Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The only transformation that would make a shape smaller or bigger is dilation.

Since this dilation is going from bigger to smaller you will have to use a number from in between 0 and 1.

Step-by-step explanation:

Answer:

T= 62

Step-by-step explanation:

First you need to distribute

8t+16-3t+12=6t-42+8

Next you need to simplify the problem

5t+28=6t-34

-5 +34  -5.+34

62=1t

X=5

Step-by-step explanation:

3+3 is the example and x+5 will be 5+5 since it will be the same. So 2 5

Answer:

X=5

Step-by-step explanation:

hmmmmmm ok

2x-3+3=x+5    You need to even out each side of the equation so

2x=x+5

2x5 is equivalent to 5+5 so x=5.

Step-by-step explanation:

The area of a kite can be found, given the lengths of its diagonals

The correct option for the area of the kite ABCD is option C;

C) 162 square inches

The reason the selected value is correct is as follows:

The given parameters in the kite ABCD are;

AC = 18 inches

BE = 9 inches

The required parameter:

The area of the kite

Solution:

The area of a kite is given by the product of the lengths of the diagonals divided by 2

Therefore, we have;

[tex]\mathbf{The \ area \ of \ the \ kite \ ABCD} = \dfrac{Length (AC)\times Length (BD)}{2}[/tex]

The length of BD = BE + DE

BE = DE Given that AC is a perpendicular bisector of BD, by the properties of a kite

∴ BD = BE + BE = 2 × BE by substitution property

Therefore;

[tex]The \ area \ of \ the \ kite \ ABCD = \mathbf{\dfrac{Length (AC)\times 2 \times Length (BE)}{2} }= AC \times BE[/tex]

Which gives;

The area of the kite ABCD = 18 inches × 9 inches = 162 square inches

Step-by-step explanation:

length of finite strings = 100

number of letters : 4 { a,b,c,d }

Determine the number of strings that use ≤ two different letters

since the number of letters is 4 and we are allowed to make use of at most 2 different letters

Then the number of ways will be : [tex]^{4} C_{2}[/tex] = 6 ways

now considering the length of the Finite strings

The number of strings that use no more than two different letters

Answer:

20th person

Step-by-step explanation:

Before proceeding into problem,assume that you don't know anyone else's birthday, and that birthdays are uniformly distributed throughout a 365 day year.

The probability, p(n), of winning a prize when you are the nth person is line is:

(probability that none of the first n−1 people share a birthday)*( probability that you share a birthday with one of the first n−1 people)

So,The first person can't have the same birthday as anyone less by themselves, so lets look at the second person. At the point where we add the second person there is a 364/365 chance of them not sharing a birthday with the previous person. When we add the 3rd person there is there is a 363/365 chance of them not sharing a birthday and so on such that the (n-1)th person when added has a probability of not forming a share of (365 -n -2)/365. We can multiply these together to get the probability that none of first (n-1) people share their birthday.

Therefore the position in line that has highest chance of winning is 20th.

We want to see which position has the largest probability of winning the prize. We will find that the 18th person has the largest probability of winning.

We know that a person only will win the prize if that person has the same birthday that some in front of him/her.

So, the probability that the n-th person wins the prize is given by:

(probability that none of the persons in front share a birthday)*(probability of sharing a birthday with some of the n - 1 people in front).

Let's find the first one.

The first person can have a birthday in any of the 365 days.

The second person must not have the same birthday, so there are 364 options remaining.

The probability of this is just

p₂ = 364/365

For the third person, we have the same thing, this time, 363 remaining options:

p₃ = 363/365

For the (n - 1) person the probability is:

pₙ₋₁ =  (365 - n + 2)/365

And the n-th person must share a birthday with some of the n persons in front of him, so there are (n - 1) options to choose, so the probability is:

pₙ = (n - 1)/365

Then, the joint probability is:

P = p₂*p₃*...*pₙ

[tex]P = \frac{364*363*...*(365 - n + 2)*(n - 1)}{365^{n-1}}[/tex]

Now we have the equation, we just need to solve it for n such that we maximize the value of P in the range n ∈ [1, 50]

This is actually a really hard thing to find, but what you can notice, is that each time that n increases by 1, the denominator increases 365 times.

While the numerator increases by a factor:

(365 - n - 1)*n/(n - 1)

So we need to find the value of n such that the thing above is equal or smaller than 365.

Let's solve:

(365 - n - 1)*n/(n - 1) = 365

(365 - n - 1)*n = 365*n - 365

364*n - n^2 - 365*n + 365 = 0

-n^2 - n + 365 = 0

This is just a quadratic equation, the solutions are:

[tex]n = \frac{1 \pm \sqrt{1 + 4*365} }{-2}[/tex]

We only care for the positive solution, so we take:

[tex]n = \frac{1 - \sqrt{1 + 4*365} }{-2} = 18.6[/tex]

So, for the 19th person, the probability of winning will be smaller than for the 18th person, this happens because the numerator increased by a smaller factor than the denominator.

This means that the 18 person has the largest probability of winning.

Answer:

y = - (1/2) x + 1

Step-by-step explanation:

The given equation of the line is:

2 x - y - 7 = 0

solving for y gives:

2 x - 7 = y

so y = 2 x - 7

where the slope is "2", which is fundamental to know in order to construct a perpendicular line to it by using the "opposite of the reciprocal" of the given slope.

So in our case, the slope of the perpendicular line must be:  "- 1 / 2"  (negative one half).

now we can build the equation of the new line, using this slope and requesting the point (4, -1) to be in it:

y = - (1/2) x + b

-1 = - (1/2) (4) + b

-1 = - 2 + b

solve for b:

b = 2 - 1 = 1

Then the equation of the perpendicular line is:

y = - (1/2) x + 1

y= -1/2 x+1

2x-y-7=0

2x-7=y

Answer:the last one

Step-by-step explanation:

Factor out 1/n⁴, and distribute the sum over each term:

[tex]\displaystyle\sum_{i=1}^n\frac{2i^3-3i}{n^4}=\frac1{n^4}\sum_{i=1}^n(2i^3-3i)[/tex]

[tex]\displaystyle\sum_{i=1}^n\frac{2i^3-3i}{n^4}=\frac2{n^4}\sum_{i=1}^ni^3-\frac3{n^4}\sum_{i=1}^ni[/tex]

Recall the following formulas:

[tex]\displaystyle\sum_{i=1}^ni=\frac{n(n+1)}2[/tex]

[tex]\displaystyle\sum_{i=1}^ni^3=\frac{n^2(n+1)^2}4[/tex]

So we have

[tex]\displaystyle\sum_{i=1}^n\frac{2i^3-3i}{n^4}=\frac{n^2(n+1)^2}{2n^4}-\frac{3n(n+1)}{2n^4}=\boxed{\dfrac{(n+1)(n^2+n-3)}{2n^3}}[/tex]
