1.6 × 10 to the negative sixth power "10 -6".
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>.
Answer:
44
Step-by-step explanation:
Answer:
B, because thats dividing, which equals 3. for the answer A, did you mean 15*5?
Step-by-step explanation:
Answer:
27 units²
Step-by-step explanation:
Cut the figure into a 8 by 3 rectangle and triangle.
The area of the rectangle is 8*3 or 24
The area of the triangle is 3 using the formula 1/2bh where the base and height are 3.
Adding those 2 areas together 24+3 will equal 27
