Answer:
(5,1)
Step-by-step explanation:
For the x coordinate, F is between 4 and 6, so it is 5. For the Y coordinate, it is between 0(the origin) and 2, which means it is 1. Combining those, the answer is (5,1)
Hello,
when x->+infinity , y-->+infinity
when x->-infinity, y->+infinity
Answer:
Step-by-step explanation:
x² - 6x + 7 = 0
x² - 6x = -7
Find 6÷ 2 = 3. Find 3² = 9. Now add 9 to both side
x² - 6x + 9 = -7 +9
x² - 2*x*3 + 3² = 2
(x - 3)² = 2
Solution
x - 3 = √2
x - 3 = ± 1.41
x = 1.41 + 3 ; x = -1.41 + 3
x = 4.41 ; x = 1.59

Calculate Jean's rate
----------------------------------------------
Jean takes 8 hours to fill the pool.
So in 1 hour, she can fill 1/8 of the pool
----------------------------------------------
Calculate Mark's rate
----------------------------------------------
Mark takes 12 hours to fill the pool.
So in 1 hour, he can fill 1/12 of the pool.
----------------------------------------------
Calculate their rate if they work together
----------------------------------------------
Jean = 1/8
Mark = 1/12
1/8 + 1/12 = 3/24 + 2/24 = 5/24
They will fill 5/24 of the pool in 1 hour
----------------------------------------------
Find number of hours needed to fill up the pool
----------------------------------------------
I hour = 5/24 of the pool
1 ÷ 5/24 hour = 5/24 ÷ 5/24 of the pool
24/5 hour = Whole pool
Whole pool = 24/5 hours
Whole pool = 4 4/5 hours or 4.8 hours
----------------------------------------------
Ans: The supervisor is not correct, it will take only 4.8 hours if both of them work together.

ANSWER
EXPLANATION
The first polynomial is
The second polynomial is
If we add the two polynomials we obtain,
Next we group like terms to obtain,
We simplify the to obtain,
This is the sum of the two polynomials in descending powers of
Descending means from the highest power to the least.
