Step-by-step explanation:

Yes, the triangles ΔAYM ∼ ΔEDC by SSS criterion of similarity.

If the respective angles are congruent and the corresponding sides are proportional, two triangles are said to be similar.

The two triangles are similar if the three sides of one triangle are proportional to the three sides of the other.

According to SSS criterion of similarity:

CE / AM = ED / AY = CD / MY

3 / 6 = 4 / 8 = 5 / 10

1/2 = 1/2 = 1/2

Hence  ΔAYM and ΔEDC are similar by SSS criterion of similarity.

Answer:

B The measurement found using Ruler 2 is more accurate and more precise.

Step-by-step explanation:

We have to understand the concept here for accuracy and precision.

Accuracy is against some standard. So it is the measured value which is closely against a standard. Accuracy is less if the measured value is deviated from the standard.

Precision is about how closely individually measured values agree with each other. Precision doesn't concern with the standard value.

Now, third concept is significant numbers. It is up to how much decimal numbers an instrument can produce a result.

In ruler 2, you can see that there are more divisions for a whole inch. This means that the ruler 2 can measure more nearly to the standard value, as well as, for repeated measurements, it can give more precised figures due to the ability to read up to more decimal numbers after the decimal point.

Answer:

x² + 9x + 8 = 0

Step-by-step explanation:

A quadratic equation is expressed this way: ax² + bx + c = 0

So, so find the quadratic equivalent of (x + 2)² + 5(x + 2) – 6 = 0, we just have to do the multiplications then simplify.

(x + 2)² + 5(x + 2) – 6 = (x² + 4x + 4) + (5x + 10) - 6

After merging the terms of same degree, we get:

Answer:

$438.66

Step-by-step explanation:

The total percent taken is:

6.2% + 1.45% = 7.65%

7.65% of the paycheck is taken.

The total paycheck is 100% of the paycheck. Since 7.65% of the paycheck is taken, and 100% - 7.65% = 92.35%, then 92.35% of the paycheck is left.

Now we find 92.35% of $475.

To find a percent of a number, multiply the percent by the number and divide by 100.

92.35 * $475/100 = $438.66

Answer: $438.66

$438.66 , because 6.2+1.45=7.65 and then 100-7.65=92.35 and then you turn that into a percentage which would be 92.35% in decimal form would be .9235 which is the portion you’ll receive from your paycheck so you multiply that by $475 and you will get your final answer of $438.66

the answer is c) 59.5

We apply distributive property, which states that:

[tex](a + b) (c + d) = ac + ad + bc + bd[/tex]

So:[tex](y ^ 2 + 3y + 7) (8y ^ 2 + y + 1) =\\(y ^ 2) (8y ^ 2) + (y ^ 2) (y) + (y ^ 2) (1) + (3y) (8y ^ 2) + (3y) (y) + (3y) (1 ) + (7) (8y ^ 2) + (7) (y) + (7) (1) =\\8y ^ 4 + y ^ 3 + y ^ 2 + 24y ^ 3 + 3y ^ 2 + 3y + 56y ^ 2 + 7y + 7 =[/tex]

Step-by-step explanation:

12) Lowest Common Denominator of

[tex]\frac{p+3}{p^2+7p+10} \,\, and \,\, \frac{p+5}{p^2+5p+6}[/tex]

We should find the factors of denominators and then find the LCM of the denominators.Finding LCD is same as finding LCM.

Factors of p^2+7p+10 = p^2 +2p +5p+10 = p(p+2)+5(p+2) = (p+5)(p+2)

Factors of p^2+5p+6 = p^2+2p+3p+6 = p(p+2)+3(p+2) = (p+3) (p+2)

Now, rewriting the above equation with factors and finding the LCM

[tex]\frac{p+3}{(p+5)(p+2)} \,\, and \,\, \frac{p+5}{(p+3)(p+2)}\\[/tex]

LCM of (p+5)(p+2) and (p+3)(p+2) = (p+5)(p+3)(p+2)

The LCD is (p+5)(p+3)(p+2).

So, Option A is correct.

13. Divide

[tex]\frac{40x}{64y} \,\,by\,\, \frac{5x}{8y}[/tex]

by stands for division. The equation can be written as:

[tex]\frac{40x}{64y}\div\frac{5x}{8y}[/tex]

Division sign changed into multiplication, we take reciprocal of second term i.e,

[tex]\frac{40x}{64y}*\frac{8y}{5x}\\\\Solving\\\frac{40x*8y}{64y*5x}\\\\\frac{320xy}{320xy} \\\\1[/tex]

So, Option A is correct.

14. Simplify:

[tex]\frac{x+2}{x^2-6x-16} \div \frac{1}{9x} \\[/tex]

Factors of x^2-6x-16= x^2 -8x +2x -16 = x(x-8)+2(x-8) = (x-8)(x+2)

Putting factors in the above equation and changing division sign with multiplication we get,

[tex]\frac{x+2}{(x-8)(x+2)} * \frac{9x}{1}\\\frac{9x}{x-8}[/tex]

So, Option C is correct.

15. Simplify

[tex]\frac{4}{\frac{1}{4}-\frac{5}{2}}[/tex]

Solving denominator,

Taking LCM of 4 and 2 and subtracting we get

[tex]\frac{4}{\frac{1-(5*2)}{4}}\\\frac{4}{\frac{1-10}{4}}\\\frac{4}{\frac{-9}{4}}\\\frac{4*4}{-9}\\\frac{16}{-9} \,\,or\,\,\\\frac{-16}{9}[/tex]

Option D is correct.

16. Simplify:

[tex]\frac{7x+42}{x^2+13x+42}[/tex]

Making factors of x^2+13x+42= x^2 +6x+7x+42 = x(x+6)+7(x+6) = (x+7)(x+6)

Taking 7 common from numerator and putting factors in denominator we get,

[tex]\frac{7(x+6)}{(x+7)(x+6)}\\\\Cancelling\,\, x+6 \,\, from\,\, numerator \,\, and\,\, \\\\\frac{7}{(x+7)}[/tex]

Answer:

hello : h =5 and K= 1

Step-by-step explanation:

look this solution :

As per the given quadratic function, the value of the vertex of the graph is written as (5, 1)

A quadratic function is a polynomial function of degree 2, typically written in the form f(x) = ax² + bx + c, where a, b, and c are constants, and a ≠ 0. However, the given quadratic function is already expressed in the desired form, f(x) = a(x - h)² + k, which is known as vertex form. In this form, (h, k) represents the coordinates of the vertex of the parabola.

Now, let's rewrite the given quadratic function f(x) = 2x² - 20x + 51 in the vertex form. To achieve this, we'll complete the square:

Step 1: Factor out the leading coefficient 'a' from the x² and x terms. f(x) = 2(x² - 10x) + 51

Step 2: Complete the square inside the parentheses by adding and subtracting the square of half of the coefficient of the x-term (in this case, -10/2 = -5, and (-5)² = 25). f(x) = 2(x² - 10x + 25 - 25) + 51

Step 3: Group the perfect square trinomial and the constant term inside the parentheses. f(x) = 2((x - 5)² - 25) + 51

Step 4: Distribute the leading coefficient 'a' back into the parentheses. f(x) = 2(x - 5)² - 50 + 51

Step 5: Combine the constants. f(x) = 2(x - 5)² + 1

Now, the quadratic function is in the form f(x) = a(x - h)² + k, where a = 2, h = 5, and k = 1.

Therefore, the vertex of the parabola is (h, k) = (5, 1).

A-p-e-x :)

(2x + 6x + 4) All you need to find is numbers that can all be divided by 2.

To write a trinomial with a GCF of 2, start by factoring out the GCF from each term. For example, the trinomial 4x^2 + 6xy + 8y^2 can be factored as 2(2x^2 + 3xy + 4y^2).

A trinomial is an algebraic expression with three terms. The greatest common factor (GCF) is the largest factor that all the terms share. To write a trinomial with a GCF of 2, we can start by factoring out the GCF from each term. Let's say the original trinomial is:

4x^2 + 6xy + 8y^2

The GCF of the trinomial can be found by listing the factors of each term and selecting the highest common factor. In this case, the factors of 4x^2 are 2 and 2x^2, the factors of 6xy are 2, 3, x, and y, and the factors of 8y^2 are 2^3 and y^2. The highest common factor is 2, so we can factor out 2 from each term:

2(2x^2 + 3xy + 4y^2)

This is a trinomial with a GCF of 2.

Step-by-step explanation:

Of the 20 samples taken, ...

Most of the samples fall in the range 60%–75%, so we have to conclude that it is most likely that the fraction of students who play video games is in that range.

Angle A= 60

You add angles A and D together and set them equal to 180 because opposite sides in a parallelagram =180. Then you solve for x and get 30 and you should then plug in 30 to angle A and get 60.

Answer:

Step-by-step explanation:

The figure is rotated 90 degrees clockwise then translated down 3 units and left 2 units.

The blue triangle becomes the purple triangle by rotating 90° clockwise then translated down 3 units and left 2 units, so, option D is correct.

A shape is translated when it is moved to the left, right, up, or down without turning. Congruence is demonstrated by the fact that the translated shapes (or the image) seem to be the same size as the original ones. Simply said, they have changed their path or directions.

Given:

The blue triangle becomes the purple triangle in the graph,

All rotations are about the origin,

The Clockwise motion, also known as CW, moves from top to bottom, then down and left, and then back to top in the same manner as a clock's hands.

4.4

Step-by-step explanation:

The tenth place in this number is 4.432, so that should be the last digit.

Now, we need to know wether to round up or down. That is determined by the digit that comes after it. If that digit, here it is the hundredth, is 0-4, it rounds down, if it is 5-9, it rounds up. Our next digit is 3, which goes into the first category, so the number rounds down, so the tenth remains the same. That leaves us with 4.4.

Answer:

4.4

Step-by-step explanation:

The tenth decimal place is one to the left of the decimal. The hundreth decimal places is two digits to the right and so on an so forth. Knowing this, you apply the basic rules of rouding. If the digit to the left of the digit being rounded is greater than five, the digit is rounded up one and the others are discarded. In this case, the digit to the left of the digit in subject is less than five, 3. Therefore, the tenth decimal stays the same and the others are discarded.
