Answer:

For

y = (x^2 -4)/((x +2)(x^2 -49))

the numerator factors to (x -2)(x +2), so the factor of (x +2) will cancel with that in the denominator, leaving

y = (x -2)/(x^2 -49)

There are points of discontinuity at the hole, x=-2, and at each of the vertical asymptotes, at x=-7, +7.

The horizontal asymptote is y=0.

What is the form of the Pythagorean triple generator?

stepladder [879]

Answer:(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)

Step-by-step explanation:

We can rewrite left side into right side form

(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)

we can expand it

(x^2+y^2)^2=x^4+x^2y^2+x^2y^2+y^4

(x^2+y^2)^2=x^4+y^4+2x^2y^2

we can add and subtract 2x^2y^2

(x^2+y^2)^2=x^4+y^4+2x^2y^2+2x^2y^2-2x^2y^2

(x^2+y^2)^2=x^4-2x^2y^2+y^4+2x^2y^2+2x^2y^2

(x^2+y^2)^2=x^4-2x^2y^2+y^4+4x^2y^2

(x^2+y^2)^2=x^4-2x^2y^2+y^4+(2xy)^2

(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2

Write the quadratic equation whose roots are 6 and 3, and whose leading coefficient is 4

nekit [7.7K]

If α and β are the Roots of a Quadratic Equation ax² + bx + c then :

✿ Sum of the Roots : α + β $\mathsf{= \frac{-b}{a}}$

✿ Product of the Roots : αβ $\mathsf{= \frac{c}{a}}$

Let the Quadratic Equation we need to find be : ax² + bx + c = 0

Given : The Roots of a Quadratic Equation are 6 and 3

⇒ α = 6 and β = 3

Given : The Leading Coefficient of the Quadratic Equation is 4

Leading Coefficient is the Coefficient written beside the Variable with Highest Degree. In a Quadratic Equation, Highest Degree is 2

Leading Coefficient of our Quadratic Equation is (a)

⇒ a = 4

⇒ Sum of the Roots $\mathsf{: (6 + 3) = \frac{-b}{4}}$

⇒ -b = 9(4)

⇒ b = -36

⇒ Product of the Roots $\mathsf{: (6 \times 3) = \frac{c}{4}}$

⇒ c = 18 × 4

⇒ c = 72

⇒ The Quadratic Equation is 4x² - 36x + 72 = 0

In a batch of 8,000 clock radios 7% are defective. A sample of 1313 clock radios is randomly selected without replacement from

PIT_PIT [208]

Answer: Probability that the entire batch will be rejected is 0.611.

Step-by-step explanation:

Since we have given that

Number of clock radios in a batch = 8000

Probability of defective clock radio = 7%

According to question, we have mentioned that A sample of 13 clock radios is randomly selected without replacement from the 8,000 and tested.

We will use "Binomial distribution":

here, n = 13 and

p (probability of success) = 7% = 0.07

so, we need to find that

P(the entire batch will be rejected) = P(at least one of those test is defected)

So, it becomes,

P(at least one of those tested is defective) = 1 - P(none are defective)

So, P(none are defective ) is given by

$(1-0.07)^{13}\\\\=0.93^{13}\\\\=0.389$

So, P(at least one of those tested is defective) = 1 - P(none are defective)

= 1 - 0.389

= 0.611

Hence, Probability that the entire batch will be rejected is 0.611.

What is the approximate are of the shaded region's?

bixtya [17]

Calculate the area of the squares and the area of the circles, then subtract the area of the circle from the square.

Square with 14 m side:

Area of square = 14 x 14 = 196 square m.

Area of circle inside: 3.14 x 7^2 = 3.14 x 49 = 153.86 square m.

Area of shaded region: 196 - 153.86 = 42.14 square m.

Square with 8 m side:

Area of square: 8 x 8 = 64 square m.

Area of circle: 3.14 x 4^2 = 3.14 x 16 = 50.24 square m.

Area of shaded region: 64 - 50.24 = 13.76 square m.
