row 4 answer 6 i just took the quiz

Using an inverse rule of three, it is found that Bobby needs to call 18 more people.

This question is solved by proportions, applying a rule of three.The number of people working and the time needed to complete the work are inversely proportional, as more people means less time, thus, instead of cross multiplication, we multiply the lines, which is an inverse rule of three.When Bobby's parents call, with 9 people, they will need 6 hours to finish the job. How many people are needed to finish the job in 2 hours?

The rule of three is:

9 people - 6 hours

x people - 2 hours.

Multiplying by line:

2x  =  6  x  9

x   =   3  x   9

x    =  27

Already has 9 people, in total needs 97, so he needs to call 27 - 9 = 18 more people.

Draw a perpendicular at x=2

Now reflect each coordinates across there

(2,2)

(8,4)

New coordinate (-6,4)

(6,8)

New coordinate

Answer:

Rule:  Reflect the figure across the y-axis then translate the reflected figure 4 units to the right.

Step-by-step explanation:

Points of Figure A:

(2, 2)

(8, 4)

(6, 8)

Draw a line at x = 2, then reflect each point across the line

(2, 2) → (2, 2)

(8, 4) → (-4, 4)

(6, 8) → (-2, 8)

Reflection in the y-axis:  (x, y) → (-x, y)

As the y-values of our two figures have not changed, the first part of the rule is: reflect across the y-axis

If we reflect the figure across the y-axis, the points of the reflected figure are:

(-2, 2)

(-8, 4)

(-6, 8)

To bring the reflected figure back to where we want it (reflection in x = 2) we need to translate the figure 4 units to the right:

(-2 + 4, 2) = (2, 2)

(-8 + 4, 4) = (-4, 2)

(-6 + 4, 8) = (-2, 8)

So the final rule is:

Reflect the figure across the y-axis then translate the reflected figure 4 units to the right.

I’m pretty sure I had the question before

The probability that Joseph, Heidi, and Katy are chosen is 1/40 if three of the ten people in the Latin club are chosen at random to represent the club at a tournament option (G) is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

Total ways of choosing 3 out of 10 = C(10, 3) = 120

Total outcomes = 120

Total favorable outcomes = 3(Joseph, Heidi, and Katy)

Probability = 3/120 = 1/40

Thus, the probability that Joseph, Heidi, and Katy are chosen is 1/40 if three of the ten people in the Latin club are chosen at random to represent the club at a tournament option (G) is correct.

The maximum height reached by the object is 12.5 feet.

The vertex of a parabola is the point where the curve changes direction, and is located at the minimum or maximum point of the quadratic equation. If the coefficient of the x² term is positive, the parabola opens upwards and the vertex represents a minimum value. If the coefficient is negative, the parabola opens downwards and the vertex represents a maximum value.

To find the maximum height reached by the object, we need to find the vertex of the parabola.

The x-coordinate of the vertex can be found using the formula x = -b/2a, where a is the coefficient of the x² term, and b is the coefficient of the x term in the quadratic equation that represents the parabola.

In this case, the equation is of the form y = ax² + bx + c, where y is the height and x is the time. Using the given coordinates, we can set up a system of equations to solve for a, b, and c:

0 = a(1)² + b(1) + c

16 = a(5)² + b(5) + c

0 = a(9)² + b(9) + c

Simplifying each equation, we get:

a + b + c = 0

25a + 5b + c = 16

81a + 9b + c = 0

Solving for c in the first equation, we get c = -a - b. Substituting this into the other two equations, we get:

25a + 5b - a - b = 16

81a + 9b - a - b = 0

Simplifying these equations, we get:

24a + 4b = 16

80a + 8b = 0

Solving for b in the second equation, we get b = -10a. Substituting this into the first equation, we get:

24a + 4(-10a) = 16

4a = 2

a = 1/2

Substituting this value of a into the equation b = -10a, we get b = -5. Finally, substituting a, b, and c = -a - b into the equation for the x-coordinate of the vertex, we get:

x = -b/2a = 5

So the maximum height is achieved at time x = 5, which corresponds to a height of:

y = ax² + bx + c = (1/2)(5)² - 5(5) = -12.5

However, we are looking for the maximum height, so we take the absolute value of this result, which gives:

|y| = 12.5

Therefore, the maximum height reached by the object is 12.5 feet.

Answer:

11 and -11

Step-by-step explanation:

This problem can really only be solved either by way of a calculator or simple memorization. In this case, the product (121) is a perfect square root, meaning it has a whole number answer. One square root of 121 is 11. The second square root of 121 is -11.

[tex]\sqrt{121} = 11[/tex]

[tex]\sqrt{121} = -11[/tex]

You can check your work by squaring your answer and seeing whether it equals the product. Remember, a negative number times another negative number results in a positive answer.

[tex]11^{2} = 121[/tex]

[tex]-11^{2} = 121[/tex]

The two square roots of the number 121 are 11 and -11.

The square root of a number is a value that, when multiplied by itself, gives the original number.

In the case of 121, the square root represents the number that, when multiplied by itself, equals 121.

The two square roots of 121 are 11 and -11 because both 11 and -11, when squared, result in 121.

When we calculate 11 × 11, we get 121.

So, 11 is one of the square roots of 121.

Similarly, when we calculate (-11) × (-11), we also get 121. So, -11 is also a square root of 121.

Therefore, the two square roots of 121 are 11 and -11.
