Answer:
0.985
Step-by-step explanation:
Ok. So what I did was I chose a number that would be easy to manipulate The number I chose was 10, I then multiplied it by 4 to get 40, then subtracted 3 to get 37 - that was the first part of the question. The second part wanted me to take the same number, multiply it by 3 and then add 7. So 10 multiplied by 3 is of course 30 and then you just add 7 to get 37. Hey look! Its a match! I hope this helps.
P.S. - If you think I did a good job I would love it if you went to my YouTube channel to see if I can help you more there. Here is the link: https://www.youtube.com/channel/UCG0zQcSsxZ2mu-OnZRdI2-Q . I hope to see you there!
If the first two terms are 1 and 1, then what is the tenth term?
Answer:
The 10th term will be 55
Explanation:
In the Fibonacci Sequence, we add the previous digits to get the next digit. So, here 1st term is 1.
First term= 1
Second term = 0+1= 1
Third term= 1+1=2
Fourth term= 1+2= 3
Fifth term= 2+3= 5
Sixth term= 3+5= 8
Seventh term= 5+8 = 13
Eighth term= 8+13= 21
Ninth term= 13+21= 34
Tenth term= 21+34 = 55
So, the 10th term is 55.
Use the reciprocal method. the first term is really 4 divided by 3/4. which is also the same as 4 multiplied by 4/3. that number is 16/3 of course. you then find a common denominator between the 2 terms. 16/3 and 3/2 can both have the denominator 6. The first term gets changed to 32/6 and the second can be changed to 9/6 and when 32/6 - 9/6 is done, it comes out to 23/6
23/6
Take the complex zero 1+i. There must be another zero 1-i to balance it, so we have the factors (x-1-i)(x-1+i)=x²-2x+1+1=x²-2x+2.
So the polynomial is (x+3)(x²-2x+2)=x³-2x²+2x+3x²-6x+6=x³+x²-4x+6, option D.
