Answer:

<h3>dn = -7^n-1</h3>

Step-by-step explanation:

Given the sequence -1,-7,-49,-343,....

We are to find the nth term of the sequence

dn = ar^n-1

a is the first term = -1

r is the common ration = -7/-1 = -49/-7 = 7

n is the number of terms

Substitute

dn = -1(7)^n-1

dn = -7^n-1

hence the nth term of the sequence is dn = -7^n-1

The formula K=5/9(F−32)+273.15 converts temperatures from Fahrenheit F to Kelvin K.
FromTheMoon [43]

Answer:

a.  F = (9/5)(K - 273.15) + 32

b.  F = 32°F

Step-by-step explanation:

K=5/9(F−32)+273.15

F = (9/5)(K - 273.15) + 32

F = (9/5)(<u>273.15</u> - 273.15) + 32
