Answer: Pythagorean Theorem is not the justification for the proof.

Step-by-step explanation:

We can get the right answer with help of the below proof of Pythagoras theorem,

Since, Here ABC is the triangle in which CD is the altitude from the point C.

Where,  D\in AB ( shown in figure)

Here, segment BC = a, segment CA = b, segment AB = c, segment CD = h

segment DB = y , segment AD = x  

y + x = c ( c over a equals a over y and c over b equals b over x)

Since, \triangle ABC\sim \triangle ACD ⇒ a/c=y/a and \triangle ABC\sim \triangle BCD⇒  b/x=c/b ( Pieces of Right Triangles Similarity Theorem)

⇒ a^2=cy and b^2=cx  (  Cross Product Property)

a^2 + b^2 = cy + b2 (Addition Property of Equality)

a^2 + b^2 = cy + cx  

a^2 + b^2 = c(y + x)  

a^2 + b^2 = c(c)

a^2 + b^2 = c^2

What is the multiple zero and multiplicity of f(x) = (x − 3)(x − 3)(x + 5)? a. Multiple zero is 5; multiplicity is 1 b. Multiple
dolphi86 [110]

Answer:

c. Multiple zero is 3; multiplicity is 2

Step-by-step explanation:

The factor is repeated, that is, the factor  ( x  −  3 )  appears twice. The number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity. The zero associated with this factor,  x  =  3 , has multiplicity 2 because the factor  ( x  −  3 )  occurs twice.

Then

Multiple zero is 3; multiplicity is 2.

Below are some data examining whether reading the textbook for this course is related to class enjoyment.
Reil [10]

Answer:

13.36

Step-by-step explanation:

I will first create a table

X. Y. XY. X²

1. 20. 20. 1

2. 24. 48. 4

3. 35. 105. 9

4. 46. 184. 16

5. 67. 335. 25

6. 80. 480. 36

1. 12. 12. 1

2. 34. 68. 4

3. 34. 102. 9

5. 78. 430. 25

ΣX = 32

ΣY = 430

ΣXY = 1744

ΣX² = 130

n = 10

The formula for regression line is given as :

Y = a + bX

a = intercept

b = slope

The question requires us to find b which is the slope.

b = nΣXY-ΣXΣY/nΣX²-(ΣX)²

= 10x1744-32x430/10x130-(32)²

= 17440-13760/1300-1024

= 3680/276

= 13.36

b = 13.36

If 12y=75+5x+2x-1. What is the value of x
AleksandrR [38]

Answer:

x = \frac{12y - 74}{7}

Step-by-step explanation:

12y = 75 + 5x + 2x - 1

combine like terms:

12y = 74 + 7x

subtract 74 from both sides:

7x = 12y - 74

divide both sides by 7:

x = \frac{12y - 74}{7}
