The general form of a polynomial is: x² + bx + c = 0. Substituting the roots,
3² + b(3) + c = 0
3b + c = -9 --> eqn 1
(5 + √5)² + (5 +√5)(b) + c = 0
(5+√5)b + c = -30-10√5 --> eqn 2
Solving both equations simultaneously by subtracting eqn 2 from eqn 1,
(-2 - √5)b = 21 + 10√5
b = -8 - √5
Using eqn 1,
3(-8 - √5) + c = -9
-24 - 3√5 + c = -9
c = -9 + 24 + 3√5
c = 15 + 3√5
Hence, the polynomial is: <em>f(x) = x² + (-8 - √5)x + (15 + 3√5)</em>.
For the $3.75 it would cost $281.25 and for the $3.95 it would cost $296.25
Hope this helps!
Answer:
7 Baskets
Step-by-step explanation:
Kira will need 7 baskets. To find this you divide 255 by 38 to get 6.7.052632. Since you cannot split a basket you will need to round to the nearest whole number which is 7.
Answer:
First, this table is a function because it has no repeating input values
Second, it is increasing in both the x and y
third, since it is increasing in x and y it is a positive correlation( I dont know if you have learned that yet)
Fourth, the output increases by 4 each time the input increases by 1
Step-by-step explanation:
Basically 3 : horizontally, diagonally, and vertically.
