Write a polynomial function of least degree with integral coefficients that has the given zeros.
densk [106]
The zeroes are
0, -5, 3 + i (and its conjugate)

The factors are
x (x + 5) (x - (3 + i)) (x - (3 - i))
Expanding...
(x² + 5x)((x - 3) - i) ((x - 3) + i)
(x² + 5x)((x - 3)² - i²)
(x² + 5x)(x² - 6x + 9 - (-1))
(x² + 5x)(x² - 6x + 10)
x⁴ - 6x³ + 10x² + 5x³ - 30x² + 50x
x⁴ - x³ - 20x² + 50x

Pls help with this problem
madam [21]

Step-by-step explanation:

every triangle inscribed into a circle with the baseline being a diameter of the circle must be a right-angled triangle.

therefore,

angle XVY = 90°.

for VY we can use Pythagoras

c² = a² + b²

with c being the Hypotenuse (the line opposite of the 90° angle, in our case XY).

XY = 2×ZY = 2×17 = 34.

so,

34² = 30² + VY²

VY² = 34² - 30² = 1156 - 900 = 256

VY = 16

The area of a rectangular concrete patio is 70 square meters. the perimeter is 34 meters. what are the dimensions of the patio?
Finger [1]
A = L * W
A = 70

70 = L * W

P = 2(L + W)
P = 34

34 = 2(L + W)
34/2 = L + W
17 = L + W
17 - W = L

70 = L * W
L = 17 - W

70 = W(17 - W)
70 = -W^2 + 17W
W^2 - 17W + 70 = 0
(W - 10)(W - 7) = 0

W - 10 = 0        L = 17 - 10
W = 10              L = 7

W - 7 = 0          L = 17 - 7
W = 7               L = 10

so either the width is 10 meters and the length is 7 meters OR the width is 7 meters and the length is 10 meters
