Answer:
(c) P(x) = x^4 +3x^3 -10x^2 -30x
Step-by-step explanation:
If the polynomial has integer coefficients, its complex or radical roots come in conjugate pairs. That is, -√10 is also a root. The four roots mean the polynomial has degree 4. That eliminates all but answer choice C.
Each root 'a' gives rise to a factor (x -a), so the factored polynomial is ...
P(x) = (x -0)(x -(-3))(x -√10)(x -(-√10))
P(x) = x(x +3)(x² -10) = x(x³ +3x² -10x -10)
P(x) = x^4 +3x^3 -10x^2 -10x
Answer:
see explanation
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ) , then
A (- 1, - 17 ) → A' (- 1, 17 )
B (0, - 12 ) → B' (0, 12 )
C (- 5, - 11 ) → C' (- 5, 11 )
D (- 6, - 16 ) → D' (- 6, 16 )
7^2+18^2=49+324
49+324=373
19.31^2 would be your answer
The geometric figures without measurable quantity:
- A line is infinite and have no measurable length.
- A point is a zero dimensional.
- A ray is semi-infinite. It has a beginning but no end.
An angle and a line segment are measurable.
Answer:
B. Angle
D. Line segment.
D) 9 because 1.45 divided by 5 = 0.29
if you move to the hundredths place (9) and its not 2 because, 2 is in the tenths
