Answer:
4 right angles
Step-by-step explanation:
a straight light intersects another straight line= creating 4 right angles
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:
0.0009
Step-by-step explanation:
9*10⁻⁴ = 0.0009
no because if your rounding 736,400 it will be 740,000 if its 4 or less you let it rest if its 5 or more it rises
-8.9n+7.5
would be your answer
