Answer 2

Answer:

[tex] {x}^{2} + 18x + 81[/tex]

Step-by-step explanation:

[tex](x + 9) {}^{2} [/tex]

Apply foil method.

[tex](x + 9) {}^{2} = (x + 9)(x + 9)[/tex]

Multiply the first terms, X

[tex]x \times x = {x}^{2} [/tex]

Multiply outer terms, 9 and x.

[tex]x \times 9 = 9x[/tex]

Multiply inner terms,

[tex]9 \times x = 9x[/tex]

Multiply outer terms.

[tex]9 \times 9 = 81[/tex]

Add the inner and outer terms

[tex]9x + 9x = 18x[/tex]

Write in standard form

[tex] {x}^{2} + 18x + 81[/tex]

What is the value of y?

Answers

In a 30 · 60 · 90 triangle, the smallest side is x, the hypotenuse is 2x and the longer leg is x√3. So, in our 30 · 60 · 90, we have the hypotenuse is 6, so 6 ÷ 2 = 3 to give us the smallest leg (in this case is y), so y = 3. Because the longer leg is √3 · the smallest leg, 3√3 is the longest leg.

x = 3√3

y = 3

A baseball player hits a ball towards a 20-foot wall 400 feet away. The path of the ball is modeled by the function, f(x)=-0.002(x-220)^2 +86, where x is the distance of the ball from the batter and f(x) is the height of the ball.

Based upon the function, f(x), what is the maximum height of the ball will reach?

Do these three sides make a triangle? Is it unique? 1.4 miles, 1.8 miles, and 4.5 miles

Yes, it is a triangle and it is unique.

Yes, it is a triangle, but it is not unique.

No, it does not make a triangle.​

Answers

Answer:

No It Is Not A Triangle

Step-by-step explanation:

To be a triangle the 2 shorter sides have to add up greater than the longest side, 1.4+1.8=3.2 which is not grater than 4.5

1. The sum of the angles of a triangle are equal to 180 degrees. One angle measure is 18 degrees, the second angle measure is 62 degrees, and the third angle measure is x.

Write the equation that can be used to solve for x.​

If K is the midpoint of JL , JK = MN, LM = 3JK and JN = 78, find LN

Answers

A. 42

JN, which is the whole line, equals 78. We learned that JK, KL, and MN are all equal, and that LM equals three points.

So, there are 6 parts to the line in total. Dividing 78 by 6 gives you 13 for a sixth of the line.

Now, to find LN all you have to do is know that LM is 13 times three. And just add one more 13 from MN.

13 x 4 = 42 as your answer. I hope you were able to follow my explanation lol

If K is the midpoint of JL, JK = MN, LM = 3JK, and JN = 78, The value of LN will be 52. Option C is correct.

What are arithmetic operations?

The area of arithmetic operations encompasses the study of numbers and their operations, which are essential to all other branches of mathematics. These systems use the four operations of addition, subtraction, multiplication, and division as their foundation.

It is given that, K is the midpoint of JL, JK = MN, LM = 3JK, and JN = 78,

The entire line, or JN, equals 78. We discovered that LM equals three points and that JK, KL, and MN are all equal. The line, therefore, has a total of 6 sections. For a sixth of the line, you get 13 by dividing 78 by 6. Now, all you need to do to find LN is be aware that LM is 13 times three. Simply add one additional 13 from Minnesota.As a result,

LN=13 x 4

LN= 52

Thus, the value of LN will be 42. Option C is correct.

Answers

Answer:

6:5:4

Step-by-step explanation:

6 + 5 + 4 = 15

3000/15 = 200

200 x 6 = 1200 = eldest

200 x 5 = 1000 = 2nd eldest

1200 + 1000 = 2200

3000 - 2200 = 800

200 x 4 = 800 = youngest

Answer 6 : 5 : 4

Step-by-step explanation:

Its simply because

1200 ÷ 6 is 200 which is a whole number... If you divide for example 1200 by 7 it wont give you a whole... And also the first number of the ratio should be the greatest since the first child got the most money and the last the least which means the least should be the smallest number.

Find the value of X. Round to the nearest tenth.

Answers

Answer:

x = 4.1 cm

Step-by-step explanation:

The chord is divided into two equal parts. A right angle is formed, therefore, to find x, apply pythagorean theorem.

c² = a² + b²

Where,

c = 8.8 cm

a = x

b = 15.6/2 = 7.8 cm

Plug in the values

8.8² = x² + 7.8²

8.8² - 7.8² = x²

16.6 = x²

√16.6 = x

x = 4.1 (to nearest tenth)

Radius, r = 1cm

Length = height, h = 12

Cost per cm³ = AED0.50

VOLUME OF CYLINDER = pi * r² * h

Volume = 3.14 * 1² * 12
