The equation of the line of symmetry of the parabola y = x² + 16x + 64 will be x + 8 = 0.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient. Then the equation of the parabola will be given as,

y = a(x - h)² + k

The equation of the parabola is given below.

y = x² + 16x + 64

Convert the standard equation into a vertex form. Then we have

y = x² + 16x + 64

y = (x + 8)²

We know that the line of symmetry passes through the vertex of the parabola. Then the equation of the line of symmetry is given as,

x + 8 = 0

The equation of the line of symmetry of the parabola y = x² + 16x + 64 will be x + 8 = 0.

Answer:

The correct answer is 13

Step-by-step explanation:

Answer:

x = 8

y = 146

Error = 4.86%

Step-by-step explanation:

Number of business class passenger = x

and the economy class passenger = y

Total number of passengers = 154

x + y = 154 ------(1)

Cost of business class tickets and economy class tickets are €320 and €85 respectively.

Total amount received by airlines is €14970.

320x + 85y = 14970

64x + 17y = 2994 --------(2)

Multiply equation (1) by 17 and subtract from equation (2)

(64x + 17y) - (17x + 17y) = 2994 - 2618

47x = 376

x = 8

From equation (1),

8 + y = 154

y = 154 - 8

y = 146

Airline officer wrote down the amount received as €14270

Then difference from the actual amount received = 14970 - 14270

                                                                                   = €700

% Error =  [tex]\frac{\text{Difference in amount}}{\text{Actual amount}}\times 100[/tex]

            = [tex]\frac{700}{14970}\times 100[/tex]

            = 4.676

            ≈ 4.68%

Therefore, x = 8 and y = 146

             and % error = 4.68%

Answer:

Option D: 159 3/8 cm^3

Step-by-step explanation:

1. Let us rewrite the dimensions, and the options to make this a little more clear ~ (dimensions) 5 cm, 8 1/2 cm, 3 3/4 cm ⇒ (options) 17 1/4 cm^3, 18 3/4 cm^3, 27 1/4 cm^3, and 159 3/8 cm^3

2. To find the volume of most 3-dimensional figures, you would have to multiply the Base * height, so for a rectagular prism ⇒ Base * height = length * width * height

3. Substitute and compute the volume through algebra:

5 cm * 8 1/2 cm * 3 3/4 cm =

5 cm * 17/2 cm * 15/4 cm =

85/2 cm^2 * 15/4 cm =

1275/8 cm^3 =

159 3/8 cm^3

4. This means that the Volume of the Rectangular Prism = 159 3/8 cm^3 (Option D)

The volume of the rectangular prism is 159/8 cm³.

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

To find the volume of a rectangular prism, we multiply the length, width, and height.

The length of the prism is 5 cm, the height is 8 and one-half cm (or 17/2 cm), and the width is 3 and three-fourths cm (or 15/4 cm).

So, the volume is:

V = l × w × h

V = 5 cm × 15/4 cm × 17/2 cm

V = 159/8 cm³

Therefore, the volume of the rectangular prism is 159/8 cm³.

Preventing identity theft involves securing personal items like credit cards and wallets, using strong passwords, monitoring credit history, and being cautious when sharing personal information, especially during job searches or online interactions.

Best Practices to Prevent Identity Theft

Identity theft, or 'True-name Fraud,' is a significant threat where criminals use stolen personal information to commit fraud. Protecting oneself from identity theft involves a number of crucial steps:

a.

The polynomial w^2+18w+84 cannot be factored

The perfect square trinomial is w^2+18w + 81

----------

The reason the original can't be factored is that solving w^2+18w+84=0 leads to no real solutions. Use the quadratic formula to see this. The graph of y = x^2+18x+84 shows there are no x intercepts. A solution and an x intercept are basically the same. The x intercept visually represents the solution.

w^2+18w+81 factors to (w+9)^2 which is the same as (w+9)(w+9). We can note that w^2+18w+81 is in the form a^2+2ab+b^2 with a = w and b = 9

================================================

b.

The polynomial y^2-10y+23 cannot be factored

The perfect square trinomial is y^2-10y + 25

---------

Using the quadratic formula, y^2-10y+23 = 0 has no rational solutions. The two irrational solutions mean that we can't factor over the rationals. Put another way, there are no two whole numbers such that they multiply to 23 and add to -10 at the same time.

If we want to complete the square for y^2-10y, we take half of the -10 to get -5, then square this to get 25. Therefore, y^2-10y+25 is a perfect square and it factors to (y-5)^2 or (y-5)(y-5)

Answer:

No slant asymptote.

Step-by-step explanation:

No it hasn't .

If we do the division we find the quotient is a trinomial in x^2 so not a straight line, so there is no slant asymptote.

The one asymptote is the vertical line x = 3, because when x = 3 the denominator becomes 0.

Final answer:

To find the slant asymptote for the given function f(x), perform long division of the numerator by the denominator. The result is a quadratic function, which is the equation of the slant asymptote, specifically y = x^2 - x - 3.

Explanation:

The function f(x) = (x^3 - 4x^2 + 2x - 6)/(x - 3) does indeed have a slant asymptote, since the degree of the numerator is exactly one more than the degree of the denominator. To find the equation of the slant asymptote, you may perform polynomial long division or synthetic division. You would divide x^3 - 4x^2 + 2x - 6 by x - 3 to obtain the quotient which will be the equation of the slant asymptote.

When you do that, you'll find that the quotient is x^2 - x - 3. Since there's no remainder, or the remainder is of lesser degree than the denominator, the function approaches the line y = x^2 - x - 3 as x approaches infinity or negative infinity. This quadratic function is the slant asymptote for f(x).

Answer:

D

Step-by-step explanation:

On the graph, the first action you see is a straight line going up. The key word you look for in the word explanations are "increase" and "constant rate". Then, the 2nd action you see is a straight line not going up or down, just staying on the same level. This could be called "remaining the same" or stopping/resting. Then, you see a straight line going down. You look for "decrease" at a "constant rate." D matches all of those.

The domain of a function is the set of input values where function defines thus the domain will be all real numbers so option (A) is correct.

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

As per the given graph,

The function is continuous at every interval of x so the domain will be negative infinity to positive infinite or all real numbers.

Hence "The domain of a function is the set of input values where function defines thus the domain will be all real numbers".

315 students would answer "yes". If 42 out of 50 students answered yes, that'd be 84% (you can determine this by dividing 42/50). Once you've determined that part,  you can multiply 375 by 0.84 (converting a percentage to a decimal), which would give you 315.

Please mark brainliest if this helped in any way, thank you! Have a great day! :)

Out of 50 surveyed students, 84% answered 'yes' to the question about starting a recycling program. Applying this percentage to the whole school of 375 students, we estimate that about 315 would say 'yes'. So, the correct choice is C. 315.

To answer this question, we first need to find out what fraction of students surveyed answered 'yes'. In this case, it's 42 out of 50 students, or 84%. If we apply this percentage to the entire school population, we can estimate how many of the 375 students would likely answer 'yes'.

To do this, you multiply the total number of students (375) by the percentage that answered 'yes' (.84 or 84%) which would give us 315.

So, out of 375 students, we can estimate that approximately 315 would answer 'yes' to the question about starting a recycling program. Hence, the correct answer is C. 315.

Answer: 28.26 meters

Step-by-step explanation:

Hi, to answer this question we have to find the perimeter of the semicircle.

P = (2 π r ) /2 (perimeter of a circle divided by 2)

The length of AB is the diameter of the circle (18 meters)

Since

Diameter (d) = 2 radius (r)

Replacing with the value given:

18 =2r

18/2=r

9 =r

Back on the perimeter formula

P = (2 π r ) /2

Replacing with the values given

P = (2 x 3.14 x 9) /2

P = 28.26 meters
