The interpretations of the functions for the new garden plots are as follows:

A(x) = x^2 represents the area of the original garden plot. Now, let's take a look at the other three functions:

Garden B: A(x) = x^2 + 8x + 7

This function adds 8x and 7 to the original garden plot area. This means that the garden will be wider and longer than the original plot. The 8x term indicates that the garden will be extended by 8 feet in length, and the constant term 7 indicates that the garden will be extended by 7 feet in width. Therefore, Garden B will be bigger than the original garden.

Garden C: A(x) = x^2 - 9

This function subtracts 9 from the original garden plot area. This means that the garden will be shorter and narrower than the original plot. The -9 term indicates that the garden will be reduced by 9 feet in width. Therefore, Garden C will be smaller than the original garden.

Garden D: A(x) = x^2 - 13x + 36

This function subtracts 13x and adds 36 to the original garden plot area. This means that the garden will be shorter and wider than the original plot. The -13x term indicates that the garden will be reduced by 13 feet in length, and the constant term 36 indicates that the garden will be extended by 36 feet in width. Therefore, Garden D may be bigger or smaller than the original garden, depending on the specific value of x used in the function.

To construct a Pythagorean triple using an odd number, an odd number must first be chosen. Here 5, 12, and 13 form a Pythagorean triple.

To generate Pythagorean triples using an odd number, follow these steps:

Choose any odd number, say n.

Calculate (n^2-1)/2 and n. These two numbers will form a Pythagorean triple.

Check if the numbers obtained in step 2 are indeed a Pythagorean triple. The two numbers should satisfy the Pythagorean theorem, i.e., a^2 + b^2 = c^2, where a and b are the smaller numbers, and c is the largest number.

If the numbers in step 2 do not form a Pythagorean triple, choose a different odd number and repeat the process.

For example, let's choose the odd number 5:

(n^2-1)/2 = (5^2-1)/2 = 12

n = 5

Now, we can check if 5, 12, and 13 form a Pythagorean triple:

5^2 + 12^2 = 13^2

25 + 144 = 169

Therefore, 5, 12, and 13 form a Pythagorean triple.

We can repeat this process with different odd numbers to generate more Pythagorean triples.

Answer:

you can only rent the ski boat for about 3 hours.

Step-by-step explanation:

if you cant spend no more than $150

you need to see how much u can spend within hours.

so you would have to see what 35 can be multiplied to get to 150.

obviously no number multiplied by 35 will get you 150, but if you multiply 35 x 4, you will get 140, which is close enough, yet still you don't have enough for a full 4 hours.

Then you have to consider that you still need to pay $20 just to rent the ski boat alone.

So that will take away from the money you have.

when you subtract 20 from 140, you will still not have enough money for 4 whole hours, therefore you will only have enough for 3 hours with the $ 120 you have left.

The probability that both her selections are vegetarian is 1/14.

What is probability?

Probability is a branch of mathematics that deals with the study of random events or processes. It is the measure of the likelihood or chance of an event or outcome occurring, expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

There are 15 toppings in total, so there are 15 ways for the customer to choose her first topping.

If the first topping is vegetarian, there are 8 vegetarian toppings left out of 14 total toppings, so there are 8 ways for the customer to choose a second vegetarian topping.

If the first topping is non-vegetarian, there are 7 vegetarian toppings left out of 14 total toppings, so there are 7 ways for the customer to choose a second vegetarian topping.

Therefore, the total number of ways for the customer to choose two vegetarian toppings is 8 + 7 = 15.

The total number of ways for the customer to choose two toppings is the number of ways to choose the first topping (15) multiplied by the number of ways to choose the second topping after the first topping has been chosen (14).

Therefore, the total number of ways for the customer to choose two toppings is 15 x 14 = 210.

The probability of choosing two vegetarian toppings is the number of ways to choose two vegetarian toppings (15) divided by the total number of ways to choose two toppings (210):

P(choosing two vegetarian toppings) = 15/210

Simplifying the fraction by dividing the numerator and denominator by 15, we get:

P(choosing two vegetarian toppings) = 1/14

Therefore, the probability that both her selections are vegetarian is 1/14.

Using the concept of similar triangles, we were able to find the height of the tree given the man's height, distance from the tree, and distance from the steak. The tree is approximately 6.25 feet tall.

We can use similar triangles to find the height of the tree. Let x be the height of the tree in feet. Then, we have:

x / (x+5) = 6 / 30

Cross-multiplying, we get:

30x = 6(x+5)

Expanding and simplifying, we get:

30x = 6x + 30

24x = 30

x = 1.25

Therefore, the tree is 1.25 + 5 = 6.25 feet tall.

In conclusion, the height of a tree can be determined using similar triangles. By setting up the proportion of the tree's height to its distance from a person, and using cross-multiplication, the height can be solved for. The tree is 6.25 feet tall.

When a same bottle of ethanol starts at 10°C and absorbs 2500 J of heat, its final temperature is 45°C.

This problem can be solved using the specific heat capacity formula, which is expressed as

Q= mc ∆T

where Q is the amount of heat absorbed, m is the mass, c is the specific heat capacity and ∆T is the change in temperature.

The initial temperature of ethanol = 10°C

The amount of heat absorbed = 2500 J

We need to find the final temperature of ethanol. Let's use the specific heat formula to solve for the final temperature.

Q=mc∆T

where, Q = amount of heat absorbed = 2500 J

c = specific heat of ethanol = 2.44 J/g°C

∆T = change in temperature = final

temperature - initial temperature m = mass of ethanol

We need to calculate the mass of ethanol to use this formula.

Let's assume that the mass of ethanol is

100 g.m = 100 gQ = mc∆T2500 = 100 × 2.44 × ∆T ∆T = 10.25°C

Now, let's add this change in temperature to the initial temperature to find the final temperature.

Final temperature = Initial temperature + ∆T Final temperature = 10°C + 10.25°C

Final temperature = 20.25°C + 24.75°C

The probability that a randomly chosen painting from the 20th century is British is B/T.

It is determined by the ratio of British paintings to total paintings from the 20th century. If we assume that the total number of 20th century paintings is represented by T and the number of British paintings is represented by B, then the probability of a randomly chosen painting from the 20th century being British is B/T.

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
