola likes to play horseshoes, where players try to score a ringer by throwing a horseshoe so it lands around a post. A player gets 2 attempts each round. Let R represent the number of ringers that Nikola scores in a round. Here's the probability distribution of R along with summary statistics. R=# of ringers 0 1 2 P(R) 0.75 0.20 0.05 Mean: HR=0.3 Standard deviation: OR 0.56 Nikola gets 3 points for each ringer that he scores. Let X represent the number of points that Nikola gets from ringers in a round. What are the mean and standard deviation of X?

Answers

The mean and standard deviation of X are 0.9 and 1.68 points.

Since Nikola gets 3 points for each ringer which he scores, then total points he gets from ringers could be determined by multiplying the number of ringers by 3.

So, X = R * 3 = 3R

Where:

R = numbers of ringers

X = total points Nikola gets from ringers

Given:

Mean : μR = 0.3

Standard deviation : σR = 0.56

Thus, multiplying by 3 will effects the mean as follows:

μX = 3 (μR)

= 3 (0.3)

= 0.9

And, multiplying by 3 also will effects the standard deviation as follows:

σX = 3 (σR)

≈ 3 (0.56)

≈ 1.68

Hence, the mean of X is 0.9 and and the standard deviation of X is 1.68.

Time to think about your New Year's Resolution for the new year. Nora decided she needed more
exercise. She decided that starting with the first full week in 2023, she will do a 45-minute workout
four times a week ( four days during every seven-day week.) This means she will exercise four of the
days during the week of Jan, 1 through Jan. 7 and will do the same during the week from Jan. 8
through Jan. 14, etc. If Nora sticks to her resolution, what is the first possible date on which she will
complete 25 hours of exercise for the year?

Answers

The first possible date on which she will complete 25 hours of exercise for the year is on March 1.

How to calculate date?

In general, dates can refer to a specific day on the calendar, such as January 1 or December 31. Dates can also refer to a specific point in time, such as a specific hour, minute, or second. In some cases, dates can also refer to a specific period of time, such as a year, month, or week.

Since Nora plans to do a 45-minute workout four times a week,

she will exercise for a total of 4 * 45 minutes = 180 minutes per week.

This means that each week, she will exercise for a total of 180 / 60 = 3 hours.

To complete 25 hours of exercise for the year,

Nora will need to exercise for a total of 25 / 3 = 8.3 weeks.

The first possible date on which she will complete 25 hours of exercise is therefore 8.3 weeks after Jan 1,

Which is approximately 8.3 * 7 = 58 days after Jan 1.

Therefore, the first possible date on which Nora will complete 25 hours of exercise is 58 days after Jan 1, which is on March 1.

Overall, if Nora sticks to her New Year's resolution to exercise four times a week, the first possible date on which she will complete 25 hours of exercise for the year is on March 1.

Answers

The height of rectangular prism needed to reach the desired volume is 9 inches.

What is the volume of the rectangular prism?

The volume of a rectangular prism is the product of its three dimensions, that is volume = length × width × height.

V= l.w.h

l Length

w Width

h Height

Given :

volume of rectangular prism (v) 32,188.04 inches

length  of rectangular prism(l) 59.3 inches

width of rectangular prism(w) 59 inches

Since , V= l.w.h

32,188.04 = 59.3 * 59 * h

or h = 32188.04/59.3 * 59

or h = 32188.04/3498.2

or h = 9.2

Hence , the height of rectangular prism needed to reach the desired volume is 9 inches.
