What is f(x) = 2x2 28x – 5 written in vertex form? a. f(x) = 2(x 7)2 – 19 b. f(x) = 2(x 7)2 – 103 c. f(x) = 2(x 14)2 – 14 d. f(x) = 2(x 14)2 – 98

step-by-step explanation:

your answer is a

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
