y^4-2y^2+1...........

Answers

Answer 1

Answer:

(y²-1)²

Step-by-step explanation:

Given:

y⁴ - 2y² + 1

Find:

Factor of given equation

Computation:

y⁴ - 2y² + 1

Change given equation in quadratic equation.

(y²)² - 2(y)²(1) + (-1)²

We know that

(a)² - 2(a)(b) + (b)²

(a-b)²

So,

(y²)² - 2(y)²(1) + (-1)²

(y²-1)²

Answer:

17.5 ft

Step-by-step explanation:

Given

[tex]Ladder = 18ft[/tex]

[tex]\theta = 76[/tex]

Required

The height which the ladder reaches on the wall

The question is illustrated with the attached image (solve for x).

Using sine formula, we have:

[tex]\sin(76) = \frac{x}{18}[/tex] --- i.e. sin = opposite/hypotenuse

Make x the subject

[tex]x = 18 * \sin(76)[/tex]

[tex]x = 18 * 0.9703[/tex]

[tex]x = 17.4654[/tex]

find the value of" A" such that triangle DEF with vertices D (a,1) , E(10,7) and F(7 ,11) is a right angle at E?​

Answers

a=2

Answer:

(m1) slope of DE=(7-1)/(10-a)=6/(10-a)

(m2) slope of EF=(11-7)/(7-10)=4/-3=-4/3

since line are perpendicular

m1m2=-1

6/(10-a) ×-4/3=-1

6/(10-a)=3/4

6×4=3(10-a)

24=30-3a

3a=30-24

a=6/3=2

Answers

Answer:

GHS 940,000 and GHS 1,410,000

Step-by-step explanation:

Total Ratio, thus 2+3 = 5 = 2,350,000

2/5 × 2,350,000 = 940,000

3/5 × 2,350,000 = 1,410,000

In conclusion, the money was shared at GHS 940,000 and GHS 1,410,000 among the two.

Answers

Answer:

Approximately 131 days

Step-by-step explanation:

Let the store will take x days to sell 174 puppies.

Since, there is a relation of direct proportion between the puppies sold and number of days.

So,

[tex] \frac{12}{9} = \frac{174}{x} \\ \\ x = \frac{174 \times 9}{12} \\ \\ x = \frac{1,566}{12} \\ \\ x = 130.5 \: \\ \\ x \approx \: 131 \: days[/tex]

The answer is "0.250".

Step-by-step explanation:

[tex]P(X=7) \\\\ n=10\\\\ p=0.75\\\\x \sim Binomial (n = 10, p = 0.75)\\[/tex]

[tex]P(X=7) =\binom{n}{x} P^{x} (1-p)^{(n-x)} \\\\[/tex]

A computer password contains six characters but does not permit repetition of any characters (either letters or numbers). If uppercase and lowercase letters are used, how many possible passwords are there?

Answers

Answer:

[tex]\frac{62!}{56!}[/tex]

Step-by-step explanation:

We can either look at all 62 characters (2 * 26 in the alphabet and 10 digits), choose 6 of them, and add the fact that we care about their order - so multiply by 6! and we get [tex]\binom{62}{6}\cdot 6! = \frac{62!}{6!\cdot 56!} \cdot 6! = \frac{62!}{56!}[/tex]

Or, we can look atr all the permutations of all the characters and take into account that we DON'T care about the order of the 56 after the first six. Getting [tex]\frac{62!}{56!}[/tex] immediately.

Answers

Answer:

  60 in

Step-by-step explanation:

The area of a square can be computed as ...

  A = (1/2)d^2 . . . . where d is the length of the diagonal

For an area of 1800 in^2, the diagonal length can be found as ...

  1800 in^2 = 1/2d^2

  3600 in^2 = d^2

  d = √3600 in = 60 in

The length of each diagonal is 60 inches.
