Let f(x) = |x|, ????(x) = 2f(x), and h(x) = 1 / 2 f(x) for any real number x.
SashulF [63]

Answer:

g(x) = 2|x|

h(x) = \frac{1}{2}|x|

Step-by-step explanation:

If you have g(x)=2f(x) and h(x)=\frac{1}{2}f(x), you can rewrite the expressions in terms of |x| as the following:

- For g(x)=2f(x) you have:

g(x) = 2|x|

-For h(x)=\frac{1}{2}f(x), you have:

h(x) = \frac{1}{2}|x|

​ Assume the trait for brown eyes is completely dominant to blue eyes and this trait is controlled by a single gene. If 400 peop
Alekssandra [29.7K]

Answer:

3200 people

Step-by-step explanation:

p = The frequency of the dominant gene

q = The frequency of the recessive gene

q^2=\frac{400}{10000}\\\Rightarrow q^2=0.04\\\Rightarrow q=0.2

p+q = 1

⇒p = 1-q

⇒p = 1-0.2

⇒p = 0.8

Hardy-Weinberg formula

p² + 2pq + q² = 1

Now for heterozygous trait

2pq = 2×0.8×0.2 = 0.32

Multiplying with the population

0.32×10000 = 3200

∴ 3200 people would be expected to be heterozygous for this trait.
