Part 1) The function of the First graph is [tex]f(x)=(x-3)(x+1)[/tex]

Part 2) The function of the Second graph is [tex]f(x)=-2(x-1)(x+3)[/tex]

Part 3) The function of the Third graph is [tex]f(x)=0.5(x-6)(x+2)[/tex]

See the attached figure

Step-by-step explanation:

we know that

The quadratic equation in factored form is equal to

[tex]f(x)=a(x-c)(x-d)[/tex]

where

a is the leading coefficient

c and d are the roots or zeros of the function

Part 1) First graph

we know that

The solutions or zeros of the first graph are

x=-1 and x=3

The parabola open up, so the leading coefficient a is positive

The function is equal to

[tex]f(x)=a(x-3)(x+1)[/tex]

Find the value of the coefficient a

The vertex is equal to the point (1,-4)

substitute and solve for a

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

[tex]-4=a(-2)(2)[/tex]

[tex]a=1[/tex]

therefore

The function is equal to

[tex]f(x)=(x-3)(x+1)[/tex]

Part 2) Second graph

we know that

The solutions or zeros of the first graph are

x=-3 and x=1

The parabola open down, so the leading coefficient a is negative

The function is equal to

[tex]f(x)=a(x-1)(x+3)[/tex]

Find the value of the coefficient a

The vertex is equal to the point (-1,8)

substitute and solve for a

[tex]8=a(-1-1)(-1+3)[/tex]

[tex]8=a(-2)(2)[/tex]

[tex]a=-2[/tex]

therefore

The function is equal to

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

Part 3) Third graph

we know that

The solutions or zeros of the first graph are

x=-2 and x=6

The parabola open up, so the leading coefficient a is positive

The function is equal to

[tex]f(x)=a(x-6)(x+2)[/tex]

Find the value of the coefficient a

The vertex is equal to the point (2,-8)

substitute and solve for a

[tex]-8=a(2-6)(2+2)[/tex]

[tex]-8=a(-4)(4)[/tex]

[tex]a=0.5[/tex]

therefore

The function is equal to

[tex]f(x)=0.5(x-6)(x+2)[/tex]

Answer 2

For the first graph the function is f(x) = (x—3)(x + 1), for the second graph the function is f(x) = -2(x—1)(x + 3), and for the third graph the function is f(x) = 0.5(x-6)(x+2).

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

As we can see in the first graph, the x-intercepts are x = -1 and x = 3, and it is opening up-side, so the function:

f(x) = (x - 3)(x + 1)

Second graph: x-intercepts are x = -3 and x = 1 and opening down-side.

Also, the vertex is at (-1, 8) so the function:

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

Third graph: x-intercepts are x = -2 and x = 6, and it is opening up-side, Also the vertex is at (2, -8) so the function:

f(x) = 0.5(x-6)(x+2)

Thus, for the first graph the function is f(x) = (x—3)(x + 1), for the second graph the function is f(x) = -2(x—1)(x + 3), and for the third graph the function is f(x) = 0.5(x-6)(x+2).

Suppose θ is an angle in the standard position whose terminal side is in Quadrant IV and cot θ= -6/7 . Find the exact values of the five remaining trigonometric functions of θ. Show your work

Answers

Answer:

[tex]tan(\theta)=-\frac{7}{6}[/tex]

[tex]sec(\theta)=\frac{\sqrt{85} }{6}[/tex]

[tex]cos(\theta)=\frac{6\sqrt{85} }{85}[/tex]

[tex]sin(\theta)=-\frac{7\sqrt{85}}{85}[/tex]

[tex]cosec(\theta)=-\frac{\sqrt{85}}{7}[/tex]

Step-by-step explanation:

[tex]cot (\theta) = -\frac{6}{7}[/tex]

a) Since,

[tex]tan(\theta) = \frac{1}{cot(\theta)}[/tex]

[tex]tan(\theta) = \frac{1}{-\frac{6}{7} }=-\frac{7}{6}[/tex]

b) Also, according to the Pythagorean identity:

[tex]sec^{2}(\theta)=1+tan^{2}(\theta)[/tex]

Using the value of tan([tex]\theta[/tex]), we get:

[tex]sec^{2}(\theta)=1+(-\frac{7}{6} )^{2}\\\\ sec^{2}(\theta)=\frac{85}{36}\\\\ sec(\theta)=\pm \sqrt{\frac{85}{36} } \\\\ sec(\theta)=\pm \frac{\sqrt{85} }{6}[/tex]

Since, secant is positive in 4th quadrant, we will only consider the positive value. i.e.

[tex]sec(\theta)=\frac{\sqrt{85} }{6}[/tex]

c) Since,

[tex]cos(\theta)=\frac{1}{sec(\theta)}[/tex]

Using the value of secant, we get:

[tex]cos(\theta)=\frac{1}{\frac{\sqrt{85} }{6} } =\frac{6\sqrt{85} }{85}[/tex]

d) According to Pythagorean identity:

[tex]sin^{2}(\theta)=1-cos^{2}(\theta)\\sin(\theta)=\pm \sqrt{1-cos^{2}(\theta)}[/tex]

Since, sine is negative in fourth quadrant, we will consider the negative value. Using the value of cosine, we get:

[tex]sin(\theta)=-\sqrt{1-(\frac{6\sqrt{85} }{85})^{2}}=-\frac{7\sqrt{85}}{85}[/tex]

e) Since,

[tex]cosec(\theta)=\frac{1}{sin(\theta)}[/tex]

Using the value of sine, we get:

[tex]cosec(\theta)=\frac{1}{-\frac{7\sqrt{85} }{85}}=-\frac{\sqrt{85}}{7}[/tex]

Answer:

1. 2.12 seconds

Step-by-step explanation:

1. "Pekka tosses a ball out of a window that is 40 feet in the air.  Its initial velocity is 15 feet per second.  The path of the ball is represented by:

h = -16t² + 15t + 40

How long does it take for the ball to hit the ground (in seconds) rounded to the nearest hundredth?"

When the ball hits the ground, its height is 0:

0 = -16t² + 15t + 40

0 = 16t² − 15t − 40

Solve with quadratic formula:

t = [ -b ± √(b² − 4ac) ] / 2a

t = [ 15 ± √(225 + 2560) ] / 32

t ≈ 2.12 or -1.18

t must be positive, so t = 2.12 seconds.

Answer:

Choice A) [tex]F(x) = 3\sqrt{x + 1}[/tex].

Step-by-step explanation:

What are the changes that would bring [tex]G(x)[/tex] to [tex]F(x)[/tex]?

Translate [tex]G(x)[/tex] to the left by [tex]1[/tex] unit, andStretch [tex]G(x)[/tex] vertically (by a factor greater than [tex]1[/tex].)

[tex]G(x) = \sqrt{x}[/tex]. The choices of [tex]F(x)[/tex] listed here are related to [tex]G(x)[/tex]:

Choice A) [tex]F(x) = 3\;G(x+1)[/tex];Choice B) [tex]F(x) = 3\;G(x-1)[/tex];Choice C) [tex]F(x) = -3\;G(x+1)[/tex];Choice D) [tex]F(x) = -3\;G(x-1)[/tex].

The expression in the braces (for example [tex]x[/tex] as in [tex]G(x)[/tex]) is the independent variable.

To shift a function on a cartesian plane to the left by [tex]a[/tex] units, add [tex]a[/tex] to its independent variable. Think about how [tex](x-a)[/tex], which is to the left of [tex]x[/tex], will yield the same function value.

Conversely, to shift a function on a cartesian plane to the right by [tex]a[/tex] units, subtract [tex]a[/tex] from its independent variable.

For example, [tex]G(x+1)[/tex] is [tex]1[/tex] unit to the left of [tex]G(x)[/tex]. Conversely, [tex]G(x-1)[/tex] is [tex]1[/tex] unit to the right of [tex]G(x)[/tex]. The new function is to the left of [tex]G(x)[/tex]. Meaning that [tex]F(x)[/tex] should should add [tex]1[/tex] to (rather than subtract [tex]1[/tex] from) the independent variable of [tex]G(x)[/tex]. That rules out choice B) and D).

Multiplying a function by a number that is greater than one will stretch its graph vertically. Multiplying a function by a number that is between zero and one will compress its graph vertically.Multiplying a function by a number that is between [tex]-1[/tex] and zero will flip its graph about the [tex]x[/tex]-axis. Doing so will also compress the graph vertically.Multiplying a function by a number that is less than [tex]-1[/tex] will flip its graph about the [tex]x[/tex]-axis. Doing so will also stretch the graph vertically.

The graph of [tex]G(x)[/tex] is stretched vertically. However, similarly to the graph of this graph [tex]G(x)[/tex], the graph of [tex]F(x)[/tex] increases as [tex]x[/tex] increases. In other words, the graph of [tex]G(x)[/tex] isn't flipped about the [tex]x[/tex]-axis. [tex]G(x)[/tex] should have been multiplied by a number that is greater than one. That rules out choice C) and D).

Overall, only choice A) meets the requirements.

Since the plot in the question also came with a couple of gridlines, see if the points [tex](x, y)[/tex]'s that are on the graph of [tex]F(x)[/tex] fit into the expression [tex]y = F(x) = 3\sqrt{x - 1}[/tex].

Answer:

f(x) =3 sqrt(x+1)

Step-by-step explanation:

We notice two things about the graph, it has a shift to the left and is steeper

First the shift to the left

f(x) = g(x + C)  

C > 0 moves it left

C < 0 moves it right

g(x) is 0 at x=0   f(x) is 0 at  x=-1

We are moving it 1 unit to the left

This means our "c" is 1

f(x) = sqrt( x+1)

Now we need to deal with the graph getting steeper

f(x) = Cg(x)  

C > 1 stretches it in the y-direction

0 < C < 1 compresses it

Since it is getting taller, "c" must be greater than 1

Remember the - sign means it is a reflection across the x axis, which we do not have

f(x) =3 sqrt(x+1)

For angles other than 1st-quadrant angles, it can sometimes be difficult to identify the relevant sides of the relevant triangle.

Step-by-step explanation:

When the points designating each triangle are considered in order, they are seen to be in clockwise order. Segment FG is oriented to the west, while corresponding segment VW is oriented to the east. This means the figure could have been rotated 180° or reflected across a point. Either way, some translation may be necessary to align the figures as shown.

Possible transformations include ...

reflection across a point, then translation (depending on the location of the point)rotation 180° about a point, then translation (depending on the location of the point)

___

If one of the triangles is reflected across the midpoint of GW, it will coincide with the other triangle. Hence only one reflection across a chosen point is required.

A shipping company must design a closed rectangular shipping crate with a square base. The volume is 3072ft3. The material for the top and sides costs $4 per square foot and the material for the bottom costs $2 per square foot. Find the dimensions of the crate that will minimize the total cost of material.

Answers

The dimensions that minimize the total cost of material for the shipping crate are:

- Length: 24 feet

- Width: 24 feet

- Height: 8 feet

To solve this problem, we can start by writing down the volume formula for a rectangular box with a square base:

Volume = Length × Width × Height

Given that the volume is 3072 ft³, we have:

3072 = L × W × H

We also know that the material for the top and sides costs $4 per square foot and the material for the bottom costs $2 per square foot. Let's denote the areas of the top, bottom, and sides as A_top, A_bottom, and A_sides, respectively.

A_top = L × W

A_bottom = L × W

A_sides = 2 × (L × H + W × H)

The total cost, C, can be expressed as:

C = 4 × (A_top + A_bottom) + 2 × A_sides

C = 4 × (L × W + L × W) + 2 × 2 × (L × H + W × H)

C = 8LW + 4LH + 4WH

We can substitute the volume equation into the cost equation to eliminate one variable. Let's express L in terms of W and H from the volume equation:

L = 3072 ÷ (W × H)

Now substitute L into the cost equation:

C = 8(3072 ÷ (WH))W + 4(3072 ÷ (WH))H + 4WH

C = 24576 ÷ H + 12288 ÷ W + 4WH

To minimize C, we take the derivative with respect to W and H, set them equal to zero, and solve for W and H:

∂C/∂W = -12288/W² + 4H = 0

∂C/∂H = -24576/H² + 4W = 0

Solving these equations gives us W = 24 and H = 8, which leads to L = 3072 ÷ (24 × 8) = 16.

So, the dimensions that minimize the total cost of material are Length: 24 feet, Width: 24 feet, and Height: 8 feet.

the smallest value of possible to obtain a k-coloring.

Final answer:

The chromatic number for a map is the minimum number of colors needed to color the regions of the map such that no two adjacent regions have the same color.

Explanation:

The chromatic number for a map is the minimum number of colors needed to color the regions of the map such that no two adjacent regions have the same color.

The chromatic number can vary depending on the specific map and its regions. To determine the chromatic number, one approach is to use a graph-theoretic representation of the map, where each region corresponds to a vertex and adjacent regions are connected by edges. Then, a graph coloring algorithm can be used to find the minimum number of colors needed to properly color the regions of the map.

I need to mix brown paint using red, blue, and, yellow in the ratio of 2:1:3. If I need to mix 18 fluid ounces of paint, hwo much yellow paint will I need?

Answers

hihi! so the ratio 2:1:3 can be rewritten as 2/6 (red) 1/6 (blue) and 3/6 (yellow).

this is because you have 2 floz of red, 1 floz of blue, and 3 floz of yellow, which adds up to 6 floz of paint total in your ratio.

since you have 18 fl. oz. of paint, you multiply the ratio 3/6 by 18 to get 9 fl. oz. of yellow paint.

hope this helps!

There would be of 9 ounces yellow paint needed.

What is ratio?

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

The total quantity of fluid of paint= 18 ounces,

And the ratio of red, blue and yellow paint = 2:1:3

Let the multiplying factor in ratio is x,

So, total paint will be 6x,

According to given condition,

6x = 18 ounces,

x = 3 ounces

Since yellow paint is 3x,

So 3x = 9 ounces

9 ounces yellow paint is required,

[tex]2E=2.45-0.21\\\\\Rightarrow\ 2E=2.24\\\\\Rightarrow\ E=\dfrac{2.24}{2}=1.12[/tex]

Hence, the margin of error is 1.12 .

Final answer:

The margin of error can be calculated as half the width of the confidence interval.

Explanation:

The margin of error can be calculated by finding half the width of the confidence interval. In this case, the confidence interval is (0.21, 2.45), so the width is 2.45 - 0.21 = 2.24. Therefore, the margin of error is half of this width, which is 2.24/2 =

D.) (7, 0); the time it takes to fill up the water in the pool

Answers

Answer:

A).  (7, 0) The time it takes to empty the water in the  pool.

Step-by-step explanation:

If we extend the values we see that they are

x f(x)

5 10

5 5

7 0

So at time 7 minutes the pool is empty.

Answer:

(7, 0); the time it takes to empty the water in the pool

Step-by-step explanation:

The following table shows the amount of water leaking from an inflatable pool as a function of time:

x (time in minutes)    f(x)

0                            35

1                            30

2                            25

3                            20

4                             15

f(x) represents the amount of water in the pool. x intercept is the point where f(x) is 0 .At x intercept the amount of water in the pool is 0.

WE need to find out the point where f(x) becomes 0

F(x) is decreasing by 5. LEts extend the table till we get f(x) becomes 0

Decrease f(x) by 5

x (time in minutes)    f(x)

3                            20

4                             15

5                                  15-5=10

6                                  10-5=5

7                                   5-5=0

When x=7, f(x)=0. (7,0) is the x intercept.

(7, 0); the time it takes to empty the water in the pool

Jorge has a credit card debt of $7,600.97. Jorge’s credit card has an APR of 23.99% and asks that Jorge makes a minimum payment of 3.5% of his balance. For Jorge’s current balance, what is the minimum payment he must make to the credit card company each month?

a.
$266.03

b.
$228.03

c.
$2,280.29

d.
$2,660.34


If Jorge (from #6) pays the minimum payment each month how many months will it take Jorge to pay off his balance, assuming he doesn’t make any more charges to his credit card? Assume the card compounds monthly. You may want to use the TVM solver

a.
About 43 months

b.
About 23 months

c.
About 29 months

d.
About 30 months

Answers

Answer:

  a.  $266.03   a.  About 43 months

Step-by-step explanation:

1.  The calculation for the minimum payment is ...

  0.035 × $7600.97 = $266.03

__

2. The answer choices assume that Jorge makes a payment of $266.03 each month. After the first month, the minimum payment due is less than that amount. If Jorge only pays the minimum payment each month the balance will decrease by about 1.5% each month, and it will take about 31 years before the minimum payment is below $1.

The TVM Solver says it will be about 43 months for the card to be paid off if Jorge pays $266.03 each month.

Last year, 150 cases were reported of a new infectious disease. It has been predicted that the number will double every year. How many cases will be reported in the ninth year?

Answers

Answer:

76800 cases

Step-by-step explanation:

The number of cases of new infectious diseases reported last year= 150 cases

Number of cases are going to be double every year

Number of the cases in next or first year=150+150=300

Number of the cases in next or second year=300+300=600

Number of the cases in next or third year=600+600=1200

Number of the cases in next or fourth year=1200+1200=2400

Number of the cases in next or fifth year=2400+2400=4800

Number of the cases in next or sixth year=4800+4800=9600

Number of the cases in next or seventh year=9600+9600=19200

Number of the cases in next or eight year=19200+19200=38400

Number of the cases in next or ninth year=38400+38400=76800

Answers

Answer:

  1/2sin(6x) + 1/2sin(2x)

Step-by-step explanation:

You can look up the formulas for the product identities for sine and cosine, or you can guess and check using a graphing calculator. I did the calculator solution first (see the first attachment), then looked up the identities so I can tell you what they are (see the second attachment).

__

These identities are based on the sum and difference angle identities:

  sin(α+β) +sin(α-β) = (sin(α)cos(β) +sin(β)cos(α)) + (sin(α)cos(β) -sin(β)cos(α))

  = 2sin(α)cos(β)

Dividing by 2 gives the identity of interest in this problem:

  sin(4x)cos(2x) = (1/2)(sin(4x +2x) +sin(4x -2x))

  sin(4x)cos(2x) = (1/2)(sin(6x) +sin(2x))

What is the quadratic function that is created with roots -10 and -4 and a vertex at (-7, -9)?

Answers

Answer:

In vertex form it's [tex]y=(x+7)^2-9[/tex]

In standard form it's [tex]y=x^2+14x+40[/tex]

Step-by-step explanation:

We can use the vertex form to solve for a in

[tex]y=a(x-h)^2+k[/tex]

"a" is the number out front that dictates the steepness, or lack thereof, in a parabola.  That means that we need h and k (which we have in the vertex) and we need x and y (which we have in the form of one of the zeros).  Filling in using a vertex of (-7, -9) and a coordinate point (-7, 0):

[tex]0=a(-4-(-7))^2-9[/tex] simplifies a bit to

[tex]0=a(-4+7)^2-9[/tex] simplifies a bit more to

[tex]0=a(3)^2-9[/tex] and

[tex]0=a(9)-9[/tex] so

[tex]0=9a-9[/tex],

[tex]9=9a[/tex] and finally,

a = 1

Phew!  So there is the a value.  Now we can simply fill in the formula completely, using the vertex as our guide:

[tex]y=(x+7)^2-9[/tex]

In standard ofrm that is

[tex]y=x^2+14x+40[/tex]

We can check ourselves for accuracy by factoring that standard polynomial using whatever method of factoring you like for quadratics and get that the roots are in fact x = -10, -4

The only reason we needed the zeros is to use one of them as the x and y to solve for a.
