Write a polynomial in standard form with given Zeroes given zeroes are 5 and 3+2i

1 answer:

4 0

Required potynomial = (x -5)(x - 3 - 2i)(x - 3 + 2i) = (x - 5)(x^2 - 6x + 13) = x^3 - 6x^2 + 13x - 5x^2 + 30x - 65 = x^3 - 11x^2 + 43x - 65

AnnZ [28]

Answer:

z = -5

Step-by-step explanation:

3(0.7z + 2.8) = 7(1.5z + 7.2)

2.1z + 8.4 = 10.5z + 50.4

2.1z - 10.5z = 50.4 - 8.4

-8.4z = 42

z = 42/(-8.4)

z = -5

In ΔSTU, u = 84 inches, s = 13 inches and ∠T=165°. Find the length of t, to the nearest inch.

Mariana [72]

Answer:

Step-by-step explanation:

I used the law of cosines: $t^{2} =s^{2} +u^{2} -2tu cos (t)$

Let plug the numbers in : t^2= $13^{2} +84^{2} -2(13)(84)cos (165)$ which approx is 97 to the nearest inch.
