1. What is the temperature when a cricket chirps 52 times in 14 seconds? [tex]\(\square\)[/tex]

2. Write an equation that defines [tex] F [/tex] as a function of [tex] n [/tex]. [tex]\(\square\)[/tex]

3. How many chirps would we expect to hear in 14 seconds when it is 60 degrees Fahrenheit? [tex]\(\square\)[/tex]

Options:

- 12 degrees Fahrenheit
- 66 degrees Fahrenheit
- 92 degrees Fahrenheit
- [tex] F = n + 40 [/tex]
- [tex] F = n - 40 [/tex]
- [tex] n = F + 40 [/tex]
- [tex] n = F - 40 [/tex]
- 20 chirps
- 74 chirps
- 100 chirps

Answer :

Sure, let's solve each part of the question step by step:

1. What is the temperature when a cricket chirps 52 times in 14 seconds?

To find the temperature, we use the formula where [tex]\( F \)[/tex], the temperature in degrees Fahrenheit, is a function of [tex]\( n \)[/tex], the number of chirps in 14 seconds.

The equation is: [tex]\( F = n + 40 \)[/tex].

Given that the cricket chirps 52 times, let's substitute [tex]\( n = 52 \)[/tex] into the equation:

[tex]\( F = 52 + 40 = 92 \)[/tex].

Therefore, the temperature is 92 degrees Fahrenheit.

2. Write an equation that defines [tex]\( F \)[/tex] as a function of [tex]\( n \)[/tex].

From the relationship provided, the temperature [tex]\( F \)[/tex] is related to the number of chirps [tex]\( n \)[/tex] by the formula:

[tex]\( F = n + 40 \)[/tex].

So, the equation that defines [tex]\( F \)[/tex] as a function of [tex]\( n \)[/tex] is [tex]\( F = n + 40 \)[/tex].

3. How many chirps would we expect to hear in 14 seconds when it is 60 degrees Fahrenheit?

Here, we need to find [tex]\( n \)[/tex] given that [tex]\( F = 60 \)[/tex].

We use the formula: [tex]\( F = n + 40 \)[/tex].

Rearranging the formula to solve for [tex]\( n \)[/tex], we get:

[tex]\( n = F - 40 \)[/tex].

Substitute [tex]\( F = 60 \)[/tex]:

[tex]\( n = 60 - 40 = 20 \)[/tex].

Therefore, we would expect to hear 20 chirps in 14 seconds when it is 60 degrees Fahrenheit.

4. Write an equation that defines [tex]\( n \)[/tex] as a function of [tex]\( F \)[/tex].

Based on the equation we used to find chirps given a temperature, we have:

[tex]\( n = F - 40 \)[/tex].

So, the equation that defines [tex]\( n \)[/tex] as a function of [tex]\( F \)[/tex] is [tex]\( n = F - 40 \)[/tex].
