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

Can someone please help me find the perimeter of the figure, and round it to the nearest hundredth.
Answer:
perimeter = 40.57 in
Step-by-step explanation:
perimeter of circular = π(diameter) = π8 = 25.13 in
25.13/2 = 12.57 in (divide by 2 for half-circle)
12.57 + 10 + 8 + 10 = 40.57 in
4. The pet store usually sells 12 puppies every 9 days. At this rate, how long will it take
them to sell 174 puppies?
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]

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]
Approximate
[tex]x = 17.5[/tex]

According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white in a 3:1 ratio. That is, each plant has probability 3/4 of having red blossoms, and the blossom colors of separate plants are independent. Using the Binomial distribution, what is the exact probability that more than 7 out of 10 these plants have red blossoms
Answer:
The answer is "0.250".
Step-by-step explanation:
Given:
[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]
[tex]= \binom{10}{7}(0.75)^7(1-0.75)^{10-7} \\\\=120 \times (0.75)^7 \times (0.25)^3\\\\=0.250[/tex]
The area of a square is 1800 in2, how long is each diagonal?
9514 1404 393
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.

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?
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

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?
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.

Two people share proceeds of a business venture in the ratio 2:3 If the proceeds came to GHS 2,350,000 how much does each get?
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.

Answer:
-21, 13
Step-by-step explanation:
If Z is located to the right of Y, its point on the number line is -4+17 = 13.
If Z is located to the left of Y, its point on the number line is -4-17 = -21.
There are two possible locations for Z on a number line.
_____
In a 2-dimensional plane, there are an infinite number of locations of distance 17 from a given point. The set of all of them makes a circle on the plane, with radius 17.
In 3-dimensions, the set of points becomes a sphere with radius 17.
