O B.
B.
x y²
- = 1
3 6
O C. y = x
O D. y = cos(x) - 2

damm bro the struggle

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
