b. 3 - *sqrt* 7 , 6 + *sqrt* 2
c. 7 + *sqrt* 3 , 2 - *sqrt* 6
d. 3 + *sqrt* 7 , 6 - *sqrt* 2

Answers

Answer 1
Answer:

Answer:

option: A

Step-by-step explanation:

" if for a polynomial with rational coefficients has irrational roots then these irrational roots will always appear in pair " .

we are given that 7+√(3) and 2-√(6) are two roots of a polynomial equation with rational coefficients, then it's complex conjugate is also a root of this polynomial equation i.e.7-√(3) ' and '  2+√(6) ' are also roots of this polynomial equation.

Hence, option A is correct.


Answer 2
Answer: If the coefficients of a polynomial equation are rational, then the irrational roots have to come in conjugate pairs.
The conjugate of 7 +√ 3 is 7 - √ 3 and the conjugate of 2 - √ 6 is 2 + √ 6.
Answer:
A ) 7 - √ 3 ,  2 + √ 6

Emily is making bows using ribbon. She has two pieces of ribbon to use. One is 23 yards long. The other is 4 1/4 yards long. She need 1 5/6 yards of ribbon to make each bow. What is the greatest number of bows emily can make? Show your work

Answers

Answer:

14


Step-by-step explanation:

In total, Emily has  23+4(1)/(4)=27(1)/(4)=(109)/(4)  yards of ribbon.

Each bow requires  1(5)/(6)=(11)/(6)  yards of ribbon


To figure out, we divide total amount of ribbon by amount each bow needs:

Number of bows = ((109)/(4))/((11)/(6))=14.86


So the maximum number of "complete" bows Emily can make is 14

Final answer:

Emily has a total of 27 1/4 yards of ribbon. Each bow requires 1 5/6 yards, therefore Emily can make 14 bows with the ribbon she has.

Explanation:

To solve this problem, we first need to determine the total amount of ribbon that Emily has. She has one piece that is 23 yards long and another that is 4 1/4 yards long. To find the total, we add these two lengths together:

23 yards + 4 1/4 yards = 27 1/4 yards

Each bow Emily makes needs 1 5/6 yards of ribbon. To find out how many bows she can make, we divide the total amount of ribbon by the amount needed for each bow:

27 1/4 yards ÷ 1 5/6 yards = 14.6(around)

Since Emily cannot make a fraction of a bow, we round down to the nearest whole number. So, Emily can make 14 bows.

A six sided die, with sides numbered 1,2,3,4,5, and 6, is tossed. What is the probability of tossing a number less than 3

Answers

ok so probablit is
(desired outcomes)/(total possible outcomes)
ok so total possible is 6 since 6 numbers
less than 3 means all numbers less than 3 not including 3
there are 2 (1 and 2 are less than 3)
2=desired outcomes
6=total possible
2/6=1/3

probability is 1/3
2/6 reduced to simplest terms.... being 1/3 so your answer would be 1/3 hope i helped(1 and 2 are the only numbers less then 3 and since there are 6 sides the possibility is 2/6 but it probably wants it reduced, so the answer is 1/3... whenever you can reduce to simplest terms ALWAYS reduce...)

What is the pattern 3,3.3,3.63,3.993

Answers

Each number is the number before it multiplied by 1.1
And since it is multiplied, there is a common ratio and so it is a geometric sequence.
3 x 1.1 = 3.3
3.3 x 1.1 = 3.63
And it goes on.

Hope this helps :)
1.1 is multiplied to each result

Taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. Provide Taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1g(x)=2x^2+1

Answers

Answer:

f(x)=g(x) at x= 0 and x= 1 and not at x= 3.

Step-by-step explanation:

We have the functions, f(x)=2x+1 and g(x)=2x^2+1.

It is given that,

At x=0, x=1, and x=3, f(x)=g(x)

i.e. 2x+1=2x^2+1

i.e. 2x^2-2x=0

i.e. 2x(x-1)=0

i.e. x= 0 and (x-1)= 0

i.e. x= 0 and x= 1.

Also, after plotting the graphs of both the functions, we see their intersection point are (0,1) and (1,3).

Thus, we get that f(x)=g(x) at x= 0 and x= 1 and not at x= 3.
