Final answer:

The maximum value of the quadratic function y = -2x^2 - 16x - 29 is 3, occurring at x = -4, found by determining the vertex of the parabola, which opens downwards due to the negative coefficient of the x^2 term.

Explanation:

To find the maximum or minimum value of the quadratic function y = -2x² - 16x - 29, we can utilize the properties of parabolas. Since the coefficient of the x² term is negative, the parabola opens downwards, meaning the vertex will give us the maximum value. The vertex of a parabola given by y = ax² + bx + c is found at the x-coordinate x = -b/(2a). Substituting the values from the given equation:

x = -(-16)/(2*(-2)) = -16/(-4) = -4

Now, we substitute this value back into the original equation to find the y-coordinate of the vertex:

y = -2(-4)² - 16(-4) - 29

y = -2(16) - 64 - 29

y = -32 + 64 - 29

y =3

Therefore, the maximum value of the function is 3, and it occurs at x = -4.

The answers for the given questions are:

(a) Order of popularity: Goron, Zora, Hylian,Gerudo, Other.

(b) Number of people voting for Goron: 89

(c) The estimate was not accurate.

(a) The popularity of the choices from greatest to least is:

1. Goron

2. Zora

3. Hylian

4. Gerudo

5. Other

(b) To find out how many people would have voted for Goron if 280 people voted in total, we first need to determine the proportion of votes Goron received in the primary election.

Total votes cast in the primary election = Sum of votes for all choices

= Goron + Zora + Hylian + Gerudo + Other

= 100 + 75 + 60 + 40 + 40

= 315 votes

Proportion of votes for Goron = (Votes for Goron / Total votes cast) * 100%

= (100 / 315) * 100%

≈ 31.75%

Now, to find out how many people would have voted for Goron out of the estimated 280 people:

Number of people voting for Goron = (Proportion of votes for Goron / 100%) * Estimated total voters

= (31.75 / 100) * 280

≈ 89 people

(c) The estimate of total voters from Part (b) was not accurate. The estimate was based on the assumption that all choices would receive votes in the same proportion as they did in the primary election. However, in reality, the number of votes for "Other" was higher than expected, indicating that the actual total number of voters might be higher than the estimated 280. Therefore, the estimate was not accurate.

Complete question:

The results of the primary election are shown. (a) Order the popularity of the choices from greatest to least. (b) It was estimated that 280 people were going to vote. If this was true, how many people would have voted for Goron? Show your work. (c) 40 people voted for “Other.” Was the estimate of total voters from Part (b) accurate? Explain.

B is the correct answer

Answer:f(x) = 8x + -4

Multiply f * x

fx = 8x + -4

Reorder the terms:

fx = -4 + 8x

Solving

fx = -4 + 8x

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by 'x'.

f = -4x-1 + 8

Simplifying

f = -4x-1 + 8

Reorder the terms:

f = 8 + -4x-1

Answer:

3/x + 2/(x+1) = 3/5x

[3 · 5(x + 1) + 2 · 5x] / 5x(x + 1) = 3(x + 1) / 5x(x + 1)

3 · 5(x + 1) + 2 · 5x = 3(x + 1)

15x + 15 + 10x = 3x + 3

15x + 10x - 3x = -15 + 3

22x = -12

Answer:

√245 or 15.65247...

Step-by-step explanation:

a² + b² = c²

14² + 7² = c²

196 + 49 = c²

245 = c²

√245 ≈ c

When you have a right triangle, you can use the Pythagorean Theorem to find the missing side length. (but it only works for RIGHT triangles)

Pythagorean Theorem:

a² + b² = c²         Since you know a=14 and b=7, plug it into the equation

(14)² + (7)² = c²

196 + 49 = c²

245 = c²

√245 = c    or 15.6524758425 = c

Answer:

B. 90 + 90 √2

Step-by-step explanation:

From first base to the second base, it will travel 90 feet.

From the second base to the home plate, it will travel a longer distance.  How much?  Well, if you look at the layout of the field, you'll see that if you draw a line from second base to the home plate, you'll form two rectangular triangles, one with the 1st base, another one with the 3rd base.

The line from the 2nd base to home plate is the hypotenuse, which we can easily find by:

h²=90² + 90²

h = √(2 * 90²)

h = 90 √2

So, from second base to home plate, the ball has traveled 90 √2

Overall: 90 + 90 √2

Step-by-step explanation:

Odd numbers are any numbers that end with 1, 3, 5, 7, 9.

Out of the numbers inbetween 75 & 100, the odd numbers are:

75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99,

which makes 13.

Set the amount of numbers you got over the total amount.

13/27

You have a 13/27, or 48.15% chance of picking an odd number.

~

The numbers you are looking for are 23, 25, and 27. Let's start by defining a variable.  Let x be the first of the three odd numbers.  Since odd numbers are 2 apart, that means that the other two numbers are x + 2 and x + 4.

Now, their sum is x + (x + 2) + (x + 4) which equals 3x + 6.

Decrease that by the second number, x + 2.  That means:  3x + 6 - (x + 2), which is equal to 2x + 4.

So now we know that 2x + 4 = 50, and we can solve that easily:

2x + 4 = 50

2x = 46

x = 23

Therefore, the three odd numbers are 23, 25, and 27. Hope this helps! Please mark Brainliest. Thank you v much! :)

The answer to the problem is the three consecutive odd integers 23, 25, and 27.

Let's solve the problem step by step. We are looking for three consecutive odd integers. A useful way to express consecutive odd integers algebraically is as x, x+2, and x+4, where x is any odd integer.

The problem states that the sum of these integers minus the second one equals 50. This provides the equation: x + (x+2) + (x+4) - (x+2) = 50. Simplifying this equation, we get 2x + 4 = 50. We can further simplify to find that x = 23.

So, the three consecutive odd integers are 23, 25, and 27.

C  1055 04 cm

Step-by-step explanation:

We don't need to see the figure, since we know for sure the cone fits into the cylinder (smaller diameter and height).

So, we first need to calculate the volume of the cylinder, which is given by the formula:

VT = π * r² * h

VT = 3.14 * 5² * 16 = 3.14 * 400 = 1,256 cubic cm

Then we calculate the volume of the cone, which is given by:

VC = (π * r² * h)/3

VC = (3.14 * 4² * 12)/3 = (3.14 * 192)/3 = 200.96 cu cm

Then we calculate the void space left inside the cylinder by subtracting the volume of the cone from the volume of the cylinder:

NV = VT - VC = 1,256 - 200.96 = 1,055.04 cu cm

The correct answers are: C. Angle 4 F. Angle 6 In mathematics, exterior angles are formed outside between any side of a shape and a line extended from the next side.

The correct answer is option C and F.

In a triangle, the sum of the measures of the interior angles is always 180 degrees. Since angles 5, 3, and 1 are interior angles, their sum is 180 degrees.

The sum of the measures of the exterior angles of a triangle is always 360 degrees. Therefore, the sum of exterior angles 4, 6, and 2 is also 360 degrees.

Now, to determine the individual measures of the exterior angles, we know that the sum of the measures of the linear pairs (an exterior angle and its adjacent interior angle) is 180 degrees.

Therefore, angle 4 is an exterior angle since it forms a linear pair with angle 1.

Similarly, angle 6 is an exterior angle since it forms a linear pair with angle 3.

Angle 2 is not an exterior angle since it does not form a linear pair with any other angle in the given triangle.

So, the correct answers are:

C. Angle 4

F. Angle 6
