Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Often, it is impossible to determine which two alleles of a gene are present within an organism's chromosomes based solely on the outward appearance of that organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

Determine which functions have two real number zeros by calculating the discriminant, b2 – 4ac. Check all that apply. Please ans
valkas [14]
F(x) = x^2 + 6x + 8
= b^2 - 4ac
= (6)^2 - 4(1)(8)
= 36 - 4(8)
= 36 - 32
= 4

g(x) = x2 + 4x + 8
= b^2 - 4ac
= (4)^2 - 4(1)(8)
= 16 - 4(8)
= 16 - 32
= -16

h(x) = x2 – 12x + 32
= b^2 - 4ac
= (-12)^2 - 4(1)(32)
= 144 - 4(32)
= 144 - 128
= 16

k(x) = x2 + 4x – 1

= (4)^2 - 4(1)(-1)
= 16 - 4(-1)
= 16 + 4
= 20

p(x) = 5x2 + 5x + 4
= b^2 - 4ac
= (5)^2 - 4(5)(4)
= 25 - 4(20)
= 25 - 80
= -55

t(x) = x2 – 2x – 15
= b^2 - 4ac
= (-2)^2 - 4(1)(-15)
= 4 - 4(-15)
= 4 + 60
= 64

The position of a particle (in inches) moving along the x-axis after t seconds have elapsed is given by the following equation:
SVEN [57.7K]

Answer:

a = 132 m/s^2

Explanation:

f(t) = t^4 − 2t^3 − 6t^2 + 9t

v = f'(t) = 4t^3 - 6t^2 - 12t + 9

a = f''(t) = 12t^2 - 12t -12

Substitute t = 4 seconds into the equation for a:

a = 12(16) -12(4) -12 = 132 m/s^2
