The Punnett square is a diagram divided into squares that is used to determine genotypes.

The question is incomplete, as the required details such as the characters that represent the plant heights and the flower colors are not given.

So, I will give a general explanation instead.

Assume the plants that are crossed are represented as: TT and Tt.

The possible genotypes would be TT, TT,Tt and Tt

In the above list of genotypes, genotype T is dominant over genotype t

See attachment for an illustration of the Punnett square.

Answer:

Area = 2500 square feet is the largest area enclosed

Step-by-step explanation:

A rectangular piece of land borders a wall. The land is to be enclosed and to be into divided 3 equal plots with 200 feet of fencing

Let x be the length of each box and y be the width of the box

Perimeter of the box= 3(length ) + 4(width)

$200=3x+4y$

solve for y

$200=3x+4y$

$200-3x=4y$

divide both sides by 4

$y=50-\frac{3x}{4}$

Area of the rectangle = length times width

$Area = 3x \cdot y$

$Area = 3x \cdot (50-\frac{3x}{4})$

$A=150x-\frac{9x^2}{4}$

Now take derivative

$A'=150-\frac{9x}{2}$

Set it =0 and solve for x

$0=150-\frac{9x}{2}$

$150=\frac{9x}{2}$

multiply both sides by 2/9

$x=\frac{100}{3}$

$A''=-\frac{9}{2}$

For any value of x, second derivative is negative

So maximum at x= 100/3

$A=150x-\frac{9x^2}{4}$ , replace the value of x

$A=150(\frac{100}{3})-\frac{9(\frac{100}{3})^2}{4})$

Area = 2500 square feet is the largest area enclosed

Please could someone explain how to do question 2)a) (ii)

KonstantinChe [14]

Answer:

15 kilometres

Step-by-step explanation:

Based on the wording of your question, I am assuming you already know that Paul ran 250 metres every 1 minute, and that the ratio is 250:1. To get the second part of the answer, convert metres to kilometres. 0.001*250= 0.25. Paul ran 0.25 kilometres per minute. The ratio of kilometres per minute is 0.25:1. Next, convert minutes to hours. Multiply the entire ratio by 60, as there are 60 minutes in an hour. The ratio of kilometeres per minute is 15:60, and the ratio of kilometres per hour is 15:1, meaning Paul ran 15 kilometres in one hour.

What is the range of the function shown on the graph?

never [62]

Answer:

$y \in \{\space \mathbb R \space| -6 < y < \infty\}$

Step-by-step explanation:

We can see from the graph that $y$ can't be lesser than $-6$ and $y$ extends unendlessly in the positive direction.
