Suppose ABCD is a rhombus such that the angle bisector of ∠ABD meets

AD at point K. Prove that m∠AKB = 3m∠ABK. Help meee!! What do I put in the box shown below??

Answer:

7

Step-by-step explanation:

Note that

(g - [tex]\frac{1}{g}[/tex] )² = g² - 2 + [tex]\frac{1}{g^2}[/tex] = 51 - 2 = 49

Take the square root of both sides

g - [tex]\frac{1}{g}[/tex] = [tex]\sqrt{49}[/tex] = 7 ← the positive value

Final answer:

The expression (-2x⁴y²)³ simplifies to -8x¹²y⁶, by individually raising the coefficient and each variable to the third power.

Explanation:

To simplify the expression  (-2x⁴y²)³, you must raise both the numerical coefficient and the variables to the third power. Remember that raising a power to a power multiplies exponents and raising a negative number to an odd power results in a negative number.

Putting it all together, the expression simplifies to  -8x¹²y⁶.

Final answer:

Amy's printed picture, which is 225% the size of the original picture with a 4-inch side, would have a new side length of 9 inches, making it larger than the original. The statements truthfully state that the picture is larger and the size scale is 2 ¹/₄ in terms of the sides, but the area would be scaled by the square of the side scale factor.

Explanation:

When Amy prints a square picture at 225% of the original size, and the original picture has a side length of 4 inches, then the new side length can be determined by calculating 4 inches × (225/100). The correct calculation for the side length of Amy's printed picture should be 4 inches × 2.25 (or 225%) which equals 9 inches.

Therefore, the statements should be evaluated as follows:

Answer:

(1/9)

Step-by-step explanation:

Mary can choose from white,red,or pink construction paper to create a heart.

And she can use black, blue or green marker to write out her message and she can’t finish the valentine by sprinkling gold or silver glitter.

The probability that her valentine to her friend will be on either red or pink construction paper with black marker and gold glitter.

The probability that she uses red or pink construction paper = (2/3)

(since red or pink are two out of the total 3 sample spaces available for construction paper)

Probability that she uses black marker = (1/3)

(Black is one of the 3 sample spaces for markers)

Probability that she uses gold glitter = (1/2)

(Gold glitter is one of two sample spaces for glitters)

The required probability is then

(2/3) × (1/3) × (1/2) = (1/9)

Answer:

- 7 23/30

Step-by-step explanation:

-2 5/10 + -5 4/15

First simplify the fractions if possible

-2 1/2 + -5 4/15

Then, we need to get a common denominator

The common denominator in this case is 30

-2  1/2*15/15  + - 5 4/15*2/2

-2 15/30 + -5 8/30

Since the signs are alike we add

First the whole numbers

2+5 =7

Then the fractions

15/30+8/30 = 23/30

Add the fraction and the whole number together

7 23/30

Take the sign

- 7 23/30

If the fraction was improper, we would change it to a mixed number and add the whole numbers together

Final answer:

To find the sum of −2 5/10 and −5 4/15, convert them to improper fractions, find a common denominator, add them with the negative signs, and simplify if needed, resulting in −7 23/30.

Explanation:

To find the sum of −2 5/10 and −5 4/15, we first convert the mixed numbers into improper fractions. The first step is to add the whole numbers together, and then add the fractions separately.

Since both numbers are negative, when we add them, the answer will also have a negative sign, following the rule that when two negative numbers add, the answer has a negative sign. We find the common denominator for the fractions, which in this case is 30, and convert them accordingly. After adding the converted fractions, we simplify the result if possible.

To illustrate, for the whole numbers: −2 + (−5) = −7. For the fractions: −(5/10 × 3/3) + −(4/15 × 2/2) = −(15/30) + −(8/30) = −(23/30). Thus, the sum is −(7) − (23/30) or −7 23/30.

The trend will be positive because as the students get older their heights tend to get taller.

Answer:

B

Step-by-step explanation:

As students grow older, they will naturally grow taller because their bodies are developing and maturing. This means that as the values on the x axis increase, the values on the y axis will also increase.

The result of these type of correlation is that there will be a line increasing to the right. This is known as a positive trend.

Hey there!

Solving for equation: y = 9x + 2

Replace (for now) 9x + 2 for y in the equation: y = 3x + 12

y = 3x + 12

↪ 9x + 2 = 3x + 12

ADD by -3 on both of your sides

9x + 2 + (-3x) = 3x + 12 + (-3x)

If you solved that correctly you should get: 6x + 2 = 12

ADD by -2 on both of your sides

6x + 2 + (-2) = 12 + (-2)

Cancel out: 2 + (-2) because it gives you 0

Keep: 12 + (-2) because it helps us solve for our x-interpret

12 + (-2) = 10

NEW EQUATION: 6x = 10

DIVIDE by 6 on your sides

6x/6 = 10/6

Cancel out: 6x/6 because it gives you 1

Keep: 10/6 because it helps us solve for our x-intercept

10/6 = 10÷2/6÷2 = 5/3

Thus our x = 5/3

Solving for y = 9x + 2

Replace x with 5/3 since we found our x

y = 9(5/3) + 2

9(5/3) = 15

15 + 2 = 17

Thus our y = 17

Overall answer: a = 5/3 & y = 17 ✅ (Option D)

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

The mode is the value that appears most often in a data set. It is a measure of central tendency and is especially useful for describing categorical data or discrete sets. The correct answer is B. mode.

The mode, denoted as B in the options, is the value that occurs most frequently in a given data set. It is a statistical measure used to describe the central tendency of a dataset.

Unlike the mean, which calculates the average, and the median, which identifies the middle value, the mode focuses on the most recurring value. This is particularly helpful in analyzing categorical or discrete data. A dataset may have one mode (unimodal), more than one mode (multimodal), or no mode if all values occur with the same frequency.

Therefore, the mode is a valuable tool for understanding the distribution and characteristics of a dataset. (option B)

The complete question is:

Step-by-step explanation:

This is a 3, 4, 5 triangle

Answer: 5

If you graphed these three points on a graph you can see that the points (-2,0) and (-6,3) have the smallest length. First we want to find the slope of these points. We can use the formula y2 - y1 / x2 - x1. 3 - 0 / -6 - -2. 3-0 is 3 and -6 - -2 is -4. Two negatives make a postive. So the slope is 3/-4. We can't have a negative slope so change the -4 to a postive 4. Now square the slope 3/4 to get 9 and 16. We know the pythagoren therom formula is a^2 + b^2 = c^2. So square 3 and 4 to get 9 and 16 then add them to get 25. Square 25 and you get the answer 5.

Answer:

  c.  r = 3 + 2 cos(theta)

Step-by-step explanation:

At θ = 180°, the value of r is positive, but just a fraction of the value at θ = 0°. This eliminates choices 'b' and 'd'.

Choice 'a' would give r=3 and r=5 for those two cases, but the ratio of left extent to right extent looks smaller than 3/5. A graph of choice 'c' shows it matches the given figure.

Answer:

c.  r = 3 + 2 cos(theta)

Step-by-step explanation:

We have the height h(t) as

Answer:

Center at (4, 7) and radius is √49, or 7

Step-by-step explanation:

Didn't you mean (x-4)² + (y-7) ² = 49?

Comparing          (x-4)² + (y-7) ² = 49

to                          (x - h)^2 + (y - k)^2 = r^2, we see that the center is at (h, k)  =>  (4, 7) and that the radius is √49, or 7.

Answer:

[tex] f(x) = (x-4)(x-\frac{1}{2})^2 = x^3-5x^2+4.25x -1 [/tex]

Step-by-step explanation:

Recall, if we have a polynomial of the form [tex](x-a)^k \cdot (x-b)^m[/tex], then we say that a is a zero of multiplicity k and b is a zero of multiplicty m. For example, in the polynomial of the form [tex](x+5)^10(x-2)^3[/tex] -5 is a zero of multiplicity 10 and 2 is a zero of multiplicity 3. If we want to know the degree of the polynomial,  just add the multiplicity of both zeros (13 in our example).

In this case, we know that the degree of our polynomial should be at least 3(multiplicity 2 and multiplicity 1). So, lets take the polynomial of the form

[tex]f(x)=(x-a)(x-b)^2)[/tex].

In here, a is a zero with multiplicity 1 and b is a zero with multiplicity 2. We are also given that

[tex] f(0) = -1 = (0-a)(0-b)^2 = -a\codt b^2[/tex].

Which implies that [tex] 1 = a\cdot b^2[/tex]. Since the square of any number is a positive number, it must happen that a>0. So, we have that

[tex]b= \pm \sqrt[]{\frac{1}{a}}[/tex].

We can choose any value of a and solve for b. Let us choose a=4. So we can have b=1/2 or b=-1/2. Let's use b=1/2. So our polynomial would be

[tex] f(x) = (x-4)(x-\frac{1}{2})^2 = x^3-5x^2+4.25x -1 [/tex]

which we can easily check that f(0)=-1.

According to the property of an isosceles triangle, the measurements of the two non-included angle are equal.

=> This is an equilateral triangle because the two non-included angles and include angle ( 180° - 2 *60°)  are 60° .

This is an unique triangle.

Answer:No because you cannot form another triangle out of it. It only makes 1 shape.

Step-by-step explanation:

Answer:

27°

Step-by-step explanation:

Since BD is a diameter then arc BD = 180°

∠ APE = 180° - (90 + 63)° = 180° - 153° = 27°

The measure of the arc AE is equal to the angle at the centre subtended by it.

arc AE = ∠ APE = 27°

Answer:

13 plus .50 times J =A

Step-by-step explanation:

i dont really know how to explain this but here we go...

you already have $13 and if you get .50 for every cup you sell (J) then thats it really...

A = 13+ 0.50j is the equation which  represents the total amount A you have after selling j cups of orange juice.

Two or more expressions with an Equal sign is called as Equation.

Given that you have $13 and earn $0.50 for each cup of orange juice you sell .

We have to find an equation which  represents the total amount A (in dollars )you have after selling j cups of orange juice

A = 13+ 0.50j

13 is the initial amount and 0.50 is the slope of the given equation.

Hence, A = 13+ 0.50j is the equation which  represents the total amount A you have after selling j cups of orange juice.
