Answer:

producers

Explanation:

All the energy comes from the sun. a small amount of sunlight energy is trapped by green plants and used in photosynthesis to form organic materials in plants that are sources of food to the rest of the animals. Animals get this energy when they feed on plants directly like the herbivores or indirectly like the carnivores.

why must the symbol +- be written in front of the radical to write the inverse of the function f(x)=x^2?

oee [108]

Here is why:

When we solve for the inverse function (see the particular step below; when we have: " y² = x " ;

We take the "square root" of EACH SIDE of the equation; to isolate "y" as a single variable on one side of the equation;

→ √(y²) = √x ;

→ |y| = |√x| ;

y = ± √x ;

Because when we take the square root — or any "even root", for that matter—we have two solutions: of a variable, we have TWO SOLUTIONS: a positive value; and a negative values;

→ since: 1) a "negative value"; multiplied by a "negative value" ; equals a "positive value" ;
→ and as such: a "negative value" ;
multiplied by that same "negative value" ;
{that is: a "negative value", "squared (i.e "raised to the power of "2"} ; ,
→ results in a positive value ;
→ and since:
2) a "postive value"; multiplied by a positive value" ; equals a "positive value" ;
→ and as such: a "positive value" ;
multiplied by that same "positive value" ;
{that is: a "positive value", "squared (i.e "raised to the power of "2"} ; ,
→ results in a "positive value";
→ and since:
3) any given integer, in it "positive value", squared (i.e. raised to the power of "2"); results in a "positive value" ;
→and since:
4) that same aforementioned integer; in its "negative value" form, squared (i.e. raised to the power of "2"); results in that same aforementioned "positive value".
________________________________________________________
Note the following:
________________________________________________________

"Given the function: "f(x) = x² " ; Find the "inverse function" .

Let "y" = f(x) " ;

and write as: " f(x) = y = x² " ;

→ " y = x² " ;

→ Now, rewrite the equation; replacing the "y" with "x" ;
and replacing the "x" with "y" ;

→ " x = y² " ;

Now, rewrite the question; isolating "y" as a single variable;
with no coefficient (save for the "implied coefficient of "1" ) ;

→ " x = y² " ;

↔ " y² = x ;

Now, take the square root of EACH SIDE of the equation;
to isolate "y" on one side of the equation;

→ √(y²) = √x ;

→ |y| = |√x| ;

→ y = ± <span>√x .
</span>
Replace the "y" with " f ⁻¹(x)" ; to indicate that this the "inverse function" ;

and write the "inverse function" :

→ " f ⁻¹(x) = ± √x " ;

In humans the presence of chin and cheek dimples is dominant to the absence of dimples, and the ability to taste the compound PT

nikklg [1K]

Answer:

The frequency of undimpled tasters is 0.136.

Explanation:

The Hardy-Weinberg law illustrated all the probable genotypes for a gene with two alleles. The binomial expansion signifying this is, p2+2pq+q2 = 1.0

Here, p2 is the proportion of homozygous dominant individuals, q2 refers to the proportion of homozygous recessive individuals, and 2pq is the proportion of heterozygotes.

Thus, on the basis of the given data, the frequencies for dimples phenotypes are:

The frequency of homozygous dominant allele carrying individuals (DD) = 0.62 * 0.62 = 0.3844

The frequency of heterozygous allele carrying individuals (Dd) = 2 * 0.62 * 0.38 = 0.4712

The frequency of homozygous recessive allele carrying individuals (dd) = 0.38 * 0.38 = 0.1444

Thus, from the above frequencies, the frequency of individuals with dimples (DD and Dd) = 0.3844 + 0.4712 = 0.8556

The frequency of individuals without dimples (dd) = 0.1444.

The frequencies for tasting phenotypes:

The frequency of homozygous dominant allele carrying individuals (TT) = 0.76 * 0.76 = 0.5776

The frequency of heterozygous allele carrying individuals (Tt) = 2 * 0.76 * 0.24 = 0.3648

The frequency of homozygous recessive allele carrying individuals (tt) = 0.24 * 0.24 = 0.0576

Thus, from the above frequencies:

The frequency of individuals with taste for PTC (TT and Tt) = 0.5776 + 0.1824 = 0.944

The frequency of individual without taste for PTC (tt) = 0.0576

As it is a dominant mode of inheritance the genotype of undimpled tasters is either ddTt or ddTT.

The frequency of taster individuals will be TT + Tt = 0.5776 + 0.3648 = 0.9424

Now, the expected frequency of undimpled tasters will be the product of frequency of dimpled and frequency of tasters = 0.144 * 0.9424 = 0.1357.

Therefore, the frequency of the undimpled tasters is 0.136.
