Answer:

xy+y^2+2x+4y+4

Step-by-step explanation:

simplify by multiplying variable in the first parentheses set with the ones in the second parentheses set:

(x+y+2)(y+2)

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

=xy+2x+y^2+2y+2y+4

=xy+y^2+2x+4y+4

hope this helps!

Kim is a medical supplies salesperson. Each month she receives a 5% commission on all her sales of medical supplies up to $20,00
lions [1.4K]

Answer: her sales for the month of May is $55000

Step-by-step explanation:

Let x represent her total sales for the month of May.

Each month she receives a 5% commission on all her sales of medical supplies up to $20,000. This means that for her first sales worth $20000, she earns a commission of

5/100 × 20000 = 1000

She also earns 8.5% on her total sales over $20,000. This means that for sales over $20000, she earns

8.5/100(x - 20000) = 0.085x - 1700

Her total commission for May was $3,975. The expression becomes

1000 + 0.085x - 1700 = 3975

0.085x = 3975 + 1700 - 1000

0.085x = 4675

x = 4675/0.085

x = 55000

PLEASE HELP ME ASAP!!!!!!!!!!!!!!!!!!!!!!!!! 3) This problem is called the Collatz Conjecture and is an unproven statement in ma
Aneli [31]

The set of numbers in the Collatz Conjecture are 1, 4, 2, 1, 4, 2, 1, 4, 2....

<h3>How to generate the numbers in the Collatz Conjecture</h3>

To start with, we make use of the following starting point:

Starting point = 1

The rule is given as:

  • If the last number is odd, multiply it by 3 and add 1.
  • If the last number is even, divide the number by 2.

1 is an odd number.

So, we use the first rule

So, we have:

1 * 3 + 1 = 4

4 is an even number.

So, we use the second rule

So, we have:

4/2 = 2

So, the first three numbers in the Collatz Conjecture are:

1, 4, 2

Using the given rules, we have:

1, 4, 2, 1, 4, 2, 1, 4, 2....

The above means that there is only one set of repeating numbers in the Collatz Conjecture.

Hence, the set of numbers in the Collatz Conjecture are 1, 4, 2, 1, 4, 2, 1, 4, 2....

<h3>Fibonacci sequence</h3>

The first and the second numbers are given as:

First = 2

Second = 5

The current term of a Fibonacci sequence is the sum of the previous two terms.

Using the above rule, the first 10 terms are:

2, 5, 7, 12, 19, 31, 50, 81, 131, 212

<h3>The sum of the first 10 terms of the new sequence</h3>

We have:

2, 5, 7, 12, 19, 31, 50, 81, 131, 212

Add the terms

Sum = 2+ 5+ 7+ 12+ 19+31+50+81+131+212

Evaluate

Sum = 550

Hence, the sum of the first 10 terms of the new sequence is 550

ziro4ka [17]

Answer:

The answer is "12 times, a die was rolled. Identify the complete possibilities to roll exactly 6".

Step-by-step explanation:

Using formula:

P(X=K)=\binom{N}{K} P^{K}  a^{N-K}

So the value is P(X=6)

The sum of two rational number is minus 4 by know if one of them is 13 by 6 them find the other ​
attashe74 [19]

Answer:

the sum of two rational number is minus 4 by know if one of them is 13 by 6 them find the other ​

Step-by-step explanation:

let the second rational no. be x

then a/q,

13/6 + x = -4/9

x = -4/9 - 13/6

x = (-16 - 78)/36

x = - 94/36 or -47/18

x = -2.61111
