Find the perimeter of the figure.

The most appropriate viewing range for the quadratic function is given as follows:

The quadratic function for this problem is defined as follows:

f(x) = x² - 11x + 18.

The function can be factored as follows:

f(x) = (x - 2)(x - 9).

Hence the roots are:

Meaning that the viewing range should include x = 2 and x = 9.

The coefficients of the function are:

a = 1, b = -11, c = 18.

Hence the x-coordinate of the vertex is of:

x = -b/2a

x = 11/2

x = 5.5.

Hence the minimum value of the function is the y-coordinate of the vertex, given as follows:

y = 5.5² - 11(5.5) + 18

y = -12.25.

Meaning that Ymin should be less than -12.25.

From the given trapezoid the value of the x is 1.

What is the trapezoid?

The sum of all the angles in a trapezoid is equal to 360°. The sum of the angles on the same side is equal to 180°.

We have,

Since a Trapizode has 360 Degrees total and since the sides are equal we can say that

180 = 66 + ∠R

∠R = 180 - 66

∠R = 114

so,

180 = 66 + (-2 + 116x)

180 = 66 - 2 + 116x

180 = 64 + 116x

180 - 64 = 116x

116 = 116x

x = 1

Therefore, from the given trapezoid the value of the x is 1.

Answer:

  1/(ab) if a ≠ 0, b ≠ 0, and (a+b) ≠ 0

Step-by-step explanation:

You want the simplified form of 1/(a²+ab) +1/(ab+b²) and any applicable conditions.

The expression is simplified by writing it over a common denominator and cancelling any common terms from numerator and denominator.

  [tex]\dfrac{1}{a^2+ab}+\dfrac{1}{ab+b^2}=\dfrac{1}{a^2+ab}\cdot\dfrac{b}{b}+\dfrac{1}{ab+b^2}\cdot\dfrac{a}{a}=\dfrac{b+a}{a^2b+ab^2}\\\\=\dfrac{a+b}{ab(a+b)}=\boxed{\dfrac{1}{ab}\quad a\ne0,b\ne0,(a+b)\ne0}[/tex]

Answer: 20% of 160 is 32.

Step-by-step explanation:

The percentage is from the word percent which means one part in a hundred. It is a part of the base or the whole determined by the rate. Usually, the percentage is smaller than the base. However, there are also cases where the percentage is greater than the base. This happens when the percent is greater than 100%.

To find the percentage, you have to multiply the base and the rate. The base is the 100% or original amount or the whole while the rate is the ratio of the percentage to the base and it has the percent sign (%). Remember that you have to convert the rate to a decimal number by moving the decimal point twice to the left.

Let us now find the 20% of 160.

20% = 0.2

percentage = 160 × 0.2

= 32

Step-by-step explanation:

To find the percent of the people who attended the Baybridge Middle School Winter Formal who are not students at Baybridge, we can use the following steps:

Find the fraction of non-student attendees: 18 attendees out of 90 total attendees can be represented as 18/90.

Convert the fraction to a decimal: 18/90 = 0.20, which can be rounded to 0.2.

Convert the decimal to a percentage: 0.2 * 100 = 20%.

So, 20% of the people who attended the Baybridge Middle School Winter Formal are not students at Baybridge.

The capacity of the trophy that us 30 cm high is 0.4286 liter

An equation is an expression that shows how numbers and variables are linked together using mathematical operations such as addition, subtraction, multiplication and division.

7 cm height cup holds 100 ml. Therefore:

7 cm = 100 ml

For a 30 cm height trophy:

30 cm = 30 cm * 100 ml per 7 cm = 428.57 ml

1000 ml = 1 l

Here is a step-by-step explanation of the independence of the pair of events of choosing a number between 1000 and 5000 and flipping a coin:

Understanding the definition of independent events: Independent events are events that have no influence on each other. The outcome of one event does not affect the outcome of the other.

Event 1: Choose a number between 1000 and 5000: This event involves randomly selecting a number within the specified range.

Event 2: Flip a coin: This event involves flipping a coin and observing whether it lands on heads or tails.

Check for influence: To determine whether the events are independent, we need to check if the outcome of one event affects the outcome of the other. In this case, the outcome of the coin flip has no effect on the number you choose, and your choice of number has no effect on the outcome of the coin flip.

Conclusion: Since the outcome of one event does not affect the outcome of the other, the pair of events of choosing a number between 1000 and 5000 and flipping a coin are considered independent.

So, the pair of events of choosing a number between 1000 and 5000 and flipping a coin are independent events.

The y-intercept of this quadratic function is 6.

The axis of symmetry of this quadratic function is 1.

The vertex of this quadratic function is (1, 5).

Mathematically, the axis of symmetry of a quadratic function can be calculated by using this mathematical expression:

Axis of symmetry, Xmax = -b/2a

Where:

a and b represents the coefficients of the first and second term in the quadratic function.

For the given quadratic function f(x) = x² - 2x + 6, we have:

Axis of symmetry, Xmax = -b/2a

Axis of symmetry, Xmax = -(-2)/2(1)

Axis of symmetry, Xmax = 2/2 = 1.

Vertex (h, k) = (1, 5).

In Mathematics, the y-intercept of any graph such as a quadratic function, generally occur at the point where the value of "x" is equal to zero (x = 0).

y-intercept = 6.

What is circumference?

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area. The length of a straight line drawn from the centre of a circle equals the diameter of that circle.

If you move along a full circle of a radius 'r', the distance covered by you is equal to [tex]2\pi r[/tex]

Part 1:

Given that, Jack's aeroplane travels in a circle of a cord of length 15ft for 5 times

The total distance travelled by plane is [tex]15*2\pi *15[/tex]

[tex]=150\pi[/tex]

= 471.239 ft

Part 2:

Given that, Jack flew his aeroplane 100 times with a cord of 50 ft.

The total distance covered by the plane is 100 * (2*50*[tex]\pi[/tex])

If he increases the length by 10 ft, The cord will now be 60 ft.

The total distance it would cover then is 100 * (2*60*[tex]\pi[/tex])

Now,

100 * (2*60*[tex]\pi[/tex]) - 100 * (2*50*[tex]\pi[/tex])

= 100 * (2*(60-50))*[tex]\pi[/tex])

= 100 * 2 * 10 * [tex]\pi[/tex]

Step-by-step explanation:

The sample standard deviation weight of the 50 candies is, 0.07 grams.

The amount of variation or dispersion in a set of data values is measured by standard deviation. A statistical calculation is used to determine how far the values vary from the mean (average) value. While a high standard deviation suggests that the data values are more dispersed, a low standard deviation suggests that the data values tend to be close to the mean.

To find the sample standard deviation weight,

we can use the formula:

[tex]s = \sqrt{((1/(n-1))} \sum((x - \bar x)^{2} ))[/tex]

where n is the sample size, x is the weight of each candy, [tex]\bar x[/tex] is the sample mean weight, and sum() means to add up the values.

We can first find the sample mean weight:

[tex]\bar x[/tex]= (0.98 + 0.85 + 0.92 + 0.98 + 0.71 + 0.88 + 0.86 + 0.75 + 0.85 + 0.85 + 0.86 + 0.78 + 0.75 + 0.75 + 0.74 + 0.82 + 0.85 + 0.91 + 0.78 + 0.72 + 0.81 + 0.81 + 0.81 + 0.84 + 0.87 + 0.85 + 0.89 + 0.77 + 0.85 + 0.97 + 0.74 + 0.89 + 0.82 + 0.86 + 0.82 + 0.84 + 0.91 + 0.87 + 0.94 + 0.85 + 0.71 + 0.83 + 0.87 + 0.94 + 0.81 + 0.81 + 0.78 + 0.77 + 0.85) / 50

[tex]\bar x[/tex] = 0.8456

Next, we can calculate the sample standard deviation:

s = √((1/(50-1)) x ((0.98-0.8456)² + (0.85-0.8456)² + ... + (0.77-0.8456)² + (0.85-0.8456)²))

s = sqrt(0.0045916)

s = 0.0678

Rounding to two decimal places, the sample standard deviation weight is 0.07 grams.

The number of adult and children in the group is given as follows:

The amounts are obtained by a system of equations, for which the variables are given as follows:

There were a total of 28 people, hence:

x + y = 28

y = 28 - x.

They spent a total of $308, hence:

15x + 8y = 308.

Replacing the second equation into the first, the value of x is given as follows:

15x + 8(28 - x) = 308

Using logarithm expressing log b100 in terms of x and y is logb100 = 2y + x

The logarithm of a number x to base a written as logₐy is such that when a is raised to the power of x,it equals y.

Since

We desire to express logb100 in terms of x and y.

So, we proceed as follows.

We have logb100, re-writing this, we have

logb100 = logb(25 × 2)

Now, applying the addition law of logarithm which states that

logab = loga + logb.

So, we have that

logb100 = logb(25 × 2)

logb100 = logb25 + logb2

= logb5² + logb2

Now applying the power rule of logarithm which states that logaⁿ = nloga

So,

logb100 = logb5² + logb2

= 2logb5 + logb2

= 2y + x

So, logb100 = 2y + x
