Answer:
10x^4-15x^3+17x^2-13x+17
Step-by-step explanation:
P-2Q
Replace P and Q with the given values,
4x^4-3x^3+x^2-5x+11-(2(-3x^4+6x^3-8x^2+4x-3)
4x^4-3x^3+x^2-5x+11-(-6x^4+12x^3-16x^2+8x-6)
4x^4-3x^3+x^2-5x+11+6x^4-12x^3+16x^2-8x+6
10x^4-15x^3+17x^2-13x+17
Answer:
x = 5√3; y = 5
Step-by-step explanation:
Finding y: The sine function links the 30° angle, the 10 unit hypotenuse and the side opposite the angle, y:
sin 30° = 1/2 = y/10
Solve the equation of ratios
1 y
-- = ----- using cross-multiplication first: 2y = 10 → y = 5
2 10
We can now find x either by using a similar approach and the cosine function or by using the Pythagorean Theorem:
x² + y² = 10² = 100 → x² = 100 - y² = 100 - 5² = 75
If x² = 75, then x = ±√75 = ± (√25)·(√3) → ±5√3
Since lengths are always positive, take x = 5√3 as the answer.
Okay so just put the 4 in for x
and multiply
