Answer:

Option D) h(x), f(x), g(x)

Step-by-step explanation:

we know that

The axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex of the parabola

Part 1) we have

[tex]f(x)=4x^{2} -1[/tex]

This is a vertical parabola open upward

The vertex is a minimum The vertex is the point (0,-1)

The x-coordinate of the vertex is 0

so

The axis of symmetry is x=0

Part 2) we have

[tex]g(x)=x^{2}-8x+5[/tex]

This is a vertical parabola open upward

The vertex is a minimum

Convert the equation into vertex form

[tex]g(x)-5=x^{2}-8x[/tex]

[tex]g(x)-5+16=x^{2}-8x+16[/tex]

[tex]g(x)+11=x^{2}-8x+16[/tex]

[tex]g(x)+11=(x-4)^{2}[/tex]

[tex]g(x)=(x-4)^{2}-11[/tex]

The vertex is the point (4,-11)

The x-coordinate of the vertex is 4

so

The axis of symmetry is x=4

Part 3) we have

[tex]h(x)=-3x^{2}-12x+1[/tex]

This is a vertical parabola open downward

The vertex is a maximum

Convert the equation into vertex form

[tex]h(x)-1=-3x^{2}-12x[/tex]

[tex]h(x)-1=-3(x^{2}+4x)[/tex]

[tex]h(x)-1-12=-3(x^{2}+4x+4)[/tex]

[tex]h(x)-13=-3(x+2)^{2}[/tex]

[tex]h(x)=-3(x+2)^{2}+13[/tex]

The vertex is the point (-2,13)

The x-coordinate of the vertex is -2

so

The axis of symmetry is x=-2

Part 4) Rank their axis of symmetry from least to greatest

1) h(x) -----> axis of symmetry -2

2) f(x) -----> axis of symmetry 0

3) g(x) -----> axis of symmetry 4

so

h(x),f(x),g(x)

Answer: Hence, there are 36 total number of invited guests.

Step-by-step explanation:

Let the total number of invited guests be 'x'

Part of those invited had already arrived = [tex]\dfrac{2}{3}x[/tex]

Number of people just arrived = 6

According to question, it brings the number at the party to [tex]\dfrac{5}{6}[/tex] of those invited.

So, it becomes,

[tex]\dfrac{2}{3}x+6=\dfrac{5}{6}x\\\\6=\dfrac{5}{6}x-\dfrac{2}{3}x\\\\6=\dfrac{5x-4x}{6}\\\\6=\dfrac{x}{6}\\\\x=6\times 6\\\\x=36[/tex]

Hence, there are 36 total number of invited guests.

Answer:

42 People

Step-by-step explanation:

P is the total amount of people. Before Cedric arrived, there were (2/3)P people at the party. After Cedric and six other people arrived, there are (2/3)P+7 people at the party. Since this is the same as (5/6)P, we solve (2/3)P+7=(5/6)P to find that P=42.

Answer:

the function is odd

Step-by-step explanation:

A function f(x) is said to be even if f(-x) = f(x)

On the other hand, f(x) is said to be odd if f(-x)≠ f(x).

We plug in -x in place of x in the given function and simplify;

f(-x) = 3(-x-1)^4

f(-x) = 3[-1(x+1)]^4

f(-x) = 3 *(-1)^4 * (x+1)^4

f(-x) = 3(x+1)^4 ≠ f(x)

Therefore, the function given is odd

Answer:

The given function is odd

Step-by-step explanation:

we need to determine the function [tex]f(x)=3(x-1)^{4}[/tex] is odd or even

Since, A function f(x) is said to be even if [tex]f(-x) = f(x)[/tex]

and f(x) is said to be odd if [tex]f(-x)= - f(x)[/tex] and [tex]f(-x) \neq f(x)[/tex]

We Replace x with -x in the given function and solve;

[tex]f(x)=3(x-1)^{4}[/tex]

[tex]f(-x)=3(-x-1)^{4}[/tex]

take out the negative common,

[tex]f(-x)=3[-(x+1)]^{4}[/tex]

Since [tex](-1)^{4}=1[/tex]

[tex]f(-x)=3(x+1)^{4}[/tex]

[tex]f(-x) \neq f(x)[/tex]

Hence, the given function is odd

Answer:

[tex]y^2=\frac{1}{8}x[/tex]

Step-by-step explanation:

The focus lies on the x axis and the directrix is a vertical line through x = 2.  The parabola, by nature, wraps around the focus, or "forms" its shape about the focus.  That means that this is a "sideways" parabola, a "y^2" type instead of an "x^2" type.  The standard form for this type is

[tex](x-h)=4p(y-k)^2[/tex]

where h and k are the coordinates of the vertex and p is the distance from the vertex to either the focus or the directrix (that distance is the same; we only need to find one).  That means that the vertex has to be equidistant from the focus and the directrix.  If the focus is at x = -2 y = 0 and the directrix is at x = 2, midway between them is the origin (0, 0).  So h = 0 and k = 0.  p is the number of units from the vertex to the focus (or directrix).  That means that p=2.  We fill in our equation now with the info we have:

[tex](x-0)=4(2)(y-0)^2[/tex]

Simplify that a bit:

[tex]x=8y^2[/tex]

Solving for y^2:

[tex]y^2=\frac{1}{8}x[/tex]

Answer: x = -1/8y^2

Step-by-step explanation

Focus: (-2,0)

Directrix: x=2

Answer:

Yes, there will be enough root beer for everyone to have at least one cup

Step-by-step explanation:

step 1

Find the volume of the cylinder root beer keg

The volume is equal to

[tex]V=\pi r^{2} h[/tex]

we have

[tex]r=13/2=6.5\ in[/tex] -----> the radius is half the diameter

[tex]h=17\ in[/tex]

substitute

[tex]V=\pi (6.5)^{2} (17)[/tex]

[tex]V=718.25\pi\ in^{3}[/tex]

step 2

Find the volume of the cylinder cups

The volume is equal to

[tex]V=\pi r^{2} h[/tex]

we have

[tex]r=3/2=1.5\ in[/tex] -----> the radius is half the diameter

[tex]h=4\frac{3}{4}\ in=4.75\ in[/tex]

substitute

[tex]V=\pi (1.5)^{2} (4.75)[/tex]

[tex]V=10.6875\pi\ in^{3}[/tex]

step 3

Multiply the volume of one cup by 50 (the total number of students) and then compare the result with the volume of the cylinder root beer keg

so

[tex]10.6875\pi*(50)=534.375\pi\ in^{3}[/tex]

[tex]534.375\pi\ in^{3}< 718.25\pi\ in^{3} [/tex]

therefore

There will be enough root beer for everyone to have at least one cup

Answer:

Yes. There is enough for everyone.

Step 1: Find the volume of the keg

Diameter : 13

Radius : 6.5

Height : 17

Formula for the area of a circle (base) is πr^2

Solve that using the above formula.

Base area = 132.73

Multiply that by the height.

Keg volume : 2,256.45 inches cubed

Step 2: Find the volume of the cups

Diameter : 3

Radius : 1.5

Height : 4 3/4

Formula for area of a circle (base) is πr^2

Solve that using the above formula.

Base area = 7.07

Multiply that by the height.

Cup volume : 33.58 inches cubed

Step 3: Multiply cup volume by 50

33.58 x 50 = 1,678.79

Step 4: Check how much root beer you have for everyone.

Root beer needed : 2,256.45

Root beer available : 1,678.79

Is there enough root beer?

Yes

Answer:

cl   +   1/(N+1)

Step-by-step explanation:

If we assume that the Nth harmonic number is cl. Then we are assuming that 1+1/2+1/3+1/4+...+1/N=cl

And we know that the (N+1)th harmonic number can be found by doing

1+1/2+1/3+1/4+...+1/N+1/(N+1)

=cl    +   1/(N+1)

The (N+1)th harmonic number is cl   +   1/(N+1) given that the Nth term is cl

Other way to see the answers:

Maybe you want to write it as a single fraction so you have

[cl(N+1)+1]/(N+1)=[cl*N+cl+1]/(N+1)

The expression value is [tex]hn+(\frac{1}{n+1} )[/tex].

Assume that [tex]n[/tex] is an integer variable whose value is some positive integer [tex]N[/tex].

Assume also that [tex]hn[/tex] is a variable whose value is the [tex]N_{th} [/tex] harmonic number.

An expression whose value is the [tex](N+1)th[/tex] harmonic number is [tex]hn+(\frac{1}{n+1} )[/tex].

x = - 10

Step-by-step explanation:

Answer:

x > 1/6

Step-by-step explanation:

Perform the indicated multiplication.  Then:

-16x + 8 < 2x + 5

Combining the x terms, we get:

8 < 18x + 5.

Simplifying further, we get:

3 < 18x, so that   3/18 < x, or x > 1/6

Answer:

We only need one simple theorem for this.

Theorem 7 - The Exterior Angle Theorem: An exterior angle of a triangle is equal to the sum of the two remote interior angles.

So in this case, the measurement of the exterior angle is (45x)°, and the interior angles are (25x)° and (57 + x)°.

=> Therefore, we have:

25x + (57 + x) = 45x

25x + x - 45x  = - 57

-19x                 = -57

x                      = -57/(-19) = 3

So x = 3

Outside angle = addition of the two inner angles.

45x = 25x + 57 + x

45x = 26x + 57

45x - 26x = 57

19x = 57

x = 57/19

x = 3

Final answer:

Two teams working together will take approximately 133.33 hours or about 5.56 days to clean the city streets. This is less than the one week (7 days) available before filming begins, so the streets will be clean in time.

Explanation:

To calculate how long it will take for two teams working together to clean the city streets, we use the concept of combined work rates.

The first team requires 200 hours to clean the streets, while the second team requires 400 hours.

When working together, we can add their rates of work, which means the first team cleans 1/200 of the city per hour, and the second team cleans 1/400 of the city per hour.

The combined rate of work will be:
1/200 (team A's rate) + 1/400 (team B's rate)
= 2/400 + 1/400
= 3/400

So, together they clean 3/400 of the city per hour. To find out how many total hours it will take to clean the entire city, we take the reciprocal of their combined rate
1 / (3/400)
= 400/3
≈ 133.33 hours

Since there are 24 hours in a day, we divide the total hours by 24 to find out how many days it will take:
133.33 hours / 24 hours/day
≈ 5.56 days
Given that the crew will arrive in one week, which is 7 days, this is within the time frame required before filming begins. The teams have enough time to clean the streets before the cameras start rolling.

Hey there! Thanks for asking your question here on Brainly.

Let's split this question up into two parts: large and cold drink. Now that we have our two parts, we need to figure out which would be the numerator and which would be the denominator. Looking at the question, the size large would be the numerator because that is the part out of the whole we are finding. The whole would be cold drink because that is given, meaning that we are looking for the larges out of the entire cold drink section.

Now, we'll find the total amount of customers that ordered cold drinks for the whole part of our fraction. That is 25 customers. Next, we set the numerator of our fraction to the amount of customers that ordered large, cold drinks. Therefore, our fraction would be 5/25. The fraction in decimal form is 0.2, and in percent form is 20%.

Therefore, the probability that a customer ordered a large given that he or she ordered a cold drink is 20%.

Hope this helps! If there is anything else that I can help you with, please let me know! :)

After calculating the monthly costs for Emily's usage, Company A would cost $400 while Company B would cost $230. Therefore, Company B is the better choice for Emily as it offers a lower total bill.

To determine which cell phone company, A or B, offers a better monthly plan for Emily who uses 400 texts, 90 minutes of talk, and 2.1 gigs of data per month, we need to calculate the total monthly costs for both companies.

Company A:

Company B:

After calculating the costs, it is clear that Company B offers a lower total bill despite the higher monthly flat fee. Hence, Emily should choose Company B because the total bill will be lower.

Answer:

Value of cos B is B)12/13

The value of cos B in triangle ΔABC cannot be definitively determined without additional information such as side lengths. However, assuming a right triangle configuration with an adjacent side of length 12 and a hypotenuse of length 13, the cos B could be calculated as 12/13.

In the triangle ΔABC, the value of cos B can be calculated if we know the measures of the sides of the triangle. Without the values of the sides, we can't give an exact value for cos B. However, from the given options, we would assume that the triangle is a right-triangle, and B is the angle formed by the adjacent side of length 12 and the hypotenuse of length 13. Thus, the value of cos B would be equal to the adjacent side (b) divided by the hypotenuse (c), which matches option B) 12/13.

Remember that in a right triangle:
The cosine of an angle (cos B) is defined as the ratio of the length of the adjacent side to the length of the hypotenuse. This formula, cos B = b/c is a direct application of the Pythagorean theorem.

Step-by-step explanation:

THE GIVEN EXPRESSION IS

[tex]\sqrt[3]{\frac{1}{1000c^{9}d^{12} } }[/tex]

To simplify this expression, we just have to apply the cubic root to each part of the fraction, as follows

[tex]\frac{\sqrt[3]{1} }{\sqrt[3]{1000c^{9} d^{12} } }[/tex]

Then, we solve each root. Remember that to solve roots of powers, we just need to divide the exponent of the power by the index of the root, as follows

[tex]\frac{1}{10c^{\frac{9}{3} } d^{\frac{12}{3} } }[/tex]

Therefore, the equivalent expression is
