E/P 14)The equation 2x²+ 4kx - 5k = 0, where k is a constant, has no real roots.

aalyn [17]

Step-by-step explanation:

Discriminant = 16k² - 4(2)(-5k)

Since 16k² + 40k < 0, 2k² + 5k < 0, k(2k + 5) < 0.

Therefore -5/2 < k < 0.

Please help me with pythagoras.

lana [24]

Answer:

(q)

$cb \: = \sqrt{4 {}^{2} + {3}^{2} }$

$cb = 5$

$q = \sqrt{ {13}^{2} - {5}^{2} }$

$q = 12$

(r)

$cb = \sqrt{ {13}^{2} - {5}^{2} }$

$cb = 12$

$r = \sqrt{12 {}^{2} - 5 {}^{2} }$

$r = \sqrt{119}$

$r = 10.91$

(s)

$ab = \sqrt{20 {}^{2} - 16 {}^{2} }$

$ab = 12$

$s = \sqrt{12 {}^{2} + 8 {}^{2} }$

$s = 4 \sqrt{13}$

$s = 14.42$
