Change the denominator to 16 so it can be common with n

1/2

1x8/2x8

8/16

3/4

3x4/4x4

14/16

Now we look at the numerators and see the new ones are 8 and 14 so all the numbers in between 8 and 14 are 9,10,11, 12, and 13

Hopes this helps please mark brainliest

The possible values of n are 9, 10, and 11.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

1/2 < n/16 < 3/4

Now,

Take 1/2 < n/16

1/2 < n/16

16/2 < n

8 < n ____(1)

Take n/16 < 3/4

n/16 < 3/4

n < 3/4 x 16

n < 12 ______(2)

From (1) and (2) we get,

8 < n < 12

This means,

The possible values of n are 9, 10, and 11.

Thus,

n values are 9, 10, and 11.

Answer:

x = 4 and y = 3

Step-by-step explanation:

You are looking for the value of x and y when: 2x - 3y = -1 and y = x - 1

Because you are given y in terms of x (the second equation given), substitute that into the first equation for y:

2x - 3y = -1 when y = x - 1

2x - 3(x - 1) = -1

expand left side:

2x - 3x + 3 = -1

combine x terms on left side:

-x + 3 = -1

subtract 3 from both sides:

-x + 3 - 3 = -1  - 3

-x = -4

divide both sides by -1:

-x/-1 = -4/-1

x = 4

now use x = 4 in one of the original equations to solve for y. For simplicity sake, we will use the second equation but the answer can also be found by substituting x = 4 into the first equation.

y = x - 1 when x = 4

y = 4 - 1

y = 3

Answer:

x = 4; y = 3

Step-by-step explanation:

2x - 3y = -1

y = x - 1

Copy the first equation.

Subtract x from both sides of the second equation and multiply both sides by 3. Write it below the first equation. Then add the equations eliminating y. Solve for x.

     2x - 3y = -1

+   -3x + 3y = -3

----------------------

      -x        = -4

x = 4

Now substitute 4 for x in the second original equation and solve for y.

y = x - 1

y = 4 - 1

y = 3

Answer: x = 4; y = 3

The total time the ball is in the air, with an initial velocity of 19.62m/s is 3.972seconds.

What is velocity?

The rate of change in an object's position with regard to a frame of reference and time is what is meant by velocity, according to its definition. Although it may appear difficult, velocity is essentially speeding in a particular direction. Due to the fact that it is a vector quantity, velocity must be defined in terms of both magnitude (speed) and direction. It is measured in meters per second in the SI (ms-1). A body is considered to be accelerating if its velocity changes, either in magnitude or direction.

Solution Explained:

Given,
initial velocity (v) = 19.62m/s
time taken to reach maximum height ( [tex]t_{h}[/tex]) = 2.01s

We assume, acceleration (a) = 10 m/s^2

We know,
v = at
t = v/a
t = 19.62 / 10                        (replacing with values)
t = 1.962s

total time = [tex]t_{h}[/tex] + t
                = 2.01 + 1.962
                = 3.972

Therefore, the total time the ball is in the air is for 3.972seconds.

Answer:

Each movie costs $3.75 while each video game costs $5.50.

Step-by-step explanation:

Let the cost of each movie and the cost of each video game be $x and $y respectively.

6x + 5y = 50 ------ equation (1)

2x + 3y = 24 ------ equation (2)

Subtract 3 times of equation (2) from equation (1):

(6x + 5y) - 3(2x + 3y) = 50 - 3(24)

    6x + 5y -  6x - 9y = 50 - 72

                           -4y = -22

                            4y = 22

                           ∴ y = 5.5

Substitute y = 5.5 into equation (2):

2x + 3(5.5) = 24

            2x = 7.5

           ∴ x = 3.75

What is the area of a rectangle?

The area of the rectangle is the region enclosed by the perimeter of the rectangle and is equal to the product of length and width.

i.e. Area (A) = length(l) * width (w)

Given, a deck measurement is 12 feet by 10 feet

i.e. length (l) = 12 feet

width(w) = 10 feet

Area of deck (A) = 12*10 = 120 square feet

Let 'x' be the increased dimensions then,

new length = (12 + x) feet

new width = (10+x) feet

And, area of new dimensions = 3*120 = 360 square feet

So,  [tex](12 + x)*(10+x) = 360[/tex]

or, [tex]120+12x + 10x + x^{2} =360[/tex]

or, [tex]x^{2}+ 22x+120-360=0[/tex]

As per the population function, the population of mosquitoes in the area at any time is 400000 = 200000e⁷ˣ

Population function:

Population function means  the effective population served over the course of a time

Given,

The population of mosquitoes in a certain area increases at a rate proportional to the current population, and in the absence of other factors, the population doubles each week. There are 200000 mosquitoes in the area initially , and predators (birds, bats, and so forth) eat 20000 mosquitoes/day.

Here we need to determine the population of mosquitoes in the area at any time.

Here we have to note that we have two time frames in the information given; weeks and days.

Now, we want the population after predation lets choose time in days.

We know that the population doubles every seven days (ignoring predation) so if P(t) is the population function we have IVP

So, for one week, the population function of the given situation is,

=> dP/dt = rP

=> P(0) = 200000

And we know that,

=> P(7) = 2P(0)

While we solving the IVP for P then we get

[tex]P=Ce^{rt}[/tex]

While we apply,  P(0) = 200,000 then we get the value of C = 200,000

So, the given function is rewritten as

[tex]P=200000e^{rt}[/tex]

Now we have to use P(7) = 2P(0), then we get,

400000 = 200000e⁷ˣ

Therefore, we have to use this function to find the population of mosquitoes in the area anytime.

Step-by-step explanation:

1. First things first, the binomial tells us the zeroes.

[tex] - (x - 2) {}^{2} = 0[/tex]

[tex](x - 2) {}^{2} = 0[/tex]

[tex]x - 2 = 0[/tex]

[tex]x = 2[/tex]

This root has a multiplicity of 2, so this root will "bounces off the x axis"

[tex](x + 4) = 0[/tex]

[tex]x = - 4[/tex]

Our x intercepts are

2 and -4

This root has a multiplicty of 1, so it will cross thorough the x axis.

Our leading degree is odd and we have a negative leading coefficient so

as x approaches ♾️, f(x) approaches negative ♾️

and as x approaches negative ♾️, f(x) approaches ♾️.

Our y intercept can be found by letting x=0,

so

[tex] - (0 - 2) {}^{2} (0 + 4) = - ( - 2) {}^{2} (0 + 4) = - (4)(4) = - 16[/tex]

So our y intercept is -16.

For Rational Functions, if the numerator and denominator share the same factor they are considered a removable discontinuity or hole.

Set it equal to 0.

[tex]x + 5 = 0[/tex]

[tex]x = - 5[/tex]

So we have a hole at x=-5.

Next, simplify the fraction.

[tex] \frac{x - 4}{x - 6} [/tex]

Now, plug in -5

[tex] \frac{ - 5 - 4}{ - 5 - 6} = \frac{ - 9}{ - 11} = \frac{9}{11} [/tex]

So we have a hole at (-5,9/11).

To find y intercept, let x=0,

[tex] \frac{0 - 4}{0 - 6} = \frac{2}{3} [/tex]

To find Vertical Asymptote, set denominator equal to 0

[tex]x - 6 = 0[/tex]

[tex]x = 6[/tex]

Draw a vertical dotted line at x=6

To find HA, this is the only case since the numerator and denominator has the same degree.

So using the leading coefficients, divide the numerator leading coefficient/ denominator leading coefficient.

The leading coefficient for both is 1 so

[tex]ha = \frac{1}{1} [/tex]

So our HA is y=1.

Draw a horizon tal dotted line at y=1

We have no slope asymptote.

The graph is above.

Part 3:

(3x-1)(2x+1)>0

[tex]3x - 1 = 0[/tex]

[tex]3x = 1[/tex]

[tex]x = \frac{1}{3} [/tex]

[tex]2x + 1 = 0[/tex]

[tex]2x = - 1[/tex]

[tex]x = - \frac{1}{2} [/tex]

We have three possible regions, when x is positive

Pick a random number less than -1/2 and plug it in the inequality to see if it true.

Let use -1

[tex](3( - 1) - 1)(2( - 1) + 1) = ( - 4)( - 1) = 4[/tex]

Since 4>0, Whenever x is less than -1/2, the function is positive (greater than zero)

Let's try the next region.

Let use 0

[tex](3(0) - 1)(2(0) + 1) = ( - 1)(1) = - 1[/tex]

So this solution won't work

Let try the next region, let use 1.

[tex](3(1) - 1)(2(1) + 1) = (2)(3) = 6[/tex]

Since 6>0, Whenever x is greater than 1/3, the function is positive(greater than zero).

Our answer is

(-oo,-1/2) U (1/3,oo).

Part 4:

We know x cannot be -2 because

[tex]x + 2 = 0[/tex]

[tex]x = - 2[/tex]

So -2 can not be in our answer.

[tex] \frac{x - 1}{x + 2} \leqslant 2[/tex]

[tex]x - 1 \leqslant 2(x + 2)[/tex]

[tex]x - 1 \leqslant 2x + 4[/tex]

[tex] - 5 \leqslant x[/tex]

So

[tex]x \geqslant - 5[/tex]

However x can not be -2. so we say

When reflecting over the [tex]y[/tex] axis, [tex]f(x) \to f(-x)[/tex].

[tex]f(x)=|x+1|-2 \implies g(x)=|-x+1|-2[/tex]

The equation would be g(x) = |-x+1| -2 reflecting the function over the y-axis.

Reflection across the y-axis is defined as reflecting a point across they = x,  the x-coordinate, and y-coordinate places, the line y = -x is the coordinates (-x, y).

So reflected across the y-axis: f(x) → f(-x),

⇒ (x,y) → (-x , y)

The function is given in the question

f(x) = |x+1| -2

We know that the reflected across the y-axis: f(x) → f(-x),

g(x) = f(-x)

g(x) = |-x+1| -2
