Please help with question 14

Answer:

(5, - 4)

Step-by-step explanation:

Given a quadratic in standard form : ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

x² - 10x + 21 ← is in standard form

with a = 1, b = - 10, so

[tex]x_{vertex}[/tex] = - [tex]\frac{-10}{2}[/tex] = 5

Substitute x = 5 into the quadratic for the corresponding value of y

y = 5² - 10(5) + 21 = 25 - 50 + 21 = - 4

vertex = (5, - 4)

Step-by-step explanation:

∠YXZ and ∠VXU are vertical angles, and therefore are congruent.

∠YXZ ≅ ∠VXU, Vertical ∠'s ≅

Next, we're given that lines YZ and UV are parallel.  That means that ∠YZV and ∠UVZ are alternate interior angles, and therefore congruent.

∠YZV ≅ ∠UVZ, If lines ||, then alternate interior ∠'s ≅

If two triangles have two pairs of congruent angles, then the third pair must also be congruent, making the two triangles similar.

△XYZ ~ △XUV, AA

Since the triangles are similar, then by definition, their sides are proportional.

XY/XU = YZ/UV, Definition of Similar Polygons

YZ || UV - Given

YXZ = VXU - Vertical triangles =

YZV = UVZ - If lines ||, alternate internal triangles =

XYZ ~ XUV - AA

XY/XU = YZ/UV - Definition of Similar Polygons

Answer:  The overall percent loss is 28%.  

Step-by-step explanation:  Given that a stock loses 10% of its value on Monday and on Tuesday it loses 20% of the value it had at the end of the day on Monday.

We are to find the overall percent loss in value from the beginning of Monday to the end of Tuesday.

Let x represents the value of a stock at the beginning of Monday.

Then, the value of the stock at the end of Monday is given by

[tex]x-10\%\times x=x-\dfrac{10}{100}x=x-\dfrac{x}{10}=\dfrac{9}{10}x.[/tex]

So, the value of the stock at the beginning of Tuesday is [tex]\dfrac{9}{10}x.[/tex]

Therefore, the value of the stock at the end of Tuesday is given by

[tex]\dfrac{9}{10}x-20\%\times\dfrac{9}{10}x\\\\\\=\dfrac{9}{10}x-\dfrac{20}{100}\times\dfrac{9}{10}x\\\\\\=\dfrac{9}{10}-\dfrac{9}{50}x\\\\\\=\dfrac{36}{50}x\\\\\\=\dfrac{18}{25}x\\\\\\=x-\dfrac{7}{25}x\\\\\\=x-\dfrac{28}{100}x\\\\\\=x-28\%x.[/tex]

Thus, the overall percent loss is 28%.

Answer:

m = 12f

Or

m/12 = f

Step-by-step explanation:

The conversion from inches to feet involves a constant factor of variation which is 12. Inches is a smaller unit while feet are obtained by dividing the inches with 12.

As we know,

1 foot = 12 inches

Given in the question:

m = measurement in inches

and

f= measurement in feet

Hence the equation will be:

m = 12f

Or

m/12 = f ..

Equations would you use the zero product property on is (x-5)(x-10)=0

The zero product property states that if a⋅b=0 then either a or b equal zero.

To get the positive value we have consider those factor which have negative in their expression.

As, by the property if we equate both of them equal to zero one by one then we get the desired value.

(x-5)(x-10)= 0

if x-5=0

x=5

and if, x-10=0

x=10

Answer:

lcm = 4

Step-by-step explanation:

20 = 2 × 2 × 5 ← product of prime factors

12 = 2 × 2 × 3 ← product of prime factors

The lowest common multiple (lcm) = 2 × 2 × 5 × 3 = 60

Answer:

60

Step-by-step explanation:

First, break down each of the numbers into their prime factors.

20 = 2² x 5

12 = 2² x 3

To find the LCM, underline each of the prime numbers. If there is a repeated prime number, underline the one with the largest possible value. For example, if there is 3² and 3³, underline the second one. In this case, the values are the same, so just underline one.

20 = 2² x 5

12 = 2² x 3

Next, multiply all the underlined numbers.

LCM (20, 12) = 2² x 5 x 3 = 60

Answer:The last experimental design is the best of the options: 'Compare the average number of

tomatoes that are produced by 10 tomato plants that are grown in clay soil to

the average number of tomatoes that are produced by 10 tomato plants that are

grown in sandy soil''.

The first two experimental designs measure the growth of

tomato plants, which is not necessarily related to the yield of tomatoes. The

third experimental design compares the tomato yield of the two

soils with only one plant grown in each soil. Obviously, the result obtained

from this experiment would be statistically weak. The last experimental design

compares tomato yield and also uses a larger number of plants in each soil

type, so the results obtained would be of slightly greater statistical

significance.

Step-by-step explanation:

The mean absolute deviation is M = 2.2

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the total number of plants be n

Now , the value of n = 10

And , the number of tomatoes on each plant is given by set A

Now , the value of set A = { 5 , 5 , 5 , 6 , 9 , 10 , 10 , 10 , 10 , 10 }

So , the total number of tomatoes = 5 + 5 + 5 + 6 + 9 + 10 + 10 + 10 + 10 + 10

The total number of tomatoes = 80 tomatoes

Now , the mean number of tomatoes = 80 / 10 = 8

And , the mean deviation is M

where M = 1/10 [ ( 8 - 5 ) + ( 8 - 5 ) + ( 8 - 5 ) + ( 8 - 6 ) + | ( 8 - 9 ) | + 5( 10 - 8 )

M = ( 1/10 ) [ 3 + 3 + 3 + 2 + 1 + 5 ( 2 ) ]

M = ( 1/10 ) [ 22 ]

M = 2.2

Therefore , the value of M is 2.2

Hence , the mean deviation is 2.2

To divide fractions, multiply the first fraction by the reciprocal of the second fraction. In this case, the answer is 9/4.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of 1/3 is 3/1. So, we have:

3/4 ÷ 1/3 = 3/4 * 3/1 = 9/4.

The answer, 9/4, cannot be further reduced to lowest terms since 9 and 4 do not have any common factors other than 1.

Answer: 29 degrees is the answer

Step-by-step explanation:

The bisector is the line that divides the angle, and rhombus diagonally. So, basically you're just dividing 58 in half. Which is 29 degrees.

The measure of each of the two angles formed by the bisector of the diagonal of a rhombus will be 29 degree.

Angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

We have,

A Rhombus with one of its angle equal to 58°.

Now,

Bisector of an angle, divides an angle into two equal parts.

So,

From the above mentioned definition,

i.e.

[tex]=\frac{58}{2} = 29^0[/tex]

So, the measure of each angle is 29°.

Hence, we can say that the measure of each of the two angles formed by the bisector of the diagonal of a rhombus will be 29 degree.

The graph of k(x)=2(x-8)², a quadratic function, will be an upwards-opening parabola with a vertex at (8,0). To compare it with the graph of f(x), we need more details about f(x), which could be linear, quadratic, or a different type of function entirely. The comparison can focus on attributes like shape, orientation, position, steepness, continuity, differentiability, or periodicity.

The function k (x) = 2 (x-8)² is a quadratic function where 2 is the coefficient, and 8 is the amount that the graph is shifted to the right in the x coordinate. This graph will be a parabola that opens upwards, with a vertex at the point (8,0) due to the transformation in the x term (x-8).

To compare the graph of f(x) with the graph of k(x), we first need to understand the characteristics of f(x). For example, if f(x) is also a quadratic function, we can compare their shapes, orientations (upward or downward opening), positions (based on vertex and line of symmetry), and steepness (determined by the absolute value of the coefficient -- in this case, 2).

If f(x) is a linear function, it will be a straight line and we can compare the orientation, steepness (slope), and position (y-intercept). Or if f(x) is a different type of function entirely, the comparison will focus more generally on attributes like continuity, differentiability, periodicity, etc. Therefore, without additional details about f(x), a complete comparison isn't possible.

For the graph will you have a empty or colored in circle?

If the symbol is ≥ or ≤ then the circle will be colored in. This represents that the number the circle is on is included.

If the symbol is > or < then the circle will be empty. This represents that the number the circle is on is NOT included.

Which direction will the ray go?

If the variable is LESS then the number then the arrow will go to the left of the circle.

If the variable is MORE then the number then the arrow will go to the right of the circle.

In this case your inequality is:

3 ≥ q OR q ≤ 3

aka 3 is greater then q OR q is less then 3

This means that the graph will have an colored circle and the arrow will go to the left of 3. Look at image below.
