A designer is adding a pendant to a jewelry collection. The shape of the pendent can be defined by the equation y = StartFraction 1 Over 20 EndFraction x squared EndFraction. If the largest dimension of the pendant is 10 cm wide, what is the greatest length? 1. 25 cm 2. 50 cm 5 cm 10 cm.

Answers

Answer 1

The greatest length of the considered pendent is given by: Option A: 1.25 cm

What does graph of a function represents?

Suppose the considered function is [tex]y = f(x)[/tex]

Then, we will plot points as [tex](x,y) =(x,f (x))[/tex] for all values of 'x' which are in domain of the function.

For this case, the given function's graph (the graph of [tex]y = \dfrac{x^2}{20}[/tex] ) is shown below.

We're given that the largest dimension is of 10 units.

Let this be the line segment parallel to the x-axis, intersecting y-axis at [tex]y = y_0[/tex]

Now, since the curve is symmetric over (as for x or -x, we get same y), so the line segment that is parallel to x axis also intersects the graph at symmetric places. Let those points be in front of [tex]x_0[/tex] and [tex]-x_0[/tex]

For those inputs, the output is [tex]y = y_0[/tex],

Also, we have length of the line segment as of 10 units, this is the difference between those symmetric inputs.

Thus, we get two equations:

[tex]x_0 - (-x_0) = 10[/tex]

[tex]f(x_0) = y_0 = \dfrac{x_0^2}{20}[/tex]

From first one, we get:

[tex]x_0 = 10/2= 5[/tex]

Thus, we get:

[tex]f(x_0) = y_0 = \dfrac{x_0^2}{20}\\\\f(5) = y_0=\dfrac{25}{20} = 1.25[/tex]
Since the length of y_0 is the shortest distance from x-axis to that parallel line segment, this is the second dimension needed.

Thus, the greatest length of the considered pendent is given by: Option A: 1.25 cm

Which ratios are equivalent? PLEASE EXPLAIN :D

A) 6/8, 2/3
B) 1/5, 12/15
C) 9/12, 3/4
D) 10/12, 5/7

Answers

Answer:

C) 9/12, 3/4

Step-by-step explanation:

To find which ratios are equivalent, we have to simplify them.

A)

6 and 8 have a GCF of 2, so 6/2 = 3, and 8/2 = 4. We do not get 3/4 as the fraction- we get 2/3. Thus, this cannot be the correct answer.

B)

The GCF of 12 and 15 is 3, so 12/3 = 4, and 15/3 = 5. We do not get 4/5 as the fraction- we get 1/5. Thus, this cannot be the correct answer.

C)

The GCF of 9 and 12 is 3, so 9/3 = 3, and the 12/3 = 4. We get the fraction as 3/4, which 3/4 = 3/4

Therefore, the answer is C).

The answer to this question is: C

The following bar chart shows the number of different types of animals at two county fairs. Fair X had a total of 645 animals, and fair Y had a total of 590 animals. Which of the following statements is supported by the bar chart?

Answers

Answer:

The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.

Step-by-step explanation:

From the bar chart,  we can see that 100 goats were present at fair X and Y

Let us now calculate the percentage of goats at each fair:

Fair X = 100/645 * 100 = 15.5%

Fair Y =100/590 *100 = 16.9 %

Hence there was a greater percentage of goats at fair Y than at fair X.

The bar chart is missing and so i have attached it.

Also, the question is incomplete and the missing part of the question is;

Which of the following statements is supported by the bar chart?

a) The total number of cows, pigs, and horses combined is less at fair X than at fair Y.

b) Fair X has at least 20 more chickens than fair Y.

c) At fair X, the number of sheep is twice the number of horses.

d) The percentage of all animals at fair Y that are goats is equal to the percentage of all animals at fair X that are goats.

e) The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.

The only Statement that supports the bar chart is statement E.

A) Looking at the bar chart attached, we can see that;

At fair X: Cows = 50, Pigs =60, Horses = 80. Total = 50 + 60 + 80 = 190

At fair Y:  Cows = 60, Pigs = 80, Horses = 40. Total = 60 + 80 + 40 = 180

Total in fair X is greater than total in fair Y. Therefore statement in question is false.

B) From the bar chart;

At fair X; chickens = 90

At fair Y; chickens = 80

Difference = 90 - 80 = 10

Thus,statement in question is wrong.

C) At fair X;

Sheeps = 140

Horses = 80

Twice number of horses is not same as sheep. Thus, statement in question is wrong.

D) Total number of animals at fair Y = 60 + 80 + 40 + 80 + 100 + 90 + 140 = 590

Percentage that are goats = 100/590 × 100 = 16.95%

Total number of animals at fair X = 50 + 60 + 80 + 90 + 100 + 125 + 140 = 645

Percentage that are goats = 100/645 × 100 = 15.5%

The percentages are not equal and so the statement in the question is wrong.

E) True because from D above percentage that are goats at fair Y are more than the percentage that are goats at fair X.

Answers

Answer:

2.25

Step-by-step explanation:

Notice how the common ratio is -1/3, which means the series passes part 1 of the convergence test because -1/3 is in between -1 and 1.

We can also represent this as a summation series of

[tex]Σ3( - \frac{1}{3} ) {}^{n - 1} [/tex]

Since we can represent this a summation series, we can use that convergent value is equal to

[tex] \frac{a _{1} }{1 - r} [/tex]

where a1 is initial term and r is common ratio.

R is -1/3

A1 is 3.

[tex] \frac{3}{1 - \frac{ - 1}{3} } = \frac{3}{ \frac{4}{3} } = 2.25[/tex]

Which of the following is not a characteristic of a point?

A. Flat surface
B. Named using a capital letter
C. No depth or width
D. Undefined term

Answers

Answer:

D. Undefined term

Step-by-step explanation:

Points are flat surfaces, named using a capital letter, and have no depth or width because they are on a FLAT plane. Just like lines are named "line A", are on a flat surface, and have no depth or width, points also share these characteristics because they are all on a plane. However, a point is not an undefined term, it is a defined term.

A point is a geometric feature used for the definition of geometric objects

The option which is not a characteristic of a point is option A:

A. Flat surface

The reason for the above selection is as follows:

A point in Euclidean geometry is a concept that defines an exact spatial location

The characteristics of a point are:

A point only represents position, it has no dimensions; It does not have a thickness, width, or lengthThe explanation given of a point is made by use of descriptions or examples and therefore, a point is considered an undefined termA point can be denoted or named using capital letters and represented using dots

An incident ray of light strikes water at an angle of 30°. The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33. What is the angle of refraction rounded to the nearest whole number? 22° 24° 30° 42°.

Answers

The measure of the angle of refraction is 22 degress, the correct option is A.

What is the angle of refraction?

The angle made by a refracted ray with a perpendicular to the refracting surface.

Given

An incident ray of light strikes water at an angle of 30°.

The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33.

In order to determine the angle of the refracted ray, we may apply Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is constant for a given wave when it passes through two different media.

The angle of the refraction is given by;

[tex]\rm 1.0003 \times sin(30) = 1.33 \times sin(\phi)\\\\ \rm 1.0003 \times 0.5 = 1.33 \times sin(\phi)\\\\Sin\phi=\rm \dfrac{1.0003 \times 0.5 }{1.33}\\\\Sin\phi=0.37\\\\\phi = 22[/tex]

Hence, the measure of the angle of refraction is 22 degress.
